Abstract: PURPOSE:To drive surely a high dielectric strength field effect transistor (TR) under insulation conditions and a simple circuit by connecting the two high dielectric strength field effect TRs in series in opposite polarity and providing the connected TRs to the positive side and the negative side of input terminals respectively to provide an isolated drive voltage between gates of the four field effect TRs. CONSTITUTION:In order to drive a switch means 21, a TR1 is turned on, a voltage +V is fed to a light emitting diode LED, which is lighted and an insulated voltage is generated to a solar battery SB, the four FET TRs are turned on at the same time by giving the voltage eg to the midpoint of resistors R1, R2 and the gates G of the high voltage dielectric strength field effect TRs Q1, Q2, Q3 and Q4 and then the input signal is fetched. In order to turn off the means 21, it is attained by simply interrupting the supply of the voltage eg. The insulation between the input and output is attained by the high dielectric strength field effect TRs of one set two pieces in this way and the drive circuit is insulated, then no mutual interference between channels exists and the circuit is resistant to noise. In order not to decrease the input impedance, a high resistor of >=1M ohm is used for the R1 and R2.

Inventor: OGAWA YUJI
IPC: C21C5/46
Filed: 1993-02-08
Abstract: PURPOSE:To directly predict the development of slopping without delay of time by measuring an emission spectrum of the peculiar element in molten slag with an optical fiber arranged in the inner part while blowing gas into a refining vessel from a tuyere. CONSTITUTION:The tuyeres 4-1, 4-2 are arranged at the intermediate part and the uppermost part of the inner wall of the refractory in a converter body 1 and in these tuyeres, the optical fibers (not shown in the figure) are arranged. While the molten steel 2 is refined through molten slag 3 by using this converter 1 and the gas is blown from the tuyeres 4-1, 4-2, the emission spectrum intensity of the peculiar element, e.g. Na, contained in the molten slag 3 or the molten steel 2 is measured with spectroscopes 6-1, 6-2 through the optical fiber. At the time of observing a prescribed variation in this spectrum intensity, the development of the slopping is detected, and based on this predicted signal, the necessary measure to avoidance of the slopping is tried. By this method, the yield of the total steel tapping quantity, the stability of blowing, the recovery ratio of OG gas are improved.

Title: Flow rate detector
Inventor: WATANABE SHINICHI
IPC: G01F1/20
Filed: 1988-01-29
Abstract: PURPOSE:To improve the accuracy for detecting flow rate by detecting the rotational frequency of a spherical body which turns together with a fluid to be detected, correcting a rotational frequency detecting signal by a temperature detecting signal of the fluid, and using it as a flow rate signal. CONSTITUTION:When water flows into an eddy current chamber 13 from the direction as indicated with an arrow H, a magnetic spherical body 14 turns in the direction as indicated with an arrow G together with an eddy current. When the magnetic spherical body 14 passes through a permanent magnet 16 and a magneto-resistance element 15 side, a magnetic field of the permanent magnet 16 is curved. By using a signal generated from the magneto-resistance element 15 in this case, the speed of revolution is detected by a rotation frequency detecting device 17. On the other hand, water temperature data is obtained by a water temperature sensor 18. The rotational frequency from the rotation frequency detecting device 17 and the water temperature data from the water temperature sensor 18 are corrected by a correcting device 19, and corrected flow rate data 20 is obtained. In such a way, the flow rate can be detected with high accuracy.

Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a telephone system whose location is easily recognized by sounding the telephone system in the call mode switched from a vibration mode into the sounding mode from other telephone system. SOLUTION: In the case that a speed state is not caused even after calling in the vibration mode is made for a prescribed time or over, a control section 2 transits to an external message waiting state and allows a reception section 4a to receive a prescribed control signal from a sender and uses a MODEM 5 and a TDMA 6 to detect the control signal, then controls a PCM CODEC 8 or the like so that the call mode is switched from the vibration mode to the sounding mode for a prescribed time. Thus even when the telephone system is left somewhere and the location is not recognized, other telephone system sends a call tone to the telephone system whose location is not recognized and the location is easily recognized.

Title: Light emitting diode as point light source
Inventor: SONE TOSHINORI
IPC: H01L33/30
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a light emitting diode as a point light source having a small aberration. SOLUTION: In the light-source light emitting diode 10, a reflective layer 14 for reflecting light that is emitted from an active layer 18 and is directed toward a substrate 12 toward a light exit surface 36 is provided between the active layer 18 functioning as a light emitting layer and the substrate 12 at a position spaced by a distance d from the active layer 18 corresponding to 1/20 or less of a diameter (emitted light diameter) D of a light exit part 38. For this reason, light directed toward the substrate 12 is also reflected by the reflective layer 14 and radiated from the light exit surface 36, whereby a high light emission output can be obtained.  At this time, since the distance d between the active layer 18 and reflective layer 14 is made to be as small as 1/30 of the emitted light diameter D, an aberration to be determined by a distance (i.e., a distance between two of light sources in the light-source light emitting diode 10) between the active layer 18 and a virtual light emitting position Si of the reflected light can be made to be sufficiently small with respect to the emitted light diameter D.

Title: Solar heat utilization device
Inventor: HATSUTORI MASAJI
IPC: F24S90/00
Filed: 1978-02-24
Abstract: PURPOSE: To control heat collection efficiently and to reduce the work time by detecting the temperature in a tank at desired time intervals by a temperature detector and continuously operating a heat collection pump only when the detected value is high.  
     CONSTITUTION: The temperature of hot water in a reservoir tank 2 is measured by a thermistor 6, and the measurement is compared with that at five minute before. When the measurement at this time is lower, which indicates no heat collection, a heat collection pump 3 is stopped and the next function is prevented for thirty minutes. When the measurement at this time is higher, the measurement is checked if it is higher or lower than 80°C. If it is higher than 80°C, the pump 3 is stopped and heat collection is finished because further rise in hot water temperature would cause boiling or danger of scald. If the temperature is lower than 80°C, the pump 3 is operated continuously.
