IPC: H01F7/08
Filed: 1982-04-26
Abstract: PURPOSE:To reduce a cost through application of a low cost permanent magnet and to carry out fine adjustment of attracting force by respectively arranging the edge of armature where coil is provided at the gap formed at the edge of both yokes and by reducing magnetism of permanent magnet of Alnico system. CONSTITUTION:A is a cheap permanent magnet such as a ferrite magnet, while B is an expensive permanent magnet such as Alnico magnet which can easily be reduced in magnetism. Both permanent magnets are arranged in parallel so that the N and S poles are set in the same direction. The linear first yoke 1 is set in contact with the one end while the U-shaped second yoke 2 with the other end, and the edge of U-shaped armature 3 is movably set in the gap between the edges of both yokes. 4 is an excitation coil. Even when reverse field is applied to permanent magnets with the straight line L considered as operating point, both magnets are not reduced in magnetism even after the reverse field is eliminated. However, when a reverse field is applied with the straight line M considered as the operating point, since a reverse field is applied in such a manner that the straight line M exceeds the bonding point of the curve B, a value of magnetic flux density of permanent magnet B is reduced to BB'.

Abstract: PURPOSE:To get rid of unnecessary eddy which is unnecessary for particle separation and causes energy loss and heighten collection efficiency with whirling flow by placing a rectifying part consisting of a rectifying plate installed in the circumference of the surrounding of a conical rectifying body in the space immediately under the lower end part of an inner cylinder. CONSTITUTION:A mixed phase flow 5 of powdered particles and a fluid is supplied toward tangent line from a flowing-in cylinder 3 to a whirling cylinder 1 to generate a whirling flow 7 in the whirling cylinder 1 and the whirling flow is moved to the lower part from the upper part of the whirling cylinder 1. During the time, particles floating in the gas spring out in the wall side of the whirling cylinder 1 owing to the centrifugal force and descend spirally and are discharged out of the apparatus. The remaining fine powder, etc., with small grain size forms the whirling flow with a conveying air, etc., and is converged gradually from the wall side of the whirling cylinder to the axial part of the whirling cylinder and becomes a whirling flow with a small diameter and then moves immediate under an inner cylinder 2 and is led to the lower end part of a planer rectifying plate 11 and changes into an upward flow. A partial speed to the tangent line direction of the whirling flow is converted into a speed to only the axial direction by the rectifying part. As a result, unnecessary eddy is eliminated in the region under the inner cylinder.

Title: Current detecting circuit
Inventor: DEGUCHI KAZUHIDE
IPC: G01R19/00
Filed: 1987-03-23
Abstract: PURPOSE:To measure a large current by allowing a high-impedance voltage detecting circuit to detect a voltage which is developed by a current to be measured flowing to a diffusion resistor formed in the emitter area of a transistor (TR) whose base area is a terminal for the current to be measured. CONSTITUTION:The voltage detecting circuit 3a which has high input impedance is connected to the power TR 1 which has an emitter balanced resistor rE. Then when a current flows between the base and emitter of the TR 1, the voltage proportional to the quantity of the current is developed between the emitter and collector, but the input terminal impedance of the circuit 3a is infinite, so almost no current flows between the emitter and collector. The base-emitter current is calculated from the voltage detected by the circuit 3a and the resistance value of the resistor rE, so a large current can be detected without using any large detection resistor.

Abstract: PURPOSE: To provide smooth operation of a cylinder by installing an air-hydro converter in an air circuit to hydrolically operate a portion of the circuit.  
     CONSTITUTION: When an air circuit 17 for foward operation is connected with a pressurized air source 16, a piston 9a pushes a drilling head 5 in a forwarding direction. When the drilling head 5 has reached to a drilling finishing position and rotation of a work W is stopped, a direction control valve 15 shifts to connect an air circuit 18 with the pressurized air sourcd 16, thus supplying a high pressure oil from an air-hydro converter 21 to a cylinder chamber 9c used for retraction in a cylinder 9. Therefore, a piston 9b retracts and the drilling head 5 quickly returns to a drilling starting position. A little before the head 5 reaches to the drilling starting position, a direction control valve 25 shuts off flow of the high pressure oil.

Abstract: PROBLEM TO BE SOLVED: To prevent the quality of a recording image from degrading regardless of the opening rate of a modulation element. SOLUTION: A liquid crystal panel 30 having a plurality of liquid crystal cells is fixed to an LCD base 100 which is then secured to a support 102 through a leaf spring 101. The LCD base 100 is linked through an arm 33 with a drive section 31 telescoping under control of a subcontrol section 23. The subcontrol section 23 forms an image on the liquid crystal panel 30 based on an image data and exposed the image onto a print sheet 54 by irradiating the liquid crystal panel 30 with light through control of LEDs 25, 26, 27. Furthermore, the drive section 31 is controlled during exposure of the image to shift the liquid crystal panel 30 by a specified distance in a specified direction.  Since the liquid crystal panel 30 is shifted during exposure of the image, the exposing amount distribution is made smooth among the liquid crystal cells regardless of the opening rate of a modulation element and the image quality is prevented from degrading.
