Title: Method and device for calculating intersecting point between area boundary on picture and known function
Inventor: TSUKADA HIROSHI
IPC: G06T7/60
Filed: 1986-12-11
Abstract: PURPOSE:To decrease the number of timers of transfer and to shorten the calculation time by transferring once the density of a dividing point to compare it with the density of an area and defining only one of two areas divided at the dividing point as a checking range. CONSTITUTION:The images picked up by an ITV camera 7 are stored in a picture memory 9 through an A/D converter 8 so that the areas P and phi have different density ranges. The coordinates of points A and B of known functions of areas P and phi are stored in the coordinate storing memories 1 and 2 respectively. A middle point coordinate calculating circuit 3 outputs the point A and a middle point M to an intersecting point discriminating circuit 4 from both points A and B. When the discrimination condition is not satisfied, the circuit 3 rewrites the set points of an area different from a dividing point into two points A and B of a new known function for the calculation of the intersecting point coordinates.

Title: Terminal equipment for fire alarm facility
Inventor: ISHII KENJI
IPC: G08B17/00
Filed: 1990-10-30
Abstract: PURPOSE:To confirm that the action of returning return information to a receiver has actually been started by a terminal device by providing a light emitting element which comes on when the return of the return information to the receiver is enabled. CONSTITUTION:The base of a transistor TR1 is connected to an enable signal outputting port OUT2 of a microcomputer MPU via a base resistor, and a light emitting diode LED is connected to the collector of the transistor TR1. The light emitting diode LED comes on when it is enabled to return the return information to a receiver RE after an address in polling coincides with the self address of the terminal device. Thus, when the terminal device receives a return command from the receiver RE, it can be confirmed that the terminal device has actually started the action of returning the return information to the receiver RE.

Title: Vertical deflection circuit
Inventor: TAKESHITA MASAHIRO
IPC: H04N3/23
Filed: 1986-12-10
Abstract: PURPOSE:To correct the linearity for the elongation at the upper/lower end of the screen by extracting a voltage of a part corresponding to the upper/lower end of the screen with respect to a vertical deflection current, superimposing the voltage onto a voltage corresponding to the entire deflection current so as to obtain a feedback voltage. CONSTITUTION:A voltage at the upper/lower end of the deflection current across a resistor 5' is given across a resistor 13 by using diodes 11, 12 and selecting the resistance of the resistor 5'. In superimposing the voltage across the resistor 13 onto a voltage from a resistor 10 via a resistor 14, the voltage subject to elongation of the upper/lower end is fed back to a vertical oscillation and sawtooth wave generating circuit 1. As a result, the deflection current flowing through the deflection coil 3 has a waveform giving an effect of shrinking the upper/lower end and the picture on the screen is subject to correction of the upper/lower end elongation. In varying the resistance of the resistor 14, the linearity of only the upper/lower end is corrected.

Abstract: PURPOSE:To avoid the output deterioration of a magnetic head due to attachment of an adhesive matter by forming grooves to the magnetic tape rubbing surface of the head and also protruded streaks which extend along the rubbing direction of a magnetic tape and have contacts with both end parts of a pad with a space secured to the magnetic tape to reduce the pressure contact force between the part and the tape. CONSTITUTION:The linear grooves 15 and 15 are formed in the prescribed width on a tape rubbing surface 6 and along the both edges of the coming-in side and the going-out side of a magnetic tape at a magnetic core part 2. The fixing agent 4 is removed out of the groove parts 15. Then, the protruded streaks 16 and 16 are formed on the surface 6 to sandwich an opening part 5a where the core is exposed on the surface 6 and then to enclose a magnetic tape rubbing area. Thus, both streaks 16 extend over the entire width of the surface 6 and along both edges of an approximately oblong surface 6 in the direction parallel to the tape rubbing direction. As a result, an adhesive matter is prevented from attaching to the part of the core 2 as the tape rubs. Then, the press contact force of a pad 11 is reduced and the wear of a magnetic core part is suppressed.
