Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To enable easy manufacture and assembly and improve preventive effect of cogging phenomenon, by providing a portion which varies in thickness in the radial direction in the circumferential direction. SOLUTION: A cylindrical magnet 1c is an integral magnet. The inner diameter of the magnet 1c is constant while the outer diameter is reduced at parts formed at intervals of about 90 deg.. At these four parts, thinner portions (thickness varied portions) 4 with reduced thickness (in the direction of diameter) of the magnet are formed. These four thinner portions 4 are formed at angular regular intervals. The position of each of the thinner portions 4 in the circumferential direction of the cylindrical magnet 1c continuously changes in the axial direction of the cylindrical magnet 1c. That is, the thinner portions 4 are formed with a predetermined inclination with respect to the axis 6 of the cylindrical magnet 1c.

Title: Variable strobe light diffusing plate device and electronic equipment using the same
Inventor: CHINO EIJI
IPC: G02F1/1333
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To instantaneously execute strobe light irradiation suitable for a subject within an image plane by performing driving control selected in accordance with photographing circumferences and changing the diffused state of strobe light within the image plane. SOLUTION: Since liquid crystal 13 and macromolecule 14 are oriented in the same direction by the effect of an oriented film 19 in a state where voltage is not impressed on a liquid crystal layer 15 where the liquid crystals 13 and the macromolecules 14 are mutually oriented and dispersed, a refractive does not differ between the liquid crystal molecules and the macromolecules, and light is transmitted. As the liquid crystal 13 is oriented in an electric field direction with the impressing of the voltage, the refractive index differs between the liquid crystal molecules and the macromolecules, and the light is diffused.  In the case a subject exists proximately, a driving control part 18 selects so that the voltage may be impressed only on a part in that direction, thereby, the overexposure of the proximate subject is prevented and a background is irradiated with the sufficient quantity of light.

Title: Image decoder
Inventor: KURIHARA KOICHI
IPC: H03M7/30
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To attain display offset processing including line number conversion processing without increasing the memory capacity. SOLUTION: A synchronizing signal generating circuit 22 generates a correction synchronizing signal delaying a synchronizing signal based on a display vertical offset and line number conversion processing. A memory write control circuit 17 writes data based on a synchronizing signal on time basis to a frame memory 6. A memory read control circuit 21 reads the data based on a corrected synchronizing signal on time basis from the frame memory 6. Since the corrected synchronizing signal is delayed more than the synchronizing signal, even when a read rate is higher than a write rate, precedence of read over write is prevented. Thus, display offset processing including line number conversion processing is attained without increasing the memory capacity.

Title: Humidity sensor circuit
Inventor: SASAKI NOBUTOSHI
IPC: G01N27/12
Filed: 1984-08-31
Abstract: PURPOSE:To measure humidity stably with high precision by connecting such a parallel resistance that the square of its coefficient of correlation to an approximation line of variation in electric resistance with humidity is 0.980-1.000 in parallel. CONSTITUTION:The sensor circuit constituted by connecting the parallel resistance 2 to a ceramic humidity sensor 1 in parallel is used to approximate humidity values at 3-4 points linearly and the square of the coefficient of correlation obtained at this time is represented as the value of the parallel resistance. Then the parallel resistance has the most linear variation in electric resistance with humidity. When the square of the correlation coefficient is <=0.980, the linear relation is deficient and it is difficult to take a high-precision measurement, so this is not practical. When the coefficient is 0.980-1.000, the variation in resistance value with humidity is changed into a proportional relation only by connecting the parallel resistance whose square of coefficient is 0.98-1.000 in parallel, so that the humidity is measured easily with high precision.
