    摘要: An elevator control system includes a power source which supplies AC power to an induction motor for driving an elevator car through a first thyristor gate circuit. Another induction motor provided for braking the elevator car is connected to the power source through a second thyristor gate circuit. A tachometer generator connected to the induction motors produces an speed signal indicative of the speed of the elevator car. The speed signal is compared with a reference signal and the difference therebetween is used to control the first and second thyristor gate circuits for controlling the elevator car speed.

    摘要: A nonvolatile optical memory element in which a ferromagnetic body is provided on a semiconductor causes such a problem that in a case where magnetization of the ferromagnetic body is read by light, magneto-optical response becomes very small when the ferromagnetic body is small in volume. The present invention provides a memory element, a memory device, and a data reading method, each of which is applicable to data reading from a nonvolatile optical memory element. In a nonvolatile optical memory element having a structure in which a ferromagnetic body is provided on a semiconductor that is connected to an optical waveguide, electrons are injected into the semiconductor via the ferromagnetic body so that the electrons that are spin-polarized according to a magnetization direction of the ferromagnetic body are injected into the semiconductor, thereby enlarging a region in which a photomagnetic effect occurs effectively. By applying an electric pulse and an optical pulse to the nonvolatile optical memory element, it is possible to effectively read recorded data according to a magnetization direction of the ferromagnetic body.

    摘要: A first tag communication apparatus is adapted to perform radio communications with a second tag communication apparatus and an RFID tag provided on a moving object. A controller is operable to cause an antenna to transmit first radio waves while changing a first direction that the first radio waves are transmitted. A receiver is operable to receive a second radio waves transmitted from the second tag communication apparatus. An extractor is operable to extract, from the second radio waves, synchronizing information indicative of a timing that the second tag communication apparatus changes a second direction that the second radio waves are transmitted therefrom. A synchronizer is operable to synchronize a timing that the controller changes the first direction with the timing that the second tag communication apparatus changes the second direction, based on the synchronizing information.

    摘要: When a spark discharge is produced, a first current flows in one direction. From a rise of an ignition signal to energize an ignition coil to a fall of the ignition signal to deenergize the ignition coil, in order that a second current flowing in the opposite direction can be detected, the voltage into which the second current has been converted is compared with a first threshold voltage for smolder detection. After the fall of the ignition signal to the rise of the ignition signal, the voltage into which the second current has been converted is compared with a second threshold voltage for misfire detection. The first threshold is set larger than the second threshold.

    摘要: A bearing retainer unit is formed by an insert-molding technique to cast a molded component of the bearing retainer unit utilizing a bearing bushing. A first mold die, having a circumferential surface shaped to correspond to at least a portion of the inner circumferential surface of a bearing-positioning portion of the molded component, and a second mold die, having an abutment that abuts against an axial end face of the first die, are readied. A molten material is then injected into the mold to form the molded part, thereby forming the die-parting line on the inner circumferential surface of the component's bearing positioning portion, positioned at the radially outer side of the abutment.

    摘要: An ion current detecting device includes an ion current detecting unit which detects ion current based on combustion ion generated after an ignition which is performed in a combustion chamber and an amplifier unit which amplifies ion current detected by the ion current detecting unit. The amplifier unit has an amplification rate which is set so that an output amplified ion current varies nonlinearly with ion current of the ion current detecting unit. Thus, the amplifier unit enables the amplification rate to vary according to a level of ion current. Therefore, ion current can be detected correctly even if a minute ion current is generated when the spark plug malfunctions etc., and even if ion current becomes higher.
