Title: Cryogenic refrigerating machine
Inventor: MASUDA HIROSHI
IPC: F25B9/00
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To permit maintaining of vacuum condition in a vessel without necessitating any exhaust device operated at all times by a method wherein an adsorption panel, adsorbing the particles of gas in the vessel provided in the cooling unit in the vessel, is provided. SOLUTION: An adsorption panel 8 is fixed to the cold head 32 of a cooling generating unit 3, cooled to a cryogenic temperature, so as to be capable of transmitting heat, and is arranged in a vessel 6. The adsorption panel 8 is cooled to a cryogenic temperature since the cold heat of the cold head 32 is transmitted. As a result, the molecules of gas, generated in the vessel 6, are adsorbed to the adsorption panel 8. Accordingly, the rise of pressure in the vessel 6 is restrained whereby vacuum condition in the vessel 6 is maintained. The surface area of the adsorption panel 8 is increased so as to permit the adsorption of the molecules of gas for a long period of time.  The molecules of gas, generated in the vessel 6, are adsorbed by the adsorption panel 8 whereby the vacuum condition in the vessel 6 is maintained and the deterioration of cooling performance of a matter to be cooled due to the existence of the cooling generating unit 3 is restrained for a long period of time in such a manner.

Title: Bidirectional thyristor
Inventor: OTA KOICHI
IPC: H01L29/747
Filed: 1991-02-08
Abstract: PURPOSE:To prevent a reactive current and to prevent an irregularity in the resistant amount to a surge current by a method wherein a part whose breakdown strength is low as compared with that in other parts of a P-N junction is formed in the P-N junction deciding the breakdown strength in a part at a distance from a short-circuit part. CONSTITUTION:When an impressed voltage is raised and set to the breakdown strength of a low breakdown strength part D2, the whole of an electric current flows through the low-breakdown strength part D2 and no reactive current flows. The electric current causes a voltage drop by the resistance in the transverse direction of an N2 layer, and a junction J4 is biased. This forward bias becomes maximum in a part which is situated directly under the low breakdown strength part D. As a result, the injection of holes from the junction J4 becomes maximum in the part. Since the injection amount of electrons from a junction J2 becomes maximum, a turning-on operation is started from this part. As a result, it is possible to prevent an increase in the reactive current, to limit an initial ignition position and to prevent an irregularity in the resistant amount to a surge current. As the fundamental constitution of the title thyristor, the following are installed: short-circuit parts B1 and C1; and parts D1, D2 whose reverse breakdown strength is low as compared with that of other parts of junctions J2, J3 away from B2 and C2.

Title: Method of producing oxygen
Inventor: FUJITA YUUKOU
IPC: H01M8/18
Filed: 1983-03-07
Abstract: PURPOSE:To facilitate disposal of hydrogen by supplying hydrogen generated during water electrolysis to a hydrogen-air fuel cell and consuming the hydrogen through electric discharge. CONSTITUTION:When water electrolysis is carried out by supplying water from a water tank 1 to a water electrolysis device 2, oxygen is obtained from an oxygen-leading-out hole 3 and hydrogen generated from the water electrolysis device 2 is introduced into an accumulator 4 and stored in it. The hydrogen stored in the accumulator 4 is supplied to a hydrogen-air fuel cell 5. On the other hand, when air is supplied to the hydrogen-air fuel cell 5 and a given load is connected to the cell 5, electric discharge occurs and hydrogen is consumed producing water. The thus produced water is returned back to the water tank 1. Thus only oxygen is obtained in total.

Abstract: PURPOSE:To surely perform a defect inspection of a photomask or the like for LSI with an automatic inspector by an adjacent chip pattern comparing system for forming adjacent chip patterns in vertical or horizontal arragement by projecting different reticle patterns. CONSTITUTION:In a defect inspection of a photomask formed by repeatedly arrangeing chip patterns of the same shape in a plurality of vertical and horizontal lines on a mask substrate, reticle 31 is prepared by forming two chip patterns A, A' 33 of the same shape on glass substrate 32. Using reticle 31 the 1st vertical line 35 and the 2nd vertical line 36 are formed in order on photomask forming substrate 34 by means of a photoreceptor while shifting patterns 33 by one chip pattern. A plurality of lines are formed in a similar way. Since there is little probability that reticle patterns A, A' have the same defect, the automatic inspection of the resulting photomask is surely performed by comparing adjacent patterns.

IPC: D21H27/00
Filed: 1989-02-20
Abstract: PURPOSE:To drastically decrease curling after heat fixing by specifying the longitudinal wave propagation speed ratio of the ultrasonic pulse expressed by the propagation speed in a machine direction to the ultrasonic propagation speed in a cross direction to 1.00 to 1.25. CONSTITUTION:This paper is so formed that the longitudinal wave propagation speed ratio of the ultrasonic pulses of the paper expressed by the propagation speed in the machine direction to the ultrasonic propagation speed in the cross direction is within a 1.00 to 1.25 range as a result of the investigation made in terms of the fiber orientability of the paper. The transfer paper adjusted to this range of the longitudinal wave propagation speed ratio is drastically lowered in the dehumidification shrinkage in the cross direction and is greatly decreased in the curling value after the heat fixing of the ordinary transfer paper. The results of the figure indicate that there is no directivity in the fiber arrangement as the longitudinal wave propagation speed ratio of the ultrasonic pulses is nearer 1.0. The transfer paper which is decreased in the curling after the heat fixing is obtd. in this way.

IPC: G06M9/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To easily and accurately count packets of paper monies stored in a paper money storage box such as a safe without any human intervention and to determine and secure the count by combining the count result of a packet counting means provided inside with the movement quantity of the packet counting means, i.e., a position detection result. SOLUTION: A count sensor 113 arranged opposite the band of a packet P is moved up and down along a rail 114 and then light and dark at a break between the bands of packets P stack in the packet safe 83 are read to determine the number of packets P. When an encoder 124 engaging a speed reduction gear 122 of a driving part 118 rotates, light reaching a photoelectric converting element through its slit is interrupted, and consequently it is possible to detect the rotation of a motor 121, namely, measure the movement distance of the count sensor 113. Therefore, even when a reflection sensor of the count sensor 113 is unable to read the band, the number of packets P can be determined according to the movement distance of the count sensor 113 detected by the encoder 124.

Filed: 1993-02-26
Abstract: PURPOSE:To improve the fuel consumption and reduce NOx by evaluating the combustion state of the engine by the combustion index to be defined by using a small quantity of information on the pressure in detected cylinders, and thereby realizing the lean combustion critical control. CONSTITUTION:An intra-cylinder pressure detecting means 21 measures the intra-cylinder pressure at three points in total including two in compression stroke and one in expansion stroke by the signals from an intra-cylinder pressure sensor 17, and a crank angle sensor 15. A combustion index computing means 22 computes the combustion index Cio to be defined by the specified expression by using three detected intra-cylinder pressures. As for this Cio, when the combustion has a margin, the combustion index Cio which is larger than the value Cios is concentrated at the approximtely constant engine output. In the lean combustion critical condition, the combustion index Cio starts to be slightly dispersed, and when the lean combustion critical condition is passed, the combustion index is dispersed to the range where the engine output is low. This constitution allows the judgement of the combustion condition.
