Title: Circuit board
Inventor: AKASAKA TAKASHI
IPC: H05K1/00
Filed: 1993-12-30
Abstract: PURPOSE:To prevent a board from being warped and to increase the degree of freedom in wiring direction of a signal line with equal transmission characteristics by forming and arranging a hexagonal or circular opening on a power supply layer or a ground layer and then wiring the signal line along the arrangement direction of an opening. CONSTITUTION:A plurality of hexagonal openings 13A are arranged and formed on a ground layer 13 and signal lines 14, 15, and 16 are wired in a direction for connection each center of each opening 13A along the arrangement direction of each opening 13A. As a result, when the temperature of a circuit substrate 11 changes, a stress is generated to cause warpage in a circuit substrate 11 due to the difference in the thermal coefficient of expansion of copper foil and the base of the circuit substrate 11 forming the ground layer 13 but the stress is scattered without being centered in a fixed direction since the opening 13A of the ground layer 13 is formed in hexagonal shape. Also, when the area of the metal foil of the ground layer 13 opposing the signal lines 14-16 is made equal to match the transmission characteristics of the signal lines 14-16, the wiring direction becomes the direction 3 for connecting the center of each opening 13A.

CONSTITUTION:A suspension device 27 consisting of a hydraulic cylinder 28, an accumulator 31 and a throttle valve 33, and a stroke sensor 37 for detecting vertical displacement is provided between a chassis 22 and each wheel 25. The detection signal from the sensor 37 is divided into displacements of frequency components higher and lower than a determined frequency by a controller 38. The displacement of the higher component is dumped by the throttle valve 33 of each suspension device 27, and a control valve 35 is controlled on the basis of the deviation obtained by relatively operating the displacement with the lower component with a target value signal followed by calculation to supply and discharge oil liquid to the oil chamber A of the hydraulic cylinder 28 to actively (forcedly) damp the vibration. Thus, a fine vibration at traveling is damped by the throttle valve 33, and a large vibration at turning is damped by the oil liquid supplied to and discharged from the hydraulic cylinder 28.

Title: Motor controller
Inventor: TAKANO TOSHIO
IPC: H02P6/08
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To attain a motor controller, capable of rotating a motor with high efficiency by reducing rise in reactive current and drop in torque. SOLUTION: A CPU captures a torque command iq*(S10), a current value iu of a u-phase and the current value iv of a v-phase (S12), and a rotational angle θ(S14). It computes an average angular velocity εθ (n-1) between the detection points (S16) and a rotational angle at current detection timing, i.e. a rotational angle θ01 (n-1) used in d/q conversion (S18). Therefore, a timing lag between current detection and rotational angle detection is corrected enabling d/q conversion. Then, a rotational angle at the next detection timing, i.e. a rotational angle θ2 (n) used for d/q conversion is computed (S20). As a result, a d/q converting part 56 can output a voltage command converted into three phases, in synchronization with the next rotational angle detection timing.

Abstract: PURPOSE:To make the level of video signals obtained by high-speed shutter speed photographing and normal shutter speed photographing almost equal at all times regardless of the fluctuation of the characteristics of an AGC. CONSTITUTION:The photographing at a high-speed shutter speed once in 18 fields and at a normal shutter speed at other times is cyclically repeated. For luminance signals for indicating adjacent pictures, the luminance signals for one field obtained by the photographing at the high-speed shutter speed are integrated at a first integration circuit 21 and the luminance signals for one field obtained by the photographing at the normal shutter speed are integrated at a second integration circuit 22. The difference data of integrated values are calculated by a difference detection circuit 23 and supplied to the AGC 6 as gain correction signals. At the AGC 6, gain control signals are corrected by the gain correction signals and the level of the video signals at the high-speed shutter speed and the level of the video signals at the normal shutter speed are made almost equal.

Abstract: PROBLEM TO BE SOLVED: To ensure a sufficient strength even when a strap is stretched by forming upper and lower covers integrally such that a space for fixing the strap is created at the boss fitting part when the upper and lower covers are fitted. SOLUTION: Upper lower covers 3, 4 are formed of a plastic material and a boss 8 is integrated such that both covers can be fitted by means of a screw 9 and the case for a hand held terminal is constructed of the upper and lower covers 3, 4. A slit-like strap fixing space 7 is formed around the boss 8. The screw 9 being driven into the boss 9 in order to joint the covers has higher strength than resin because it is made of metal. Consequently, a strap fixing mechanism is protected against damage even if the strap is pulled strongly.

Title: Image signal coding method, image signal coder, image signal transmission method and recording medium
Inventor: KONDO TETSUJIRO
IPC: H04N19/80
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration in image quality by inverting at random the polarity of a quantization error as to adjacent picture element data, thereby efficiently improving the compression. SOLUTION: Two kinds of re-quantization data (re-quantization data quantized to have a positive error and re-quantization data quantized to have a negative error) are fed to selectors 254-256 from quantization circuits 247-249 in each hierarchical layer. Then the re-quantization data quantized to have a positive error or re-quantization data quantized to have a negative error are selected alternately and outputted according to a clock signal from a controller 257. As a result, block distortion caused when all picture elements in a block have a quantization error in one polarity is avoided and deterioration in the image quality on a visual characteristic is suppressed.
