Title: Nonaqueous solvent secondary cell
Inventor: OSAKI TAKAHISA
IPC: H01M10/0567
Filed: 1985-04-19
Abstract: PURPOSE:To obtain a cell with high charge/discharge efficiency and superior charge/discharge characteristic by being composed of a negative electrode comprising light metal, a positive electrode, and an electrolytic solution in which electrolyte is dissolving with a nonaqueous solvent and which contains a vinyl polymer. CONSTITUTION:This cell is composed of a negative electrode comprising light metal, a positive electrode and an electrolytic solution in which electrolyte is dissolving with a nonaqueous solvent and which contains a vinyl polymer. To be desirable, a polymer concentration in the electrolytic solution is usually in the range of 0.1-20g/l. The vinyl polymer concentration, being less than the above-mentioned lower limit value, causes insufficient effect, and on the other hand the concentration, being more than the upper limit value, does not admit an increase in the effect, but causes deterioration of a large current- discharge characteristic.

Title: Detector for speed of fluid
Inventor: HIRAYAMA YOSHIO
IPC: G01P5/12
Filed: 1982-05-14
Abstract: PURPOSE:To eliminate possibility of leakage of a fluid, by holding the temperature around a duct in a value different from the temperature of the fluid and detecting the speed of the fluid on the basis of a function of the temperature differnce between the duct and the fluid. CONSTITUTION:When the fluid in a duct 1 runs in the direction of an arrow A, the quantity of heat generated from a heater 7 is flowed to a fluid 2 through an electric insulator 8 and the duct 1.

Title: Method and apparatus for producing carbonaceous material
Inventor: MOCHIZUKI TOMOTOSHI
IPC: C01B31/02
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To mass-produce a carbonaceous material such as carbon nano-tube by heating carbon granules through current carrying or micro wave up to the sublimation temperature in an inert gas atmosphere and by making sublimated gas aggregate on the surface of a cooler. SOLUTION: Carbon granules 2 are held in a heating furnace 1 in an inert gas atmosphere.

Title: Image-processor and method therefor
Inventor: AOYANAGI TAKESHI
IPC: H04N1/41
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To relieve the load of communication or storage by providing a data conversion means that converts a color image signal, so as to decrease the number of color components of the color image signal and a compression means that compresses the converted color image data to the processor so that a data amount of color image data can be reduced. SOLUTION: C, M, Y, Bk data in 8-bit, each received by an image-processing section are given to an image data conversion section 11, where the data are converted into three colors C1, M2, Y1. The C, M, Y signals among the received C, M, Y, Bk signals are given to adders 11-1-3 respectively. On the other hand, the Bk signal is given to all the adders 11-1-3. Then the sum of the Bk signal and each of the C, M, Y signals from the adders 11-1-3 is outputted as the C1, M2, Y1 signals to an image data compression section. Since the compression is applied to only the 3 color image data, C1, M2, Y1, the data amount which should be processed is reduced.

Abstract: PURPOSE:To float a unit and uniformly propagate the twist-back of the unit by forming a curved passage toward a twisting die as a conveying means, and providing many jet holes on the lower face of this passage as air feed passages. CONSTITUTION:An outer unit 13 guided into a curved passage 32 is floated and run by the spout of the compressed air from many air jet holes 24 provided on a partition plate 31 on the lower face of the curved passage 32 without being brought into contact with the inner face of the partition plate 31 in a curved tube 23, thus the twist-back is uniformly propagated without being disturbed by other objects. When auxiliary rollers 37 are provided at necessary positions, the floating of the outer unit 13 is assisted, the guide is assured, and the necessity for a large compressor to increase the compressed air pressure is reduced even if the unit has a large size. The auxiliary rollers are few in number and have a smaller danger to impair the propagation of the twist-back as compared with roller conveying, and the control is made easier.

IPC: G01N21/35
Filed: 1993-04-09
Abstract: PURPOSE:To provide a method for measuring the hardness of a polymeric material in which a pair of polymeric materials are press fitted to the opposite end faces of an ATR crystal, infrared rays are projected at a predetermined incident angle toward one polymeric material from one end of the crystal, and then the hardness of the crystal is determined based on the spectrum of light emitted from the other end. CONSTITUTION:Polymeric sample materials 13, 14 are polished, on the predetermined end faces thereof, up to surface roughness of 0.2-0.8mum. The polished surfaces are then applied tightly to an ATR crystal 12 while opposing each other and sandwiched by press boards 1, 4. A predetermined fastening pressure is then applied thereto by regulating male screws 19, 11. The fastening pressure is set in the range of 1.9-2.0kg/cm<2>. Subsequently, infrared rays from an infrared light source are passed through a polarization filter to produce a vertically polarized light. Infrared rays hvi thus obtained are then projected to the crystal 12 from one end thereof and the spectrum of reflected light emitted from the other end is measured thus determining the hardness. This method optimizes the roughness and press fitting power of the press fitting faces of the materials 13, 14 and the crystal 12 thus enhancing the accuracy in the determination.

IPC: H04J3/00
Filed: 1995-03-17
Abstract: PURPOSE: To provide a timing controller of high flexibility which is used for a TDMA radio equipment and can deal with the change of delay time of the radio equipment. CONSTITUTION: When the timing output value that decides the level of timing output is inputted to a cyclic register 1 together with the timer value that decides the output timing, a coincidence detection circuit 3 detects the lapse of time equivalent to the timer value since occurrence of a reference timing signal. Thus a coincidence signal is immediately outputted, and a D type flip-flop 4 generates the timing output in response to the timing output value. Furthermore, the contents of the register 1 are shifted by the coincidence signal and the timing output value and the timer value are cyclically updated. Then the timing output received from the flip-flop 4 can perform the TDMA timing control having its level and output timing changing periodically in response to the data on the register 1.
