Title: Pulse width modulation type inverter apparatus
Inventor: ITO TOMOTAKA
IPC: H02M7/48
Filed: 1989-08-23
Abstract: PURPOSE:To reduce noise of a motor and to suppress a loss by controlling a carrier frequency in cooperation with an output frequency of an inverter or temperature, load current of a controllable element. CONSTITUTION:An essential section is composed of a DC power source 100, an inverter 200, a motor 300, a reference voltage generator 400, a carrier generator 500, a PWM circuit 600, a driver 700, a temperature detector 800, an output frequency setter 900, etc. The generator 500 determines a carrier frequency in cooperation with temperature of a controllable element of the inverter, the output frequency or output current of the inverter. When a detected temperature or rotating speed of a motor is low or an output is small, the carrier frequency is raised to suppress generating noise. When the detected temperature is raised and the output current becomes large, the carrier frequency is reduced. Thus, noise, loss can be suppressed to low values.

Title: Latching relay
Inventor: TANAKA YOSHIO
IPC: H03K17/60
Filed: 1985-09-30
Abstract: PURPOSE:To reduce the drive power and to increase the stabilizing function of an output voltage by providing a power transistor (TR) turning on/off a power line, a current pulse transformer using a saturable reactor and an error amplifier keeping the on-state of the power TR so as to turn on/off the power line. CONSTITUTION:In closing a switch S11 to apply a voltage EON to the ternary winding N3 of a current pulse transformer T1 in order to turn on the power TR Q11, an on-pulse current ION flows to the winding N3 through the path comprising a capacitor C13, a resistor R13 and the winding N3. When the current ION flows to the winding N3, a current flows to a winding N1 and the TR Q11 is driven via a reverse-flow preventing diode CR15 by an error amplifier U1 before the transformer T1 is saturated to keep the on-state of the TR Q11. Then a switch S12 is closed to apply a voltage EOFF to the 4th winding N4 of the transformer T1 thereby turning off the power TR Q11.

Title: Pinch valve device
Inventor: KAWAI YOSHIO
IPC: F16K7/06
Filed: 1982-12-10
Abstract: PURPOSE:To reduce as small as possible the volumetric change in a path at one side of a closed pipe by displacing a pair of pinching portions in the other longitudinal direction of the elastic pipe. CONSTITUTION:In a pinch valve device 18, when a lever member 66 is rotatably displaced in the direction L, a roller 56 is displaced in the direction N and a roller 57 in the direction P. Both rollers approach each other while displacing vertically upward so that an elastic pipe 53 is pinched by side walls to be flattened. When the lever member 66 is further pivotally displaced in the direction L, a path 69 is completely closed. In this closure, a portion of a pinched portion 68 which is subjected to the largest compressive deformation due to the rollers 56, 57 is moved somewhat upward by the upward movement of the rollers 56, 57. Thus, the reduction of volume of an underside path 71 can be compensated by the volume increase of the path 71 due to the upward movement of the pinched portion 68 accompanying the upward movement of the rollers 56, 57 so that the volumetric change in the underside path 71 can be kept as small as possible until the path 69 is completely sealed after the closure.

Title: Method for driving liquid crystal display device
Inventor: NOMURA TAKAO
IPC: G02F1/133
Filed: 1993-08-31
Abstract: PURPOSE:To provide a method for driving a liquid crystal display device capable of obtaining an excellent display by sufficiently increasing the voltage applied to a liquid crystal layer without prolonging a selection period and enlarging a current limit value Izmax. CONSTITUTION:The voltage Vin applied to both ends of a series circuit constituted of the liquid crystal layer and a non-linear resistance terminals element is varied from the immediately after time Vss starting the selection period to the immediately before time Vse ending the selection period, and the change of the voltage Vz applied to the non-linear resistance two terminals element in the selection period is made smaller. Thus, when the current limit value Izmax of the non-linear resistance two terminals element is equal to that of using a rectangular wave pulse, a liquid crystal layer applying charge is made larger compared with the case when the rectangular wave pulse voltage is used.

Filed: 1990-08-17
Abstract: PURPOSE: To provide a mortar, which can be abolished healthfully for environments by mixing an anhydrite binder, sand, fluidized bed ash, water and specified additives.  
     CONSTITUTION: This mortar is made of mixture composed of the anhydrite binder, sand, fluidized bed ash created by burning a sulfur-bearing fuel in a fluidized bed, water and one additive at least selected out of a liquefying agent, dispersing agent, stabilizer and defoaming agent. The fluidized bed ash to be used is provided from burning facilities, and its composition depends on the character of a fuel to be burnted in the burning facilities. When using the fluidized bed ash created by burning the coal of comparatively more sulfur content such as containing sulfur in 3%, for example, the ratio of fluidized ash in the mortar can be increased rather than the case of using the fluidized bed created by burning the fuel containing comparatively a little sulfur. The floor made of this mortar is improved especially in distortion tensile strength and a swelling number.
