Abstract: PURPOSE:To make band gap energy of an active layer in the vicinity of a resonator larger than that of other parts to improve maximum light output of continuous operation by providing a V-shaped or an inversed V-shaped groove along a direction of the resonator in the vicinity of an end face of the resonator of a substrate. CONSTITUTION:A stripe V-shaped groove 21 is formed by means of etching in the vicinity of an end face of a resonator of an n-GaAs substrate 10. At the same time a center part in a direction of the resonator is etched to a depth approximately equal to a bottom of the V-sheped groove 21. A side 22 of the V-shaped groove 21 is approximately similar to a (111) surface. Then an n- InGaAlP clad layer 11, an undoped InGaP active layer 12 and a p-InGaAlP clad layer 13 are formed on the substrate 10. The layer 13 is selectively etched to a middle part with an SiO2 film as a mask to form a stripe mesa part 23. Then an n-GaAs current block layer 14 and a p-GaAs ohmic contact layer 15 are formed to form electrodes 16, 17. Thus band gap energy of a crystal grown on the surface 22 is large.

Filed: 1990-03-30
Abstract: PURPOSE:To prevent the degradation in the accuracy of the patterns formed on an exposing object by moving the exposing object in accordance with the movement of the scale image actually projected via a projecting lens system. CONSTITUTION:A scale 22b to form the scale image moved together with the pattern image of an original picture is provided and the movement of the actual pattern image is detected by detecting the state of this scale image by a photodetecting means 48.

Abstract: PURPOSE:To greatly reduce the amount of HC which is likely to occur in an end zone of flame caused by ignition of an ignition plug by forming an auxiliary chamber in the vicinity of the end zone and effecting self-ignition in the auxiliary chamber after air-fuel mixture is ignited by the ignition plug. CONSTITUTION:An ignition plug 10 is provided in an outer peripheral fringe section of a pent roof type combustion chamber 1 having two inclined faces 1a, 1b and on one end side on a ridge line alpha, and an auxiliary chamber 11 is provided on the other end side.

Abstract: PURPOSE:To provide an image processing method which is capable of automatically specifying necessary portions from the image of an object composed of plural gradations and an image recognizing method using this method. CONSTITUTION:A groove part 40 for welding has an inclination part 42 to be generated by the shape of the curved surface of the tip part of a grinder in addition to a penetration part 44 and a flat part 46. When this image is displayed by a 256 gradation, the image of the penetration part is dark, the image of the flat part is bright and the image of the inclination part changes from a dark part to a bright part. The brightness in the ground part becomes the almost halftone gradation of the penetration part and the flat part. When this image is binarized, a first threshold and a second threshold are provided, the picture elements of the part where gradation is smaller than the first threshold and the part where gradation is larger than the second threshold are displayed as white and the picture elements of the parts where gradation is >=the first threshold and is <= the second threshold are displayed as black. Therefore, the penetration part, the flat part and the end part of the groove part are displayed as white and the ground part 48 is displayed as black.

Title: Optical multiway switch of two-wavelength system
Inventor: SENUMA TAKEO
IPC: H03K17/968
Filed: 1993-03-19
Abstract: PURPOSE:To provide the optical multiway switch of two-wavelength system which is easily miniaturized and multiplexed by reducing the number of optical fibers to an optical switch part to one and takes out the quantity of light due to the difference of the switch position by two-wavelength optical outputs to output a signal indicating the switch position and has not existed conventionally. CONSTITUTION:Signal light and gate light different by wavelength are outputted from a driving circuit part and pass couplers 7 and 8, and are led to the optical switch part through an optical, fiber 9. Signal light and gate light are converted to parallel rays by a lens 10 and are thrown to a light shielding plate 11. When the light shielding plate 11 having notch parts different by width corresponding to respective switch operation directions is moved in the direction corresponding to one switch operation, signal light and gate light pass the notch part and are reflected by filters 13 and 12, respectively. Reflected light is returned to the original optical fiber, and reflected signal light having the level corresponding to the switch operation direction is held in a latch circuit 22 in an operation circuit part on condition that gate light exceeds a threshold level.

Title: Mold for centrifugal casting
Inventor: KOIZUMI TETSUYA
IPC: B22D13/10
Filed: 1980-06-26
Abstract: PURPOSE: To prevent a mold from cracking in end face and cylindrical end parts by providing a projecting or hollow part in order to form the shape of the end face of a mold for centrifugal casting in such a manner that a step part positions within the 1st molten metal layer forming an outside layer part without forming the same to a smooth surface alone.  
     CONSTITUTION: A step part 10 is provided to the sand mold 3 of an end part mold formed to an end plate 2, and a projecting part 9 of a disc shape is provided in an inside direction. When the 1st molten metal 4 is teemed into this mold, the outside circumferential face and end faces solidify and shrink, thereby producing clearances 7, 8. On the other hand, the step part 10 provided to the part 9 also solidifies and shinks, but the direction of the shrinkage is in an arrow direction, and abuts on and is confined by the step part 10 of the sand mold; therefore, no clearances are porduced. Since this prevents flux or the like from infiltering to the outside circumferential side in the inner part, the clearances 7, 8 remain vacant, and no differences in the rates of cooling are caused. A sound cylindrical body or circular columnar body is produced without hot cracking, and uneven microstructures.

Abstract: PURPOSE: To eliminate unevenness of an air-fuel ratio in the above described carburetor in which open-close operation of a secondary side throttle valve is performed by actuators jointly introduced with both negative pressures of venturi at primary and secondary sides, by providing a pair of actuators in both ends of a cylinder row.  
     CONSTITUTION: There are arranged in both ends of a cylinder row a pair of actuators 15 in which a negative pressure chamber 15a is communicated through a negative pressure passage 16 to both a primary and secondary side venturi 1a and 7a further a diaphragm 15b is connected to a secondary side throttle lever 14 through a rod 17. When speed of an engine is increased to increase flow speed of air further increase negative pressure in the vicinity of the venturi 1a, the actuator 15 operates to give a right turning motion in the drawing to a throttle shaft 12 and increase the opening degree of each secondary side throttle valve 13. Accordingly, negative pressure in the vicinity of the venturi 7a gradually increases to additionally feed an optimum amount of mixture to each cylinder. In this way, friction resistance arising from cantilever state turning motion of the throttle shaft 12 is eliminated to very smoothly perform open-close operation of the secondary side throttle valve 13.

Title: Checking method for stand-by ram

IPC: G06F1/00
Filed: 1985-04-22
Abstract: PURPOSE:To avoid erroneous discrimination by writing data and its complement in the first half and the latter of an area simultaneously and inverting contents of the first half or the latter read out at the check time and comparing contents of the first half and the latter with each other to discriminate normality or abnormality. CONSTITUTION:Data M1, M2... are written with complements M1', M2'... on addresses 80H, 81H... of a stand-by RAM. When this RAM is checked, data is read out by the start address 80H and is stored in an accumulator A, and contents of the accumulator A are copied to an accumulator B, and contents of the accumulator B are inverted. Normality is discriminated in case of A=B, but abnormality is discriminated in case of Anot equal to B. Thus, this checking method is not affected even if clocks are stopped during write to the RAM, and errone ous discrimination is avoided because the comparison between contents of the first half and the inverted value of contents of the latter results in disaccord even if the area is set to all '0' or '1' by a momentary break of power supply or the like.
