Title: Vacuum processing unit
Inventor: OSHIO KOSUKE
IPC: B01J3/03
Filed: 1984-07-31
Abstract: PURPOSE:To eliminate the need for accurate concentricity at the center of revolution by a method wherein a load-dispatching shaft is sealed tight and rotatably supported by a bearing on the axle of revolution, the bearing is provided on the surface of a vacuum vessel with the intermediary of bellows, and one of the load-dispatching shaft is in contact with a load- dispatching member located outside the vacuum vessel. CONSTITUTION:A load-dispatching shaft 7 is provided on the central axle of a revolving platform 3. The lower end of the load dispatching-shaft 7 goes through a dielectric film 8 and is connected to an elecrrode 6, and the upper end abuts against a load-dispatching electrode located outside a vacuum vessel 1. The load-dispatching shaft 7 is covered by an insulating shaft 14. The shaft 14 is sealed tight by and is rotatable on an O-shaped bearing 16 provided with the intermediary of bellows 15, and is supported on the upper surface of the vacuum vessel 1. A disk 18 provided with a claw 17 is fixed secure to the upper surface of the O- shaped bearing 16, and is supported by a thrust bearing 19. The claw 17 is linked to a stopper 20 for the prevention of revolution. In a unit designed as such, high accuracy is not demanded in the process of installing the insulating shaft 14. Deviation due to eccentric revolution is absorbed by the bellows 15 and thrust bearing 19, keeping the bearing 16 steadily sealed tight. The bellows 15 is impeded by the thrust bearing 19 from shrinkage attributable to exhaust gas.

Abstract: PURPOSE:To effectively prevent a deposition of alumina to a nozzle from molten flow, by providing a lining, consisting of ion-conductive solid-electrolyte refractory porcelain, on the inner circumference of the nozzle to impress an overvoltage between the inside and outside surfaces of the lining. CONSTITUTION:A stepped enlarged hole 4 is formed at the top opening of a dipping nozzle 2 consisting of alumina graphite (AG) porcelain, etc., and facing the bottom of a tundish 1.

Title: Noise transmission checking circuit for power source system in integrated circuit
Inventor: NUKIYAMA TOMOJI
IPC: H01L21/822
Filed: 1988-06-28
Abstract: PURPOSE:To seek to avoid effect of a noises by providing resistance element and a specific bipolar transistor. CONSTITUTION:Since a serial resistance element Z, is set already to a resistance value enough small by a P-channel MOS transistor P1, etc., logical amplitude to power source voltage VDD can be obtained through the transistor P, even when a CMOS inverter buffer outputs positive logical value '1' to O1. To the change of the output Q1 from the positive logical value '0' to '1', the charge is supplied to load capacity C1 through the transistor P1, while also drawing out the base changes of the element Z1, and the pnp type bipolar transistor Q1, but that between the emitter and the base of the transistor Q1 reaches base saturation area. For the emitter voltage value Ve of the transistor Q1, the same value as VDD is enough, and even if the same kind of circuit constitution is adopted to plural noise generation sources, the effect of noise falling on the voltage system Ve can be softened. As all the noises are absorbed in the Ve system, the effect of the noise can be avoided.

Title: Novel d-aminoacylase and production thereof
Inventor: MORIGUCHI MITSUAKI
IPC: C12R1/05
Filed: 1987-06-29
Abstract: PURPOSE:To produce D-aminoacylase in high efficiency without forming L- aminoacylase, by culturing a bacterial strain belonging to Alcaligenes genus and separating D-aminoacylase from the cultured product. CONSTITUTION:A bacterial stain belonging to Alcaligenes genus and capable of producing D-aminoacylase is cultured in a medium containing an inducing substance such as N-acetyl-DL-methionine and the objective D-aminoacylase is separated from the cultured product. A concrete example of the bacterial strain is Alcaligenes denitrificans subsp. xylosoxidans MI-4. The strain solely produces D-aminoacylase and does not produce L-aminoacylase and, accordingly, the strain is useful for the industrial production of D-aminoacylase.

Title: Photoswitch by photoelasticity
Inventor: UEDA MASAO
IPC: G02F1/19
Filed: 1984-07-31
Abstract: PURPOSE:To eliminate the malfunction due to soil of a photoswitch by inserting a light medium changing its degree of polarized light by external force between polarizing filters at I/O sides, and providing an opening of an optical fiber on the surface opposite to the polarized light filter. CONSTITUTION:An input side polarizing filter 1a permits only a plane of polarization D1 in one direction to incident into a light medium 2 among light beams from a light emitting element 3 for including a plane of polarization D0 in several directions. Since a plane of polarization D2 of an output side polarizing filter 1b is different from the plane of polarization D1 by 90 deg., its light will not pass through the filter 1b. Here, when a pressure P is applied to a photoswitch 11, the degree of polarized light of the light medium 2 changes by pressure to output the light to the output side of the switch, and said medium 2 leads the light to a photodetector 5, and functions as a normally opened node of the switch. If the plane of polarization D1 is initially coincident with the plane D2, the light medium 2 serves as a normally closed node. Consequently, since no part where dust in the air or foreign matters deposite is obtained on a light path, the malfunction due to soil, etc., will not occur, and a stable switch action can be obtained.

Title: Filtering apparatus
Inventor: KUDOU MASASHI
IPC: B01D29/33
Filed: 1978-12-25
Abstract: PURPOSE: To reduce the system capacity of apparatus and the dose irradiated with radiation by providing a member, decreasing the sectional area of flow passage of treated water, in parallel with a tube axis within a porous filter.  
     CONSTITUTION: In a waste liquid treating apparatus of an atomic power plant, a nuclear fuel reprocessing in stitution, etc., a rod 6 mode of SUS having uniform diameter is inserted in the direction of axis into the porous tube filter 4 of a filter main body in such a manner that the rod is not contacted directly with the filter 4. Since circulating water containing suspended clads and flowing into the porous tube filter 4 at constant velocity is passed through the filter having the decreased sectional area, flow velocity is speeded up and flow rate is reduced. The clad removing rate is enhanced by the increased flow velocity. As a residence amount of water within the filter is reduced in proportion to the sectional area of flow passage, the dose irradiated with radiation can greatly be reduced.
