Title: Scroll gas compressor
Inventor: FUJIO KATSUHARU
IPC: F04C29/02
Filed: 1996-06-14
Abstract: PURPOSE: To provide a scroll gas compressor provided with low-noise and vibration characteristics and superior compressor starting performance by preventing attenuation of delivery pressure pulsation and propagation of the pulsation. CONSTITUTION: Gas in a delivery chamber 2 is discharged to a motor chamber 6 via an internal path of a closed case 1, an opening part to the motor chamber 6 is opposed to the axial end part of the motor 3 and arranged in a position higher than the oil face of a discharge chamber oil sump 34, while an opening part to the motor chamber 6 is so arranged that the lubricating oil in the delivery chamber oil sump 34 does not flow backward to the compression chamber along with delivery gas through the opening part in an instantaneous inverse turning movement of a turning scroll 18, which is generated by differential pressure between the delivery chamber 2 and the compression chamber right after the stop of the compressor.  This constitution suppresses noise and ill effects on vibration caused by pressure pulsation of the delivery gas path to the motor chamber 6 so as to exhibit low-noise and low-vibration characteristics of the scroll gas compressor and prevents the backward flow of the lubricating oil to the compression chamber in the stop of the compressor so as to provide a smooth starting performance of the compressor.

Title: Method for sampling molten steel in secondary refining process
Inventor: NAKAGAWA KEITA
IPC: G01N1/10
Filed: 1990-06-13
Abstract: PURPOSE:To sample molten steel through a sampling port by holding a cap at a position where slug on the molten steel in a molten steel container is penetrated, and removing the cap when the molten steel is sampled. CONSTITUTION:When slug 3 is solidified or becomes too thick with the elapse of a long processing time, an arm 5 is lifted immediately before sampling, and a cap 4 is removed. Thus, a sampling port 6 for a molten steel sample is formed. Thereafter, a sampler 7 is inserted through the sampling port 6, and the sampling of the molten steel is performed. After the sampling, the arm 5 is lowered, and the cap 4 is returned to the original position. In the next sampling, the cap 4 is removed again. In this way, even if the cover slug in the molten steel container is solidified or becomes too thick, the sampling of the molten steel can be performed without trouble.

Title: Continuous ignition device with alarm
Inventor: MAEDA MITSURU
IPC: F23N5/12
Filed: 1981-09-29
Abstract: PURPOSE:To provide a positive prevention of accident caused by a discharging of non-combustion gas in case that the ignition of gas is not made by a method wherein an alarm is operated just after the gas is ignited, or during a period starting from an ignition of the gas to a successful ignition of the gas. CONSTITUTION:When the gas instrument is to be used, an opening of the gas cock 16 causes each of the switches Sw-1, Sw-2 to be closed and the non-combustion gas to be discharged from the gas burner 17. At this time, one end 4a in the flame rod circuit 4 is at a high potential and transistors Tr1, Tr2 are turned off, the transistors Tr3, Tr4 are turned on and then the blocking oscillation circuit C is operated. Thereby, if a high voltage generating part D is operated, and the burner 17 is ignited under a continuous discharging of the discharging electrode E, the potential in the circuit 4 is decreased, the oscillation circuit C, high voltage generating part D are terminated and at the same time the transistor Tr1 is turned on, the transistor Tr5 is turned off, the transistor Tr6 is turned on and the buzzer 14 is operated by the driving circuit G. This operation is confirmed, the ignition is terminated and the buzzer 4 is terminated.

Title: Channel switch circuit network
Inventor: INOMATA TETSUO
IPC: H04Q3/52
Filed: 1979-11-29
Abstract: PURPOSE: To reduce the number of components, by selecting the switching elements for incoming line with one selection signal and the switching elements for outgoing line, in the balanced channel switch circuit network using PNPN switching elements.  
     CONSTITUTION: When the selection signal y 2 C is selected with the decoder V cy , PNPN elements S 21 R, S 22 R...S 2m R are selected. On the other hand, when the selection signal X 2 C is selected with the decoder VCX, PNPN elements S 12 T, S 22 T... S n2 T are selected. Thus, only cross point switches S 22 R, S 22 T are driven, and the telephone set ST 2  is connected to the line via the trunk TRK 2 . Then, in comparison with the selection of cross point switches through the AND condition of both the selection signals X, Y conventionally, the AND circuit is made unnecessary, and the number of components is reduced, allowing to reduce the power consumption and to lower the cost.

Filed: 1987-06-22
Abstract: PURPOSE:To decrease draft resistance in curved parts, to utilize the heating surface of curved parts effectively, and to increase heat transfer coefficient, by determining the fin pitches of the inside rows of curved parts larger than those of the outside rows of curved parts. CONSTITUTION:In a heat exchanger 17 before curved parts are formed in a heat exchanger 11, the fin pitches fP11 of curved parts A of a group of fins being inserted into a group of heat exchanger tubes 13 which are to be the inside rows of curved parts are determined larger than the fin pitches fP12 of the other parts. Accordingly the fin pitches fP13 of the inside rows of curved parts A are larger than the fin pitches fP14 of the outside rows of curved parts A in the heat exchanger 11, and draft resistance at the time when air passes through the curved parts A is decreased. Therefore the air rate passing through the curved parts A increases, the curved parts A can be utilized effectively as heating surfaces; as a result, the heat transfer coefficient to a heat exchanger can be increased.

Title: Method for operating base station in phs communication system
Inventor: HAYASHIDA ATSUSHI
IPC: H04W48/06
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To provide an operating method for base station which can avoid concentrated position registration of many mobile stations to a specific base station in a PHS(Personal Handyphone System) and also prevent a long time from being needed to process the origination and termination of mobile stations on the whole in the PHS communication system. SOLUTION: When the number of mobile stations whose positions are registered to a base station exceeds a prescribed number, a PHS exchange sends an origination- only command to the base station (step S5), which changes its operation state from a normal operation state to an origination-only operation state; and the mobile stations whose positions are registered to the base station change their base station as the position registration destination.  Then the PHS exchange sends an origination-only reset command (step S10) when the number of mobile stations whose positions are registered to the base station decreases below the prescribed number and the base station changes (resets) the operation state from the origination-only operation state to the normal operation state in response to the reset command; and the mobile stations having their positions registered to the base station stop changing the base station as the position registration destination.
