Title: Optical-data recording medium and manufacture thereof
Inventor: SAITO OSAMU
IPC: G11B7/24035
Filed: 1990-11-30
Abstract: PURPOSE:To block the coloring reaction caused by the mutual diffusion and mixing during preservation and to improve preservation durability by mutually differentiating binders contained in a layer incorporating heat sensitive color former and a layer incorporating developer. CONSTITUTION:In a medium A, a layer incorporating heat sensitive color former 2, a layer 3 incorporating developer 3 and a protecting layer 4 are sequentially laminated and formed from the lower-layer side on a supporting body 1 comprising glass, metal, synthetic resin, paper or the like. The protecting layer 4 is transparent. When laser light L is cast from the side of the protecting layer 4, the insides of the layers 2 and 3 at the illuminated part are heated by the light-heat conversion. The heat sensitive color former and the developer in the layers 2 and 3 are locally fused and become the fluid state. The barrier of the binder matrix between both layers 2 and 3 is broken, and the color former and the developer are mutually diffused and mixed in the reaction. The required data are recorded with colored parts 5 formed by this reaction. Thus, the coloring reaction due to the mixing of both materials is prevented, and the preservation durability is improved.

Title: Inspection of brake force of vehicle provided with antilock control device
Inventor: TOKUNAGA MASAHIRO
IPC: B60T8/88
Filed: 1990-11-30
Abstract: PURPOSE:To perform accurate inspection irrespective of difference in brake pedal depressing force by sending a simulated control signal to a brake system, detecting the changes in the brake force, and judging whether or not the brake force values and their ratios are within a specified range. CONSTITUTION:A simulated driving condition is brought about by placing the front or rear wheels on a brake tester 30, starting an ABS control circuit 10 to drive the motor 31 of the brake tester 30 and rotate a roller 32. Antilock control is started by depressing the brake pedal. In a test unit 20, the control signal of specified pattern according to the program of an interface unit 23 generates pressure increasing command and pressure decreasing command by turns within a specified period of time. The changes in the brake force according to the control signals are detected with a brake force meter 33 and sent as electrical signals to a sequencer 24. The numerical operation section of the sequencer 24 calculates the absolute values of the brake force X (before pressure reduction), Y (after pressure reduction), and Z (after pressure increase). A judging section compares the brake force value Y and the ratio Z/X with respective reference values. If all of the values are within the ranges of judgment values, the brake force is judged to be normal.
