Abstract: PURPOSE:To eliminate the bend of an exhaust port reducing exhaust resistance and prevent output from lowering by forming the under-head dimension from the contact face with a sealing gasket of an ignition plug to the square head part for an ignition-plug mounting/removing tool longer. CONSTITUTION:An ignition plug mounting/removing hole 12 consisting of an internal thread hole 12b for screwing the thread part of an ignition plug 13 and an inserting hole 12c for an ignition plug mounting/removing tool is formed in between both exhaust ports of an engine in which two exhaust ports 6a, 6b are provided in one combustion chamber. The under-head dimension L from the contact face 13c with a sealing gasket 14 on the housing part 13b of the ignition plug 13 to the square head part 13d for an ignition plug mounting/ removing tool is made longer so that the square head part 13d is separated from the combustion chamber. Thereby, an exhaust port can be formed into a shape having not many bends, reducing exhaust resistance to prevent output from lowering.

Abstract: PURPOSE:To facilitate the working and at the same time reduce the material cost by a structure wherein the cross sectional figure of a shaft is deformed so as to engage with the through hole of a cam lever and an annular projection is formed on the outer peripheral surface of the shaft so as to fasten the other end of a spring. CONSTITUTION:Because the shasft 5 with D-shaped cross section fits into a D-shaped through hole bored on a cam lever 6, the cam lever 6 is interlockably turned with the turning of the shaft 5. The cam lever 6 is pressed against a metal panel 4 by one end of a spring 7, the other end of which is fastened by the annular porjection 5a of the shaft 5. When the shaft 5 is turned counterclockwise, the cam lever 6 shifts a hammer 2 leftwards while compressing a hammer spring 3. When the shaft 5 is turned further until the engagement of the cam lever 6 and the hammer 2 is released, the hammer 2 shifts rightwards and strikes against a piezo-electric element in an insulating case 1a, resulting in obtaining high tension.

Abstract: PURPOSE:To make it unnecessary to use a memory of large capacity by approximating an original image by a polygon, collecting respective points of the polygon whose corresponding centers exist in circular holes correspondingly to the circular holes and detecting a concentrical symbol based on the collected points. CONSTITUTION:The feature values of respective points of an approximated polygon are calculated. A circle passing a target point and two adjacent points is found out, and only when distances d1, d2 of the side and circular arc of a polygon formed among the three points are less than the prescribed threshold value, the calculated circle is regarded as valid one, the center coordinate value is added to the target point and a vector curvature vector defining the target point as the start point and the center coordinate value of the circle as the end point is found out. The vector whose end point is included within the circle is selected out of the curvature vectors, and only when the prescribed number of vectors satisfying the condition is selected, a circle is approximated by using the start points of the selected vectors and the approximated circle is registered as land. Consequently, the capacity of a memory can be reduced.

Title: Gate circuit
Inventor: YAZAWA NOBUHARU
IPC: H03K17/60
Filed: 1983-05-16
Abstract: PURPOSE:To transmit smoothly an AC signal to an output terminal by using a load of a differential pair gating an analog signal as a double output and cancelling the in-phase component at gate changeover by a differential amplifier of the next stage so as to suppress the DC fluctuation. CONSTITUTION:A potential difference between a control voltage Vc and a reference voltage Vr allows a bias current I set by a transistor (TR)Q5 to flow to the 1st differential amplifier TRs Q1, Q2 or the 2nd differential amplifier TRs Q3, Q4. The part between the base and emitter of TRs Q6, Q7 is utilized as a load of the TRs Q1, Q2 and the Q3, Q4 being the differential pairs. Thus, a base-emitter voltage of the TRs Q6, Q7 becomes VBE=kT/qln(I/2)Is, where I is a bias current of the TRQ5 and Is is a saturated current. In considering an error component DELTAI due to variation of base width of the TRQ5, the result of DELTAVBE=kT/ln(DELTAI/2)/Is is obtained and this value is generated in common to the TRs Q6, Q7. Then, it is an in-phase input to the input of the TRs Q8, Q9 and the input is cancelled equivalently.

Title: Compound semiconductor protective film
Inventor: FUJI TATSUO
IPC: H01L21/316
Filed: 1978-07-17
Abstract: PURPOSE: To obtain very fine grade as well as high insulation characteristics and resistance to chemicals thus avoiding element degradation, by providing, on the surface of a compound semiconductor substrate, a protective film consisting of a thin mixed oxide film that is made of several element oxides which compose the substrate, and a thin metal oxide film that coveres the other film.  
     CONSTITUTION: A thin metal film 2 is vacuum vapour coated on a GaAs substrate 3. The material to be used in this process is such as HfO 2 , Ta 2 O 3 , Nb 2 O 3 , or MoO 2 ,  which remains solid during oxidation treatment, has low vapour pressure, does not  form an alloy with Ga or As as well as does not diffuse into Ga of As. Then the  substrate is treated with high temperature in an O 2  atmosphere to form a mixed  thin film 1 of βGa 2 O 3 -As 2 O 3  between the substrate 3 and the thin film 2. In this  process, the thin film 2 allows O 2  to pass but not As 2 O 3  molecules because they are  large in size. Thus formed thin film 1 becomes very fine, and by means of the  quenching effect, acid proof and alkaline proof characteristics are improved as well as the boundary level density is lowered; thus eliminating degradation of an element in which the film 1 is used.
