Title: Automatic measuring and centering apparatus
Inventor: NARITA MASAMICHI
IPC: G01B21/02
Filed: 1983-08-08
Abstract: PURPOSE:To perform the measurement of the size of a large item to be machined and the centering work thereof readily, by providing a mechanism, which chucks the outer diameter of a work, and providing sensors, which simultaneously measure the surface to be machined. CONSTITUTION:The measurement of the total length L of a work 1 is performed by the following way. Non-contact sensors 35, 35a, 35b and 35c are set on the same vertical surfaces of measuring and centering units 7A and 7B. The size LX between the non-contact sensors is measured. Then the units 7A and 7B are driven by motors 10A and 10B and moved in the directions of surfaces to be machined 1A and 1B. When a distance between any of the sensors and the surface to be machined becomes SX, the movement of the units 7A and 7B is stopped. Meanwhile, the amounts of movement lA and lB of the units 7A and 7B are measured by scales 60A and 60B at the lower surfaces of the units 7A and 7B. Thus the total length L of the work is obtained. The centering is performed by chucking the outer diameter by a chuck that is not shown, with the work 1 being lifted.

Title: Intermediate frequency amplifier
Inventor: SAIKAI TOSHIO
IPC: H04B1/10
Filed: 1983-08-05
Abstract: PURPOSE:To measure the characteristic of a delay time by a sweeping method at the normal level of an input signal and to prevent squelch malfunction at the time of a low input level by adding a variable band pass filter and a band- variable controller to an intermediate frequency amplifier. CONSTITUTION:An input signal from a terminal 1 is amplified by variable gain amplifiers 2-4, a fixed gain amplifier 5 and an interference amplifier 7, limited at its band by the variable BPF13 and converted into a DC signal by a detector 9, and the DC signal is applied to an AGC voltage amplifier 10. The amplifier 10 applies AGC voltage to the amplifiers 2-4 so that the output signal level of a terminal 6 is kept constant irrespective of the variation of the input signal level to control the gain of the amplifiers 2-4. The AGC voltage is inputted to the band-variable controller 14 and a squelch detector 11. When the input signal to the terminal 1 is in the normal level, the controller 14 expands the band of the BPF13 and measures the delay time characteristics over wide frequency by the sweeping method. At the low level input signal, the controller 14 narrows the band of the BPF13 and prevents the squelch detector from malfunction due to an interference wave.

Title: Driving gear of or piezoelectric actuator for vehicle
Inventor: HARA YOSHIMICHI
IPC: F16F9/46
Filed: 1989-06-07
Abstract: PURPOSE:To prevent generation of an unexpected drive condition or the like by setting a testing mode, in which drive voltage of a booster means is applied to a piezoelectric unit, thereafter releasing the testing mode when a condition such as the lapse of time or a predetermined condition related to a running condition is established. CONSTITUTION:When a vehicle is running, output voltage of an on-vehicle power supply is boosted in a booster means M2, and drive voltage is applied in the desired timing to a piezoelectric unit MP by an in-running applying means M3 to drive a piezoelectric actuator M1 by extending and contracting the piezoelectric unit MP. On the other hand, when a testing mode is set by a mode setting means M4 in external operation, a testing mode applying means M5 is actuated to apply the drive voltage of the booster means M2 to the piezoelectric unit MP. Thereafter, when a condition such as the lapse of time or a predetermined condition related to a running condition of the vehicle is established, a testing mode release means M6 is actuated to release setting of the testing mode, and application of the drive voltage is only executed by the in-running applying means M3. Thus, generation of an unexpected drive condition of the piezoelectric actuator for the vehicle, while it is running after a drive test, can be prevented.

Title: Method of reducing dynamic overvoltage in ac power source line
Inventor: GEAHARUTO GIYUUTO
IPC: H02J3/36
Filed: 1985-07-03
Abstract: Where different 3-phase systems are connected to each other via two static converters having an intermediate direct-current circuit, the exchange of power via the intermediate direct-current circuit can be interrupted by a severe disturbance, for example by failure of a static-converter or by line or busbar faults causing a short-circuiting of one of the static converters. This interruption means a change in the balance of effective power and, associated with this, a shedding of reactive load for the other undisturbed 3-phase system. To reduce high dynamic overvoltages which can lead to plant components being endangered or to operational disturbances, the firing angle of the static converter remaining in operation is regulated with dependence on the alternating voltage of the alternating-current system connected to this static converter, in such a manner that the overvoltage is reduced. This is carried out by regulating the current. The firing angle can be adjusted simultaneously with the short circuiting of the intermediate direct-current circuit by means of a short circuit device.

IPC: B66F3/00
Filed: 1987-06-12
Abstract: PURPOSE:To simplify the structure by combining a cylinder made of superconducting material and annular superconducting floats where magnets for producing magnetic field are arranged around the superconducting cylinder. CONSTITUTION:When a cylinder 2 made of superconducting material is erected vertically and coolant 6 having temperature lower than the critical temperature of superconducting material is fed through a coolant inlet/outlet 4 at the lower end, the portion of the superconducting cylinder 2 contacting with the coolant 6 is brought into superconducting condition. When power is fed to a magnet 1 under this condition and flux is produced, flux is confined in the cylinder 2 and rises to non-superconducting portion of the cylinder 2(portion not contacting with the coolant 6) and spreads to the outside of the cylinder 2. When an annular superconductor(containing coolant 6 at the inside) is fitted over the cylinder 2 and moved downward, floating force is produced through repulsion against the flux at the portion where the flux spreads to the outside of the cylinder, and the annular superconductor 5 stops in place. Then the coolant 6 id taken in/out of the cylinder 2 so as to vary the level of coolant 6 thus varying the floating height of the superconductor 5.
