Abstract: PURPOSE: To industrially advantageously obtain the subject compound useful as an intermediate for producing a methoxyalkylpyrazine as an essential component of perfume, by treating a bacterium capable of growing with pyrazine as the sole carbon, nitrogen and energy source with a pyrazine derivative.  
     CONSTITUTION: A bacterium [e.g. Agrobacterium sp. (DSM-No.6136)] which is capable of growing with pyrazine as the sole carbon, nitrogen and energy source and converting a pyrazine derivative of formula I (R 1  is H or a halogen; R 2  and R 3  are each H or a 1-4C alkyl; R 1  to R 3  are not H at the same time) into a pyrazine derivative of formula II is inoculated into a medium containing the pyrazine derivative of formula I (e.g. 3-chloropyrazine) and cultured at pH7 at 30°C. The culture solution is subjected to centrifugation to remove cells. The formed and accumulated product is extracted with ethyl acetate to give the objective compound of formula II (e.g. 3-chloro-2hydroxypyrazine).

Title: Geomagnetism detection type bearing sensor
IPC: G01R33/04
Filed: 1991-11-06
Abstract: PURPOSE:To obtain a geomagnetism detection type bearing sensor which can be improved in detection accuracy and reduced in manufacturing cost. CONSTITUTION:The X-direction component of geomagnetism passes through a first magnetic wire 1a in its axial direction and is interlinked with each coil 2a and 2b of a first coil pair. The component of geomagnetism perpendicular to the X-direction component passes through a second magnetic wire 1b in its axial direction and is interlinked with each coil 2c and 2d of a second coil pair. A first signal processing circuit 3a electrically connected to one coil 2a of the first coil pair in the same direction as that of the X-direction component of geomagnetism and to the other coil 2b in the direction opposite to the component detects the impedance difference between the two coils 2c and 2d having correlation with the X-direction component of geomagnetism. Since both coils 2a and 2b (2c and 2d) constituting each coil pair are wound around the same part as that of each magnetic wire 1a (1b), the impedance fluctuation between both coils 2a and 2b (2c and 2d) is reduced and, as a result, the occurrence of detection errors is reduced.

Title: Current-voltage converter circuit
Inventor: ARAI MASASHI
IPC: H03F3/45
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a current-voltage converter circuit in which a frequency characteristic is improved and the oscillation is prevented. SOLUTION: An output signal of a TR 3 in differential connection to a TR 1 is fed back to the base of the TR 3 via a TR 7 and a feedback resistor 6. When a frequency of an input signal given to the TR 3 is high, the frequency of a signal (b) generated at an emitter of the TR 7 gets higher. Since the input signal frequency is higher than the cut-off frequency of a capacitor 10, the capacitor 10 is conductive. Thus, the TRs 1, 8 are in substantially Darlington connection. Since the current supply capability from a 2nd TR is increased, the charging/discharging time constant of a parasitic capacitance caused at an output terminal OUT is apparently reduced.

Abstract: PURPOSE:To obtain an optical recording medium on which a signal with high quality is written with a low write power, by using a high polymer material of nematic liquid crystal having a negative dielectric anisotropy and cholestric liquid crystal as an optical recording layer. CONSTITUTION:The high polymer material of nematic liquid crystal having a negative dielectric anisotropy and cholestric liquid crystal is used as an optical recording layer 3. That is, the optical recording layer 3 is provided on a glass substrate 1 provided with a transparent electrode 2, and a light absorbing layer 4 and a reflection electrode substrate 5 are provided on this layer 3. The light of a semiconductor laser is condensed on the light absorbing layer 4 to locally heat the optical recording layer 3 and a voltage having a frequency lower than the cut-off frequency is applied to cause dynamic scattering in the position where the viscosity is reduced by heating, thereby writing information. The written part and its nearby part are heated again by irradiation of the semiconductor laser light and an electric field having a frequency higher than the cut-off frequency is applied, thereby erasing information. Thus, it is unnecessary to heat this medium at a temperature higher than the isotropic liquid transition point similarly to a conventional medium, and information is written with irradiation of the semiconductor laser light relatively low in power.
