Title: Aligning apparatus for molded motor shaft
Inventor: UEDA OSAMU
IPC: H02K15/16
Filed: 1980-02-29
Abstract: PURPOSE:To prevent cracks and coil disconnections while aligning a molded resign frame motor shaft by a method wherein the aligning is performed by applying vibration to bearing brackets by means of a shaft aligning member. CONSTITUTION:In an electric motor with the stator iron core 2 and stator winding 3 resin-molded together to form the casing 4, the shaft aligning member 13 is placed lengthwise in contact with the bracket 5. Vibration is then applied to the shaft aligning member 13 by such a vibrating means 14 as a pneumatic power hammer to effect fine alignment between the rotor 9 and stator 1. This keeps the molded casing 4 free of cracks or stator winding 3 discontinuity because the molded layers are not directly exposed to vibration.

Inventor: YO SEKIHIN
IPC: B22F9/04
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To obtain low-cost reproduced W raw material powder from W alloy scrap. SOLUTION: W alloy scrap is oxidized in an oxidizing atmosphere heated at >=600 deg.C and is thereafter subjected to primary pulverization to obtain oxidized coarse powder.

Abstract: PURPOSE:To prevent a printer from entering an error state and prolong the life of a scanner by starting the scanner when the rotation of a photosensitive drum is started, driving the scanner up to a specific rotating speed during the preliminary rotation of the drum, and stopping the rotation of the scanner synchronizing with the photosensitive drum. CONSTITUTION:The rotation of the scanner 4 is started together with the drum 1 when a drum start signal is inputted to a controller 6 and stopped together with the drum 1 when a drum stop signal is inputted. Consequently, the life of the scanner is prolonged. The controller 6 judges whether the scanner 4 attains to the specific rotating speed or not after preliminary rotation time set in the internal timer 7, and extends the preliminary rotation time of the drum 1 until the scanner 4 attains to the specific rotating speed unless the scanner is at the specific rotating speed. Consequently, the printer is prevented from entering an error state.

Abstract: PURPOSE:To reduce a load on a satellite line control station and to improve the completion ratio of a satellite system, by measuring the completion ratio of a call which requests a satellite line, and preventing the inflow of an invalid call to the satellite system or an incoming gate exchange from being generated by closing the line of a gate exchange on a call issuing side, or changing the classification of the line. CONSTITUTION:Each of the gate exchanges 1 and 2 calculates the completion ratio based on the total number of calls and the total number of response calls of a satellite system traffic file 14 periodically, and when the completion ratio is smaller than a set value, closes an output side line so as to match to the completion ratio, or changes the line classification of a direction classified line file 15 to input only. At this time, it is not required to rewrite the gate exchange file 20 of the satellite line control station 5. Also, the completion ratio is calculated based on the total number of calls and the total number of response calls at every incoming gate exchange in an outgoing gate exchange, and when the completion ratio is smaller than the set value, busy display is set at every incoming gate exchange. As a result, when the completion ratio exceeds an on-going value, the autonomous operation of a system can be guaranteed by returning a state to an initialized state.

Title: Ni-base alloy powder for forming amorphous sprayed deposit excellent in corrosion resistance
Inventor: TAKIZAWA YOSHIO
IPC: C22C45/04
Filed: 1988-02-08
Abstract: PURPOSE:To improve corrosion resistance by providing an alloy composition in which specific amounts of Mo and P are incorporated to Ni to an Ni-base alloy powder for forming amorphous sprayed deposit. CONSTITUTION:This Ni-base alloy powder has a composition consisting of, by atom, 10-30% Mo, 15-25% P, and the balance Ni and containing, if necessary, 1-8% B and/or Si. This powder can be produced by forming the molten alloy with the above composition into a powder by a high-pressure water atomizing method and then subjecting this powder to drying and grading. When this powder is used as a thermal spraying powder, an amorphous sprayed deposit excellent in corrosion resistance can be obtained. In the above composition, when Mo content is less than 10%, the required superior corrosion resistance cannot be obtained and, when it exceeds 30%, the melting temp. of the powder is elevated and many defects, such as bores,occur in the sprayed deposit, and further, making amorphous is inhibited and corrosion resistance is deteriorated. When P content is beyond the above range, making amorphous is inhibited. When B and Si contents are less than 1%, the required improvement in the effect of making amorphous cannot be performed and, when they exceed 8%, the action of making amorphous is deteriorated.
