Abstract: PURPOSE:To improve durability of a detecting member and obtain higher responsivity, by supporting elastically an elastic supporting member through a supporting body. CONSTITUTION:The spring constant of a compression spring 13 pressing a block 12 is smaller sufficiently than the spring constant of a spring member 5 supporting a roller 4 and when thickness of a single piece of a ticket P conveyed by a conveying belts 1, 2 is small, a block 12 is pressed for fixing in the position of a fulcrum 14.

Title: Resistance welding control method
Inventor: TAMAI SEIICHIROU
IPC: B23K11/24
Filed: 1980-05-19
Abstract: PURPOSE: To equalize and improve a welding quality, by operating a firing angle of a switching element so that inter-welding electrode voltage exceeds a reference value which has been decided in advance, by one degree at least, in case of spot welding for controlling a welding current.  
     CONSTITUTION: During a constant limited time t 1  from start of power application, it only compares interchip voltage of each cycle and a reference value V 0 . In case when a current has flowed normally, the interchip voltage attains the reference value V 0  after t 2  from start of operation, therefore, in the section of t 2 , welding is performed until power application is finished without performing a changing operation of a firing angle of a switching element such as a thyristor, etc. In case when there is no cycle at all of interchip voltage exceeding V 0  in the section t 1  as shown by a broken line, owing to drop of input voltage, etc., the firing angle is operated by a prescribed extent in the section t 2 . This operation is continuously executed until the interchip voltage attains to V 0 . When it attains to V 0  at the point of Tp,  after Tp, the interchip voltage is monitored, and until it shows a decreasing  tendency, the firing angle is operated in the direction where a current is decreased  by a prescribed extent in order at every cycle.

Title: Image forming device
Inventor: KIMURA MASATOSHI
IPC: G03G15/00
Filed: 1988-03-20
Abstract: PURPOSE:To surely and stably hold a gap between a dielectric drum and a pin electrode by providing a magnet which faces a guiding roller including superconducting substance and provided on both ends of a recording head consisting of the train of pin electrodes and generates magnetic field from both ends of the dielectric drum. CONSTITUTION:The guiding rollers 21a and 21b consisting of the supercon- ducting substance are provided on a roller shaft 20 on both ends of the recording head H consisting of the train of pin electrodes 3. The magnets Ma and Mb are disposed on the dielectric drum 1 side, facing the guiding rollers 21a and 21b. Therefore, as to the superconducting substance of the guiding rollers 21a and 21b, magnetic flux generated from the magnets Ma and Mb can not pass through the superconducting substance because of Meissner effect and the mag netic flux is removed to both ends. The compression of magnetic flux density makes the superconducting guiding rollers 21a and 21b float. The floating am ount is always constant as long as the magnetic field is constant. Thus, the gap between the dielectric drum and the leading edge of the pin electrodes can be always kept constant.

Abstract: PURPOSE:To attain thereafter the conversion of personal names with use of only a basic conversion key and to reduce the operating frequency of a personal conversion key by registering the personal name KANJI (Chinese characters) converted once into a basic dictionary. CONSTITUTION:A dictionary deciding means 61 decides the type of the pointed dictionary part, and a dictionary register means 67 registers the conversion information on a converted 2nd character or character string into a dictionary part different from the pointed one when an inputted 1st character or character string is converted with a certain dictionary part pointed. Thus the conversion information on the converted 2nd character or character string is registered in a dictionary part like a basic dictionary 51, etc., when another dictionary part like a personal name dictionary 52, etc., is pointed and the 1st character string is converted into the 2nd one. When the registered information is converted, it is just required to point the registered dictionary part not the dictionary part pointed at first. As a result, the pointing frequency is reduced to the dictionary part like the dictionary 52, etc.
