Title: Method for quality judgement of welded product by frictional welding and its apparatus
Inventor: MAEHARA KAZUO
IPC: G01N19/04
Filed: 1980-07-16
Abstract: PURPOSE: To judge the quality of welded portions during the course of welding process without any inspection process, by measuring the maximum stopping acceleration at the time of frictional movement stopping in the process of frictional welding.  
     CONSTITUTION: The stopping acceleration of frictional movement becomes the main factor of occurrences of inferior welded products. Because of this, for example, a rotary shaft 4 of a frictional welding machine is connected to a mass body 41 with a flexible part 42, and a strain gage 43 is sticked on the flexible part 42. In this way, the stopping acceleration can be obtained, because, when the rotary shaft 4 stops, the movement of the mass body 41 is delayed due to the acceleration, the part 42 is bent, and the degree of bending is proportional to the strength of the stopping acceleration. When this value is smaller than a previously set value, the product is judged as inferior.

Title: Vapor growth method
Inventor: NARITA SATOYASU
IPC: H01L21/205
Filed: 1994-05-11
Abstract: PURPOSE:To reduce the consumption of a raw material at the time of vapor growth by sufficiently diminishing the raw material flowing on a vent line not used for growth until growth and controlling the raw material at a specified flow rate required for growth several min before usage. CONSTITUTION:A PH3 gas is made to flow to prevent the desorption of P from an InP substrate 1 at the time of a temperature rise at first. The flow rate of trimethyl indium TM-1-2 is increased gradually to a constant quantity at the time of growth several minutes before the growth of an InP buffer layer 2. After the temperature rise time is up, a reaction furnace is supplied with TM1-2 and PH3, and the InP buffer layer 2 is grown. The raw material of the next InGaAs light absorption layer 3 is set at the flow rate of the raw material of the light absorption layer 3 at several min after the completion of the growth of the InP buffer layer 2. The flow rates of TM1 and PH3 are reduced when the light absorption layer 3 begins to grow. Such operation is conducted up to a last InGaAs contact layer 5. Accordingly, the flow rates of raw material gases are sequence-controlled, thus diminishing the consumption of the raw materials at the time of vapor growth, then cutting down manufacturing cost.

Title: Control method of bearing oil film thickness
Inventor: MIYATA YOSHIHIRO
IPC: F04C18/16
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To stably maintain the viscosity of lubricant and thrust bearing oil film thickness by indirectly measuring variation in the bearing oil film thickness from an axial movement. SOLUTION: The thrust bearing oil film thickness is indirectly measured by detecting the axial displacement of projecting rotor by a displacement meter 12. A control valve 10 is operated according to the displacement detected by a displacement meter 12k so that the axial displacement may not move to an oil film thickness reducing direction from a position capable of keeping the required oil film thickness of thrust bearing. Accordingly, the required film thickness can be kept by controlling the axial displacement by changing the temperature of lubrication oil for changing its viscousity.  In this case, it is required to determine a basic position of axial displacement in order to control the axial displacement, and at first the projecting rotor is pushed in to the thrust load direction by a jack or the like to obtain a position where the thrust bearing oil film thickness becomes substantially zero. A position moved from this position to a counter-thrust load direction by a required oil film pressure serves as the basic position.

Title: Method for calculating velocity
Inventor: KURIHARA KATSUMITSU
IPC: G01R23/10
Filed: 1985-05-08
Abstract: PURPOSE:To perform highly accurate velocity detection in both high and low speed areas and to reduce the variation of a time required for making detection, by changing a velocity calculating method depending upon whether the count value of velocity pulses in a fixed time is lower than a reference value or not. CONSTITUTION:Counting of velocity pulses and clock pulses is started at the rise of the velocity pulses and, when the velocity pulses become the N0-th one, the time M0.Tc (Tc is the cycle of the clock pulses) corresponding to the count value M0 of the clock pulses is compared with a reference time T0. When the M0.Tc is larger than the T0, the velocity V of a vehicle is found by using the following equation: V=K.N0/(M0.Tc) (where K is a constant). When the M0.Tc is smaller than the T0, the count value M1 of the clock pulses at the time when the velocity pulses becomes 2N0-th one is obtained and the velocity V of the vehicle is found by using the following equation: V=K.2N0/(M1.Tc).

Title: Door opening and closing mechanism
Inventor: KATO SADAHIKO
IPC: E05C19/16
Filed: 1990-04-16
Abstract: PURPOSE:To automatically open and close a door through simple operation by operating a switching means to engage a clutching mechanism for making the driving force of a motor open and close the door, and disengaging the clutching mechanism for making the manually opening and closing of the door possible when the switching means is not operated. CONSTITUTION:When a switching means is operated as a door is closed, an electric current is applied to a solenoid coil 45 to engage clutching mechanism for transmitting the rotation of a rotor 6 to an output side. The rotor 6 then rotates to rotate an output pinion 40 for transmitting the above rotary motion to a fixed frame 56, and an internal gear 4 is thereby rotatively driven to re lease a latch. When a stopper 17 makes the internal gear 4 impossible in its rotation, namely makes it function as a fixing element, a motor main body is rotated round a shaft 15 to open the door 3. A sensor detects the opening of the door 3 to shut off an electric current. Thus, the door can be opened and closed by only a simple operation, namely pushing the switching means.

In this result, in the case of being no suitable range, alarm is sounded with an alarming device 7 and at the same time, the casting velocity is changed through a casting velocity control device 8 and a pinch roll controlling device 9 to obtain the suitable heat flux. By this method, the surface flaw is prevented and the casting can be stabilized.

Abstract: PURPOSE:To secure safety at a spot in danger of explosion while enabling quick charge in low voltage by connecting an antipolar rectifying element to a secondary cell to enable to charge through no current-limitting resistor at the time of charging. CONSTITUTION:In a diode 5, a cathode is connected to a positive electrode while an anode is connected to an outer connection terminal 3c other than the outer connection terminals 3a and 3b in order ot be antipolar to a secondary cell 1.

Title: Semiconductor device
Inventor: OTSUKA KENICHI
IPC: H01L29/43
Filed: 1992-04-17
Abstract: PURPOSE:To obtain a semiconductor element whose operating voltage is sufficiently low by interposing crystals of copper or silver chalcopyrite denoted as (CuAg) (AlGaIn) (SSeTe)2 or a layer containing a mixture of these crystals between a p-type electrode and a p-type crystal layer. CONSTITUTION:After respective crystal layers 3-10 have been epitaxially grown on a GaAs substrate 1, a CuInSe2 polycrystal layer 15 is formed by vacuum deposition. A polyimide film 13 is formed on the polycrystal layer, and a part of that film is removed. An electrode 14 is formed over it. Since the p-type electrode 14 is connected to the CuInSe2 polycrystal layer 15, it is possible to produce an electrode that has a sufficiently low contact resistance. Moreover, this CuInSe2 polycrystal layer 15 prevents an electrical barrier from being produced between this polycrystal layer and a high concentration p-type ZnSe layer 10. Hence, it becomes possible to reduce a contact resistance associated with the p-type electrode. As a result of this, an operating voltage of a semiconductor element can be reduced.
