Title: Ac/dc converter
Inventor: TSUNETSUGU YUKIO
IPC: H02M7/217
Filed: 1993-11-01
Abstract: PURPOSE:To provide the AC/DC converter which is sufficiently immune to the rapid increase of a current to flow in a load. CONSTITUTION:An AC voltage VIN is supplied to a diode D1, half rectified and supplied to the collector of an IGBT QM1 (or MOSFET) operated as a main switch element. By controlling a voltage between the gate and emitter of this IGBT QM1 with a control circuit 17 and a booster circuit 18, ON/OFF control is performed. Then, an output voltage provided from the emitter of the IGBT QM 1 is supplied to a series power supply circuit 11, and a DC voltage is outputted. Since the IGBT QM 1 is turned on when the sine half wave of the AC voltage VIN rises and fails, even when the current to flow in a load R to be driven is rapidly increased, the reduction of an output voltage VOUT can be suppressed, and the converter can be sufficiently immune to the rapid increase of the load current.

Title: Odd/even number field discriminating device
Inventor: WATANABE MASAYOSHI
IPC: H04N5/10
Filed: 1986-11-17
Abstract: PURPOSE:To facilitate the evaluation and measurement of a television signal by counting an equivalent pulse before a vertical synchronizing signal in a composite synchronizing signal and using the count value so as to discriminate an odd number field and an even number field thereby ensuring the discrimination of the odd/even number fields. CONSTITUTION:An output of a comparator 1c of a horizontal synchronizing signal detection section 1 is fed to a terminal T of a shift register 3a and an output of an AND gate 2e of a reset signal generating section 2 is fed to a terminal R. A shift register 3a counts an input pulse to reset the shift register 3a. Thus, the shift register 3a counts only an equivalent pulse before a vertical synchronizing signal. With the shift register 3a giving the 7 count output, an output of the shift register 3a is connected to a terminal T of a flip-flop 3a so that the flip-flop 3b may output logical 1 and with the shift register 3a giving the 8th count output, the output of the shift register 3a is connected to a terminal R of the flip-flop 3b so that the flip-flop 3b may output logical 0.

Title: Paper feed mechanism in printer
Inventor: KODA YUTAKA
IPC: B41J13/02
Filed: 1988-10-28
Abstract: PURPOSE:To obtain a stable cut-form feed pitch corresponding to a difference in cut-form thickness and a difference in environment conditions by varying a pressing force of a pressure roller against a platen in a multistage manner. CONSTITUTION:When a cam 6a, a spring hook 7, and a gear 8 are integrally rotated clockwise, a pressure roller 3 is retracted from a platen 1 through an arm 4a. When the cam 6a, the spring hook 7, and the gear 8 are rotated counterclockwise, the cam 6a is separated from the arm 4a, and the pressure roller 3 is depressed toward the platen. Further counterclockwise rotation makes the depressing force larger. The cam 6a, the spring hook 7, and the gear 8 are rotated by a pulse motor 11 through a motor gear 10. The feed pitch of cut-form 12 differs by the thickness of the paper being fed. Therefore, the depressing force of the pressure roller 3 toward the platen 1 is varied in many stages by driving the pulse motor 11.

Title: Image forming method of optical printer
Inventor: KOBAYASHI KAZUO
IPC: G03G17/00
Filed: 1992-10-13
Abstract: PURPOSE:To enable the image formation of a simple process without generating ozone by bringing a dispersion in which pigments are dispersed by using a surfactant and a photosensitive drum provided with a layer having a semiconductor characteristic on the surface, into contact with each other and selectively exposing the contact boundary. CONSTITUTION:The titanium oxide of the photosensitive drum 2 is exposed from the inner side of the drum 2 as image patterns under scanning with an N2 laser beam of a UV light source 1 by a polygon mirror. Holes are generated in valence electron band by photoexcitation when the titanium oxide is irradiated with UV rays of the wavelength shorter than the wavelength of the band gap of the titanium oxide which is an (n) type semiconductor. Since the holes have a strong power, the holes oxidize FPEG which is surfactant incorporated into the pigment dispersion 4 in a pigment cell 3 in contact with the titanium oxide. The oxidized FPEG loses the function as the surfactant and parts successively from the org. pigment surface and, therefore, the hydrophobic org. pigments deposit on the surface of the titanium oxide and the images by the pigments are formed on the photosensitive drum 2.

Title: Data transmission control system
Inventor: TANAKA KENJI
IPC: H04L13/00
Filed: 1985-12-07
Abstract: PURPOSE:To improve the transmission efficiency by storing the oldest unconfirmed state variable and starting or restarting a timer applying response reception supervisory operation every change in the oldest unconfirmed state variable so as to recover the error quickly and to reduce the transmission stop time. CONSTITUTION:A state variable storage section, in response to the result of error detection by an error check section 17, stores the transmission sequence number next to an information (I) frame confirmed newly when the oldest unconfirmed state variable changes as the oldest unconfirmed state variable. A timer control module 7 starts or restarts a timer every time the oldest unconfirmed state variable stored in a state variable storage section 18 is changed. Since a response reception supervisory timer is not started nor restarted every time the information (I) frame is sent, if an RR response or an REJ frame from the reception side B is in error, the timeout timing is quickened and the check point retransmission is executed quickly.
