摘要： A slide member is slidable along a slide rail provided at a vehicle-body side portion. When lock pawls provided at the slide member are engaged with the slide rail, the slide member is locked. The slide member is unlocked by operating an operation cable connected to the lock pawls. The operation cable is fitted to a fitting portion of an attachment bracket connected to the slide rail. A portion from a fixed portion fixed to the fitting portion to a movable portion (one end portion) extends through a region where a non-contact portion is disposed, and does not contact the non-contact portion. The movable portion is connected to the slide member and moved integrally with the slide member.

摘要： A silicon-based thin film depositing apparatus, including a plurality of transparent electrodes disposed to face corresponding counter electrodes with a space therebetween. Subsequently, while injecting a raw material gas from raw material gas injection orifices toward the supporting electrodes and also injecting a barrier gas from barrier gas injection orifices in the same direction as the direction in which the raw material gas is injected, the gases are discharged from a gas outlet, and thereby, the pressure in a chamber is controlled to a pressure of more than 1 kPa. Then, a DC pulse voltage is applied to each counter electrode to deposit a silicon-based thin film. A DC pulse voltage is applied to perform discharge. Therefore, even in a state where the distance between the electrodes is increased, plasma can be generated efficiently, and the in-plane distribution of film thickness can be improved.

摘要： A pulsed power supply includes a DC power source, and a transformer and a switch which are connected in series with each other across the DC power source. The pulsed power supply operates to produce a plurality of high-voltage pulses in a repetition of cycles in each of which an induced energy is stored in the transformer when the switch is turned on and a high-voltage pulse is generated across a secondary winding of the transformer when the switch is turned off. The current flowing through the primary winding of the transformer is controlled to keep its peak value constant. The pulsed power supply further includes a current detector for detecting the current flowing through the primary winding of the transformer, and a third circuit for turning off the switch when the current detected by the current detector reaches the peak value.

摘要： Metallic particle layers with metallic domains being arranged therein each at a predetermined space within a horizontal plane are laminated at an appropriate distance in the vertical direction in a dielectric layer. The distance ΔW between each of the metallic domains may be controlled by controlling the growth of metallic particles for the horizontal direction and the distance ΔL between the metallic particle layers may be controlled by controlling the thickness of the dielectric layer to be laminated for the vertical direction, so that the effect of field enhancement by plasmon resonance is improved by satisfactory control for the plasmon resonance in the direction of the thickness and in the direction orthogonal thereto.
