Title: Viscosity measuring apparatus for high temperature fluid
Inventor: MORITA ZENICHIROU
IPC: G01N11/16
Filed: 1982-07-16
Abstract: PURPOSE:To measure the viscosity of a fluid of a high temperature and low viscosity by providing a heat resistant and corrosion resistant vibrator at the tip of a vibration rod having a coil spring interposed while providing a vibration means and a displacement sensor at the other end thereof. CONSTITUTION:A coil spring 4b is interposed at the intermediate section of a vibration rod 4 while a platinum vibrator 5 of a heat and corrosion resistance is mounted at the tip thereof and a vibration coil 6 and a displacement sensor 7 are provided at the upper end thereof. As the vibrator 5 is vibrated through a coil 6 with a vibration control circuit 8, the vibration is attenuated depending on the viscosity resistance of the fluid 1. The amplitude value E is detected with a displacement sensor 6 and inputted into an arithmetic circuit 10, which calculates the ratio between the amplitude E and the amplitude Ea obtained when the vibrator 5 is vibrated in the air on the same condition and the viscosity of the fluid 1 is measured by a specified equation. Thus, the effect of the damping time characteristic is ignored to upgrade the accuracy significantly thereby enabling the measurement of the viscosity of a melted metal of a high temperature and a low viscosity or the like.

Abstract: PURPOSE: To reduce a delay time and its change after commanding the start and to cut material of a fixed length precisely by feeding current, which produces a torque less than the starting torque of the cutting machine drum, before the starting.

Here, the value of current reference signal 24 is made less than the frictional current of the cutting machine. By this way, the motor starts and turns by backlash with the shaft of drum 2, but the motor is stopped at the time because a torque required to turn the drum 2 is not produced, and it can respond quickly to the next starting.

Title: Stn type liquid crystal display device
Inventor: SUGIYAMA TAKASHI
IPC: G02F1/133
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To prevent leaking of light in a black display and to improve the contrast ratio and a black tone of a black display by controlling the reflectance of a thin film of a wavelength component shorter than the center wavelength in the wavelength range of transmitted light to be smaller than the reflectance in the longer wavelength region. SOLUTION: The film thickness of alignment films, transparent electrode films or overcoat thin films is set so that the reflectance of thin film of the wavelength component on the shorter wavelength side than the center wavelength of the wavelength region of the light transmitting a liquid crystal cell is controlled to be smaller than the reflectance of the longer wavelength component so as to control the reflected components of light on each interface in a liquid crystal cell. Practically, for example, the wavelength region ranges from 400 nm to 520 nm. The optimum film thickness of each thin film varies depending on the refractive index of the film, combination of films, refractive indices of substances except the thin film such as a glass and liquid crystal, or the like.  The reflectance of light in the shorter wavelength region is preferably decreased, because the period of changes in the transmittance with changes in the wavelength is shorter in the shorter wavelength region than the center wavelength of the spectrum of transmitted light, and because the max. transmittance in each peak in the shorter wavelength region is larger than that in longer wavelength region.

Filed: 1993-05-27
Abstract: PURPOSE:To suppress an abrupt change in the deviation of PID control and prevent control characteristics from becoming uneven by providing a deviation processing means which adjust the deviation with the switching signal and controlled variable of a control variable input switching means in front of a PID arithmetic means. CONSTITUTION:When the controlled variable PV1 from a 1st controlled variable input means 1a is switched to another controlled variable input means, e.g. 1b by the controlled variable input switching means 2, its controlled variable PV2 is inputted as a controlled variable 5 to the deviation processing means 3, but the switching signal 4 is outputted from the controlled variable input switching means 2 to the deviation processing means 3 at the same time and this means 3 is applied with the signal from a controlled variable setting means 6. Then the deviation processing means 3 determines the deviation from the switching signal 4 and controlled variable and outputs the deviation to the PID arithmetic means 7. In this case, the deviation processing means 3 substitutes the deviation of the controlled variable PV2 from a 2nd controlled variable input means 1b for the deviation of the controlled variable PV1 temporarily and then executes the controlled variable PV2.

Abstract: PURPOSE:To prevent the reduction of throughput, the rise of cost, or disturbance of a picture by providing V.RAMs for two pictures where display data is stored and automatically copying contents to one V.RAM synchronously with the read dependent on the display address of a display controller. CONSTITUTION:V.RAMs 2 and 3 for two pictures are provided, and the V.RAM accessed by a CPU 9 and the V.RAM accessed by a display controller 1 are separated, and a circuit is provided which uses the address for access of the display controller 1 to equalize contents of two V.RAMs 2 and 3.
