Title: Manufacture of semiconductor laser
Inventor: YAMAMOTO YUKO
IPC: H01S5/00
Filed: 1992-02-03
Abstract: PURPOSE:To facilitate the control of width and thickness of a light-emitting section by an RIBE technique using a selection mask of SiO2. CONSTITUTION:A double heterostructure 10 is formed on a p-InP substrate by depositing a p-InP buffer layer 2, an active InGaAsP layer 3, and an n-InP cladding layer 4. A light-emitting section is formed into a stripe shape on the double heterostructure using a selection mask 5 of SiO2. Specifically, the light- emitting section is formed by an RIBE technique in which the mask is used to etch in such a manner that the active layer 3 and the cladding layer 4 remain in the shape of a rectangle. After a p-block layer 7 and an n-block layer 6 are formed by MOVPE, the mask 5 is removed and then an n-cap layer 8 is formed by MOVPE. According to this method, the width of the light-emitting section is well controlled, and the growth step is controlled to make a uniform, buried layer.

IPC: F02M39/00
Filed: 1983-02-04
Abstract: PURPOSE:To restrict the volume expansion of a fuel oil as low as feasible to stabilize the fuel injection characteristics by forming a pump mounting casing with aluminum or aluminum alloy as a separate body from a cylinder block, or in some other way. CONSTITUTION:A pump mounting casing 30 is formed with aluminum as a separate body from a cylinder block 1, and is installed beside the cylinder block 1 so as to be properly separated from the side part 1a of the cylinder block 1.

Title: Array scanning method
Inventor: SHIMAZAKI TOORU
IPC: H04N5/335
Filed: 1979-02-16
Abstract: PURPOSE:To enable the scanning with fine pitch, by changing the operating sensitivity of each element of the array in time aging and shifting the center of operating sensitivity continuosly. CONSTITUTION:The operating sensitivity of the image sensor S using ultrasonic oscillators is adjusted with the sensitivity adjusting circuit G provided with each element. Further, the operating sensitivity of the element S corresponding to the respective G of each circuit is changed in time aging by shifting the phase by a given amount with the same pattern. Thus, the sensitivity distribution is caused on the array as broken lines, and it is moved along the direction of arrangement of the element S. The peak of the sensitivity distribution curve corresponds to the main line position of the ultrasonic beam to represent the location of the scanning line. Accordingly, the location of the scanning line is moved accompanied with the movement of the sensitivity distribution curve, which means the scanning toward the arrangement of the array element S. The scanning of array is made with continuous sensitivity adjustment with the circuit G. The scanning of array can be made in fine pitch when the sensitivity adjustment is made stepwise in fine step.

Title: Safety device for integrated circuit
Inventor: JIYASETSUKU KOBUARUSUKII
IPC: G06K19/10
Filed: 1990-01-26
Abstract: PURPOSE: To prevent a latch-up state by providing a means which invalidates the operation of the integrated circuit according to a current flowing between a connection terminal of a substrate and the position of the substrate of the integrated circuit connected to the terminal. CONSTITUTION: When an excessively high potential is applied to a terminal X, diodes D1 and D2 and a transistor(TR) T1 are triggered. A TR T2 becomes conductive through the triggering phenomenon of the TR T1 and its conductivity is used as a signal showing the presence of an abnormal phenomenon. When a current flows through a resistance Rl, the voltage drop triggers a TR T3 which supplies a current to a resistance R2, so a voltage developed at a terminal 17 or in a signal DETH varies from Vss to a voltage relating to the value of the R2 and a current flowing through the R2. Consequently, field effect transistors 21-23 become conductive to induce a potential difference so that a signal DETL becomes zero, thus preventing the latch-up state.

Title: Glossiness measuring apparatus
Inventor: KANO YUKIO
IPC: G01N21/57
Filed: 1991-02-08
Abstract: PURPOSE:To obtain a glossiness measuring apparatus which can output the glossiness corresponding to visual sense regardless of the kinds of paints. CONSTITUTION:A projecting lens 18 projects a brightness pattern 16 on a surface to be measured. A photoelectric conversion element 24 converts the intensity of the reflected light from the surface to be measured into the electric signal. An operating means obtains the maximum value of the changing amount of the light intensity based on the electric signal and corrects the maximum value so that the maximum value becomes small when the maximum light intensity of the maximum light reflected from the surface to be measured is larger than a reference value and the maximum value becomes large when it is smaller than the reference value. Therefore, even if the amount of the reflected light is different based on the surface to be measured, the maximum value is corrected in response to the surface to be measured. Thus, the surface to be measured whose visual sense is equal has the equal glossiness.

Abstract: PURPOSE: To accurately make the thickness change and control the thickness after the thickness change, by interrupting the thickness control action temporarily at the time of the thickness change, and by altering each constant correlatively included in the run-out side thickness and the correction for the screw position.  
     CONSTITUTION: At changing the thickness, the monitoring type automatic thickness controlling mechanism 5 interrupts its control action at the same time as starting the changing action for thickness of the traveling strip in the rolling mill 1. Next, according to the thickness change end signal, a proper part at that moment of the rolled material 2 is trailed; after this part arrives at the position of the thickness meter 4, the aim thickness of the thickness meter is altered to the finishing thickness of the second product. The monitoring type automatic thickness control action for the thickness deviation is restarted depending on the strip's new plastic hardness in the rolling work for the second product, according to a new feedback gain constant. Hereby, the desired thickness control can be carried out for the second product after changing thickness with the optimum responsiveness from an early stage.
