Title: Preparation of flexible, electrically conductive film
Inventor: ICHII TAKAO
IPC: H01B13/00
Filed: 1980-08-04
Abstract: PURPOSE:To easily obtain the titled excellent film useful for a flexible printed board, etc. by forming a vacuum-deposited copper film having uniform thickness and little pinhole on the surface of a polymer film by heating copper and a bumping inhibitor in a crucible. CONSTITUTION:Graphite crucible 16 is placed in bottom chamber 5 of chamber 2 of chamber-type continuous vacuum-deposition apparatus 1 kept under high vacuum, and cipper is put into the crucible 16 together with a zirconia particle and a titanium plate as a material for the prevention of bumping, and then subjected to high-frequency induction heating. The copper is molten by heating and the zirconia particle prevents the copper from bumping by sinking and floating near the surface of the molten copper. The titanium melts and also prevents the copper from bumping by trunpping oxygen evolved from the copper. Thus, a vacuum-deposited copper film of uniform thickness is formed on polymer film 8 which is being carried from wind-off roll 9 in a top chamber 4 to wind-up roll 14.

Abstract: PROBLEM TO BE SOLVED: To dynamically perform the increase and decrease of traffic, to avoid data circuit failures and to loosen transmission delay by sending information to that effect when speech information does not reach an input level that is preliminarily set for a time which is preliminarily set. SOLUTION: Data stored in a buffer 4 is stored together with a flag in a buffer 6 after the flag is made into 'one' when a data compressing part 5 detects that speech information does not reach the level that preliminarily set according to an instruction of an information compression controlling part 18. A transmission controlling part 8 adds information that speech data does not reach the input level which is preliminarily set during a time that is preliminarily set according to time length which detects that voice information which is designated by the flag sent from the buffer 6 and the part 18 continues to be in a state in which it is a prescribed level or less. At the time of receiving data, data stored in a buffer 13 is undergone signal processing, etc., in a data expanding part 14 and after that is stored in a buffer 15.

Title: Part fixing equipment
Inventor: ARAI HIDEKAZU
IPC: H05K3/30
Filed: 1985-05-20
Abstract: PURPOSE:To surely fix a part with bending of the leg of a part by engaging a leg bending member thereto at its turning time by providing the leg bending member loosely fittably between the legs of a part and rotatably with the extending direction of the part leg as its axis. CONSTITUTION:The upward force operating on the leg 13a of a part is extremely reduced and the part 13 can be fixed to the substrate surely because the legs 13a, 13a of the part 13 is squeezed by the leg bending members 24a, 25a rotating with its extending direction as the axis, even in case of the leg 13a of the part 13 being short or hard. The dead space in the case of bending the leg does with the small one only, as the width of the leg bending members 24a, 25a only does for the space required by the leg bending members 24a, 25a. It is therefore effective in case of fixing the part having numerous legs and plural parts.

Title: Vibrator support device
Inventor: NAKAMURA KIMIYA
IPC: G01C19/5628
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a vibrator support device, capable of being thinned as a whole with a vibrator supported on a base, and avoiding the touch of hand and application of external forces to the main body part of the vibrator during an assembly operation, etc., thus enabling enhancement of a vibrator protecting function. SOLUTION: A base 25 is provided with a notched part 25a, and a vibrator 11 is supported in air within the notched part 25a. Since the vibrator is set to be almost equal in plate thickness to the base, the vibrator 11 can be stored in the notched part 25a, and the vibrator 11 can be thinned by its plate thickness. Also, since an electrode E at the first end part 11d of the vibrator 11 is on the same plane as the connection 26 of the base 25, the electrode E can easily be connected electrically to the connection 26 by sandwiching a plate- shaped elastic connector 23 between them. Furthermore, since the shape of the connector is also simplified, cost reduction is made possible.

