Title: Go problem practicing apparatus
Inventor: ISHIKAWA MASAYUKI
IPC: A63F3/02
Filed: 1994-11-16
Abstract: PURPOSE: To make it possible to train by placing actual go pieces on a transparent sheet on which a go problem figure is written, and to obtain a real ambience of playing go, and increase the practice effect, by making a sheet on which a necessary number of longitudinal and lateral lines to form the measures whose distance and interval are almost specific sizes is printed, in a transparent sheet. CONSTITUTION: A sheet S for go problem training is a transparent sheet on which a necessary number of longitudinal and lateral lines to form measures having the distance and the interval about 23mm are printed. As a result, when the points P of a sheet S printing a go problem such as the figure, for example, are fitted to the four corners of a go board by turning the sheet S up and down, a problem figure of 8 patterns is obtained, and a real training can be carried out by using go pieces for go playing with the diameter 20mm. The relation of black pieces and white pieces to form various patterns is as the relation of the North Star and the Star bear in the sky, and the expression of the go problem figure is changed by the positions of the corners of the go board, even though almost similar cases are generated.  Consequently, when a problem of 8 patterns can be solved correctly, the true meaning of the original go problem can be mastered almost perfectly.

Title: Thermally coloring material
Inventor: TANABE HISANORI
IPC: B41M5/337
Filed: 1988-12-23
Abstract: PURPOSE:To enable color to be developed even at a comparatively low temperature by adding a specific t-butylester group as a color developer when a thermal activator selected from among aromatic organic acid salts with a specific sulfonium group and an ammonium group generating specific cations respectively are allowed to be present together with an electron-donative coloring organic compound and develop color by heating. CONSTITUTION:A compound with a t-butylester group at a higher boiling point than its useable temperature as a color developer for an electron-donative coloring organic compound is allowed to be present together with an electron-donative coloring organic compound. In addition, thermal activators selected from among aromatic sulfonium organic acid slats expressed by formula I and aromatic ammonium organic acid salts expressed by formula II are allowed to be present together. At the same time, polymerized materials for forming a film without any acidic group are added as essential components. If the t-butylester group is allowed to be present together as described above, the cation triggers rapid decomposition of the t-butylester group to generate carboxylic acid and isobutane. Therefore, color development takes place even at a comparatively low temperature and economically low-cost manufacture of the subject material is ensured.

Title: Oil application adjustment of electrostatic oil application device
Inventor: SHIDA NAOYA
IPC: B05D1/40
Filed: 1989-12-18
Abstract: PURPOSE:To prevent oil application irregularities by allowing the number of rotations of a pump at a specified acceleration speed by which a supply amount can be obtained which exceeds an application oil supply amount obtained from a line speed signal and an oil application amount setting signal based on a speed acceleration signal. CONSTITUTION:If the transport of a belt-like metal plate 1 is started and its transport speed is accelerated, the number of rotations of a pump 5 which supplies an application oil to an electrostatic oil application device 4 is increased at a fixed accelerated speed which allows a feed amount in excess of an application oil supply amount obtained from a line speed signal and an oil application amount setting signal connected based on the transport speed of the belt-like metal plate 1. Consequently, there occurs no trouble such as an excess shortage of application oil supply to the belt-like metal plate 1 due to a time delay from the variation of the number of rotations of the pump 5 to the change of the amount of atomized application oil from the electrostatic oil application device 4 to an appropriate spray amount for the variation of the number of rotations of the pump. In addition, when the transport speed of the belt-like metal plate 1 is reduced, the pump 5 is gradually adjusted to a constantly reduced speed by which the supply amount below the application oil supply amount level set based on the line speed signal and the oil application amount setting signal is obtained.

Title: Dust cover structure of ball joint
Inventor: OKADA YASUAKI
IPC: F16C11/06
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To reliably ensure sealing ability of a dust cover even during in the cold state. SOLUTION: A plurality of protrusion parts 74 protruded to the knuckle arm 22A side are formed on the part, positioned facing the lower end of the knuckle arm 22A, of a dust cover 46. Thereby, during bounding and rebounding of a suspension, deposited ice is crushed by the protrusion parts 74. Thus, deposited ice is prevented from growing and forcibly pressing downward the upper end part of a dust cover 46. As a result, sealing ability of the upper end part of the dust cover 46 is reliably ensured even during in the cold state.
