Title: Solid-state image pickup device
Inventor: MATSUMOTO KAZUYA
IPC: H04N5/335
Filed: 1984-04-17
Abstract: PURPOSE:To easily obtain an output which is obtained by taking the differential between a photoreceptor signal and dark signal, by constituting a differential circuit by using one piece or one line of dummy picture string, picture elements at the first section of the same line as read out picture elements, etc., in the same photoreceptor device chip. CONSTITUTION:When the horizontal scanning signal phiG1 of a vertical scanning circuit 66 becomes a reading-out gate voltage VphiG, LSIT groups 60-11-60-1n connected with a line 61-1 and a dummy transistor 68 are selected and horizontal selecting transistors 63-1-63-n are successively turned on by the signal of a horizontal scanning circuit 67, and then, signals of the LSIT groups 60-11-60-1n are successively outputted from a video line 64. When the signal phiG1 goes to a high-level resetting gate voltage VphiR, LSIT groups 60-21-60-2n connected to another line 61-2 are selected and read out. When a vertical scanning signal phiG2 during the reading out period, the dummy transistor 68 is reset at once. In the same way, the optical signal of the LSITs and the dark signal of the transistor 68 are read out.

Title: Inverter device, discharge lamp turn-on device and illuminating device
Inventor: MITA KAZUTOSHI
IPC: H05B41/24
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To stop the operation of an inverter without fail when a load is removed, even if there is a floating capacitance by including an impedance means that is installed in a load circuit and acts, so as to virtually prevent a current due to floating capacitance between wiring paths from being passed through a current transformer when the load is removed. SOLUTION: An impedance circuit 6 consists of a capacitor CB, the capacitance of which is larger than the floating capacitance Cs between wiring paths, and is parallel-connected with the secondary winding of an output transformer T. If a load 4 is removed when an inverter device is oscillating, a series circuit comprising a current transformer CT and a floating capacitance is bypassed or short-circuited by the impedance circuit 6. Increase in secondary open-circuit voltage is prevented by the shifting of the resonance frequency on the secondary side of the output transformer due to the addition of the impedance circuit, so that current hardly passes through the current transformer CT. For this reason, current feedback is virtually eliminated, and the operation of the inverter circuit 3 is stopped.

IPC: H01L29/84
Filed: 1981-05-20
Abstract: PURPOSE:To obtain a device which has less offset drift without increasing the height of a pedestal, by making the shape of the sticking end surface of the pedestal to a semiconductor diaphragm smaller than that to a fitting base. CONSTITUTION:The shape of the sticking end surface of a pedestal to a semiconductor diaphragm is smaller than to a fitting base.

Abstract: PURPOSE:To make an actual rotation number follow accurately an engine rotation number command value, by correcting the command value which is to be outputted, on the basis of a data showing an actual opposition relation between the actual engine rotation number acquired by actually driving an engine and the command value. CONSTITUTION:A controller 10, when it is detected that a hydraulic actuator 12 is totally under a neutral condition NT, executes an engine correction command value registration mode, and an engine rotation number command value Nc changing properly is inputted into an engine 1, and drive is made actually.

Abstract: PURPOSE: To maintain excellent print quality even when a simple and inexpensive electric power source is used, by preventing a hammer-driving electric power source from being overloaded by inhibiting printing operation for a certain period after digits are continuously printed as many as a constant number.  
     CONSTITUTION: When the count value of counter 45 reaches preset numeral N, an inhibition signal is sent out onto line 45a and inhibition gate 41 closes. For the following certain time T, no hammer set pulse is output onto line 41a even if a coincidence 34 signal is output onto line 34a. Namely, since no print operation is carried out for certain time T, the time when a hammer voltage dropping in printing recovers is secured and the hammer voltage of hammer driving electric power source 21 in process of decreasing up to that time because the voltage has driven as many print hammer coils 23 as N never falls further [below V 0 (MIN)], so that it can recover up to orginal voltage V 0 (TYP) in the period of time T. Therefore, excellent print quality can be obtained even by using an inexpensive hammer-driving electric power source that has not any constant-voltage control circuit, etc.

Abstract: PURPOSE:To enable precise control of a surface function by forming active sites having different chemical reactivities on the surface of a silicon single crystal, fixing a metal carbonyl compound corresponding to the reactivities of the respective sites, subsequently carrying out decarbonylation and finely modifying the single crystal surface. CONSTITUTION:Active groups (e.g. OH group or NH2 group) are planted on the surface of a silicon single crystal by dissociative adsorption of a compound having the active group utilizing chemical reactivities of the silicon surface in order to form active sites having different chemical activities. A metal carbonyl compound [e.g. Co2(Co)8] corresponding to the respective reactivity is then physically adsorbed onto the above-mentioned active sites. The metal carbonyl compound is fixed to the respective site by chemical bonds using light or heat and then subjected to decarbonylation to form an arrangement of metals. The surface of the silicon single crystal is finely modified thereby, thus producing the objective surface-functional material having a new catalytic function, specific magnetic characteristics, etc.
