Title: Optical magnetic field sensor
Inventor: NAKAMURA NOBUO
IPC: G01R15/24
Filed: 1990-10-04
Abstract: PURPOSE:To enable magnetic field to be measured highly accurately within a wide temperature range by restricting fluctuation of sensitivity for temperature by detecting difference in quantity of light which is transmitted through two magnetic garnet films with a different film thickness. CONSTITUTION:Light with a wavelength lambda which is divided by a half mirror 21 enters detection parts 40 and 50, is transmitted through magnetic garnet films 42 and 52 whose film thickness is d1 and d2 respectively, is detected by light detectors 6 and 7, difference in quantity of light which is obtained by a subtraction circuit 8 becomes a sensor output I, and is converted to strength of magnetic field. When (GdBi)3 (FeAlGa)5O12 is used for the garnet films 42 and 52, a film thickness d1 set to approximately 90 mum and d2 is set to 195 mum so that change in senser sensitivity for temperature becomes minimum, gain is adjusted so that output ratio of detectors 6 and 7 becomes 3.0, and magnetic field is changed by + or -40Oe within a temperature range of -20 - +60 deg.C, the sensor output I namely change in sensor sensitivity, is kept to be within + or -1.5% and to be flat and further a high sensitivity is achieved, thus enabling magnetic field to be measured with improved accuracy.

Abstract: PURPOSE:To prevent use-up of hot water and to always supply hot water of predetermined temperature with low power cost by dividing a hot water storage unit into a plurality of boilers, connecting them in series, and providing boiling heaters and control sensors in the respective boilers. CONSTITUTION:A hot water storage tank is divided into a plurality of tanks 1 T1, 2 T2 and 3 T3, which are connected in series. When it becomes midnight power time zone energization starting time, a controller 2 starts boiling by a timer 3 T3 by a heater 3 H3, and whether its temperature t3 reaches a set temperature ts or not is detected by a sensor 3 S3. If t3<=TS is satisfied, heating is continued; if t3>=TS, the heater 3 H3 is turned OFF to stop boiling, and the tanks 1, 2 T1, T2 are boiled. If the temperature t3 of the tank 3 T3 is lowered from the set temperature TS by predetermined temperature tm or higher, the boiling of the tanks 1, 2 T1, T2 is stopped, and the tank 3 T3 is boiled. Thus, additional boiling time is shortened to prevent use-up of the hot water, and hot water of set temperature can be always supplied with low power cost.

Title: Magneto-optical recording method
Inventor: HOSHINA SHOJI
IPC: G11B11/10
Filed: 1990-10-05
Abstract: PURPOSE:To suppress an expansion of magnetic domain width and to decrease cross talk by changing the number of irradiation pulses according to the length of an inversion magnetic domain to be recorded. CONSTITUTION:The number of pulses is changed in accordance with the length of an inversion magnetic domain. In this case, irradiating energy per unit length is decreased in accordance with increasing of the inversion magnetic domain length, and an accumulation of heat is prevented, and the inversion magnetic domain width can be diminished. Then, because of a continuous short-pulse train, a temp. distribution sloping gently in the track direction and steeply in the orthogonal direction to the track is conjectured. Moreover, it is presumed that the inversion magnetic domain is hardly formed in the orthogonal direction to the track owing to contractive force of a magnetic wall on account of a temp. gradient, so that the inversion magnetic domain width can be diminished, while the inversion magnetic domain length can be controlled by the number of pulses. By this method, increasing of the inversion magnetic domain width is suppressed, and hence cross talk can be suppressed.

IPC: G01F1/688
Filed: 1991-09-20
Abstract: PURPOSE:To obtain a thermal flowmeter which can prevent the excessive rise of temperatures even when a flow rate is small. CONSTITUTION:A first cooling mechanism 9 is provided at the upper side of the stream than a first upstream temperature sensor 4 for a pipe 1, and a second cooling mechanism 10 is placed at the lower side of the stream than a first downstream temperature sensor 5.
