Title: Dc power supply device
Inventor: KANEDA YAKICHI
IPC: G05F1/563
Filed: 1982-01-30
Abstract: PURPOSE:To keep the power consumption of a variable control element minimum to  enhance the efficiency of a DC power supply device, by providing a means which controls the voltage from an unstabilized power source, which is applied to the series  impedance variable control element, to a required minimum value. CONSTITUTION:A series variable control element 1 is inserted between an unstabilized  power source 2 and a load 3, and an output voltage A of the control element 1 and a  reference voltage B from a reference voltage circuit 5 are compared with each other  in the first differential amplifying circuit 4. The first control voltage C due to the  result of this comparison is applied to the control voltage input part of the control  element 1. The impedance of the control element 1 which supplies a constant voltage  to the load 3 is controlled variably in response to the control voltage C, and the output  voltage of the output side of the control element 1 is made constant. The output voltage A of the control element 1 and the control voltage C are compared with each other  in the second differential amplifying circuit 6, and the second control voltage D due  to the result of this comparison is applied to the power source 2, thus keeping the  power consumption of the control element 1 minimum to enhance the efficiency of the  power supply device.

Title: Cathode for electron beam welder
Inventor: KATSURADA SHIGEO
IPC: H01J23/06
Filed: 1987-01-26
Abstract: PURPOSE:To make an electron beam characteristic not to be changed by providing a recess in advance on the electron radiation surface of a cathode for an electron beam welder. CONSTITUTION:A cathode end face to be affected by ion sputtering is excluded from an electron radiation surface. That is, since a recess 7 is provided in the center of the end face of a rod-shaped cathode 10, a positive ion flow 5 enters the recess 7 to collide with the bottom of the recess 7. Accordingly, a crater 6 due to the ion sputtering is generated only on the bottom of the recess 7. When welding conditions on a substance to be welded are set up on an electron radiation surface 1a excluding the recess 7, ion collision occurs inside the recess 7 so that the electron radiation surface 1a does not change and an electron beam characteristic does not change. It is thus possible to obtain a cathode for an electron beam welder, which fixes a change of an electron beam characteristic due to wear and tear of a cathode radiation surface by ion sputtering for a fixed term.

Title: Preparation of semiconductor device
Inventor: SASAKI NOBUO
IPC: H01L21/302
Filed: 1980-02-07
Abstract: PURPOSE:To form a tapered window, by forming a high concentration region on a PSG (phosphosilicate glass) film, opening a mouth thereon and applying a heat- treatment thereto. CONSTITUTION:When P ions are implanted to the PSG 2 coated with resist-mask 3, these are also implanted in the lateral direction. By means of a plasma etching in CF4 gas, a vertical window S can be formed. By removing the mask 3 and applying heat-treatment in the N2 at the temperature of 950 deg.C, the portion with high concentration of P is softened so that the peripheral part with a gentle inclination is formed. The softening temperature depends upon the amount of implanted P ions. With such an arrangement, the disconnection of wiring can be prevented and a semiconductor device with improved properties can be obtained, without exposing the formed gate oxidized film to such a high temperature as 950 deg.C.

Filed: 1984-01-31
Abstract: PURPOSE:To reduce the load of a programmer by using a jump instruction having the unlimited length processing conditions with no label showing a destinated jumping destination and eliminating the notice for the relation between the jump instruction and the jumping destination. CONSTITUTION:Instructions 30-32 shown by graphic elements indicate the processing conditions of a jump instruction 33. The instruction 30 makes a CPU detect that the relays shown by operands 301-303 are all set ON. An OR instruction 32 makes the CPU detect that one or more of relays shown by operands 401-403 are set ON. While an AND instruction 31 obtains an AND of execution results of front and back logical arithmetic instructions. Thus it is possible to write the unlimited length processing instruction before a jump instruction in such a flow chart type graphic language.
