Title: Binarizing device for picture signal
Inventor: KATSUTA YUJI
IPC: H04N1/403
Filed: 1986-09-12
Abstract: PURPOSE:To effectively binarize both two and multiple tone wedge parts when the two and multiple tone wedge parts exist in the same original, by outputting binarized data in accordance with the density of a point to be binarized and the weighted mean density of the surroundings of the point. CONSTITUTION:In the case of a two tone wedge picture, such as a character, etc., with which the density of a point to be binarized and the weighted mean density of the surroundings of the point are largely different from each other, '1' or '0' is forcibly outputted to a terminal 13. Moreover, when the density value of the point to be binarized is smaller than the sum of the weighted mean density value of the surroundings and a prescribed value, but larger than a value obtained by subtracting the prescribed value from the weighted mean density value, the output of a comparator 7 becomes '0' and that of another comparator 8 goes to '1'. In case of a multiple tone wedge picture, such as a photograph, etc., with which the density of a point to be binary coded is close to the weighted mean density value of the surroundings of the point, binarized data are outputted in accordance with the weighted mean density value of the surroundings.

Title: Engine with supercharger
Inventor: MURAMATSU TAKAHIRO
IPC: F02B37/00
Filed: 1987-08-31
Abstract: PURPOSE:To prevent the generation of surge sound caused by sudden closing of an intake throttle valve due to decelerating operation by disposing a valve adapted to close when an engine is in the state of decelerating operation in an air supply passage upstream from a supercharger compressor. CONSTITUTION:Under an ordinary operating condition, a valve mechanism 24 opens an air supply passage 4c upstream from a compressor 10. Under a decelerating condition, when an intake throttle valve 18 is suddenly closed, the rotation of the compressor 10 is kept high immediately after the decelerating operation is started. Accordingly, pressure in an air supply passage 4a between the compressor 10 and the closed intake throttle valve 18 is suddenly increased, so that large change in pressure is caused to generate surge sound. At this time, the valve mechanism 24 closes the air supply passage 4c, so that pressure buildup in the air supply passage 4a is lowered than the conventional pressure buildup to prevent the generation of surge sound.

Filed: 1991-08-28
Abstract: PURPOSE:To provide an abrupt change in carrier concentration to a crystal without changing temperature in an impurity cell, by controlling a flow rate of phosphine while an AlGaInP-based crystal is grown on a GaAs substrate. CONSTITUTION:When an AlGaInP-based crystal with interstice adjusted in alignment within a range of + or -0.1% is grown, a III-group raw material is supplied for a substrate 17 while a given constant temperature is kept in III-group raw material cells 12a to 12c. A V-group element is conducted from a phosphine cylinder 16 through a mass flow controller 15, which controls the flow rate of phosphine, to a thermal decomposition cell 13. Then, phosphorus and hydrogen are produced by the thermal decomposition cell 13 and are supplied to the substrate 17. In this case, carrier concentration in the crystal can be controlled in an optimum conduction even with a constant temperature in an impurity cell 14 by changing the flow rate of the phosphine. Consequently, when a flow rate of the phosphine is changed in a short time, an abrupt change is caused in carrier concentration that has an effect on the crystal growth.

Filed: 1994-08-20
Abstract: PURPOSE: To prevent wrong operation by providing a member being slid while meshing a ring gear and controlling a band belt based on the slide of the sliding member thereby realizing the switching of reproduction mode through a simple structure. CONSTITUTION: When a switching is made from a reproduction state to a review reproduction state, a loading motor is operated to slide a first sliding member 83 thus actuating a brake control means B. Since the brake control means B operates to separate a band brake from a reel base 189, a tape runs reversely when the reel base 189 is rotated reversely thus allowing a review reproduction. At the time of unloading the tape, a reel rotation control means C operates to disable rotation of a rewind reel. Consequently, the rewind reel is not rotated at the time of injecting a cassette and over recording is prevented.

Abstract: PURPOSE:To enable direct measurement of an absolute mirror reflectivity in vertical incidence with a simple operation, by a method wherein a semi-transparent mirror is placed at the center and a photometer is turned therearound to measure intensity of light at specified four points. CONSTITUTION:First, a photometry section P is set at a position P1 and a light incoming window of an integrating sphere 2 is turned to a light source section L to measure light. Then, a semi-transparent mirror BS is removed and the light incoming window of the integrating sphere 2 is turned to the light source section L at a position P2 to measure light. With such as arrangement, an absorption factor of air is determined for light to be measured. Then, the mirror BS is set to measure reflected light from the semi-transparent mirror at a position P4 and a 45 deg. reflection factor of the mirror BS is determined from the results. After the end of this preparation, a sample S is placed to measure light transmitted through the mirror BS at the position P2, and then, reflected light from the mirror BS is measured at a position P3. This simplifies the measurement of a mirror reflectivity in vertical incidence by a specified computation from the photometry values thus obtained.
