Revision as of 11:51, 19 December 2010
Name order
In my opinion, we should settle on the Japanese name order for Japanese people. (I know that there are equally good reasons to adopt one order or the other; this has been discussed for years in Wikipedia, and they were not able to come with a sensible rule.) Currently we have both: see Yoshihisa Maitani vs Kumagai Genji. In all the pages I made on Japanese cameras, I used the Japanese order for personal names, and I'm very reluctant to change that.

Japanese patents
The Japanese system makes a distinction between patents (特許, tokkyo) and utility models (実用新案, jitsuyō shin.an, literally "new idea with a practical application", a sort of "sub-patent"). They are numbered differently, and should be distinguished in the table. (I think other patent systems do the same, but I'm not sure.)
The first Japanese document (applied for in July 1939) was a utility model. It was originally applied for as a patent but was apparently requalified as a "utility model" by the patent office. (The publication says that the application date is the date at which it was applied for as a patent.)
As far as I understand, there are three dates for a (Japanese) patent: the application date, when the inventor applies for it (出現), the publication date, when the document (or maybe an abridged version) is published after it was examined (広告), and the grant date, when the patent is officially registered, presumably after nobody has objected on priority grounds and after a fee is paid. There is also a number corresponding to each stage: application number, publication number and final patent/U.M. number. The first two sequences are reset to one at each calendar year, hence the Sxx prefix (for Shōwa xx), only the final number is running in a single continuous sequence.
For the two early Japanese documents, we have:
| Country | Type | Application date | Application number | Publication date | Publication number | Grant date | Grant number | Title | Relates to camera model |
| Japan | Utility model (実用新案) | Jul. 1, 1939 (as a patent) | S15-17197 (as a U.M.) | Oct. 5, 1940 | S15-14673 | n.a. | 294734 | 写真機に於ける焦点調整装置 (Focusing control device in a camera) | Mamiya Six |
| Japan | Patent (特許) | Oct. 11, 1940 | S15-14993 | Aug. 15, 1941 | S16-4067 | n.a. | 146741 | 歯車連動装置に於ける歯隙の影響を解消する装置の改良 (Improvement to a device that cancels the effect of gear play in a gear train device) | Mamiya Six |
It is interesting to notice that Mamiya Seiichi filed for the patent six days after the previous one was published as a U.M. by the patent office. He seemingly expected to get a full patent; once he became sure that the application was downgraded to U.M. status, he re-applied for a patent covering a more restrictive portion of the design.
