Title: Hot wire type manifold flowmeter
Inventor: KANOU HIDEKI
IPC: G01F1/68
Filed: 1982-03-18
Abstract: PURPOSE:To eliminate the possibility for failure even if a flowmeter receives the impulse wave pressure which occurs in backfire or the like and directs from the down stream to the upper stream directly, by throttling the opening on the down stream side of a cylindrical member which contains a metallic wire for a hot wire to a tapered shape. CONSTITUTION:A ring 9 consisting of a metallic member is fitted in a cylindrical member 25 provided in a suction air pipe 2 forming a suction air line 1 and a metallic wire 10 for a hot wire consisting of platinum is extended rightly at a right angle to the direction where the suction air flows. Since the sectional shape of the air through-hole 26 of the member 25 is throttled to a tapered shape from the prescribed position 2b of the member 25 to a down stream end 25c, said member has the buffer function against the impulse wave pressure from the down stream by backfire or the like.

Title: Semiconductor switching device
Inventor: FURUHATA SHOICHI
IPC: H03K17/041
Filed: 1991-03-08
Abstract: PURPOSE:To make it possible to speed up a switching operation and eliminate switch damage by connecting a first semiconductor device and a semiconductor device in parallel, time-lagging the fluctuations in a drive signal than the first semiconductor device for the second semiconductor device, lowering the saturation voltage of the first semiconductor device than the second semiconductor device, and extending its falling time. CONSTITUTION:Both collectors and emitters of a first semiconductor device A and a second semiconductor device B are connected with each other in parallel in structure and they are driven by a common drive circuit D. The first semiconductor device A operates at lower saturation voltage for long falling time while the second semiconductor device B operates at higher saturation voltage for short falling time. An input resistor R is inserted in front of a gate of the second semiconductor device B and operated by a common drive signal, which forces a shutdown time of the second semiconductor device B to time-lag and carry out turn-off operation based on the short falling time of the second semiconductor device. This construction makes it possible to attain the high speed performance and low switching loss.

Title: Motion detecting device and image signal processor
Inventor: KONDO TETSUJIRO
IPC: G06T7/60
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To easily and higher precisely detect the motion of a whose screen such as pan, tilt, and scene change. SOLUTION: An activity detecting circuit 2 detects activity indicating the features of an image for each bloc, and compares the frame difference of the activity with a threshold for generating a flag indicating the presence or absence of the motion of block units. Flags fi and fi-1 of the temporarily continuing two frames are matched by a matching circuit 4. The patterns of the flags of a whole screen or the patterns of the flags of a macro-block constituted of plural blocks are compared so that a motion vector can be generated. A judging circuit 5 generates a scene ID indicating the motion of a whole screen (pan, tilt, zoom enlargement, zoom reduction, scene change, and pause), based on the motion vector.

Title: Data processor
Inventor: YOSHIDA KAZUMASA
IPC: G06F9/06
Filed: 1990-02-23
Abstract: PURPOSE:To optionally change the execution environment of each processing without describing an environmental condition in a processing program by previously setting up the environmental condition in an environment table memory correspondingly to the processing program. CONSTITUTION:An environmental condition setting means 1 sets up an environment condition such as a printer sort corresponding to a previously prepared processing program in the environment table memory 2. When the execution of a processing program is specified from a keyboard or the like, an environment processing means 3 reads out the environmental condition set up in the memory 2 and changes the execution environment of the specified processing program to an environment matched with the condition. Since the execution environment of each processing can be optionally changed without describing the environmental condition in the processing program, the environment can be simply set up even by a general user.

Title: Led lighting circuit
Inventor: OKANO YOICHI
IPC: H01L33/00
Filed: 1990-02-27
Abstract: PURPOSE:To simplify a circuit, and to reduce the size of a circuit board by mounting an LED, a gate IC driving the LED, an integrating circuit driving the gate IC and an input circuit applying an input signal to the integrating circuit. CONSTITUTION:When pulses of approximately 600mS are input to a CMOS gate IC 17, a capacitor 15 is charged through a resistor 14 and a diode 16. The charges are not discharged toward the resistor 14 owing to the diode 16, but discharged toward a CMOS gate IC 12 with a time constant determined by the capacitor 15 and the input impedance of the gate IC 12. Consequently, the gate IC 12 is turned ON for a period of approximately 200mS, and an LED 11 can be driven through a resistor 13, and can be lit. Accordingly, when the LED is lit by pulses of approximately several hundred mS in conventional devices, an IC such as a monostable multivibrator is used, but since the IC can be omitted, the circuit is simplified and the size of a circuit board is reduced.
