Title: Gear device
Inventor: DOBASHI TAKAHIRO
IPC: F16H1/00
Filed: 1988-02-29
Abstract: PURPOSE:To improve positioning accuracy with low noise and without wear or seizure by forming one of gear pair, facing each other, of oxide superconductive material, and forming the other gear facing the same of a magnetic material. CONSTITUTION:One gear is formed of an oxide superconductive material 1, and the other gear facing the same is made of a magnetic material, and neighboring teeth are formed of magnets 2 with different polarities. Magnetic force lines 3 are generated between teeth of the gear on the magnets 2 side, but the lines are bent by the Missner effect of the oxide superconductive material 1. As a result, resilient forces act between the oxide superconductive material 1 and the magnet 2, and both stand sill on the position at which the repellent forces get to balance. Hereupon, when the oxide superconductive material 1 is moved in the direction shown by arrow marks, a gap alpha1 becomes smaller and a gap alpha2 becomes larger, and as a result, the repellent force acting on the gap alpha1 gets stronger, while the repellent force acting on gap alpha2 gets weaker. Consequently, the magnet 2 moves by the reception of force in the arrow mark direction, and movement is transmitted without any contact between both gears.

Title: Tester for differential gear
Inventor: BABA FUMIHIKO
IPC: G01M13/02
Filed: 1979-04-13
Abstract: PURPOSE:To make possible highly precise measurement of torque even if the speed difference between the absorbers is small by controlling the speed of the driving body, the torque of each absorber, and the speed difference between the absorbers. CONSTITUTION:The characteristic of the torque difference DELTAT to the revolution- speed difference DELTAN between each output shaft of a differential gear 1 can be usually measured when the revolution-speed difference DELTAN between absorbers 4A and 4B is large to some degree by controlling the speed of the absorbers 4A and 4B. However, the measurement of DELTAT1 is difficult when the revolution-speed difference DELTAN1 is smaller than a fixed value, exceeding the speed-control precision. The torque characteristic of DELTAT1 can be measured by constant-speed control of an electric motor 2, current or torque control of dynamometers 4A and 4B, installation of speed difference-setting device 10 for obtaining optional revolution-difference, and proportional control of the revolution difference. Thus, the torque characteristic can be measured highly precisely even if the speed difference between the absorbers is small.

Abstract: PURPOSE:To prevent the generation of the vibration of a chain caused by the intake of the air immediately after a start by opening one end of an orifice passage in an oil sump chamber of the tip of a plunger, ans eccentrically arranging a working chamber opening end and the oil sump chamber opening end respectively upper and lower of the center line of the plunger. CONSTITUTION:Immediately after an engine start, even if a backing plunger 36 projects suddenly, the lubricating oil in an oil sump chamber 48 is sucked into a working chamber 37 to eliminate the danger that the air is sucked from the outside into the working chamber 37. Especially, an opening end of the oil sump chamber 48 of an orifice passage 52 is positioned in the lower of the oil sump chamber 48 to secure a distance in vertical direction to the oil surface of the oil sump chamber 48, namely, an air exhaust hole 49, and the air intake is prevented more surely. Since the working chamber 37 side opening end of the passage 52 is positioned upper than a center line l of the plunger 36, namely, it is positioned in the more upper part of the working chamber 37, the capacity of the air remaining in the upper part is greatly reduced, and the air exhaust is performed more surely.

Abstract: PURPOSE:To enable semiconductor thin films to be deposited repeatedly without changing the doping concentration in the semiconductor thin films by a method wherein the semiconductor thin films are deposited in the first as well as the repeated processes at the same deposition temperature. CONSTITUTION:A GaAs buffer layer 12, an InGaAlP-n type clad layer 13, an InGaP active layer 14, an InAlP-p type clad layer 15 and a GaAs cap layer 16 in a MOCVD device are deposited on a preprocessed GaAs substrate 11 at the deposition temperature (1) of 700 deg.C. In order to deposit a laser structure, the substrate 11 is etched away taking mesa stripe shape and later a high resistant buried layer 17 (3) is deposited so as to bury the both sides of the stripe, of the substrate 11. The deposition temperature at this time is to be at 700 deg.C similar to that when the double hetero structure (2) is deposited. Through these procedures, the carrier concentration in the layers previously crystal-deposited does not decline even if the crystal deposition is repeated.

Abstract: PURPOSE:To make overall distortion constant independently of the presence of a booster amplifier. CONSTITUTION:An input signal applied to an input section 3 by a prescribed amplification characteristic and the amplified output is sent to a post-stage. When a booster amplifier 7 is present on the posts-stage of the concerned amplifier, changeover switches 4a, 4b are switched so as to allow an attenuator 6 to attenuate the level of the input signal by a prescribed quantity. Since the signal is amplified at a power amplifier 2 at a region where the linear amplification characteristic is more excellent, overall distortion is made constant.
