Title: Device for converting energy of surface wave of liquid into electric energy and its reverse device
Inventor: HORUSUTO RITSUPUMAN
IPC: F03B13/14
Filed: 1995-05-23
Abstract: PURPOSE: To obtain an apparatus for converting the energy of the surface wave of liquid into electrical energy or reversely without using a hydraulically driven generator or any other machine having movable a component by varying the capacitance of a capacitor directly and periodically by a surface wave flowing through charge carriers. CONSTITUTION: A dielectric medium MED is sandwiched by a liquid FL and an ambient gas. The dielectric medium MED is moved vertically through the periodic oscillation of a wave W, thus varying the capacitance C of a capacitor. Consequently, the capacitance C is varied directly and periodically by a surface wave flowing through the charge carriers (plate, housing, winding). The capacitor is fixed into an electrically oscillating circuit, which generates an electric oscillation by regulating the period thereof appropriately. The electric oscillation can be fed additionally as an AC current. Alternatively, electrical energy is fed to cause a designated oscillation thus generating a surface wave of a liquid.

Filed: 1988-05-19
Abstract: PURPOSE:To reduce a trouble with the cost decreased simplifying a device using a single cylinder pump by performing electric discharge machining turning on a machining power source only while the cylinder pump supplies machining fluid and turning off the power source while the cylinder pump supplies no machining fluid. CONSTITUTION:A dog 28 turns on a limit switch 29 with a piston 22 in its advancing limit, turning off a machining power source 31, solenoid valve 11 and 32 and turning on a pump 13, and an electric discharge is stopped by applying no voltage between a pipe-shaped electrode 1 and a workpiece. The pump 13 allows machining fluid to flow as shown by an arrow head C from a fluid tank 14 to be supplied to a chamber A, and releasing high pressure air in a chamber B from the solenoid valve 32, the piston 22 retracts. When the piston 22 retracts to the rearmost part, the dog 28 turns on a limit switch 30, turning on the machining power source 31 and the solenoid valves 11, 32 while turning off the pump 13, and the piston 22 advance being pressed by high pressure air supplied to the chamber B, allowing the machining fluid in the chamber A to flow out as shown by an arrow head D to be supplied to a point end part of the pipe-shaped electrode 1, thus performing an electric discharge in the point end of the electrode 1 with no flow toward the pump 13 because of a check valve 12.

At the comparator 2, through the prescribed slice level, the above-mentioned gradient-corrected picture signal is binary-coded and outputted from a terminal 53. In such a case, in the circuit 1, to respective types of the inputted picture signal, plural gradient-correctable nonlinear characteristics are suitably held, thereby, the effective gradiation correction can be executed for all originals, etc.

Title: Photo-detection device with built-in circuit
Inventor: NAGANO HIROKI
IPC: H01L31/10
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To output a regenerative signal with wide band and a servo signal at low offset voltage, by connecting p-n junctions, one consisted of an epitaxial layer of a first conductivity type and a diffusion layer of a second conductivity type, and the other consisted of a substrate and a buried diffusion layer of the first conductivity type, to another circuit as a photo-detector. SOLUTION: A p<+> buried diffusion layer 23 is formed by forming an n<+> buried diffusion layer 20 by dividing it on a P<-> substrate 19. A p<+> diffusion layer 22 is formed by forming an n<-> epitaxial layer 21 on the p<+> buried diffusion layer 23. Servo-detecting photodetectors 28a and 28b are arranged in track direction on both sides of the p<+> diffusion layer 22. Because a regenerative signal 29a needs be high speed, it is connected to a dedicated circuit and a signal is obtained at high speed without using a summing amplifier. A focus servo signal 29b is connected to a circuit which restrains the offset lower than for the photodiode. Thereby, a wide-band regenerative signal can be transmitted and a servo control can be performed at high precision.

Title: Semiconductor ic device

IPC: H01L21/331
Filed: 1979-09-28
Abstract: PURPOSE:To prevent the generation of SCR and the damage of device by preparing the maximum potential region between the I<2>L element and the saturated element on one semiconductor substrate. CONSTITUTION:An n<-> epitaxial layer is prepared through an n<+> buried layer on a p-substrate 1, on one island region separated by a p layer 4 an I2L device is formed, while on another island region a saturated element is formed. On an n<-> detached layer 12 between two p layers 4 an n<+> connecting layer 13 is prepared to make it into the maximum potential region connected with a power source Vcc and the p layers 4 are earthed. By such a constitution, although a parasitic pnp transistor is brought about between the saturated element p base and the p layers 4, this completely prevents the SCR formation. Consequently the coexistence of the IC device having the I<2>L element together with the saturated element does not cause the device destruction.

Title: Electronic thermometer

IPC: G01K13/00
Filed: 1984-06-15
Abstract: PURPOSE:To attain highly reliable measurement by determining convergence after the continuous detection of a changing ratio less than a prescribed value by the prescribed number of times. CONSTITUTION:A temperature sensor 1 detects a temperature and stores the detected value in a memory means 2 in every sampling timing. A changing ratio deciding means 3 and a convergence deciding means 4 for a detected temperature are formed in a CPU 16. The means 3 compares a detecting temperature obtained in each sampling timing with that obtained n times ahead of the sampling timing to calculate its changing ratio DELTA. When te changing ratio DELTA less than a prescribed value alpha (a constant) is detectd continuously by the prescribed number m (m=5 e.g.) of times, the means 4 determines convergence and generates a buzzer tone or displays characters or the like on a display means 5. Since convergence is determined at the stabilization of the detecting temperature close to a bodily temperature without determining it instantaneously even if the detecting temperature is temporally stabilized, high reliability is obtained.

Abstract: PURPOSE:To timely disperse the sound generating energy and restrict the generation of whistles by cutting the back edge of blade so that a blade-circular arc on the main plate side is shorter than that on the sub-plate side. CONSTITUTION:In a centrifugal impeller 20, plural blades 23 are held between a main plate 21 and a sub-plate 22 of the same diameter. The back edge of the blade 23 is cut so that its edge line runs from the outside periphery of the sub-plate 22 to the inside peripheral side of the outside periphery of the main plats 21. Thus, a time-difference can be produced between the times at which the back edge 31 situated on the main plats 21 side and the back edge 32 situated on the sub-plate 22 side cross a tongue 29-section of the casing. As a result, the pressure fluctuation that occurs when the blade 23 crosses the tongue 29-section of the casing is dispersed timewise, the sound generating energy is also dispersed, and thus, the generation of whistles is restricted.
