Title: Optical recording medium
Inventor: YANO EI
IPC: G11B7/24
Filed: 1987-09-18
Abstract: PURPOSE:To enable a reversible optical recording with high recording shelf- stability and long-term stability, by utilizing the photochromic reversible optical reaction of a specific dimerized dioxypyrimidine derivative. CONSTITUTION:A monomolecular film of a dimerized dioxypyrimidine derivative shown by a formula I is accumulated on a substrate. In the formula I ; R1 and R2 independently represent hydrogen, lower alkyl, and 16-24 C alkyl, and R3 represents hydrogen or lower alkyl. Here, the lower alkyl is 1-3 C alkyl, especially 1-2 C alkyl. The pyrimidine derivative is obtained by a method wherein a thymidine or a thymine derivative is caused to react with a long-chain alkyl halide to produce an alkyl derivative and this is dimerized by light. The compound can form a monomolecular film on a water surface. This film is accumulated on the substrate, for example, by an LB method, whereby a film of large area with the satisfactorily oriented part of the dimerized dioxypyrimidine derivative is obtained. This film is to be a reversible optical recording medium which allows the writing or erasing to be repeatedly carried out with a low energy.

Title: Tilt stand
Inventor: IWATA MAKIO
IPC: F16M11/12
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To facilitate the adjustment operation of a mounted thing by locking it with a locking member. SOLUTION: In several combinations of a rotary table 11 and a tilt board 12 which are mounted on a base 10, first, an engaging nail of the table 11 engages an circular opening 17 in the center part of the base 10 and the table 11 freely rotates. Then, a plate-shaped protrusion 38 of the board 12 is inserted into a slit 30 of the table 11. The protrusion 38 freely moves in a tilt direction in the slit 30 by engaging its tip with an engaging member 21 at the end of a coil spring 20, and the maximum degree is restricted by the length of the slit 30. The other end of the spring 20 is locked to a pin that is placed on the bottom of the table 11. The spring 20 pulls a mounted thing on the board 12 forward and balances with tilt force that is caused by the gap which the center of gravity of the mounted thing has against the tilt center.  By this, an angular moment that accompanies with the deviation of the center of gravity is denied and a smooth tilt movement is possible.

Title: Method for changing and managing system time of computer system
Inventor: SEKIMOTO TAKAYUKI
IPC: G06F1/14
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce the processing load of respective processes and to improve the processing efficiency of the whole system by informing respective processes of a change in system time. SOLUTION: When time changing information is inputted from a system time managing part 6, a time change correspondence processing routine 5a executes prescribed time change correspondence processing. At the time of inputting a system time changing instruction including changed time t1 specified by an operator e.g. a system time changing process 3 sends the changed time t1 to the managing part 6. At the time of inputting the time changing command, the managing part 6 informs respective processes 2 of the time change and then changes the system time (t) of a system clock 1 based upon the inputted changed time t1 . Since it is unnecessary to always monitor the system time (t) inputted from the clock 1 in each regulated period and judge a time change, the processing load of the processes 2 can be reduced.
