Title: Switching power supply
Inventor: OTAKA TERUAKI
IPC: H02M3/28
Filed: 1987-02-06
Abstract: PURPOSE:To start stably by providing a starting control circuit pulsing an input voltage and a circuit detecting a valley voltage of said input voltage and by causing an apparatus to perform a switching operation from a point of time of detection of said valley voltage. CONSTITUTION:In a switching power supply, the input side of a rectifier bridge 2 is connected with both ends of a commercial power supply 1 and the primary winding 8 and switching element 7 of a transformer are connected with the output side of said rectifier bridge 2. Then, a control circuit 7 is connected with said element 7 and a valley voltage detection circuit 4 detecting a valley of output pulsating voltage of said bridge 2, with said control circuit. Said both circuits 4-5 are supplied with electricity by an auxiliary power circuit and provided with a starting control circuit 3. Thus, when an auxiliary power voltage attains a level at which the switching element 7 can be operated safely, and a valley voltage detection command is given from the valley voltage detection circuit 4, switching is started. As a result, an excessive rush current is prevented from flowing through the switching element 7.

IPC: H01L21/321
Filed: 1991-02-20
Abstract: PURPOSE:To prevent aluminum side etching by coating a wafer with a base film under the condition that the edge of the aluminum of the wiring film is not exposed by covering the edge of the wiring film with a protecting film so as not to expose the edge of the wiring film in the peripheral area of the wafer. CONSTITUTION:An aluminum wiring film 3 is patterned on an insulating film 2 provided on the surface of the semiconductor area of a wafer 1. The wiring film 3 in a peripheral area PZ does not reach the periphery 1a of the wafer 1. Then the wafer 1 is coated with the protecting film 4 on the whole plane. At that time, the wiring film 3 is patterned in the position aloof from a periphery 1a, and the edge is always covered with the protecting film 4. The whole plane of the wafer 1 is coated with a bottom base film 5 and a top base film 6. The top base film 6 is etched leaving the top of each window 4a of the protecting film 4 in a chip area. Since the aluminum of the wiring film 3 is completely covered with the protecting film 4 and the bottom base film 5, side etching is prevented.

Title: Heat treatment of thin strip of amorphous magnetic alloy for magnetostrictive delay wire
Inventor: MAKINO YOSHIMI
IPC: C21D8/12
Filed: 1981-02-23
Abstract: PURPOSE: To produce a magnetostrictive delay wire having uniform characteristics by heat-treating a thin strip consisting of an amorphous magnetic alloy at temps. lower than the crystallization temp. of the amorphous magnetic alloy while holding the same in the state in which tension is acted upon the same.  
     CONSTITUTION: An amorphous alloy ribbon 1 is taken up from a supply reel 2 via a kiln 4 on a take-up reel 3. At this time, tension to the extent of permitting holding of the ribbon 1 substantially linearly is acted upon said ribbon, wherein the tension of about ≤35kg/mm 2  is sufficient. The treating temp. in the kiln 4 is required to be maintained at the temp. lower than the crystallization temp. because the amorphous alloy 1 does not crystallize. The heat treating time is determined by the correlation with treating temps. The cooling may be natural air cooling, but in general it is accomplished at about 25°C/sec. The magnetostrictive constant of the magnetostrictive material is preferably negative.

IPC: H04N5/44
Filed: 1983-02-18
Abstract: PURPOSE:To use efficiently a display section by using the display section for display of channel selecting position at the operation of channel selection in common use for display of a tuning voltage setting value at the operation of channel selection setting. CONSTITUTION:In designating, e.g., the channel 5 from a key switch input section 11 at the channel selection, the channel selecting position ''5'' is displayed on the display section 12, a tuning voltage setting data to select the channel 5 is read from a tuning data storage section 16, converted and outputted into a tuning control voltage by a D/A converting section 13.

Title: Planet roller speed change gear
Inventor: FUKUNAGA TOKIO
IPC: F16H13/14
Filed: 1981-02-23
Abstract: PURPOSE:To make it possible to produce a prescribed contact pressure with a small external force by arranging the outer circumferential surface of a sun roller and a planet roller and the inner circumferential surface of an outer ring in a conical form. CONSTITUTION:Transmission torque produced in an input shaft 1 is transmitted to a sun roller 3 through action of cam rings 3a, 7 making contact with each other on its slope 8a or 8b along with the generation of axial force proportional to said torque. Since the outer circumferences of the sun roller 3 and the planet roller 4 and the inner circumference of an outer ring 5 are formed into conical shapes having small apex angles, large contact pressure is produced in proportion to the tansmission torque between the rollers by the axial force produced on the cam rings 3a, 7 allowing the rotation to be transmitted via a carrier 6 to an output shaft 2. Still more, since there is no sliding between the sun roller 3 and the planet roller 4 and between the planet roller 4 and the outer ring 5 to cause pure rolling contact, the transmission efficiency is improved.

IPC: H04L7/00
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To maintain time division multiple access(TDMA) timing even when a recessed clock is stopped and to reduce power consumption. SOLUTION: A receiver is provided with a timing control section 9 that selects a clock given to a system timing generating section 10. A recovered clock (PLLCLK) outputted from a recovery clock generating section 5 is given to the system timing generating section 10, which generates a system timing during the reception. The timing control section 9 detects a phase difference between a low frequency clock outputted from a low frequency oscillator 6 and the reversed clock before the end of reception to obtain a timing to preset the recovered clock and selects the low frequency clock for the system timing generating section 10. Then the recovered clock generating section 5 is stopped before the preset timing. At the preset timing, the recovered clock generating section 5 is started to select the recovered clock for the system timing generating section 10.

Filed: 1981-02-25
Abstract: PURPOSE:To perform continuous sputtering with good productivity in the stage of forming a hard film on the surface of a metallic material by a sputtering method by passing a material to be treated successively through a pretreatment chamber, a sputtering chamber and a post-treatment chamber. CONSTITUTION:A material 9 to be treated such as cylinder, roll or the like is placed on a carriage 10, and is put into a posttreatment chamber 19. After gaseous Ar is introduced therein, the inside of the chamber is evacuated to a high degree of vacuum. With the material 9 as cathode, high frequency voltage is applied between said material and stainless steel anode 20, then the residual Ar in the atmosphere charges positive, and collides against the material 9 which is the cathode, thereby etching the surface shallow and roughening the surface. Next, the material is shifted into a sputtering chamber 22, where the material 9 is placed near a hard target 23 of Cr, TiN, TiC, etc., and with the target 23 as negative and the material 9 as positive, the material is subjected to a sputtering treatment, whereby the hard material of the target is stuck on the surface of the material 9. Next, the material is put into a post-treatment chamber 24, where the pressure is raised to the atmospheric pressure, after which the material is removed to the outside. If necessary, the surface may be buffed with a polisher 26.
