Title: Bias circuit for amplifier
Inventor: FUJISAWA MASANORI
IPC: H03F3/30
Filed: 1985-10-16
Abstract: PURPOSE:To reduce number of externally mounted pin number in circuit integration and to obtain a large output voltage by providing a common bias section biasing in common a non-inverting input terminal to a pre-stage amplifier circuit and a post- stage amplifier circuit and a constant current circuit flowing a constant current to a negative feedback resistance of the post-stage amplifier circuit. CONSTITUTION:The common bias section 12 consists of resistors 13, 14 and biases in common a non-inverting input terminal (+) of the preamplifier circuit 10 and a non-inverting input terminal (+) of a main amplifier circuit 11. A negative feedback resistor 15 is inserted between an inverting input terminal (-) of the main amplifier circuit 11 and an output terminal 16 and a constant current circuit 17 comprising a PNP transistor 18, resistors 19 and 20 and supplying a constant current to the negative feedback resistor 15 is provided. Since the non-inverting input terminal of the pre-stage and post-stage amplifier circuits is biased in common, the negative feedback capacitor is saved, and since a constant current flows to the negative feedback resistor of the post-stage amplifier circuit, the DC voltage at the output midpoint is changed from 1/2VCC, a sufficiently larger output voltage is obtained even when a low power source voltage is in use.

Title: Pipeline control system
Inventor: OJIRO YOSHIFUMI
IPC: F17D3/00
Filed: 1982-12-28
Abstract: PURPOSE:To reduce a time increase due to a nullification-control with respect to the small numbers of requirements caused by the small increase of hardwares by returning a process requirement, impossible to effect a normal operation in the pipeline, to a position before the entrance of the pipeline (nullification-control). CONSTITUTION:When no new input is inputted into the pipeline T2 403, no process is effected. When there is an important requirement in the pipeline T2 and a corresponding memory means is busy, it is nullified. When there is the important requirement in the pipeline T2 and the corresponding memory means is idle but a source is busy, it is waited. When there is the important requirement in the pipeline T2 and both of the corresponding memory means and the source are idle, the process requirement is thrown into the source, therefore, the waiting time due to the nullification control may be reduced.

Abstract: PURPOSE:To enhance the wave-length resolution by furnishing a prespectrometer having a narrow incidence slit on the light incoming side of a main spectrometer, forming a spectral image on the surface of an intermediate slit, and widening the width of the intermediate slit. CONSTITUTION:An intermediate slit 1 of a main spectrometer has a wide slit, while a prespectrometer has a narrow incidence slit 5. The light cast from the incidence slit 5 is reflected by a flat mirror, or 6, and the spectra of the pos. and neg. primary diffraction lights are formed on the intermediate slit 1 through a diffraction lattice 7 and a flat mirror 8, and a spectral image is sensed by a photo-sensor 4 through a flat mirror 2 and diffraction lattice 3.

IPC: F24C5/16
Filed: 1983-12-08
Abstract: PURPOSE:To prevent inadvertent burn injuries by showing a pattern on the top plate when the top plate is hot so that is may be made known that the heater is burning. CONSTITUTION:While the top plate 4 shows no pattern under normal temperature conditions, a flower pattern 5 clearly appears on the top plate 4 when the kerosene heater is heated by burning in a chimney.

When the image information equivalent to one page is processed, a print start instruction is given to a print part 17. Thus the picture elements are successively read out of the memory 15 and inputted to the part 16. The part 16 restores a binary image into a multilevel image based on the contents of the binary gradation processing and transfers the multilevel image to the part 17.
