Title: Manufacture of copper or copper alloy flat type conductor
Inventor: KOJIMA MANABU
IPC: H01B13/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a flat type conductor excellent in the repeated bending characteristic by rolling a copper or copper alloy round wire into a flat shape, heating it to the prescribed temperature for recrystallization, and performing the cold rolling to obtain the section of flat type. SOLUTION: A copper or copper alloy round wire is rolled into a flat type wire through the cold, two-way rolling, etc., in the vertical direction. The wire is heated in the nitrogen gas of about 100-500 deg.C to re-crystallize the flat type wire. Then, the wire is cold-rolled into the section of flat type. The flat type conductor obtained in this method generates no non-uniform worked structure which is the recrystallized core at low temperature, or it is not softened at low temperature. Thus, excellent repeated bending characteristic is obtained even in the thermal cyclic environment. Because the round wire is rolled into the flat type wire, this working is advantageous in the cost aspect.

Filed: 1989-02-09
Abstract: PURPOSE:To decrease the data redundancy by forming two-stage of ROMs as a timing pulse generating circuit in a circuit having a reference clock and a timing pulse and writing only a change point of the timing pulse to the ROMs. CONSTITUTION:When a pulse is fed to a counter 3 from a reset terminal 2, the count of the counter 3 is zero. When a clock is inputted from a clock input terminal 1, the count of the counter 3 counts up sequentially. A number of a change point of the timing pulse is written in a ROM 4, let the number be 1-q and the other points be '0', then the output of the ROM 4 is as shown in figure c. Data is written so that any of outputs O0-OP of the ROM 5 is '1' with respect to the numbers 1-q in the figure (c), and when the point is '0' in the figure (c), the data is written so that all the outputs O0-OP of the ROM 5 are '0', Thus, the redundancy of the written data is avoided.

Filed: 1982-02-26
Abstract: PURPOSE:To simplify the seal structure by providing two airtight spaces to divide clutch operation oil from mission case lubricating oil in a piston part of a clutch device with an oil pressure cylinder to be used for an autobicycle or the like. CONSTITUTION:An airtight space 48 between the front part of a piston 44 and a partition wall 41 and another airtight space 49 between the partition wall 41 and an oil seal 37 of a cylindrical part 36 are respectively provided.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To store noncondensing gas in a small high pressure storage tank securely, to enable the long term storage of it and to cause no problems with an absorption cycle operation. SOLUTION: Noncondensing gas is stored in a direct storing part 92 and the noncondensing gas is stored simultaneously inside a noncondensing gas secondary storing part 94 at high pressure opening a check valve 98 by the discharging pressure of an absorbing liquid pump P1 applied to an indirect storing part 93. When the pump P1 is stopped, the pressure inside the indirect storing part 93 is decreased opening the check valve 95 and the noncondensing gas is moved from the direct storing part 92 to the indirect storing part 93. At each elapse of predetermined time after stopping the operation, the absorbing liquid pump P1 is driven at high rotational speed and then stopped.  In case of the decrease of air tightness by the decrease of the noncondensing gas pressure by the leakage of absorbing liquid from the noncondensing gas secondary storing part 94, the check valve 98 is closed with good air tightness soon after the check valve 98 is momentarily opened by the high discharging pressure.

Title: Manufacture of film by high molecular weight compound with piezoelectric property
Inventor: YAMADA TAKESHI
IPC: H01L41/45
Filed: 1981-03-06
Abstract: PURPOSE:To manufacture a film with superior properties of piezoelectricity and stability in short time by drawing a vinylidene fluoride polymer film which is heated by high frequency current. CONSTITUTION:The film of polyvinylidene fluoride or the film of copolymer having above 40mol% vinylidene fluoride in the main chain of polymer (e.g. vinylidene fluoride-ethylene trifluoride copolymer) is energized by 1-10GHz high frequency current in 20-40 deg.C atomosphere. After the film itself is caused to generate heat and is simultaneously drawn, the output of high frequency current is raised and sizing treatment is achieved. Then polarization is carried out. Consequently, 100-120 deg.C high temp. treatment and two steps temp. control including 50-70 deg.C and 100-120 deg.C, become unnecessary. Further, the time required for drawing treatment is reduced to one third of the time required in conventional process.

Abstract: PURPOSE:To remove an echo by a simple constitution by extracting an absent component of a transmitted signal at a reception side from a signal generated at the reception side by making use of statistical properties. CONSTITUTION:When signal a1 among the N-number transmitted signals a1, a2...an is transmitted by way of transmitter 7 and hybrid 8, the 1st switches of switches 9  and 16 are closed at the same time.
