摘要： An optical disc cartridge for storing an optical disc. The cover of the optical disc cartridge absorbs or filters ambient light which may damage information stored on the disc after prolonged exposure to the ambient light. Preferably, the disc cartridge cover allows some visible light to pass in order to allow a user to read label information on the disc. The color of the cover may be transparent to visible light, allow only specific visible wavelengths of light to pass, or be opaque, as long as the amount of ambient light reaching the disc stored within the disc cartridge is reduced. The disc cover may be made of a single layer or include a base layer with one or more thin films thereon.

摘要： Semiconductor layers are formed on a substrate, and an insulating film is formed on the semiconductor layers. On the insulating film is formed a gate electrode, which has emitter holes formed therein. In the emitter holes are formed emitters, which are provided with emitter electrodes via the semiconductor layers. The emitters are grouped into a plurality of emitter groups each having at least one emitter. The emitters of each of the emitter groups are connected to each of the semiconductor layers. Common electrodes are formed across the semiconductor layers via the insulating film. Thereby, a field emission type cold cathode element is obtained which has nonlinear characteristics of providing a low resistance in normal operation and a high resistance upon discharges.

摘要： A dust proof recording and reproducing apparatus has a movable tray for ejecting or loading a recording medium. The tray has a tray port through which it moves. A force element, such as a spring, forces an outer cover for the port towards an inner cover. The force element absorbs variations in the stopping position of the tray in a loaded condition so that the outer cover always contacts with and closes the outer circumferential area of the tray port.

摘要： A field emission cold cathode device is driven to make an emission current constant without limiting the available choice of materials for a gate electrode. A positive voltage with reference to OV is applied from a gate power supply to gate electrode of the field emission cold cathode device to enable emitter disposed respectively near the gate electrode to emit electrons. After the positive voltage with reference to OV is applied, a negative voltage with reference to OV is applied from the gate power supply to the gate electrode at a predetermined time.

摘要： The present invention provides a disk drive unit which includes a body case having an opening portion for inserting a disk cartridge and for facilitating removal of the cartridge from the body case. A shutter mechanism having a shutter which is rotatably supported in the body case and is movable between an open position for inserting the cartridge and a closed position for preventing airborne debris from entering the interior of the body case. The shutter is normally in the closed position and is opened when a cartridge is inserted or ejected. A loading device is positioned within the body case and is configured to vertically move the cartridge so as to load the inserted cartridge onto a driving device. The loading device also selectively ejects the cartridge in an ejection movement. A driving device is provided to rotate a disk stored in the cartridge and is preferably fixed to the body case. The shutter mechanism also includes a cam linked with the shutter which is provided to rotate or pivot the shutter upwardly in association with the ejection movement of the cartridge caused by the loading device so as cause the shutter to move to the open position when the cartridge is being ejected.

摘要： An optical disk drive unit has an opening portion formed in a body case to insert an optical disk cartridge having an optical disk therein into the body case and take the optical disk cartridge out of the body case; a driving device for receiving and rotating the optical disk; and a rotatable shutter for opening and closing the opening portion. A leg portion extends from a shutter body. A center of rotation of the leg portion is located on a side of the driving device disposed within the body case and away from the opening portion of the body case. No closing operation of the shutter body is influenced by mounting the optical disk cartridge into the body case. At least one face of the shutter may be constructed by an arc face having a shape approximately equal to the shape of an arc around the center of rotation. A projecting portion may be disposed outside the shutter. In this case, a lower portion of the projecting portion comes in contact with the optical disk cartridge after an end portion of the projecting portion comes in contact with the optical disk cartridge.

摘要： A method of selective epitaxial growth includes a step of selectively forming an insulator film on a predetermined region of a semiconductor substrate and a step of evaporating a starting material containing a Group III element in vacuum in the presence of a Group V element to grow epitaxially a III-V compound semiconductor selectively on the semiconductor substrate under the condition where the partial pressure of the Group III element just above the semiconductor substrate is greater than the equilibrium vapor pressure of the Group III element contained in the III-V compound semiconductor existing on the semiconductor substrate and is smaller than the equilibrium vapor pressure of the Group III element contained in the III-V compound semiconductor existing on the insulator film.When InAs is grown epitaxially and selectively on a GaAs substrate, the GaAs substrate is kept at 500.degree. to 650.degree. C. and when GaAs is grown epitaxially and selectively on the GaAs substrate, the GaAs substrate is kept at 700.degree. to 775.degree. C.
