Title: Method for confirming precision of pressing
Inventor: KOMATSU TOSHIHIKO
IPC: B21C51/00
Filed: 1993-05-24
Abstract: PURPOSE:To make a surface plate or a layout machine needless and to reduce the equipment cost and the man-hours required to confirm in confirming the precision of pressing. CONSTITUTION:In producing pressing products via plural working processes, at first, in one process among plural working processes, a projection part for inspecting 3 having an inspection surface 3a of truncated conical shape is formed on a subject to be pressed for producing the pressing products. Next, in one process, at least, after the above one process among plural working processes, the inspecting projection of the subject to be pressed is clamped with a punch and a die provided on a prescribed position so that a prescribed clearance is opened if the position of the inspecting projection is within a prescribed working precision. Then, after surveying the inspection surface 3a, in the case that a flaw B is generated on the inspection surface due to the interference of the inspection surface with one side, at least, of the punch and the die, the pressing products is judged as the working precision is not good.

Title: Thermal cvd device
Inventor: HOSOKAWA IWAO
IPC: C23C16/46
Filed: 1991-04-25
Abstract: PURPOSE:To uniformize the growing speed of a film on a susceptor by applying a temp. gradient to the susceptor disposed in the gaseous raw material flow in a reaction chamber. CONSTITUTION:A wafer, which is a single crystal of silicon, etc., is imposed on the susceptor 2 made of a material, such as ceramics, which is hardly oxidizable, in the reaction chamber having a cooling surface 1 on the upper surface. A heater 3 disposed on the lower surface of the susceptor is divided perpendicularly to the flow of the gases and predetermined electric powers are supplied to the respective divided heaters to provide the temp. gradient in the gas flow direction of the susceptor 2. The reactive gases flow in from an arrow 7 and form the thin film on the wafer of a high temp. surface by a pyrolysis reaction. The remaining gases are discharged toward an arrow 8. The above-mentioned temp. gradient may also be imparted by the varied densities of the disposed heaters, etc., and other means. Further, chaos-like flow is preferably generated in the gaseous raw material flow by controlling the temp. of the side wall surfaces of the horizontal type thermal CVD device.

Title: Method and apparatus for controlling thickness of parison
Inventor: KANAZAWA SATOSHI
IPC: B29C49/78
Filed: 1993-04-26
Abstract: PURPOSE:To distribute a predetermined thickness in a parison having a partly varied thickness by reducing a pressing force during moving of an inner core during molding, moving it to a predetermined position, and then pressing the parison by a pressing pressure specified after the movement. CONSTITUTION:An injection hydraulic cylinder 1 is detected at its extruding pressure by a molten resin extruding pressure detector, input at the pressure to a parison program controller 10, and its command is controlled through an injection pressure regulator 7. On the other hand, an inner core 5 is relatively vertically moved to a die ring 6, detected at its position by an inner core position detector 3, and moved at its position by a command of the controller 10. The extruding pressure for moving the core 5 to a predetermined position during molding is lowered, and the parison is extruded by a pressing force specified after the core 5 is moved to the predetermined position. Thus, even when a parison having different thicknesses in a vertically circumferential direction is required, the parison having desired thickness structure can be formed.

Title: Mounting method for semiconductor chip
Inventor: WATANABE MAKOTO
IPC: H05K3/32
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability by suppressing production of bubble and increasing the bonding power in the case of mounting a semiconductor chip onto a circuit board through an anisotropic conductive thereby preventing a thermal strain from being developed in the semiconductor chip and the circuit board. SOLUTION: After an anisotropic conductive adhesive 18 is applied onto a circuit board 12, the circuit board 12 is heated temporarily at a temperature lower than the curing temperature of the anisotropic conductive adhesive 18 by means of a heating jig 20. Subsequently, a semiconductor chip 13 is set on the circuit board 12 and thermocompression-bonded by means of a hot press 19 thus curing the anisotropic conductive adhesive 18. Generation of thermal strain can be prevented by heating the circuit board 12 also from the lower surface side at a temperature lower than the heating temperature of the semiconductor chip 13.

Title: Multishaft boring method and its device
Inventor: SANO HIROYUKI
IPC: B23B39/18
Filed: 1995-05-22
Abstract: PURPOSE: To quickly and easily perform work to apply tensile force to a belt related to a change in a boring position by moving a tension pulley according to a movement of respective boring shaft positions by extension-contaction of a cylinder for tension. CONSTITUTION: In order to change a pitch diameter of boring shafts 11 to ϕB from ϕA, bolts 21 fixing slide holders 28 of the respective boring shafts 11 existing in a ϕA position are loosened, and the boring shafts 11 are made freely movable in the direction of long holes 14. The respective boring shafts 11 are moved to a ϕB position by positioning graduations 23 or the like. At this time, since the ϕB position exists in a small diameter position to the ϕA position, tensile force applied to a belt 13 becomes loose. However, since pressure is adjusted in a tension cylinder 22 by a pressure reducing valve 30 so as to become proper tensile force, a tension pulley 15 installed on the tip of the tension cylinder 22 advances, and the tension pulley 15 contacts with the belt 13, and keeps proper tensile force.

Title: Control system for inverter
Inventor: MINAMOTO MASAHIRO
IPC: H02M7/48
Filed: 1982-07-15
Abstract: PURPOSE:To enable to return to the set speed by switching a control mode in response to the lower limit of the operation limit of an inverter and restarting it in a short time after recovery irrespective of the short or long time of a power interruption or the rotating speed of a motor. CONSTITUTION:A frequency command is reduced by a current regulator 24 to constantly control the DC current during the time while the rotating speed of a motor is higher than the lower limit of the operating limit of the inverter at the instantaneously stopping time. When the power interruption time is prolonged or the deceleration of the rotating speed is early so that the frequency of the inverter becomes lower than the operating limit frequency fmin or lower, a logic arithmetic unit 30 is operated to interrupt the flow of a signal from a V/F converter 17 to a ring counter 18, thereby stopping the operation of the ring counter 18. Thus, the inverter is stopped, and the generating operation of the motor 5 is stopped, and the DC current Idc of the inverter becomes zero. This is continued from the time when the frequency of the inverter becomes lower than fmin to the recovery time.

Inventor: YAMADA MINORU
IPC: G03D3/00
Filed: 1989-05-16
Abstract: PURPOSE:To suppress the generation of silver staining and to facilitate the maintenance of developing apparatus by disposing a metal having the larger tendency to ionization than silver in a position where the metal is capable of coming into contact with a developing soln. separately from the constituting members of a developing tank. CONSTITUTION:The metal which is installed separately from the constituting members of the developing tank and has the higher tendency to ionization than the silver disposed in the developing tank is brought into contact with the developing soln. at the time of the development processing of the silver halide photographic sensitive meterial. This metal substitution by which this metal is eluted in the form of metal ions into the developing soln. and in turn the silver ions diluted in the developing soln. are reduced to silver, therefore, takes place and this silver is deposited on the metal. Since a chelate agent is added to the developing soln. in this case, a stable metal chelate compd. is formed by this chelate agent and the adverse influence on the developing soln. by the metal ions is eliminated. The silver staining is lessened in this way and the maintenance of the developing apparatus, such as automatic developing machine, is facilitated.
