Title: Image forming device
Inventor: NOZAKI TAKESHI
IPC: H04N1/04
Filed: 1989-06-30
Abstract: PURPOSE:To reduce the price and to accelerate image forming operation by rewriting shading correcting data which is stored by a first storing means and is in the main scanning direction when the shading correcting data value at the last line of image information reading by means of a scanning means exceeds the standard. CONSTITUTION:The device is constituted so as to rewrite the shading correcting data, which is stored by the first storing means and is in the main scanning direction, when the value of the shading correcting data in the subscanning direction stored by a second storing means at the last line of the image information reading by the scanning means 15 exceeds the standard. Therefore, since the reliability of the image information during one scanning by the scanning means of a reading part 10 is ensured without using a heater and a temperature control circuit for maintaining the temperature of a fluorescent light nor rewriting the shading correcting data in the main scanning direction for every one scanning, the cost is reduced and the operation time is shortened. Thus, the price is reduced and the image forming operation is accelerated.

Title: Semiconductor integrated circuit
Inventor: URIYA SUSUMU
IPC: H01L21/822
Filed: 1983-09-14
Abstract: PURPOSE:To eliminate an external effect (a phenomenon in which the outside is easy to be etched) in an upper electrode group by surrounding the periphery of the upper electrode group, to which a unit capacitance element group is formed, by a frame-shaped pattern shaped under predetermined conditions. CONSTITUTION:In a semiconductor integrated circuit in which a plurality of unit capacitance elements are collected and predetermined capacitance is obtained, the periphery of upper electrodes 1 for each element is surrounded by a frame-shaped pattern 7. The frame-shaped pattern 7 is formed by the same material as the upper electrode 1 under the same processing conditions as the electrode 1, and shaped at the same interval (a) as a separation distance among each capacitance element. Consequently, an external effect can be eliminated because each electrode pattern can be equalized to an etching effect. Parasitic capacitance with others is minimized by connecting the frame-shaped pattern to a line having low impedance, and the induction of noises can be reduced by a shielding effect.

Title: Constant current circuit
Inventor: FUKUZAWA FUMIHARU
IPC: G05F3/24
Filed: 1988-07-06
Abstract: PURPOSE:To suppress the variation of a current due to the change of the power supply voltage by inserting a pair of 5th and 6th field effect transistors (FETs) of a one-conduction channel or an opposite-conduction channel type having their gates connected to each other between 1st and 2nd FETs and between 3rd and 4th FETs respectively. CONSTITUTION:A pair of N or P channel type insulated gate type FETs IG- FETQ5 and IG-FETQ6 having their gates connected to each other are inserted between the drains of a one-condition (N) channel type IG-FETQ1 and an opposite-conduction (P) channel type IG-FETQ2 and between the drains of an N channel type IG-FETQ4 and a P channel type IG-FETQ3 respectively. In such a constitution, the effective channel length of the IG-FETQ1 has no change in case the power supply voltage is changed. Thus the variation of the DC gain of a constant current circuit is caused only by the variation of the effective channel length of the IG-FETQ3. Then the current variation is avoided. As a result, the change of the current due to the change of the power supply voltage can be suppressed.

Abstract: PURPOSE:To prevent a holder from being broken against tensile stress and a shearing force operating on an axial part between the tool receiving part of a holder and a screw part for fitting at the time of holder clamping by providing a reinforcing means at the axial part. CONSTITUTION:The device 10 is fitted in a fitting hole formed in the cylinder wall of an engine and while the screw part 11b is engaged threadably with the fitting hole by rotating a hexagonal part 11c with a tool, clamping torque operating on the hexagonal part 11c operates on the axial part between the tool receiving part and screw part 11b as the tensile stress and shearing force. A protection resin body 5 charged in the internal space part of the holder 11 is engaged with the holder 11 in the axial direction and circumferential direction by the screw groove of the reinforcing part 12 at the part. The stress operating on the axial part of the holder 11, therefore, operates on the resin body 5 as well and the resin body 5 contributes to the reinforcement for the rupture resistance of the holder 11. Consequently, even when the holder 11 is clamped sufficiently in the fitting hole, the holder 11 is prevented from being broken before that.

Abstract: PURPOSE:To make watt consumption in a solenoid valve abatable by installing the solenoid valve, receiving fuel pressure in a plunger pressure chamber in the closing direction of a return passage, in this return passage side by side. CONSTITUTION:In a plunger pump 20, there is provided with a return passage 26 which interconnects a pressure chamber 25 to a low pressure chamber 23. Then, a solenoid valve 27, receiving fuel pressure in the pressure chamber 25 in the closing direction of the return passage 26, is installed in this passage 26 side by side. Here a drive circuit 34 operates this solenoid valve 27 for closure at the specified fuel injection starting time. At this time, since the high fuel pressure in the pressure chamber 25 acts in the closing direction of the solenoid valve 27, there is good enough small solenoid force for this valve 27, and that, after valve closing, it is kept up in a valve closing state with the high fuel pressure, so that watt consumption is sharply abated.

