摘要:
A solid-state imaging device includes a substrate, and an array of charge-packet storage cells or picture elements (or "pixels") arranged on the substrate, each including a storage diode that stores therein a signal charge packet indicative of an incident light. A charge transfer section is coupled with the array of picture elements. The transfer section includes a charge-coupled device (CCD) register layer that is spaced apart from the storage diode to define a channel region therebetween, and a first insulated electrode overlying the register layer and the channel region. A reset section is coupled to the storage diode, for potentially resetting the storage diode by additionally injecting an extra charge packet into the storage diode and by causing the charge to drained from the storage diode. A potential controller is provided which forces, when a signal charge packet is read out of the storage diode toward the CCD register layer, the storage diode to decrease in potential so that the storage diode becomes potentially less than its potential as set during the reset operation, while causing the channel region to be fixed at almost the same potential during the read operation and the reset operation.

A throttle passage is formed by providing a step portion by expanding an open end side of a refrigerant passage of the refrigeration cycle, placing a throttle passage member on the step portion, and squashing the throttle passage member using a columnar squashing jig to widen a rim of the outer periphery, thereby causing the throttle passage member to be fixedly engaged to an inner wall of the refrigerant passage. The throttle passage member has a simple shape formed only by machining a circular plate having a hole formed in a center thereof into a truncated conical shape, and therefore can be made at low cost. Throttle passage member is only squashed to be fixedly engaged in the refrigerant passage, and therefore can be easily formed.
