Title: Vane type vacuum pump
Inventor: MURAISHI TORU
IPC: F04C25/02
Filed: 1984-12-17
Abstract: PURPOSE:To enable a pump to perform normal displacement action, by providing the second flow path, connecting an inlet port with a rotor internal peripheral part, and equalizing the operating pressure in the inlet port and the rotor internal peripheral part in a condition that a displacement chamber communicates with the inlet port. CONSTITUTION:A pump is constituted such that an inlet port 1b communicates with the internal peripheral part of a rotor 2 through the second flow path 7b in a condition that a displacement chamber a-d communicates with the inlet port 1b. Thereupon, when a side of the inlet port 1b provides its operating pressure higher than that in the side of the internal peripheral part of the rotor 2, gas in the high pressure is allowed to flow into the internal peripheral part of the rotor 2 from the side of the inlet port 1b. As a result, the pump, decreasing the operating pressure between the both inlet port and rotor internal peripheral part to zero and urging a vane 2a to the outside in a diametric direction by its own centrifugal force, is enabled to perform normal displacement action. While the pump, when the operating pressure in an internal peripheral side portion of the rotor 2 increases to a higher value by decreasing a temperature of lubricating oil to a low level, relieves the lubricating oil from the internal peripheral side portion of the rotor 2 to the side of a displacement chamber also in the side of the second flow path 7b, preventing an override of the operating pressure in the internal peripheral side of the rotor 2.

Title: Brake hydraulic pressure controller and brake liquid filling method
Inventor: HOSOI NORIYUKI
IPC: B60T17/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a brake liquid controller and a brake liquid filling method, being unnecessary to connect a drive circuit to a pressure reducing valve when a brake liquid is filled up. SOLUTION: At an air bleeding-brake liquid filling process B2, evacuation takes place from a master cylinder. At this time, since a pressure intensifying control valve and a pressure reducing control valve both are not driven, the pressure reducing control valve alone is in a state of being closed but there is a check valve of zero atmospheric pressure in valve opening pressure, installed in a brake liquid return route, so that the whole brake liquid pressure controller is turned to vacuum.  In succession, when a brake liquid is injected, this brake fluid is not filled up in a part surrounded by the pressure reducing control valve and the check valve and thereby it is kept on the vacuum intact, but actuation of the pressure reducing control valve is carried out in an inspection process (C) to be done later, whereby the brake liquid flows into even in the part kept on the vacuum intact and thus it is filled up with the brake liquid. Thus, when the brake fluid is filled up, there is no need to install a drive circuit, and automatic operations by means of a robot is made possible to be done, and thus operation efficiency is improved in this way.

Title: Memory, dropout detection system for the memory, and dropout detecting method for the memory
Inventor: SATO ICHITARO
IPC: G11C11/413
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the yield and to reduce the manufacturing cost by detecting dropouts due to crystal defects, etc., of a memory and passing the access of the dropout parts by an address control to enable the memory to be apparently processed as a nondefective memory. SOLUTION: After a test pattern is written by a write and read circuit 15, errors are detected by a read and detection circuit 5 according to addresses and addresses other than error object addresses are stored in a storage memory 4. At this time, in an error detection, addresses of a period in which attributions are different are made error object addresses by comparing a read test pattern with a normal test pattern. Then, access is made to be performed with respect to a memory main body 1 by addresses other than the error object addresses. Thus, even though defects are present in the memory, the memory can be apparently processed as a nondefective memory by performing the address control capable of passing the access to the dropout parts in such a manner.

IPC: C09D127/18
Filed: 1986-11-10
Abstract: PURPOSE:To improve running durability and corrosion resistance by projecting the ionized active particles or hydrogen atom ions or hydrogen molecule ions of an org. compd. simultaneously at the time of forming a plasma-polymerized protective film layer consisting of the org. compd. on the surface of a thin ferromagnetic metallic film layer. CONSTITUTION:A polyester film 1 on which the thin ferromagnetic metallic film layer 12 is formed is moved from a stock roll 2 along the peripheral side face of a cylindrical can roll 3. Gaseous monomer of tetrafluoroethylene is introduced from a gas introducing pipe 6 mounted to a treatment vessel 5 into said vessel and a high frequency is impressed thereto by an electrode 7 to effect plasma polymn. The gaseous methane is simultaneously introduced through a gas introducing port 9 into a Kaufmann type ion gun 8 to ionize the monomer gas and to project the ionized active particles to the region of the film 1 where the plasma polymn. progresses. The plasma-polymerized protective film layer 13 is thus formed. The crosslinking degree of the plasma-polymerized protective film is thereby increased and the durability and corrosion resistance of the film are improved to a greater extent.

Patent JP-S63123986-A (JP)
Title: Heat exchanger
Inventor: NAGAO MASASHI
IPC: F25B9/00
Filed: 1986-11-12
Abstract: PURPOSE:To reduce the pressure loss of the heat exchanger and to improve the heat exchange efficiency by subjecting a heat transfer plate to a coating treatment so as to prevent a brazing material from adhering to parts other than the outer peripheral part of the heat transfer plate. CONSTITUTION:When heat transfer tubes 3 are wound spirally on the outer peripheral wall surface of a heat transfer body 11 and heat transfer plates 11a and the heat transfer tubes 3 are subjected to brazing by use of a solder 16, since films coated with a fluororesin are formed at parts other than the outer peripheral parts of the heat transfer plates 11a, the solder 16 does not adhere thereto but adheres only to the outer peripheral parts of the heat transfer plates 11a. As a result, the passing sectional area of a coolant 2 is not reduced and the increase in the pressure loss is prevented. The thickness of the cylindrical soldered part formed on the outer peripheral wall of the heat transfer body 11 is small, the quantity of heat infiltrating into the heat transfer tube 3 via the soldered part from the direction along the temperature gradient of a coolant 4 is reduced, and the heat exchange efficiency of the heat exchanger can be improved.

Title: Vacuum circuit breaker
Inventor: KANEKO EIJI
IPC: H01H33/66
Filed: 1991-10-16
Abstract: PURPOSE:To increase the flowing current even when a sintered material, the main component of which is WC, is used for a contact part of an electrode in a method wherein either of a pair of electrodes is driven to contain a velocity component in the direction different from the turn-on direction of the electrode. CONSTITUTION:A vacuum valve 20 is composed in such a manner that both end opening parts of an insulating tube 2 are airtightly sealed by end plates 3 and 4 so as to form a vacuum container 5 followed by arranging a pair of electrodes 6 and 7 therein in such a way that they can be freely contacted with or separate from each other. Then, a driving device 26 is driven, a movable current carrying shaft 21 is upwardly moved via a link 27, etc., and subsequently when it reaches the location immediately before the electrodes 6 and 7 are brought into contact with each other, a roller 24a of an engaging body 24 provided on a supporting frame body 23 hits and contacted with a contact surface 22a of a protruded part 22 provided on shaft 21. Accordingly, since the electrode 7 moves off the electrode 6 in the sideways direction, the opposing electrode surfaces are pressed and deformed by the protrusion part resulting in the increase in the contact area. Therefore, even when sintered material the main component of which is WC (tungusten carbide) is used, flowing current can be increased.
