Title: Detector-controller for clearance
Inventor: YAMAMORI FUDETO
IPC: B21D43/00
Filed: 1979-11-06
Abstract: PURPOSE: To detect the rising slug, and to suitably control the action of the press machine, by installing the detector in the bottom surface of the moving stripper of the press die unit, and by detecting the clearance between the die and the moving stripper reciprocating against this die through the work.  
     CONSTITUTION: The detectors 21aW21d are installed at four corners of the bottom surface of the moving stripper 9 of the press die unit so as to sink to 1mm depth from the bottom surface. These detectors are located outside the work 3 and directly face to the upper surface of the die 2 placing a distance; hereby, the detectors always detect the clearance (d) between the upper surface of the die 2 and the bottom surface of the moving stripper 9. When the detected value is smaller than the value, 1mm plus thickness of the work 3, the control device does not produce the signal; if the slug 3b exists, the value (d) becomes larger than the value, 1mm plus thickness of the work 3, and it is detected by the detector which then produces a signal. By this signal, the motor for driving the press machine is stopped; hereby, the damage of the stripper 9 and the die 2, owing to existence of the slug generated by the press work, is automatically prevented.

Filed: 1978-11-21
Abstract: PURPOSE: To attain simple and rapid measurement by obtaining current density in one of needed regions by measuring current values in several regions sharing at least one boundary and then by processing them by adding or subtracting.  
     CONSTITUTION: Electron beam 2 is shaped by 1st stop 5 with rectangular opening 5-1 and the sectional size of the electron beam passing through rectangular hole 8-1 of 2nd stop 8 is controlled by deflector 7 controlled by an external signal. Then, when current density distribution is measured by obtaining current density in each region obtained by partitioning the section of the electron beam, current values in several regions sharing at least one boundary with region A are measured and the current value in this region is calculated repeatedly by adding or subtracting those current values, thereby obtaining the current density. Consequently, simple and rapid measurement is possible even if current density distribution would be uneven.

Title: Heteroepitaxial growth method
Inventor: TAMAMURA KOJI
IPC: H01L21/205
Filed: 1988-06-11
Abstract: PURPOSE:To enable heteroepitaxial growth of an improved single-crystal semiconductor layer with low crystal defect density such as dislocation to be made on a silicon substrate by forming the single-crystal semiconductor layer which is different from silicon on the silicon substrate after forming recessed and protruded parts on the surface of the silicon substrate. CONSTITUTION:A plurality of grooves 1a with for example a triangular sectional area shape are formed on a silicon(Si) substrate 1 with {001} orientation in parallel with each other for forming a grating shape and a single-crystal semiconductor layer which is different from Si, for example a single-crystal gallium arsenic(GaAs) layer 2, is allowed to grow on this Si substrate 1. As a result of this growth, the dislocation penetrates the single-crystal GaAs layer 2 and this penetrating dislocation is bent in the direction away from the <001> in the process where the growth direction changes gradually in a direction for higher index, for example <110> direction, so that propagation of penetrating dislocation toward upper layer can be restricted. Thus, an improved single- crystal semiconductor layer 2 with low density of crystal defects such as dislocation can be formed on the Si substrate 1 by a heteroepitaxial growth method.

Title: Ripple smoother
Inventor: TAKEUCHI MAKOTO
IPC: F16K17/04
Filed: 1984-07-11
Abstract: PURPOSE:To change the equilibrium pressure for smoothing to any desired value by providing a contrary force to motion of a movable member in the condition that it has moved apart from the reference position. CONSTITUTION:A leftwise force F1 of a magnitude in compliance with the pressure of fluid is applied to that surface of piston 8 which is in contact with the fluid. At the same time, a rightwise force F2 is applied to this piston 8, which is generated when a moving member 7 is attracted by a magnet 6. A coil spring 10 is so adjusted that the force applied to said moving member 7 by the spring 10 will become zero when the moving member 7 lies in its reference position with the fluid pressure taking the specific value to give the equilibrium state. Accordingly the piston is returned to its initial reference position after the fluid pressure is restituted to its original level as under the equilibrium state.

Title: Wire bonding pad device
Inventor: TAKIZAWA KEIICHI
IPC: H01L21/60
Filed: 1989-06-08
Abstract: PURPOSE:To arrange wire bonding pads with a high density by a method wherein the wire bonding pads are arranged in a zigzag manner, a width of conductors in a faced part is made narrower than a width of conductors in other parts, and a width of a first conductor group and that of a second conductor group are made substantially equal. CONSTITUTION:Wire bonding pads 161 are arranged in a zigzag manner; conductors 16 connected electrically to the wire bonding pads 161 are formed; in addition, bonding wires 17 which have been wire-bonded to the wire bonding pads 161 are formed. A width C of the conductors 16 in a part E adjacent to the wire bonding pads 161 is narrower than a width D of the conductors 16 in other parts. That is to say, since the width in the part E of the conductors 16 is made narrow, an arrangement density of the wire bonding pads 161 can be increased. Thereby, a pitch of the bonding pads can be made small and highly dense.

