Title: Adsorptive separation by pressure variation
Inventor: KAWAI MASAHITO
IPC: B01D53/04
Filed: 1989-06-29
Abstract: PURPOSE:To permit an efficient operation by an equalization process wherein a material supply is communicated at one end with an adsorbing cylinder at the end of its adsorbing process and at the other end with an adsorbing cylinder at the end of its reforming process. CONSTITUTION:Part of the oxygen being fed from a cylinder A is introduced through an orifice 4 into a cylinder B from a product delivery end thereof and the rest thereof is sent through a product delivery valve 6a into a product tank 3 for storage therein. On the other hand, a gas is discharged from the cylinder D through an exhaust valve 7b into the outside air to reduce the inner pressure of this cylinder and the oxygen is passed through the orifice 4 into the cylinder for purging therein. In the next equalization process, the exhaust valve 7b of the cylinder B is closed, while a gas in the cylinder A, together with the material air supplied from an air compressor 2 flowing reversely through a material supply valve 5a, is introduced into the cylinder B from a material supply valve 5b thereof. By this method, a device can be wholly compacted.

IPC: G01K7/24
Filed: 1989-06-29
Abstract: PURPOSE:To easily and rapidly check the disconnection of a thermistor temperature sensor circuit by measuring the resistance values of thermistors sensing heating bodies after a prescribed time from the start of operation. CONSTITUTION:The thermistors 1 to 3 and a dummy resistor 4 for a heater driving structure increasing its temperature by its operation are arranged in positions indicating the temperature rise similar to a body to be measured of the structure and a dummy position. Voltage is impressed from a power supply 5 for measuring the resistance values of respective thermistors 1 to 3 respectively through resistors 6 to 9. The voltage of the power supply 5 is divided by the resistance values of the resistor 6 and the thermistor 1 e.g. and supplied to an analog-digital converter 11. Even when the resistance value is high at the time of a low temperature, the disconnection of the temperature sensor circuit to which the thermistor 1 is connected can be easily and surely detected by detecting the resistance value of the thermistor 1 after a prescribed time from the start of operation by the analog-digital converter 11.

Title: Controlling method for process
Inventor: SAEKI MICHIO
IPC: G05B5/01
Filed: 1981-10-23
Abstract: PURPOSE:To attain quick control without overshooting by increasing a manipulated variable up to its maximum value and calculates a point of time for switching the manipulated variable from an individual condition of a controlled system at time of control operation and feeding back the manipulated variable from its maximum value in accordance with the calculated result to control the manipulated variable. CONSTITUTION:The maximum value of a square wave pulse is supplied as a manipulated variable at the control operation of a controlled system. Power supply 7 is inputted to a buffer amplifier 21 through an inverter 1 and through a buffer amplifier 22 from an input terminal 8 and then inverted and amplified by an inversional amplifier 3. A variable resistor for feedback sets up a parameter and a comparator 4 discriminates whether a set point is S or P to detect a point of time for switching the manipulated variable. A variable resistor 13 is adjusted so that the output of an amplifier 14 is turned to zero to automatically set up differential time. An integrator is connected to the post-stage of the amplifier 14. Thus it is possible to control the process variable of the controlled system to its set point within a short time without generating overshooting.

Abstract: PURPOSE:To achieve the adjustment, by confirming lamp display and performing set, through a variable resistor for the proportional band and zero point of a duty ratio control and a changeover switch for the duty cycle time, in a cooling or heating device. CONSTITUTION:In a controller, the proportional band of operation rate to external temperature can be increased by adjusting a variable resistor VR3 and  increasing the feedback amount to an inverting input of a differential amplifier  6.

Title: Output buffer circuit
Inventor: TANAGAWA KOUJI
IPC: H03K19/003
Filed: 1983-09-16
Abstract: PURPOSE:To decrease the spurious radiation wave by incorporating an integration circuit in an output buffer circuit. CONSTITUTION:The integration circuit is constituted by a resistor 4 connected between an output terminal of the 1st stage inverter 21 and an input terminal of the 2nd stage inverter 22 and a capacitor 5 between input and output terminals of the 2nd stage inverter 22. After a signal inputted to an input terminal 1 is inverted and amolified by the inverter 21, the result is inverted and amplified further by the inverter 22 and also the leading/trailing time of the signal is decided by the time constant of the integration circuit. Thus, the generation of the spurious radiation wave is eliminated because the switching speed of an output signal is limited.

Title: Bumper boring system energized by spring
Inventor: UIDORITSUKU KENTO ERU
IPC: A63D5/00
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To make a bumper overhang in place easily in no time, by holding the bumper at the storage position when a spring passes the center against a driving member, and energizing it upward when a spring is off to the center. SOLUTION: A hollow part 40 moves up to overhanging position by a crank arm 54 and fixes a coil spring 58 to base at one end and opposite end fixes one of the crank arms 54. When the hollow 40 is upwards, that is the structure position, the spring 58 is tensioned to keep the hollow 40 in that position. As the hollow 40 moves to the arrow marked direction, backward and downward, the tension of the spring 58 becomes increased, and the hollow 40 moves to the leading-in, that is storage position, the spring 58 gets longer crossing a driving pin 59 with passing through the center. Lifting the hollow 40 slightly from the center passed state, the hollow 40 flies out to the overhanging position.

Abstract: PURPOSE:To increase the stability of an airframe during gliding and eliminate the manual supporting of both wings by supporting an airframe on a carriage while it is gliding until take-off and separating it from the carriage at take-off. CONSTITUTION:An airframe is put on a carriage 3 before flight, a locking lever 6 is projected toward the inside of a fuselage 2, and an operating piece 7a of a solenoid 7 is inserted into a locking piece 6a to fix the fuselage 2 to the carriage 3.
