Title: Waveform shaping circuit
Inventor: HASEGAWA TSUNAO
IPC: H03K5/08
Filed: 1984-02-22
Abstract: PURPOSE:To reproduce a waveform before its transmission or recording and reproducing even if an inter-code inteference is generated, and to prevent the generation of a code error by varying a threshold level in accordance with a code of a bit existing in front of each bit in a bit sequence. CONSTITUTION:An input IN1 is compared with each different voltage value V1-V4 by plural comparators 2-5. These compared outputs become input signals C0-C3 of a multiplexer 6. The fact that the multiplexer 6 selects any of these input signals C0-C3 is controlled as shown in the table. A clock IN2 of D-flip-flops 7, 8 is generated in the intermediate point corresponding to each bit, therefore, outputs of the multiplexer, which are the immediately previous output and the output before said output are stored in each D-flip-flop 7, 8, and based on this value, a threshold level by which the next bit is compared is determined. According to the control of the table, if both the last time and the last time but one are L, the threshold level is made low, and when the last time and the last time but one are H, the threshold level is made high.

Filed: 1983-02-28
Abstract: PURPOSE:To prevent a bounding occurring at a low speed rotating time and a light load time by providing a chopper type power source between a rectifier and an inverter and detecting the regenerative current to turn a transistor OFF.

IPC: H01L21/22
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a wafer boat for vertical furnace which can be constituted in such a way that the boat can exhibit a significant effect on the yield improvement of a device, is hardly affected by thermal stresses by suppressing the occurrence of stresses due to the own-weights of wafers when the diameters of the wafers are increased and the treating temperature is raised, and can reduce the influence of slips on the characteristics of the device by preventing the occurrence of the slips at the contacting sections of the wafers with the wafer boat during heat treatment in a vertical vapor growth furnace.

Title: Optical head device
Inventor: MIYAJIMA GIICHI
IPC: G11B11/10
Filed: 1989-02-09
Abstract: PURPOSE:To reduce an installing space by providing a yoke in the direction of optical axis of an optical system piercing through the optical system, winding a coil across the yoke, and generating a magnetic field in the direction of optical axis of the optical system. CONSTITUTION:The yoke 33 mounted on an optical member supporting part 7 and bent at right angles pierces through the center axis of an objective lens 15 in the direction of optical axis. The magnetic field can be generated at the tip of the yoke 33 by permitting a current to flow on a bias coil wound across the rear end part of the yoke 33, and it is concentrated on an opposite yoke, and is applied on the magnetic film of a medium 34. At such a case, the diameter of the yoke 33 is formed sufficiently less than that of a beam of light made incident on the lens 15, which reduces optical influence. Since such constitution is employed, stick slippage between the yoke 33 and the through hole of the lens 5 can be prevented occurring even at a state where the lens 15 is operated as generating the tilting of an optical axis by clearance at the time of driving the lens 15 in a focusing direction, and a smooth action can be obtained, which attains the miniaturization and thinning of the device.

Title: Aluminum blast furnace
Inventor: AMANO KOUICHI
IPC: F27B1/00
Filed: 1983-02-28
Abstract: PURPOSE:To center the flow of high temp. gas and to apply effectively heat to the briquettes in a pipe by feeding the coke-contg. bauxite briquettes through a center feed pipe to the high temp. region at the top end of a raceway and charging coke on the circumferential wall side. CONSTITUTION:The coke in a coke bunker 16 is supplied successively through a coke feed port 15 into the position in proximity to the furnace wall in a furnace mouth part 14 and forms a conical pile, from which the coke flows into the upper part of a raceway 3 and reacts with the O2 from a tuyere 2, thus forming high temp. gas. Since the high temp. gas has the smaller pressure drop in the central part of the furnace than in the wall part thereof, the gas is easier to rise along a center feed pipe 4 at the center. On the other hand, the coke-contg. bauxite briquettes or aluminum ores in a briquette bunker 5 are preheated by the high temp. gas ascending through many small holes of the pipe 4 during falling in the pipe 4 and are reduced in the bottom end part of the pipe 4, by which the ores are made into a crude Al alloy. Said alloy drops onto a furnace bottom 24 without passing through the inside of the raceway 3.

Title: Thin film magnetic head
Inventor: TAKAGI MASAYUKI
IPC: G11B5/31
Filed: 1985-02-22
Abstract: PURPOSE:To reduce the influence of stress and shape, 90 deg. magnetic domain and to improve an SN ratio by optimizing the shape of the edge part 3 of a magnetic pattern. CONSTITUTION:It is assumed that the flat pattern shape of a magnetic material, that is, the 1st and 2nd magnetic layers, has an angle extending from a medium facing surface to its opposite side and the edge part of the pattern is in a shape, which has an undulation composed of an arbitrary shape. Namely, since the pattern end part 3' of the magnetic pattern turns out to by a curve with a comparatively small curvature, the magnitude of internal stress in this part is decreased, and the influence of the shape upon a nonmagnetic field is curved, thereby reducing the 90 deg. magnetic domain area 2'. Accordingly the signal vs noise ratio of a magnetic head can be improved.

Title: Suppression device of switching surge
Inventor: OOHASHI HIROSHI
IPC: H01H33/59
Filed: 1978-03-22
Abstract: PURPOSE: To relax voltage regulation at repeated reignition time, and prevent dielectric breakdown of insulation of winding of a motor, by connecting a condenser among phases of at least one side terminal part of electric source side or load side of a breaker.  
     CONSTITUTION: Condenser C is inserted among phases of, for example, load side terminal of a breaker 1. When a motor is broken by a breaker which has excellent high frequency breaking capacity, over voltage due to repeated reignition has big voltage regulation, and therefore, it is almost impressed on the first coil of the winding. when there is no surge suppression device and intervals of poles of the breaker are ignited in 2 or 3 phases at one time, voltage partial charge ratio of the first coil is, for example, about 60%, as shown in the figure, and electrostatic capacity which is needed to drop the voltage partial charge ratio to 50% is calculated as about 0.01μF. Therefore, voltage regulation of repeated reignition surge at breaking time of motor load or the like can be relaxed, voltage partial charge ratio is reduced, and dielectric breakdown of insulation can be prevented.

Filed: 1991-02-27
Abstract: PURPOSE:To simplify the dieing, the combination, and the molding and facilitate the retention even at baking and annealing by making use of the coupling by calking, in a process of manufacturing a low-cost yoke excellent in magnetizing property and a yoke in optional shape by combining and baking magnetic materials. CONSTITUTION:The object, where plating is applied on the surface of a magnetic material, is stamped out with a punch or the like, considering the final shape, but in this case the coupling between laminations is performed by calking 4. This calking 4 is one being generally performed at the same time in the dieing process such as punching. But, after dieing such as punching, etc., the coupling by calking may be performed. After performing the calking process, the annealing for causing the baking between magnetic materials by plating layers is performed. Hereby, the complexity of shape maintenance of a molded item during combination, baking, or annealing as in a conventional method vanishes.

Abstract: PROBLEM TO BE SOLVED: To judge the failure of a detecting means accurately and positively by judging the failure of the detecting means for detecting the rotation of a rotating member from the input state of electric signals in a gear speed stage where the electric signals are inputted to at least two shift control solenoids. SOLUTION: At the time of detecting the failure of an input rotation sensor 21 serving as a detecting means, in case of confirming a gear speed stage to be the second gear speed by an electronic control unit 30, whether there is input from the input rotation sensor 21 while there is four-pulse input from an output rotation sensor 22 is checked.
