Title: Flow rate detector
Inventor: OZAKI YUKINORI
IPC: G01F1/05
Filed: 1983-01-20
Abstract: PURPOSE:To obtain a small-sized, high-performance flow rate detector which suits to an automobile, etc., by swirling fluid by a fixed impeller within a flow- passage sectional range and detecting the number of rotations of a spherical body which rotates at right angles to the direction of the flow. CONSTITUTION:The fixed impeller 3 for swirling the fluid axially is inserted fixedly into a housing 1 and a ring 4 prevents it from falling off. A center shaft 6 united with the fixed impeller 3 has a tapered surface 7 expanding a flow passage and a taper surface 8 reducing the flow passage in the flow direction, thus obtaining a flowing-out preventing means for the steel ball 9. The steel ball 9 is provided in rotation groove 11 and 12 consisting of the tapered surfaces 7 and 8 and a flow-passage side wall 10. The number of rotations of the steel ball 9 is detected by a permanent magnet 13 and a magnetic detecting element 14 such as a magneto-resistance element.

Title: Production system
Inventor: NAGANAWA YUUJI
IPC: B23P19/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce the burden of a worker or programmer by changing the number of pieces of pallet working information to be worked into the working number changed by a working number changing means at the time of conveying the pallet to a numerically controlled machine tool. SOLUTION: Corresponding to the instruction of a central processing unit 8, a work conveyer 1 conveys a pallet, to which a lot of works are attached, to a plan station 7. At such a time, when a number is changed at the plan station 7, the number changed pallet working information is read and first working information data are read. Then, the working number of the first working information is checked and when the number of '0', that working is skipped. When the number is not '0', the registration into the common parameter of a numerical controller(NC) 6 is instructed to the NC 6. Thus, it is not necessary for the worker to perform confirmation by stopping a machine and the burden of the worker can be reduced.

Title: Spot generating device for preventing high voltage from remaining
Inventor: MORIKI JUNZO
IPC: H04N3/20
Filed: 1991-01-29
Abstract: PURPOSE:To prevent a high voltage from remaining in a CRT of a television receiver by emitting blue light instead of a white spot which is used in conventional high voltage discharging. CONSTITUTION:When a power switch is turned off, a switch 20 is opened to disconnect a capacitor 1 charged by a TV power source 5, and the electric charge of the capacitor 1 obtained by this TV power source 5 is discharged to the base of an output transistor TR 3 for B through a PNP TR 2, and a current flows to the cathode 3 of a CRT 4 by the output TR 3, and a high voltage in the CRT is discharged while displaying a blue spot on the picture. A high voltage is prevented from remaining in the CRT by the very simple circuit in this manner, and a viewer who is accustomed to the conventional white spot feels fresh because blue light is emitted. Red light, green light, or combination of two colors can be emitted if required.

Title: Position detector and magnetoresistance effect element
Inventor: TAKEDA NOBUHIRO
IPC: G01B7/00
Filed: 1995-01-24
Abstract: PURPOSE: To obtain highly accurate positional information by arranging a magnetic detector which changes in resistance value in response to a magnetic field of a scale section having magnetic poles magnetized alternately being separated at a distance equivalent to a forming width of the magnetic poles. CONSTITUTION: In magnetic detectors M1-M4 composing a magnetoresistance effect(MR) element, for example, a nickel-iron alloy film is made and fine lines are folded back by etching to form two wires. The detectors M1-M4 have the detectors M1 and M2 and the M3 and M4 formed being separated by a value equivalent to a forming width P of the magnetic poles at a scale section 7 to offset errors near the boundary of the N and S magnetic poles adjacent to each other and moreover, the detectors M1 and M2 and M3 and M4 are formed in phase deviated by a P/2 from each other in each detection group. As a result, when an increasing magnetic field is applied to a wire part 301 having the detector M1 connected to an external connection terminal 4, a decreasing magnetic field is applied to a wire part 301 having the detector M2 connected to the terminal 5 to cancel hysteresis property of a change in resistance value. The same is with the wire parts 303 and 304.
