Title: Deposited carrier remover
Inventor: KOMATSU ISAMU
IPC: G03G15/16
Filed: 1979-06-18
Abstract: PURPOSE:To efficiently remove deposited carrier without being affected by the magnetic permeability of the carrier by forming a slender opening which sucks air at the end of the opposing magnetic poles, approaching the end thereof to a recording body and making combination use of magnetic force and suction force. CONSTITUTION:The device is made into the constitution comprising forming a slender opening 6 composed of opposing magnetic pole ends by the respective one ends of magnetic material members 7, 7', closely fitting a nonmagnetic material member 8 to the other ends of these two magnetic material members, inscribing and installing a rotatable bar-form magnet 9 to both magnetic material members 7, 7' and sucking air from one end of a long barrel in the arrow direction at all times. The slender opening 6 is installed in proximity to the surface of the recording body 1 having the toner images and before the toner images are transferred to the recording paper. Thereby, the magnetic force attraction force that affects the deposited magnetic carrier becomes stronger, the removal efficiency may be improved and even the foreign matter, etc. of weak magnetism may be removed because the suction force of air is used in combination.

Title: Facsimile encoder
Inventor: TAKAHARA TORU
IPC: H04N1/417
Filed: 1986-04-01
Abstract: PURPOSE:To shorten a time required for encoding by turning one line full white flag ON when an encoding line is the full white line. CONSTITUTION:When there is no change point in the encoding line, namely, the encoding line is the full white line, a control circuit 3 turns the self- management one line full white flag 5 ON. When the change point address of the encoding line is detected and the change point is not present, the control circuit 3 views the one line full white flag 5 therein. When the one line full white flag 5 is turned ON, since the encoding line and a reference line one line before are full white lines, the control circuit 3 does not detect the change point address but outputs a vertical mode VO to a code converting circuit 4. Thereby, the time required for encoding can be shortened.

Title: Production of gear wheel
Inventor: KISHIMOTO GUNJI
IPC: B21J5/02
Filed: 1985-04-10
Abstract: PURPOSE:To increase the accuracy in gear wheel and to reduce the cost by punching a shaft hole as well as by forming a gear wheel integrally by hot forging, then by moving the wall of the outer peripheral part of the shaft hole in the cold coining stage. CONSTITUTION:An upset blank FW is formed by subjecting to plastic work with hot forging by heating the blank which is cut in the necessary length. The gear profiling face is then formed integrally via one time or plural times of forging stage by fitting the blank FW into the closed forging die. In this case the tooth profile 1 is formed somewhat smaller than the set tooth profile 2. A shaft hole 3 is then made on the blank FW with smaller diameter than the set bore diameter to let the shaft hole part has an excess metal part. A punch 6 is forcibly fitted into the shaft hole 3 in the cold coining stage. With this method the tooth profile 2 is formed by moving the excess metal part 7 of the shaft hole inner peripheral part. The tooth profile flaw in not caused because of no ironing stage being performed. The gear accuracy is therefore increased and the cost reduced as well.

Title: Heat transfer tube for absorber
Inventor: TANAKA HARUO
IPC: F28F1/10
Filed: 1992-02-27
Abstract: PURPOSE:To improve a heat exchanging efficiency by providing a groove in a trough between crests of a plurality of protruding stripes provided longitudinally on an outer surface of a heat transfer tube. CONSTITUTION:Absorption liquid scattered or dropped from an upper tray and adhered to an outer surface of a heat transfer tube 1 is smoothly fed to next trough 4 over a crest 3 of each protruding stripe 2 on the outer surface of the tube 1. A Marangoni convection is generated along the crest 3 and the trough 4, but since a groove 5 continued to a skirt of each stripe 2 through a discontinuously curved surface is provided in the trough 4, liquid film thickness is discontinuously largely different, and hence strengths of the convections at the crest 3 and the trough 4 are remarkably different. Accordingly, the convection generated at the crest 3 and the convection generated at the trough 4 are strongly interfered, and a large disturbance is generated axially of the tube 1. Hence, heat exchange on the outer surface of the tube 1 is expedited. Thus, a heat exchanging efficiency is improved.

Abstract: PURPOSE: To eliminate an auxiliary heat exchanger by mounting a fluid filter, a heating device for fluid and liquid impurities upstream of the filter, a device to by-pass these and by by-passing part of the fluid when generating a specified pressure difference caused by solidification of the liquid impurities by low temperature of the fluid. CONSTITUTION: A heater 12 and a filter 14 are arranged in series, and a by-pass device is placed to by-pass these. During a normal operation whole liquid such as fuel is heated by the heater 12 and then fed to the filter 14 to separate solid impurities. When the temperature of fuel is low, water contained is solidified to form particles of ice, which blocks fuel filter 14 to increase pressure in the duct 16. When the pressure difference reaches a specified limit, the fuel by-passes through relief valve 20 to join downstream of the filter 14 again. The reduced fluid stream is heated by the heater 12 to a temperature sufficiently high to melt the particles of ice blocking the filter 14.

Abstract: PURPOSE: To provide a circuit board with low loss and high signal transmission speed at high frequencies. CONSTITUTION: On a nickel-plated layer 22 which is a magnetic material formed on a copper-plated layer 20, a gold-plated layer 24 which is a non-magnetic material is further formed. Thus when a circuit board is used at high frequencies, though inductance of the nickel-plated layer 22 increases, current flows to the overlying gold-plated layer 24 and to the underlying copper-plated layer 20 due to skin effects, while no current flows to the nickel-plated layer 22 made of the magnetic material located in between, thereby generating no transmission loss due to the nickel-plated layer 22.

Title: Facsimile equipment with inclination correction function and its inclination correction method
Inventor: KUWABARA KENICHI
IPC: G06T3/00
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To correct an inclination on a reception side, which occurs when an original is placed obliquely on a transmission side and when the original itself is diagonally printed. SOLUTION: Coded data from the facsimile equipment 3 of a transmission side, which are received in a reception part 11, are decoded in CODEC 121 of a decoding part 12 and sequentially stored in a plurality of recording line buffers 122 in unit of one line. A correction part 13 sets an arbitrary point on the recording line buffer 122 as a reference point (original point) and obtains a distance and an angle with a pixel. A coordinate before inclination is obtained by setting the distance with the pixel as a radius for the reference point as a center and a new coordinate of the original is obtained by correcting the inclined angle. The obtained coordinate of the pixels is recorded in the recording line buffer 122 after an inclination correction processing. Then, it is transmitted to a thermal head 141. Thus, pixel data whose inclination are corrected are printed on thermosensitive paper.

Filed: 1989-03-28
Abstract: PURPOSE:To eliminate the need for an externally mounted component such as an externally mounted terminal or capacitor and to attain miniaturization by connecting a resistor, a MOSFET and a resistor in series between a power supply and ground, using a connecting point between a drain of a MOSFET and a resistor as an input of inverters of 2-stage connection, connecting the gate of the MOSFET to a power supply, and connecting a back gate to ground. CONSTITUTION:At application of power supply, since a transistor(TR) (MOSFET) M1 is turned off and a voltage VB rises with a power supply voltage VDD as shown in a waveform D. Then a threshold level of an inverter reaches 1/2.VDD and an output Vout goes to a high level. When the power supply voltage VDD sufficiently rises and a TR M1 is turned on, the voltage VB reaches a value R2/R1+R2.VDD set by resistors R1 and R2. The voltage reaches ao inverter threshold level or below and the output Vout goes to a low level, reset is applied automatically at application of power supply. The voltage VB is outputted via a buffer and the output Vout is a reset signal subject to waveform shaping.
