Title: Manufacture of semiconductor device
Inventor: TAKAYAMA MICHIO
IPC: H01L29/417
Filed: 1984-04-17
Abstract: PURPOSE:To reduce the element area by forming a high-resistant region between a gate region and a source region in the depth direction of a substrate by a method wherein an SIT is constructed by providing the gate region and the source region with a stepwise difference by self-alignment process. CONSTITUTION:An n-epitaxial layer 12 of the gate-forming region is dug in by anisotropic etching. Next, the whole surface is coated with an oxide film by the CVD method; further, the CVD oxide film allowed to coat is removed by anisotropic etching. This process enables only side wall of the n-epitaxial layer previously dug in steeply to be coated with a CVD oxide film 16. Then, a p type impurity is doped from the surface by p type impurity diffusion source 17 or ion implantation. Thereby, the gate region 18 is formed by self-alignment process, and the high-resistant layer between the gate region and the source region of the SIT is provided in the depth direction of the substrate.

Abstract: PURPOSE:To attain the setting of a non-overlap time with high accuracy not affected by variation by allowing a sequence control circuit to perform alternatively charging/discharging of a capacitor charged or discharge by a constant current. CONSTITUTION:When a voltage V1 reaches a logic threshold voltage of an inverter circuit (IV) 1 by the charging to a capacitor C1, an output signal H of the sequence control circuit RC goes from a low level to a high level by its output signal A to switch an output signal B being the result of charging to a capacitor C2 from a high level to a low level.

Abstract: PURPOSE:To obtain a compact high-voltage power unit by adding a surface potential detecting part into said power unit to detect and calculate the surface potential of a photosensitive drum or a sheet. CONSTITUTION:When the potentials of electrodes 51 and 52 are equal to the potential of the surface to be measured, the AC modulation output is equal to 0 and the output voltage of a high voltage generator 62 is also equal to the potential of said surface.

The part 1 contains a reference voltage source, an error amplifier, a V/f converter, etc., which are not shown in the diagram and produces a pulse signal having a frequency corresponding to the error between the detection voltage supplied from the generator 62 and the reference voltage. Then the high-voltage AC output is produced at the secondary winding of a transformer 3 in response to the load state as well as the frequency of said pulse signal according to the ON/OFF states of a switching element 2 consisting of a transistor, etc.

Title: Production of rough shape billet by forging
Inventor: WATANABE KAZUO
IPC: B21J5/00
Filed: 1979-06-18
Abstract: PURPOSE: To form the rough shape billet section being uniform over the lengthwise direction of material by compressing the portion which has been compressed in a nonsteady part at the previous forging compression operation in the steady part in the next forging compression operation and repeating this.  
     CONSTITUTION: The forging tool has such a nonsteady part where the rolling reduction becomes gradually smaller in both compression and width directions at the lengthwise end [range of a distance (n) in the lengthwise direction]. Because of the provision of this nonsteady part, the boundary part in the material after forging becomes smooth transistor deformation part and at the time when the next step forging is to be done, this boundary part is applied with the smooth screw-down from the unforged part toward the already forged part, as a result of which the rubbing down of the metal is prevented and the stepping after the completion of the forging is virtually eliminated. By the above tool, the forging compression is repeatedly progressed in the lengthwise direction of the metal material of a square section, whereby the rough shape billet having a recess at the central part in the width direction is produced.

Title: Clock selection system for decentralized type processing unit
Inventor: KIYOTA KAZUNARI
Filed: 1985-04-12
Abstract: PURPOSE:To improve the reliability of a system without using a highly accurace clock oscillator and an extraction circuit by changing over a clock signal from a clock oscillator into a transmitted clock signal when the clock oscillator of a data processing section is faulty to actuate a transmission circuit of the processing section. CONSTITUTION:If an interruption fault takes place in the internal clock signal from the clock oscillator 13, an internal clock interruption detecting circuit 15 detects it and outputs it to a clock selection control circuit 17. When a switch 18 is closed and a selector 14 selects the internal clock signal, a control circuit 17 discriminates that the same clock signal as the setting value of the switch 18 is in the interruption fault. When the internal clock interruption signal is inputted, it is discriminated to output a clock switching signal to the selector 14 and confirms that no clock interruption signal is inputted from an extraction clock interruption detection circuit 16. When an interruption fault takes place in the reception clock signal from a extraction circuit 10, the selection control circuit 17 discriminates it as an interruption fault of other clock system than the setting by the switch 18 and outputs no changeover signal.

Filed: 1982-05-07
Abstract: PURPOSE:To prevent a malfunction for an automatic focusing system of an image pickup device, by defining the maximum point of a video signal as a focal point to detect a shift of the focal point. CONSTITUTION:A part of the light made incident to an image pickup lens 102 is separated, and a lens 107 is shifted to vary the out-of-focus degree. In response to the shift degree A of the lens 107, a signal B having its apex at a focused point is produced at the output of a wave detector 111. Then the synchronous wave detection is carried out with the signal B and a reference signal C for synchronous wave detection. Thus a signal D is obtained. This signal D is smoothed to obtain an error signal E to actuate a motor 113. As a result, the lens 102 is moved and the motor 113 stops at the point of a synchronous wave detecting output D' and an error signal E' respectively. In this case, the wave detection output is turned into a signal B'. Therefore, if a main image pickup element 105 is focused at the position of the signal B', an interlocking action is secured with an automatic focusing device of a closed loop.
