Title: Obstacle detecting device for vehicle
Inventor: HAYASHI MASAYUKI
IPC: G01S15/10
Filed: 1984-12-24
Abstract: PURPOSE:To prevent a flicker of display near the boundary of display distance by providing plural set values of reflection time having specific width, and storing plural measured values of reflection time when they are not within a set value range and outputting their minimum value and maximum value. CONSTITUTION:An ultrasonic wave is transmitted by a transmitter 14 to a target and the reflected wave from the target is received by a receiver 21; and a reflection time measuring means 30 detects the reflection time required between the transmission and reception of the ultrasonic wave. A reflection time setting means 41, on the other hand, sets plural set values of reflection time matched with the display distance as a main set value and subordinate set values which deviate from it by specific boundary width. Then, a reflection time comparing and deciding means 40 decides which boundary value range a measured value of reflection time is within and outputs the decision result. When the measured value is not less than the boundary value, plural values are stored in a reflection time selecting means 50 and the largest or smallest value among those stored value is outputted.

Patent JP-S61153387-A (JP)
Title: Heat exchanger
Inventor: KIDO OSAO
IPC: F28F1/12
Filed: 1984-12-27
Abstract: PURPOSE:To improve the heat transfer property of a single flat tube heat exchanger by a method wherein the heat exchanger consists of a flat tube, to the surface of which a large number of pins are planted vertically so as to give strong turbulence to the air stream flowing among the group of the pins by the pins in order to develop a large quantity of heat transfer between the pins and the air stream. CONSTITUTION:Heat is exchanged between air stream B flowing among pins 5 and the flow in a flat tube 3. In this case, a large quantity of heat transfer is realized between the pins 5 and the air stream B, because the air stream B is given turbulence by the pins 5 and the pin 5 has almost no thick boundary layer, which develops in a flat plate fin and hinders the heat transfer. In addition, the staggered arrangement of the pins onto the flat tube 3 gives far more turbulence to the air stream B, resulting in giving the improving effect for remarkably large heat transfer. Furthermore, because the pin 5 has a circular column form, no re-straightening of the air stream B by the pin 5, which occurs by a flat fin in such a manner that the flat fin straightens again the air stream given turbulence by a heat transfer medium tube, occurs.

Title: Variable speed controller for induction motor
Inventor: WATANABE KATSUYUKI
IPC: H02P27/06
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To miniaturize a controller and to reduce its cost by absorbing generated power with a system other than generator braking or regenerative braking and to solve long deceleration time that is caused by low deceleration rate by a software system. SOLUTION: In variable speed controller provided with an automatic voltage controlling part 10 for holding the output voltage of an inverter 2 in a state of a constant V/f ratio against fluctuation of a DC voltage, the speed deceleration state of an electric motor is detected from the rise of a DC intermediate voltage by the comparing part 113A of an output voltage stressing circuit 13. This detection causes a changeover part 13B to raise the output of the automatic voltage controlling part 10, thereby increasing the output voltage of the inverter. As a result, the efficiency of power conversion in the electric motor and inverter is lowered and, by increasing the power consumed by the motor and inverters, the voltage rise of the DC intermediate circuit is suppressed.  This invention includes detection of the speed deceleration state of the motor from its effective power and the direct raise of the current setting signals of the inverter by the detection of the speed deceleration state.

IPC: G01L9/10
Filed: 1986-11-21
Abstract: PURPOSE:To accurately and easily perform proper driving control, etc., on a mechanism part by leading out pressure variation as linear inductance variation. CONSTITUTION:As pressure applied into a case part 11 from a coupling cylinder 13 operates on a diaphragm 20, the diaphragm 20 is displaced against a compression spring 25, and magnetic body 23 slides to nearby a coil 23 to cause variation in the inductance of the coil 23, so that the pressure can be detected.