IPC: B66B3/00
Filed: 1990-04-23
Abstract: PURPOSE:To prevent elevator passengers from being confined at a non-stop hall by making effective the registration of only hall call for a specific storey at the time of actuation of a non-stop switch when completion of shutter closing which blockades the specific storey hall, is sensed. CONSTITUTION:If a cage is out of stop, for ex., at the 2nd storey, an HC relay is turned on, and the hall call relay 2H for the 2nd storey and the cage call relay 2C for the 2nd storey can not be turned on. If at this time the shutter of the 2nd storey hall is shut completely, a sensing contact S is closed, and a shutter close sensing relay 2S is turned on through circuitry P-S-2S-N. Even though any person or persons are left in the 2nd storey hall, pushing the 2nd storey hall call button H2 turns on the 2nd storey hall call relay through a circuitry P-H2-2F1-2S1-2H-N, while the relay 2H being turned on is self-held by a circuitry P-2H1-2F1-2S1-2H-N. Thereby the operating circuit causes the cage to reach the 2nd storey to permit the person left to get on this cage and move to other storey.

Filed: 1985-05-20
Abstract: PURPOSE:To make it possible to use a substrate made of an inexpensive raw material in a semiconductor device, by dividing the mounting surface of the substrate into many grooves, thereby absorbing the thermal expansion of a wafer. CONSTITUTION:In this one wafer semiconductor device provided with the functions of a computer, a wafer 3 is bonded to a substrate 1 with a bonding material 4. Aluminum alloy is used for the substrate 1. Many grooves 2 are provided in the mounting surface of the substrate 1. When the size of the surface of the substrate to be divided is made sufficiently smaller (aXa), the amount of displacement of each divided part becomes minute even if large difference in thermal expansion coefficient is present between the wafers to be bonded. Strain due to thermal expansion can be absorbed in some form. Thus separation of the wafer and the substrate, breakdown of the wafer or the like can be prevented. Furthermore, heat radiation is made excellent and the temperature increase in wafer can be suppressed.

Abstract: PURPOSE: To supply fuel mixed with the lubricating oil of a proper mixing ratio all the times by a method wherein a fuel tank is provided together with a lubricating oil tank and the lubricating oil is discharged into the fuel by a pump cooperating with a change of a liquid level of the fuel.  
     CONSTITUTION: When the oil is poured into the lubricating oil tank 4, the oil is filled within a pump 7 through a suction valve 81. When the fuel is poured into a fuel tank 1 under this condition, the pump 7 is operated by an elevation of a float 12 and the oil in the pump is discharged into the fuel by opening a discharging valve 91. When an engine is operated and a liquid level of the fuel in the tank 1 is descended, the float 12 is descended in accompanied therewith and a diaphragm 72 is lifted up through a lever 11, thereby, a pressure in a pump chamber 71 is decreased. Due to the decrease, the discharging valve 91 is closed, the suction valve 81 is opened and the lubricating oil in the tank 4 is sucked into the pump chamber 71 through a suction pipe 8. By suplementing the fuel into the tank 1, the lubricating oil in the pump chamber 71 is discharged again in the same manner.

Filed: 1979-08-24
Abstract: PURPOSE:To obtain the extent of shift alpha of a very little power source dependency, by using two sets of differential amplifying circuits and by using one of them as the bias circuit of the other. CONSTITUTION:Differential amplifying circuit A consisting of MOSFETs 201-209 is the bias circuit of differential amplifying circuit B consisting of MOSFET 213- 219. In circuit A, the threshold voltage of FET205 is lower than that FET204 by alpha1. Since the gate voltage of FET205 and (the threshold voltage of FET204 - the threshold voltage of FET205) are VSS and alpha1 respectively, output Vb of circuit A becomes alpha1. In circuit B, the threshold voltage of FET215 is lower than that of FET214 by alpha. Though VI is compared with VNI for input making VI=VNI true if constant voltage alpha-0, VI is compared with VNI for input making VI=VNI+ alpha true. Since circuit B is used for generation of voltage alpha, power source dependency is very little.
