Abstract: A d.c. restore circuit for a multi-channel remote video interconnect circuit (20) is situated at the output end (25) of the interconnect circuit for minimum capacitive loading and to reduce power requirements for a video driver at the input end of the interconnect circuit. A resistor/diode voltage divider network is coupled between the output of the interconnect circuit and the cathode or grid of a CRT, with a capacitor in series with the output of the interconnect circuit to block any d.c. component of the video signal from the video driver (10-12). A fixed voltage is applied at one end of the divider network and a variable current source is coupled to the other end. The current from the current source determines the d.c. potential at the cathode or grid.

Abstract: It is well-known to use one or more valve actuators in injection molding equipment. However, problems are obtained when the valve stem of the valve actuator is no longer usable, for example, due to wear and/or breakage. In conventional arrangements, the whole valve assembly is removed and the valve stem is replaced. However, as each valve has an optimum length for the associated valve stem, replacement of a valve stem by one which is too long or too short impairs the operation of the equipment. Described herein is an adjustable valve stem apparatus (10) adapted for use in an injection molding equipment or device comprises a cylindrical body (12) comprising internally threaded fixed portion (14) and moveable portion (16) threadably mounted on a double-ended screw (30). Moveable portion (16) has a means (26) for removably mounting a valve stem (28) which communicates with a mold cavity. The double-ended screw (30) has a socket (38) formed in its top portion for adjusting the moveable portion (16) relative to the fixed portion (14) thereby correspondingly axially displacing the valve stem (28) from a first to second position relative to the mold cavity.

Abstract: The optimum programming voltage in programmable memory arrangements such as EPROMs, and in particular EEPROMs, depends on production tolerances, which can be externally determined only with difficulty. Therefore, measures are proposed which permit optimum setting of the programming voltage by using an additional transistor with floating gate which is constructed in just the same way as the transistors of the memory cells and which consequently has the same characteristics with respect to the programming voltage as well. This additional transistor lies in series between the high voltage usually generated on the chip and the programming voltage input of the actual memory matrix. A description is given of a circuit and the sequence of the control voltages required by the said circuit, by which the additional transistor is set. <IMAGE>

Abstract: A clamp fitment includes a pair of holding members H1, H2 each capable of clamping a pipe section P1, P2, a coupler 6 mounted between both the holding members H1, H2 for relatively rotatably but unseparatably coupling the holding members H1, H2, and a lock mechanism L mounted between both the holding members H1, H2 for restraining the relative rotation of the holding members at any time in positions in which the pipe sections P1, P2 clamped in the holding members intersect each other at right angles. The single clamp fitment for connecting the pipe sections can be used properly as either a "swivel type" in which the angle of intersection of the pipe sections can be freely selected or an "orthogonal type" for unifying the pipe sections in a square fashion. This eliminates the need for a worker to carry two kinds of clamp fitments to a working field, leading to simplified handling and management of the clamp fitment.

Abstract: A shared line appearance feature may be implemented on a plurality of telephone station sets (e.g.121,122,128) which are connected to different telecommunication switching systems (105,101,106). The telecommunication switching systems can be interconnected to each other via the public telephone network (114) utilizing standard telecommunication links (151,150,155,157,160,161). A software application program (666) provides a termination point for a directory number that is associated with a shared line appearance. The software application program (666) receives all incoming calls directed to the directory number and determines the operations that should be performed with respect to the telephone station sets (e.g.121,122,128) terminating the shared line appearance. The software application program directs the incoming calls to the telephone stations sets regardless to which telecommunication system each of the telephone station sets is interconnected. An outgoing call from one of the telephone station sets is switched to the software application program which then switches the outgoing call to the destination telephone terminal as if the outgoing call had originated at the location of the software application program. With respect to the outgoing call, the software application program also transmits messages to the other telephone station sets terminating the shared line appearance, so that those telephone station sets can indicate that the shared line appearance is busy.

Abstract: A digital video tape recorder ("VTR") including a recording and playback circuit. The recording circuit selects data useful for generating images during trick playback operation and records the data in trick play tape segments arranged on a tape to form fast scan tracks. Each fast scan track on a tape comprises trick play tape segments located on a diagonal of the same angle as the angle at which the heads of a VTR are expected to pass over the tape during trick play operation. Data which is used for at least one mode of trick play operation is recorded in each trick play tape segment. The data may also be used during normal playback operation. The recording circuit records normal play data in normal play tape segments. Normal play and trick play tape segments may be arranged to form normal play tracks on the tape, each fast scan track crossing multiple normal play tracks. The playback circuit includes a packet filter, a trick play servo control circuit and a VTR command generator circuit. The packet filter reads packet headers of data packets read from the tape and outputs only data packets intended for use during a user selected mode of VTR operation. The trick play servo control circuit controls tracking so that the heads pass over the fast scan tracks at the correct location and angle. The VTR command generator generates commands to a receiver indicating when the VTR is in trick playback mode.

Abstract: The periphery of a disk (50) having flexibility is fixed to a sensor casing, and a force applied to the central portion is detected. A doughnut disk-shaped piezoelectric element (20) is positioned on the upper surface of the disk (50), and upper electrode layers indicated by patterns of D1 to D6 are formed on the upper surface of the piezoelectric element (20). Further, lower electrode layers similarly having pattern of D1 to D6 are formed on the lower surface of the piezoelectric element (20), and the lower surface of the lower electrode layer is fixed on the upper surface of the disk (50). Six detection elements D1 to D6 are formed each of which is constituted by a pair of upper and lower electrode layers and a portion of piezoelectric element (20) put therebetween. Thus, force components exerted at an origin defined in the central portion of the disk (50) in respective axes directions of X, Y, Z can be detected based on charges produced in detection elements D1, D2, detection elements D3, D4, and detection elements D5, D6, respectively.
