Abstract: PROBLEM TO BE SOLVED: To make plural CD-ROM mediums utilizable at one teme by providing optical pickups corresponding to the number of sheets of packaged plural CD- ROMs and making the CD-ROM medium accessable while changing over the mediums. SOLUTION: When plural CD-ROM mediums are packaged in a CD-ROM device 20, medium information are read out with optical pickups 10 corresponding to respective mediums to be stored in a CD-ROM index storage mechanism 4. Necessary data are read out with respect to a data read-out request from a host side device 30 by searching out the position of a target CD-ROM automatically which refereing to the storage mechanism 4 and by controlling the position of an optical pickup 10 made correspond to the position of the CD-ROM. Consequently, since when the information of a desired CD-ROM are transmitted to the CD-ROM device 20, the medium is automatically searched out, the searching out of a CD-ROM is performed just as in the case an ordinary CD-ROM device is connected to the device 30 as to the host side device 30 and also the using of plural kinds of mediums is made possible.

Title: Liquid crystal display element and its production
Inventor: SHIBA HIDENORI
IPC: G02F1/1337
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To improve all of contrast, transmittance and sharpness characteristics and to improve the display quality by giving chirality to a liquid crystal material so that the liquid crystal has a twisted structure when voltage is applied, and orienting the liquid crystal in the parallel direction to the substrate. SOLUTION: A nematic liquid crystal having negative dielectric anisotropy with addition of a chiral agent is injected between a pair of substrates 1, 2 of a perpendicular orientation-type ECB mode liquid crystal display element. The surfaces of the substrates 1, 2 in contact with the liquid crystal are subjected to intensive orientation treatment in the parallel direction to the substrate surface. When no voltage is applied, all liquid crystal molecules 10 are oriented almost perpendicular to the substrate. however, the liquid crystal molecules 10 on the interface have a pretilt angle due to the orientation treatment in the parallel direction to the substrate. When voltage is applied on the cell, the liquid crystal molecules 10 are tilted to give large retardation to transmit light. In this process, the liquid crystal molecules show a twisted structure between substrates due to the chiral agent.

Filed: 1980-03-17
Abstract: PURPOSE:To transmit a correct output to the control variable at all times, by locking the outputs of computers of opposing system with the output of computers of master/slave system, in the controller of computers in multiplex constitution. CONSTITUTION:Operation devices 2, 12 make operational processing based on the input data in both computers 14, 15, and since the output from the output device 13 comes after a given time, the computer 14 regards the computer 15 as absense of output and outputs to the total output device 6 and transmits the lock signal 14S at the same time. Thus, the computer 15 gives no output after a given time, and the logical sum output delivered to the control variable 7 is the output of the computer 14. On the other hand, if the computer 14 is in failure and has no output, the computer 15 regards the computer 14 as absence of output, and it outputs to the output device 6 and transmits the lock signal 15S to lock the output of the computer 14. Thus, no erroneous operation processing is output from the output device 13.

Abstract: PURPOSE:To obtain a power amplifier where the distortion rate and efficiency are improved, by making it possible to set the bias of the amplifier according to fluctuation of a signal level independently of the signal frequency. CONSTITUTION:The input signal from terminal 1 is applied to transistors TR9, 10, which constitute a complementary push-pull circuit, through resistances 7 and 8 and is amplified, and after that, this amplified signal not only is applied to load 17 but also sets the base bias of TR9, 10 through full-wave rectifying circuit 2, peak detector 4 having a negative feedback circuit dependent upon resistance 15 and diode 14, and differential amplifier 6. Then, the output signal from emitter resistances 11 and 12 of TR9, 10 is fed back to differential amplifier 6 through differential amplifier 13. The output of peak detector 4 follows the input signal level rapidly due to reduction of the discharging time constant dependent upon the negative feedback circuit of resistance 15 and diode 14 when the input signal is reduced.
