摘要:
A gas turbine control system is disclosed which operates to stabilize the system frequency in a case of transitional variations of the system frequency without making the strength of hot gas path parts of the gas turbine below a maximum stress value of the hot gas path parts. When a system frequency abnormality is detected, the output of the gas turbine is adjusted to recover the system frequency by making a gas turbine combustion gas temperature control inoperative. For this purpose, there are provided a logical circuit operative to make the gas turbine combustion gas temperature control disabled or inoperative in response to an abnormal system frequency detection signal, and a recovery circuit that operates to cancel the inoperative state of the gas turbine combustion gas temperature control. The detection of an abnormal system frequency may be carried out by an outside signal. An abnormality detection unit may be provided in a combined cycle plant.

There is provided a mold clamping apparatus that can prevent a molding material from spouting from a split surface of a mold even if in-cavity resin pressure causes offset of a mold opening force, and can extend the life of the mold. The mold clamping apparatus includes a control device that estimates a mold opening force by mold internal pressure for molding with mold internal pressure being asymmetrical with respect to a center of a mold block, determines a mold clamping hydraulic value applied to each tie bar correspondingly to the estimated mold opening force, and distributes hydraulic pressure supplied to each tie bar so that the determined mold clamping hydraulic value is reached.

An imaging system is provided that is capable of controlling a photographic operation to provide favorable images of a fundus of an eye to be examined. When a normal photographic mode is selected, a single operation of a shutter button causes a single trigger signal to be generated. On the other hand, when a stereo photographic mode is selected, a single operation of a shutter button causes two trigger signals to be generated in succession. The generated trigger signal triggers a switching device so that a position of a photographic stop is automatically switched to a position predetermined for the photographic mode, and the photographic light source is caused to emit light a number of times that corresponds to the selected photographic mode. In such a configuration, fundus images are automatically produced a set number of times by a single operation of the shutter. Therefore, a high-quality fundus image can be obtained without concerns that an appropriate moment to capture an image will be missed.

A vehicle start-up permission device in which an identification code stored in an electronic key can be kept secret. A start-up permission ECU (1) is magnetically coupled with a transmit-receive controlling circuit (6) of an electronic key (3) via an antenna (2) and an antenna (5) of the electronic key (3) with the electronic key (3) being inserted in an ignition key (4) so as to supply electric power for the circuit. When the ignition switch (4) is operated to an ACC position, the start-up permission ECU (1) transmits a random number code. When the transmit-receive controlling circuit (6) of the electronic key (3) receives the random number code, it converts by predetermined encryption processing a previously registered key code to a return code on the basis of the random number code and returns the return code. When the start-up permission ECU (1) receives the return code, it decodes a key code on the basis of the random number code, and when the key code coincides with the previously registered key code, the start-up permission ECU (1) outputs a start-up permission signal to an engine-controlling ECU (7).

When an ignition switch detects that a key rotor of an ignition key cylinder has been turned to the accessory position by a key, a controller energizes a primary coil to cause it to output a high-frequency signal. In the key, a secondary battery is charged with a constant DC voltage generated from an AC voltage induced across a secondary coil. A transmission circuit is powered by the secondary battery, and allowed by a timer circuit to transmit a radio signal including an identification code during a predetermined period after the high-frequency signal is received by the key. Alternatively, the controller energizes the primary coil plural times with a cycle consisting of predetermined output and pause periods if the transmitted identification code does not coincide with a preset identification code at the first comparing attempt.

In a vehicular communication system, a microcomputer of a transmission-reception electronic control unit (ECU) transmits stored data via an antenna coil to a transceiver disposed in an ignition key when the ignition key is inserted in an ignition key cylinder of a vehicle. During communication with the transceiver, the microcomputer outputs a key interlock actuating signal. While the key interlock actuating signal is being inputted to a key interlock control circuit, the key interlock control circuit operates a key interlock actuator to prevent the ignition key cylinder from being turned to a position at which the ignition key may be freely removed from the ignition key cylinder. Thus, the ignition key is prevented from being removed from the ignition key cylinder during communication between the ignition key transceiver and the microcomputer, thereby ensuring that data about the vehicle will be stored in a reception device disposed in the ignition key without a failure.

A stepped insulating ring having a large-diameter upper portion, a small-diameter foot portion, and a step portion formed on the inside is inserted from a top opening of a bottomed cylindrical can containing a plate group and electrolyte and the small-diameter foot portion is set onto the plate group, a peripheral portion of a cover in which a safety valve is incorporated is set onto the step portion of the stepped insulating ring, and the areas to be sealed where an inside wall of top opening of the bottomed cylindrical can faces an outside wall of the large-diameter upper portion of the stepped insulating ring and an inside wall of the large-diameter upper portion faces a peripheral portion of the cover is formed, and when crimping operation on said areas to be sealed is performed from the outside of the upper part of the bottomed cylindrical can to form a closed construction, a sealing compound consisting of oily bitumen, organic solvent, and paraffin base oil is applied to the areas where an inside wall of top opening of the bottomed cylindrical can faces an outside wall of the large-diameter upper portion of the stepped insulating ring and an inside wall of the large-diameter upper portion faces a peripheral portion of the cover before the areas to be sealed are formed, and drying operation of the sealing compound is performed. On the battery obtained, the leakage of electrolyte scarcely occurs even in a high-temperature, high-humidity environment.
