Patent JP-S58146859-A (JP)
Title: Optical current and magnetic field measuring device
Inventor: HISAMA KAZUO
IPC: G01R15/24
Filed: 1982-02-24
Abstract: PURPOSE:To measure an optical current and a magnetic field with high sensitivity, by using an oxide crystal whose Verdet constant is large, as an optical Faraday element. CONSTITUTION:Light emitted from an optical transmitter 1 is led to an optical sensor 3 through an optical fiber 2. When the light is converted to a parallel beam by a microlens 4 and is propagated in an optical Faraday element 9 consisting of an oxide crystal, if a magnetic field is applied in the advancing direction of the light, the polarized face of the light is Faraday-rotated. As for the oxide crystal, its Verdet constant being a performance index of a Faraday effect is large, comparing with lead glass, therefore, when it is used, the current and magnetic field detecting sensitivity can be improved. Also, a crystal belonging to a cubic system does not show natural double refraction essentially, therefore, its temperature characteristic is also good. In this way, by using an oxide crystal whose Verdet constant is large, as the optical Faraday element, an optical current and a magnetic field can be measured with high sensitivity.

Patent JP-S63196916-A (JP)
Title: Temperature stabilizing circuit
Inventor: SATO YUKINORI
IPC: G05D23/24
Filed: 1987-02-10
Abstract: PURPOSE:To easily and inexpensively stabilize the temperature by supplying a current to a fan through a thermistor and setting the thermistor in a place where the temperature should be stabilized. CONSTITUTION:A thermistor 1 is connected between a fan 2 and a power source 3 and is set near a heat generating part 4. When the temperature of the heat generating part 4 is low, the current of the fan 2 is reduced and the air quantity of the fan 2 is reduced because the thermistor 1 has a high resistance. When the temperature of the heat generating part 4 is high, the fan driving current is increased and the air quantity of the fan 2 is increased because the thermistor 1 has a low resistance. Consequently, the temperature of the heat generating part 4 is stabilized. Thus, the fan driving current is supplied through the thermistor to easily and inexpensively stabilize the temperature.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To effectively retrieve the stored image information by producing a reduced image in addition to its original photographed one to store them in a set of N sheets and then reading these images out of a storage medium in a set of N sheets as necessary. SOLUTION: The photographed still pictures are reduced in a set of N sheets in a DSVC(digital still video camera) as the index display units of new images and then stored in a memory card 5. In a retrieval mode, a CPU 27 performs the control to display the images stored in every display index on an LCD 33. In this form of execution, an index image consisting of N sheets of reduced images is stored on an original image. As a result, N sheets of images can be retrieved at a time and the retrieval efficiency is improved. As the index images are held on the original image, the images can be retrieved via the DSVC with no intervention of a personal computer. Thus, the retrieval time of the stored image information can be shortened.
