Abstract: PURPOSE:To obtain a constant output of an expansion apparatus by providing with the output detector of the expansion apparatus and a controller for controlling the flow rate of gas which flows from a steam generator to the expansion apparatus with the aid of the signal supplied from he output detector, as an input signal. CONSTITUTION:The output of an expansion apparatus 2 or the output of a power generator 5 as load is detected by a detector 6 and input into a controller 7. When the output of the expansion apparatus 2 exceeds a set value, the driving apparatus 4A of a liquid feeding pump 4 is controlled by the signal transmitted from he controller 7, and the number of revolution of the liquid feeding pump 4 reduces. Then, the amount of condensed liquid which is supplied into a steam generator 1 reduces, and also the amount of gas which is generated in the steam generator 1 reduces, and the output of the expansion apparatus 2 reduces to a constant value. Thus, the output of the expansion apparatus can be controlled constant, even if the heat quantity input into the steam generator is not made constant.

Title: Thin rice gruel boiling-up detector for cooker
Inventor: OYA TAKASHI
IPC: A47J27/00
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To detect the boiling-up of thin rice gruel despite of a simple method and use it as a control signal by constituting a detector in such a manner as emitting a boiling-up signal in detecting the lowering of a detection temperature after continuing a fixed temperature for fixed hours in a state heated to the boiling temperature. SOLUTION: When a rice cooker is operated to cook rice, a gas burner B is ignited and the rice cooling operation is executed while controlled the heating power. The temperature in the cooking pot 10 is raised so as to reach the boiling temperature (100 deg.C) and a temperature sensor S detects the boiling point. When the rice cooking is proceeded, the thin rice gruel is started to be produced in the cooking pot 10. The thin rice gruel is boiled up as bubbles, fills the bottom of the inner lid 21, and then reaches steam escape holes 211, 211 provided in the center of the inner lid 21. After that, when the bubbles of the thin rice gruel touch the temperature sensor S, the detection temperature is reduced temporarily.  The thin rice gruel boiling signal is thus emitted from an output means by lowering of the detection temperature and so it is detected that the inside of the cooking pot 10 is in the boiling state.

IPC: G11B5/127
Filed: 1978-12-25
Abstract: PURPOSE:To obtain a magnetic head for vertical magnetic recording which features a high recording density and writing efficiency by suppressing the diffusion of the vertical magnetic flux with installation of a pair of auxiliary coils at the both horizontal sides of the vertical magnetic pole with the coil wound. CONSTITUTION:Vertical magnetic pole 1 wound with coil3 is provided on recording medium 10 with gap 9 secured between, and the read and write is carried out via the vertical magnetic flux as shown by the arrow mark. In such vertical magnetic recording magnetic head, auxiliary coils 5 and 7 wound around magnetic poles 11 and 13 are provided at the both horizontal sides and under pole 1. And the turning direction of the auxiliary coil is set so that the same pole as the lower polarity (such as the N pole) of pole 1 may be generated at the side of pole 1. The same effect, however, can be obtained without using poles 11 and 13, and the number of turns of coils 5 and 7 will suffice enough with a comparatively small number just to prevent the horizontal diffusion of the magnetic flux of pole 1.

Abstract: PURPOSE:To prevent the occurrence of a pin hole in an X-ray window after using it in the air for a long period by accumulating the preventing film of silicone nitride or the like on one surface or both surfaces of berylium foil forming the X-ray window. CONSTITUTION:The X-ray window of an X-ray diffraction device or the like which permits transmission of an X-ray is formed by accumulating a layer 12 of silicone nitride or silicone oxide on the surface of flat berylium foil, of which both surfaces are polished and thickness is several mum to scores of mum, to the thickness of hundreds Angstrom  to thousands Angstrom  by a CVD method or a plasma CVD method. As silicone nitride or the like has small gas permeability and arrests a reaction occurring between oxygen in the air and impurities in the berylium foil 11, the occurrence of a pin hole in the X-ray window at the time of exposing the X-ray window can be prevented, and the X-ray window can be used for a long period.

Abstract: PURPOSE:To ensure that an image is freely written or deleted on the surface of a sheet without damaging the image by printing the image on the rear of the sheet, if the sheet is transparent or translucent. CONSTITUTION:A paper type sensor 1 is a photointerrupter consisting of a combination of a light-emitting diode 27 and photosensor 28, and the sensor 1 is provided at a paper cassette mounting part of a device enclosure 31. A transparent or translucent sheet such as OHP sheet 29 is loaded in a paper cassette 30. Light enters the photosensor 28 from a light-emitting diode 27 after being transmitted through the sheet 29 and the type of paper is identified. If even a single translucent paper is present in the paper cassette 30, an image cannot be printed on the rear of the sheet as the light is prevented from reaching the photosensor 28. Therefore, the light-emitting diode 27 and photosensor 28 are provided at a halfway position between the paper cassette 30 and a printing part 32. The transparent or translucent sheet can be used as OHP sheet by printing an image with the right and left reversed on the rear of the sheet.

Abstract: PURPOSE:To lower unrequired magnetic field coupling, to prevent th decline of Q and to facilitate design and manufacture by providing a coupling window in one end part or both end parts of a partition plate. CONSTITUTION:Electromagnetic waves from an input loop 8a are magnetic-field-coupled to a TM mode resonance element 1 and an electric field is generated in the elements 1 and 2. The magnetic field component of the element 2 generated corresponding to the electric field is turned to the same horizontal surface the direction of a window 7a, passed through the window 7a and magnetic-field-coupled with the element 3 of the TM duplex mode resonator R20 of the next stage. The electric field is generated in the dielectric of the elements 3 and 4 by the coupling, the magnetic field of the element 4 corresponding to it is intersected to an output loop 8b and output is outputted from the loop 8b. In this case, since a magnetic field surface generated in the element 1 orthogonally crosses with the direction of the window 7a, the magnetic field can hardly intrude inside the window 7a and can be interrupted. Also, since the window 7a is provided in the upper end center part of the partition plate 7, it is considerably separated from the element 1 compared to the element 2 and the magnetic field coupling of the element 1 and the element 4 of the next stage to be unrequired becomes extremely small.
