Title: Servo system
Inventor: TSUTSUMI SEISUKE
IPC: G05B19/19
Filed: 1992-10-27
Abstract: PURPOSE:To lighten the weight and reduce the cost of a servo system where a position detecting part having a detecting function of the revolving position of a servo motor is separated from a speed control part having a control func tion of the servo motor. CONSTITUTION:A connection cable 43 used for transmission of signals between a position detecting part 110 and a speed control part 114 is used for transmission of the electric power of a power failure back-up power supply 23 by the relays 106 and 107 in a power failure state. Meanwhile the signal transmitted from either one of both parts 110 and 114 is sent back to the other part. Then a fault of connection is decided by a fact whether the sent-back signal is coincident with the transmitted signal or not.

Title: Automatic meter inspection system
Inventor: NUKUI KAZUMITSU
IPC: G08C17/02
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To sense a carrier at short intervals exerting no influence on a communication time within the communication time by shortening the carrier sense intervals of a reception side under the control of a timer means and also shortening the transmit signal of a transmission side correspondingly. SOLUTION: In a communication state, a control means 3 actuates a power source control means 4 by set values of the set timer means 5 to supply electric power to radio equipment 2. The carrier sense function of the radio equipment 2 judges whether or not a radio wave is received by an antenna 1 in a short time. When no radio wave is received, the control means 3 stops supplying the electric power to the radio equipment 2 and when the radio wave is received, the power supply is maintained. For transmission, on the other hand, a link connection signal is sent from the antenna 1 in response to the start of the power supply to the radio equipment 2 from a standby state. The timer means 5 actuates a power source control means 4 to supply the electric power to the radio equipment 2.

This signal is analyzed by an analyzing circuit 13-2 in the master station and the difference (DELTAt) between the transmission time and reception time is calculated. The mean value of the difference DELTAt is found and the value which is a half as large as the means value is regarded as a transmission delay time T1. The data output timing of the master station is a time (T) delayed behind the absolute time previously by an output control circuit 13-3 and the time when the master station outputs data received from the slave station is set to T-T1, thus correcting the delay time.

IPC: G06T15/80
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a shading method for computer graphics which can generate the shade of an object in a short time with a small calculation quantity. SOLUTION: Light-beam information, viewpoint information, and information showing the shape of an object are inputted (S10). A temporary polygon in a shape circumscribed with the object is assumed at the position of the object while crossing a light source direction at right angles (S14). Then a shade polygon as a projection of the temporary polygon on a shading surface is found (S16) and shade texture is pasted to the shade polygon (S20). The shade texture is texture obtained by shading the texture of the object. The pasting is performed after the shade texture is adjusted to a shape matching the shade polygon according to the ratio of the temporary polygon and shade polygon. This method only finds the shade as to the temporary polygon, so the data process quantity of shading is small.

Several pores having about 0.2mm diameter are formed at about 1mm intervals in the outer surface of the bellows type container, and therefore, water and ions H<+>, OH<-> may be easily diffused into the high polymer gel 2. When a 0.05N of hydrochloric acid solution 3 and a 0.05N of sodium hydroxide solution 3 are alternately introduced into an outer container 6 made of SBR and is then discharged from an outlet port 5, the mechanochemical resin expands and retracts. Thus, it is possible to use the Volumeric change of insoluble high-polymer, effectively as the longitudinal expansion and retraction of the mechanochemical element.
