Patent JP-H03147989-A (JP)
Title: Cylinder lock
Inventor: KAMATA NOBUAKI
IPC: E05B27/08
Filed: 1989-11-02
Abstract: PURPOSE:To prevent illegitimate unlocking by fitting a lock with a mechanism whereto a key is inserted into a key hole with projections of the key fitted to a plurality of notch grooves that are provided on the peripheral edge of the key hole, and lock- fastening pins are retracted by operation of driving pins that are pushed with the projections of the key. CONSTITUTION:As a key 50 is inserted into a key hole 22 with projections 53 of the key fitted to plurality of notch grooves 221, 221 that are provided on the peripheral edge of the key hole 22, a recess in the front end of the key 50 is inserted to the lock shaft 40 and an engaging projection 52 on the innermost part of the recess and an engaging indent 44 on the front face of the lock shaft 40 are engaged together. At this time, each of driving pins 43 is pushed with projections 53 of the key 50 and lock-fastening pins 35, 35, each of which forms a counterpart to each of the driving pins 43, retreat to the inside of a lock main body 30, disengaging the lock shaft 40 from the lock main body 30. With the key 50 turned under such condition, the lock shaft 40 turns together with the key 50 through the engagement of the engaging indent 44 and the engaging projection 52, making the unlocking available. Thereby it becomes very hard to make a duplicate key, resulting in prevention of illegitimate unlocking.

Abstract: PURPOSE:To manufacture a material for thermoelectric conversion element having superior thermoelectromotive force, by pulverizing an alloy material in a foil-like state prepared by melting specific amounts of Mn or Co together with Fe and Si ad subjecting the resulting molten metal to super rapid cooling. CONSTITUTION:Mn (<3wt%) or <3.3wt% Co is added to a material in which Fe and Si are mixed practically half-and-half to undergo melting, and the resulting molten metal is sprayed onto a rapidly rotating roll made of steel having a cooling device, by which the molten metal is super rapidly cooled at a cooling rate of 10<3> deg.C/sec so as to be formed into flaky foil. The foil is crushed by means of a ball mill into a pulverized powder of <=100mum, which is subjected to coil pressing and the resulting green compact is further sintered at 1,100 deg.C in an Ar atmosphere. In this way, the thermoelectric conversion element combining high fracture strength with superior thermoelectromotive force can be obtained.

Title: Flame-retarding resin composition
Inventor: WATANABE SUSUMU
IPC: C08K3/16
Filed: 1986-12-02
Abstract: PURPOSE:To improve the flame retardancy and safety of a synthetic resin without detriment to its inherent mechanical strength by decreasing the amount of antimony oxide to zero or a small level, by mixing a resin composition formed by mixing the synthetic resin with a halogenated flame retardant with active alumina as a flame-retarding aid. CONSTITUTION:100pts.wt. synthetic resin is mixed with 1-100pts.wt. halogenated flame retardant and 1-50pts.wt. active alumina of a BET specific surface area >=100m<2>/g as a flame-retarding aid. Antimony oxide in an amount not causing a problem such as smoke evolution can be used in combination with said active alumina as a flame-retarding aid. A combination of the two is effective, especially, for imparting flame retardancy to a resin of a high calorific value such as polyethylene or polypropylene. The mixing ratio in this case is such that 1-100pts.wt. halogenated flame retardant, 1-30pts.wt. antimony oxide and 1-30pts.wt. said active alumina are used per 100pts.wt. synthetic resin.

Title: Movement detection circuit
Inventor: HIYOSHI AKIO
IPC: A63B24/00
Filed: 1986-12-02
Abstract: PURPOSE:To detect the characteristic of the movement of the limbs of a person, by a method wherein the acceleration signal from the acceleration sensor mounted to the person is integrated on the basis of a characteristic period to be converted to a speed signal which is, in turn, integrated to be converted to a distance signal. CONSTITUTION:When an acceleration signal AI is supplied to a phase shift/peak detection circuit 16, an output signal U rises and falls at the time when the amplitude of the signal AI becomes the max. value. When the signal U rises, the output signal DL of a delay circuit 22 rises and falls so as to delay by a predetermined time from the falling of the signal U. During a time when the signal DL is a '1' signal, lead relays 6, 13 are excited to become an open state. During this time, the signal AI is integrated by an integration circuit 2 to output a signal DV. Since the signal DV is integrated over an acceleration increase period, said signal DV shows the max. speed at the point of time when the acceleration increase period of an article to be measured is finished. The signal DV is integrated by an integration circuit 8 to output a signal DD. The signal DD shows the moving distance of the article to be measured until acceleration becomes max. As mentioned above, since integration is performed during the characteristic (acceleration increase) period of the signal AI, the characteristic of operation can be detected.

Title: Liquid crystal display device
Inventor: YANAGAWA KAZUHIKO
IPC: G02F1/1337
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the inconvenience that an oriented film is formed while covering the group of signal terminals by a cause such as the dislocation of a mask by comparing the contour part of the oriented film on one transparent substrate side with the contour part of the oriented film on the other transparent substrate side and positioning and forming the oriented film to the side away from the signal terminals. SOLUTION: An oriented film 11 on a transparent substrate 1 side, on a group 4G side of video signal terminals, is formed while securing a sufficient distance from the group 4G in comparison with an oriented film 12 on a transparent substrate 2 side. That is, on the group 4G side of the video signal terminals, the oriented film 11 on the transparent substrate 1 side has a distance W corresponding to >=1/3 of one pixel in comparison with the oriented film 12 on the transparent substrate 2. Therefore, in the case of forming the oriented film 11, the probability that the oriented film 11 is formed while covering a part of the group of scanning signal terminals or the group of the video signal terminals is extremely small and the yield of manufacture can be increased.
