Title: Impeller for pump
Inventor: TANABE MASATOSHI
IPC: F04D29/24
Filed: 1979-11-19
Abstract: PURPOSE: To increase a productivity of an impeller for a pump by a method wherein an end part of a vane formed integrally on either one of a front shroud or a rear shroud is welded to a recessed part provided on the other shroud by supersonic waves.  
     CONSTITUTION: A projection 28, provided on an end part of an outer wall 26 of a vane 22 formed at an internal surface of a front shroud 12, is provided at a deviated position from a center line of the outer wall 26 toward a hollow part 24 side by δ. The tip end of the projection 28 is formed so as to have an acute angle. The front shroud 12 and a rear shroud 14 are integralized to form an impeller for a pump by a method wherein the tip end of the projection 28 is fused by supersonic waves and is welded to a recessed groove 30 on the rear shround 14. Thus, the outer wall 26 of the vane 22 provided on the front shroud 12 is welded to the recessed groove 30 provided on the rear shroud 14 by the supersonic waves to form the both shrouds 12, 14 integrally, therefore, a work therefor is facilitated and a productivity thereof is increased.

Title: Multipiece rim
Inventor: WATANABE RYOICHI
IPC: B60B21/00
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent or suppress fretting of a lock ring groove by forming a lock ring relief groove in the position of the lock ring groove connected from the R part of a rim shaft direction outer side to the side wall part of the outside so as to be recessed in a side away from the lock ring and extended over the full length of the lock ring groove peripheral direction. SOLUTION: A lock ring relief groove 9 is formed in the part of a lock ring groove 6 connected from the R part 6c of an axial direction outer side to the side wall part 6b of the axial direction outer side so as to be recessed in a side away from a lock ring 2 and extended over the full peripheral of the peripheral direction of the lock ring groove 6. Preferably, the lock ring relief groove 9 is formed to be circular-arc in section for preventing its contact with the lock ring 2 of a groove surface. Also, small R parts are formed in a boundary 9b between the lock ring relief groove 9 and the R part 6c and in a boundary 9a with the side wall part 6b so as to prevent the concentration of stress therein. Thus, without any surface contact loads placed on the part connected from the R part 6c to the side wall part 6b, a fretting resisting effect is improved.

Title: Cordless digitizer
Inventor: MATSUSHIMA KEIICHI
IPC: G06F3/046
Filed: 1992-05-18
Abstract: PURPOSE:To make it possible to omit an external circuit for driving a position indicator and a cord for connecting the external circuit to the position indicator. CONSTITUTION:When sine and cosine wave signals are respectively applied to two driving coils x1, x2 in a tablet 1, the position indicator 2 held in electromagnetically coupled status with the tablet 1 is driven and generates a magnetic field and the position of the indicator 2 can be calculated from voltage induced in the 1st and 2nd receiving coils y1, y2, so that an external circuit for driving the indicator 2 or a cord can be omitted. Since the whole positions of the indicator 2 in the X and Y directions are detected from the 1st and 2n detecting coil groups Zx, Zy, the partial position in the Y direction is calculated from the induced voltage values of the receiving coils y1, y2 and the partial position in the X direction can be calculated from a phase difference between the induced voltages and the driving signals applied to the driving coils x1, x2, a scanner for detecting the position is made unnecessary.

Title: Semiconductor switching circuit
Inventor: MURAKAMI KOUICHI
IPC: H01L29/78
Filed: 1982-08-30
Abstract: PURPOSE:To reduce switch drive current and power loss and enable to integrate circuits by a method wherein a detection resistance for detecting the short circuit of loads is unnecessitated, and then protection circuits are composed of MOS transistor sources which are grounded. CONSTITUTION:When a switching signal VIN is inputted, the gate voltage VG1 of an MOS transistor TR 12 increases at the time constant decided by the gate capacitances of a resistor 14 and the TR 12. When the voltage VG1 reaches the threshold voltage of the TR 12, the TR 12 conducts, and then the drain voltage VDS begins to decrease. When the voltage VG1 increases and reaches the reference voltage VE of a comparator 15, the output signal V1 of the comparator 15 turns at H level. But, the output V2 of an AND circuit 16 is at L level, and the output of a latch circuit 17 also turns at L level, accordingly a MOST TR 13 becomes non-conducted, and the TR 12 becomes conducted. On the other hand, TR 12 maintains non-conduction at the time of the short circuit of the load 11. This constitution unnecessitates a detection resistor for load short circuit. In this constitution, the TR 13 and the circuits 15-17 are composed of MOST TR's sources being grounded.

Filed: 1990-06-07
Abstract: PURPOSE:To obtain a cleaning agent compsn. with good foaming properties, reduced sliminess after rinsing and reduced irritativeness to skins by compounding a cationic surfactant with a specified polyethyleneimine polymer. CONSTITUTION:A copolymer (A) with repeating units of formulas I and II (wherein R<1> is H, CH3 or C2H5; R<2> is a 4-15C alkyl, aryl or aralkyl) in a wt. ratio of formula I to formula II of 9/1 to 1/9 (polyethyleneimine polymer) and a cationic surfactant (B) (e.g. octadecyltrimethylammonium chloride) are compounded. Even though the cationic surfactant has not only cleaning power but also bactericidal and bacteriostatic actions and is used for a skin cleaning agent for sterilization such as a cationic soap, there exist defects such as poor foaming, coarse foam and remaining of unpleasant sliminess after rinsing. It is possible by the abovedescribed combination to obtain a cleaning agent compsn. with good foaming reduction in unpleasant sliminess after rinsing and reduced irritativeness to the skins.

Abstract: PURPOSE:To obtain availability for control over a dust respirator and health control and to ensure the precision of an inspection result, by sorting and measuring particulates of the same specific sizes by respective detectors, and comparing the amounts of fine particles measured by both detectors with each other. CONSTITUTION:Suction pumps incorporated in an upstream-side detector 11 and a downstream-side detector 13 are put in operation and the suction is carried on while both suction pumps are set to an equal suction speed; and both detectors 11 and 13 are set to the same measured particle size selection range, and then an arithmetic processing mechanism 14 calculates the sensitivity difference between the detectors 11 and 13 and the flow passage condition as blank values. Both numerals counted by both detectors 11 and 13 are compared with each other by the arithmetic processing mechanism 14. While the blank values are corrected, the percentage of the counted value of fine particles by the downstream detector 13 to that by the upstream detector 11 is displayed digitrally on a display device 15, obtaining the result of a performance test of a filter material 1.

IPC: H01L21/673
Filed: 1982-08-30
Abstract: PURPOSE:To produce the carrier tape adaptable to multiple kinds of small quantity production by a method wherein the part holding each item to be carried is arranged in the longer direction of a tape while the identification signals are recorded in the part corresponding to the holding part. CONSTITUTION:The picked up acceptable pellets 9 are fed to the holding part 7 of a tape 1 intermittently sent out by the holes 8 and the feeling pawls to be contained in a hole 6 and successively held by an adhesive layer 5. At this time, the identification signals interlocking with the feeding unit and corresponding to the pellets 9 are recorded in the holding part 7 of a magnetic recording tape 4 and adjoining position thereto. Therefore, e.g. when the pellets 9 are picked up in case of a connecting operation, a recorded signal in the tape 4 may be reproduced to identify its kind. In such a constitution, the pellets of multiple kinds may be carried on the same tape preventing any erroneous identification of the kinds from occurring producing the carrier tape adaptable to multiple kinds of small quantity production.
