Patent JP-2000322765-A (JP)
Title: Optical recording medium
Inventor: IWAKI TETSUO
IPC: G11B7/24
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To secure reliability in the outer and inner edge part of a disk susceptible to stripping, by making the external size of a light transmitting cover layer, which is stuck together with a substrate, smaller than that of the substrate. SOLUTION: Since the outer diameter of a light transmitting cover layer 2 is formed smaller than that of a substrate 1, the part stuck together is not exposed to the outer peripheral end face of a disk. As a result, a shock imparted to the disk end face is not directly transmitted to the stuck part. Consequently, this structure increases strip resistivity of the cover layer 2 against a shock imparted to the disk end face. Further, since the inner diameter of the cover layer 2 is formed larger than that of the substrate 1, the stuck part is not exposed to the inner peripheral end face of the disk. As a result, the cover layer 2 is less susceptible to stripping due to a possible contact in chucking the disk. In this case, the inner edge part is provided with an area where the substrate is exposed; therefore, chucking with this area enables highly accurate chucking.

Title: Electrochromic display device
Inventor: HACHIMAN AKIHIRO
IPC: G02F1/153
Filed: 1989-05-24
Abstract: PURPOSE:To reduce oxidation/reduction reaction between display electrodes of adjacent picture elements and between counter electrodes and to prolong display life by making the driving timing of plural picture elements in one direction different from the driving timing in the opposite direction. CONSTITUTION:A picture element PBa is driven forward and backward with electricity through bridge-connected transistors TRa, TRb TRc and TRd. The TRa and TRb are PNP type and the TRc and TRd are NPN type. The TRa is controlled with a signal c1 from a control circuit 1; and the TRb is controlled with the inversion of the signal c1, the TRc is controlled with signal d1 from the control circuit 1, and the TRd is controlled with the inversion of the signal d1. Thus, the driving timing of plural picture elements in one direction is made different from the driving timing in the opposite direction, so the oxidation/ reduction reaction between the display electrodes and between the counter electrodes of plural picture elements is precluded to prevent the deterioration of an EC material from being accelerated.

Abstract: PURPOSE:To prevent an arm from shortcircuiting by turning OFF either one of positive and negative pole side semiconductor switch elements of a bridge circuit, and operating ON, OFF only at the other semiconductor switch element. CONSTITUTION:The polarity decision comparator 21 of a current command value I* is provided, its output and the output of a comparator 11 with hysteresis are input to an AND gate 24, and a positive pole side transistor (Tr) 51 is operated ON, OFF through a base driver 14 by the calculated result. The outputs of the comparators 21, 22 are input through individual inverting elements 23, 22 to an AND gate 25, and a negative pole side Tr 52 is turned ON, OFF through a base driver 17 by the calculated result. Thus, one Tr remains OFF state corresponding to the output of the comparator 21, and the other Tr is turned ON, OFF according to the output of the comparator 11.

Abstract: PURPOSE:To prevent the change of luminance at the time of color adjustment by providing a means to change optionally the coefficient of a conversion matrix for executing converting operation in a signal converting means. CONSTITUTION:At the time of the adjustment of hue, a ROM address generation circuit 10 supplies a prescribed address signal to a ROM 11 by a switch circuit 9. Then, the conversion matrix and a coefficient (k) for the luminance are read out. The coefficient (k) is supplied to an amplification/attenuation circuit 12, and a luminance level is adjusted. Luminance level adjusted R,G,B signals outputted from the amplification/attenuation circuit 12 are converted respectively, and are supplied to a printing part 7 through a selector switch. If the coefficient to raise the luminance so as to agree with a printed picture is made before hand to come to be selected, the color of the printed picture can be easily adjusted so that the effect of a landscape is exhibited. Thus, the luminance never changes at the time of the color adjustment.

Abstract: PURPOSE:To adjust a phase digitally by calculating the difference between the high-order 6-bit data of interpolation data of a low-order channel and the 6-bit data from the 5th bit of interpolation data of a high-order channel. CONSTITUTION:The initial value Ci of correction data is set to zero and the difference DELTACi between the data Bi of the interpolation data Di of the high-order channel at specific sampling time and the data Ai+1 of the interpolation data Di+1 of the interpolation data of the low-order channel is calculated. Then when the absolute value of the difference is larger than the set value, Ci+DELTACi is used as new correction data and the data Di of the high-order channel at next sampling time is corrected with the correction data Ci. Similarly, such correction data that the absolute value of the difference DELTACi is smaller than the specific value is found. Similarly, correction data are found by adjacent channels and when the absolute position of a rotary shaft is detected, the data Di is corrected with the data Ci and the high-order four bits of interpolation data of the respective channels after the correction are put together to generate and output absolute position data on the rotary shaft.

Title: Bar code reader
Inventor: TAWARA TAKAO
IPC: G02B27/00
Filed: 1985-06-18
Abstract: PURPOSE:To prevent bar codes from uneven light irradiation and to increase the effective light projection upon the bar codes by arranging a wide angle lens array for diverging light on the almost same direction as the array direction of illuminating light sources and a photodetecting element array for reading out the reflected light of the bar codes. CONSTITUTION:The reflected light from the bar codes 31 is stopped by a diaphragm means 40, and even if the positions of the bar codes 31 are slightly shifted, the reflected light can be sufficiently read out because the focal depth is increased by said stopping. Light passed through the diaphragm means 40 is converged by a sylindrical lens 60 and forms its image on the photodetecting element array 51. In this case, the cylindrical lens 60 converges the light on the direction rectangular to the longitudinal direction of the array 51 without changing the light dispersing state in the longitudinal direction of the array 51. If the cylindrical lens 60 does not exist, light deviated from the array 51 is received by the array 51, so that the array 51 can obtain more brighter reflected light.

Title: System for controlling printer control code

Filed: 1987-05-27
Abstract: PURPOSE:To make programming fitted to a printer desired to be outputted unnecessary, by converting a symbolic control code for the printer described in a program to a physical control code adaptive for a targeted printer. CONSTITUTION:In output data to the printer delivered from a program 10 to a printer control part 20, a printer control code such as a line feed pitch, a character pitch, etc., are included as a symbolic value. A printer control code conversion mechanism 30 converts a supplied symbolic control code to the physical control code adaptive for the targeted printer based on the designation information of the printer, and returns it to the printer control part 20. By outputting the physical control code converted in such way to the targeted printer, a designated printer out of the printers 41-43 outputs data according to the above operation. In such a way, it is possible to perform the programming without being conscious of the printer desired to be outputted.

Abstract: PURPOSE:To absorb the vibration of an equipment and an ultrasonic transmitter and receiver itself and prevent a malfunction from occurring owing to an unnecessary reflected wave generated in a transmission and a reception by arranging a buffer body around the mounting portion of the support of a horn device. CONSTITUTION:A ultrasonic transmitter 5 radiates an ultrasonic signal in the air and is accommodated in the fixed portion 8 of a horn device 7 via a foaming buffer member 6.
