Title: Photosensor
Inventor: KATO SEIICHI
IPC: H01L31/10
Filed: 1992-06-08
Abstract: PURPOSE:To decrease a dark current, detect blue range light with a high sensitivity, and further prevent a reduction in sensitivity for red range light. CONSTITUTION:A photosensor is successively formed with three layers of amorphous semiconductor layers 102, 103, 104 on an n-type crystal silicon layer 101. When blue range light is incident, pairs of electrons and holes are generated in each of the amorphous semiconductor layers 102, 103, 104 to be a signal current without re-coupling these, thereby detecting the blue range light with an excellent sensitivity. While, when red range light is incident, as the amorphous semiconductor layers 102, 103, 104 are thin, even if the red range light transmits through them, optical carriers, namely pairs of electrons and holes, are generated due to an empty layer expanding continuously to an n<-> crystal silicon part 111 of the crystal silicon layer 101 to be a signal current without re-coupling them, thereby detecting even the red range light with an excellent sensitivity.

Title: Disk carrying table
Inventor: MATSUNAGA TATSUHISA
IPC: G11B17/035
Filed: 1988-07-14
Abstract: PURPOSE:To cope with a single compact disk as well by providing a supporting spring for the relief hole of the optical pickup of a disk player which can cope with three kinds of disks of a compact disk, compact disk video, and laser disk. CONSTITUTION:The inner peripheral surface 6 of a hole 5 for reliefing an opti cal pickup is formed to a circular-arc form in corresponding to a single compact disk (CD) 16 and a CD supporting spring 7 is provided in the vicinity of the disk center of the hole 5. The flat section 20 of the spring 7 is fixed to the rear side of a tray 1 and arm sections 8 and 9 of the spring 7 are bent upward from the line B. When the disk 16 is placed on the tray 1, the arm sections 8 and 9 are not bent because the disk 16 is light in weight and the disk is held in a tilted state. Therefore, the disk 16 can be carried inward without touching a CD aligning hub. In the case of the other kind of disks, the spring 7 is bent downward due to the weight of the disks and the disks are horizontally set in respective guide grooves. Thus this disk carrying table can cope with disks including single CDs.

Title: Pulse-width modulating circuit for driving load
Inventor: JIERI KEI GOFU
IPC: H02M7/5387
Filed: 1991-07-16
Abstract: PURPOSE: To obtain the pulse width modulation(PWM) circuit in which current ripple is reduced and a frequency band width is extended by comparing a dither signal used for a pair component with a dither signal used for other pair component and deviating the phase of the signal timewise. CONSTITUTION: A dither signal shifted timewise is compared with a noninverting command signal in place of using an inverted command signal to obtain a 'prime (main)' signal. In this case, the amount of timewise shift is t/2 (t is a period of a dither signal). Signals x, x' being outputs of comparators are given to complement generating circuits 44, 45, from which output signals y, y' are generated. Since the signals y, y' are obtained through the processing of complement only, the signals y, y' are subordinated to the signals x, x'. Then the signals x, y are given to a bridge A48, while the signals x', y' are given to a bridge B50. A load 32 is connected to the two bridges 48, 50.

Title: Touch panel
Inventor: IKURA KENICHIRO
IPC: G06F3/041
Filed: 1990-07-02
Abstract: PURPOSE:To effectively prevent a conductive film from being broken by putting a protective film in pushing-operation side of a flexible film while having an elastic layer between them. CONSTITUTION:A protective film 24 is put in the pushing operation side of a flexible film 21 while putting an adhesive layer 2 between them. Consequently, the film which receives strain and stress at the time of input is only the protective film 24 and the stain and stress work only indirectly on the flexible film 21 and conductive films 6, 6, 6 are thus prevented from being broken effectively. Also, the adhesive layer 2 works as a kind of cushion between the flexible film 21 and the protective film 24 and the flexible film 21, that is conductive films 6, 6, 6, is effectively prevented from being damaged and input durability of a touch panel is thus improved.
