Patent JP-S61295674-A (JP)
Title: Photoconductive detection element
Inventor: KASAHARA KENICHI
IPC: G02B6/12
Filed: 1985-06-24
Abstract: PURPOSE:To improve a wave tail, to make high the speed of operation and further to furnish PC of high sensitivity, by forming a light-receiving semiconductor layer on a half-insulative semiconductor substrate and by forming the light- receiving semiconductor layer of a P-type semiconductor layer. CONSTITUTION:When electrodes 13 and 14 made up of Ti/Pt/Au are space at 10mum from each other, a time required for electrons generated by irradiation of light to go across the space is 40pS. This value is smaller by one figure than the one in the case of an N-type, and thus a fall time is shortened. On the other hand, thermal noise <it<2>> of PC is expressed by <it<2>>=4kTB/RD, where (k) denotes a Boltzmann constant, T an absolute temperature, B a band and RD the resistance of PC. The electrodes of PC are comb-shaped to increase the efficiency of light reception. While the thermal noise of an avalanche photodiode can be expressed in the same way, a resistance of 50OMEGA or above is connected as RD generally so as to secure matching with an external circuit when APD is used. Accordingly, while the thermal noise in a light-receiving semiconductor layer of an N-type is larger than that in APD, this can be avoided by forming the layer of a P-type one.

Title: Production of spherical ceramic particle
Inventor: MATSUO MASATAKA
IPC: C04B35/00
Filed: 1987-05-30
Abstract: PURPOSE:To obtain fine spherical ceramic particles excellent in sinterability, volume stability and packing properties by spraying and injecting ceramic raw material being a state mixed with combustible liquid into high-temp. flame and making ceramic to a fused or semifused state. CONSTITUTION:Combustible liquid 3 is sent 5 under pressure through a force feed pipe P from a liquid storage tank 1 and the particles 2 of a raw material for ceramic wherein the particle size is previously regulated are fed into this pipe P. The particles 2 of the raw material are sent under pressure to a burner part 6 as a mixture 4 made to a state mixed with the liquid 3, sprayed and injected through the burner 6. Flame 7 is formed from a flame nozzle hole 70 of the burner 6 by feeding combustible gas PG and combustion improving gas O2 and the liquid 3 contained in the mixture 4 is burned in the flame 7. Further the particles 2 of the raw material are made to a fused or semifused state while passing through the flame 7 and thereafter discharged to the outside of the flame 7, cooled and stored in a recovery vessel 8 as spherical ceramic particles 20. Meanwhile since the particles 2 are projected into the flame 7 independently at individual single particle, bulking phenomena due to bonding between the fine ceramic particles is hardly caused.

Abstract: PURPOSE: To produce a permanent magnet excellent in magnetic property through the inhibition of oxidation of a rare earth cobalt system intermetallic compound at crushing, molding and storage process by crushing thereof together with an antioxidant dissolved in a solvent to a fine powder.  
     CONSTITUTION: An intermetallic compound such as RCo 5  or R 2 Co 17  system (R is a rare earth element such as Sm) is roughly crushed into pieces of 1 mm in size. The compound thus crushed, a powdery heat-volatile antioxidant (nitric acid system) and methanol as a solvent for the antioxidant are put into a pot for an oscillating ball mill and then, the mill is actuated. The intermetallic compound is crushed to a fine powder of a few micron meters in size. Then, the methanol is allowed to evaporate. The compound is molded by press in a magnetic field. Subsequently, the compound thus molded is heated to 200°C or more in a vacuum to evaporate the antioxidant. The vacuum is filled with Ar gas and the compound is sintered. In such a manner. no oxidation takes place on the powdery material at any process, providing a highly efficient permanent magnet excellent in magnetic property.

Title: Heating method in two-chamber box annealing furnace
Inventor: SEKIGUCHI KATSUMASA
IPC: C21D9/52
Filed: 1981-09-04
Abstract: PURPOSE:To prevent excessive annealing and to considerably enhance the fuel unit by dividing burners into a plurality of zones and extinguishing them in steps to carry out temp. control. CONSTITUTION:Burners 5 in the heating chamber of a box annealing furnace are divided into 3 zones A, B, C. The burners in the zones A, B, C are fully opened and fuel is burned until the internal higher temp. part of the furnace reaches 720 deg.C. When the part reaches 720 deg.C, to control the temp. of a coil the burners in the zone C is extinguished, and when the cold point of the coil  reaches a temp. 30 deg.C below the desired cold point, e.g., 680 deg.C, all the burners are extinguished. The coil is allowed to stand in the heating chamber, and the heating effect of the furnace due to the potential heat is utilized. By allowing the coil to stand for about 2hr, the cold point of the coil increases by 30 deg.C and reaches the desired value. The coil is then transferred to the cooling chamber.

Title: Operation control device for freezer
Inventor: INOUE TSUGUNORI
IPC: F25B47/02
Filed: 1992-05-29
Abstract: PURPOSE:To prevent a high pressure cut in a freezer device at the time of energization of a compressor or a cycle changing-over operation while the freezer device is of an accumulator-less structure. CONSTITUTION:There is provided a refrigernt circuit 9 having a cycle changing-over mechanism 2 and then a receiver 4 is arranged. There is also provided a bypassing passage 4a for connecting an upper part of the receiver 4 with a liquid line corresponding to a downstream end of a pressure reducing valve 5 through an opening or closing valve SV. As the high pressure side pressure becomes more than a predetermined value by an opening or closing control means of energization when the compressor 1 is energized, the opening or closing valve SV in the bypassing passage 4a is opened. With such an arrangement, a gas pressure within a receiver 4 is reduced, a flow of refrigerant from the condensor 6 (or 3) to the receiver 4 is made smooth to prevent a high pressure cut there. When a freezing cycle is changed over, the electrical expansion valve 5 and the opening or closing valve SV are closed for a specified period of time by the valve control means 53 at the changing-over time, thereafter the electrical expansion valve 5 is opened by a small angle for a specified period of time and the opening or closing valve SV is opened. With such an arrangement, increasing of high pressure is restricted and the liquid back flow is prevented.
