Title: Cross head for internal combution engine
Inventor: MATSUMURA NOBORU
IPC: F16C5/00
Filed: 1978-04-06
Abstract: PURPOSE: To improve a loading capacity and to enable pulling-off of a piston without removing a piston bar packing, by locating a screw part at its end, an axis hole having a staged part at an opening side, a coupling bar, a hydraulic piston, a perforation in a cross head pin, and a cross pulg.  
     CONSTITUTION: High pressured oil fed to an oil passage 9 rises an internal pressure in an oil chamber 8, and a coupling bar 3 lengthens as a result of the bar 3 being pressed downward with an oil piston 6. A nut 4 is screwed into a bottom end of the coupling bar 3, and the coupling bar 3 being lengthened is inserted into a cross head pin 2. A piston bar 1 is laid on an abutting surface of the cross head pin 2, and a cross plug 5 is inserted into a perforation 11. As a result of the oil pressure in an oil chamber 8 being released, the coupling bar 3 is going to contract, but refrain from contracting due to the cross plug 5 inserted between the nut 4 and the piston bar 1. And thus, the piston bar 1 is firmly tightened to the cross head pin 2 through the work of the nut 4 and the cross plug 5 due to the elastic force.

Abstract: PURPOSE:To exactly let an operator recognize a fail by storing a fail of an elevator tray and displaying the fail when the tray is selected and a start button is pressed. CONSTITUTION:The control portion of an elevator mechanism 11 for lifting an elevator tray 3 up to a fixed level includes a nonvolatile memory 15e for storing a fail of the elevator tray 3. If a fail of the elevator tray 3 is stored in the memory 15e, when the elevator tray 3 is selected, and a start button is pressed, the control portion 15 outputs a control signal displaying U5 according to the storage of the nonvolatile memory 15e, so that U5 is displayed at the display portion of a console 16. When stationary trays 1, 2 are selected instead of the elevator tray 3, U5 is not displayed, and a normal copy operation is performed.

Title: Hst hydraulic traveling driving device
Inventor: OKUI HISAO
IPC: F16H61/4043
Filed: 1993-03-01
Abstract: PURPOSE:To shorten a time lag when acceleration is carried out from inertial running. CONSTITUTION:The front and the rear of a throttle 16, which regulates a driving speed of a tilting cylinder 12 in an oil pressure pump 2, are connected to each other by a by-pass pipeline 30, and a switching valve 31 is arranged between them. A higher pressure is selected between the pressure of a pair of main pipeline 3, 4 by a high pressure selecting valve 33 so as to be led to a pilot pipeline 32 of the switching valve 31. The switching valve 31 is switched to (b) position with interlocking with reduction in the pressure of the main pipelines 3, 4 when inertial running is carried out by opening a by-pass circuit 40, so that oil can flow via the by-pass pipeline 30. When inertial running is switched to acceleration, the switching valve 31 is kept in (b) position until a discharging flow rate of the oil pressure pump 2 increases and a discharging pressure of the oil pressure pump 2 start increasing, so that a driving speed of the tilting cylinder 12 is increased. After discharging pressure of the oil pressure pump 2 is increased, the switching valve 31 is switched to the (a) position and the tilting cylinder 12 is driven at the speed according to the opening of the throttle 16.

IPC: H01L21/607
Filed: 1987-02-25
Abstract: PURPOSE:To perform bonding readily without generating a leaking current, by bonding a ball to a first bonding pad in the first bonding, heating the insulating coating of a piece of insulating coating wire to a fluid state in the second bonding, and bonding the conductive material to a second bonding pad. CONSTITUTION:Balls 7 are formed without melting of an insulating coating 2 in the first, third,... bondings. The balls 7 are bonded to a first bonding pad 18, a third bonding pad,....

Title: Production in optical fiber preform
Inventor: NISHIOKA KOHEI
IPC: G02B6/00
Filed: 1994-02-15
Abstract: PURPOSE:To produce an optical fiber preform capable of effectively utilizing a soot deposited body by extremely preventing influence of a heating furnace on an upper dummy rod. CONSTITUTION:This method for producing an optical fiber preform comprises gradually inserting a soot deposited body having at least upper end supported by dummy and sintering and vitrifying the soot. In this method, the optical fiber preform is produced by providing a means 17 for preventing increase in temperature of an upper dummy rod 2 on the upper dummy rod 2a side inserted into a heating furnace 14 of the soot deposited body and sintering the soot deposited body. This means 17 for preventing increase in temperature of the upper dummy rod 2a enables a part close to the upper end of the soot deposited body 1 to deeply feed to the center part of the heating part and as a result, damage of the upper dummy rod 2a is prevented and a part close to the upper end of the soot deposited body is also effectively vitrified.

Title: Small crystal resonator
Inventor: SAOTOME KENTARO
IPC: H03H9/02
Filed: 1990-02-21
Abstract: PURPOSE:To obtain the height of frequency stability without dispersing a dispersed substance consisting of metallic powder from weight film into a case by means of the adhesion of the dispersed substance to a metallic film having high affinity with the metallic dispersed substance by forming the metallic film on a position from which the dispersed substance may be dispersed into the case. CONSTITUTION:The case 2 and a cover 3 between which sealing materials 4 are held are heated in vacuum or an inert gas atmosphere of nitrogen or the like and the sealing materials 4 are melted to join and stick both the case 2 and cover 3 with each other. The weight films 5 act as the load mass of vibration to an oscillation chip 1. When a part of the films 5 is irradiated with laser beams through the cover 3 after sticking the cover 3 to the case 2 and dispersed as metallic powder 7, the load mass is reduced and the frequency of the chip 1 can be increased. Thus, the frequency of the chip 1 can be matched with a prescribed reference value by repeatedly dispersing the metallic powder from the films 5 in each fine quantity and measuring the frequency. Since the metallic film 6 having high affinity with the dispersed metallic powder to stick and hold it is formed on the inside bottom 2' of the case 2, the dispersed substance is not dispersed into the case 2.

IPC: H03G5/24
Filed: 1992-02-27
Abstract: PURPOSE:To prevent the degree of clearness from being lowered in the case of audio signals and to eliminate unnaturality by switching the enlargement processing of stereo feelings when input signals are audio signals. CONSTITUTION:It is judged by a judging circuit 15 whether input signals from input terminals 1 and 2 are audio signals or non-audio signals and when input signals MLt and MRt are non-audio signals, the ratio of addition at adders 13 and 14 is controlled so as to enlarge that ratio of FIR filters 7, 8, 9 and 10. When those input signals are audio signals, the adders 13 and 14 are controlled so as to reduce the output signals of the FIR filters. Thus, since the ratio of addition of adding means is controlled so as to enlarge the output signals of arithmetic means in the case of non-audio input signals or to reduce them in the case of audio signals, the stereo feelings are increased in the case of non-audio signals, and the reduction of clearness with the blurring or the degradation of sound quality is suppressed in the case of audio signals as the form of normal reproduction.
