Title: Bias circuit
Inventor: OGAWA ROKUTARO
IPC: H03K19/086
Filed: 1989-06-14
Abstract: PURPOSE:To make a reference voltage highly stable and to attain ultrahigh speed operation by constituting the bias circuit of the same circuit form as an emitter coupling logic(ECL) circuit operating at ultrahigh speed. CONSTITUTION:A gate circuit GC consists of the ECL and a gate circuit transistor(TR) T3 and a bias circuit TR T11 are turned on off complimentarily when viewing the TRs from a node C, and both the circuits are operated in a direction cancelling the base current. Thus, even when a reference voltage VREF (level of the node C) is fluctuated, the stabilization is implemented quickly and highly stable reference voltage is realized. Thus, the high speed operation required substantially to the ECL circuit is realized.

IPC: H01S3/067
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To diminish the dependence upon temperature by a method in which the difference between the maximum loss and the minimum loss is almost equivalent to the difference between the maximum gain and the minimum gain in the first wavelength region of a gain spectrum while a loss spectrum in almost the same gain spectrum shape contracted in the wavelength axial direction is provided.

Title: Image-forming device
Inventor: MISHIMA NOBUHIRO
IPC: G06T3/60
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To reduce image degradation by controlling an arbitrary angle rotating function in accordance with the features of original image data, even when a character image and a photograph image exist mixedly by operating a smoothing means only in the halftone image area of image processed by the arbitrary angle rotating means. SOLUTION: In the case of original on which character images and photographic images (halftone images) mixedly exist, the arbitrary angle rotating function is controlled corresponding to the features of original image data. Image quality is degraded by arbitrary angle rotation, but the degradation in image quality is increased especially in the photograph image and the degradation in image quality is increased with respect to the enlargement of rotation angle. Then, a memory unit part 30 judges whether an input image is a simple binary image or a photographic image, in order to perform smoothing processing to the photographic image and when it is the photographic image, smoothing processing is performed.  Thus, since processing is changed in accordance with the attribute of the input image, the degradation of image quality in the photographic area is reduced and even when the character image and the photographic image exist mixedly, the appearance of original image is enhanced.

Filed: 1977-12-12
Abstract: PURPOSE:To reduce the power consumption and to increase the power supply efficiency, by directly connecting the bias element at the collector potential side of the push pull transistor, and by connecting the bias element at the emitter potential to the intermediate point of the input transformer. CONSTITUTION:The positive power supply is added to the terminal 1 constituting the circuit and the minus power supply is fed to the terminal 2 respectively, and the bias of the circuit is determined with the resistors R2, R3 and diode D1. Further, the signal from the preamplifier AMP is fed to the circuit via the input transformer T1, operating the speaker SP and the collector current and the base current of transistors Q1 and Q2 are increased. However, since the bias resistrors R2 and R3 are directly connected to the base, useless voltage drop is not caused even with the base current increased and the amplification operation is made stable. Accordingly, the bias voltage fed to transistor can be lowered and the power supply efficiency is increased.
