Title: Voltage detecting probe
Inventor: KATOU TAKAYUKI
IPC: G01R15/04
Filed: 1979-09-28
Abstract: PURPOSE: To convert in a high accuracy the secondary voltage including the DC component into the low-voltage signal for detection of the voltage, by providing the partial pressure resistance and the compensating capacitor to the internal circiut of the probe.  
     CONSTITUTION: This voltage detecting probe detects directly the electric signal out of the ignition circuit of the internal combustion engine consisting of the ignition coil, the coil cord, the distributor, the plug cord, the ignition plug and others. In such probe, the conductor 2 is connected between the terminal 1 connected to the secondary output terminal of the ignition coil and the terminal 3 connected to the coil cord end. Thus a conduction is possible for the secondary voltage of a high level. And the secondary voltage to be applied to the conductor 2 is by-passed from the middle of the conductor 2 by the partial pressure resistances 4 and 5 plus compensating capacitors 6 and 7 to be led to the earth line E. The detection signal is led by the signal line 9 from the joint (1st gathering joint) between the resistances 4/5 and the capacitors 6/7.

Title: Mask mobile type contour extraction circuit
Inventor: AOKI TAKASHI
IPC: G06T7/00
Filed: 1986-06-02
Abstract: PURPOSE:To extract a contour having sharp density change and a contour having comparatively moderate density change by executing processing having an effect similar to the movement of a mask area based on a past mask area operating result. CONSTITUTION:The prescribed number of data for the past mask areas is stored in a register 17. An adder 18 adds past data stored in the register 17 successively such that the current data and the data just before the current data, the current data and the data before the current data by two data, or the current data and the data before the current data by three data respectively are added, and sends the added result to a comparator 19. The comparator 19 compares the added result sent from the adder 18 successively with a threshold and a minimum value exceeding the threshold is written in a bit map memory 16 as the contour. Consequently, processing having an effect similar to the movement of the mask area is executed. Thereby, the contour having sharp density change and the contour having comparatively moderate density change can be extracted.

Title: Detection method for bend of base of fluorescent lamp
Inventor: FUNAKOSHI AKIO
IPC: H01J9/42
Filed: 1986-06-04
Abstract: PURPOSE:To attain a resistance to disturbance such as dust, enable maintenance- free use and keep accurate and stable detection, by using proximity switches. CONSTITUTION:A glass bulb 1 is held between fixed rails 12 and V-grooved members 11 by a centering device so that the glass bulb is positioned. The shafts 8 of an inspection device are moved in a horizontal direction 10 at both ends of an already positioned lamp so that a contact member 3 is put in touch with a base 2. If proximity switches 9a, 9b are set to be turned off in the condition that a contact member 4 and a disk 7 are parallel with each other, the distance between the contact member 4 and the disk 7 decreases because of the bend of the base. This action turns on the proximity switch 9a, but the distance for the other proximity switch 9b increases to keep it turned off. If the proximity switches 9a, 9b are turned on beforehand on the contrary, the distance for the proximity switch 9a decreases to keep it turned on, but the distance for the other proximity switch 9b increases to turn it off. The bend of the base can thus be detected depending on whether the proximity switches are turned on or off.

Title: Method for mounting optical fiber tape on connector
Inventor: NISHIWAKI TOSHIMITSU
IPC: G02B6/08
Filed: 1992-04-21
Abstract: PURPOSE:To mount an optical fiber tape in a connector properly by automatically knowing the direction across the width of the optical fiber tape accurately. CONSTITUTION:An object sensor 3 is installed in a specified position near the termination of an optical fiber tape 4 which is cut into widths asymmetrically, and properness of the direction across the width of the optical fiber tape is distinguished depending upon whether the sensor 3 has sensed object or not.
