Title: Rotary compressor
Inventor: TOMITA MASAKAZU
IPC: F04C18/344
Filed: 1981-06-08
Abstract: PURPOSE:To prevent leakage of gas and seizure of vanes, by dividing a sliding vane into a plurality of parts so that a plurality of sealing lines can be obtained, and arranging the plurality of sliding vane parts to be slidable relatively to each other along a dividing surface or surfaces. CONSTITUTION:According to the present invention, a first vane 40 and a second vane 41 superposed on each other are so disposed in place that they urged into contact with a piston 17 by a spring 23. Resultantly, two sealing lines for separating a suction chamber 27 from a compression chamber 28 can be obtained. Here, since these two vanes 40, 41 are designed to be slidable relatively to each other and disposed in the same place, they are slided substantially in the same way along with rotation of the piston 17. By thus employing a plurality of vanes superposed on each other, it is enabled to reduce leakage of coolant gas to a great extent since pressure difference on the opposite sides of respective vanes can be reduced.

Title: Volatile storage device applying countermeasures to nonvolatilization
Inventor: YAMAOKA AKIRA
IPC: G06F3/08
Filed: 1987-04-10
Abstract: PURPOSE:To shorten the time needed for data saving recovery when a power supply is interrupted or in an initialization state, by providing a flag control part and setting/resetting a flag provided in response to the region of a volatile memory means. CONSTITUTION:A flag is provided in response to the region of a semiconductor memory part 22 and a flag control part 25 sets and resets the flag in response to the signals received from a processor 1. A control circuit 23 transfers data to a magnetic disk memory part 24 from the part 22 at every region in response to the signals received from the part 25 when the power supply of a memory 2 is interrupted or in an initialization state. Then the data are selectively transferred between the area of the part 14 and the part 22 in response to the set flag. Thus it is possible to apply the countermeasure to nonvolatilization only in a minimum necessary region at each time point in response to the progress state of a program. Then it is possible to shorten the time needed for data saving recovery when the power supply is interrupted or in the initialization state.

Title: Production of cinnamic acid ester
Inventor: WADA HIROSUKE
IPC: B01J23/44
Filed: 1984-04-28
Abstract: PURPOSE:To recover and reuse the expensive Pd catalyst, in high efficiency, in the production of a cinnamic acid ester by the carbonylation of styrene in an alcohol in the presence of Pd or its compound as a catalyst, by removing the alcohol and water from the reaction system by distillation, and adsorbing the Pd to a carbonaceous carrier. CONSTITUTION:A cinnamic acid ester is produced by reacting styrene with carbon monoxide and oxygen in the presence of an aliphatic alcohol using Pd metal or its compound as a catalyst. In the above process, the aliphatic alcohol in the reaction liquid and the most part of water produced by the reaction are removed by distillation, and the Pd metal or its compound remaining in the reaction liquid is adsorbed to a carbonaceous carrier (preferably activated carbon) and reused. The most part of the catalyst component can be recovered as a solid by evaporating the alcohol and water, and the recovery of the catalyst can be remarkably improved.
Patent JP-S60230877-A (JP)
Title: Rubber roller
Inventor: NOMA HIDEYUKI
IPC: B41J11/02
Filed: 1984-04-28
Abstract: PURPOSE:To prevent metallic sound from being generated due to impacts and corrosion resistance from being deteriorated due to rusting, by a method wherein a shaft molded from a bulk molding compound (BMC) is covered by a rubber material. CONSTITUTION:A BMC obtained by incorporating a reinforcing material into a blended resin prepared by dispersely mixing a thermoplastic resin into a matrix of an unsaturated polyester resin is molded to form the shaft 4, which is then covered by a rubber material. The sound generated by an impact on the molded BMC body is in a low frequency region, and generation of a standing wave in the shaft body can be prevented by setting the length of the body to be relatively small, so that harsh metallic sound is prevented from being generated, and the musical scale and volume of the impact sound can be lowered. In addition, since the shaft body molded from the BMC by injection molding or the like also has excellent corrosion resistance, the rubber obtained by covering the shaft body by a rubber is light in weight and is free of danger of corrosion due to rusting.

Title: Method for dephosphorizing molten iron
Inventor: SEKINO KAZUTO
IPC: C21C5/46
Filed: 1995-03-20
Abstract: PURPOSE: To stably melt a high-Mn steel by mixing manganese ore into a converter slag, pre-reducing them and using the reduced converter slag increased in Mn content for dephosphorization, thereby increasing Mn concn. in molten iron simultaneously with the dephosphorization. CONSTITUTION: The manganese ore or an iron-manganese ore is mixed into the converter slag discharged from a converter after decarburize-blowing. At this time, the mixture of the manganese ore or the iron-manganese ore is pre- reduced and pre-smelted by the high retention heat (waste heat) held in the converter slag at the time of removing the slag to obtain the converter slag containing high Mn content. This converter slag is used as the main component of a refining agent in a dephosphorizing furnace. Thus, reduction heat at the time of executing the smelting reduction (endothermic reaction) of the ore in the dephosphorizing furnace is reduced by the quantity executing the pre- reduction of the ore in comparison with the case of directly charging the manganese ore into the dephosphorizing furnace.  Further, the increase of the Mn content to be charged into the dephosphorizing furnace is prevented and the ore in the dephosphorizing furnace is prevented, from being melted insufficiently to improve the Mn yield.

Title: Device for automatic exposure to x-rays
Inventor: IKEDA MITSURU
IPC: H05G1/44
Filed: 1981-06-08
Abstract: PURPOSE:To execute automatic exposure to X-rays while eliminating the drifts of the offset levels of preamplifiers for a photosensor, by storing the offset levels of the preamplifiers to intermittently cancel the offset levels during the non-irradiation of the X-rays and by using the offset levels stored just before the irradiation of the X-rays, to cancel the offset levels during the irradiation. CONSTITUTION:An AND gate 20 is opened by a signal which is for stopping the irradiation of X-rays for seeing-through. The output of a cancel signal generator 21 is sent out through an AND gate 19 to drive a memory controller 18. The outputs of preamplifiers 12A-12N connected to a light intake section 6A undergo AD conversion at 15A-15N to produce signals, which are stored in memories 13A-13N. The stored signals undergo DA conversion at 16A-16N to generate signals, which are changed by polarity inversion circuits 17A-17N. The outputs of these inversion circuits are applied to amplifiers 14A-14N to cancel the offset levels of the preamplifiers 12A-12N. Such operation is repeated during the non-irradiation of the X-rays. During the irradiation of the X- rays for seeing-through or photographing, the storage into the memories 13A- 13N is stopped and the signals stored just before the stoppage are used to cancel the offset levels to enable accurate measurement.
