Abstract: PURPOSE:To rapidly and uniformly perform the effect of cooling a steel plate with the movement of cooling water, by attaching blades having a specified configuration to the rotary shaft of an impeller for agitating cooling water provided in a water tank for quenching the steel plate. CONSTITUTION:An impeller 132 for moving cooling water is used to carry the cooling water at a high speed along a direction opposite to the running direction of a steel plate inside a water tank for rapid cooling in an apparatus for quenching the steel plate. Four pieces of blades 140 are provided at the periphery of the rotary shaft 136 of the impeller along the longitudinal direction of the rotary shaft 136 in the same intervals along its radial direction. The blades 140 are helically attached to the rotary shft 136 in a manner such that the angle alpha of torsion of the blades to a hypothetical plane including the axis of the rotary shaft 136 is made below 30 deg. from he standpoint vertical to the axis. The steel plate is uniformly rapidly cooled with excellent cooling efficiency without the stagnation of cooling water heated at a high temperature around the rotary shaft of the impeller 132.

Title: Driving method for active matrix liquid crystal display device
Inventor: SUZUKI YORIHISA
IPC: H04N5/66
Filed: 1989-08-10
Abstract: PURPOSE:To display an ID-TV image without varying the driving frequency of a drain driving circuit by separating an ID-TV signal into odd-numbered horizontal lines and even-numbered horizontal lines, making them coincident in output timing and putting the frequency back to the original frequency, and performing doublespeed line sequential driving according to the signals of the odd-numbered and even-numbered horizontal lines. CONSTITUTION:The output signals of tri-state buffers 15a-15c are led out of a common output line DL and sent as a drain line driving signal Di to a liquid crystal display device. Here, an ID (Improved Definition)-TV signal which has a horizontal frequency twice as high as that of a video signal is separated into the odd-numbered and even-numbered horizontal lines and after they are made coincident in output timing, the conversion to the frequency of the original signal is performed, thereby performing the double-speed line sequential driving of the liquid crystal display device with the frequency-converted video signals of the odd-numbered and even-numbered horizontal lines. Consequently, the ID-TV signal can be driven without making the driving frequency of a drain driving circuit different from that in NTSC driving.

Title: Etching method for aluminum film
Inventor: HIROSE ZENKO
IPC: H01L21/302
Filed: 1985-09-20
Abstract: PURPOSE:To etch an Al film without damaging the element of an under layer by irradiating rays of specific wavelengths to a photodecomposable chlorine- contg. material and bringing the resulted product of photodecomposition into contact with the part intended to be etched of the Al film. CONSTITUTION:The rays of <=400nm wavelength are irradiated to the photodecomposable chlorine-contg. material to decompose at least part thereof. The chlorine in an active state which is the resulted product of the photodecomposition generated by such irradiation is brought into contact with the part intended to be etched of the Al film. The formed AlCl3 is thereby volatilized and the Al film is etched. Only the part irradiated with the light can be etched by making use of an increase in a reaction rate when the part of the Al irradiated with the light is increased in temp. or chemically activated. BCl3 is adequate as the above-mentioned photodecomposable chlorine-contg. material. ArF eximer laser light having >=1mJ/Shot/cm<2> energy at 126-400nm, more particularly 170-250nm wavelength is adequate for the above-mentioned rays. The pressure of the reaction system is adequately in a 1-2X10<5> Pa range.

Title: Molecular beam epitaxial device
Inventor: YAMASHITA TATSUYA
IPC: H01L21/203
Filed: 1985-09-18
Abstract: PURPOSE:To be capable of obtaining a large area of an epitaxial layer highly uniform in film thickness and composition ratio and effectively utilizing molecular beams, by arranging group III and dopant molecular beam sources having a doughnut-shaped opening part so that they surround the outside of group V molecular beam source. CONSTITUTION:Group III molecular beam sources 4 are composed of a doughnut-shaped opening part which is rotationally symmetrical to an axis 1 passing through both a center of a GaAs substrate and that of an arsenic molecular beam source 3, and arranged so that they surround the arsenic molecular beam source 3. Intensity F(r) of molecular beams radiated on a point P of the growth substrate 2, which is distant r from a center O of the substrate 2, is based on a Knudsen's theory. With several factors properly chosen, the group III and dopant molecular beam sources, e.g., plural doughnut-shaped molecular beam sources for gallium or the like, are arranged rotation- symmetrically with a center axis 1 of a group V molecular beam source 3 serving as a rotational axis. Thus, every molecular beam can be radiated uniformly on the growth substrate 2. Such composition enables a growth layer uniform in film thickness and composition ratio to be available as the growth substrate is fixed.

Title: Oil temperature detector of hydraulic elevator
Inventor: YOSHIIE HIDEO
IPC: G01K7/16
Filed: 1982-11-29
Abstract: PURPOSE:To allow only one sensing element to detect accurately oil temperature necessary for the control over a hydraulic elevator by detecting the oil temperature in an oil tank and judging whether the detected value is higher than a set value or not and whether the breaking of wire occurs or not, with only one sensing element. CONSTITUTION:The input signal voltage Vi to an A-D converter 10 is obtained by dividing the voltage of a DC power source 3 by the sensing element 2 and a resistance 8, so it is determined by the resistance value of the sensing element 2 corresponding to the temperature in the oil tank 1. The input signal voltage Vi is converted from analog to digital by the A-D converter 10 and outputted from a terminal V10. At this time, the digital signal operates on every resistance value that the sensing element 2 may has and optional oil temperature is detected. If the breaking of wire occurs to the element 2, the input signal Vi is ceased and the digital signal corresponding to that is outputted, so the breaking of wire is also detected. Therefore, a control circuit outputs the control command matching with the oil temperature on the basis of the digital signal to operate the elevator in safety.
