Title: Ferroelectric liquid crystal element and driving method thereof
Inventor: TANIGUCHI OSAMU
IPC: G09G3/36
Filed: 1989-04-24
Abstract: PURPOSE:To increase a speed and driving margin and to improve driving characteristics by providing a compensation phase on a scanning signal waveform. CONSTITUTION:An information signal is constituted of the plural pulses consisting of a control phase part and an auxiliary phase part and the scanning signal has the pulse of the phase which compensates the pulse of the auxiliary phase part of the information signal. Namely, the auxiliary phase part of the information signal decreases the flickering, etc., of images but the scanning signal has the pulse of the phase to compensate the pulse of this auxiliary phase part and, therefore, the auxiliary phase part of the information signal is compensated. The driving margin is greatly improved in this way and the allowance to increase the frame frequency is generated, by which the increase of both the driving margin and the frame frequency is attained.

Title: Heat sensitive recording head
Inventor: HAMADA TSUTOMU
IPC: B41J2/335
Filed: 1990-04-18
Abstract: PURPOSE:To make it possible to set installation intervals between a electrodes to be extremely narrow by applying an electrode hairline around the conductor core of which is covered an insulating layer, as an electrode to add current to a resistant heating element. CONSTITUTION:For an electrode hairline 10, the periphery of a conductor core 30 made of various types of conductor metals such as copper, aluminum or gold, etc. is covered by an insulating layer 40 of polyurethane or polyimide, etc., and in addition, an external conductor 20 is formed on the outer periphery of this insulating layer 40 by solder-plating, etc. When voltage is added between the conductor core 30 of an optional electrode hairline 10 and the external conductor 20, current flows from the conductor core 30 to the external conductor 20 through a resistant heating element 50 as shown by arrow, and at this time, the resistant heating element 50 is locally heated by Joule heat. For the expansion of current, a possibility of the expansion to be wider than the outer diameter D of the external conductor 20 is extremely small, and therefore, there is hardly any possibility of the expansion of the generating area for Joule heat to exceed the outer diameter D. For this reason, when considering the outer diameter D as a recording area (recording dot), only the required area of the resistant heating element 50 can be efficiently heated.

Title: Speed controller for industrial machine including hoisting device
Inventor: NONAKA TERUO
IPC: H02P27/06
Filed: 1990-04-18
Abstract: PURPOSE:To accurately control a speed by driving a hoisting motor of a thrust brake by the output voltage of an inverter which outputs a driving voltage having a frequency responsive to a difference between a speed command value and a speed detected value, and controlling the speed of a main motor. CONSTITUTION:A voltage VD of a frequency responsive to a difference between a speed command value Vp and a speed detected value Vd is outputted from an inverter 46, and a hoisting motor 28 of a thrust motor is driven. That is, when the speed of the motor 16 is faster than the value Vp, the output frequency of the inverter 46 is reduced, the motor 28 is decelerated, and hence the hoisting force is reduced to increase a brake torque, thereby decelerating a main motor 16. On the contrary, when the speed of the motor 16 is slower than the value Vp, the output frequency of the inverter 46 is increased, the motor 28 is accelerated to increase the hoisting force, thereby reducing the brake torque to accelerate the motor 16. Thus, the set speed can be accurately controlled.

Title: Trimming scanner
Inventor: AZUMA YOSHIHIKO
IPC: G03F1/00
Filed: 1983-06-11
Abstract: PURPOSE:To obtain directly trimmed original image data by calculating variable power data from coordinate position data on two specific points on an original picture surface set on a read scanning surface and coordinate position data on two points which correspond to the two specific points of the original picture on an allocation base paper surface. CONSTITUTION:A trimming part is denoted as FT and trimming size is represented as dx and dy. When a controller 16 detects a reference point P1' by scanning original picture F, a pulse having width equal to the time Tdy required to move a scanning point by distance dy from the detection time t0 is generated at every scanning line period L to obtain a gate signal GT, and the generation of this pulse is repeated for a time equal to the time Tdx when the scanning point moves from a reference point PT in an X direction by the distance dx. Consequently, a gate 17 turns on every time the pulse of the gate signal GT appears to pass a picture signal SS, and a triming picture signal ST obtained by extracting some of said picture signals at specific timing is outputted, so that an unexposed film on a scanning drum 2 is exposed directly to a trimmed picture.
