Title: White peak clip circuit
Inventor: KONDO SATORU
IPC: H04N5/20
Filed: 1992-06-22
Abstract: PURPOSE:To suppress a white peak without causing a defect such as brightness change by compressing only a signal for a portion to be a clip level or below when a white peak of a video signal is a reference clip level or over in a video processing circuit for a television receiver or the like. CONSTITUTION:A video signal 21 is given to a clamp circuit 1, in which DC recovery is implemented and the result is inputted to a white peak detection circuit 2 or the like. The white peak detection circuit 2 detects a white peak in a signal and its white peak is compared with a reference clip level 22 by a limiter 3. As a result, when the white peak is the reference clip level or over, the level is outputted and when the white peak is less than the reference clip level, the reference clip level is outputted. With respect to the white peak over the reference clip level, only the portion is compressed while decreasing a multiple factor of a multiplier 9. The multiple factor is obtained through negative addition of the result of arithmetic operation by a comparison arithmetic operation circuit 5 (control correction signal 23) in response to the white peak and a reference control signal 26 at an adder 8. A comparator 6 turns on a switch circuit 7 at a compression start timing.

Title: Ultrasonic vibration body
Inventor: KATAOKA TATSUO
IPC: B08B3/12
Filed: 1994-06-22
Abstract: PURPOSE:To uniformize the distribution of vibration displacement of a radiation plate by bonding plural ultrasonic vibrators whose each radiation surface has the shape of a quadrangle with relatively short sides and whose each resonance frequency is within a limited range to the radiation plate closely to each other. CONSTITUTION:The ultrasonic radiation surface of each ultrasonic vibrator 2 is formed in a square shape with sides of <=50mm by using a radiation plate 1 made of SUS316 and being 432mm wide, 322mm deep and 3mm thickness. The ultrasonic vibrator 2 uses 18-45kHz resonance frequency. Space between the respective ultrasonic vibrators 2 is within zero to a quarter of the wavelength of a transverse wave excited in the material of the radiation plate 1, and the ultrasonic vibrators 2 are arranged at regular intervals. (For example, the ultrasonic vibrators 2 are bonded to the radiation plate 1 in 7-row/4-row, and electrically connected in parallel.) In this way, since the displacement is uniformly distributed and the phase difference is almost eliminated, the stress concentration is not generated to effectively improve erosion resistance.

Title: Column selection processor
Inventor: KIRIGATANI NOBUKAZU
IPC: G06F17/30
Filed: 1989-06-26
Abstract: PURPOSE:To process data with high efficiency and to improve the processing efficiency and speed for selection of columns in particular by disusing the user data and deciding the length of the actual user data when the selection of the user data is rejected. CONSTITUTION:When the data on the corresponding item is rejected by a data selection processing part 5, the data stored in a counter 5-a is cleared by an amount equal to the value shown by a counter 5-h by the judgement of a comparator 5-j as long as the data of a counter 5-f is smaller than the value shown by the couter 5-h. Therefore the user data is stepped and the head of the data of buffer 5-a is coincident with the head of the user data to be processed next. If the data of the counter 5-f is larger than the value shown by the counter 5-h, the address showing the head of the next user data is stored in an address pointer 5-d and therefore the next column selection can be carried out. Thus it is possible to secure the data base processing ability higher than a certain level and to improve the processing efficiency and speed.

Title: Rotary heat accumulation type heat exchanger
Inventor: IZUMI TAKAO
IPC: F28D19/04
Filed: 1989-06-26
Abstract: PURPOSE:To prevent radially irregular wears of seals without loss of sealability by forming a plurality of grooves having different lengths and extending radially form the rotating center on the end face of a core with which a crossbar seal is brought into slidable contact. CONSTITUTION:A plurality of grooves 20A, 21A, 22A having different lengths, extending radially from a center, are formed on both ends 1B, 1C of a core 1. The meeting times of the core 1 with seals 7A, 20A-22A upon one revolution of the core 1 are increased toward the center. A seal wearing speed is proportional to a contact surface pressure, and the higher the contact surface pressure increases, the faster the wearing speed increases. The speed is accelerated by the edge effect of the groove to be effected when the seal meets with the groove. As results, the radial wearing speed can be made uniform by suitably setting the number, the length of the grooves, etc. Thus, an irregular wear can be prevented without loss of sealability.

Title: Device for controlling electric vehicle
Inventor: SAITO KAZUO
IPC: H01M10/633
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To secure the range of an electric vehicle without using the residual capacity of a battery wastefully in the vehicle powered by a lithium-ion secondary battery even when outside air temperature is high. SOLUTION: Average output power Pave is calculated from the temperature rise rate ΔT/Δτ of the surface temperature of a battery Tbmax . When actual residual capacity Cr is larger than expected electric energy derived from this Pave , target average output power Pcal , which is needed until the residual capacity Cr is completely discharged, is calculated (Steps 101 to 106). If maximum output power Pmax is larger than the target average output power Pcal at the time of the calculation, the output of the battery is limited steadily to be headed toward the target average output power (Steps 107 to 111). These steps make it possible to delay the timing of limiting the output based on the temperature, thereby prolonging the period of normal travelign by that delayed period to extend the range of an electric vehicle.
