摘要： When plug is fitted to adapter, optical fiber is inserted to an alignment hole for the optical fiber. By providing a taper at the entrance thereof, even if the tip of the optical fiber is deviated from the central position, the deviation is absorbed to make it possible for the optical fiber to be inserted smoothly. When two plugs is fitted to adapter, the tip of one optical fiber is confronted with the other one in the alignment hole, and excessive length L.sub.1 -L.sub.2 is pushed into the two optical fiber-bending spaces with a suitable distribution, thus the optical fiber buckles therein. The end face of the optical fiber is subjected to flat surface-polishing, removal of ripples after being cleaved, or chamfer grinding after being cleaved. The buckling portion of the optical fiber is coated with carbon or the like.

摘要： 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.

摘要： 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.

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.
