Patent JP-S57147103-A (JP)
Title: Magnetic recording and reproducing system
Inventor: SAWAZAKI KENICHI
IPC: G11B5/02
Filed: 1981-03-04
Abstract: PURPOSE:To obtain practically sufficient S/N at reproduction even in the <= specified mum width of recording track, by providing a high-frequency resonance circuit which achieves low noise and high sensitivity. CONSTITUTION:When a magnetic field DELTAH corresponding to recorded information on a recording medium 10 changes a permeability mu of a magnetic substance 11, an inductance L of a resonance circuit 12 is changed and the resonance frequency of the circuit 12 is changed. When the resonance frequency is changed, an output of a high-frequency oscillator 13 is subjected to amplitude modulation, and a recording signal component is picked up by detecting this amplitude-modulated-signal with a detection circuit 14. In this reproducing system, since the head amplifier noise can be made to very lower values, the recording and reproduction at a narrow track width can be made, allowing to achieve ultra-high density magnetic recording and reproduction.

Title: Infrared detector
Inventor: FUMOTO TAKAFUMI
IPC: G01J1/02
Filed: 1984-02-20
Abstract: PURPOSE:To make the titled detector usable also to an infrared analyzing instrument for on-line by setting an infrared absorption material in a tightly closed vessel, sealing a gas having no infrared absorption characteristics, and detecting the pressure variation of the sealed gas caused by the incident infrared ray. CONSTITUTION:The infrared ray 8 made incident from an infrared transmitting window 5 is absorbed by the infrared absorbing material 6, converted to thermal energy, thereby, the gas in a detecting chamber 2 is expanded thermally and the pressure is raised. On the other hand, the pressure is not varied in a standard chamber 3 since infrared ray is not irradiated therein. Accordingly, the sealed gas flows through a connecting path 4 due to the pressure difference between the chambers 2 and 3. If the ray 8 to be detected is irradiated intermittently, the sealed gas is vibrated between the chambers 2 and 3. Consequently, the vibration is converted to an electric signal by a heat ray element 7 arranged at the path 4, and the intensity of the ray 8 is detected from the electric signal.

Title: Composite type ptc thermistor device
Inventor: TOSAKA HISANAO
IPC: H01C7/02
Filed: 1993-02-19
Abstract: PURPOSE:To enhance thermal; conductivity between a heating PTC thermistor and a common terminal and between a current control PTC thermistor and a common terminal by reducing the difference between projected and recessed parts on an electrode layer of PTC thermistor. CONSTITUTION:A metal layer 2, such as Ni-made layer is formed on both surfaces of a PTC thermistor element and an electrode layer is further formed with a metal layer 3 made of Ag or the like based on a screen print method. This metal layer 3 is produced by removing a certain amount of portion from an original metal layer 4 by plane polishing. The surface of the PTC thermistor element is plane-polished so that the difference between the projected and recessed parts on the surface may be reduced to 10mum and below. This construction makes it possible to raise the efficiency of thermal conductivity of a heating PTC thermistor and a current control PTC thermistor and increase balanced resistance of the current control PTC thermistor element and minimize balanced point current. It is, therefore, possible to reduce the balanced point current and power consumption during operation.

Filed: 1992-01-21
Abstract: PURPOSE:To enable efficient and continuous obtaining of a plant tissue by removing noxious substances from a culture solution containing the substances noxious for the growth of a callus by separation with a membrane. CONSTITUTION:A leaf of a plant body such as Acanthopanax senticosus Harms is cultured in an agar culture medium to provide a callus, which is then transplanted to a liquid culture medium such as Gamborg's culture medium and cultured to provide a browned culture solution containing noxious substances. The resultant culture solution is subsequently brought into contact with a separation membrane, usable under a relatively low pressure (1-5atm) and capable of performing separation with a difference in molecular weight and utilizing charging properties such as a reverse osmosis membrane at ambient temperature and filtered through the membrane to afford a permeated liquid free of the noxious substances. The obtained permeated liquid is then added to a usual culture solution to carry out culture of a plant tissue. The treatment with the membrane, as necessary, is continuously performed in a culturing process.
