Title: Color image processing unit
Inventor: UNNO YASUNAO
IPC: H04N1/21
Filed: 1995-03-14
Abstract: PURPOSE: To reduce the memory capacity by reducing the gradation of each of color expression data components of image data prior to compression processing or not reducing it so as to compress the image data without remarkable deterioration in the gradation characteristic in a visual sense. CONSTITUTION: Color image data read from a memory 200 are given to a gradation reduction section 330, in which gradation reduction is processed independently as to each color component. The gradation is reduced by 2-bit for a Y component with low recognition characteristic as 2<6> gradation, by 1-bit for a K component as 2<7> gradation, and no reduction for a component as 2<8> gradation. The image data whose gradation is reduced are given to a DCT 310, in which discrete cosine transformation is executed and a transformation coefficient is generated. A quantization processing section 315 applies quantization to the data by using a quantization table selected among a quantization table group 31 through the use of the transformation coefficient.  The quantization table is selected for each color component based on the result of discrimination by a data discrimination section 312 and the reduction information from the gradation reduction section 330. Furthermore, the data after decoding are expanded by gradation decoding processing at the final stage.

Title: Magnetic field sensor
Inventor: TOYODA KAZUMI
IPC: H01L43/00
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To prevent an abrupt change against a temperature change and to accurately detect the external magnetic field by connecting an amorphous magnetic body between electrodes of an insulating substrate with a sag. SOLUTION: A magnetic field detecting element connected between electrodes 2 and 2, e.g. an amorphous wire, 3 is connected by welding between a wire and respective electrodes 2 with a sag 4. The sag 4 is a magnitude capable of giving a slack to the wire 3 not to generate tensile stress in the region from -30 deg.C to 80 deg.C, for example. An inductance change against a temperature change can be nearly unified in the whole region of the temperature range, the occurrence of an abrupt change point of inductance can be excluded, and the external magnetic field can be accurately detected. When an abrupt change occurs, the sensor output is changed to cause an error, however the external magnetic field can be detected with no detection error by this magnetic field sensor.  The external magnetic field quantity passing in the axial direction of the magnetic field detecting element 3 is changed according to the shape and direction of the deflection of the magnetic field detecting element 3 to affect the sensor output, thus the shape of the deflection is desirably made uniform.

Abstract: PURPOSE:To reduce a starting current by controlling fan motor driving means to manage a start and a stop, and thereby sequentially raising to a required tap. CONSTITUTION:When a drive switch 4a of operation display means 4 is closed to request a drive, control means 3 judges a starting time and turns ON a drive element 2a for driving a tap 1b for a weak notching drive having a small starting current. After starting, if a stop is requested, i.e., if the switch 4a is opened, the elements 2a, 2b are turned OFF to stop it. If it remains in a state that the drive is requested, a time after starting is monitored, and whether an arbitrary time is elapsed or not is decided. If it is elapsed, the elements 2a, 2b are controlled in response to a drive request by a flow rate changeover switch 4b. If the arbitrary time is not elapsed, the weak notching drive by the element 2b is continued. Thus, the starting current can be reduced.
