Title: Liquid-phase epitaxial growing method
Inventor: KATSUI AKINORI
IPC: H01L21/208
Filed: 1980-08-26
Abstract: PURPOSE: To grow a liquid-phase epitaxial film of good quality having improved uniformity, by covering the surface of a semiconductor single crystal substrate with a melt of another unreactive substance having a low specific gravity before the  liquid phase growing.  
     CONSTITUTION: A substrate 4 is filled into a slider 7, and the slider 7 is then set in a B 2 O 3  melt reservoir tank 8. The temperature of the tank 8 is increased by a heater 1 to melt B 2 O 3 , and the surface of the substrate 4 is covered with the B 2 O 3  melt 8'. The substrate 4 is then transferred quickly under a melt reservoir tank 5.  Most of the melt 8' is removed by the transfer; however, the melt 8' partially  remaining on the surface of the substrate 4 prevents the thermal corrosion (etching)  of the substrate 4 and the volatilization of elements having a high vapor pressure.  The melt 8' covering the substrate 4 transferred just under the tank 5 has a lower specific gravity than that of an In melt 5', leaves the substrate 5 and floats on the  melt 5'. The surface of the substrate 4 is then molten back by the melt 5'. The substrates 4 are then transferred under a melt reservoir tank 6 to cool an In melt 6' containing InP slowly and grow a Thin InP film epitaxially.

Filed: 1982-07-07
Abstract: PURPOSE:To couple easily a laser diode and a single-mode optical fiber with each other and to facilitate work and assembly by making one or both end surface of a self-converging type lens between the two spherical or cylindrical. CONSTITUTION:This coupling system consists of the laser diode 1 having a cylindrical light emission diameter, self-converging type lens 2 whose end surface is spherically, and single-mode optical fiber 3.

In this case, the waist diameter is equal to the diameter of the light wave in the optical fiber 3, so 100% coupling efficiency between the diode 1 and optical fiber 3 is obtained. The spherical end surface of the lens 2 is formed either by polishing or by sticking a hemispherical lens.

Title: Color signal processor
Inventor: MATSUMOTO TOKIKAZU
IPC: H04N9/793
Filed: 1984-06-08
Abstract: PURPOSE:To perform correct automatic chroma control even in case of malfunction of an automatic phase control circuit by demodulating a chrominance signal to two color difference signals after A/D conversion and calculating the amplitude value of a burst signal on a basis of both color difference signals to operate an automatic chroma control circuit. CONSTITUTION:The chrominance signal inputted from a terminal 10 is subjected to variable gain amplification by a variable gain amplifier 11 and is subjected to A/D conversion by an A/D converter 12 and is demodulated to, for example, R-Y and B-Y signals by a demodulator 13. These R-Y and B-Y signals are sent to not only a signal processing part 14 but also an arithmetic circuit 15. If the phase of the carrier generated by an automatic phase control circuit APC is shifted, burst signal components appear only on the B-Y axis. If malfunction occurs in the circuit APC, burst components appear on the R-Y axis and the B- Y axis, and a burst signal level is obtained because the burst signal level is given by vector synthesis of R-Y components and B-Y components. Thus, correct automatic chroma control ACC is possible.

Abstract: PURPOSE:To prevent scattering of toner by setting the potential of a developing roller higher than that of a photosensitive body during the period needed from the time the stoppage of the photosensitive body is instructed until the decision of stoppage. CONSTITUTION:When a process control part 31 stops the output of a motor ON signal, a developing voltage control part 37 controls a developing voltage circuit 38 to instruct it to impress a voltage on the developing roller 6, and sets its potential higher than that of the photosensitive drum 2. A stoppage deciding part 35 discriminates whether a predetermined time has passed or not, and if so, it outputs a photosensitive body stopping signal to the developing voltage control part 37, which controls the developing voltage control circuit 38 to stop the impression of the developing voltage on the developing roller 6. Thus, toner does not attach to the photosensitive drum 2, and therefore it never comes into contact with the developing roller 6, nor carried by the photosensitive drum 2 after a motor is stopped. Consequently, the toner never drops and scatters.

Abstract: PURPOSE:To lower noise and to stabilize output by subjecting at least one terminal of optical fiber terminals to serve as the input and output ports of the optically melted coupler, with which the transmission and reception of light are executed via an air layer, to a return light preventive treatment. CONSTITUTION:The transmission and reception of the light are executed via the air layer with at least one terminal of the optical fiber terminals to serve as the input and output ports of the optically melted coupler 1 formed by working plural optical fibers 3, 4 to a tapered shape and thermally welding the same. The above-mentioned terminal is subjected to the return light preventive treatment. The light which is oscillated from a light emitting element and is reflected at the terminal of the optical fiber is, therefore, scattered in directions exclusive of the forward and backward paths and is prevented from returning to the oscillation source of the light emitting element. The optical communication with the stable output of the low noise is thereby executed.

Filed: 1990-05-10
Abstract: PURPOSE:To secure the overall length of a shape and a quality by measuring the overall length of flatness of a strip by setting the strip to a suspension loop state of nearly no-tension by a slide constraining means in a measuring area. CONSTITUTION:A strip 1 which goes into a flatness measuring area 2 by constraining rolls 3a, 3b; 3e and 3f of slide constraining means 3A, 3B becomes a state being similar to no-tension in the area 2 between each of the means 3A, 3B since tension working from the rear and the front is absorbed. Under this state of no-tension, a loop of a suspension state is formed by elasticity of the strip 1 and gravity. While allowing this strip 1 to form a stable loop, an approximate circle radius (r) in the vicinity of the lowest end of the loop, and a bend radius difference distribution DELTAr in the width direction in the lowest end part of the loop are measured by range finders 4A - 4E and a loop height distribution measuring instrument 5. In such a way, usually, based on the minimum value of ly as a reference, an elongation percentage is derived by the maximum value DELTArmax of DELTAr, and also, the kind of elongation is decided by a generation part of DELTArmax.

Abstract: PURPOSE:To secure face-contact between slide parts by a method in which a pressure-bearing metal consisting of a pair of slide members to be mutually combined with each other at their horizontally and vertically curved faces is attached to the bottom plate of two floating caissons, and the two floating caissons are contacted with each other through the pressure-bearing metal. CONSTITUTION:In the slide member 8 of a pressure-bearing metal 3, one end is attached to the contact face of the bottom plate 4 of a floating caisson 1, the other end is shaped into a circular recession extended horizontally, and a circular recession is also formed in the vertical direction. In a slide part 9, a projection to be matched with the vertical and horizontal circular recessions of the slide member 8 is formed. Both the members 8 and 9 are set by matching their recession and projection with a slight spacing, and the member 9 is temporarily coupled by a shear bolt 13 from a slide plate 10 attached with a bolt 11 to both sides of the part 8. The other end of the member 9 is faced almost in parallel with the end face of the pressure-bearing metal 3' of the counter floating caisson 4'. The face-contact of both the members 8 and 9 can thus be secured by relative sliding to eliminate the local concentration of stress.
