Title: Driving method for liquid crystal matrix panel
Inventor: WAKITA HISAHIDE
IPC: G02F1/133
Filed: 1986-11-26
Abstract: PURPOSE:To realize high contrast display without degrading a liquid crystal by applying a DC component to most of a scanning period, and applying a pulse, which neutralizes the DC component, just before or a little before a selection period. CONSTITUTION:A ferroelectric liquid crystal 4 is held between a pair of substrates 1 whose counter faces electrodes are provided on to form matrix picture elements, and an asymmetrical memory is provided. In this case, the DC component is applied in most of the scanning period, and the pulse which neutralizes said DC component is applied just before or a little before the selection period. Only a scanning voltage is set to a prescribed waveform at the time of selecting another scanning electrode to apply said neutralizing pulse to a panel. Thus, the liquid crystal is prevented from being degraded by electrochemical reaction, and the panel having the asymmetrical memory is easily oriented as desired by the surface treatment like rubbing.

Filed: 1988-11-09
Abstract: PURPOSE:To increase play effect by attenuating speedily a musical sound signal which is generated by a strike on a strike surface other than a specific strike surface when a strike on the specific strike surface is detected. CONSTITUTION:Sensors 1a - 1d are strike sensors provided on a strike surface (pad) and output analog signals corresponding to a strike force to the pad. Control circuits 2a - 2d are circuits which obtain envelope signals for prescribing an attenuation time from the analog signals outputted by the sensors 1a - 1d.

Title: Shift lever device
Inventor: NAGASHIMA KATSUSHI
IPC: F16H59/12
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a shift lever device capable of miniaturizing a knob of the shift lever and improving the operationability of the lever. SOLUTION: When a knob button 14 is pressed down, a piece 24 is moved so as to press a detent rod 28 down. At the same time, the piece 24 is rotated by an inclined guiding part 30, thereby further pressing down the detent rod 28. Thus, since the moving stroke of the knob button 14 to obtain a necessary stroke of the detent rod 28 can be shortened, the knob 20 can be miniaturized. Since the inclination of the piece 24 gradually approaches a right angle to the shaft line of the detent rod 28 as the knob button 14 is pressed down, the depressing force of the knob button 14 can be made smaller and the operability of the knob button 14 can be enhanced.

Abstract: PURPOSE:To prevent machining accuracy from lowering due to deformation of a lower arm by controlling such that the contraction/expansion rate of a shield body is always constant corresponding to the relative movement distance between a machining tub and the lower arm of a wire electric discharge machine. CONSTITUTION:A wire electric discharge machine is provided with a lower arm 5, a machining tub 18, a position detector 23 and a control means. Based on a positional information on a saddle 12 of the machining tub 8 obtained from the position detector 23, a servo system 22 causes a motor 21 to rotate and unwind a drive belt 20b from a drive bobbin 20d. Because a force in the winding direction is always exerted with a spring 20e on a winding bobbin 20c, a winding belt 20a is wound on the winding bobbin 20c by the elongated length of the drive belt 20b. This action takes place until a cut 19 on the shield body 18 reaches the position of the lower arm 5.

Title: Enclosed type alkali manganese secondary battery
Inventor: KONDO MASATSUGU
IPC: H01M4/50
Filed: 1985-12-16
Abstract: PURPOSE:To form such an enclosed type alkali manganese secondary battery that is excellent in a pressure proof characteristic and economical, by adding the specified quantity of silver oxide to manganese dioxide or a main positive active material. CONSTITUTION:In this battery, silver oxide is added to a 100pts.wt. of manganese dioxide or a main positive active material in a range between 5 and 20pts.wt. With the silver dioxide in this range added to the manganese dioxide or the main positive active material, an excellent charging characteristic of the silver oxide, among others, a pressure proof characteristic controls a battery system, and a galvanic voltage suddenly goes up to the extent of voltage for a pressure proof test, and a charging current flowing in the battery suddenly decreased. Therefore, the galvanic voltage gradually goes up to the extent of the voltage for the pressure proof test as a battery whose positive electrode is constituted of the manganese dioxide alone, and it is reached up to the pressure proof voltage for long hours, thus during this while, the charging current continues to flow in the battery. With this continuation, as a result, such a possibility that gas generation becomes much enough is brought to nothing, thus such an enclosed type alkali manganese secondary battery that is excellent in the pressure proof characteristic is produced.
