Title: Production of se photoreceptor
Inventor: KONUMA SHIGEHARU
IPC: G03G5/08
Filed: 1978-11-22
Abstract: PURPOSE: To obtain desired surface potentials with low applied voltage by subjecting a substrate to oxidation heat treatment after formation of a PbS layer thereon then forming a Se layer.  
     CONSTITUTION: After PbS is vacuum evaporated on a metal substrate such as of Al, it is subjected to oxidation heat treatment for 30W60min at 100W300°C. Next, Se is evaporated to form a photoconductive layer. The PbS evaporated contains much Pb and has therefore the property of an n-type semiconductor but it becomes of p-type when subjected to oxidation heat treatment and since the Se photosensitive layer is able to provide high surface potentials, only low applied voltage is required in obtaining the desired surface potential, thus the Se photoreceptor which does not cause printing blurr, drop-out of prints, etc. at the printing is obtained.

Abstract: PURPOSE:To enable independent control of fuel injection amount, injection rate and injection timing, by providing two solenoid valves for feeding the control fuel related to the injection amount and injection rate and a lead angle mechanism for varying the compression slope position of cam. CONSTITUTION:Fuel is fed through an oil feed port 13 to a solenoid valve 8 for controlling the fuel injection amount and a solenoid valve 11 for controlling the injection rate by means of a pump. Upon feeding of fuel to the pump chamber 3, a shuttle 2 will move to the left by the distance corresponding to the feeding amount, while upon feeding of fuel to the pump chamber 4, a plunger 18, roller 20, roller 19 are expanded outwardly. Upon starting of contact between a compression roller of a cam 21 and roller 19, fuel in the pump chamber 3 is compressed to inject high pressure fuel into the combustion chamber. Fuel from the solenoid valve 11 empolyed for control of compression of the pump chamber 4 and the contact position (injection starting time) between the cam 21 and the roller 19 is discharged to the low pressure side. The fixed position and the leading angle position of the cam 21 is controlled by the current to the coil.

Title: Digital-analog secondary converter
Inventor: MERUKIOORE BURUTSUKORERI
IPC: H03M1/66
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a high-speed processable secondary digital/analog converter(DACQ) which does not increase current consumption but rather decreases current consumption. SOLUTION: A DACQ composed of a pair of serially connected 1st and 2nd linear converter (DAC) has direct coupling between the output node of 1st DAC 1 and the R-2R type resistor circuit network of 2nd DAC 2, corresponding to the LSB step of R-2R type resistor circuit. A high impedance node, especially the input node of 2nd DAC is appropriately removed from a current path, so as to significantly reduce the problem of comparatively long settling time at the high impedance node (having a related originally large parasitic capacitance). The circuit is markedly simplified by the special architecture of this DACQ.

Filed: 1978-11-21
Abstract: PURPOSE: To make easy the freeze photographing operation using a self-timer by storing the presence or absence of the freeze signal and controlling a photometric value storage memory according to the presence or absence signal.  
     CONSTITUTION: When a freeze switch is operated, a freeze signal is generated from a freeze signal circuit 14 and "freeze presence" is stored in a memory means 11. When a selftimer is set and a shutter release button is pushed, the storage content of the freeze signal presence of the means 11 is read out according to the release signal and a switch means 2 is turned OFF by way of a gate 10, thus the content of a photometric value storage memory 3 is fixed at the provious main subject photometric value. Hence, at the freeze photographing by the self-timer of a changed camera angle, exposure is controlled according to the previous photometric value evne if the mirror is kicked up by way or a delay circuit 21 and release control circuit 22 after the preset timer time. As a result of this, the freeze photographing using the self-timer may be accomplished by the simple operation of changing the camera angle by operating the release switch after the photometry.

Title: Semiconductor device
Inventor: SUMI YUKINORI
IPC: H01L21/60
Filed: 1986-06-23
Abstract: PURPOSE:To prevent a chip from cracking by opening a hole at the end of a lead, and alleviating a mechanical stress to be applied to the lead with a structure that a bump is buried in the hole. CONSTITUTION:Leads 21 are formed by Sn-plating 21b on Cu leads 21a, and a hole 22 is opened at the end. The size of the hole 22 is slightly smaller than the diameter of a bump 14. Since the bump 14 made of gold (Au) is formed in the shape shown in the drawing in the hole 22 by bonding, a mechanical stress applied to the lead 21 is not applied to a silicon substrate 11 as it is to prevent the substrate from cracking. Since the diameter of the bump 14 is larger than that of the hole 22, the Au of the bump 14 is completely buried in the hole 22, thereby completely connecting the leads 21 with the bump 14 and hence the electrode of the chip.
