Title: Level detection circuit
Inventor: UNO TAKASHI
IPC: H01L21/66
Filed: 1987-04-13
Abstract: PURPOSE:To eliminate the danger of a false operation, by setting a level shift circuit element so that the potential of a high impedance output node of a voltage generating circuit output is not changed by capacity coupling. CONSTITUTION:An output 011 of a voltage generating circuit is inputted to the gate of an N-channel MOS transistor M13, while an activation signal A is inputted to the gate of a P-channel MOS transistor M14. Although the output 011 is of high impedance, the potential V11 of the output 011 is not raised by the gate-source capacitance of the transistor M13, because the source potential of the transistor M13 can only be lowered when the transistor 14 starts to be in continuity. Accordingly, the potential V12 of an output node 012 of a level shift circuit shows no rise either due to a false operation. The danger of the false operation can be eliminated by this constitution.

Abstract: PURPOSE: To improve the positioning precision of a whetstone table, etc., with a simple constitution by covering a range exceeding the precision of a positioning detector by using a pulse signal from an encoder with resolution several times as high as it.  
     CONSTITUTION: Magnet scale 2 fixed to a table (not shown in the table) outputs single pulse Ps on every movement of the table of 1μm, and encoder 3 connected direct to the shaft of motor 1 converts it into a table-movement value and ouputs one pulse Pe at each 1/8μm. Motor 1 is driven by a voltage varying in stages via D/A converters 5 and 8 at every arrival of one pulse, pulse Ps with position deviation ΔP greater 1μm, pulses Ps and Pe with ΔP less than 1μm, or pulse Pe with ΔP equal to 0μm, and it stops at a voltage of OV. Since the resolution of encoder 3 is 1/8μm, the control within a range of ±0.25μm away from the table stop position is possible.

Filed: 1994-04-28
Abstract: PURPOSE:To obtain the guide cart which can travel safely even on an uphill slope and a downhill slope by providing a main controller which places an acceleration motor in operation in the direction wherein the main body starts and releasing main brakes. CONSTITUTION:Once a travel start signal is received from a remote control transmitter 45, the engine is actuated and start operation is entered. When the engine 20 is started, a tilt sensor 67 detects how much the main body 1 at a stop slants; when the angle is >=5 deg., a main controller 48 judges an uphill slope and a brake motor 36 operates with 50% of the power to place drum brakes 60 in operation. Once a start command is inputted, parking brakes 65 are released and then while the acceleration motor 57 operates in the direction wherein the main body 1 starts, the drum brakes 60 are released. Therefore, while the main body is in a stop state, the main body are braked by the two brakes and when the start operation is entered, the driving force increases while the drum brakes 60 are released, so the main body can start safely without moving back on an uphill.

Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a puffer type gas circuit breaker having stable arc- extinguishing performance and high reliability, by adjusting the amount of arc-extinguishing gas blown against the end of an arc contact. SOLUTION: In this puffer type gas circuit breaker, a sub-puffer chamber 22 is formed in a fixed arc contact 2A, a sub-puffer piston 21 interlocking with a movable electrode part 4 is provided in the sub-puffer chamber 22, and a blowout hole 23 for arc-extinguishing gas is provided in an end part of the fixed arc contact 2A. At interruption, when the movable electrode part 4 moves, the sub-puffer piston 21 in the fixed arc contact 2A moves together thereby causing the arc-extinguishing gas to jet out from the blowout hole 23 provided in the end part of the fixed arc contact 2A. In the late stage of interrupting action when the amount of gas blown out from an insulating nozzle decreases, a necessary amount of gas for arc extinction is blown against a concentrated electric field part on the end part of the fixed arc contact 2A, thereby stabilizing the interrupting action.

IPC: B41F33/14
Filed: 1984-05-08
Abstract: PURPOSE:To make it possible to perform smooth multi-color printing, by controlling the braking force to a roll to bring such effect that proper braking force is imparted to a printing belt to absorb a running speed error caused by the error from the aspect of printing accuracy generated between a plate cylinder and the sprockets secured to both sides said plate cylinder and other various factors. CONSTITUTION:The rotary speed V1 of a plate cylinder 10 is made synchronous to the inherent running speed of a web 32 to be printed but the running speed V3 of a printing belt 18 is apt to become faster than the reference speed V2 of feed teeth 38 at the point P being the center part in the thickness of a film (V3>V2). Because of this, the feed teeth 38 of a sprocket 34 has a tendency riding on or approaching the delay side of the feed perforations of the printing belt 18. At this time, the braking force of a brake means is controlled to impart proper braking force to a tension roll 14. The peripheral speed V4 of the tension roll 14 is set so as to become smaller than the rotary peripheral speed V3 of the printing belt 18 (V4<V3). That is, force in the direction braking the printing belt 18 is acted on the printing belt 18.
