To provide a disk supporting apparatus, a disk holding apparatus and a disk apparatus whose planar dimension is minimized, and which can be manufactured simply and inexpensively.A plurality of supporting portions 44 inclines with respect to a top portion 46 as a vertex. A tray 26 is formed into a substantially triangular pyramid (three-dimensional) configuration, and a planar dimension of the tray 26 can be smaller than that of a conventional turntable. Accordingly, a plurality of disks can be mounted on the tray 26. The supporting portion 44 of the tray 26 can be placed in parallel to a door leaf without a slide mechanism that has conventionally been used for sliding a tray. Accordingly, a desired disk can be attached/detached merely by rotating and driving the tray 26, and a mechanism disposed at a stereo apparatus is made compact and manufactured inexpensively.

A semiconductor laminating portion including a light emitting layer forming portion having at least an n-type layer and a p-type layer is formed on a semiconductor substrate. A current blocking layer is partially formed on its surface. A current diffusing electrode is formed on the entire surface thereof. A bonding electrode is formed thereon. The semiconductor laminating portion and the current diffusing electrode are separated into light emitting unit portions A, electrode pad portion B, and connecting portions C for connecting between electrode pad portion B and light emitting unit portions A or between two of the light emitting unit portions A, and the semiconductor laminating portion between the light emitting unit portions A is removed through etching to make clearances except for connecting portions C. The bonding electrode is formed on electrode pad portion B.

A semiconductor light emitting device is formed by adhering a semiconductor layered portion having a light emitting layer forming portion to a conductive substrate via a metal layer. The metal layer has at least a first metal layer for ohmic contact with the semiconductor layered portion, a second metal layer made of Ag, and a third metal layer made of a metal which allows adhesion to the conductive substrate at a low temperature. As a result, the rate of reflection of light from the metal layer increases due to the presence of Ag in the metal layer. Further, the metal in the metal layer is prohibited from diffusing into the semiconductor layer, so that the semiconductor layer does not absorb light. And therefore the brightness of the semiconductor light emitting device can further be increased.

A fuel injection control system for an internal combustion engine comprises a plurality of fuel injector valves, a pumping system having a suction valve, a discharge valve, and a high-pressure pump section sucking fuel into a pressurized chamber with the suction valve opened on a suction stroke and for discharging the fuel in the pressurized chamber toward the injector valves with the discharge valve opened on a discharge stroke. A relief passage is connected, at one end, to a lowpressure line upstream of the suction valve. The other end of the relief passage is connected to the pressurized chamber. A fuel-pressure control valve is disposed in the relief passage for regulating a fuel pressure of the fuel injected from each of the fuel injector valves by opening the fuel-pressure control valve only for a specified time duration from a controllable middle stage of the discharge stroke to the end of the discharge stroke.

A bidirectional signal distributing system which can use a sweet sleep system at home without exerting a burden on a subscriber so as to purchase the sweet sleep system. Luminance change frequency data and/or audio change frequency data suitable to shift to a sweet sleep state of the subscriber has been stored in a head end apparatus in the bidirectional signal distributing system. When the subscriber requests a sweet sleep function, the luminance change frequency data and/or audio change frequency data according to the subscriber provided on the head end side is read out, a predetermined video signal and/or audio signal is modulated, and the modulated signal is transmitted to the subscriber apparatus.
摘要:
A magnetic recording medium which comprises a non-magnetic substrate, a magnetic recording layer formed on one side of said substrate, and a back coat layer formed on the other side of the substrate. The back coat layer is made of a composition which comprises particles of carbon black, titanium monoxide or a mixture thereof having an average size not larger than 1 micrometer and a resin binder dispersing the particles therein. The particles are individually precoated with an isocyanate compound. When coated titanium monoxide particles are used singly, non-coated carbon black is effectively used in combination.

A magnetic recording medium of the type comprising a non-magnetic substrate and a magnetic recording layer formed on at least one side of the substrate. The magnetic recording layer comprises particulate alpha-Fe.sub.2 O.sub.3 and carbon black as additives dispersed in a resin binder along with a magnetic powder. These additives serve to improve magnetic characteristics and a ilght-shielding property. When vinyl chloride-vinyl alcohol copolymers are used as the binder, further improvements are achieved.

Magnetic recording media which comprise a support, a magnetic recording layer on one side of the support, and a non-magnetic layer comprising TiO on the other side are described. The non-magnetic layer is made of a dispersion of TiO particles in a resin binder or is a continuous vacuum-deposited TiO layer.
摘要:
The output of a first bridge circuit including as one component element a thermistor for detecting the temperature of a pan is compared with a preset value in a first operational amplifier. The first operational amplifier provides a low level output when the detected temperature is below a predetermined temperature. When this low level output is supplied to a second operational amplifier, the output thereof goes to a high level to turn on a transistor so as to energize a relay for passing current to a cooking heater. When a cooking end temperature is reached, the internal resistance of the thermistor is reduced, and as a result the output of the first operational amplifier goes to a high level, causing the output of the second operational amplifier to go to a low level. Thus, a warming heater is energized while the cooking heater is de-energized.
