Abstract: PURPOSE:To stabilize electrostatic chargeability and to greatly prolong the life of the developer by melting a mixture essentially composed of a binder resin and magnetic powder, then spraying and cooling the mixture, thereby forming a spherical and robust carrier having excellent surface smoothness. CONSTITUTION:After the carrier material essentially consisting of the binder resin and the magnetic powder is mixed and melted, the mixture is sprayed in the molten state and is cooled by air flow of a relatively low temp., by which the spherical carrier having the high surface smoothness is obtd. The binder resin may be any resins as far as the resins are thermoplastic resins; for example, polystyrene, polychlorostyrene, polyethylene, polypropylene, etc., are used. Fine particles of all ferromagnetic materials are usable as the magnetic material which is another essential component. The grain size of the magnetic powder is usually <=5mum and the content thereof is confined usually to 30-95wt.% of the weight of the carrier. The electrostatic chargeability is thereby stabilized and the life is greatly prolonged.

Title: Vane push-out mechanism in vane type rotary compressor
Inventor: TANAKA HIROSHI
IPC: F04C18/344
Filed: 1986-05-15
Abstract: PURPOSE:To energize a vane member continuously with a proper pressure by executing high pressure spring energizing under an area requiring a high back pressure while performing low pressure pushing through fluid under a low back pressure area. CONSTITUTION:When a vane 19 is retreated more than some degree into a vane groove 18, a compression coil spring 33 applies an energizing force through a holder 34 onto the bottom face of the vane 19. When the vane 19 is projected, the holder 34 contacts against the shoulder portion 38a at the end section of a wide portion 38 so as to block the energizing force against the vane 19. Consequently, under an area where the push back pressure is low, low pressure fluid pushing can be executed thereby the vane can be pushed continuously toward the inner wall face of a cylinder chamber with a proper pressure.

Title: Level converting circuit
Inventor: MASUDA KOUJI
IPC: H03K5/02
Filed: 1979-09-03
Abstract: PURPOSE:To obtain a high-speed level converting circuit, by driving the single- end push-pull output circuit, which receives signals having phases opposite to each other, by the output of the differential transistor circuit which receives the ECL (emitter coupled logic) level. CONSTITUTION:+5V and -5.2V voltages are given to terminals P1 and P7 respectively. When ECL signal A at terminal P4 is ''L'', transistors Q13 and Q14 are turned on and off respectively. At this time, since the current of constant-current transistor Q15 is flowed to resistance R19, the potential of node N1 is lowered, and transistors Q18 and Q19 are turned off. At this time, since the potential of node N2 is high, transistors Q16 and Q17 are turned on, and the ''H'' level is output to output terminal P2. When the ECL level becomes ''H'', transistors Q14 and Q13 are turned on and off respectively, and therefore, transistors Q18 and Q19 are turned on, and the ''L'' level is outputted to output terminal P2.

Title: Carrier signal generating circuit
Inventor: YATSUSU YASUAKI
IPC: H03K7/08
Filed: 1990-05-01
Abstract: PURPOSE:To eliminate torque pulsation of a motor by updating a data deciding the level of a carrier signal in every timing when the carrier signal is zero. CONSTITUTION:A CPU 3 judges the necessity of gain correction and its correction quantity independently of the timing of a carrier signal and outputs a data representing the level of the carrier signal to an I/O 4 connecting to a data bus. Since a latch circuit 5 of next stage is latched at the time of starting the signal from an oscillation circuit 1, the data representing the level of the carrier signal is supplied to a D/A converter 6 in a timing when the carrier signal is zero and its output varies. A polarity switching circuit 7 supplies a negative polarity to the output of the D/A converter 6 when the output of a frequency divider circuit 2 is at a low level and supplies the positive polarity to the output of the D/A converter 6 when the output of the frequency divider circuit 2 is at a high level. Thus, the output of the polarity switching circuit 7 is a square wave produced in response to the carrier frequency.

Correction based on a learning value is also executed during cold operation wherein feedback control of an air-fuel ratio is not executed but during the cold operation, a guard is set at a learning value used during idling. However, when it is detected that rich abnormality occurs to a fuel system, setting of the guard to an idle learning value is prohibited and this constitution realizes proper control of an air-fuel ratio through application of sufficient correction of fuel increase.

Abstract: PROBLEM TO BE SOLVED: To obtain a device having low power consumption by providing an inertial rotation step making the rotation with the inertia in the manner of stopping a rotation driving step. SOLUTION: A signal is outputted by a judging device 17 in accordance with the judgement whether a frequency of reproduced signal is in the range slightly narrower than the synchronizing range including the operating margin of a producing device 6 and a whole PLL circuit, or not.
