Title: Magnetic brush device
Inventor: KOBAYASHI MASAHIKO
IPC: G03G15/09
Filed: 1983-06-11
Abstract: PURPOSE:To enhance cleaning performance by installing two magnetic brush rolls adjacent to each other, said rolls each having a main magnetic pole nearest to an image bearing body, different in polarity from each other, and said main magnetic pole on the upstream roll and its adjacent magnetic pole on the downstream side in the same roll being same in polarity. CONSTITUTION:A developer 14 formed into a brush on an upstream sleeve 2 is carried by clockwise rotation of the sleeve 2 and rubs the surface of a photosensitive layer 1a. At that time, since fixed magnets 17, 18 same in polarity and different in magnetic force are arranged, the developer 14 is ready to separate from the sleeve 2. Since a fixed magnet 22 in a downstream sleeve 4 different in polarity from the magnets 17, 18 is arranged, the developer carried from the upstream sleeve 2 is conveyed in a belt-shaped layer to the downstream sleeve 4. The distance D between both sleeves 2, 4 are shortened to improve its conveyability. As a result, cleaning performance is enhanced by improving the flow of the developer.

Title: Driving method for step motor
Inventor: IWAMOTO KOUTA
IPC: H02P8/14
Filed: 1980-07-29
Abstract: PURPOSE:To control a step motor with a simple configuration by calculating the number of pulses for completion of acceleration, starting of deceleration, etc., storing the pulses, and controlling to transfer to next step after the total of the motor driving pulses reaches predetermined numeral at every step. CONSTITUTION:Numeral correlating to the period of a pulse signal corresponding to the rotating speeds of the motor is stored in an ROM5. A CUP1 counts the number of pulses to the completing point of acceleration, starting point of deceleration, finishing point of deceleration, stopping point on the basis of the instructions from an instruction center, and inputs them to the counters 11-14. When a start command is delivered, the CPU1 generates a pulse of the period responsive to the initial speed, supplies it to the motor, and subtracts it from the counters 11-14. When the counter 11 counted up, it transfers to next constant rotating step. When the counters 12-13 are sequentially counted up, it sequentially transfers to the respective next step, and when the counter 14 is counted up, it will stop.

CONSTITUTION:When a burner 25 is ignited, water in a heat exchanger 18 is heated to be turned into steam, which is fed into a radiator 20 through a steam pipe 19 by steam pressure. After heat is exchanged in the radiator 20, the steam is turned into condensate and is fed into a drip pot 23 through a check valve 22. Then the internal pressure in a hot water tank is decreased and the condensate collected in the drip pot 23 is returned to the hot water tank until the tank is nearly full, and then the burner 25 is ignited again, repeating a heating cycle. In a bath circuit, the water in a bathtub 2 is gradually heated up to hot water by a circulation heating. At this time, the operation of a circulating pump 4 is synchronized with that of a burner 25. Another circulating pump is not necessary on the side of an air heating circuit. One circulating pump is enough, so that cost is decreased and noise is reduced in the title apparatus.

Title: Wavelength stabilizing apparatus for semiconductor laser
Inventor: IKEZAWA KATSUYA
IPC: H01S5/068
Filed: 1989-04-25
Abstract: PURPOSE:To increase the wavelength stability by feeding back the output of an OP amplifier having no feedback impedance to an injection current of a semiconductor laser. CONSTITUTION:Light from an LD is collimated in parallel light by a lens L, and is made to branch, by a halfmirror HM, into reflected light for feedback and transmitted light as output light. The light for feedback passes a 1/2lambda plate Z, and is made to branch by a beam splitter PBS. One of the transmitted lights is subjected to signal conversion by a photoelectric conversion device PD1, and input to an amplifier A1. The reflected light by the PBS enters a wavelength selection element E; the power is attenuated in response to wavelength-transmittance characteristics, and subjected to signal conversion by an element PD2. The difference between the output from the Al and the output from the element PD2 is terminated by an impedance; its generated voltage is input to an OP amplifier G0 having no feedback impedance. Based on the fed-back base voltage a driving current flows in the LD.

Title: Transmitter and receiver for acoustic wave
Inventor: TORII TSUNEO
IPC: H04R1/40
Filed: 1984-05-25
Abstract: PURPOSE:To reduce the transmission signal and the reception signal supplied to and from oscillating elements in the peripheral part by connecting a few oscillating elements out of oscillating elements in series in the peripheral part and connecting them to terminals of a trasmitter and receiver. CONSTITUTION:The connection of oscillating elements constituting the transmitter and receiver is different among a center part 8A of the transmitter and receiver, an outside perpheral part 8B near the center part, and an outermost peripheral part 8C. The number of oscillating elements connected in series is increased according as going toward the outside peripheral part. Thus, the transmission signal supplied to oscillating elements in the peripheral part is made smaller than that in the center part in case of transmission, and the reception signal supplied from oscillating elements in the peripheral part is made smaller than that in the center part in case of reception. As the result, the connection for tranmission and the connection for reception are equalized, and the constitution is simple on production and maintenance.
