Title: Optical information recording and reproducing device
Inventor: MIYAMOTO MORITOSHI
IPC: G11B7/135
Filed: 1990-09-07
Abstract: PURPOSE:To facilitate the manufacture of this device and to contrive the reduction in cost by using an optical element interposing a dielectric multilayer film with two planar glass materials for a means where the optical axes of two luminous fluxes are aligned with each other, transmitting one luminous flux and reflecting the other luminous flux with the dielectric multilayer film. CONSTITUTION:A recording medium 1 is irradiated with two luminous fluxes having different wavelengths emitted from two light sources 21, 22 by using a common optical system, and information is recorded, reproduced, or erased as recording pits on the recording medium 1. Then, for the optical system the optical elements 51, 52 interposing the dielectric multilayer film with the two planar glass materials are used for the means where the optical axes of the two luminous fluxes are aligned with each other so that the recording medium 1 is irradiated with the light in the same optical axis, then one luminous flux is allowed to transmit through the dielectric multilayer films and the other luminous flux is allowed to reflect. Accordingly, dichroic prisms and polarized beam splitters can be composed in plate forms. Thus, as the optical system element, the manufacture is facilitated and the reduction in the cost is attained.

Filed: 1984-11-09
Abstract: PURPOSE:To attain ease of isolation by forming plural scanning signal lines and feedback signal lines in matrix, connecting optical switching elements among both the signal lines and driving the elements by a light emitting means. CONSTITUTION:The optical switching elements D11-DNN are connected between the scanning signal lines S1-SN and the feedback signal lines R1-RN and the elements are driven by the light emitting elements L11-LNN.

Title: Nozzle for metal burner
Inventor: UEMATSU KAZUO
IPC: F24V30/00
Filed: 1983-12-16
Abstract: PURPOSE:To prevent a nozzle from being damaged by fusion even if burning operation is effected for a long period of time by constituting a nozzle tip of a fireproof metallic material. CONSTITUTION:The nozzle tip, faced toward the side of the vessel of fused metal in the nozzle for metal burner in which an oxidizing agent is fed to the fused metal, is constituted of the fireproof metal. A metal, provided with a high melting point and a large high-temperature strength generally such as the pure metal or the alloy of Nb, Ta, W, Mo or the like, for example, is preferable as the fireproof metal. Above all, the pure metal and alloy of Mo are prominent in an anti-corrosion property against fused metal and air, the high-temperature strength and workability and are light in the weight thereof, therefore, they are optimum as the material of the nozzle. In the metal burner 2, the oxidizing agent gas, injected out of the nozzle 1, reacts with the fused metal 3 and produces a flame 5. Accordingly, the flame 5 can not be separated from the nozzle 1 substantially and the tip end of the nozzle 1 is exposed to a high temperature locally. The damage of the nozzle 1 due to the fusion thereof may be minimized and the combustion may be effected for a long period of time by making the tip of the nozzle 1 by the fireproof metal, or, most preferably, by the alloy of molybdenum.

Title: Semiconductor photodetector and image sensor
Inventor: NONAKA KENICHI
IPC: H01L31/10
Filed: 1993-09-22
Abstract: PURPOSE:To obtain a signal corresponding to the intensity of a light entering a super-lattice structure light detecting part which is provided on a semiconductor substrate by a method wherein a field effect transistor is built up on the light detecting part and a gate voltage is applied to the field effect transistor. CONSTITUTION:A field effect transistor 20 is built up on a diode 10 which is an infrared detector. While the infrared radiation does not enter, a superlattice infrared absorbing layer 12 has a relatively high resistance and a substrate bias is not applied to the channel of the field effect transistor 20. Therefore, a current is applied to the field effect transistor 20. On the other hand, when the infrared radiation enters, the superlattice infrared absorbing layer 12 shows low resistance corresponding to the intensity of the infrared radiation and the current applied to the field effect transistor 20 is reduced. Thus, the information concerning the intensity of the incident infrared radiation can be detected by the current applied to the field effect transistor 20.

Filed: 1990-09-05
Abstract: PURPOSE:To realize switching at zero current by indirectly detecting a phase lag between the current flowing to a heating coil and the output voltage of an inverter with one current detector and tuning the switching frequency of a transistor to the resonance frequency of a heating coil. CONSTITUTION:The regenerative current of the power source line of an inverter 21 is detected by one current detector 14. Next, a phase difference is detected by a microcomputer 23 based on the output of a current detector 14 and the output timing of the base signals of transistors 7a, 7b. Then, the base signals are controlled by the microcomputer 23 to make the phase difference zero so that the phase of current is made to coincide with that of voltage by tuning the switching frequency of the transistors 7a, 7b to the resonance frequency of a heating coil 2. It is thereby possible to reduce a switching loss by zero current switching.
