Title: Inspection of heating state by reflow furnace
Inventor: SAEKI TAKAHARU
IPC: B23K35/00
Filed: 1988-07-28
Abstract: PURPOSE:To prevent an increase in the generation of defective products by a method wherein radiation thermometer is installed so as to face a passage of an object to be heated at an outlet part of a reflow furnace in order to detect whether the object to be heated is passing through a temperature-measuring position of the radiation thermometer and, while the object to be heated is passing, its temperature is detected. CONSTITUTION:Radiation thermometers 6 are installed at an outlet part of a reflow furnace 3; a temperature of objects 1 to be heated is measured. The radiation thermometers 6 are installed at the upper part and lower parts of a passage of the objects 1 to be heated, and are installed obliquely from the outside of the reflow furnace 3 toward the inside of the furnace. While the objects 1 to be heated are passing through a temperature-measuring position of the radiation thermometers 6, their temperature is measured; when the objects 1 to be heated are not passing, a surface temperature of plane heaters 4 is measured; this measured temperature is lower when the objects 1 to be heated are passing; the measured temperature is changed suddenly at their boundary. Accordingly, whether the objects 1 to be heated are passing can be detected from this temperature change; when a lower measured value is taken out, a temperature of the objects 1 to be heated can be detected. Thereby, an abnormality of a heating state in the reflow furnace 3 can be discovered at an early stage; it is possible to prevent an increase in the generation of defective products.

Abstract: PURPOSE:To feed water into a reactor core and promote its cooling by providing a means of temporarily relaxing pressure drop occurring in a pressure vessel at the time of a LOCA and controlling pressure reduction boiling in a lower plenum and a reactor core only at that time. CONSTITUTION:If a tube connected to a nozzle 20 is bursted and an accident in which coolant flows out from a pressure vessel occurs, a ECCS 31 is normally operated, a valve 33 is opened, a sealing water pump 34 is driven and the cooling water in a tank 32 is fed into an upper plenum 15 from a spray header 35. On the other hand, a pressure signal measured by a pressure detector 37 is compared with prescribed pressure in an arithmetic circuit 44 on a pressure reduction means 36. When the pressure measured in the circuit 44 is lower then the prescribed pressure, an operating signal of a pump 49 and an solenoid valve 50 is output in an AND circuit 46. Since the ECCS 31 is operated, at the same time the drive signal of the sealing water pump 34 is input in the circuit 46. Therefore, the circuit 46 outputs the operating signal to the pump 49 and the solenoid valve 50 respectively.

Abstract: PROBLEM TO BE SOLVED: To observe an optometric image invariably at the fixed brightness. SOLUTION: The eyeground Er of an eye E under optometry is illuminated by the light flux emitted from an observation light source 9, and an eyeground reflected image is formed on image pickup elements 8r, 8g, 8b via an apertured mirror 2, a photographing aperture 3, a focus lens 4, a photographing lens 5, and a color separating prism 7. This electric signal is amplified at the prescribed amplification factor through a signal amplifying means 16, is fed to an image control means 17, and is displayed on a television monitor 18. A photographer keeps the brightness of the eyeground image Er' displayed on the television monitor 18 constant while observing the television monitor 18 and adjusts the light quantity applied to the eye E and the picture quality of the television monitor 18.  When the light quantity emitted from the observation light source 9 is increased as the applied voltage is increased, the amplification factor of the signal amplifying means 16 is reduced. When the light quantity of the observation light source 9 is decreased, the amplification factor is increased, thereby the brightness of the screen of the television monitor 18 is kept constant, thus noise is reduced, and the picture image is improved.

Title: Full-wave rectifier circuit
Inventor: TAJIMA TATSUHIKO
IPC: H04L7/027
Filed: 1994-08-09
Abstract: PURPOSE:To obtain a compact circuit capable of corresponding to the acceleration of an input AC signal by connecting a 1st transistor(TR) for positive clip operation and a 2nd TR for saturated current operation to an input signal in parallel, adding an output from the source electrode of the 1st TR and an output from the drain electrode of the 2nd TR and outputting the synthesized signal. CONSTITUTION:This full-wave rectifier circuit is constituted only of two FET TRs 31, 32. The FET TR 31 for positive clock operation cuts off the negative side of an input wave by the bias voltage Vg of a gate G and extracts only the positive part from its source electrode S. The FET TR 32 for saturated current operation saturates the positive side of the input wave, inverts the polarity of only the negative part and extracts the inverted wave. When output waves from both TRs 31, 32 are added, an output added by inverting the polarity of only the negative part of the input wave without inverting the positive part is obtained. The level of the resultant output is adjusted by the DC bias voltage Vd of the drain D of the TR 32.

Title: Current control method
Inventor: TANIZAKI TOSHIMASA
IPC: H02J3/10
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To adjust the current in some blocks of a distribution line as required by providing first and second controllable current sources between both ends of the block, and operating the polarity or the phase of these output in roughly reverse polarity or in reverse phase. SOLUTION: An adjusting current 18 of a controllable current source 81 and a compensating current 17 of a controllable current source 71 are the currents in roughly reverse phase, even though there is a difference by the phase difference amount between a voltage V3 at a point A and a voltage V5 at a point B, and a current 18 injected from the point B by the controllable current source 81 is absorbed at the point A by the compensating current 17 of the controllable current source 71. The two controllable current sources perform only the control of reactive power, because they both supply currents which are 90 deg. shifted in phase with respect to the voltage at the points provided with the controllable current sources.  As a result, this method does not require a power source to the supply power, and it is sufficient for the device to only process the loss due to the drop of the currents and the element, so that one of small power processing capacity can be used.
