Patent JP-S6427311-A (JP)
Title: Semiconductor circuit
Inventor: HONMA NORIYUKI
IPC: H01L21/8249
Filed: 1988-06-20
Abstract: PURPOSE:To attain low power consumption and high speed through the combination of CMOS and bipolar circuits by allowing a CMOS circuit to drive a light capacitive load and allowing a bipolar/CMOS composite circuit to drive a heavy capacitive load. CONSTITUTION:The bipolar/CMOS composite buffer circuit 22 is added to the CMOS gate circuit 21. Through the constitution above, when the load capacitance CL is small as nearly as 0.1pF, a sufficiently high speed is attained generally by the circuit 21 only and the addition of the circuit 22 causes the response of load driving to be made slow instead. When the load capacitance CL becomes larger, for example, as nearly as 1pF, the response by the circuit 21 slows down because of insufficient driving capability. That is, the operating speed of the CMOS circuit and that of the bipolar/CMOS circuit are reversed themselves depending on the load capacitance. In using the composite circuit of bipolar/CMOS depending on the situation in such a way, the delay time of the entire circuit is reduced.

Filed: 1980-10-27
Abstract: PURPOSE:To reduce the load voltage at interruption and to decrease the dielectric strength at load side, by performing off-operation of a plurality of thyristor switch circuits in series connection when a load is interrupted, through shifting timewise. CONSTITUTION:A DC power supply 1 is constituted with a load branching circuit where a main switch circuit 3, loads 21-2n in parallel with the circuit 3, a series circuit of auxiliary switch circuits 41-4n in series. In this case, a load opening signal SCB turns off the main switch circuit 3 by giving a trigger current of an axuiliary thyristor 32 to the circuit 3 from a control circuit 7 via gate trigger circuit 5  and 61-6n. In this case, a load voltage is the sum of a voltage eC1 of a commutating capacitor 33 and a power supply voltage EC. Next, after the voltage eC1 is discharged through the interruption of the circuit 3, for example, the auxiliary switch circuit 41 turns off to make the load voltage to be the sum of the voltage eC2 and the EC.

Title: Inspection method for alignment of photo-mask
Inventor: WATANABE KAZUYA
IPC: G03F1/84
Filed: 1985-07-09
Abstract: PURPOSE:To improve the precision of the state of superposition by forming checking patterns having the same shape to each of a plurality of photo-masks, superposing these patterns and deciding the precision of alignment. CONSTITUTION:The same checking patterns 12 are shaped severally to masks 11a-11c. The shapes of the images 13 of the checking patterns formed by using respective mask are decided, and the accuracy of superposition of these masks 11a-11c is inspected. The images 13 are inspected in such a manner that beams 10 shown in the arrow are projected and resist patterns are developed and measured. The shapes of the images 13 coincide with the shapes of the patterns 12 when all masks are relatively aligned correctly in the inspection method, but the shapes of the images 13 are made different from those of the patterns 12 when the masks are not relatively aligned precisely. Accordingly, the accuracy of the relative alignment of all masks can be decided by judging the shapes of the images 13.

Title: Manufacture of thermoplastic resin film
Inventor: KONISHI TOMOAKI
IPC: B05D7/04
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To obtain a stable film formation by coating at least one side surface of an unoriented or uniaxially oriented film with a coating agent, coating an area not coated with the agent with a liquid, setting a temperature unevenness of the film in a lateral direction except its edge to a specific temperature or lower, and orienting the film in the lateral direction. SOLUTION: A film itself is heated to a temperature necessary for orienting up to immediately before the orientation. At this time, a solvent of a coating agent A is evaporated, and the film temperature of an area coated with the agent A is scarcely raised according to its evaporating latent heat. Since an evaporating latent heat of a liquid B is generated by coating an area not coated with the agent A with the liquid B, a temperature rise of the film of this area is suppressed. As a result, a film temperature differences between both the areas is suppressed to a low value. A coating amount of the liquid B may be decided so that the temperature difference falls within 25 deg.C.

Filed: 1983-08-22
Abstract: PURPOSE:To generate ultrasonic waves in a metal cylinder body efficiently, by winding a flat coil, which is formed in a vortex shape by using a conductor wire, along the outer surface of a tube shaped or rod shaped metal cylinder body, and connecting a means, which makes a current flow through the coil instantaneously, to the body. CONSTITUTION:A capacitor 4 is charged by a power source 4 and a rectifier 6. When a switch 3 is closed, a discharge current instantaneously flows from the charged capacitor 4, and a magnetic field is generated in the direction of the diameter of a metal cylinder body 2, around which a coil 1 is wound. In the case the material of the metal cylinder body 2 is ferromagnetic material such as iron, the outer part of the metal cylinder body 2 is magnetized by the magnetic field. An attracting force acts between said part and the magnetic force caused by the coil 1. Thus the metal cylinder body 2 is deformed in the direction of the radius. Along with said deformation the metal cylinder body 2 is deformed also in the direction of the length, and pulse shaped ultrasonic waves are generated in the metal cylinder body 2.
