Patent JP-S6231782-A (JP)
Title: Check-valve opening device
Inventor: HATANO MANABU
IPC: F16K15/18
Filed: 1985-08-02
Abstract: PURPOSE:To temporarily release the countercurrent preventing function by a check valve if necessary by installing a diaphragm onto an operating shaft which can advance and retreat so that whose top edge is opposed to the check valve and whose terminal edge projects outside. CONSTITUTION:A diaphragm 14 exists in the first stabilized state where the top edge 12a of an operating shaft 12 is separated from a check valve 1 by the expansion to the atmosphere side and the second stabilized state where the top edge 12a of the operating shaft 12 presses the check valve 1 by the expansion to the primary side of the check valve 1. The shape retaining force in the second stabilized state decreases when the water pressure on the primary side is applied onto the front surface of the diaphragm 14, and the first stabilized state is restored. When the residual pressure in a pipe is discharged for preventing freezing, and the operating shaft 12 is pushed manually, the second stabilized state is generated, and the diaphragm 14 is set into the first stabilized state by the water flow.

IPC: H01L21/285
Filed: 1986-07-23
Abstract: PURPOSE:To obtain a stable contact part of low resistance and improve the quality of a fine semiconductor inteqrated circuit, by making previously the surface of a silicon semiconductor for the contact part amorphous, and forming on the amorphous part an electrode made up of an aluminum wiring containing silicon. CONSTITUTION:On the surface of an silicon semiconductor on which an amorphous layer 10 is formed, an electrode made up of an aluminum wiring 11 containing silicon is formed. After the amorphous layer 10 is formed, the alminum wiring 11 containing silicon is formed without a heat treatment. In the semiconductor integrated circuit, the part to which aluminum containing silicon contacts is made amorphous, so that the crystal growth of silicon contained in aluminum is restrained. Consequently, without using expensive rare metal, and even in the case of a contact hole 9 of small diameter, a stable contact part 71 of low resistance can be obtained by a rather simple process wherein the region for a contact part 71 is previously made amorphous.

Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To enhance the resisting force of a tube to the internal pressure and to avoid the cross flow between channels in the tube by incorporating the hydraulic diameter of a specific range in the channel, and forming the section having a recess zone by inserting a relatively linear part into the channel. SOLUTION: Condensers are opposed, spaced and have entirely parallel headers 10, 12. The headers 10, 12 are preferably welded with a welding seam 19 relative to the header 12. A plurality of tubes 20 are extended between the headers 10 and 12, and communicated with one another. Corrugated fins 34 are disposed between the adjacent tubes 20.

Filed: 1980-12-05
Abstract: PURPOSE: To prevent the generation of variance in the grain sizes, apparent density, etc. of the metallic powder obtained by eliminating the turbulent flow  of the gas blown into a spraying device in producing metallic powder by blowing molten metal flow by means of the spray of high pressure water.  
     CONSTITUTION: Molten metal 2a in a tundish 2 is flowed down through the hole 2b in the bottom part and high pressure water 4a is ejected through a spray nozzle 4 to form water films 4a', by which the molten metal is pulverized to metallic powder at the pulverization point P. In this case, a vortex generator 5 using guide vanes or the like is disposed near the nozzle 4 for high pressure water to generate vortexes in the gas such as air sucked into a spray tank 3, whereby the generation of turbulent flow is prevented and the molten metal flow is dropped correctly at the pulverization point formed by the water films 4a'; therefore, the metallic powder 2a' having less variance in its grain sizes and apparent specific gravity is obtained.

Filed: 1989-07-04
Abstract: PURPOSE:To prevent the rinse process time from being extended by proceeding to the next water feed process and by performing the rinsing with a long balanced control stream time when unbalance occurs in the rinse process. CONSTITUTION:A microcomputer 13 judges whether the water feed/wash process is completed in the step 21 and starts the rinse process in the step 22 if it judges that the step 21 is completed. It judges whether the first drainage/intermittent dehydration/intermediate dehydration process is completed in the step 23. If it judges that the step 23 is completed, it judges whether the water feed/rinse I process is completed. If the intermediate dehydration process is not completed in the step 23, it proceeds to the step 25 and judges whether unbalance occurs. If it judges that unbalance occurs, it proceeds to the step 26 even if the intermediate dehydration process is not completed in the step 23. If it judges that the water feed/rinse I' process with a long balanced control stream time is completed in the step 26, it proceeds to the next process in the step 27.

Title: Incoming branch amplifier circuit
Inventor: MAKINO MASAMI
IPC: H04N5/00
Filed: 1990-06-28
Abstract: PURPOSE:To decrease number of terminal equipments which cannot send a branched input signal when the branched input signal is interrupted by changing over a switch provided between a host mixer and a subordinate mixer so as to interrupt the branched input signal individually. CONSTITUTION:Switches 9, 12 are provided between plural subordinate mixers 5a, 6a mixing branched input signals and a host mixer 15a mixing output signals of the subordinate mixer. Each branched input signal inputted to incoming branch input terminals 1, 2 and incoming branch input terminals 3, 4 is individually interrupted by changing over the switches 9, 12. Thus, only the branched input signal of a circuit in which incoming confluent noise or the like takes place is interrupted without interrupting all branched input signals inputted to the incoming branch input terminals 1-4. Thus, number of terminal equipments unable to send the branched input signal is reduced.

IPC: H04L12/50
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To eliminate necessity for re-calling, owing to a busy line by measuring the working load state of a communication system for providing service and changing a time till response to calling received from a communication line, in accordance with the change in the load state. SOLUTION: A load state-measuring part 13 normally reports a percent value with respect to the max. processing ability of a service processing part 12 to a response time control means 14. The response time control means 14 reports the response time which is obtained from the received percent value by a fixed time interval to a communication control part 11. The communication control part 11 periodically sets updating by the response time and executes response by waiting the passage of the response time which is set in the communication line which receives calling, when calling is received with the communication lines 2a, 2b,....  Therefore, a user who calls a personal communication system 1 can recognize the load state of the personal communication system 1 by the time interval from calling to response, so that a handling time for re-calling owing to the disconnection of the communication line is saved, even when a load is increased.
