Title: Three-phase full-wave rectifier
Inventor: SUZUKI YOSHIO
IPC: H02M7/12
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To prevent the extreme rise of the output voltage of a full-wave rectifier even when the load is light, by monitoring the output voltage of the rectifier with a prescribed hysteresis, and intermittently operating a rectifier circuit when the rectifier makes voltage-zero switching operations. SOLUTION: A hysteresis comparator circuit 9H sets a set value Eo for controlling constant-voltage, a voltage which is several percentage as high as the set value Eo as a set first voltage value En, and a voltage which is several percentage as high as the set value En as a set second voltage value Em. A diode Co makes energy flow in one direction and, when a load 8 is light, the output voltage F of a three-phase full-wave rectifier 101 rises. When the output voltage E rises to the set value Em, the operation of a three-phase full-wave rectifier circuit 6 is stopped and the energy which raises the output voltage E to the set value Em is consumed by the load 8, a control circuit 91, etc. When the output voltage E becomes the set value En or lower, the occurrence of an overvoltage can be prevented by intermittently oscillating the rectifier circuit 6 to restart the circuit 6.

Title: Communication equipment
Inventor: OCHIAI MASAHITO
IPC: H04N1/32
Filed: 1991-05-14
Abstract: PURPOSE:To devise the communication equipment such that a line is not interrupted on the way of pages of communication and both a sender side and a receiver side allow to receive the service through the use of other channel optionally even during the communication. CONSTITUTION:Upon the receipt of a UUI to which a page identifier and a transmission picture capacity are added by a receiver side, a CPU 2 discriminates whether or not the reception of the page in the bulk transfer is available based on the residual quantity of a reception output memory 5, a print speed of a printer section 10 and a bulk transmission speed. Since the bulk transmission speed is twice the usual communication speed, when the print of the printer section 10 is slow, the capacity of the reception output memory is saturated and the line is interrupted on the way of the page. Then the bulk transfer reception is implemented only when the specific condition is established. Furthermore, whether or not the usual reception is available is discriminated by replacing the bulk transfer speed with the usual communication speed.

Title: Agitator for reaction tube
Inventor: HIRABAYASHI MASAYOSHI
IPC: G01N35/02
Filed: 1986-06-13
Abstract: PURPOSE:To obtain an agitator with excellent agitation effect which can prevent mutual contamination of reaction tubes, by vibrating a reaction disc in the direction of forward or backward rotation by a value half the movement of a reaction tube by a vibration means as each reaction tube is moved with the reaction disc to stir a reaction liquid by an air jet discharged from a nozzle. CONSTITUTION:A reaction disc driving means 10 is operated to turn a reaction disc 7 forward intermittently by one reaction tube 8 at a time. Under such a condition, an operation signal is outputted from the means 10 and activates the reaction disc 7 stopped by 6.5sec of the 10sec cycle to vibrate in the direction of forward or backward rotation by a value half the movement of one reaction tube 8 for about 3.5sec. With the start of the vibration, a nozzle 3 discharges an air jet. Upon the end of the vibration, the discharge of the air jet is stopped. A jet port 11 of the nozzle 3 reciprocates between the intermediate point between adjacent two reaction tubes 8 and the inside of an opening of a reaction tube 8 ahead thereof to inject the air jet to a reaction liquid 9. The air jet is blown against the inner wall of a cylinder of the reaction tube 8 intermittently to agitate the reaction liquid 9.

Title: Objective lens for microscope
Inventor: SUZUKI TOSHINOBU
IPC: G02B27/00
Filed: 1988-06-06
Abstract: PURPOSE:To obtain the excellent contrast of an image which is modulated by an optical modulator by moving the optical modulator integrally with a moving lens group. CONSTITUTION:The exit pupil position E of the objective is nearby the joined surface of a parallel plane plate and a positive lens and a cemented lens move in one body. Therefore, when the positive lens of a lens group L2 moves toward an object plane M for cover glass thickness correction, the exit pupil position E of the objective also moves toward the object plane M. At this time, the cemented lens also moved toward the object plane M, so a phase film (optical modulator) P never shifts from the exit pupil position E. Further, when the positive lens of the lens group L2 moves to an image side, the exit pupil position E also moves to the image side, but the cemented lens also moves to the image side, so the phase film P never shifts from the exit pupil position E. Consequently, the ring of the phase film P need not be made thick, so the contrast of an image for a phase difference observation is improved.

Abstract: PURPOSE:To provide a driving roller conveyor which can give sufficient carrying power to a carried article though the whole driving roller conveyor can be simply and inexpensively composed and simply controlled, and can quickly stop the driving roller simultaneously with switching from driving to nondriving. CONSTITUTION:The forced rotation of a driving roller 20 is transmitted to a transmitting roller 60 abutting elastically against the roller 20, and the roller 60 is thereby forcedly rotated in a reverse direction. The forced rotation of the transmitting roller 60 is transmitted to a loosely rotating roller 50 abutting elastically against the roller 60, and the roller 50 is thereby forcedly rotated in the same direction as the driving roller 20. The whole of the driving roller 20 and the loosely rotating roller 50 are turned into a forcedly driven state. When the forced rotation of the driving roller 20 is stopped, the rotation of the transmitting roller 60 can be quickly stopped by making frictional resistance reduce its inertia rotation, and moreover the rotation of the driving roller 20 by which the transmitting roller 60 is abuttedly energized through elastic force and of the loosely rotating roller 50 can be also quickly stopped by reducing the inertia rotation.

Abstract: PURPOSE:To maintain a pressure of gas with a less amount of purge gas consumption by providing purge gas annular grooves, connected to a purge gas line, and circular annular rings which are fit-inserted into a fine clearance of these annular grooves and slided in a direction at a right angle with the axial direction. CONSTITUTION:When purge gas is supplied into the first and second purge gas annular grooves 14a, 14b from the outside to pass through a purge gas line 15, an upper surface of the first circular annular ring 18a and the first sliding member 19a are placed in a strong surfacecontact condition with a lower surface of the first ring case 16a by resilient force of a spring 17 and a differential pressure between purge gas in the groove 14a and the inside of a vacuum pump mechanism 6. Under this condition, when vibration is generated in a direction at a right angle with the axial direction following rotation of a rotor 4, the ring 18a is slided in the side of a case 16a to follow up to vibration of the rotor 4 through the member 19a, so that a fine clearance is maintained by the ring 18a and the rotor 4. A similar surface contact condition is generated also in the groove 14b, and in this condition, by the follow up action to vibration by rotation of a shaft 10, a fine clearance is maintained between the second ring 18b and the shaft 10.
