Title: Optical disk recording and reproducing device
Inventor: DOI HIDEKI
IPC: G11B7/09
Filed: 1987-08-20
Abstract: PURPOSE:To stably perform tracking control at the time of recording, by providing a first gain control means and a second gain control means which change the levels of the detecting signals of two sub laser beams detected by a three- beam method. CONSTITUTION:The two sub laser beams reflected on an optical disk are detected by the photodetectors 3a and 3b of an optical detector 3 of sexenary split, and a signal obtained at a first detection amplifier circuit 10 is inputted to the first gain control means 12, and the signal obtained at a second detection amplifier circuit 11 is inputted to the second gain control means 13. Those first and second gain control means 12 and 13 change the gains of input signals by the ratios of resistors 12a and 13a, and variable resistors 12b and 13b, respectively, when switching means 12c and 13c are turned ON by a control signal from a CPU that is the control part of an optical disk recording and reproducing device. In such a way, it is possible to set the levels of two detecting signals at the same level in a recording and a reproducing operations, thereby, stable tracking control can be obtained.

Title: Method for reforming water
Inventor: SAWADA TOMOKO
IPC: C02F1/30
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To provide novel treatment to change the properties of water quality quite different from the conventional water purification using distillation or ion-exchange resin, electrolysis, etc., by maintaining a ceramic having far IR radioactivity in the water. SOLUTION: A ceramic having far IR radioactivity is maintained in water to reform the water. Any ceramic exhibiting radioactivity in 6-15μm wavelength range can be used as the ceramic. Although the powdery ceramic is used as such, the one, which has been solidified into column, prism, sphere, etc., in calcination, is preferably used. The reformation of water is confirmed about one week after the ceramic is added directly to the water, however the water is reformed in a short time by adding the ceramic and then heating or boiling the water.

Abstract: PURPOSE: To provide an image forming device which is always highly accurate and firm in strength even in any condition and to drastically reduce developing man-hour. CONSTITUTION: An analog signal after detecting the set voltage of an electrifier and the surface potential of a photoreceptor is converted into a digital signal with an A/D converter 102 and arithmetically processed by a neural network.

Title: Surface acoustic wave element
Inventor: MORII HARUO
IPC: H03H9/145
Filed: 1990-08-03
Abstract: PURPOSE:To prevent the increase of a built-in space and the number of input/ output terminals and to realize cost reduction by forming resonators for low and high frequencies along the propagation direction of a surface acoustic wave on a piezoelectric substrate in parallel and housing them in a single package with four-terminal construction, as it is. CONSTITUTION:A resonator corresponding to two frequencies different from each other, that is, a resonator 2 for low frequency and a resonator 3 for high frequency are integrated while in the state of parallel arrangement, and stored in the single package with the four-terminal construction, as it is. Then, when a signal is inputted between an input terminal electrode 7 and an earth terminal electrode 9, the low frequency output can be obtained from between an output terminal electrode 8 and the earth terminal electrode 9. On the other hand, the high frequency output can be obtained from between the output terminal electrode 8 for high frequency on a resonator 3 side and the earth terminal electrode 9. Thus, the inexpensively constructed surface acoustic wave element can be obtained without increasing the built-in space and the number of input/ output terminals.

Title: Liquid transferring device
Inventor: MASUDA MASASHI
IPC: F17D1/14
Filed: 1990-08-07
Abstract: PURPOSE:To greatly reduce troublesomeness in maintenance and supervising by placing a suction tank in a position higher than that of a receiving tank, and by providing a depressurizing device which depressurizes the inside of the suction tank for sucking of liquid in a liquid storage tank up to the suction tank. CONSTITUTION:With a vacuum pump 5 started with a three-way valve 11 driven and a depressurizing pipe 10 communicated with the vacuum pump 5, liquid 3 in a liquid storage tank 1 is sucked up through a suction pipe 6 as the pressure inside a suction tank 4 decreases, and is stored in the suction tank 4. At this time, the liquid inside a trap pipe 8 is sucked, flowing backward, toward the suction tank 4. However, continuous reverse flow of the liquid from a receiving tank 2 to the suction tank 4 does not occur because the height H3 of the trap pipe 8 is bigger than the range of lift H1 of the suction pipe 6, and balance is attained when liquid head pressure is produced in accordance with the degree of depressurization inside the suction tank 4. As the inside of the trap pipe 8 is sufficiently filled with the liquid stored in a lower tank 9, water seal in the trap pipe 8 is kept without the fear of becoming defective.

Filed: 1988-08-24
Abstract: PURPOSE:To enable execution of quick and precise measurement by disposing in the same case a pair of transversal-wave vibrators which are made adjacent on the same plane, made to intersect each other perpendicularly in the direction of vibration and employed for both transmission and reception. CONSTITUTION:When a substance 10 to be inspected is measured by a probe, the probe is brought into contact with the substance through the intermediary of a contact medium so that the probe is across a line y-y of the substance 10 whereon a round hole 10a is provided therein. When a stress sigma1 acts on the substance 10 in the direction X herein, stress concentration occurs at the edge of the round hole 10a and the stress on the line y-y is not fixed. When a transversal wave is made incident in the direction of the plate thickness of the substance 10 from each transversal-wave vibrator at each measuring position, a reflected wave from the base of the substance 10 is received and sonic speeds in the respective directions of vibration in the directions X and Y are measured simultaneously. The measured sonic speeds are compared with a known reference sonic speed on the basis of the principle of a double refraction effect of a transversal ultrasonic wave that a sonic speed difference between two transversal waves is proportional to a stress difference, and a stress at the given measuring position is determined from the stress difference.
