Abstract: A garment hanger clip is provided with a pair of clip jaws having lateral projecting portions or extensions which prevent or reduce unintended release of the clip jaws when a series of hangers is pressed or pushed together. The projections or release guards are advantageously located beneath the pivot point of the clip jaws so that lateral or sideward force applied to the guards tends to close the jaws even tighter.

Abstract: A data transfer rate control method inserts a stuff packet in real time to resolve the problem present in an ATM transmission for MPEG data. The method, for controlling a data transfer rate at which coded data are transferred in an asynchronous transfer mode may include the steps of: forming the coded data for an AAL layer (ATM Adaptation Layer); calculating an insertion timing for insertion of a NULL packet; inserting the NULL packet into the coded data of the AAL layer in consonance with the insertion timing, obtained by the calculation, for the NULL packet; and transferring, in the asynchronous transfer mode, the coded data of the AAL layer into which the NULL packet is inserted.

Abstract: In the present invention, the first communication device accepting the first LAN and the second communication device accepting the second LAN are connected through the ATM network. When data is transmitted from the second LAN to the first LAN, data transmitted from the second LAN is received by the first communication device through the second communication device and the ATM network, and held by the buffer unit until transmitted to the first LAN by the transmission part. The monitor part the storage quantity of the buffer unit. When the monitor part indicates the possibility that data overflows from the buffer unit, the control data generation part generates control data and transmits it to the second communication device. In the second communication device, the control part obtains the control data and reduces data quantity transmitted from the second communication device to the first communication device based on the control data.

Abstract: Source data is stored in a source data storage unit and a comparing device compares source data with destination data stored in a destination data storage unit. A destination address compressing unit compresses destination address information, and other accounting parameters are output with some delay. An accumulating device accumulates information from the destination address compressing unit as an address. A source address compressing unit compresses or delays information from an accumulating unit, and then outputs information. A source address carrier compressing unit compresses or delays information from the source address compressing unit, and then outputs information. A destination address source address carrier re-compressing unit compresses or delays compressed information from the source address carrier compressing unit, and then outputs information. A period abnormality detecting circuit in an accounting unit validates transfer data and prevents a wrong accounting process from being performed.

Abstract: A digital transmission equipment comprising an interface apparatus connected through a wired line between a transmitter-receiver which transfers a digital signal through a wireless communication link and a multiplexer connected to a terminal equipment. The interface apparatus communicates with a multiplexer with the I-interface frame format and communicates with an interface apparatus opposed through a transmitter-receiver by the frame format in which a synchronization bit string in this frame format is allocated to service information bits for a wireless communication link. Without changing a basic format of the I-interface signal from the multiplexer, the service information bit peculiar to the wired line can be arranged in the frame format.

Abstract: A system for determining the precision of a numerically controlled machine ool involves setting the machine tool control to define a circular path. A circular standard is then aligned with the machine tool to sense the desired circular path. A continuous or pointwise sensing, as a function of whether a path-controlled or a point-by-point-controlled machine is being measured, of the aligned standard is performed. A faulty machine tool does not accurately cover the defined circular path. Variations from the desired circle can be plotted and used for evaluation.
