Filed: 1979-09-29
Abstract: PURPOSE:To obtain a compact, inexpensive facsimile equipment by reading bits of picture information at every time and performing logical processing of bits at every time. CONSTITUTION:Readout picture information for one main-scanning-directional line is divided by scanner 7 into groups of bits and converted, group by group, by S/P converter 4 in parallel and the output of it is inputted to and stored in mu-CPU1. Similarly, the next one-line picture information, when inputted, is taken out, group, and logically processed together with the previously logic-processed picture information, group by group, and the results are stored in random access memory RAM3. Thus, every time picture information on each line is obtained from scanner 7, logical processing is performed to extract two-line picture information as picture information on one line.

Title: Organic waste water treatment equipment using ozone with electrolysis
Inventor: KATSUKI OSAMU
IPC: C02F1/46
Filed: 1978-10-11
Abstract: PURPOSE: To decompose most part of organic components into gas and to minimize sludge generation, an electrolytic bath with a number of insoluble electrodes is installed contiguously to an ozone oxidizing bath with built-in slanting plates.  
     CONSTITUTION: Original waste water moves from the inlet 1, is distributed by the distribution nozzles 2 and enters the ozone treatment bath 3. The distribution nozzles 7 makes ozone into very fine bubbles to flow up in the bath 3. The original waste water, while flowing down in the bath 3, is acted by slanting plates 4 and effectively contacts ozone, thus forming into ozone-containing water, and enters the electrolytic bath 18 through the connection opening 19. Into the electrolytic bath 18 inserted are a number of elongated, oblong, insoluble electrode plates 14, to which specified voltage is applied. The waste water, while flowing up between the electeodes 4, is electrolyzed and decomposed into gas. The decomposition is considerably accelerated because of ozone that the water contains. Nondecomposed material floats up as scum and is discharged through the tank 19 that separates and stores decomposed material.

Title: Fabrication of current collecting electrode for photovoltaic element
Inventor: NIIKURA SATOSHI
IPC: H01L31/04
Filed: 1994-06-07
Abstract: PURPOSE:To reduce shadow loss by heating a photovoltaic element from the side opposite to the side provided with a current collecting electrode simultaneously with application of pressure thereto thereby decreasing the width of the current electrode. CONSTITUTION:A photovoltaic element 103 is set on a heating board 101 with the surface, opposite to the side provided with a current collecting electrode, directing downward. It is then heated from the side opposite to the light incident surface to soften a conductive adhesive while simultaneously a pressure is applied thereto using a soft resin sheet 105 thus securing a coated wire onto the light incident surface of the photovoltaic element 103. Since only the required part of conductive adhesive applied to a metal wire is softened, the conductive adhesive does not spread excessively. Furthermore, uniform adhesion is realized by means of the resin sheet 105. Preferably, the heating temperature of the conductive adhesive is set in the range higher by 150 deg. than the softening temperature thereof and the spreading of adhesive is suppressed furthermore within this temperature range.

Title: Signal processing system of optical fiber gyro
Inventor: WASHIMI KOICHI
IPC: G01C19/72
Filed: 1992-04-17
Abstract: PURPOSE:To avoid any variation in a drift and a scale factor at the zero point and make a highly accurate measurement achievable by dividing the driving voltage of a phase modulator at a time when an even double higher harmonic wave is equalized to a zero or adjacent even order higher harmonic wave, with a fixed number, thereby setting it down to the driving voltage of the phase modulator. CONSTITUTION:At adjusting time T0, for example, in order to make a double higher harmonic wave into zero, the value of a Bessel function J2 (xsi) in this period is integrated into zero by an integrating circuit 36, and a control circuit 31 a driving voltage V0 of a phase modulator 7 at this time is divided by a constant K=3, thereby seeking a driving voltage V1. This constant K is predetermined as the value of ratio xsi0/xsi1. If doing like this, a modulation factor xsi is settable to the vicinity of 1.8, and the driving voltage of the modulator 7 is reducible and a basic component is enlargeable, thus a double higher harmonic wave at the time of measurement is kept constant and light quantity control over a light emitting element 1 can be done so well. With this constitution, any variation in a drift and a scale factor at off setting by a temperature change is thus avoidable and, what is more, a highly accurate angular rate measurement can be done in this way.

Title: Dielectric substrate
Inventor: MORI KUNIHARU
IPC: H01Q13/08
Filed: 1988-05-23
Abstract: PURPOSE:To reduce the dielectric constant and dielectric loss tangent of a substrate and provide it with sufficient mechanical strength by dissipating, in a thermoplastic resin, polyethylene fibers having an average molecular weight and initial elastic modules each exceeding its own specific value. CONSTITUTION:Polyethylene fibers having an average molecular weight 500,000 or more and an initial tensile elastic modules 500g/denier or more are dissipated in a thermoplastic resin having a melting point 5 deg.C or more less than that of the polyethylene fibers. If the polyethylene fibers have a molecular weight less than 500,000, their initial tensile elastic modules becomes smaller than 500g/denier and the substrate produced therewith would be short of rigidity. By adopting the composition as described above it is possible to reduce sufficiently the dielectric constant and dielectric tangent loss of the substrate produced and confer sufficient mechanical strength to it.

Filed: 1980-09-10
Abstract: PURPOSE: To give a blank material carrying device a function of taking out and putting in the material for the inside of a compression forming die by retreating the chuch that catches the material through using cam mechanism immediately before carrying.  
     CONSTITUTION: When a movable frame 6 of a carrying device moves forward, a chuck pawl 11a reaches the front of a compression forming die 3, and compression formed blank material 29 is pushed out and caught by the chuck pawl 11a. At this point of time, a rotating cam 22 rotates clockwise and a cam holding plate 21 is pushed through link mechanisms 27, 28 to advance a cam assembly body 16. Consequently, a pushing pin 18 is advance to push a chuck sleeve 12, therefore a chuck 9 turns making a pivot 14 a fulcrum. The chuck pawl 11a retreats from the front of the compression forming die 3, and the material 29 is taken out completely. When the backward movement of the movable frame 6 is completed, the rotating cam 22 turns counterclockwise to reteat the assembly body 16. By this way, the chuck 9 is restored to the original state.
