Title: Control of disintegration in preparation of powdered coke for sintering use
Inventor: ISHII KOUICHI
IPC: B02C25/00
Filed: 1979-09-27
Abstract: PURPOSE: To prevent the fluctuation of the particle size distribution of powdered coke, by sampling the powdered coke crushed with a rod mill continuously, measuring the particle size of the sample, and controlling the rotational speed of the rod mill to adjust the measured size to the target value.  
     CONSTITUTION: Powdered coke in the tank 1 is fed to the sieve 3 through the belt feeder 2 and the belt conveyor 7-1, and e.g. separated into the coarse fraction having the particle size of ≥5mm and the fine fraction having the particle size of ≤5mm. The coarse fraction is fed to the rod mill 4 through the conveyor 7-2, crushed, and fed to the sieve 6 through the conveyors 7-3 and 7-4. In the course of the transfer, a part of the powdered coke is sampled with a belt sampler 5, and dropped to the conveyor 7-4. The falling powdered coke is watched with a high- speed TV camera 8, and the signal from the camera is transmitted to the particle- size detector 9. The data analyzed in the detector 9 is inputted into the arithmetic unit 10, which compares the data with the preset target value, and controls the rotational speed of the rod mill 4.

IPC: B41J25/24
Filed: 1979-09-28
Abstract: PURPOSE: To prevent an increase in a load of a vertical movement by means of a rotation torque produced in the case of rotation selection and to lengthen a mechanism life and improve an accuracy thereof, by a method wherein, in a type selection mechanism of type head, a mechanism is adopted to a portion where a rotation motion and a vertical movement are transferred.  
     CONSTITUTION: A slide sleeve 2', equipped on a type head 1, performs a vertical movement resulting from the rotation in a direction (d) of a vertical drive force transmission arm 3 centering around an axis 14. In the meantime, a rotation motor 7 spins a motor shaft 9, and the rotation of a torque piece 6' secured on a shaft 9 is transferred to a slide sleeve 2' through the working of a hinge mechanism consisting of hinge plates 8 and 10 to perform a rotation motion. The slide sleeve 2' is vertically slided smoothly thereupon resulting from the opening and closing motion of the hinge mechanism centering around a pin 13.

Filed: 1989-05-17
Abstract: PURPOSE:To prevent malfunction of correction by controlling a bit inverting circuit with a correction enable inhibit signal outputted from a mis-correction preventing circuit when a function correcting an error bit is not normally operated. CONSTITUTION:A mis-correction preventing circuit 9 to prevent malfunction is provided.

Title: Adjusting device of die lip
Inventor: TSUKAMOTO HIDEO
IPC: B29C48/08
Filed: 1985-06-10
Abstract: PURPOSE:To enable to adjust the gap of a slit beyond the range of elastic deformation of a flex lip, to say nothing of within the range of elastic deformation of the flex lip by a method wherein the flex lip is energized through the clamping screw of laminated plates by expanding and contracting piezoelectric elements so as to narrow or spread the gap of the slit. CONSTITUTION:When the gap of a slit 2 is intended to narrow, the electric voltage to apply to piezoelectric elements 104 is raised gradually so as to expand the laminated plates of the piezoelectric elements 104 in order to extend the clamping screw 114 of the laminated plates. Thus, a flex lip 3 is energized through a bottom plate 113 so as to narrow the slit 2. When the gap of the slit 2 is intended to spread, the electric voltage to apply to the piezoelectric elements 104 is lowered gradually so as to contract the laminated plates of the piezoelectric elements 104. Consequently, the clamping screw 114 of the laminated plates also restores itself by its own elastic force and, as a result, the flex lip 3, with which the clamping screw 114 of the laminated plates engages threadedly, is also pulled back, accordingly, the slit 2 is spread. As mentioned above, not only the pushing-forward of the flex lip 3, but also the flex lip 3 beyond the range of elastic deformation can be pushed back.

Abstract: PURPOSE:To achieve an excellent phase switching without using an inverter, by connecting an ouput of inphase and opposite phase accompanying an amplification operation as an input signal, through the connection of a switching circuit in forward and reverse manner, in a phase comparator for phase locked loop for audio devices. CONSTITUTION:When a switching circuit SW is operated to a + contact side, a bias voltage is applied to the base of a transistor (TR) Q5 out of the TRs Q5, Q6 of a differential pair. Thus, the TRQ5 is turned on and a prescribed constant current flows to TRs Q1, Q2 out of the TRs Q1, Q2 and Q3, Q4. Thus, a signal applied from an input signal source VIN to the TRQ1 is outputted OUT as an output signal of inphase component accompanying the specified amplification operation. Similarly, when the circuit SW is switched to a - side contact, the bias voltage is applied to the base of the TRQ6 of the differential TR pair Q5, Q6. Then, the specified current flows to the TRs Q3, Q4 and an input signal applied to the TRQ4 via a resistor R2 is outputted as an opposite phase component with the specified amplifying operation.

Filed: 1991-05-29
Abstract: PURPOSE:To prevent coming-off of a lead by reduction of a binding strength under a high temperature or fuse melting in installing a safely element by bonding a terminal of the safely terminal to an electrode on a thermal conductive substrate by ultrasonic joining. CONSTITUTION:A lead 2A of a thermal fuse 2 is jointed to electrodes 1D, 1F by ultrasonic joining. The lead 2A is set to have a rectangular cross section for increasing a contact surface at this time, it is put to get in contact with the electrodes 1D, 1F under a pressure, and ultrasonic vibration is given in the direction of an electrode surface for ultrasonic joining. With the ultrasonic joining, a joining strength is kept without decreasing up to near a fusing point of metal to be jointed, and a high temperature is not generated at the time of joining. Reduction of the joining strength at a high temperature which causes coming-off of a lead, or melting of the fuse by heat transmitted from a soldering iron in installation of the thermal fuse can thus be prevented.

Abstract: PURPOSE:To increase the intensity of a diffraction image of a diffraction grating spectroscope at a focal plane, by focusing an image of a light source on an incident slit by using an out-of-axis spherical mirror. CONSTITUTION:A light from a light source 1 focuses an image on an incident slit 3 by a light source condensing mirror 2 and an incident light is reflected by a plane mirror 4 and then, is converged by a light condensing mirror 5 to make incident to a diffraction grating 6 at a Monkgrees on type spectroscope. Zero-order light is reflected by the grating 6 and is focused into the image of incident slit 3 at the position of converging point of the mirror 5 and the position having the same distance S to the grating 6. But, this position of image formation in only a horizontal face of the incidert slit and the distance P to the position of image formation in the vertical direction is largely extended. Accordingly, the image of the source 1 is formed in the rear from the slit 3 in the vertical direction by using an out-of-axis spherical mirror as a light source condensing mirror 1 and the slit images of horizontal and vertical direction are formed on a focal plane 7 of diffracted light. Hereby, the intensity of diffracted image on the focal plane is increased.