Abstract: PURPOSE:To reduce the number of steps and the size of an object by preferentially assigning the register having the same value as data whose reference point is latest out of data having the same value as registers in case of existence of plural registers having the same value at the time of requesting a register. CONSTITUTION:When a same value relation setting request is issued to a regis ter managing part 1, a same value relation setting means 3 stores information, which indicates that registers and data have the same values, in a management information storage means 2. When a register request is issued to the register managing part 1, a register assigning means 4 refers to a register use state RC in the management information storage means 2, and a register in the un used state is returned if exists. If there are registers in the unused state, it is checked whether a register having the same value as data exists or not; and if there are plural registers having the same value as data, it is checked whether the register having the same value as data which is not referred here after exists or not. If it exists, it is returned; but if it does not exist, the register having the same value as data which is referred latest is returned. Thus, the number of steps and the size of the object are reduced.

Title: Method of cooling feed-secrew-shaft of straight-line-motion-generating mechanism
Inventor: KAMIMURA ICHIRO
IPC: F16H25/20
Filed: 1986-06-19
Abstract: PURPOSE:To obtain a sufficient cooling effect without using a rotating sealed-joint, by providing a through hole, through which the cooling fluid passes, to the inner part of a screw shaft, whose both ends are fixed to a base table and which is threadedly engaged with a nut in such a manner that the nut can freely rotate. CONSTITUTION:Both ends of a sliding screw shaft or a ball screw shaft 2 are fixed to a base table 1. A rotor 3 of a motor M is threadedly engaged with the shaft 2 by means of a nut 4 in a freely rotatable manner. Meanwhile, a stator 6 fixed to a moving main body 7 is loosely fitted to the periphery of the rotor 5 fixed to a rotor shaft 3, thereby converting the rotational force of the motor M into a straight- line motion of the moving main body 7. A through hole 8 for the cooling liquid is made inside the screw shaft 2 in the axial direction, so that the fluid is introduced from an inlet port 9 and is discharged from an outlet port 10. With this contrivance, a high pressure fluid can be used because this mechanism does not need a rotating sealed-joint for the fluid. In addition, the diameter of the through hole 8 can be increased, thereby enlarging the heat transfer area. Therefore, it becomes possible to suck in the outdoor air as it is for cooling.

Title: Reel for tape cassette
Inventor: SODA MASAHIKO
IPC: G11B23/087
Filed: 1993-06-16
Abstract: PURPOSE:To prevent the generation of crack on a flange due to the pressing force of a horn for ultrasonic bonding when a reel is assembled by providing a seat part of a specified height around the center pin of the reel. CONSTITUTION:The seat part 19 is provided at the upper surface 15 of a fitting part 8a on the lower flange 8 of the reel 18 by building up in the range of 6mm diameter around an axial center of the center pin 9 so as to avoid an ornamental hole 8b. At this time, a gap (b) between the upper surface of the seat part 19 and the lower surface 16 of the upper flange 13 is formed to 0.02mm. When the ultrasonic bonding is executed for fixing the upper flange 13 while pressing a calking pin 10 by the horn 14, the tip of the horn 14 comes up to the upper flange 13, and the lower surface 16 deflects downward and abuts on the seat part 19. By this procedure, the deflection is suppressed to <=0.2mm to prevent the generation of the crack, and the yield at the time of manufacturing the reel is improved, and also a synthetic resin material is usable for the quality of the flange material, thereby reducing the cost.

Title: Image forming device
Inventor: KAN FUMITAKA
IPC: H01J29/04
Filed: 1986-06-23
Abstract: PURPOSE:To obtain sufficient brightness without need for a complicated XY matrix drive circuit, by making transfer shift of image information between memory elements which have means of driving an electron beam source and an electron beam detecting means. CONSTITUTION:If an electron beam enters an electron detecting means D, electric charge is once stored in this electron beam detecting means D. When the electric charge is transferred to a driving means T to turn it on, an electron beam source E is driven to emit an electron beam corresponding to the electric charge stored in the electron beam detecting means. For example, 2 units of such a memory element are arranged to deflect the emitted electron beam by the effect of electric field and magnetic field and to make it enter the electron beam detecting means area of a different memory element, in order to perform 2-dimensional transfer of image information. Because the trajectory of the electron beqam depends on the intensity of magnetic field, the electron beam can be transferred to a desired memory element by selecting proper magnetic field intensity. Thus above-mentioned shifting operation enables to obtain a function equivalent to that of an XY matrix drive circuit.
