Granted: 1990-08-01
Abstract: The reference infrared ray source (5) is provided on the opeining side of the mirror (3) across a chopper (6) of a moving blade-type disc with notch portions (7) to constitute a kind of opeing or closing means. The chopper is adpated to apply the infrared rays onto the mirror only when the notch portions are located in front of the reference infrared ray source, and the chopper interrupts the reference infrared rays when the notch portions are not located in front of the reference infrared ray source. The chopper is rotated by means of a motor (M1) to shift the position of the notch portions before the reference infrared ray source. Whenther or not the notch portions are located in front of the reference infrared ray source is detected by the position detector (T1). The latter sends a signal to a mode discriminating device (14).

Granted: 1998-11-16
Abstract: A membrane gas separation apparatus, typically for separating air, includes a gas separation all 14 containing an array of membranes in the form of hollow fibres 18. The cell 14 has a first gas port 16 and a second gas port 20. Flow of gas to and from the ports 16 and 20 is controlled by a four-port, two-position valve 12. In one position, the valve 12 admits incoming air to the port 16 and allows product nitrogen to flow out of the port 20. In the other position the roles of the ports 16 and 20 are reversed and hence the direction of flow of the gas is reversed. During prolonged operation, there is a tendency for contaminants to affect disproportionately the feed gas inlet and of the membrane fibres 18. By periodically changing the position of the valve 12, different ends of the membrane fibres 18 are presented to the feed gas, and thus the operating life of the membranes 18 is lengthened. <IMAGE>

Abstract: calculating the rectilinear length by obtaining a current position and a target position on an X-Y plane; obtaining a movable distance to be transferred per sampling time when there is no speed change; obtaining the number of movements based on the transferred movable distance by using the rectilinear length when there is no speed change; processing the remainder produced in calculating the increased linear amount per sampling time by means of a discrete time state equation; calculating the increased amount on X and Y axes by using the increased amount of the straight line; calculating the pulses of respective joints by an inverse-kinematic method of the robot to calculate positional deviation based on the current position detected by operating target positions of respective joints at an optional point; and performing PID control and feed forward control to the positional deviation to output the result as a driving signal of a servo motor. The method thereby shortens sampling time and improving rectilinear accuracy while enabling high-speed movement of the robot.

Title: Apparatus of detection for fuel level
Inventor: LEE SUNG-JOO
IPC: G01F23/22
Filed: 1992-05-15
Granted: 1996-04-30
Abstract: The apparatus, detecting the level of the fuel in automobiles, boilers or industrial equipments, has a structure easy to assemble, prevents malfunction caused by the flow of the fuel, and reduces the consumption of the electric power. It comprises a level detector(10) including serially-connected NTC(negative temperature coefficient) thermisters(18) sensing the resistor variation according to the change of the fuel level; a heating plate case(15) having a guide groove(16) for the detector(10) to be fixedly inserted into; a constant temperature heater(11) regulating the temperature of the detector(10) in order not to be affected by the external temperature by use of a heating wire(13) and a constant temperature unit(14); a fule flow checker(12) preventing the wrong operation of the detector(10).

Title: Optical switch
Inventor: DORN REIMUND
IPC: G02F1/355
Filed: 1992-05-21
Granted: 1999-05-01
Abstract: An optical switch serves the purpose of relaying in a specific, selected direction a wavetrain irradiated onto it. Suitable as part of an optical switch is a light-transmitting material in which by applying an electrical field a three-dimensional diffraction structure is generated by means of which the direction of the wavetrain can be varied. An optical switch according to the invention has a material with optically nonlinear characteristics, in which the three-dimensional diffraction structure is stored. The material forms at least one single layer (2) which extends above a substrate (1). Electrodes (3 - 6) are present; the diffraction structure in the layer (2) can be varied by an electrical field which can be applied to the electrodes. A portion of the wavetrain irradiated onto the layer (2) is consequently deflected in accordance with the strength of the electrical field present between the electrodes (3 - 6). <IMAGE>
