Title: Controlling method for fluid flow rate
Inventor: HASEGAWA KOICHI
IPC: G05D7/06
Filed: 1995-04-28
Abstract: PURPOSE: To improve reliability/safety by stably, speedily and safely controlling the quantity of an additional component such as smelled liquid to be additionally injected by controlling the rotating number of revolution of a pump or the aperture of a valve so that the deviation of a flow rate can be zero. CONSTITUTION: A relation G between a 'pump output or valve aperture' F and the flow rate of fluid C is found in advance (1), the flow rate of fluid A is measured (2) and a flow rate D of fluid C required for turning the ratio of fluid C to be injected into the flow rate of fluid A to B is calculated (3). Based on this flow rate D, an output signal Z from the relation G to the rotation of the pump or the valve aperture is instantaneously outputted (4), a current flow rate E of the fluid C is measured (5), and the number of revolution of the pump or the valve aperture is controlled so that the deviation between the flow rates D and E can be zero (6).  Therefore, since feedback control with a controllable range limit is utilized for the output signal value Z, the quantity of the additional component such as smelled liquid to be additionally injected to the gas flow of town gas can be stably, speedily and safely controlled.

Title: Heat accumulating device
Inventor: YANATORI MICHIO
IPC: F28D20/00
Filed: 1981-08-21
Abstract: PURPOSE:To enable to collect heat from latent heat accumulating materials or to accumulate  heat in the materials in a short time by a method wherein a plurality of heat accumulating  vessels containing the latent heat accumulating materials of different boiling points, respectively, are disposed within a heat accumulating tank in the flow direction of a fluid in the tank in  such a manner that the vessels are arranged in sequence in the order beginning from the vessel having the heat accumulating material of the lowest boiling point and ending with that having  the heat accumulating material of the highest boiling point. CONSTITUTION:The fluid 8 of low temperature is flowed from an inlet pipe 4 toward an outlet  pipe 5 at the time of heat radiation. In this case, the fluid 8 is heated to an elevated temperature by receiving heat from the heat accumulating materials 2a-2d but since the heat accumulating materials of higher boiling points are arranged in the flow direction of the fluid 8, the  difference in temperature between the fluid 8 and the heat accumulating materials is kept substantially constant with respect to the flow direction of the fluid. As a consequence, the  amounts of heat radiation from the heat accumulating vessels 1 become substantially equal to  one another and the entire amount of heat radiation from the vessels as a whole increases.  Therefore, in case where a large amount of heat is required temporarily, this is extremely  advantageous and hence it is possible to collect heat from the heat accumulating materials or  to accumulate heat in the materials in a short time.

Title: String extruding method of cylindrical shell
Inventor: KANBARA HIDEAKI
IPC: B21D22/10
Filed: 1981-08-21
Abstract: PURPOSE:To perform string extrusion in an optional shape in a short time precisely by arranging and retaining segmental dies at the outside of a cylindrical shell, and inserting a pressing rod equipped with an elastic body into the cylindrical shell and then applying an axial load. CONSTITUTION:For the string extrusion of a cylindrical shell 1, a pressing rod 7 equipped with an elastic body 3 of annular rubber, etc., is inserted into the cylindrical shell 1. Sectional dies 2 each having a prescribed string shape worked in the internal surface are set at the outside of the cylindrical shell 1 facing the elastic body 3 and retained with a retaining rind 9. In this state, highly pressurized oil is fed from a hydraulic cylinder 6 to apply an axial load to the pressing rod 7, and thus the elastic body 3 is compressed to spread in radius directions. Consequently, internal pressure is allowed to operate on the internal surface of the cylindrical shell 1 in radius directions, thereby extruding the cylindrical shell 1 in the shape of grooves worked in the internal circumferences of the segmental dies 2. This method realizes excellent string extrusion in an optional shape.

IPC: H04N5/76
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To effectively find a cassette to be reproduced out of many recorded cassettes with built-in memory. SOLUTION: After a cassette is loaded and it is detected that a tape is existent (S1, S2), information is read out from the memory inside the loaded cassette and displayed on a monitor (S3, S4). If a user does not want to reproduce the cassette based on the displayed information, the cassette is discharged by pushing a take-out button (S5, S6). If the cassette is desired to be reproduced, a reproducing button is pressed to be unloaded and wound around a rotation drum (S7, S8). Accordingly, a wanted cassette can be easily detected without loading and unloading all of the cassettes.
