Filed: 1988-01-25
Abstract: PURPOSE:To prevent breakdown of a semiconductor element, by providing a mutual terminal shorting mechanism in a connector, and keeping the potential of each terminal of the connector equal when the terminal is not connected. CONSTITUTION:Terminals 4 are contained in a housing 3. A terminal interconnection 2 is a conductor part, which is provided in a housing cover 1. When a connector is not connected, the part 2 is in contact with each terminal 4 by elastic force of each terminal 4. Thus, all terminals are kept at the same potential. As a result, inflow or outflow of a current due to static electricity into or out of semiconductor elements, which are connected to the terminals 4, can be prevented. Thus, breakdown of the semiconductor element is prevented. Each terminal 4 is expanded with a terminal on the male side, and contact with the terminal interconnection 2 is lost. In this way, the intrinsic function of the connector is achieved.

Abstract: PURPOSE:To form wiring and junction using a boundary surface between a single crystal semiconductor surface and an Si oxide, by burying metal silicide which can be used as wiring material and is worked in an arbitrary form, in the boundary between single crystal semiconductor and Si oxide. CONSTITUTION:Since the size of holes on the surface of porous Si 120 is minute, it has crystallizability which bears comparison with the surface of ordinary single crystal silicon 140, and the epitaxial growth of semiconductor single crystal such as Si and GaAs is enabled. On the other hand, metal silicide 130 also can be epitaxially grown on an Si substrate 110, if conditions with respect to the kind of metal, the face orientation of substrate, composition ratio, forming temperature, etc. are arbitrarily selected. After metal silicide 130 is firstly formed on the porous Si 120, it is worked in an arbitrary form, single crystal semiconductor 140 is epitaxially grown in such a manner as to fill the metal silicide 120. Then the porous Si 120 only is selectively subjected to thermal oxidation. Thereby a structure is obtained wherein wiring and metal silicide 230 available for junction material are buried in the boundary region of single crystal semiconductor.

Winding process at the lead conductor-wound part is performed before and after the conductor winding at the wiring jig-matching part. Then, length of formed lead conductors can be variously set up by changing the rotational angle and number of the wiring jigs on formation of the lead conductors.

Filed: 1979-02-14
Abstract: PURPOSE: To stably operate an EL plate driven by a DC pulse voltage for long time by eliminating the DC voltage by connecting a capacitor in series to the EL plate.  
     CONSTITUTION: A battery 6 contained in a watch supplies a current to a counter circuit 7 and also to a voltage raising circuit having a coil 8, a transistor 9 and a diode 10. When a rectangular wave is supplied from a counter circuit 7, a high DC pulse is generated at both terminals of serial circuit of an EL plate 11 and a capacitor 12 by the voltage raising circuit. The capacitor 12 eliminates the DC component of the DC pulse to thus apply only the AC component to the EL plate 11. Thus, the deterioration of light radiation of the EL plate 11 due to DC leakage voltage is eliminated to stably operate the EL plate for long time.

Abstract: PURPOSE:To easily read out many pieces of information by constituting a system for reading out numerical information relating to the control of a copying machine in the order of numerical size only by a single switch even if the numerical information is stored independently of the numerical size. CONSTITUTION:On a console panel 100 in a copying machine, copying magnification is selected by a following method. In case of a fixed magnification, expansion, unmagnification, contraction 1, and contraction 2 are selected in order by a select key 69 and the selected result is displayed respectively on LEDs 81-84. In case of an optional magnification, an input key 70 is depressed at first, and then required magnification is inputted to a RAM 213 by CPUs 1, 201 as an input of 4 digits while checking a display 101 by ten keys 51-60. At that time, the magnification can be changed in each step by magnification up- and down-keys 63, 64. Thus, the four magnification values previously inputted and consisting of four digits in each magnification value are stored in the RAM 213 in the order of address size. When an optional select key 71 is depressed at the time of using the machine, the magnification values are selected in the descending order and displayed on LEDs 85-88, so that respective magnification values can be simply selected only by the single key.

Abstract: PURPOSE:To eliminate the affection of the convection of pressure gas in a heating chamber effectively and permit the holding of temperatures at the upper and lower parts in the heating chamber uniformly at all times by a method wherein the outputs of respective heating sources are unified when a pressure in a furnace is vacuum or normal pressure while the output of the heat source at the side of the lower part is increased to obtain a specified output rate when the pressure in the furnace is high. CONSTITUTION:When a pressure in a furnace is vacuum or normal pressure, the outputs of respective heaters 5, 6 are equalized substantially so that the ratio of respective outputs becomes 50% of the whole output respectively. According to this method, a work zone 4 is heated uniformly from the surroundings thereof and a work in the work zone 4 may be heated uniformly from the upper and lower sides thereof. On the other hand, when the pressure in the furnace is increased, the output of the lower heater 6 is increased. When the pressure in the furnace is increased to a degree higher than 100kg/cm<2>, the output of the lower heater 6 is increased to the degree of 85% of the whole of outputs while the output of the upper heater 5 is decreased to the degree of 15% of the whole of outputs. According to this method, the affection of the convection of pressure gas, which is generated when the pressure in the furnace has become high, may be eliminated and a temperature difference between the upper part and the lower part of a heating chamber 3 may be reduced sufficiently.
