Title: Transmission/reception system of message service request signal
Inventor: KANO HARUKI
IPC: H04M3/50
Filed: 1979-10-24
Abstract: PURPOSE:To ensure an effective transmission/reception of the message service request signal, by performing the reception process of the message service request in the same program to the common conrol device regardless of the system of recep- tion. CONSTITUTION:In case e.g. an alarm service is given from a subscriber of a long- distance telephone exchange OFF to the message service center MSC, the register sender RS receives and accumulates the equests from the subscriber telephone SUB to then transfer the information of the dial number and others to the common control device (not shown in the figure). Then the telephone number and the number dial indicating the desired get-up time arrive and are thus received by the sender RS to be sent to the corresponding PB signal register R via the trunk MST. Then the register R sends the information to the common control device CNT, and thus the device CNT performs the message work. In this way, an effective transmission/ reception is possible for the message service request signal.

That means that rotation angles about the panning axis, the roll axis, and the tilt axis perpendicular to each other are detected to be supplied to pursuit a ratio setting part 3. The pursuit ratio setting part 3 multiplies pursuit ratios gamma, alpha, beta as different values for a panning angle, a roll angle, and a tilt angle respectively to be outputted to a camera angle setting part 4. The camera angle setting part 4 drives respective motors 6a-6c based on the set panning angle, roll angle, and tilt angle. The pursuit ratios gamma, alpha, beta are changed in inverse proportion to a zoom magnification of a camera.

Title: Facsimile communication control equipment
Inventor: NAGAMINE TAKASHI
IPC: H04N1/32
Filed: 1988-06-03
Abstract: PURPOSE:To cancel a trouble that CCU on a downstream becomes inoperative due to the trouble of CCU by providing selection circuits in respective CCUs and transmitting interruption permission signals in both directions from the downstream to an upstream and from the down stream to the upstream. CONSTITUTION:Since a line selector switching signal line 604 is fixed to H by CPU, the selector output of CCU 10N includes the output Q' of a preceding stage FF20N-1 and is led to an AND gate 30N. Consequently, the interruption permission signal is transmitted from the upstream to the downstream. When CCU 10N generates an interruption request and CPU has generated the interruption permission signal to an interruption permission signal line 600 and there is no response to an interruption permission response signal line 603, CCU 10N-1 recognizes abnormality and CPU immediately fixes the line 604 to L and transmits the interruption permission signal to an interruption response signal line 602. At that time, FF outputs Q' which are respectively in downstreams by one are set to appear in respective line selector outputs, and the interruption permission signal is transmitted from the downstream to the upstream, whereby they can reach CCU 10 when the line 600 is connected to the line selector input of CCU in the lowest stream.

Abstract: PURPOSE:To enable small-diameter test-pieces to be used by clamping two test-pieces by a couple of driving rollers which are equal in diameter to or larger than the test-piece. CONSTITUTION:Driving disks 10a-10c on an upper-stage side and driving disks 10d-10f on a lower-stage side rotate at the same rotational speed in the mutually opposite direction between the upper-stage and lower-stage sides as shown by arrows to rotate driving rollers 20a and 20b clamped by the disks 10a-10c on the upper-stage side and the test-piece 30a clamped by them. Further, driving rollers 20c and 20d clamped by the disks 10d-10f on the lower-stage side and a test-piece 30b clamped by them are rotated in the opposite direction from the upper-stage side. When the disks 10a-10c and disks 10d-10f are equalized in rotational speed, the test-pieces 30a and 30b come into simple rolling motion and no rolling frictional force is generated. When they are rotated at different rotational speeds, on the other hand, the test-pieces 30a and 30b rotate at different peripheral speeds and a rolling slide frictional force is generated between the test-pieces 30a and 30b.
