Title: Detecting device for disconnection of sensor
Inventor: ISHIZAWA HIROAKI
IPC: G01R31/02
Filed: 1982-04-09
Abstract: PURPOSE:To prevent a waste of detection time for the disconnection of a sensor by extending or shortening judgement time for the disconnection according to the level of a wire-breaking detection signal. CONSTITUTION:A comparing resistance R is connected in series to the sensor 1 which has a resistance value varying with temperature and the disconnection of the sensor 1 is detected on the basis of the voltage level at the connection point. In this case, when the resistance of the sensor 1 increases owing to low temperature, it takes a long time to stabilize the voltage V at the connection point, so there is a waste of detection time. For this purpose, the voltage V is inputted to a microcomputer 20 a specific time T later, A/D-converted, and then stored. When the converted value is greater than a specific level, the disconnection is judged and when less, a check on the disconnection is made a time nT later. Thus, the judgement time for the disconnection is extended or shortened, so the waste of detection time is eliminated.

Abstract: PURPOSE:To make a liq. highly separable by pervaporation method and enhance the permeation rate of the separated liq. to a practical level. CONSTITUTION:A specific liq. component is separated from a solution mixture 2 by pervaporation method wherein a vapor of the solution mixture 2 is passed from a solution chamber 3 through a permeable membrane 4 into a pressure reducing chamber 1.

Title: Head switching noise eliminating circuit
Inventor: SAKAI TETSUO
IPC: G11B20/02
Filed: 1986-03-18
Abstract: PURPOSE:To obtain excellent noise eliminating performance by a simple constitution, by sample-holding a demodulating output of a reproducing FM signal by a specific condition, and eliminating a modulated component generated by sampling, from its output signal. CONSTITUTION:A demodulated sound signal which is outputted from a demodulator 18 is applied to a sample holding circuit 31. A sampling signal S8 of this circuit 31 is applied from a multiplying circuit 32. The circuit 32 multiplies an output signal S5 of both the edge trigger circuit 20 and outputs the signal S8 exceeding 40kHz. In this case, the signal S8 is set so that a noise generating period becomes a high level. A signal which has been brought to sampling by the signal S8 becomes a signal S9. The signal S9 does not have a spectrum in a sound signal band generated by the head switching noise. Accordingly, by making the signal S9 pass through an LPF 33 for eliminating the signal component exceeding 20kHz, the modulated component can be eliminated from the signal S9. In this way, the excellent noise eliminating performance is obtained.

Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To make detectable a high quality magneto-optical signal with an inexpensive constitution by making luminous flux from a light source reflect, irradiating a recording surface with it, making the recording surface reflect it, making the luminous flux pass through a polarizing beam splitter incident on a transparent optical element, emitting it, tilting the optical element in a surface containing an optical axis to be the advance direction of the luminous flux and making the incident surface and the emitting surface of the optical element parallel to each other.

In such a case, a magnetic domain 7 is recorded or the magnetic domain 7 on the track 6 is reproduced. Reflection light rotating its polarization plane through a magnetic Kerr effect is made incident on an objective lens again and further, passes through the collimate lens 3 to become convergent light. The convergent light transmits through the platelike polarizing beam splitter 2 according to a polarization reflective characteristic.