Abstract: PURPOSE:To improve the performance characteristics of the sections of I<2>L elements by a method wherein two types of I<2>L structures are built with their N-epitaxial layers different in thickness under base regions for the co-existence of high-speed and low-speed sections. CONSTITUTION:An N<-> epitaxial layer 2 is thinner under the base region of a high-speed I<2>L section than under the base region of a low-speed I<2>L section. For example, an N-type epitaxial layer 2 is formed on a high-concentration N-type semiconductor substrate 1 and the portion to mount a high-speed I<2>L section is selectively removed by approximately 1mum. N<+> collar regions 3, base regions 4a and 4b, injector regions 5a and 5b, and collector regions 6a and 6b are formed, and then an aluminum wiring 7 is built. The selective removal of the epitaxial layer 2 is accomplished for example by using the LOCOS method and the oxide film etching method. With the device designed as such, the high-speed section is improved in terms of the minimum delay time for the ensurance of higher-speed operation and the low-speed section is reduced in its power delay time product. In this way, both high-speed and low-speed sections are improved in their performance characteristics.

Title: Automatic gain control circuit
Inventor: KAWAI HISASHI
IPC: H03G3/30
Filed: 1987-07-10
Abstract: PURPOSE:To always obtain a stable output in a prescribed level by providing a first detecting means which detects the output level and a second detecting means which detects the presence or the absence of an input signal and changing the output level from a reference voltage setting means and the frequency characteristic of a two-wave means in accordance with the output from the second detecting means. CONSTITUTION:When a video signal having a normal amplitude is inputted, the reference level of a reference voltage setting circuit 3 is fixed to the first level because an input detecting circuit 6 outputs the high level which indicates the presence of the input signal. When disappearance of the input signal is discriminated, the output of the input detecting circuit 6 goes to the low level and the reference level of the reference voltage setting circuit 3 is changed to the second level. Since the output of an AGC amplifier 1 is suppressed by this change, the noise whose amplification is started on the side of an output terminal 202 is reduced. Thereafter, the frequency band of an LPF 5 is changed and fixed to the second frequency characteristic, and the time constant of operation is shorter. Consequently, this circuit is operated to amplify the signal to a steady level with quick response.

Title: Plate-like member conveying device
Inventor: ITO YASUSUKE
IPC: B66C1/04
Filed: 1994-07-22
Abstract: PURPOSE:To greatly reduce the cost and to make a plate-like member conveying device lightweight and compact by providing such an arrangement that a ball valve element is raised by a suction stream flowing through a cylindrical part in a suction port which does not suck a plate-like member, so as to close a valve seat. CONSTITUTION:A suction box 17 is evacuated so that suction ports which are distributed allower a surface of the box 17 vacuum-suck the entire surface of a plate like member, surely, even though an opening is formed in the plate- like member. Accordingly, an elevator frame 10 is elevated in a condition in which the suction box 17 sucks the plate-like member, and a runner is moved so that plate-like members are surely conveyed one by one. Further, a suction port facing the opening formed in the plate-like member is automatically closed since a ball valve element 35 is raised by a suction stream flowing through a cylindrical part 21a of a sucking cylinder 21 so as to close a valve seat 33, and accordingly, it is possible to prevent a suction stream from being left to flow. Accordingly, even though a vacuum pump or an ejector having a small capacity is used, a necessary vacuum can be held in the suction box 17, thereby it is possible to surely convey the plate-like member.

Title: Multi-branch switch
Inventor: NAKAGAWA KATSUMI
IPC: H03K17/693
Filed: 1981-10-26
Abstract: PURPOSE:To obtain a multi-branch switch which performs the same function as a branch switch which has (mXn) pieces of branch terminals, by forming plural branch switches having a comparatively small number of branch terminals on a thin film conductor. CONSTITUTION:The signals phi1 and phi2 which drive multi-branch switches  SW1-1-SW2-4 have pulses having phases opposite to each other. The signals phi1 and phi2 are stepped down by a frequency stepping-down circuit 100 which drives branch switches SW3-1-SW4-2 of the next stage, to obtain signals phi'1 and phi'2. The electric charge stored in the capacitors C1-1-C1-8 after passing through resistances R1-1-R1-8 is applied to branch terminals B1-B8 of a multi-branch switch. The signals phi1 and phi2 are fed to the switches SW1-1- SW2-4, and the signals phi'1 and phi'2 are fed to the switches SW3-1-SW4-2. Furthermore signals phi''1 and phi''2 are fed to the switches SW5 and SW6. As a result, the electric charge stored in the capacitors C1-1-C1-8 is extracted outside in the form of an output current only while a conductive state is secured between the branch terminals connected to the capacitors C1-1-C1-8 and a main terminal MT.

Abstract: PURPOSE:To execute muting even in a silent part such as intermusic, etc., of a compact disk by controlling an output level of a D/A converter, based on an output of a zero detector for detecting a fact that an input of a digital filter is zero for a prescribed period. CONSTITUTION:The title device is provided with a D/A converter for converting an output of a digital filter to an analog signal, and a level controller for controlling an output level of the D/A converter 2, based on an output 4 of a zero detector for detecting a fact that an input of a digital filter is zero for a prescribed period. That is, by detecting infinity zero of an input of the digital filter 1, and controlling the output level of the D/A converter 2 thereby, an input signal is delayed by the digital filter 1 even when a zero input has been varied to other value than zero, therefore, prior to a variation of the input, a level control of the output of the D/A converter 2 can be executed, and even in a silent part such as intermusic, etc., of a compact disk, muting can be applied.
