Title: Comparing circuit
Inventor: IKEDA MASAHARU
IPC: H03K17/00
Filed: 1983-09-05
Abstract: PURPOSE:To prevent the drop-out of a demodulated sound signal and the mixture of impulsive noise at the moment of switching by using two comparators different in hysteresis. CONSTITUTION:In case of reception by a diversity system, sound outputs of two receiving parts A and B are inputted to two comparators 15 and 16 having the same hysteresis characteristic. The hysteresis characteristic between a comparison input voltage V1 and a comparison output 8 and that between a comparison input voltage V2 and a comparison output 9 have thresholds shifted to the extent so that hysteresis widths are equal to each other and hysteresis ranges overlap each other. Therefore, the area where electronic switches 10 and 11 con- trolled in accordance with sound inputs by outputs of comparators 15 and 16 are turned on simultaneously is provided to prevent the drop-out of the sound signal and the impulsive noise. Inverters 61 and 62 are connected to the outputs of comparators 15 and 16.

Title: Charge transfer device
Inventor: MIWATA KAZUO
IPC: H01L21/339
Filed: 1987-06-29
Abstract: PURPOSE:To reduce a reset noise component by a method wherein a region low in potential is provided adjacently to a charge detecting region under a gate of a reset transistor. CONSTITUTION:The gates of a reset transistor are composed of two reset gates 15 and 16 separated by an insulating film 13 and an impurity layer 17 of a P-type is formed under the gate 15 close to a charge detecting region 10. The reset gates 15 and 16 are structured as mentioned above, SO that the potential under the gate 15 is lower than the potential under the gate 16. Therefore, when a reset transistor conductive turns non-conductive, carriers under the gates of the reset transistor flow toward a drain region 14. By these processes, a noise component can be decreased.

IPC: H01L21/205
Filed: 1986-07-11
Abstract: PURPOSE:To prevent liquid from flowing out of a container through a tube by a method wherein a blocking part is provided by constricting a part of a lead tube which leads bubbling gas into the liquid and a floating stopper which has a smaller specific gravity than the liquid and is so shaped as to block the blocking part is provided. CONSTITUTION:There are provided a valve 6 for leading out vapor and bubbling gas, a blocking part 7 consisting of a narrow part of a tube 4, and a floating stopper 8 which is so shaped as to block the blocking part 7 and has a specific gravity small enough to float on liquid 2. Hydrogen pushes down triethylindium 2 or the liquid in the tube 4 and the floating stopper 8 floating on it and is spouted out into the triethylindium 2 in a container 1 to make it bubble. Thus the triethylindium 2 is vaporized and the vapor and the hydrogen containing the vapor are lead out through the valve 6 and supplied to demanding parts. If the triethylindium 2 in the container 1 flows along the tube 4 and rises up in the lead tube 4, the floating stopper 8 floating on it also rises and blocks the blocking part 7 of the tube 4 so that the triethylindium 2 can no longer go up.

Abstract: PURPOSE: To obtain a small-sized isothermal connector in which highly accurate measurement can be carried out with a short set time by providing a thermally conductive thermocoupling member at a joint of a thermocouple connector and an isothermal connector and setting the thermal capacity of the isothermal connector higher than that of a corresponding connector. CONSTITUTION: A thermoelectromotive force generated from a thermocouple 12 is fed through a thermocouple connector 16 and an isothermal connector 24 to a measuring circuit 22. In order to suppress the measurement error caused by two thermoelectromotive forces generated through contact of metals at electric joints 26, 18, temperatures at the joints 26, 18 are equalized to minimize the difference between two thermoelectromotive forces thus preventing the thermoelectromotive force generated from the thermocouple 12 from having adverse effect on the measurement. Furthermore, both the joint 26 and the temperature sensor 28 are thermally coupled with a thermally conductive part 30 to bring about an isothermal state and the output signal from the sensor 28 is measured at the circuit 22 thus compensating the thermoelectromotive force at the joints 26, 18. The set time is shortened by setting the thermal capacity at the joint 26 higher than that at the joint 15.

Title: Stabilizing circuit for screen display
Inventor: SUZUKI HIROYUKI
IPC: H04N5/44
Filed: 1994-07-18
Abstract: PURPOSE:To make a screen display stable by providing a signal a decision circuit detecting a reception signal level and converting it into a voltage so as to use a synchronizing separator circuit for a ground wave in common for a BS signal without use of a channel tuning microcomputer. CONSTITUTION:A transistor (TR) Q2 decides a C/N detection level. The decided voltage level is used for a threshold level for signal discrimination. When the C/N detection output voltage is a set optional voltage level or over, since a TR Q3 is turned off, a signal from a base band output is fed to an image processing circuit 3 and a synchronizing separator circuit 6 without being attenuated and usual screen output processing is conducted. When the C/N detection output voltage drops below the set arbitrary voltage level, the TR Q3 is turned on and a signal from a base band output is divided by resistors R4, R5 to be attenuated to an optional amplitude. Since the base band signal is attenuated, it is reduced that the synchronizing separator circuit 6 mis-decides a low frequency noise to be a synchronizing signal. Thus, an image display circuit 7 is operated correctly.
