Filed: 1992-06-30
Abstract: PURPOSE:To enhance the prevention of buckling, the torque transmissivity and the cold process ability by using a highly elastic member made of Co-Ni-Cr- Fe alloy as a core member and by covering the core member with a synthetic resin film. CONSTITUTION:A core member 4 made of highly elastic metal which is Co-Ni- Cr-Fe metal, is covered thereon with a cover part 5 made of a synthetic resin so as to form a medical guide wire. The elastic modulus of Co-Ni-Cr-Fe alloy is limited to a value in a range from 70 to 160kgf/mm<2>. Further, the forward end part of the core member 4 is tapered so that it becomes thinner toward the front end thereof so that the flexibility of the core member 4 gradually increases toward its front end. This medical guide wire is excellent in torque transmissivity with substantially no residual strain caused by curving, and is also satisfactory in manipulatability. Further, the front end part is excellent in cold process ability, and accordingly, may be deformed in a shape corresponding to a desired part even though it is covered with a synthetic resin.

Title: Hot water supplying machine provided with additional heating function of bath
Inventor: HAMAYA MASARU
IPC: F24H1/28
Filed: 1982-09-30
Abstract: PURPOSE:To prevent bath water from being sucked up from the hole formed in a heat exchanger and flowing backward to a service water pipe by a negative pressure of a water heater, by providing a water supply opening at the upper surface part or the upper side surface of the water heater and also providing a mounting pipe of a vacuum breaker at the water supply opening or in the vicinity thereof. CONSTITUTION:When suspension of water, and the like of a service water pipe 16 occurs when a hole is formed in a heat exchanger 22, a vacuum breaker 27 provided at the upper surface part or the side surface uppermost part of the water heater 15, is opened to suck up air. Because the air is sucked up in the water supply opening 13 at a shortest distance and instantaneously, the pressure within the water heater 15 does not become negative. Upon this occasion, a water head difference exists between the hot water supply can body 15 and the bath 21 and hence the water level of the hot water can body 15 is higher than that of the bath 21. The refore, the hot water within the water heater 15 is not pushed out into the bath 21 through the hole formed in the heat exchanger 22, and the bath water within the bath 21 does not flow backward through the hole formed in the heat exchanger 22. Leakage of water from the heat exchanger 22 continues up to an overflow surface A of the bath 21, in which the water level of the bath 21 becomes equal to the water level of the water heater 15.

At this time, the N type diffused layers 13 and 15 are formed by a process after that for the N type diffused layer 20. Then, since an isolation wall 8 disappears between the crossover 22 and the transistors 21, 23, the area becomes small. Besides, the N type diffused layer 20 can be reduced in layer resistance; therefore the resistance value of the lower layer wiring can be reduced.

Title: Ultrasonic inspection device
Inventor: MATSUSHIMA TETSUYA
IPC: G01N29/30
Filed: 1987-07-13
Abstract: PURPOSE:To amplify a received signal consisting of reflected pulses from any distance with low noise and low power consumption without any saturation by providing a transistor (TR), an ultrasonic vibrator, a bias current control part, etc. CONSTITUTION:A bias current control part 40 performs control so that a collector bias current Ic to the TR 1 of a preamplifier has a maximum value ever time an ultrasonic pulse is incident on the ultrasonic vibrator and decreases monotoneously with time until a next ultrasonic pulse is incident thereon. Further, a reflected pulse which is reflected in a body to be inspected to return and has small delay from the point of time of the ultrasonic wave pulse incidence is short in propagation distance and therefore small in attenuation, and the amplitude of the receiving signal is large. For the purpose, the current Ic is made large so as to evade saturation. When the delay is large, on the other hand, the current Ic is made small. Therefore, variation characteristics of the current Ic eliminates saturation with a large-amplitude receiving signal, improves the S/N of the small-amplitude receiving signal, and reduces the power consumption.

Abstract: PURPOSE:To realize a high-speed operation for a CMOS Schmitt trigger circuit, by using the 3-input AND-NOR gate and an inverter. CONSTITUTION:The threshold voltage of the 3-input AND-NOR gate 11 becomes low when the voltage of the node 13 is VDD, and becomes the high threshold voltage VTH when the voltage of the node 13 is VSS. In case the voltage of the input 10 is lower than VTL regardless of the voltage of the input 13 and according to the logic constitution of the gate 11, the voltage of the output 14 becomes VDD. Then the voltage of the output 14 becomes VSS when the voltage of the input 10 is higher than VTH. The delay time of the circuit is equivalent to one stage of the gate 11 and about 1/3 in comparison with the conventional Schmitt trigger circuit. The inverter 12 functions as a feedback circuit which controls the threshold voltage of the gate 11.

Abstract: PURPOSE: To prevent the tapping by shifting the level of a part of blanking section toward the white level of an image and at the same time smoothing a waveform for the rise and fall sections of the level shift.  
     CONSTITUTION: Both the horizontal and vertical driving signals are applied to the gate circuit 3 to be converted into the pulses containing only the vertical synchronous pulse section and horizontal blanking section including the equalizing pulse section. These pulses are applied to the adder 6 after the rise and fall sections approximated with a smooth waveform such as the sine wave, trapezoid wave and the like. The video signal being ciphered is applied to the input terminal 5 of the adder 6, and the both input singals are added together by the adder 6. Thus at least a part of the blanking section of the video signal is shifted toward the white level, and a waveform is smoothed for both the rise and fall sections of the shift of level.
