Filed: 1983-04-06
Abstract: PURPOSE:To discriminate between snowfall and rainfall by providing a temperature sensing element to the center part of a snow receiver dispersing plural small bored holes and using a snow temperature detector and a snowfall/rainfall detector in combination. CONSTITUTION:The snow temperature detector (a) is formed by providing the temperature sensing element 3 to the center part of the snow receiver dispersing plural small holes 1 and the detection signal of the temperature sensing element 3 is inputted to an OR circuit 13 through a detecting circuit 14. The detection signal of the snowfall/rainfall detector (b) which detects rainfall is amplified by an amplifier 12 and inputted to the OR circuit 13. A relay circuit 15 is driven by the OR signal between those two inputs and a device 11 to be controlled 11 is controlled intermittently to put snow melting facilities in operation. The snow receiver 2 catches snow pieces and the temperature of the snow pieces is measured by the temperature sensing element 3, so the precision of the snowfall detection is improved.

Abstract: PURPOSE:To uniformize the S/N ratio elevating the scan line density by arranging (n) pieces of adjacent vibrators handling the transmitting and receiving operations in common to drive the vibrators shifting the position thereof alternately one by one at each frequency of scanning divided into one group containing (n) pieces thereof and the other as (a+1) pieces. CONSTITUTION:Elements a1-a5 are selected (n=5) with an electronic switch 5 based on a signal S2 of a control circuit 6 to irradiate an ultrasonic beam. The reflected echoes are received with the elements a1-a6. In the second operation, elements a2-a6 are selected with shifting by one and the reflected echoes are received with the elements a1-a6. In the third operation, the elements a2-a6 are selected and driven at the transmission and those a2-a7 done with shifting by one at the reception. Scanning is repeated sequentially.

Title: Dynamic balancing tester
Inventor: MITSUHARA MASAYUKI
IPC: G01M1/16
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To correct unbalance by stopping a motor when the number of the first pulses and the number of pulses in correspondence with the rotation of the motor agree and the number of the second pulses and the number of the pules in correspondence with the rotation of a body under test agree, and finding the measured unbalanced position accurately. SOLUTION: The correcting position of a motor rotor 1 is found based on the unbalance angle of the motor rotor 1, which is detected during the rotation driven by a motor 2. A pulse generator 6 outputs the pulses in proportion to the rotation of the motor 2. A proximity switch 5 outputs the pulses in correspondence with the number of the poles of the motor rotor 1. The unbalance angle of the motor rotor 1 is converted into the first pulse number in correspondence with the pulse generator 6 and the second pulse number in correspondence with the number of the poles. When the pulse generator 6 outputs the first pulse number, the first coincidence signal is outputted. When the proximity switch 5 outputs the second pulse number, the second coincidence signal is outputted. The motor 2 is stopped by the AND of the first and second coincidence signals, and the position is found.

Title: Liquid crystal display panel
Inventor: HAMANAKA MITSUYOSHI
IPC: G02F1/1335
Filed: 1987-03-17
Abstract: PURPOSE:To permit display of black and good contrast without changing the hue and brightness when no electric fields are applied to a panel from the hue and brightness of the conventional panel by providing a filter for cutting a short wavelength side region on a polarizing plate. CONSTITUTION:This panel has the characteristic to cut a low band region. There is a problem of crosstalk and in addition, yellowish colors are visible and contrast is poor with a liquid crystal panel for which a filter 5 is used. Such panel is unusable. However, there is not transmission of 400-500nm wavelength and bluish colors are invisible when an intermediate electric field is applied to the panel. The bluish colors are thereby eliminated when the electric field in the actual use state is applied to the panel. The display of the black and good contrast is thus permitted.
