Title: High-frequency link converter
Inventor: TANAKA SHIGERU
IPC: H02M5/27
Filed: 1989-02-07
Abstract: PURPOSE:To keep a voltage stable even if power is a single-phase AC or a load is unbalanced, by providing an apparatus with two cycloconverters. CONSTITUTION:A first cycloconverter CC-1 controls a power Pi corresponding to an effective power PL taken by a load apparatus LOAD so that said power Pi is supplied from a single-phase AC power supply SUP, while controlling an input current Is so that a voltage Vd applied to a DC smoothing capacitor Cd connected with the output side terminal of a second cycloconverter CC-2 is kept constant. Said second cycloconverter CC-2 controls a DC current Id so that a voltage applied to a high-frequency capacitor CAP is kept constant, while controlling said DC current Id, when there is a difference between a load current PL and a supply current Pi, so that a power corresponding to said difference is temporarily supplied from said DC smoothing capacitor Cd.

Title: Can centering method in seaming device and can lid used therein
Inventor: MORIMOTO KENJI
IPC: B65D17/00
Filed: 1986-02-12
Abstract: PURPOSE:To correctly perform the fitting of a can to a chuck and to prevent the buckling of the can due to unbalanced load by engaging in contact with the inner wall of a knockout pad, the tab outside part of the can lid and plural beads, while chucking the can lid with the ascent of a turret. CONSTITUTION:A centering is performed by seaming turret 9 and can feeding turret 10 by moving to a lifter 11 the lid 1 of the can C which packs the contents. The centering is performed with the contact engagement of the inner lid 13 of a pad 12, the tab outside parts 21, 22 of the lid 1 and plural beads 41, 51 by descending a knockout pad 12 simultaneously with this. The can C is then led upto the chuck 14 with the pad 12 by ascending it with engaging it with the lid 1 according to the lift of the lifter 11. As a result, a correct centering of the can be performed even in case of a high speed seamer and the can is pinched in the stage of correctly positioning it at the center part of the lifter chuck. The buckling due to the unbalanced load of the can having weak axle load can therefore be prevented.

Abstract: PURPOSE: To secure the display on the surface of device for the date and the conditions of manufacture and others via the symbols.  
     CONSTITUTION: When forming resist pattern 3 on oxide film 2 of Si substrate 1, the display symbol 5 such as the data and conditions of manufacture is formed sumultaneously through etching of film 2. Then resist film 3' and symbol 6 are formed via mask F' after formation of the base layer. After formation of the emitter layer and the diffusion layers of symbol 5 and 6, resist 3" is formed via mask H' with the electrode window drilled to film 2. Then the A evaporation film is coated, and resist 3" is formed via mask J' to then form emitter and base electrode 11 and 10 by etching. At this moment, symbol 9 is formed to the A film. In this way, symbols 5, 6 and 9 are provided in α, β and γ units respectively to obtain combination of α × β x γ in order to display various kinds of contents. This method is highly effective especially for the device featuring a small measurement.

Title: Logic circuit
Inventor: HIRANO YOUJI
IPC: H03K19/086
Filed: 1980-03-04
Abstract: PURPOSE:To enable high-speed operation by connecting a transistor, applied with a constant voltage at its base, in series to the input transistor of a current switching type logic circuit. CONSTITUTION:To collectors of input transistors T1-Tn connected in parallel while their bases are used as input terminals, constant voltage transistor TV connected to a constant voltage source at its base is connected. At this time, fluctuations of VBE of constant voltage transistor TV are nearly equal to those of VBE when input transistors T1-Tn are turned off and on. Therefore, fluctuations of VBE of transistor TV and fluctuations of collector potential of transistors T1-Tn are approximately a half the output logical amplitude and the Miller effect is reduced, so that switching characteristics will be improved.

Title: Wire saw cutting method and device
Inventor: ASAKAWA KEIICHIRO
IPC: B24B27/06
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To cut an ingot into wafers of a desirable shape by avoiding uneven wear of a wire that is liable to cause waviness on the cutting face of the wafers. SOLUTION: A wire is looped spirally round grooved rollers 1 to 3 held parallel one another around an ingot 9. In slicing the ingot 9 with the wire moved in one direction or both directions to which slurry is supplied, the wire let off a reel 6 is given circumferential torsion before reaching the ingot 9. The torsion amount and direction of the wire are controlled depending on the wire moving speed and direction among others. The torsion-given wire rotates circumferentially while cutting the ingot 9 and thus never wears out partly so that its full circumferential area is well used to cut the ingot 9. This method ensures better rectilinearity of the wire to prevent waviness that wafer cutting faces are liable to have.

Title: Data recording system for optical disk device
Inventor: HIROSE YUTAKA
IPC: G11B7/00
Filed: 1988-02-10
Abstract: PURPOSE:To improve recording density without changing the shape of a recording medium or the position of a recording pit by changing the length of the recording pit in >=2 types in correspondence to multivalued data while executing recording. CONSTITUTION:The recording position of recording pits 12 and 13 are changed in correspondence to recording data and the lengths of the recording pits 12 and 13 are caused to correspond to the multi-value data. Namely, the recording pits 12 and 13 are formed on one guide 11 while causing the length in a guide direction slightly different. Accordingly, for crests 21 and 22 of an RF reproducing signal, a width is changed in correspondence to the lengths of the recording pits 12 and 13 and the features of both a spot recording system and a width modulation recording system can be made useful. For example, in the recording of a 2-7 modulating system, the data to be converted to a long code can be made correspondent to the data of the same pattern as the shorter code and the only different length of the pit. Thus,the number of the pits, which are needed to record the same data, can be reduced and the recording density is improved.

Abstract: PURPOSE:To provide a loop type heat transfer device which is easy to handle and easy to install by forming the whole of a loop type container or its specified section with a pipe of a specified plastics or a specified synthetic rubber. CONSTITUTION:All of a loop type container 1 in a loop type small heat pipe or a container 1 of a loop pipe type is formed by a plastic pipe or synthetic rubber pipe. Both ends of the looped pipe are mutually connected by a socket coupling 4 with an adhesive 5, but it is possible to connect by thermal fusion according to the material. When a flexible plastic pipe or flexible synthetic rubber pipe is used it is possible to constitute it as a flexible snaking loop type heat transfer device which can be used very simply. The heat receiving and heat radiating sections 1-H and 1-C are plastic pipes so that their heat conductivity is low and it is difficult to realize a high performance by them, but there is an advantage that the heat loss is the thermal insulation section 1-N is small. Especially by applying an expandable plastic pipe only to the thermal insulation section the heat loss can be further reduced.
