Title: Output device
Inventor: HOSOTSUBO TOSHIHIKO
IPC: G06F3/12
Filed: 1994-10-31
Abstract: PURPOSE: To reduce the labor for registration and setting common to all output devices in a network by registering register information in a memory in accordance with a transmitted register instruction and transmitting the register instruction and register information to another output device having the address stored in a storage means after this registration. CONSTITUTION: When a command from a host computer 3000 is received or an indication is performed from an operation panel 1501, a printer CPU 12 registers its register information in a RAM 19, a data ROM of a ROM 13, or an external memory 14 based on the register operation. When receiving the register instruction and register information from another LBP 1500 through the host computer 3000, the CPU 12 registers the register information in the RAM 19 or the like in accordance with the received register instruction and transmits the register instruction and register information to another LBP 1500 having the already stored address thereafter.

Title: Automatic paper feeder and paper feeding method
Inventor: NAGAYAMA YUTAKA
IPC: B65H1/12
Filed: 1993-11-19
Abstract: PURPOSE:To carry reliably the tip edge of a separated and carried paper sheet to a prescribed contact point of a pair of carrier rollers by pushing down a pressing plate so that the paper sheet in a bent condition by a guide contacts with a paper feeding roller. CONSTITUTION:Paper sheets loaded on a pressing plate 5 are separated into a single sheet by rotation of a paper feeding roller 4 and a slant face part 25, and are carried along a guide 26. A detecting sensor 27 generates a passing signal according to this carrying operation, and after prescribed time passes, a pressing plate raising-lowering motor 50 rotates inversely by a prescribed quantity, and retreats the pressing plate 5 by a prescribed quantity through a pinion 16 and a rack 8. Thereby, a front end part of the paper sheet is elastically bent by the guide 26 in a condition where a rear end part is supported with the pressing plate 5, and contacts with the paper feeding roller 4 in driving. At this time, the paper sheet is carried while causing a proper slip by frictional force generated by the elasticity between it and the roller 4. Thereby, even if the paper sheet is obliquely fed, it is carried in slipping until the tip edge is adjusted to a contact point of a pair of carrier rollers, and a skew is removed.

Title: Signal suppression circuit
Inventor: IDETA HIROSHI
IPC: H03G11/00
Filed: 1986-12-05
Abstract: PURPOSE:To reduce the fluctuation of an output DC voltage and to make the titled circuit suitable for circuit integration by impressing an input signal to a differential amplifier circuit, fixing an emitter voltage of an emitter follower in response to the control voltage so as to cut off the emitter follower. CONSTITUTION:A DC bias voltage C1 and a signal input V1 are impressed to input terminals 21, 22. A variable voltage source 31 is set so as to give a potential V2 sufficiently lower than the voltage V1 normally. The signal V1 is impressed to bases of transistors (TRs) 15, 16 constituting a differential amplifier via an emitter follower comprising TRs 11, 12. In this case, TRs 13, 14 are cut off. In this case, an output voltage of the variable voltage source 31 is selected to be a voltage V3 sufficiently higher than the voltage V1. Thus, the TRs 11, 12 are cut off. Then, a DC voltage being V3-Vbe is impressed to the bases of the TRs 15, 16 and no signal voltage is applied. As a result, a current being a division of the constant current source 19 divided equally is outputted from output terminals 23, 24 as the sinking current. The output current depends only on the constant current source 19 even either at signal output or at signal suppression as stated above. Thus, the output DC voltage fluctuation is reduced.

Title: Photoelectron integrated circuit
Inventor: TSUJII HIRAAKI
IPC: H01S5/00
Filed: 1988-11-17
Abstract: PURPOSE:To prevent the change of optical output by a method wherein changed of dark currents of photodiodes caused by temperature change are offset each other but by inputting the dark currents of the two photodiodes to the differential input of a differential amplifier. CONSTITUTION:In a semiconductor laser diode(LD) 31, an LD bias current IB determined by the base potential VB of a transistor 48 and a resistor 49 flows. A part of laser rays 32 enters a first photodiode 33. In this diode a current IPD1 flows, in which a dark current ID of the photodiode is added to a monitor current I1 proportional to the output power P. The laser rays 32 do not enter a second photodiode 34, and flowing current IPD2 is only dark current ID. The respective currents IPD1 and IPD2 are input to a differential amplifier constituted of transistors 39, 40. Since the in-phase components of the respective inputs are cancelled in the differential amplifier, the dark currents of the first photodiode 33 and the second photodiode 34 can be offset each other out. As a result, a voltage output proportional to the optical output of laser can be led out between terminals 24, 25.
