Abstract: A storage case includes a frame, a top plate, and a drawer. The top plate covers an open upper side of the frame. The drawer is movable through an open front side of the frame. A bottom plate of the frame includes grooved rails and guide walls. The grooved rails are formed at left and right sides of the bottom plate. The guide walls are formed at left and right sides of the inner surface of the bottom plate so that the left and right side plates of the drawer are slidable along the guide walls. The drawer includes guide projections formed at rear left and right sides of the bottom plate. The guide projections are fitted to the grooved rails so that the guide projections are movable along the grooved rails.

Abstract: An optical device manufacturing apparatus includes an encapsulating device for encapsulating an optical semiconductor element 4 mounted on a substrate 2 by a liquid resin R in a lens shape, and a curing device for curing the liquid resin R, wherein the encapsulating device includes a dispenser capable of vertically moving a nozzle 25 for supplying the liquid resin R, and brings the tip of the nozzle 25 close to the optical semiconductor element 4 and then supplies the liquid resin R while raising the nozzle 25. According to this optical device manufacturing apparatus, an optical device having the desired optical properties can be obtained promptly and easily.

Abstract: A disk drive device equipped with a disk transfer mechanism for loading a disk into and out of a play position that does not increase the complexity of the overall structure and the size of the housing. The device comprises a tray for supporting a disk within the housing, first and second transfer rollers carried by arms, that are resiliently urged against the peripheral edge of the disk, and spaced from each other along a side of the tray to apply a rotational force to a side peripheral edge of the disk, and fixed guide members for supporting the other side peripheral edge of the disk that is inserted from the slot.

Abstract: A level marking apparatus capable of directly measuring height comprises an elastic synthetic resin tube. One end of the tube is secured to a pressure sensor capable of producing an output voltage and air-tightly sealed, and the other end of the tube is connected to a reference instrument, which has a larger diameter and is shorter in length than the tube. The tube is totally filled with low viscosity macromolecule liquid. Moreover, the pressure sensor is connected to a micro computer programmed to find an average value of fluctuation waveform within a certain cycle of output voltage of the pressure sensor. The micro computer also calculates and memorizes a reference level based on a pressure difference between the reference instrument and the pressure sensor when placed at different heights. Additionally, a marking device is connected to the pressure sensor, and it is actuated by an ON signal from the pressure sensor.
