Title: Light amplifier
Inventor: SAITOU MASATOSHI
IPC: H01L31/14
Filed: 1981-09-29
Abstract: PURPOSE:To stabilize electric characteristics, to improve the heat resistance and to perform no pollution of a light amplifier by employing as a photoelectric cell an amorphous silicon in a photoconductive layer or a rectifying layer. CONSTITUTION:A photoconductive layer is obtained by forming of one type or multilayer junction, and has wide utility such as a photoconductive layer combined with rectifying operation, or a photoconductive layer combined with photovoltaic operation. Since a-(amorphous)-Si has large bonding force, its electric characteristics do not alter up to high temperature of 300 deg.C, do not depend on  the environment of the periphery, but can obtain extremely stable operating  characteristics. In case of high voltage from the voltage vs. current characteristics of the a-Si, when it is once emitted by the light, the resistance decreases,  and even after the light is interrupted, a light emitting element can continue the emission of the light for the prescribed period. The a-Si used as the photoconductive layer has large ratio of photoconductivity/dark conductivity such as  10<3>-10<5>, being excellent to CdS.

Title: Manufacture of electron gun for cathode-ray tube
Inventor: HOSHINO FUMITAKA
IPC: H01J9/18
Filed: 1992-06-16
Abstract: PURPOSE:To extract an spacer from a bead mount after assembly, allowing no damage on a grid by putting a spacer made of high heat conduction material at least at one position among plural grids and a cathode supporting body. CONSTITUTION:Spacers 20a-20f made of high heat conduction material such as Al are interposed among grids G1-G6 and cathode supporting bodies Ka, Kb, Kc. When the grids are mounted on a insulating supporting body BG softened through heating, the temperature of the spacers are quickly raised so that the thermal expansion amount of the spacers are increased when the temperature of the supporting body BG reaches softening point temperature or less. Accordingly, when the temperature of an assembled bead mount reaches room temperature, the thermal contraction amount of the supporting body BG, the grids and the spacers is offset so as to reduce compression force applied to the spacers. Therefore the spacers can be extracted without damaging the grids. Thereby, it is possible to manufacture easily the electron gun of a cathode-ray tube having an excellent voltage breakdown characteristic.

Filed: 1983-08-25
Abstract: PURPOSE:To attain head positioning with high accuracy independently of track deflection by obtaining a track deflection data from the servo information of a specific track and also obtaining the track deflection information while interpolating the data between each servo sector. CONSTITUTION:The head 33 reads the servo information from 32 servo sectors 17 at one revolution of a disc 11 at the position of a stopper, obtains an X signal (difference of position signals) at each sector and stores the result to a memory 36. The X signal is a track deflection data. A CPU35 calculates an average value of the data and adjusts that the value is within a prescribed range. The data obtained next is applied with interpolation so as to form the track deflection information. That is, in taking adjacent data in Fig. S as Xi, Xi+1, both data are tied by a straight line as shown in Fig. W, 9 data are obtained by dividing the line segment into 10, and they are stored in the 9 storage locations between the Xi and the Xi+1 in the memory 36. The interpolation is conducted by the CPU25. This operation is applied to all adjacent data so as to obtain 320 sets of track deflection information.

Abstract: PURPOSE: To make it possible to obtain a proper exposure at all times by detecting a mechanical  error which occurs when a diaphragm mechanism is controlled, utilizing the information of diaphragm value actually stopped down, and counting for correcting a shutter second time by a proper or improper quantity of this diaphragm value.   
     CONSTITUTION: In case the diaphragm control of exposure time priority, film sensitivity value set  by SW4 and brightness value of object from photo-detector element 1 via amplifier 2 are added in  the addition counter 3 to memorize it in the latch 5. Proper diaphragm value F is counted from  the added value and exposure time value set by SW8 in the diaphragm value count circuit 6,  whose output causes diaphragm value display meter 9 to swing. Indicator needle of the meter 9 is  suppressed synchronously with the release operation, and diaphragm mechanism 11 is stopped  down by diaphragm control mechanism 10 with the indicated value as its reference. Information  of diaphragm value F' which may contain the error acturally stopped down is detected by SW12  which sets diaphragm value in coupling with the diapragm mechanism 11. When timing SW ST  is made OFF by this detection, input 7b is subtracted from input 7A per unit time one pulse in the  subtraction counter based on the information of diaphragm value F' given to input 7B. Thus the  corrected exposure time when the output becomes zero is obtained.
