Title: Controlling system for injection molder
Inventor: KISHI YASUO
IPC: B29C45/64
Filed: 1985-05-22
Abstract: PURPOSE:To prevent a mold from being marred by a method wherein the mold, from which a molded part is ejected lastly, is held at the state that no pressure is applied to the mold and, after that, the remaining molds are open in an injection molder equipped with a plurality of movable mold-clamping mechanisms. CONSTITUTION:Firstly, a mold C, from which a molded part 30 is ejected lastly, is held at the state that no pressure is applied to the mold C by retreating the mold C in the direction indicated with the arrow C by a very small distance (alpha) after the injection of the molded part. Secondly, molds A and B are opened in the directions indicated with the arrows A and B and, after that, the molded part 30 is ejected. Consequently, the molds can be prevented from being marred and worn.

Title: Volume type fluid compressor
Inventor: TOYODA HIROSHI
IPC: F04C18/02
Filed: 1978-09-04
Abstract: PURPOSE: To prevent exhaust fluid from flowing back between a pair of scrolls by setting up a lead valve which blocks a penetrating hole on the exhaust room end on the plate body of the scroll member.  
     CONSTITUTION: The lead valve 32 is opposed to the plate body 251 of the scroll member 25 so as to block the penetrating hole 253 on the exhaust room end 31 and one end of this lead valve is fixed to the plate body 251. This prevents the fluid from flowing back between the scroll members 24 and 25 from the exhaust room 31. This also reduces energy and exhaust pressure losses and controls the variation in gas pressure in the exhaust room 31 on a small scale.

Abstract: PROBLEM TO BE SOLVED: To mount fine components on a board with sufficient strengths and with a high density by using metal material which never causes lead contamination by a method wherein a metal layer whose main component is zinc is formed on the surface of a circuit interconnection metal layer and a metal layer whose main components are tin and zinc is formed on the metal layer. SOLUTION: Circuit interconnection metal layers on a circuit board are wetted with solder material whose main compoennts are tin and zinc to mount electronic components. At that time, zinc-rich layers are provided near the boundary surfaces between the solder material and the circuit interconnection metal layers. The zinc-rich layers may be formed by the deposition from the solder material. For instance, 1st circuit interconnection copper layers 2 are formed on the surface of a board 4 and interconnection copper layers 3 are formed also in the board 4.  Then, solder which is eutectic material containing, for instance, more than 90.9% of tin and 9% of zinc is melted and dropped onto the copper interconnection layers 2 on the surface of the board 4, solder layers 1 which are 3rd metal layers 3 are formed on the surfaces of pads and the solder layers 1 are also formed on the surfaces of the copper interconnection layers 2 on the rear of the board 4.

Title: Clamping circuit
Inventor: TSUCHIYA KEN
IPC: H04N5/18
Filed: 1989-04-27
Abstract: PURPOSE:To perform clamping with high accuracy even when a video signal is a compound video signal or a color difference signal by automatically switching an operation to the one of pulse clamping system by supplying a clamping pulse, and switching it to the one of self-clamping system when no clamping pulse is supplied. CONSTITUTION:When the clamping pulse is inputted to an integration circuit 9 via an input terminal 4, the clamping pulse is outputted supplied to a pulse input terminal 8a from a pulse mode switching circuit 8 as it is, and the ON/ OFF operation of a transistor 7a is performed corresponding to the clamping pulse. Thereby, a clamping operation of pulse clamping system is automatically performed. When no clamping pulse is supplied, no output is issued from the integration circuit 9, and a signal of constant level ('H') is outputted from the pulse mode switching circuit 8, and it is supplied to the emitter terminal of the transistor 7a in a constant current circuit 7, which always turns on the transistor 7a. Therefore, the operation of self-clamping system can be automatically performed.

Title: Semiconductor laser driving circuit
Inventor: KUBOTA SHINJI
IPC: G11B7/125
Filed: 1989-04-27
Abstract: PURPOSE:To reduce a thermal load to a recording film and to prevent the recording film from being broken by bringing an optical output to AC modulation and allowing it to rise, at the time of setting to recording power or erasion power from reproducing power. CONSTITUTION:At the recording time when a recording gate WG is 'H', an analow switch SW4 is selected,and at the reproducing time when the gate WG is 'L', a switch SW5 is selected. Therefore, only at the time of recording, a peak holding circuit 22 detects a peak of a monitor voltage VM and inputs it to a servo-amplifier 4. On the other hand, an AND gate 24 of a recording data control means 23 takes AND of an inversion output of a holding gate HLD and the gate WG and generates a recording set section signal SET. Subsequently, by an AND gate 25, AND to AC modulation data ACDT is taken, and by adding the AC modulation data to regular recording data WDT, recording data WDTT is generated. In such a way, a thermal load to a recording film at the time of setting an optical output is reduced and it is prevented that the recording film is broken and its service life becomes short.

Filed: 1990-04-26
Abstract: PURPOSE:To move a tension pulley smoothly in the vertical direction by furnishing a roller, which rolls in contact with a rail surface, at the side of a framing of a tension pulley device for a rope of a speed governor. CONSTITUTION:A holddown arm 17 is mounted protrusively on a guide rail 16, which is arranged alongside an inclined elevating path 15 so as to guide an elevator cage, and rails 18A, 18B are fixed to the holddown arm 17 and arranged in parallel with the guide rail 16. Rollers 21A, 21B installed on the rail 18A side of a framing 10 and rolling on the surface of the rail 18A are mounted at the side situated nearer that side, where the axis of movement forms an acute angle with the bottom surface of the elevating path, than the axis of movement of the framing 10. The framing 10 moves up and down along the rails 18A, 18B, when the force acting on the rail 18A will be borne by the rollers 21A, 21B. This enables a tension pulley to make vertical motion smoothly even when dust is attached to the rails or when the framing is inclining relative to the rail.

IPC: E02F3/90
Filed: 1993-05-11
Abstract: PURPOSE:To provide a hydraulic system which prevents noise and vibration from producing to enable speed control and is capable of operating a slurry pump at high volumetric efficiency. CONSTITUTION:Ten units of hydraulic pumps 1 to 10 are used, and check valves 101, 201,... 1001 are set in the delivery circuits for the hydraulic pumps 1 to 10. Also unloading relief valves 102, 202, 1002 are set in the delivery circuits for all the hydraulic pumps 1 to 10. The operating speed of a slurry pump is determined by the number of hydraulic pumps to be loaded. When the force- feed pistons 34 and 44 and suction and delivery valves 50 of the slurry pump are started and stopped, the hydraulic pumps 1 to 10 are on-loaded and unloaded one by one at a specified interval. Thus the movement of the suction and delivery valve at its start and end is made smooth. In addition, the operating speed of the slurry pump is adjusted by selecting the number of on-load hydraulic pumps among the hydraulic pumps 1 to 10.

Filed: 1989-04-28
Abstract: PURPOSE:To detect the foreign matter or flaw on an object to be detected with a good S/N ratio by detecting infrared rays generated from the object to be detected by heating or cooling said object. CONSTITUTION:An object 3 to be inspected is arranged for a short time, for example, for 5sec in the vicinity of a heat source 1 set so as to keep predeter mined temp. Thereafter, the object 3 to be inspected is moved to immediately perform observation using an infrared detector.
