摘要:
A semiconductor integrated circuit device includes an address buffer which receives an address signal that indicates an address of a memory cell array, a latch circuit which latches the data, and an address transition detection circuit which detects transition of the address. During the access operation of the memory cell array, an address at the operation start time is latched by the latch circuit. After the end of the operation of the memory cell array, an address that is currently input to the address buffer is latched by the latch circuit. If the received address signal is data different from the latch data, a control signal that controls the cycle operation of the memory cell array for a predetermined period is generated on the basis of the detection result from the address transition detection circuit.

A semiconductor device includes an internal power supply, at least one semiconductor circuit block, a delay circuit, and a detecting circuit. The internal power supply outputs an initialization completion signal when initialized. The semiconductor circuit block operates on the basis of a voltage generated by the internal power supply. The delay circuit delays the initialization completion signal. The detecting circuit commands the semiconductor circuit block to start operations in response to the initialization completion signal delayed by the delay circuit and an externally input first input signal.

A semiconductor integrated circuit device includes a memory, /CE transition detector, address transition detector, /WE transition detector and controller. The controller includes a timeout circuit. The timeout circuit generates an internal circuit control signal with preset width to control access to the memory based on detection results of the above transition detectors. The operation of the memory is controlled by the timeout circuit at the read time. The operation of the memory is controlled by the timeout circuit when transition of the end of a /WE signal is detected by the /WE transition detector before a timing specified by the timeout circuit at the write time. Further, the operation of the memory is controlled in response to the transition of the /WE signal when the transition of the end of the /WE signal is detected by the /WE transition detector after passage of the above timing.

A steering lock device has a steering catch mechanism including a handlebar attached to a steering stem, and a locking arm attached to this handlebar and being equipped with a lock pin for engagement on the tip end portion thereof. The steering catch mechanism also includes a locking claw as an engaging portion that is engagable with the lock pin. The locking claw is usually biased in the unlocking direction. In this catch mechanism, the locking claw is disposed on a rotation track of the lock pin. Accordingly, when an external force is applied to the lock pin such that the lock pin is in contact with the locking claw of the catch mechanism, the locking claw is moved in the locking direction so that the locking claw can be engaged with the lock pin. Therefore, a steering-lock stand-by state is accomplished.

A locking device for a storage box in a vehicle includes a lock configured to place the storage box in a closed state or an open state, and an actuator configured to drive the lock. The locking device further includes a button configured to place the storage box in the open state. The locking device is configured to perform an authentication of a portable key when the button is operated and the storage box is closed. When the portable key is authenticated when the button is operated, the lock is configured to place the storage box in the open state. When the portable key is not authenticated when the button is operated, the storage box is configured to be held in the closed state without the lock being driven. When the portable key is authenticated when the storage box is closed, the lock is configured to be driven to place the storage box in the closed state. When the portable key is not authenticated when the storage box is closed, the storage box is configured to be held in the open state without the lock being driven.

In conventional optical isolators, an optical signal is dispersed by polarization or the characteristics are varied by heat generation in a garnet crystal. According to the invention, the crystal optical axis (3c) of rutile crystal (3) is oriented so that the separation directions of the ordinary ray (O) and the extraordinary ray (E) are perpendicular to the plane including the optical axes of optical fibers (10, 11). Furthermore, the focusing central optical axis (6c) of a focusing rod lens (6) is arranged parallel with optical axes of the optical fibers (10, 11) and at a substantially equal distance from the four rays, i.e. the ordinary ray (O) and the extraordinary ray (E) propagating along the optical axis of the optical fiber (10) and the ordinary ray (O) and the extraordinary ray (E) propagating along the optical axis of the optical fiber (11). An air gap (7) of about 200 [μm] is provided, as a heat insulating means, between the focusing rod lens (6) and a magnetized garnet crystal (8).
摘要:
An object is to provide a high-frequency plasma generating apparatus and process which can further advance uniformity of the thickness of a film on a substrate with a large area in comparison with conventional apparatuses. In a reaction chamber (1), a ground electrode (3) is disposed, and a discharge electrode (2) is disposed opposite to the ground electrode (3). A substrate (4) as a processing object is placed in close contact with the ground electrode (3). A high-frequency voltage is applied to the discharge electrode (2) so as to generate plasma between the ground electrode and the discharge electrode. An RF electric power supply (15) generates a first high-frequency voltage, and outputs the generated voltage on feeding points (9) disposed on a lateral portion of the discharge electrode (2). An RF electric power supply (16) generates a second high-frequency voltage, and outputs the generated voltage on feeding points (9) disposed on another lateral portion of the discharge electrode (2). Here, the second high-frequency voltage has the same frequency as that of the first high-frequency voltage and has a phase which varies with a low-frequency signal, which is modulated by a predetermined modulation signal.
