Title: Surface acoustic wave filter
Inventor: KOMAZAKI TOMOKAZU
IPC: H03H9/64
Filed: 1989-12-28
Abstract: PURPOSE:To obtain a surface acoustic wave (SAW) filter equipped with a much sharper attenuating characteristic by utilizing a sharp attenuating operation based on resonance by providing an SAW resonator equipped with a high Q parallelly to an output side interdigital transducer (IDT). CONSTITUTION:On one piezoelectric substrate 4, DIT 1 and 2 are formed and an SAW resonator 3 is provided parallelly to the output side IDT 2. An electric signal inputted to the SAW filter is impressed to the input side IDT 1, converted to SAW, propagated on the piezoelectric substrate 4 and reached to the output side IDT 2. However, since the SAW resonator 3 equipped with the high Q is provided parallelly to the output side IDT 2, large attenuation is received by a resonance phenomenon when the frequency of the electric signal is corresponding to the resonance frequency of the SAW resonator 3, and the electric signal is not outputted from the SAW filter. Thus, the attenuating characteristic of the SAW filter can be made sharp by the resonance frequency.

Title: Method for electrically stimulating experiment animal and device used therein
Inventor: TAKIOKA HIROSHI
IPC: A61D1/00
Filed: 1990-11-30
Abstract: PURPOSE:To apply electric stimuli to the experiment animal put into a room without generating the acclimatization to the electric stimuli by stepwise increasing the intensity of the current to be passed to the 1st room partitioned by a wall bored with holes. CONSTITUTION:A pawl 10 of a stepping relay of a resistor 7 is fed one each clockwise and is brought into contact with an ensuing terminal 8 by the instruction from a sequencer 11 when the current of the same intensity is passed 30 times for 10 seconds each at, for example, 2-minute intervals when the intensity of the current is desired to be increased at every one hour as an example of setting the conditions for experiment. Since the resistance value changes in such a case, the intensity of the current can be increased by one step. The pawl 10 of the stepping relay of the resistor 7 is sent by one each clockwise at every one hour to change the resistance value by repeating the above-mentioned operations, by which the current intensity is increased stepwise. The current intensity can be stepwise increased 8 times if, for example, the total time for the experiment is set at 8 hours. The currents generated in such a manner flow to a grid 5 on the floor of the 1st room 2a through an amplifier 14.

Title: Monitoring circuit for signal transmission line
Inventor: TANAKA SHOJI
IPC: H04B3/46
Filed: 1989-12-27
Abstract: PURPOSE:To simplify the circuit constitution and to attain the reduction in cost by generating a reference signal and a local oscillation signal from one high frequency oscillator and applying amplitude modulation to the reference signal to monitor a signal transmission line. CONSTITUTION:A high frequency signal generated from a high frequency oscillator 1 is distributed by a distributer 2 into two, the one signal is used for a reference signal for a sender and the other is used for the local oscillation signal for a receiver side, then the two high frequency signals are generated from the high frequency oscillator 1. Thus, only one set of the highly expensive and highly stable high frequency oscillator whose circuit constitution is complicated is enough for the purpose. Moreover, the high frequency signal subjected to amplitude modulation is sent as a reference signal to a signal transmission line S and the reception side uses a high frequency signal the same as the reference signal is mixed at a mixer 5 as the local oscillation signal and the result is demodulated, then only the reference signal is extracted and a band pass filter to eliminate an undesired signal is not required and the circuit constitution is more simplified.

Title: Ta-nb-w superheat resistant material
Inventor: WATANABE SADAYUKI
IPC: C22C27/00
Filed: 1994-12-27
Abstract: PURPOSE: To obtain a heat resistant material having high heat resistance without causing recrystallization at the time of use at an ultrahigh temp. and having excellent workability and weldability by adding specified amts. of Nb and W to Ta being a high m.p. material. CONSTITUTION: An alloy is composed of 20-80% Nb, 1-10% W and the balance essentially Ta. This alloy is preferably used after it is melted with electron beams, cast into an ingot, formed in a required shape by hot working such as rolling or swaging and annealed by heating to 1,200 deg.C vacuum or further subjected to mechanical working, welding, etc., if necessary. Since Ta and Nb form a solid soln. and the heat resistance of the solid soln. is higher than that of Ta alone or Nb alone, the alloy hardly causes rapid coarsening of grains or embrittlement even at the time of use at an ultrahigh temp. of >1.200 deg.C.

Title: Piezoelectric actuator
Inventor: ISHIDA HISANORI
IPC: H02N2/00
Filed: 1989-12-26
Abstract: PURPOSE:To obtain a piezoelectric actuator, which is little in power consumption and is small also in size, by a method wherein a piezoelectric element is pressurized by curved springs to obtain the amount of displacement larger than that in the case of the piezoelectric element single element and at the same time, the drive voltage of the piezoelectric element is suppressed low. CONSTITUTION:A piezoelectric element 2 and a curved spring 3 are pressed into a frame 4 and a spare compressive force is applied to each of them. The rigidity of the frame 4 is higher than those of the element 2 and the spring 3 and the expansion of the frame 4 can be substantially neglected to the displacement of the element 2. On the other hand, the relation between the displacement of the spring 3 and a force shows such characteristics that as the displacement becomes large in the drive extent of the element 2, the increment of the force is reduced to a negative. As a result, the relation between the displaceiment of the element 2 and a force shows such characteristics that as the displacement of the element 2 becomes large, the increment of the force is reduced to a negative. As a force which is acted by the element 2 is reduced, the amount of displacement larger than that in the case of the piezoelectric element single element can be taken out via a rod 1.
