Title: Driving method of liquid-crystal element
Inventor: OKADA SHINJIROU
IPC: G02F1/1368
Filed: 1984-06-11
Abstract: PURPOSE:To form an image on a large secreen at a high speed by connecting ferroelectric liquid crystal and FETs to intersections of an active matrix, and outputting a display signal obtained by impressing an electric field between a scanning electrode and a common electrode to a display electrode. CONSTITUTION:Glass substrate 1 and 1' are coated with a transparent electrode and liquid crystal of chiral smectic C phase having a liquid-crystal molecule phase 2 oriented at right angles to glass surfaces is charged between the transparent electrodes. When a voltage higher than a threshold value is impressed between the substrates 1 and 1', the spiral structure of liquid-crystal molecules 3 is destroyed and bipolar moment 4 is made uniform in an upward direction E or downward direction E' according to the polarity of voltage. This ferroelectric liquid crystal is connected to scanning electrodes 6 (CN, CN+1, and CN+2) of the active matrix M which consist of a scanning electrode 6 and a display electrode 7 and common electrodes 8 (SN, SN+1, and SN+2) through FETs, and outputs are sent from gates of FETs to display electrodes 7 (GN, GN+1, and GN+2). Consequently, an image is formed and displayed on a large screen at a high speed.

Title: Picture signal generator
Inventor: TAKAHASHI NOBORU
IPC: H04N17/04
Filed: 1987-05-15
Abstract: PURPOSE:To enlarge and observe the waveform of an arbitrary position on an arbitrary line on a screen by simultaneously outputting a trigger signal for arbitrarily setting a generating timing as well as a picture signal. CONSTITUTION:The generating timing of the vertical synchronizing signal of the picture signal (a) outputted from a picture signal generating circuit 21 coincides with the generating timing of the reference trigger signal (b) outputted from a control part 23. A delay time between the generating timing of the vertical synchronizing signal of the picture signal (a) and the generating timing of the trigger signals c, f externally outputted from a trigger signal generating circuit 25 is set in an operating part 22 through the control part 23. Thus, the generating timing of the trigger signals c, f externally outputted from the trigger signal generating circuit 25 can be set to an arbitrary position in the picture signal (a) of one frame. Thereby, the signal waveform of the arbitrary position on the arbitrary line on the screen such as a television can be simply enlarged and observed.

Title: Automatic clutch
Inventor: IRIE TSUNEO
IPC: F16H3/74
Filed: 1990-05-08
Abstract: PURPOSE:To simplify a mechanism by connecting a power input shaft to an output shaft via one of side gears of a differential gear, and fixing a brake disk controlled by an oil pressure to the other side gear so as to obtain an automatic clutch. CONSTITUTION:A power input shaft 1 is fixed to a drive pinion gear 9 having a ring gear 13. A side gear 10 is secured to an output shaft 3. Another side gear 11 is attached to a brake disk 8 having a hydraulic cylinder system 4. Since an oil pressure cannot be generated by a hydraulic control system 5 during low power rotation, the side gear 11 and the brake disk 8 are idly rotated, and the output shaft 3 is not rotated with application of a load. During middle power rotation, an increase in oil pressure reduces the rotation of the side gear 11. The rotation of the side gear 10 is increased by an amount of reduced rotation of the side gear 11 so that the power is transmitted to the output shaft 3. Combination of a differential gear and a hydraulic brake can realize a simple automatic clutch.
