Title: Running control system of moving body
Inventor: KAWAGUCHI TOMOKI
IPC: G05D1/02
Filed: 1981-05-30
Abstract: PURPOSE:To precisely detect a distance over multiple points in a wide dynamic range by forming a running control signal of a detected optical pulse signal that is subjected to amplitude modulation at the max. light receiving sensitivity in a digital manner. CONSTITUTION:The current in a light emission diode D mounted on a preceding car is an intermittent pulse in a frequency F2 and a cycle t. Because the its amplitude value becomes smaller in order by resistances of R1<R2<R3, its sending light comes to a seris of intermittent lights of the first- the third waves smaller in amplitude in order. In the receiving circuit of a following car 2, when the distance between the cars is enough, the receiving output Es< reference voltage Er is satisfied, and the output Ec of a comparator is zero. If the distance is reduced, the first wave of the sending light exceeds the Er and a pulse is generated in the Ec. That it to say, the Ec corresponds to the distance between the cars. With generation of the pulse (a), a decoder 28 outputs to a sending terminal Q11, with detection of the third wave, to terminals Q11 and Q12, with detection of the third wave, outputs to all the terminals. With this process, a speed is controlled in correspondence to the distance between the cars.

Title: Video signal mixing processing method
IPC: H04N9/74
Filed: 1992-04-03
Abstract: PURPOSE:To substitute a picture without using a curtain of a specified color by providing a storage circuit before a differential circuit. CONSTITUTION:When being indicated by the control signal inputted from a control signal input 20, the first video signal inputted from a first video input 11 is inputted to a storage circuit 30 and is stored as a first picture signal. Meanwhile, the first video signal is inputted to a differential circuit 14, and the stored first picture signal is subtracted. The output signal of the differential circuit 14 is inputted to a discriminating circuit IS to output the discrimination result indicating whether the first video signal and the stored first picture signal are close to each other or not. A selecting circuit 16 selects the inputted first video signal or the input video signal inputted from a second video input 13 in accordance with the discrimination result and outputs the selected signal from a video output 17. Since a preliminarily taken-in background picture is used to substitute only the background area with another video or still picture without using a curtain or the like by this method, this method can be applied to the background picture processing in the visual telephone or the like.

Title: Battery performance recovery method of lithium secondary battery
Inventor: SUGIYAMA JUN
IPC: H01M10/052
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To effectively recover battery performance against continuous charge- discharge in a high-temperature environment, capacity degradation during storage and power degradation by keeping the battery in an overdischarge state of which overcharge voltage is in a specific range when the battery performance is degraded. SOLUTION: By bringing a battery of which battery performance is degraded into an overdischarge state, a film of a Li containing compound formed on the surface of a negative electrode is decomposed and Li in the film is dissolved in an electrolyte and returns to a positive electrode. Thereby, the positive and negative electrodes return to a state like that of a new product, so that the battery performance is recovered. The battery voltage in overdischarge is set to 1.2-2.5. When the voltage is too low, the film of the Li containing compound formed on the surface of the negative electrode is entirely decomposed, this situation is not desirable for the stabilization of charge and discharge, and metal ions are dissolved from a negative electrode collector so that the adhesion between the collector and a negative electrode material is degraded.  When the voltage is too high, the recovery performance of the battery tends to be degraded as well.

Filed: 1991-04-15
Abstract: PURPOSE:To eliminate a left and right contrast irregularity by correcting an effective value by making the nonselection time of a left picture element longer than that of a right picture element by a select pulse generating circuit and a signal electrode driving circuit. CONSTITUTION:A positive pulse is generated in synchronism with the rise of a latch pulse LP each time the latch pulse LP reaches a select signal EN. The select signal EN sent to the nonselection control terminal 1NH- of the driver 2a of a signal driving circuit 2 and when the nonselection control terminal 1NH- goes down to a low level, the output signal S1 of the driver 2a reaches a nonselection level. The output signal S1 of the driver 2a drives a picture element P1 close to a scanning electrode driving circuit 4. The nonselection control terminal 1NH- of a driver 2b, on the other hand, is connected to a high level, so display data DATA is outputted having pulse width matching the period of the latch pulse LP without being affected by the select signal EN. For the purpose, the pulse width of the select signal EN is so adjusted as to correspond to an operating voltage.

Abstract: PURPOSE:To lighten the molding concerned and improve its wear resistance by a method wherein polyurethane layer produced by adding aromatic diamine to urethane polymer, which is obtained through the reaction so that the molar ratio of isocyanate group to hydroxyl group exceeds the specified value, outside hollow body made of polymeric material. CONSTITUTION:The molding concerned is produced by covering the outside of polymeric material, which is lightened by containing gas by polyurethane prepared through the reaction between aromatic diamine and isocyanate group- containing urethane polymer prepared by polyol and polyisocyanate, which is in excess to said polyol. As the usage ratio of isocyanate group in polyisocyanate to hydroxyl group in polyol, the molar ratio of isocyanate group to hydroxyl group is 2 or more and preferably about 2-3.5. If said molar ratio is less than 2, polyol and isocyanate cause a chain reaction and product with large molecular weight results and no fluidity of the product results, resulting in causing trouble at the forming of the molding. The gas-containing hollow body is prepared by making a film-like hollow body out of polymeric material so as to receive gas in the interior of the hollow body.
