Title: Manufacture of compound semiconductor device
Inventor: HAGIO MASAHIRO
IPC: H01L21/306
Filed: 1980-06-16
Abstract: PURPOSE:To prevent the deterioration of the initial characteristics of, for example, a GaAs Schottky gate FET by etching a metallic layer formed on a thin active layer to form an electrode structure, then cleaning it with water soluble organic solvent. CONSTITUTION:In a step of forming the electrode of, for example, GaAsFET, a Schottky gate electrode 3 is etched and formed, and water soluble organic solvent, e.g., methyl alcohol, ethyl alcohol, acetone, etc. is used in the step of cleaning and removing the etchant. Since these organic solvents do not oxidize the GaAs, a oxidized region 4 is not formed in the active layer 2 in the periphery of the electrode 3. Even if the thickness t of the layer 2 is formed less than 0.5mum in the element, the cleaning step can be carried out without deteriorating the characteristics, e.g. power gain, noise index, etc.

Title: Inductive heating device
Inventor: OGURI HISAAKI
IPC: H05B6/10
Filed: 1992-04-03
Abstract: PURPOSE:To improve heating efficiency and shorten a heating time by keeping the thickness of the conductive magnetic plate of an inductive heating device at 1.3 to 2.4 times the thickness of the skin effect of the plate. CONSTITUTION:Alternating current flows through a coil 1 and alternating field occurs in the vicinity of the coil 1. As a result, magnetic field appears along a magnetic path formed with a core 2 laid below the coil 1 and a magnetic plate 4 as a heating object. Also, eddy current flows inside the magnetic plate 4, due to an induced electromotive force generated with the time change of magnetic flux in the plate 4. An eddy current loss is thus generated. This loss acts to heat the plate 4. The thickness delta of the skin effect of the plate 4, when calculated according a specific formula, is 2.7mum and heating efficiency becomes maximum, when the thickness of the plate 4 is taken at 1.4 to 2.4 times the depth delta of the skin effect, or within the range of 32 to 54mum, thereby giving high efficiency equal to or less than 95% of the highest efficiency at 40mu thickness (about 1.8 times). As a result, a time required from the start of heating to the attainment of a necessary calorific value can be further shortened.

Filed: 1979-06-29
Abstract: PURPOSE:To improve durability of a small amount of adsorbent, by employing an arrangement in which removal of phosphorous components contained in metalling oil by way of adsorption is not effected in a temperature range of catalyst where phosphor contamination of catalyst does not tend to take place. CONSTITUTION:A directional control valve 15 is disposed at a joining portion of metalling-oil supply pipe 11 and by-pass pipe 14 for by-passing metalling oil from adsorbent 13. When the temperature of catalyst 6 is higher than a predetermined temperature (700 deg.C), the directional control valve 15 functions to pass metalling oil to adsorbent 13 by means of temperature detector 17 for detecting the temperature of catalyst 6 by temperature sensor 16. On the other hand, when temperature of catalyst 6 is lower than the predetermined temperature, valve 15 functions to pass metalling oil to by-pass pipe 14. That is, phosphorous components in metalling oil is adsorbed by adsorbent 13 only when phosphor contamination of catalyst 6 tends to occur. Therefore, durability of adsorbent 13 can be improved considerably.

Abstract: PURPOSE:To perform the high-quality communication of information by means of the space propagation of an optical signal, by making the emission wavelength of the optical signal, which is outputted from the light source of a transmitter, to be a specific length. CONSTITUTION:A light transmitter-receiver 2 having a semiconductor laser element as its light source radiates an optical signal outputted from the laser element in the directional angle of, for instance, + or -60 deg. from the ceiling of a room 1 toward each light transmitter-receiver 5 of a terminal 4 arranged on a floor surface. For each light receiving part of the transmitter receiver 5, information communication is performed by the propagation of an optical signal having the wave length of 1.38-1.43mum. In this case, since the level of sunlight component with respect to the optical signal of the wavelength of 1.38-1.43mum is about 1/10, the background noise of the sunlight does not bother the optical signal.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a temperature measuring method and device for a tie plate in the length direction which eliminates any effect of disturbance such as cooling water stuck to the surface of the tie plate. SOLUTION: When a radiation thermometer 11 simultaneously receives width- directional radiation lights of a tie plate (a), it is photoelectrically transferred so as to output multipoint temperature signals S1 in the width direction. A temperature converter 12 obtains temperature distribution pattern signals S2 based on the temperature signals S1 and outputs the temperature distribution pattern signals S2 and synchronous signals S3. A peak temperature detector 13 holds the maximum voltage value (maximum temperature) among the temperature distribution pattern signals S2 and outputs it to a temperature deviation detector 14. The temperature deviation detector 14 compares the peak temperature signals S4 inputted every moment with the target value to find the deviation and the found deviation is outputted as the deviation signals S5.
