Title: Reverse power flow preventing method during parallel operation
Inventor: HIROSAKI MASANAO
IPC: H02J3/38
Filed: 1989-06-16
Abstract: PURPOSE:To prevent reverse power flow reliably by driving a regulating load having quick response upon detection of power at power receiving point in a commercial power source system or upon detection of load variation during parallel operation of the commercial power source system and non-utility generating system. CONSTITUTION:Power is fed from a commercial power source 1 in a commercial power source system A through a primary circuit breaker 2, a CT 3, a PT 4, a transformer 6 and a secondary circuit breaker 7 to a bus 8 and a common bus 12. On the other hand, power is fed from a non-utility generator 9 in a non-utility generating system B through a circuit breaker 10 to a bus 11 and a common bus 12. Upon detection of reverse power through the CT 3 and the PT 4, a quick response power converter 18, e.g. a thyristor, is driven through a controller 17 to feed power from the bus 12 through a transformer 19 to a regulating load, e.g. an electric boiler, thus absorbing the generated power. By such arrangement, reverse power flow to the commercial power source system A can be prevented reliably even if the governor in the non-utility generating system B responds with a time lag.

Title: Device for measuring semiconductor characteristic
Inventor: MUNAKATA TADASUKE
IPC: H01L21/66
Filed: 1985-07-12
Abstract: PURPOSE:To enable the non-breakdown measurement of the surface potential by a method wherein a semiconductor sample is irradiated with a modulated light beam, and the frequency dependance of the amplitude of obtained electric signals is obtained; thereby, the surface potential of the sample is calculated on the basis of a specific expression of relation. CONSTITUTION:A photon beam 10' emitted from a light source 6 is modulated into a specific frequency by a photo modulator 5, part of which is split by a beam splitter 7 and then converted into electric signals by a photo detector 8. This signal is used as the phase reference to the photo voltage. On the other hand, most of light comed into the semiconductor sample 2 through a clear electrode 3 after reflection on a reflection mirror 4. The generated photo voltage is detected by the electrode 3 and a sample table 1, and its amplitude and its phase are found out by a phase detection amplifier 9. Next, scanning the drive frequency with an oscillator 1 can yield the determination of the frequency dependance of the amplitude or phase of the photo voltage. Thereby, the specific attenuation of the potential difference or the amplitude is obtained, and the surface potential of the sample is calculated from this frequency on the basis of a specific expression of relation.

Filed: 1990-06-11
Abstract: PURPOSE:To recover the degree of balance of a balanced cable by measuring a ground impedance of each core wire caused due to the deterioration in the insulation of the balanced cable and correcting its unbalanced component automatically so as to balance the impedance. CONSTITUTION:A control section 29 sets an impedance Zx. of a variable resistor 27 to be Zx=Z2.Z3/Zs (Z2 is an impedance of the balanced core wire 42 with respect to ground, Z3 is an impedance of the balanced core wire 43 with respect to ground, and Zs is ¦Z2-Z1¦) and sets a variable resistor 28 to be opened (impedance is infinite) when the impedance of a balanced core wire 42 with respect to ground is larger than the impedance of the balanced core wire 43 with respect to ground (Z2>Z1). The control section 29 sets the impedance ZY of the variable resistor 27 to be opened and sets the variable resistor 28 to be Z2.Z3/Zs conversely when the impedance of a balanced core wire 42 with respect to ground is smaller than the impedance of the balanced core wire 43 with respect to ground (Z2<1). Thus, unbalanced ground impedance of the core wires is eliminated.

Title: Heat pump hot-water supplier
Inventor: IMABAYASHI SATOSHI
IPC: F24D19/10
Filed: 1984-07-23
Abstract: PURPOSE:To improve operating efficiency while guaranteeing the amount of hot-water securely by a method wherein the operation of an auxiliary heater is controlled by detecting the evaporating temperature of a heat pump and the amount of remaining hot-water. CONSTITUTION:The setting point of an evaporating temperature detecting sensor 17 is determined to be the point of intersection TEI of a ling L1 showing the heating capacity of the heat pump and the line L2 showing a heat load when the amount of remaining water is zero. In case the evaporating temperature of the heat pump is higher than the set temperature TEI, the operation of the device is effected by only the heat pump. When the evaporating temperature has reduced lower than the set temperature TEI, the switch 17' of the evaporating temperature sensor 17 is closed. In this case, the switch 14' of the remaining hot-water detecting sensor 14 is closed if the amount of remaining water is zero and the auxiliary heater 10 becomes conductive whereby the heating capacity becomes L4 in the diagram and the hot-water temperature is guaranteed. When the amount of remaining hot-water is sufficient, the switch 14' is opened and the hot-water temperature can be guaranteed by using only the high efficiency heat pump without using the auxiliary heater 10 since the heating load L2 is smaller than the heating capacity L1 of the heat pump.

Title: Automatic flaw detecting method for tube body
Inventor: UJITA YOSHIHISA
IPC: G01N29/26
Filed: 1990-06-12
Abstract: PURPOSE:To bring a shoe into contact with a tube under inspection stably by providing a sensor for detecting the contact between a shoe and the tube under inspection at the front and rear parts of the tube under inspection in the axial direction of the tube, and controlling the direction of the force of a cylinder for supporting the shoe in a cantilever mode based on the contact signal. CONSTITUTION:A cylinder 6 is operated by the detected signal at the tip of a tube under inspection 3 from a tip sensor 4. Then, a part of a shoe 2 comes into contact with the outer surface of the tip part of the tube under inspection 3. A front end sensor 7 of the shoe which supports a probe 1 detects the contact, and the operation of the cylinder 6 is stopped. At the same time, the direction of the force of the cylinder 6 is controlled. Thus the contact between the shoe 2 and the tube under inspection 3 becomes stable. The rear end of the tube 3 is also controlled by the same way through a rear-end sensor 8, and the shoe 2 is stably separated from the tube 3. As a result, parts wherein flaw detections are not performed at the tube end parts can be made almost zero in automatic flaw detection with the minimum number of the probes.
