Title: Reflection type photointerrupter
Inventor: NEMOTO HIROSHI
IPC: H01L31/12
Filed: 1986-06-27
Abstract: PURPOSE:To improve a reliability by enabling an operation to be continued by other light emitting devices even when one light emitting device fails by dividing one end of a projecting optical fiber bundle into a plurality of branches and providing the light emitting devices adjacently to the ends of the branches. CONSTITUTION:The distal end of a projecting optical fiber bundle 3' branches into 3a and 3b, and LEDs 4a and 4b as light emitting devices are provided adjacently to branch ends. Light from the light emitting devices 4a and 4b is irradiated on the gear 2 of a rotating body 1 via the fiber bundle 3'. Reflected light from the gear 2 is inputted to a phototransistor 7 via a light receiving optical fiber bundle 6. Signals converted to electric signals by the transistor 7 are converted to voltages on the basis of the crests and bottoms of the gear 2 to obtain rotational signals. Even when either one of the light emitting devices fails, the operation is continued by the other light emitting device, so that a reliability can be improved.

Title: Dialysis device unit
Inventor: REONAADO DORISUDEERU CHIYANBAA
IPC: A61M1/14
Filed: 1990-06-07
Abstract: PURPOSE: To enable used salt water to be processed cleanly, easily, and safely by providing the unit with a waste outlet configured to be capable of sealably operating in conjunction with a provided pipe set. CONSTITUTION: In use, a fluid, whether it is, e.g. water, a dialytic solution, or bleach, always flows through a dialyzer 10. This waste fluid always flows through a T-pipe 110, a pipe 112, and a venturi tube 106 and goes out of an outlet conduit. A valve device 54 is seated inside a waste outlet 32 except when priming is performed by filling the dialyzer and a pipe set with salt water. The action of a spring 22 to pull a handle 16 downward engages the lower surface of the small-diameter part 72 of a shank 68 with the counterbored hole of the waste outlet 32, moving the shank 72 upward and releasing an O-ring 76 from valved engagement with an inclined surface part 78. When priming of salt water is desired the handle 16 is moved upward and rotated so that a cap 44 can be inserted.  In this case, the action of a spring 80 allows the O-ring 76 in the valve device 54 to close a valve, stopping the flow in a circuit.

Abstract: PURPOSE:To obtain a grade discriminating device capable of highly accurate discrimination based on a certain criterion by photographing and binarizing the prescribed part of a salmon, obtaining the total sum of an area of logic ''1'' or ''0'', comparing it with a set value and discriminating a grade. CONSTITUTION:When a salmon 1 on a conveyor 2 is detected by a position sensor 3, a discriminating device 7 gives instructions of fetching a picture into a camera 5 and checks the attitude and size of the salmon. A discriminating device 8 fetches an area picture three times with the aid of the output of a photoelectric sensor 4, binarizes the picture signal to form a black/white binary picture and obtains its area S by counting the number of picture elements of, for instance, a white area. Said area value is integrated by part, and its integrated value SIGMAS is given to a discrimination controller 9. Then the value is compared with each set value, and a grade is discriminated. The discriminated output from the discrimination controller 9 is given to an actuator 10, branched at each containing part in accordance with the grade, and salmons of the same quality are collected at the same containing part.

Title: Operating knob loading providing mechanism
Inventor: YOSHIDA EIJI
IPC: G05G7/00
Filed: 1995-06-16
Abstract: PURPOSE: To provide an operating knob load providing mechanism to provide a load so that an operating knob is not freely turned. CONSTITUTION: A gear 30c meshing with a gear 35a of a damper 35 is formed to an outer circumference of a right channel recording knob 30. The load of the damper 35 is delivered to the right channel recording knob 30 via the gears 35a, 30c. Since the diameter of the gear 35a is larger than that of the gear 30c, the load of the damper 35 is delivered to the right recording knob 30 while its number of rotations is reduced by the gear ratio of the gears 35a, 30c. Since the load of the damper 35 is always provided to the right channel recording knob 30, even when a guard 30a is touched in mistake during recording, the right channel recording knob 30 is not turned thereby preventing fluctuation in the recording level.

The alloy may contain 0.1W10% of on more of Mn, Y, Cu, Zn, Al, C, rare metals, Ru, Rh, Pd, Os, Ir and Pt as additional components. Its complex magnetic property is obtained by solution-treating the alloy in an α+γ dual phase zone and utilizing the spinodal decomposition of each phase, a γ→α' transition mechanism and an age-precipitation-hardening mechanism so that mainly α contributes to a large coercive force while γ contributes to a small coerive force. Thus, the magnetic alloy having mass-producibility is produced at a low cost.

IPC: H01L31/02
Filed: 1983-08-17
Abstract: PURPOSE:To enhance the practical use in an electronic device with a solar battery having sound generating function by driving a sound generator drive circuit by excess power at high illumination time. CONSTITUTION:In an electronic device with a solar battery for a portable calculator, an LSI circuit 1 is driven through a series resistor 3 by a solar battery power source 2.

Filed: 1989-06-13
Abstract: PURPOSE:To detect a mechanical external force with a high precision by leading the induced voltage of the secondary winding to an electric circuit to take out only the voltage change due to an external force. CONSTITUTION:The elastic pressing force of a coiled spring 5 fixes a circular thin plate 3 and a thin film 4, and the elastic pressing force of the spring 5 to the thin plate 3 which is displaced by the fluid pressure introduced from a pressure introduction port 7 can be cancelled weakened, and it can be operated with a minute pressure from the introduction port 7 of a case 6. The voltage of an oscillating circuit 8 is connected to a winding 2 of a detector 9, and a voltage is generated in a winding 1 and is converted to a DC by a detecting and smoothing circuit 10 and is inputted to an inverted input 15 of an arithmetic circuit 11 and is amplified and is led to an output terminal 13. A variable resistor 12 is so controlled that the voltage of an uninverted input 16 of the circuit 11 is equal to the voltage of the input 15 at the time of not applying a pressure to the detector, and thereby, the voltage of the terminal 13 is 0 when the pressure of the detector is 0, and a positive or negative detection voltage is obtained from the terminal only at the time of applying a pressure to or reducing the pressure of the detector. Consequently, the mechanical external force is detected with a high precision.
