Patent JP-H06214016-A (JP)
Title: Signal processing device for doppler radar
Inventor: HATA KIYOYUKI
IPC: G01S13/52
Filed: 1993-01-18
Abstract: PURPOSE:To remove the influence of a reflected signal due to topography or the like so as to enable meteorological observation with high accuracy by constituting a signal processing device for a Doppler radar in such a way as to select one output between an average speed detecting part and a pulse pair processing part. CONSTITUTION:A digital signal is inputted into an MTI processing part 2 and a frequency analysis processing part (FFT) 5. The processing part 2 removes the reflected signal due to topography or the like from the input signal, and the input signal is inputted into a pulse pair processing part 3. The average speed and standard deviation are then detected from speed elements and inputted into a signal switching part 8. The FFT 5 performs frequency analysis and sends the result to a clutter removing part 6. The clutter removing part 6 inputs a signal, obtained by removing the reflection signal due to topography or the like from the input signal, into an average speed detecting part 7 where a speed signal is detected and inputted into the switching part 8. The clutter removing part 6 makes a judgment according to the intensity of the reflection signal due to topography or the like in the input signal on the basis of the output signal of the FFT 5. At the time of the intensity being the specified value or less, the switching part 8 is controlled to select the output of the processing part 3, and at the time of being the specified value or more, the switching part 8 is controlled to select the output of the detecting part 7.

Title: Disk pad and manufacture thereof
Inventor: ARIMITSU HIROSHI
IPC: F16D69/00
Filed: 1990-01-31
Abstract: PURPOSE:To prevent or minimize brake squeak by making the specific gravity of central portion of a frictional member larger than that of the peripheral portion. CONSTITUTION:After a frictional member 1 is stuck to a back metal 2, slide surfaces are opposed to each other and set in a heat treatment jig 3. Further, a spacer 4 is interposed in the central portion between both slide surfaces to be subjected to heat treatment while being pressurized. Thus, the end of the frictional member 1 is made softer than the central portion. When pressure on the end is partially raised, the winding inclusion of a disk pad into a rotor can be prevented by hardly changing compression strain due to compression deformation. Thus, the brake squeak can be prevented or minimized.

Title: Depth sensing type underwater acoustic transponder
Inventor: AKITOMO KATSUFUMI
IPC: G01S15/74
Filed: 1988-02-03
Abstract: PURPOSE:To eliminate the need for calibration and to easily know the depth of the transponder by providing a depth sensor which detects external hydraulic pressure so that depth information is included as part of a transponder response signal. CONSTITUTION:The acoustic signal from a pinger, etc., is received by a transmitter receiver 1 and converted into an electric signal, which is amplified and shaped by a receiving circuit 4 and sent to a control circuit 2. A control circuit 5 decodes the received signal and operates according to the signal when the signal is a command signal. When the signal is an inquiry signal, a response signal is generated by a sending circuit 3 according to the mode of the transponder and depth detected by a depth sensor 2 at this point of time. The response signal generated by the sending circuit 3 is amplified and the transmitter receiver 1 is driven to send a response acoustic signal into water. Consequently, the need for calibration is eliminated and the depth of the transponder is easily known.

A carry signal Cy is outputted to the MPU 2 when the count value attains a zero value. The input to a D/A converter 4 is thereby interrupted. The one clock is a 1/2 pit when one pit length is considered as a unit and, therefore, the pit of 1 to 2.5 pit length is obtd.

Title: Uranami bead detecting method in plasma key hole welding and groove profiling method
Inventor: FUJIOKA TADASHI
IPC: B23K10/00
Filed: 1985-02-09
Abstract: PURPOSE:To forms automatically good URANAMI bead by detecting the existance of the plasma arc which penetrate to the back face of the material to be welded and by detecting whether the URANAMI bead is formed or not. CONSTITUTION:The output signal of adder 19 becomes zero because of the output signal of photosensors 7a-7d becoming zero when plasma arc 4 does not penetrate the material 1 to be welded and the valve opening for plasma gas of welding torch 3 is made bigger by this signal. When the plasma arc 4 penetrates the material 1 to be welded, amplifier 16 is actuated by the output signal of the adder 19. In case of the center of the welding torch 3 and the groove center being coincided with this state the output signal of the comparator 15 becomes zero due to the output signal of the adder 13 and 14 being equal and the input signal of servo amplifier 17 becomes zero. A profile motor 18 is therefore not rotated and the welding torch 3 does not move to the right and left for the groove.

IPC: F25B5/02
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To reduce the passing sound of refrigerant upon starting a rear side air-conditioning unit 17. SOLUTION: A pressure reducing means provided in a front side air- conditioning unit 13 is constituted of a temperature type expansion valve 14, regulating the superheating degree of outlet refrigerant of an evaporator 15 mechanically, while a pressure reducing means provided in a rear side air- conditioning unit 17 is constituted of an electric expansion valve 190, controlling the superheating degree of outlet refrigerant of an evaporator 20 electrically. The opening degree of the electric expansion valve 190 is increased gradually during a predetermined period of time immediately after starting the rear side air-conditioning unit 17. According to this method, the inflow of much amount of refrigerant suddenly into the evaporator 20 upon starting is prevented and the passing sound of refrigerant can be reduced.  When the cooling load of the rear side air-conditioning unit 17 is small, an objective superheating degree is changed to a second objective value T2, smaller than a first objective value T1 in usual. According to this method, the opening degree of the electric expansion valve 190 is increased forcibly even upon a low load whereby the returning of oil into a compressor 10 can be improved.

Title: Snubber circuit of rectifier
Inventor: FURUYA SHINICHI
IPC: H02M7/12
Filed: 1989-02-01
Abstract: PURPOSE:To reduce the duty of a snubber reactor by controlling the on and off of a switching element by the use of a current detector to detect the current flowing to a snubber diode and a switching control circuit to send out on/off signals to the switching element by inputting the signal from this current detector 21. CONSTITUTION:If the current starts to conduct to a snubber diode 11 again after it is detected by a conducting current detection means 21 that the conduction of the snubber diode 11 is off when the energy absorption to a snubber capacitor 12 is completed, this current is judged as the one shunting to a snubber reactor 13. At the conduction starting point of this current, the current to the snubber reactor 13 is interrupted by opening a switching element 15 by a switching control circuit 20. Application of surplus duty to the snubber reactor 13 can thereby be prevented.
