Title: Water level detector of machinery
Inventor: MOCHIDA NORIHITO
IPC: G01F23/22
Filed: 1987-03-20
Abstract: PURPOSE:To obtain a liquid level detector not having a contact and a movable part and stabilized in operation, by constituting the same so that the presence of the arrival of a water level is detected by the liquid level detection part mounted in a water tank to be outputted as impedance data. CONSTITUTION:When frequencies from fstart to fstop are continuously generated from a frequency generating part 5 and swept to a liquid level detection part 3 to be applied thereto, since a resistor 4 and a liquid level detection part 2 are connected in series in a liquid level detection part 3, if the voltage level of frequency to be applied is made constant, the output voltage of the liquid level detection part 3 changes corresponding to the impedance change of the liquid level detection part 2. This output voltage is smoothed by a smoothing circuit 7 and amplified by an amplifying part 8 and subsequently compared with reference voltage by a voltage comparing part 9 to output a high level signal. By this constitution, only by sweeping frequency having a proper band to apply the same to the piezoelectric type liquid level detection part 2 from the frequency generating part 5, the presence of the arrival to a predetermined water level can be detected on the basis of the signals of 0 and 1 from a liquid level judge part 6 and a detector not having a contact and a movable part and stabilized in operation is obtained.

Title: Image audio information distribution system
Inventor: IKUSHIMA MAKOTO
IPC: H04N7/173
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To operate a system continuously by suppressing the effect of a fault to a minimum even when the fault occurs in an output port. SOLUTION: An image audio distribution device 100 is provided with a storage means that stores image audio information and plural output ports which reads the image audio information from the storage means and distributes them via a two-directional transmission line 120.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a device which does not increase the circuit scale in spite of the increase of the required arithmetic quantity per a unit output pixels and can freely change an arithmetic coefficient by operating and controlling a multiplier and an adder at a frequency higher than that for outputting data of one pixel. SOLUTION: A data storing means 4 for storing video data, a sub-video, an arithmetic coefficient and a multiplication/addition result is provided and a data selecting means 5 reads an arithmetic processing result obtained by multiplication and addition in advance from the means 4 to execute next arithmetic processing with respect to the data.

Abstract: PURPOSE:To suppress an electric current which flows at a recording electrode and to significantly enhance life by forming uniformly a depletion layer at the whole surface of a semiconductor substrate beforehand and impressing the polarity of many carriers and the voltage having the same polarity in the semiconductor substrate as a recording signal voltage. CONSTITUTION:When the signal is recorded to a recording media 1, a recording electrode 10 thinly fitted to the side surface of a needle-shaped electrode supporting body 9 composed of sapphire and other dielectric is allowed to contact with the recording media 1 and for example, by rotating the recording media 1 both are relatively shifted. At the area where a recording signal voltage 14 is impressed, the depletion layer 6 in the semiconductor substrate 3 is extended in the thickness direction. Due to the voltage applied to the extended depletion layer, at the surface part of the semiconductor substrate 3, an avalanchebreakdown or a tunnel effect, or both occur. An electron which is a small number of carriers, is accumulated at the surface area and the inverting layer is formed. The electron of the inverting layer passes through the first insulating film 4 by the tunnel effect, is trapped and accumulated in the second insulating film 5 and the signal is recorded in the shape of an accumulating charge 8 in the second insulating film 5.

Title: Fm reproduction unit
Inventor: SATOU TERUO
IPC: H03G11/06
Filed: 1979-05-30
Abstract: PURPOSE:To improve the distortion of reproduced signal due to phase modulation of a limiter circuit, by applying the output signal of an intermediate frequency signal passing filter to the limiter circuit via a level correcting circuit. CONSTITUTION:The output signal of an intermediate frequency signal passing filter 2 is fed to an amplitude modulating circuit 5, the output signal of the filter 2 is fed to a negative amplitude detecting circuit 7 via a variable gain amplifying circuit 6, and the AC component obtained at the output side of the circuit 7 is fed to the input terminal of modulation signal in the circuit 5. Further, the DC component obtained at the output side of the circuit 7 is fed to the control terminal of the circuit 6 via an automatic gain control circuit 8. Thus, the detection output signal independently of the input signal level as the AC component of the output signal of the circuit 7 can be obtained and the output signal of the filter 2 is inversely modulated with this signal. Accordingly, the amplitude modulation level at the circuit 5 can be made shallow remarkably. Since the output signal of the circuit 5 is fed to the limiter circuit 5, the phase modulation component in the circuit 3 can be made less.
