Filed: 1987-12-21
Abstract: PURPOSE: To facilitate the layout and its change of an operator terminal and a cache terminal and to increase the number of degrees of freedom of the layout by transmitting data from the operator terminal to the cache terminal in a radio system. CONSTITUTION: Data is transmitted between an operator terminal 1 and a cache terminal 2 by radio. Since there is not a signal cable, the layout of terminals 1 and 2 can be freely determined if data can be surely transmitted and received. The equipment construction of the signal cable is unnecessary, and it is unnecessary even at the time of changing the layout determined once. Thus, the layout of the operator terminal 1 and the cache terminal 2 and its change are facilitated, and the number of degrees of freedom of the layout is increased.

Title: Torque motor
Inventor: KONDO JIRO
IPC: H02P29/00
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a torque motor for obtaining smooth torque characteristics, without generating torque ripples. SOLUTION: If a current is attempted to be controlled to develop a nearly constant torque within the specific rotary angle range of a rotors as shown by a required torque 82, without considering the ripple of magnetic force when the torque is developed by energizing a solenoid part, the actually torque becomes the sum of the required torque 82 and a torque 81 when no energization is made as shown by a torque 83 before correction, thus torque ripples are generated and hence a correction current 84 is conducted with ripples whose phase deviates from that of the ripple of the torque 83 prior to correction by θA/2, preventing the torque ripple from occurring, and developing a torque that is nearly equal to the required torque.

Title: Generating method for void character
Inventor: FUJII KATSUYASU
IPC: G09G5/24
Filed: 1988-12-21
Abstract: PURPOSE:To generate the beautiful void character whose peripheral edge part is closed in a bag shape by increasing the width of a character by expanding the dot pattern of the character which is reduced in size and voiding the character with the character which is reduced in size. CONSTITUTION:An expanded character storage part (RAM) 7a and a size- reduced character storage part (RAM) 7b which are necessary for a void character generating process are connected to a void character modification part 6 which reads the font of a standard character out of a character generator 1c and generates a void character of the character. When the read character data is present at the upper or lower end of a dot display space, the character data is deleted from the end part to generate a size-reduced character which does not touch the upper and lower end part of a dot display space. The size- reduced character is expanded and then the character is larger in width than the size-reduced character in both upper and lower end directions in the dot display space. Then the expanded character is voided with the size-reduced character. Consequently, the peripheral edge part of the expanded character forms the void character in the closed bag shape.

Title: Liquid crystal display
Inventor: YOSHIDA HIDESHI
IPC: G02F1/1335
Filed: 1989-12-15
Abstract: PURPOSE:To accelerate the response speed of liquid crystal and to expand a visual field angle by setting the retardation of two sheets of liquid crystal panels at the same level or almost the same level and providing a matrix electrode at the liquid crystal panel on one side. CONSTITUTION:When the liquid crystal panel 10 on which liquid crystal molecules 75 are oriented vertically is laminated on the liquid crystal panel 12 on which liquid crystal molecules 55 are oriented horizontally, and light l1 vertical to the liquid crystal panel 12 enters, the liquid crystal of the panel 12 functions as double refraction for the light l1 and no liquid crystal of the panel 10 functions. Meanwhile, when light l2 having a certain angle (phi) is made incident on the liquid crystal panel 12, the function of double refraction for the light l2 by the liquid crystal of the panel 12 is decreased by the angle (phi), and the function of double refraction by the light l2 by the liquid crystal of the panel 10 is increased by the angle (phi). Therefore, when the light enters obliquely, the decrement of the function of double refraction of the panel 12 is offset by the increment of the function of double refraction by the panel 10. In such a way, the function of the liquid crystal for the light remains unchanged even when the visual field angle is increased, and the characteristic of the visual field angle can be improved.

Title: Learning method of learning value for judging knock of internal combustion engine
Inventor: ASANO MORIHITO
IPC: F02P5/152
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To improve learning accuracy by detecting whether a knocking signal is fluctuated or not at the time of learning of a signal level in which a knock signal is not superposed in ion current, solving fluctuation by lagging a phase of an ignition timing when fluctuation is detected, and learning the signal level in a condition in which the knock signal is nearly stabilized. SOLUTION: In the case where a learning value for judging knock is leant, in an electronic control device 6, an A/D converting value of a knock signal from ion current detected by an ion current measuring circuit 25 is set as a signal level NIONKNK. A coefficient is multiplied by a learning value memorized in a learning zone, and it is judged where the knock signal is a signal level which is not superposed or not. In the case where a learning condition is not setup, it is judged whether the knock signal is fluctuated or not. In the case where fluctuation is generated, a phase of an ignition timing is lagged, ignition phase lag control is repeated until the fluctuation of the knock signal is below a prescribed fluctuating ratio. After that, a back ground level is learnt, and a phase is advanced to an ignition timing of a normal operating condition.

Title: Formation of resist pattern
Inventor: SASAKI HIDEYUKI
IPC: H01L21/027
Filed: 1989-12-14
Abstract: PURPOSE:To form a fine resist pattern with high resolution and high sensitivity by performing cooling treatment wherein the vicinity of glass transition temperature of a soluble part is rapidly cooled after an exposed resist layer is annealed at a temperature immediately below glass transition temperature of a non- soluble part. CONSTITUTION:After an exposed resist layer is annealed at a temperature immediately below a glass transfer temperature of a non-soluble part (Tg1), cooling treatment wherein the vicinity of a glass transfer temperature of a soluble part (Tg2 where Tg2 < Tg1) is rapidly cooled is performed subsequently. In this case, by rapidly cooling the vicinity of Tg2 of the soluble part at the time of cooling the resist layer, contrast between the soluble part and the non- soluble part at the time of processing is improved so that sensitivity of the resist layer can be improved. Further by annealing non-uniformity in solution speed generated in an unexposed part around an exposed part at a temperature immediately below Tg1, 'cutting' at a border between the exposed part and the unexposed part is good to improve resolution. Thus a fine resist pattern can be formed with high resolution and high sensitivity.
