Title: Automatic terminating resistor on/off mechanism
Inventor: SONE KAZUHIKO
IPC: G06F3/00
Filed: 1991-09-19
Abstract: PURPOSE:To prevent mis-setting from being performed by providing an ON/OFF switch for a terminating resistor circuit at each input/output connector of a device, and automatically turning on/off the terminating resistor circuit depending on the presence/absence of a connection cable. CONSTITUTION:The connection cable (not shown in Figure) is inserted to the input/output connecter 1 of a digital-chain connected device (not shown in Figure). A switch 2 is turned on when the cable is inserted to the input/output connector 1, and the terminating resistor circuit (not shown in Figure) is turned off. When no cable is inserted to the input/output connector 1, the switch 2 is turned off, and the terminating resistor circuit is turned on. In other words, no insertion of the cable means that no connection to the next device is performed, therefore, the terminating resistor circuit is turned on. Namely, the insertion/extraction of the cable functions as the switch, which turns on and off the terminating resistor circuit. Thereby, it is possible to omit the setting of a conventional switch and the insertion of a terminating connector, and to prevent the mis-setting and insertion forgetting from occurring.

Title: Centrifugal, belt-driven automatic stepless transmission for vehicle
Inventor: MIYAZAKI KUNIO
IPC: F16H9/12
Filed: 1983-12-19
Abstract: PURPOSE:To provide a compact nonstage speed change gear with a reduced rolling load by disengaging the pressed contact of a variable diameter flywheel agaist a V-belt when a clutch is disengaged so that the transmission of rotation from the driven shaft to the drive shaft may not be allowed. CONSTITUTION:An output shaft 1 and a drive shaft 3 which are concentrically arranged are connected by a centrifugal clutch 8. A variable diameter flywheel 5 on the drive side gives a smaller belt-wrapping diameter as a weight roller 7 is positioned near to the center to expand the gap between two side plates 5A, 5B, while a variable diameter flywheel 12 on the driven side gives a larger belt- wrapping diameter as a movable side plate 12B is drawn near to a stationary side plate 12A by the force of a spring 14 to narrow the gap between the two side plates. When the centrifugal clutch 8 is disengaged to disconnect the transmission of power of the drive shaft 3, the gap in the drive side variable diameter flywheel 5 is caused to open wider enough not to press the sides of a V- belt 13 by setting the amount of displacement of the movable side plate 5B larger than prior types.

Title: Method for printing character string with underline
Inventor: HIRAKAWA TAKAYUKI
IPC: B41J29/36
Filed: 1988-09-26
Abstract: PURPOSE:To reduce irregularities in printing underlined characters and enhance a printing speed by a method wherein after a character string to be applied with an underline is all printed, an underline corresponding to the width of the character string is dividedly printed by the width of the underlined character. CONSTITUTION:When a character string 'WiW' is printed, a printing head firstly prints the character string 'WiW' without an underline from a position P1 and travels to a position P2. Thereafter, the head is moved in the reverse direction from the position P2 to a position P3 by a distance of (the width of the top character 'W'/2)+(the width of the character 'i') + (the width of the last character 'W'/2)+{(the width of the top character 'W')-(the width of the underlined character)}/2. Thereafter, the printing head is moved forward by (the character string width, i.e., the addition of the width of the first character 'W', that of the next 'i', and that of the last character 'W')/(the width of the underlined character) to print first, second, and third underlined characters L1, L2, L3 in order, thereafter being moved to a position P6 to print a fourth underlined character L4. As a result, irregularities in printing can be reduced, and a printing speed can be enhanced.

Title: Color video signal processing circuit
Inventor: YAMAMOTO KAZUMITSU
IPC: H04N9/68
Filed: 1990-09-12
Abstract: PURPOSE:To adjust color reproducibility and saturation or the like effectively by allowing the processing circuit to receive a chrominance subcarrier having a normalized level and a chrominance subcarrier whose level is adjusted and to select either of them. CONSTITUTION:A switching signal given to an input terminal 16 is fed to a changeover switch circuit 15 via a switch 17. The switching signal is synchronously with a blanking pulse and throws an output terminal 15-3 of the changeover switch circuit 15 to the position of a 1st input terminal 15-1 during the blanking period and to the position of a 2nd input terminal 15-2 during the video period other than the blanking period. Thus, a chrominance subcarrier having a normalized level is given to the output terminal 15-3 during the blanking period and a chrominance subcarrier whose level is adjusted optionally by a variable resistor 12 is given to the output terminal 15-3 during the video period. Thus, the color reproduction at the receiver side is controlled to a lower level in which color noise is eliminated.

Title: Magnetic flaw detector
Inventor: ABE NAOKI
IPC: G01N27/84
Filed: 1992-09-09
Abstract: PURPOSE:To grasp an object to be inspected in a stable state and to prevent the lowering of flaw detecting capacity by connecting respective grasping arms to a synchronizing means and synchronizing the movement in respective grasping directions to allow the moving speeds of electrodes to perfectly coincide with each other. CONSTITUTION:When a work 21 is grasped by grasping arms 31, 32, the movement of the grasping arms 31, 32 can be synchronized by a synchronizing means 45. That is, since a gear 48 is meshed with both of the tooth part 47a connected to one grasping arm 31 and the tooth part 46a connected to the other grasping arm 32, only one grasping arm can not be moved precedingly and the moving speeds of respective electrodes 33, 34 can be allowed to perfectly coincide with each other. Therefore, the shift of the grasping timing of the work 21 by the electrodes 33, 34 can be certainly prevented. When the work 21 is grasped by the electrodes 33, 34, a current flows and the work 21 is magnetized. Since the work 21 is grasped in a stable state, the flaw in the direction (axial line direction C) crossing the axial direction of the work 21 at a right angle can be certainly detected by sprinkling a magnetic powder soln.

SOLUTION: Preferably in this adjusting method of a polar relay, when demagnetization of permanent magnets is carried out continuously, an arbitrary permanent magnet is demagnetized, other permanent magnets are demagnetized, based on measured data of an open/close characteristic of a contact part after a spring member is fixed, and when demagnetization of the permanent magnets is carried out by arranging adjusting permanent magnets in the vicinity of the permanent magnets, the number of the arranged adjusting permanent magnets is varied, the distance between the adjusting permanent magnets and the permanent magnets are varied, and a current is carried to each of the adjusting permanent magnets.  Since the dispersion of the magnetomotive force of the permanent magnets before demagnetization in an aggregate having the same kind of history is not larger than that among aggregates having different histories, the magnetomotive force of the permanent magnets after demagnetization is hardly dispersed, with respect to a prescribed magnetomotive force corresponding to attraction of an electromagnet by carrying out the demagnetization of the permanent magnets for every aggregate having the same kind of history at a time.
