Title: Drive device for motor
Inventor: SAITO MASAAKI
IPC: H02M7/48
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent demagnetization at low temperature of a magnet in a permanent magnet-type brushless motor. SOLUTION: A thermistor TM is installed at an inverter IV. The temperature of switching elements S1 to S6, which are nearly proportional to the temperature of a permanent magnet-type three-phase DC brushless motor M, are detected. The detected temperatures are input to a control part CO. Whether the switching elements S1 to S6 are at a prescribed temperature or lever, generating the demagnetization at a low temperature of a magnet is determined by the control part CO. A resistance R4, whose resistance value is higher than that of a resistance R1 and that of a resistance R2, is installed. Both its ends are connected to the connecting point of the two voltage-dividing resistances R1, R2 and to the changeover signal output terminal PO of the control part CO.  When a temperature which is a detected by the thermistor TM is at the prescribed temperature or lower, a changeover signal at a level L is output from the changeover-signal output terminal PO of the control part CO, and a reference value to the inversion input terminal of a computer CP is changed over to be low, as compared to the case in which the detected temperature is higher than the prescribed temperature.

Title: Optical fiber coupler and making thereof
Inventor: JIYON JIEI FURINGU
IPC: G02B6/28
Filed: 1986-12-29
Abstract: A fiber optic coupler (20) is formed by heating juxtaposed optically flat surfaces (34,36) formed on two lengths of optical fiber (22,24) to the glass transition temperature. The fibers bond together while preserving the molecular composition of the fibers at bonded region. Depending upon the depth to which the fibers are lapped to form the optically flat surfaces, the coupler may be either an evanescent field coupler or a core intercept coupler. The fibers may be mounted on curved substrates and then lapped to form the optically flat surfaces. The optical throughput of a fiber may be monitored during assembly of a coupler to permit adjustment of the positions of the optically flat surfaces to produce a desired coupling efficiency. The fibers may then be bonded together by application of energy from a suitable coherent light source such as a CO₂ laser.

Inventor: KURIYAMA KENICHI
IPC: C07D493/04
Filed: 1993-11-22
Abstract: PURPOSE:To easily obtain a large quantity of lignan glycosides by humidifying or culturing sesame seeds to effect germination and converting the germinated seeds into a ground product or defatted lees, which is then extracted with a hydrous alcohol. CONSTITUTION:Unparched or unheated sesame seeds as raw material are humidified or cultured to effect germination and increase the lignan glycoside in the seeds; the germinated seeds are converted into a ground product or defatted lees, which is then put to extraction with a hydrous alcohol (e.g. hydrous methanol) to obtain the objective lignan glycosides which are water-soluble glycoside lignans consisting mainly of di- and/or triglycoside lignans with two or three molecules of glucose linked to one another. Oil-soluble lignans consisting mainly of sesaminol can be obtained by acting an enzyme (e.g. beta-glucosidase) having lignan glycoside-hydrolyzing activity prepared from sesame seeds on the hydrous alcohol extract.

Abstract: PURPOSE:To dry wet clothes uniformly in a short time by arranging a planar far infrared heater on the wall surface of a dry box and by enabling the angular change of a fan in the directions of both clothing hanger and planar far infrared heater. CONSTITUTION:First, a fan 7 is directed in the direction of a planar far infrared heater 5 to send air to raise the temperature within a dry box 1.

Then, when wet clothes are suspended with a clothing hanger 3 and the direction of the fan 7 is changed to that of the clothing hanger 3, warm air is hit against the suspended clothes from below to dry the clothes. Thus, it is possible to conduct drying efficiently.

Thus it is possible to automatically decide a scale and the plotting position of each diagram to plot a polyhedral diagram on a display screen in its full size. Thus a polyhedral diagram is plotted.

Title: Current summing type digital/analog converter
Inventor: KANAMORI KOJI
IPC: H03M1/00
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To realize a current summing type digital/analog converter with the reduced power consumption. SOLUTION: The current summing type digital/analog converter is provided with a control terminal 17, the resistance of a resistor 10 deciding a reference current of a current mirror is doubled by applying a control signal to the terminal 17 to halve an operating current of a current cell matrix 1. On the other hand, the resistance of a current/voltage conversion resistor 16 is doubled to compensate for the decrease in the current and to maintain a digital/analog conversion output. Since an input in the vicinity of a full range does not usually occur, no problem is caused in the operating speed even when the current is decreased.

Title: Method for correcting radiation thermometer and light measuring equipment by utilizing new interpolation formula
Inventor: JIYAEEUON HAAN
IPC: G01J1/00
Filed: 1994-12-20
Abstract: PURPOSE: To reduce the errors by correcting a radiation thermometer and an optical measuring instrument by using a specific formula comprising the product of an exponential function and a polynomial of the reciprocal of the temperature. CONSTITUTION: According to the reference wavelength method, the correction value R(T) is expressed by Eq. I for a black body light source, where L(λr .T) represents the spectral radiation amount emitted from a black body furnace at temp. T with the reference wavelength λr , S(λ) the spectral sensitivity of the radiation thermometer, and V(T) the signal of radiation thermometer at temp. T. Equation III is derived by expressing the correction value R(T) in the form of a quadratic polynomial of the reciprocal of the temperature, turning a, b, c into a composite factor, applying Planck's radiation law to L (λ.T), introducing the number K defined by Eq. II, and substituting to K0 at a specific temp. T0 to give R(T)=1, where C1 and C2 are the first and the second radiation constants. The factors a, b, c in Eq.  III can be determined from values corrected at three points or more, and the temp. of the radiation thermometer can be calculated by the repetition method. By this interpolating formula, the temp. error can be minimized over a wide temperature range and with effective wavelength.
