Title: Method of bonding semiconductor chip
Inventor: KASHIWAGI TAKAFUMI
IPC: H01L21/603
Filed: 1993-11-24
Abstract: PURPOSE:To provide a method of thermocompression bonding, capable of eliminating positioning errors that are inherent in conventional thermocompression bonding. CONSTITUTION:A substrate, on which a semiconductor chip fixed preliminarily with an anisotropic conductive sheet, is placed on a stage 1, and it is heated and compressed by a press 2, which is composed of either a metal block heated by pulsating current or a combination of a hot block and a press member.

Title: Check valve
Inventor: YOSHIOKA NAOMI
IPC: F16K15/04
Filed: 1993-11-24
Abstract: PURPOSE:To improve even sealing ability of high pressure fluid by using a polyetheretherketone material for a valve seat and a cermic material for a ball. CONSTITUTION:An easily procured low-cost polyetheretherketone material is used for a valve seat 13 and a ceramic material having high hardness and being difficult to damage and light is used for a ball 14. Through combination of the hardness and the softness, the valve seat 13 is worked as a cushion and the valve seat 13 and the ball 14 re brought into soft contact with each other, whereby the occurrence of wear is reduced. Since through a material is soft, the material is soft against ceramic, a pressure resistance against a high pressure is provided. Further, since the valve seat 13 is formed of a soft material, there is no need for high-grade processing precision and the valve set 13 is adapted itself to the shape of the ball 14, whereby an influence is not exercised by unevenness in processing. This constitution provided a check valve having excellent chemical resistance and sealing ability and handles the valve seat as a consumption good, whereby a labor for a washing work can be eliminated.

Title: Printing paper feeder
Inventor: YOSHIDA YASUNARI
IPC: B41J21/00
Filed: 1990-10-30
Abstract: PURPOSE:To set printing paper on an initial position without the manual operation of the user to improve operability by a method wherein after a power switch is turned off, printing paper is automatically fed to the initial position. CONSTITUTION:When a change-over of a power switch 52 from ON to OFF is detected by a power switch OFF sensor 60 and a paper feed mode is a cut- form paper A, a limit switch 58 is changed over from ON to OFF if cut-form paper A remains on a platen roller 19. The platen roller 19 is driven in a paper discharge direction to discharge the cut-form paper A from a printer 1. When a paper feed mode is a continuous paper mode and a position on which the perforation line of continuous paper B is coincident with the tip end of a paper presser 23 is determined as an initial position, the continuous paper B is discharged until it coincides with the initial position. In this manner, when the power switch 52 is changed over from ON to OFF, power is supplied from a power source circuit 54 to control the position of the cut-form paper A or the continuous paper B to the initial position, and the power supply from the power source circuit 54 is interrupted. Therefore, paper can be set to the initial position at the turn-on of the printer without the manual operation of the user, and the operability is improved.

IPC: F16K31/06
Filed: 1991-10-15
Abstract: PURPOSE:To make the structure of a solenoid valve, in which a filter is mounted on an input port located at a hydraulic circuit connecting part, compact and lightweight, and positively prevent a foreign matter from entering the solenoid valve. CONSTITUTION:A filter 1 mounted on the front end of an outer base 42 (hydraulic circuit connecting part) is constituted by one plate material, a mounting claw 3 is formed on the periphery of the plate material, and plural number of holes 4 penetrating through the plate material are formed on the flat surface except the periphery so as to a network of the holes. The mounting claw 3 of the filter 1 is fitted and mounted in a groove 42f formed at the front end of the outer base 42 utilizing its elastic deformation and without using any other mounting member. Since the size, shape, and arrangement of the plural holes 4 can be set optionally and the size is not changed in use, the passage of a foreign matter to be removed can be positively prevented.

Title: Failure diagnosing method for helicopter
Inventor: NIWA YOSHIYUKI
IPC: G01M99/00
Filed: 1993-10-29
Abstract: PURPOSE:To provide a highly safe failure diagnosing method which makes an excitation device periodically excite an airframe during flight, and detects the resultant vibration of the air frame through an analysis device to judge a failure for making stable diagnosis possible to dispense with overhaul. CONSTITUTION:The vibration characteristics of an airframe 7 can be shown as an amplitude enlarging rate, which is about constant independently of flight conditions. Thus it is proper for the diagnosis of failure to base on the amplitude enlarging rate. The measurement of the amplitude enlarging rate is carried out in such 3 way as an actuator 8 serving as an exciting device is arranged on one of coupling links 6 between a support member 5 and the air frame 7, and excited by a signal issued from a control computer 9 serving as an analysis device. Frequency in this case is different from the frequency of air exciting force, and the frequency in which the amplitude enlarging rate varys greatly is selected. The exciting force and a signal issued from an acceleration sensor 10 are mutually compared, and the amplitude enlarging rate can therefore be obtained. Since the amplitude enlarging rate at a normal time is entirely different from that at she time of failure, the failure can be easily diagnosed.

Title: Apparatus for detecting positional shift quantity of gear
Inventor: HIRAOKA MINORU
IPC: G01B11/00
Filed: 1987-11-24
Abstract: PURPOSE:To accurately calculate the positional shift quantities of two gears, by rotating a gear coated with paint in a meshed state and taking the image of a tooth surface, from which the paint is shaven off by said rotation, by a camera. CONSTITUTION:Paint is applied to the tooth surface of a drive gear 2 while the drive gear 2 is rotated in the state meshed with a drive pinion 1. The paint on the tooth surface of the gear 2 is slid with the tooth surface of the drive pinion 1 by this rotation and the paint 8 of the slid part is shaven off to partially expose the tooth surface of the drive gear 2. The shaven-off part 8a of the paint shows the tooth contact position of both gears 1, 2. Therefore, when the position of the shaven-off part 8a of the paint 8 is calculated, the relative position of the gears 1, 2 can be detected. A camera 4 takes the image of the paint state of the tooth surface of the gear 2 and a microcomputer 6 calculates the positional shift quantity of both gears from the center-of-gravity position of the shaven-off part 8a.

In this case, if a flow rate difference between the theoretical flow rate Qa and the actual flow rate Qa(n) is our of a predetermined allowable error range deltaa, a flow rate coefficient Na(n) is calculated in response to the theoretical flow rate Qa and the control valve 22 and this value is applied in a next time control calculation. With such an arrangement as above, it is always possible to correct the air ratio and the furnace pressure to their proper values.
