Abstract: PURPOSE:To enable a program to be written on or read from a memory from the outside by providing a selector in the inside of a microcomputer. CONSTITUTION:When an ordinary mode is designated by a mode signal 17, the selector 5 selects a bus so as to perform the delivery of a signal with an external address/data bus 7 to only a CPU 2, and the selector 16 connects a bus 13 for address control signal for the memory 11 to a bus 15 for address control signal from the CPU 2, and connects a data bus 12 to a data bus 14 from the CPU 2. Also, when a memory access mode is set, the selector 5 separates the external address/data bus 7 from the CPU 2, and connects it to the selector 16, and the selector 16 separates the CPU 2 from the memory 11, and connects a bus 10 for address control signal to the bus 13 for address control signal, and connects a data bus 9 to a data bus 12. In such a way, access from the outside to the memory of the microcomputer 1 can be permitted.

Filed: 1984-06-28
Abstract: PURPOSE:To erase locally desired information and to rewrite by separating a storage material coated on a substrate into many storage areas with a heat- insulating band which is provided regularly in the facial direction of the substrate. CONSTITUTION:A disk 1 is obtained by forming a metallic film 3 on a discoid aluminum substrate 2, and a heat-insulating film 5, if necessary, is provided between the aluminum substrate 2 and the metallic film 3. The metalic film is separated circumferentially to ten large storage areas (A0-A9) each having the same area by a heat-insulating band 4 consisting of a heat-insulating resin. Besides, each large storage area is separated radially at regular intervals into ten areas (B0-B9) by the heat-insulating band 4, and separated circumferentially at regular intervals into ten areas (C0-C9). Consequently, small storage areas of a hundred in total are formed in one large storage area. The heat-insulating band 4 has >=10mum width and the depth almost identical to the thickness of the metallic film 3.

IPC: H01L21/8229
Filed: 1982-08-02
Abstract: PURPOSE:To prevent the generation of leakage even when the width of an isolation region is reduced by partially widening the width of a region opposite to the base region of the isolation region. CONSTITUTION:Two lateral type PNP transistors 31, 32 are formed while holding the isolation region 41. The region 41 is narrowed in order to increase the density of a pattern, and there is a danger that emitter wirings 37, 38 are short- circuited. The width of the region 41 is widened partially toward the base regions 31b, 32b in the regions containing sections opposite to the base regions, and the projecting sections 42, 43 of the isolation region are formed. Accordingly, even when the width of the emitter wirings 37, 38 is narrowed by variance on manufacture, the generation of leakage is prevented because the base regions 31b, 32b are covered sufficiently with the projecting sections 37l, 38l of the emitter wirings.

Abstract: PURPOSE:To prevent the generation of engine trouble by allowing the opened port on a directly joined main plate to nearly coincide with the opened ports on a cylinder head and a cylinder and forming the opened port on a subplate interposed between the main plates smaller than each opened port. CONSTITUTION:The opened port 7 of a main plate 3 directly jointed with a cylinder head 1 is allowed to nearly coincide with the opened port 1a of the cylinder head 1, and the opened port 8 of a main plate directly joined with a cylinder 2 is allowed to nearly coincide with the opened port 2a of the cylinder 2, and only the opened port 9 of a subplate 5 inserted between the main plates 3 and 4 is formed smaller than each opened port 7, 8.

IPC: G01R13/30
Filed: 1977-11-10
Abstract: PURPOSE: To enable display of window indicating arbitrary X-coordinate and arbitrary Y-coordinate on a cathode ray tube screen by overlapping on a signal waveform.  
     CONSTITUTION: In a control circuit 1, digital X-coordinates are generated according to the scanning period, and digital Y signal showing the signal waveform is genearted at the same time. Both signals are added to the X- and Y-axis circuits of cathode ray tube through a transducer. When the X-coordinates are scanned from 0 to the maximum value, signals of Y-coordinates showing the signal waveform are forwarded accordingly, so that the signal waveform is displayed in the cathode ray tube. At this time, coincidence signals are sent into the circuit 1 from comparator circuits 7 and 8 with respect to X=X 1  and X=X 2 , respectively. Then, the switch 5 is changed over, and the interval of X 1 <X<X 2  is scanned and is displayed in the window. Thus, the window of coordinates arbitrarily set in the variable memory circuit is displayed on the cathode ray tube, and this window appears to the observer to be overlapped with the signal waveform owing to the afterglow of the cathode ray tube and afterglow of the eye.
