Filed: 1987-08-06
Abstract: PURPOSE:To enable a processing part to carry out a process in parallel with another process by setting an idle receiving state regardless of the working state of the processing part and in case the processing part has its processing margin. CONSTITUTION:A processing part 30 informs an idle state to a receiving state setting means 23 during execution of a certain process and in case the part 30 itself has its processing margin and gives a command to a state information transmitting means 24 to transmit the idle receiving state to the transmitter side.

Title: Apparatus for detecting decomposed gas
Inventor: YAMAUCHI SHIRO
IPC: G01N27/12
Filed: 1985-09-06
Abstract: PURPOSE:To make it possible to detect the internal discharge of electric machinery, by changing the oscillation frequency of an oscillation element by a detection element of which the resistance value changes upon contact with decomposed gas. CONSTITUTION:A solar cell 7 generates predetermined power upon the reception of solar rays and this power is allowed to charge a secondary cell 6. When a switch is closed in this state, a detection element 4 and an oscillation element 5 are driven and the element 5 oscillates a radio wave with predetermined frequency when the insulating gas contacted with the Ag added platinum electrode of the element 4 is normal. This radio wave is received by a receiver 9 through an antenna to be recorded on a recorder 10. When internal discharge is generated in electric machinery 2, gas 3, for example, SF6 gas is decomposed and, when this decomposed gas is contacted with the element 4, the resistance value of the element 5 changes corresponding to the decomposition quantity of SF6 gas. By this method, the internal discharge of the machinery 2 can be detected at an early stage.

CONSTITUTION:A punching metal, after being subjected to drilling work, is passed between rotary drums having wavy form with an arbitrary thickness so as to perform wavy-form work 2 with an arbitrary thickness on the punched metal. In order to obtain a current collecting body having a terminal efficiently, a continuous current collecting body having plate upper parts 1 and plate bottom parts 3 is made by providing alternately unpunched metallic plate parts the width of which are adjusted to the length of the terminal part 1, and unpunched metallic plate parts the width of which are adjusted to the length of the bottom part 3. Next, preferably after an active material is applied to the continuous current collecting body, the metallic plate parts are provided with cuts of the sizes of the terminal part 1 and the bottom part 3 in such a manner that vibrations of cutting or the like are not given to the metallic plate parts as far as possible. Then, a lead paste is applied to thus obtained continuous current collecting body, and the body coated with the lead paste is dried. After that, the joint parts of electrode plates are cut so as to obtain electrodes with a given shape.

Abstract: PURPOSE:To detect the faintness or blur of a drawn line and prevent the break of this line by putting two pressure-sensitive sheets having different levels of sensitivity on each other and sensing the sheet of higher sensitivity at a level higher than the finger contact pressure. CONSTITUTION:A pressure-sensitive drawing pad is made by putting an insulated sheet 15 on a normal heat-sensitive drawing pad containing a resistance sheet 16, a pressure-sensitive sheet 17 and a resistance sheet 18 together with a film switch 10 consisting of a resistance sheet 12, a pressure-sensitive sheet 13 and a resistance sheet 14 and conducts with the finger contact pressure lower than a level sensitive with the normal pressure-sensitive drawing pad. Thus the switch 10 conducts even in such a case where the wiring speed of an input pen is rather high and writing pressure is reduced down to such a level where the sheet 17 does no conduct. Under such conditions, a pen-down state is decided. Then a pen-up state is decided only when both sheets 13 and 17 are not conductive.
