Title: Screw compressor
Inventor: HIDA TAKESHI
IPC: F04C29/12
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce noise and vibration and improve oil separating efficiency in discharge gas by fixing a relatively small diameter pipe to a discharge pas sage of a discharge cover in a state of one end being inserted in the space of the discharge passage, and opening the other end of the pipe into a discharge chamber. SOLUTION: When a male rotor 6 and a female rotor are rotated by a motor 7, low pressure refrigerant gas taken in from an intake port 8 passes a gas passage between the motor 7 and a casing 1 to cool the motor 7 and then is taken into the meshed tooth surfaces of the male and female rotors and a compression chamber in the casing from an intake port 9. After being compressed, the refrigerant gas is led to a discharge passage 15 through a discharge port 17 formed at a discharge cover 3 and discharged into a discharge chamber 4 through a pipe 20. In this case, the pipe 20 is inserted in the discharge passage 15 only by the length corresponding to 1/4 of wavelength of sound wave. The crest of sound wave and the trough of sound wave reflected by a shielding plate 19 interfere with each other to reduce amplitude of pulsation so as to reduce noise and vibration.

Abstract: PURPOSE:To make the constitution of a magnetic disk device simple and compact by composing a magnetic head positioning mechanism of parallel supporting springs. CONSTITUTION:A magnetic head 3 is held through a head suspension 4 to movable ends 5 of the parallel supporting springs. Fixed ends 7 and the movable ends 5 of the parallel supporting springs are engaged by two parallel supporting springs 6 and permanent magnets 8 are fixed at the movable ends 5 and constitute a magnetic movable type linear actuator together with driving coils 9 arranged while being faced each other. Since a prescribed control current flows to the coils 9, driving force is generated in the permanent magnets 8 and the movable ends 5 are moved only with a prescribed amount. The, the head 3 is moved and set at the prescribed position of a disk 1 through the suspension 4. Thus, since a serial arrangement for the magnetic head positioning mechanism such as head 3 - suspension 4 - movable ends 5 - springs 6 - fixed ends 7 is geometrically turned at the movable ends 5, a plane space can be reduced.

Title: Liquid treating device and method thereof
Inventor: MATSUYAMA YUJI
IPC: G03F7/30
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a liquid treating device hardly generating pull-back phenomenon after the discharge port of a feed nozzle leaves the surface of a substrate by scanning the feed nozzle horizontally to the horizontally held substrate to supply a treating liquid, for example, a developer. SOLUTION: A liquid removing ring formed from a material having larger adhesion to the treating liquid than that to the back surface side of a wafer is provided to surround the substrate horizontally held with a chuck with a small gap. The feed nozzle is moved from one end side to another end side while supplying the treating liquid and the discharge port of the feed nozzle is made close to the top part of the liquid removing ring in the vicinity of another end side of the substrate. Because the treating liquid, through which the discharge port of the feed nozzle and the surface of the substrate are connected to each other by the surface tension, is made flow to the liquid removing ring side to disconnect at this time, excess treating liquid is suppressed to be returned to the surface of the substrate.

Title: Cutting method using wire saw, cutting machine and wire saw
Inventor: HIRANO HISASHI
IPC: B24B27/06
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent the movement of wire and improve further accuracy and efficiency of a wire saw by mounting the wire saw moving wire arranged side by side and cutting a work on a reciprocating frame and performing cutting. SOLUTION: Because a pulley 11 rotates via a shaft 10 when a motor 9 is started, a rotating plate 4 rotates in the direction of an arrow 44 via a shaft 7. Because a crank rod 3 reciprocates in the direction of an arrow 45 or 46 according to this rotation, a frame 2 reciprocates. For instance, when the frame 2 moves in the direction of an arrow 46, wire 13 moves in the direction of an arrow 48. On the contrary, when the frame 2 moves in the direction of the arrow 45, wire 13 moves in the direction of an arrow 47. Therefore, because the reciprocating direction of the frame 2 and the moving direction of wire 13 are always made the same direction, relative speed of a work 50 and wire 13 are doubled, cutting efficiency is improved and cutting accuracy becomes excellent. A wire saw 55 can be miniaturized and cost can be reduced.

Title: Resin composite type vibration-proof steel plate with favorable arc-weldability
Inventor: SHINOZAKI MASATOSHI
IPC: B32B15/08
Filed: 1987-11-11
Abstract: PURPOSE:To obtain a resin composite type vibration-proof steel plate with excellent arc-weldability, by incorporating a ferrophosphorus compound at the interface between a zinc-containing coated steel plate and a resin layer and/or in the resin, in a specified amount based on the resin. CONSTITUTION:A resin composite type vibration-proof steel plate comprises a resin layer sandwiched between surface-treated steel plates provided with a zinc-containing coating on at least one side thereof, with a ferrophosphorus compound incorporated at the interface between the steel plate and the resin layer and/or in the resin, in an amount of 0.5-50wt.% based on the resin. The ferrophosphorus compound preferably has a phosphorus content of 15-55wt.%. The ferrophosphorus compound reacts with zinc and molten iron under the heat of arc welding to form a phosphorus-zinc-iron compound, which is a ternary compound having a high melting point and a high boiling point, so that generation of pits or blowholes due to evaporation of zinc can be prevented. If the amount of the ferrophosphorus compound is less than 0.5wt.% based on the resin, the evaporated zinc can not be converted into the ternary compound to such an extent as to enhance the weldability, whereas if the amount is more than 50wt.%, vibration-proofing performance is poor.
