Title: Manufacture of semiconductor device
Inventor: NISHIDA SOICHI
IPC: H01L21/28
Filed: 1993-06-23
Abstract: PURPOSE:To enhance a metal wiring material in step coverage by a method wherein a tapered contact hole is provided in an interlayer insulating film only by reactive ion etching. CONSTITUTION:A photoresist film 3 high in development solubility and a photoresist film 31 lower in solubility than the film 3 are successively laminated on an interlayer insulating film 2 by spin coating, exposed to light, and developed. As the photoresist film 3 is more dissolved than the photoresist 31 tat development, a photomask pattern of large overhang structure is formed. When the interlayer insulating film 2 is removed through a reactive ion etching method using this photomask as a mask, ions not only vertical but also oblique take part enough in etching, and a sputtering phenomenon caused by oblique ions is restrained from occurring on a resist film, so that a forward tapered contact hole can be formed.

Abstract: PURPOSE:To prevent a molded rib from inclining and occurrence of deformation such as strain by blowing a fluid in a parison under a condition wherein cores are forwarded and projected to a molding face side and thereafter retreating successively each divided core at least by two stages. CONSTITUTION:Cores 2a and 2b are forwarded by a specified amt. in the inside of a mold 1a and a compressed air is blown therein. A parison P is tightly adhered to the inner face of molds 1a and 1b and the cores 2a and 2b in such a way that it is tightly pressed against them to all the corners. Then, before the parison P is solidified, the cores 2a and 2b are successively retreated. At first, a free end part 2a' of the core 2a is retreated by actuating a hydraulic cylinder 6a in such a way that it is made at the same plane as the inner face of the mold 1a. Then, by actuating another hydraulic cylinder 6b, the remaining core 2b is retreated in the same way as the core 2a. As the result, a rib is formed by cores 2a and 2b divided into two. In this case, a synthetic resin at a position integrally press-adhered by the previously retreated core 2a supports a synthetic resin at a position of the afterward retreating core and prevents it from deformation such as inclination thereof.

Title: Tracking of optical head and actuator for focusing
Inventor: UEI HON RII
IPC: G11B11/105
Filed: 1989-06-16
Abstract: PURPOSE: To provide an actuator which is made compact by installing a first moving means which performs tracking by moving an optical element and a coupling means along a first path and a second moving means which performs focusing by moving the object lens to the optical element. CONSTITUTION: When current is made to flow in the magnetic coil 46, a force is generated by the interaction appearing between the magnetic field of the coil 46 and the magnetic flux generated in the magnetic circuit formed by the magnets 36, 38 and magnetic pole pieces 20, 22. By this force the tracking actuator is made to move in the horizontal direction. When the magnetic coil 46 moves, the object lens 34 and the light-deflecting mirror 48 are made to move by the same distance. Since the mirror 48 is coupled with the object lens 34, these optical parts are made to move simultaneously and parallelly to the beam 29 coming from the holographic optical head 28 and the relative positions between the object lens 34 and the laser beam 29 remain fixed.  Because of this, the laser beam is not displaced from the object lens and thereby long- distance movement of the tracking actuator is made possible.

Title: Hybrid power train system for vehicle
Inventor: ITOYAMA HIROYUKI
IPC: B60L50/16
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To perform regenerative power generation while obtaining a good engine brake effect. SOLUTION: Drive wheels 7 of a vehicle are provided with a second motor 8 so that an engine 1 and the device power can be combined. A basic regenerating amount table is established which converts pump loss into braking force in accordance with the number of revolutions of the engine 1. Also, a regenerating amount correcting table is set up which corrects the basic regenerating amount so that slowing down is sensed as desired by a driver when stepping on a brake. While the vehicle is slowing down, fuel supply to the engine 1 is cut and the basic regenerating amount is read out from the basis regenerating amount table based on the revolutions of the engine 1. Unless the brake pedal is stepped on, the basic regenerating amount is generated. When it is stepped on, a correcting coefficient is read out from the regenerating amount correcting table based on the speed of the vehicle.  The basic regenerating amount is multiplied by the correcting coefficient and the regeneration of the second motor 8 is controlled so as to generate the corrected regenerating amount.

IPC: H04N7/16
Filed: 1986-06-30
Abstract: PURPOSE:To improve responsiveness in a tension control system, by using a speed control system for a minor loop of the tension control system, while calculating a motor revolving speed corresponding to a line speed based on the winding diameter found out of a roll peripheral velocity and the motor revolving speed, and compensating the winding diameter with this revolving speed as a command of the speed control system. CONSTITUTION:A variable speed servomotor 2 is controlled for its speed so as to make a peripheral speed v1 of a roll 1 accord with a line speed v2, compensating a winding diameter. That is to say, along with an increase in the winding diameter, a speed command is reduced, and reversely it is increased along with a decrease in the winding diameter, varying a revolving speed N of a motor 2 according to increase or decrease of the winding diameter D, and the roll peripheral speed v1 is followed to the line speed v2. After a limiting current is made to flow in advance of line system motion, and tension acting at that time is detected, setting of the initial value of the winding diameter D of the roll is found out the said tension and the current value by operation. In addition, since it is so constituted that the speed command follows at once to respective variations in the like speed, the winding diameter and the motor revolving speed, this motor revolving speed is adjustable to the optimum value in the early stage so that responsiveness is excellent.

Filed: 1978-12-13
Abstract: PURPOSE: To obtain a molding coal composition useful as a solid fuel having a greatly increased strength, especially at high temperatures, from residual oil obtained from the distillation of naphtha-cracked tar and original coal.  
     CONSTITUTION: A hundred wt part of original coal is mixed with 4W13 wt parts of residual oil of a softening point of 10W80°C, preferably 20W60°C, obtained from the distillation of naphtha cracked tar. If the softening point of the residual oil is 10°C or less, the strength of molded coal obtained becomes so low that the loosening of molded coal occurs when handling because the residual oil as binder is too soft, but if it exceeds 80°C, the strength of the molded coal becomes low likewise because the residual oil as binder is too high in viscosity. Also, the proportion of the residual oil should be in the range from 4 wt parts to 13 wt parts, or the sufficient strength of molded coal could not be obtained.
