Abstract: PROBLEM TO BE SOLVED: To improve the exciting light absorbing efficiency of an optical amplifier or a laser oscillator using an optical waveguide containing Pr in its core plate as an amplifying medium and having a specific wavelength band by using two kinds of exciting light rays as an exciting light source. SOLUTION: When an optical amplifier or a laser oscillator using low-phonon glass, such as the halide glass, chalcogenide glass, halide oxide glass, or chalcohalide glass containing about 1,000-10,000 ppm Pr as the core of its optical waveguide is made to make optical amplification or laser oscillation in 1.3 μm band, a combination of exciting light rays having two kinds of wavelengths of 1.7-1.8 μm and 1.4-1.6 μm or 1.7-1.8 μm and 1.8-2.0 μm are used. Since excitation can be made from a base level to 3F2 and, further, from a state where de-excitation is made to 3H6 by nonradiative relaxation to 1G4, the exciting light absorbing efficiency of the optical amplifier or laser oscillator can be improved about tenfold.

Title: Control device for refrigerator
Inventor: YOSHINO YASUHIRO
IPC: F25D11/00
Filed: 1988-12-20
Abstract: PURPOSE:To make it possible to cut off consumption power loss and increase cooling speed after the restarting of a compressor by providing a control means which changes the rotary speed of said compressor so that a pressure value on a higher pressure side in a refrigeration circuit may exceed a preset value before halting the operation of said compressor. CONSTITUTION:A detected temperature and a preset temperature inside a refrigerator are read into a control means 3 from detections means 1 and 2 where differential temperature is calculated. When differential temperature is judged to be smaller than a preset value and a compressor 5 is forced to end its operation very soon, signals detected by pressure detection components 8a and 8b are incorporated into a pressure detection means 8 where a differential pressure between a high pressure side and a low pressure is calculated and the calculated value is compared with a preset value, thereby changing the rotary speed so that a pressure value on a higher pressure side in a refrigeration circuit before suspension may exceed a preset value. This construction makes it possible to maintain the refrigerant after the suspension of the compressor 5 around a state available before the suspension, minimize power consumption after the restarting, and return the temperature inside the refrigerator promptly back to the state before the suspension.

Abstract: PROBLEM TO BE SOLVED: To prevent the magnetic characteristic of a coil wound on a bobbin from changing and to enable high-precision measurement, by putting the bobbin inside an annular recessed groove formed in the top surface of a cylinder head of a non-magnetic substance. SOLUTION: A high-frequency differential transformer type displacement sensor 11 for example to be used in a measuring apparatus which detects the displacement of an engine valve 1 under a firing condition, is put inside the annular recessed hole 12a of the swollen-out part 12 near the press-fit part of a valve guide 3 in the top surface of a cylinder head 2 made of an aluminum alloy for example. This displacement sensor 11 is composed of a cylindrical bobbin 14 having a sensor coil on its peripheral surface, and a core 15 which adheres firmly to a spring retainer 5, etc., and interlocks with the valve 1. Since the sensor coil 13 is put inside the recessed hole 12a, its magnetic characteristic does not change by the movement of a valve spring 7 made of iron, and accurate survey of follow-up to the cam 10 of the valve 1, etc., become feasible.

Abstract: PURPOSE:To accomplish a control method and a control circuit for preventing the deterioration of display quality as to the method and the circuit for controlling a display device such as a plasma display unit, etc., for displaying after a control signal and display data are inputted from a host system. CONSTITUTION:When the display data from the host system 17 is written in a memory 22, a signal XDREQ from the host system 17 to a D type flip-flop 24 is previously made to be at a low level. Thus, the XQ output of the D type flip-flop 24 becomes at a high level, so that a vertical synchronizing signal XVSYNCIN is stopped to be sent out to a plasma display control circuit 3. By stopping the signal to be sent out, display rewriting by the display data read out from the memory 22 is not performed on a plasma display panel 5, the display by the previous frame is maintained. The display data is written in the memory 22 from the host system 17 in this state.

Filed: 1987-12-18
Abstract: PURPOSE:To secure a sufficient lift stroke, by interposing a non-circular gear between a shaft on the side of a prime mover and a rotating shaft of a crank in such a manner that a speed ratio on the side of the crank rotating shaft increases on the side where a slider is at a lowering position. CONSTITUTION:A pair of non-circular gears 14 and 15 are interposed between a rotating shaft 13 of a rotary disc 9 equivalent to a rotating shaft of a crank and a driving shaft 2 or a shaft on the prime mover side such as intermediate shaft 12 receiving a power therefrom 2. The gears 14 and 15 are so designed in the shape that a speed ratio of the gear 14 on the side of the rotating shaft 13 becomes small relative to the gear 15 on the prime mover side on the side where a slider is at a rising position, while it becomes larger on the side where the slider is at a lowering position. As a result, a lift stroke of the slider reaches a sufficiently large value to ensure that an inspection head 5 is inserted sufficiently deep into the inside or the like of a glass bottle quickly during a short stoppage and is pulled up again to a sufficient height thereby securing a sufficient lift stroke.
