Title: Liquid level sensor
Inventor: MIYAZAKI SEIJI
IPC: G01F23/292
Filed: 1981-03-06
Abstract: PURPOSE:To obtain an inexpensive device with the simple construction work by disposing the terminal parts of a pair of optical fibers having the end faces intersecting diagonally with the axial center by facing each other on the same axial centerline such a way that the end faces assume an open angle. CONSTITUTION:The terminal parts of a pair of optical fibers having the end faces intersecting diagonally with the axial center are disposed by facing each other on the same axial centerline in such a way that the end faces assume an open angle, in a place where the liquid level fluctuates vertically. For example, when the light transmitted through the inside of a core 11 is made incident at the point A on the M-M plane, it refracts and is made incident to the N-N plane at the point B' if the medium around the coupling part is air. Further, it advances by refracting in a core 21, refracts at the point C' on the outside circumference of a clad 22 and advances into the air. If the medium is liquid, it refracts at the point A, is made incident to the N-N plane at the point B, and advances in the core 21, after which it is totally reflected by the boundary face of the core 21 and the clad 22, and further it is reflected totally at the point D and advances in an optical fiber 20. The change in the optical coupling loss between the air and the liquid is measured, whereby the liquid level is known.

Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To provide an infrared laser imaging apparatus removing the infrared radiation of a background without requiring a chopper and enabling imaging only by laser reflection. SOLUTION: An infrared laser oscillator 1 oscillates laser beam at a wavelength matched with the resonance absorbing wavelength of gas ready to be visualized.

A control unit 7 synchronizes the horizontal scanning timing of the laser scanning optical system 2 and the horizontal scanning timing of the electron scanning of a non-cooling imaging element 4. Laser beam is reflected by the target plate 8 and the diffused beam thereof is formed into an image on the non-cooling image element 4 by the image forming lens 3 of an imaging camera and the formed image is read as an image signal from the non-cooling imaging element 4 by a signal processing part 5.

Title: Heat exchanger
Inventor: SAITOU HIDEJI
IPC: F28D1/053
Filed: 1982-03-03
Abstract: PURPOSE:To improve the heat radiating performance of a plate fin type heat exchanger by uniformly dividing a plate fin inserted with a condensing tube into a plurality of segments and separating the tube into a plurality of segments, thereby preventing the sliding bent of the plate fin. CONSTITUTION:A plate fin 4 inserted with condensing tubes 3 is divided in lengthwide L direction, and is set so that the bent amount becomes lower than the specified value in response to the contraction of headers 1, 2. In this case, the tube is also divided. A gap G is formed between the fins 4. According to this structure, even if the heat exchanger is increased in size, the bent amount of the fin 4 can be reduced, thereby stabilizing the heat radiating performance.

Abstract: PROBLEM TO BE SOLVED: To provide a maximum flow regulating valve which can obtain a maximum flow rate, by eliminating a troublesome full-opening operation by a manual operation, and a relatively large-scale and expensive equipment. SOLUTION: This maximum flow regulating valve comprises: a valve casing 1 having an axis C in a vertical direction; a valve 2 disposed in a valve casing 1 to be capable of moving up and down; a valve casing seat portion 1A disposed in an inner circumference of the valve casing 1.

IPC: B23K15/00
Filed: 1986-02-17
Abstract: PURPOSE:To make focusing condition of an electron beam emitted from an electron gun variable, by making it possible to vary a distance between a grid and a cathode by means of oil pressure applied from outside of vacuum in the axial direction of the electron beam. CONSTITUTION:By opening a pressure relief valve 4, insulation oil 15 is extruded by forces of a filament support 12 and a spring 11 so that a filament 10 is pulled in a space behind a grid 9. Also, by closing the pressure relied valve 4 and gradually opening a pressure valve 5, the filament support 12 is extruded toward the hole of the grid 9 and the amount of extrusion is decided by the pressure of the insulation oil 15. In the case when microwelding which requires a small current or deep weld penetration is required, well focused electron beams can be obtained by using the filament 10 slightly pulled in a space behind the hole of the grid 9. Also, in the case of welding with less sputtering is required, stable and better welding can be achieved by adjusting the filament 10 toward the front of the hole of the grid 9.

Title: Hydraulic circuit for automatic transmission
Inventor: UEKI AKIHIRO
IPC: F16H59/68
Filed: 1991-02-04
Abstract: PURPOSE:To prevent the delay of clutch locking by supplying one of plural oil pressures as switching signal pressure to a switching valve, and providing a by-pass passage for by-passing the throttle of an oil pressure feed passage when this signal pressure is lower than the switching pressure of the switching valve. CONSTITUTION:With reverse clutch pressure PR supplied to a port 10c from a reverse clutch as switching signal pressure, a switching valve 10 performs selective communication among ports 10a-10d and ports 10b-10d, and performs communication between ports 10e, 10f at the communicated time among the ports 10a-10d. That is, the ports 10b-10d are communicated with one another when the switching signal pressure PR is smaller than the switching pressure of the switching valve 10, so that high clutch pressure PH is supplied to an accumulator 11, and the reverse clutch pressure PR is supplied directly without passing a throttle. At the reverse time, the ports 10a-10d are communicated with one another so as to supply the reverse clutch pressure PR to the accumulator 11.

Title: Separating and enriching device for oxygen in air
Inventor: TOYOTOMI HIDENOBU
IPC: B01D53/04
Filed: 1983-02-28
Abstract: PURPOSE:To improve the recovering rate of a refined gas and to increase the concn. thereof by separating a storage tank for separated oxygen to two independent tanks on an adsorption cylinder side and a discharging port side and connecting both tanks with a check valve to prevent the backflow of the stored gas from the discharging port side to the adsorption cylinder side. CONSTITUTION:When stored gas flows into adsorption cylinders 1, 1' the inside of which is evacuated in a desorption stage, the gas having the low oxygen concn. in a storage tank 2 flows first into the cylinders but the gas of the high oxygen concn. in a storage tank 3 is prevented from backflowing by a check valve 4 and therefore the inflow of the gas in the tank 3 to the tank 2 and the cylinders 1, 1' is obviated. The backflowing gas is again refined in the adsorption cylinders and is converted to the gas having high purity which is forced again through the tank 2 into the tank 3. There is the effect of increasing the oxygen partial pressure in the adsorption cylinders when the gas in the tank 2 backflows into the cylinders by which the adsorption and separation of raw air is accelerated and the oxygen concn. in the refined gas is increased.
