Title: Heat transfer system
Inventor: MABUCHI MINORU
IPC: F28D15/02
Filed: 1986-06-06
Abstract: PURPOSE:To permit the effective utilization of a low-temperature heat source as well as the heat transfer over a long distance and reduce restriction in installation by a method wherein a refrigerant transfer tube, constituting a closed loop in which vapor from an evaporator is supplied to a heat radiator provided at a position higher than the evaporator while condensate from the heat radiator is introduced into the evaporator by its own weight, is equipped in the titled heat transfer system. CONSTITUTION:Refrigerant, suitable for a heat source 19 to be used, is determined and is poured into an evaporator 1 from a refrigerant supplying unit 4 through valves 3, 2 exclusive for the refrigerant until the pressure thereof arrives at a predetermined pressure. The evaporator 1 receives heat from the heat source 19 to vaporize the refrigerant into vapor. The vapor is supplied into a radiator 8 through a refrigerant transfer tube 7. In the radiator 8, the vapor radiates heat and is liquefied. Condensate generated in the radiator 8 is transferred by the refrigerant transfer tube 7 and returns to the evaporator 1 through a receiver tank 15, an auxiliary heat source 16 and a pressure gauge 18 exclusive for the refrigerant sequentially. Predetermined heat radiation is effected from the radiator 8 by repeating the same operations. According to this method, the low-temperature heat source may be utilized effectively, heat transfer over a long distance may be effected, thus reducing restrictions in the installation of the title system.

Title: Sheet processing device and image forming device
Inventor: HONMOCHI HIROKI
IPC: B65H31/00
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To preventing bending of a sheet mounted on a sheet path by bending a conveying passage below a vertical sheet path carrying a conveyed sheet in the direction crossing the conveying direction at right angles and generating conveying directional stiffness in the mounted sheet. SOLUTION: After a pickup roller 69 is separated, driving rotating of driving roller 68 is maintained. In this process, a contact pressure between a conveyed sheet and the driving roller 68 is not so intensive that weak conveying force based on this contact is given. In this way, the sheet is surely conveyed to a stopper 62 and pressed to it so as to be surely aligned. In a conveyance center position of a bundle of sheets aligned to a vertical path by means of a supporting plate fixed in a frame, a stapler unit 61 is arranged in an objective position with reference to its width direction. Between the upper and lower parts of the stapler unit 61, the vertical path is bent in the vertical direction in the center of the sheet.  That is, the sheets are stacked with their lower parts bent in the lateral direction and their substantially central parts bent in the vertical direction, so that generation of buckling can be prevented.

Title: Field effect transistor
Inventor: MIYAMOTO HIRONOBU
IPC: H01L29/812
Filed: 1993-06-01
Abstract: PURPOSE:To provide a field effect transistor having a smaller gate leakage current and a higher gate withstand voltage, in a field effect transistor containing In. CONSTITUTION:In a transistor having an InAlAs layer under a gate electrode, this field effect transistor is characterized in that it has a first semiconductor layer with electron affinity smaller than that of the InAlAs layer in the InAlAs layer directly under the gate. Since the InAlAs layer 5 exists on the first semiconductor layer 4 having electron affinity smaller than that of the InAlAs layer, yield can be raised when an n-type InGaAs layer 6 for forming the gate electrode 7 is removed by etching, and the etching can be stopped by the InAlAs layer 5 being the upper layer leaving the first semiconductor layer behind. Accordingly, it becomes possible to obtain a field effect transistor having a smaller gate leakage current and a higher gate withstand voltage with a good yield and good reproducibility.

Abstract: PURPOSE:To obtain a radiation picture information reader and a scanning type fluorescent microscope whose resolution can be improved by using a linear polarization as an excitation light, and providing an analizer which allows only the linear polarized component of an accelerated luminous light to pass. CONSTITUTION:An excited light whose vibration direction is a K direction is made incident to a mirror 16. The excited light whose light is in a parallel state is converged on a fine optical point P on a storage phosphor sheet 18 by an objective lens 17.

This luminous flux is reflected on the mirror 16, a part is reflected on a dichroic mirror 13, transmitted through an analizer 20, condensed by a condenser lens 24, and image-formed on a point image Q. The light quantity of the point image Q is detected by a photodetector 25 such as a photomultiplyer. The vibration direction is made to be random at a diffusion part except a part near to an excitation irradiation point, and the influence of the pertinent diffusion is removed by the analizer 20, so that the resolution can be improved.

IPC: G05B11/28
Filed: 1979-10-08
Abstract: PURPOSE: To exercise efficient control by carrying out calculation in two parts within limited time according to contents of a control parameter.  
     CONSTITUTION: Minimum value T w min. and maximum value T w max. at on time T w  are known. Then, T w  is in inverse proportion to a power voltage and the time required for calculation is short. Since off time T f  is determined by various parameters, the time required for calculation is long. Immediately after the control is turned on at time t 1 , calculation of T f  is started. The calculation of T f  is interrupted temporarily after T w min. so as to calculate T w , but T w  is determined in a short time. As a result, the control is turned off at time T 3 . The calculation of T f  is restarted after T w max., it is completed at time T 5 , and the control is turned on at time T 6 . Time T 5  is determined by the time required for the calculation, so that time T 6  will be found by subtracting a certain time out of T f .
