Filed: 1991-03-20
Abstract: PURPOSE:To improve the detection accuracy of a mode alternate data by providing a means monitoring a time interval for alternate mode publication and a means inverting the alternate mode so as to implement the alternate mode for a prescribed period. CONSTITUTION:A command station 100 publicates an alternate mode in the timing of an oscillator 401 in its own station by allowing a CPU 403 to directly invert the content of a buffer memory 402 in a mode inversion section 103. Command receiving stations 102, 400 receive an alternate mode data for a period inverted by the command station 100, that is, for a period of the oscillator 401. Thus, the alternate mode is publicated to each of the command reception stations 102, 400 for a constant period at all times independently of the transmission processing time of a transmission station, number of transmission stations, information quantity and transmission speed of the network. Thus, it is not required for a mode alternate detection section 108 to detect the mode alternate over a wide frequency and the detection accuracy of the mode alternate data is improved.

Filed: 1984-03-26
Abstract: PURPOSE:To permit to control fuel injection correctly by a method wherein a leak path or a suction path is aligned with the control hole of a cylindrical case intermittently by a solenoid clutch. CONSTITUTION:When the coil 28 of a solenoid clutch 24 is conducted under the discharging stroke of a pump, a clutch plate 25 is attracted to the flange section 27 of a cylindrical case 21, a torque is transmitted to the cylindrical case 21 from a distributing member 1, the cylindrical case 21 is turned against returning members 30, 30 and is stopped by a stopper. Consequently, one end of a control hole 22 is closed by the inner surface of a sleeve 3, therefore, communication between a pressurizig chamber 6 and the leak path 17 is interrupted and pressurized fuel in the pressurizing chamber 6 is sent into a distribution path 15. When the conduction of the coil 28 is intercepted at this time, the clutch plate 25 is separated from the flange section 27 by an elastic supporting member 26, therefore, the pressurizing chamber 6 is communicated with the leak path 17.

Abstract: PROBLEM TO BE SOLVED: To simplify a disposal process such as selection by providing a separating device for separating unnecessary material such as labels from thrown-in plastic containers. SOLUTION: A label is taken off and a mouth part is cut from a plastic container fed to a rotating rotor 19 by a feeding means, by a separating device 17 while pressing to deform the plastic container. The label is scraped by a rotary cutting edge 33 sliding on the surface of the plastic container. Since the mouth part formed harder than the other part cannot be inserted through a clearance between the rotary cutting edge 33 and a fixed cutting edge 59, the mouth part is cut by the rotary cutting edge 33 and the fixed cutting edge 59.  The plastic container, label and mouth part separated by the separating device 17 are dropped into a rear part 1a of a storage box, raked up by a rake-up blade 15b, dropped near an upper part and fed into the front side of the storage box by the inclined face of a guide plate 16, and then fed to the front side in regular order by a feed blade 15a on the front side.

Filed: 1988-03-11
Abstract: PURPOSE:To change the direction of a level detector automatically at all times even if a light receiving element faces in various directions by controlling a level detecting means so that it faces a light emitting element. CONSTITUTION:When light receiving elements 31 and 32 for direction detection receive the signal from the light emitting element and the level detecting means 2 faces the light emitting element, a direction deciding means 3 outputs no instruction to a direction control means 4 and the level detecting means 2 does not swivel. When the light receiving elements 31 and 32 receives the signal from the light emitting element and the level detecting means 2 does not face the light emitting element, the direction deciding means 3 computes the difference between the physical quantities generated when the light receiving elements 31 and 32 receive the signal from the light emitting element by a direction arithmetic part 33 to decide the directions of level detecting means 21 and 22 to the light emitting element. Then a direction control means 4 turns the level detecting means 2 according to the direction judgement of the direction deciding means 3 and controls the direction of the level detecting means 2 to the light emitting element.
