Abstract:
A photosensor circuit comprises a photoelectric transducer, an n-channel MOS transistor and an initial setting unit for precluding the occurrence of a residual image phenomenon. When an optical signal is generated by the photoelectric transducer, the initial setting unit sets the gate voltage of the n-channel MOS transistor at a high value for a predetermined time to lower the drain-source impedance of the n-channel MOS transistor to thereby control charge or discharge of a capacitor connected to a source terminal.
Abstract:
An X-ray examination apparatus includes an X-ray diagnosis apparatus (first imaging area), an X-ray CT apparatus (second imaging area), a bed, and the X-ray diagnosis apparatus and the X-ray CT apparatus are arranged along a path of movement of a top plate of the bed in such a manner that the first and second imaging areas are spaced a predetermined distance from each other in a path of movement of the top plate. There is provided a top plate reciprocal movement control means which through operations of switches moves the top plate forward and backward between a first top plate position where a desired part of the patient is positioned at the first imaging area and a second top plate position where the top plate is spaced from the first top plate position toward the X-ray CT apparatus by a distance corresponding to the distance between the first and second imaging areas so that in the reciprocal movement of the two apparatuses, the top plate can be stopped at the first and second top plate position.
Abstract:
The suitability of diagnosing deterioration of a catalyst which purifies engine exhaust is determined based on estimated catalyst temperature. A value depending on condensation in the catalyst, and a value corresponding to a state without condensation, are respectively set as a reference heat amount for a cold start and a hot start. A catalyst temperature during steady state running condition of the engine is also computed based on the engine running conditions. The heat amount given by the exhaust to the catalyst is computed from this catalyst temperature and the engine intake air volume. When the total heat amount given to the catalyst after engine startup is equal to or less than the reference heat amount, a catalyst temperature estimated value is set to a fixed value. In all other cases, the catalyst temperature estimated value is calculated by a first order delay equation having catalyst temperature during steady running conditions as a parameter. In this way, the catalyst temperature is estimated with high precision.

Abstract:
A coin throwing port restricting mechanism 10 enables substantial restriction of a configuration of a coin throwing port 4 by means of a simply handling thereof. Such a coin throwing port restricting mechanism 10 contributes to provide a coin throwing device which has only one coin throwing port 4 and which can receive many kinds of coins of different sizes. The coin throwing port restricting mechanism 10 comprises a ring 11 and an arm 12. The ring 11 which serves as a fixing member surrounds the coin throwing port 4. The arm 12 extends from the inner periphery of the ring 11 to the center thereof in a manner that it faces front to the coin throwing port 4. The extending length and the extending width of the arm 12 are selectable depending on the diameter and the thickness of the coin. Thus, the configuration of the coin throwing port 4 can be restricted without modifying the shape thereof.
