Docket #:2015-15
This Proposal has been approved, and is now a Milestone
To the proposer’s knowledge, is this achievement subject to litigation?
Is the achievement you are proposing more than 25 years old?
Yes
Is the achievement you are proposing within IEEE’s designated fields as defined by IEEE Bylaw I-104.11, namely: Engineering, Computer Sciences and Information Technology, Physical Sciences, Biological and Medical Sciences, Mathematics, Technical Communications, Education, Management, and Law and Policy. Yes
Did the achievement provide a meaningful benefit for humanity? Yes
Was it of at least regional importance? Yes
Has an IEEE Organizational Unit agreed to pay for the milestone plaque(s)? Yes
Has an IEEE Organizational Unit agreed to arrange the dedication ceremony? Yes
Has the IEEE Section in which the milestone is located agreed to take responsibility for the plaque after it is dedicated? Yes
Has the owner of the site agreed to have it designated as an IEEE Milestone? Yes
Year or range of years in which the achievement occurred:
1933
Title of the proposed milestone:
Invention of Temperature-Insensitive Quartz Oscillation Plate Enabling Highly Stable Communications and Clocks, 1933
Plaque citation summarizing the achievement and its significance:
200-250 word abstract describing the significance of the technical achievement being proposed, the person(s) involved, historical context, humanitarian and social impact, as well as any possible controversies the advocate might need to review.
IEEE technical societies and technical councils within whose fields of interest the Milestone proposal resides.
In what IEEE section(s) does it reside?
IEEE Tokyo Section
Exective Committee Member
Chair of History Committe, IEEE Tokyo Section
Member of History Committee, IEEE Japan Council
Haruo Okuda
IEEE Organizational Unit(s) which have agreed to sponsor the Milestone:
IEEE Organizational Unit(s) paying for milestone plaque(s):
IEEE Organizational Unit(s) arranging the dedication ceremony:
IEEE section(s) monitoring the plaque(s):
Milestone proposer(s):
Proposer name: Kenichi IGA
Proposer email: Proposer's email masked to public
Proposer name: Taiji Nishizawa
Proposer email: Proposer's email masked to public
Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.
Street address(es) and GPS coordinates in decimal form of the intended milestone plaque site(s):
2–12–1, O-okayama, Meguro-ku, Tokyo, 152-8550 Japan
Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.
Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need.
Are the original buildings extant?
Yes, the Main Building of the Institute. (See photograph in Fig. 12 Media:Fig_12.pdf)
Details of the plaque mounting:
In a special showcase at the Exhibition Room of the Institute Museum
How is the site protected/secured, and in what ways is it accessible to the public?
The Museum is open to the public on weekdays from 10:30 to 16:30. (Closed nights and holidays.)
Who is the present owner of the site(s)?
Tokyo Institute of Technology National University Corporation
What is the historical significance of the work (its technological, scientific, or social importance)? If personal names are included in citation, include justification here. (see section 6 of Milestone Guidelines)
What obstacles (technical, political, geographic) needed to be overcome?
What features set this work apart from similar achievements?
In 1932, when Koga established his precise theoretical analysis of thickness vibration of anisotropic quartz crystal, no similar theory existed. Therefore, Koga's theory [2 and 3] was readily adopted in the field together with the practice of rotating the cutting angle around the crystallographic axis. This contributed worldwide to the application of zero-temperature-coefficient quartz plates.</dev>,br />
In late 1929 and early 1930, several proposals appeared for realization of zero-temperature-coefficient plates. Among them, a ring-type plate was considered promising, however it was unusable in actual transmitters owing to delicate design constraints.
As explained, Koga concentrated on producing a zero-temperature-coefficient plate by rotating the cutting angle along the X-axis and realized an actual plate having a zero-coefficient in 1933 [7]. Similar work was being done in Europe and US, and this may be summarized as follows:Supporting texts and citations to establish the dates, location, and importance of the achievement: Minimum of five (5), but as many as needed to support the milestone, such as patents, contemporary newspaper articles, journal articles, or chapters in scholarly books. 'Scholarly' is defined as peer-reviewed, with references, and published. You must supply the texts or excerpts themselves, not just the references. At least one of the references must be from a scholarly book or journal article. All supporting materials must be in English, or accompanied by an English translation.
In the references listed below, Koga's affiliated university name “Tokyo University of Engineering” refers to the older English appellation of the present-day “Tokyo Institute of Technology”.
Supporting materials (supported formats: GIF, JPEG, PNG, PDF, DOC): All supporting materials must be in English, or if not in English, accompanied by an English translation. You must supply the texts or excerpts themselves, not just the references. For documents that are copyright-encumbered, or which you do not have rights to post, email the documents themselves to ieee-history@ieee.org. Please see the Milestone Program Guidelines for more information.
