Title: Operation structure of friction clutch
Inventor: SUZUKI TAKASHI
IPC: F16D23/12
Filed: 1987-04-07
Abstract: PURPOSE:To obtain both easy 'off-operation' and inexpensive, operation structure by providing both a pressure oil chamber, which is constantly supplied with oil, and a relief circuit to a friction clutch, thus adopting a totally hydraulic operation system in order to reduce the operating physical force. CONSTITUTION:A pressure oil chamber 8 is formed between a driving-side revolving body 2 and a driven-side revolving body 5 in order to operate the main clutch A. A hydraulic pump 9 is connected to this hydraulic chamber 8 via oil passages 1A and 3A, which are formed on the driving-side shaft 1 and the driven-side shaft 3, respectively so that the hydraulic chamber 8 can constantly be supplied with oil. In addition, a relief circuit 17 with a relief valve 16, which automatically relieves the internal pressure of the hydraulic chamber 8 when the main clutch A is turned off, is interposed between the hydraulic pump 9 and the hydraulic chamber 8. Accordingly, even when an operator treads down an operation pedal 14 deeply in order to turn the main clutch A off, he can turn the main clutch A off with a certain, depressing- operation force, or without increasing this depressing-operation force.

Title: Bus arbitration circuit
Inventor: AZUMA TATSUKI
IPC: G06F13/364
Filed: 1990-03-30
Abstract: PURPOSE:To remove the use of useless time at the time of accessing a bus from a CPU and to improve the processing capacity of the bus arbitration circuit by applying a bus request to a specific sequencer which does not correspond to a master when a bus request is not inputted from the master. CONSTITUTION:When none of bus requests BR1 to BRn are inputted, a priority encoder 40 transfers a bus request to a sequencer 500. After checking the input of a bus ground from other sequencers, the sequencer 500 outputs a bus ground BG0. When any one of the bus requests BR1 to BRn is inputted, the encoder 40 immediately aborts the output of the bus ground BG0 to the sequencer 500 and drives the sequencer corresponding to a selected bus request. Thereby, a bus ground is outputted from the sequencer concerned.

Title: Led array
Inventor: KUMAGAI MOTOO
IPC: G03B27/54
Filed: 1984-05-01
Abstract: PURPOSE:To widen an area where high illuminance is obtained because the normal line of a reflecting surface is not positioned neither in a plane containing the optical axis of the LED array and the array direction of LED chips nor in a plane perpendicular to the array direction of the LED chips. CONSTITUTION:The LED array is so constituted that the reflecting surface of a reflecting plate 6B arranged between the LED chips 2 has the normal line positioned neither in the plane containing the optical axis and array direction of the LED chips nor in the plane perpendicular to the array direction of the LED chips. In this case, the surface of the reflecting plate 6b slants slightly, so convergence positions of luminous flux emitted from two mirror images 2' are slightly deviated from the center of the photodetection surface to right and left. Therefore, the peak of illuminance on the photodetection surface is slightly low, but spread to right and left. Further, the peak does not spread merely symmetrically, but the part with high illuminance is expanded and the shape of the illuminance distribution approximates to a rectangle, so high illuminance is obtained over a wide area.

Filed: 1979-07-06
Abstract: PURPOSE:To prevent the latch inversion caused by injection of the noiselike electron, by inserting the delay circuit consisting of the resistance and the capacity between the output of the inverter constituting the latch circuit and the input of the other inverter. CONSTITUTION:It is supposed that output terminal 11 of one inverter constituting the latch circuit and input terminal 17 of the other inverter are at a high potential each and that output terminal 12 of the other inverter and input terminal 18 of one inverter are at a low potential each. And now if the noise-like electron is injected to terminal 11, the potential of terminal 11 becomes lower than that of terminal 12. In such cases, the potential of terminal 17 does not lower immediately owing to existence of resistance 15a and parasitic capacity 19a, and MISFET13b maintains the conducting state. At the same time, MISFET13a does not conduct yet, and the potential of terminal 11 ascends again due to resistance 14a and the charge of terminal 18. And if the value is set for resistances 15a and 15b plus parasitic capacities 16a, 16b, 19a, and 19b each so that the potential of terminal 11 may become higher than the potential of terminal 12 before FET13b becomes nonconductive, the potential of terminal 11 is reset to a high potential.

A clear pulse (d) is obtained by adding an output Q and Q' of said both FFs 14, 15 by an AND gate 16, and the pulse (d) is provided to a counter 12. A clock input of this counter 12 becomes a signal (b), the pulse (d) is used as a clear input, and a prescribed counting output is generated and is inputted to a decoder 13. In this way, the operation in case when a ghost, a noise, etc. exist is stabilized by using gates 27, 29 in the decoder 13, and fetching a prescribed counting signal as a gate pulse (e) from an output of the counter 12.

Abstract: PURPOSE:To prevent falling of hot water temperature, by a method wherein, in a water heater, when hot water is intermittently used at intervals of a short time, a prepurging is eliminated and an igniting motion is conducted when there is no remaining unburnt gas in a combustion chamber and no hazard of an explosion ignition. CONSTITUTION:In cae a tap is opened again after hot water is fed once and the tap is closed, an igniting motion varies with the presence of unburnt gas in a combustion chamber by means of an unburnt gas detector 55 and an unburnt gas detecting circuit 56. In case unburnt gas is not detected, a prepurge timer circuit in an IC combustion control circuit 21 is brought to a tied-up state. If a current switch 7 is brought to ON by opening the tap again, a transistor 9 turns ON, and a relay 12 turns ON, whereby valves 41 and 42 are immediately opened to perform a direct firing. In case the presence of unburnt gas is detected in a combustion chamber, an igniting motion is performed after a prepurging motion is conducted.
