Title: Discriminating method for characteristic abnormality and automatic inspection instrument for taxiway of unmanned vehicle
Inventor: MIURA TOKUNORI
IPC: G05D1/02
Filed: 1986-10-23
Abstract: PURPOSE:To easily and surely discriminate the abnormality of a taxiway, by detecting derivatives at plural points having equal intervals in a direction orthogonal to the taxiway, and judging the characteristics abnormality of the taxiway based on discrepancy between the number of points where the output of a detecting element becomes larger than a reference value, and a reference number. CONSTITUTION:The output Vp of a pickup coil is proportional to a magnetic field (component in the axial direction of a coil) existing in a space where the pickup coil is placed, and the output Vp out of pickup coils in a sensor array 3 goes to Vp>=Vref (Vref: a reference value), however, 4-5 of them are counted. Meanwhile, when the buried depth (d) of an induction cable is changed locally by a cause such as secular change, etc., the distribution of a magnetic field at the position of the sensor array 3 is changed, and the number of the pickup coils having the outputs to satisfy the above equation is changed. Therefore, by monitoring the number of the pickup coils having the outputs to satisfy the equation, it is possible to detect the abnormality of the performance of the taxiway.

Title: Frying under reduced pressure
Inventor: OHASHI KAZUO
IPC: A23L19/00
Filed: 1985-11-12
Abstract: PURPOSE:To prevent the block formation of materials to be dried in a basket, by dipping a frying basket in oil to protrude the top thereof above the oil surface and frying the materials to be dried while stirring the materials to be dried. CONSTITUTION:Materials to be dried are filled in a frying basket 5 through which oil 2 is flowable and the frying basket 5 is then dipped in the oil 2 in a frying bath 1 to fry the materials to be dried with the oil 2 under reduced pressure.

Title: Liquid crystal display element
Inventor: OSADA HIROYUKI
IPC: G09G3/36
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To eliminate 'step response' by varying an impressed voltage so as to converge on a rather large voltage at the beginning of write-in and on a voltage close to a desired value at the end, and thereby obtaining a highly contrasted stable display. SOLUTION: A liquid crystal display element is equipped with an active element and employs as the liquid crystal material a chiral smetic C phase or its secondary layer liquid crystal. Then, a signal voltage and a common voltage are varied so that at the start of write-in time, a voltage is applied higher than the one corresponding to a desired light transmitting quantity in an impressed voltage-light transmittance curve, and that at the end of the write-in time, a voltage is applied close to the one corresponding to a desired light transmitting quantity. In other words, in 2/3 of the write-in time, the light transmittance state reaches only up to the curve (c); however, so long as writing is by a rather large voltage, the light transmittance state ultimately reaches a value close to the desired state.  Such driving eliminates excessive writing in which the saturation part of the curve (a) is reached, so that increase in writing quantity can be contrived effectively.

When the paper sheet is inserted into a reversal guide 19, the driving source is reversed, and the paper sheet is returned from the guide 19, and reaches a resistor roller 8 through a both surface transport part 21. When restart is performed, the both surface device 2 is switched to the original speed.

Title: Method and circuit for driving capacitive load
Inventor: KONOUE AKIHIKO
IPC: G09G3/288
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to drive capacitive load with low electric power and also optionally control the width of pulse applied to the respective capacitive loads. SOLUTION: When a capacitive load 13a is at a low level, a switch 16a is turned on and a switch 1 is turned on to supply a charging current from a power source 7 through an inductance element 5, but the voltage across the inductance element 13a rises with the resonance waveform between the inductance element 5 and capacitive load 13a to turn on a hold switch 9, so that a high voltage VH is held. When a hold switch 9 turns off, a switch 17a turns on, and a switch 2 turns on, a discharging current flows from the capacitive load 13a through the inductance element 6 and the electric power is collected to the power source 7, so that the voltage across the capacitive load 13a rises at thin time with the resonance waveform between the inductance element 6 and capacitive load 13a. Consequently, a high-voltage pulse with variable pulse width can be applied to the capacitive load 13a.
