IPC: B21K1/76
Filed: 1984-12-10
Abstract: PURPOSE:To obtain the titled universal joint outer ring with good productivity by subjecting to ironing or swaging after repsetting a round bar shaped blank, forming the blank consisting of the cup part enlarging the opening part and a shut and giving the cross groove having a draft on the inner face of the cup part at the same time. CONSTITUTION:A blank material 1 is obtained by extruding forwardly a shaft 2 after making a round bar in a drum shape with upsetting and by extruding backwardly out a cup part 3 simultaneously. The inclination alpha deg. of the cup part 3 and the groove width correction amount beta deg. of the groove part 4 are determined so that the groove part 4 is not made in an under-cut, i.e., in order to give a proper draft to the groove part 4 in the blank material 1 and the correction amount l is decided with taking into consideration the elongation in the axial direction by the ironing or swaging further. Consequently the universal joint outer ring having the cross groove shown by a dotted line is obtd. by performing the swaging by the alpha deg. with performing the ironing or swaging of the outer side of the cup part 3 in the second stage.

Filed: 1990-09-28
Abstract: PURPOSE:To prevent the operation sensitivity of the telephone set from being effected by the operating condition by measuring a time till the operation is implemented after the access of a hand of the operator is sensed by a timer and using a sensitivity change means to adjust the sensitivity of a sensor depending on the difference between the measured data and an object. CONSTITUTION:A control means 1 uses a microcomputer to control a speech circuit or the like. A sensor 2 senses it that a hand of the operator is accessed and outputs a sensing signal. A sensitivity change means 3 sends an output of the sensor 2 to the control means 1 and revises the sensitivity of the sensor 2 by using a count data output from the control means 1. A timer 6 counts the time after the sensor 2 senses the access of the hand of the operator till the operation button 5 or a dial button 4 is depressed. Thus, the sensitivity of the sensor 2 is revised depending on the time counted by the timer 6.

IPC: F04B49/10
Filed: 1994-09-30
Abstract: PURPOSE: To detect whether the reduction of drive characteristics of a motor is caused by clogging of a filter of a silencer or an abnormality of other elements of the compressor main body. CONSTITUTION: A filter is provided inside a silencer 7 equipped in a compression mechanism 5 of a compressor main body 2.
