A process sort test circuit and methodology for determining performance characteristic of an IC chip. The circuit is located on an IC chip itself and comprises an input for receiving an input signal; a first path from the input to a first output for transmitting the input signal to the first output, the first path sensitive to variations in a manufacturing process for the IC chip; a second path from the input to a second output for transmitting the input signal to the second output, the second path being substantially less sensitive to the variations in the manufacturing process for the IC chip; and, a pulse generator device coupled to the first and second outputs for detecting a difference in arrival times of the input signal at the first and second outputs and for outputting a sort signal if the difference is of a preselected magnitude. The sort signal enables output indication of a performance characteristic of the IC chip.

A method of measuring the amount of dislocation of the cervical vertebrae of the patient includes a step of defining, on the base posterior view, an end point on a line connecting a point representing the front end of the nasal septum and a point being equidistant from a pair of ocular orbits; a step of determining, on each side of the base posterior view, a point of intersection (or contact) of the "profile of a foramen magnum of a skull" and the region where a condyle of the skull is joined to, or in close proximity to, a superior articular pit of atlas; and a step of defining, on the base posterior view, a bisector of the angle which a line connecting the front end point to one of the points of origin forms with respect to another line connecting the front end point to the other of the points of origin. The amount of dislocation of the cervical vertebrae is determined by means of the bisector. In the case of the atlas, points of foramen transversariums representing points of the substantial center of the foramen transversariums of the atlas are defined on the image of the base posterior view. The amount of dislocation of the atlas is calculated by measuring the distance between one point of foramen transversarium and the bisector and the distance between the other point of foramen transversarium and the same.

Highly elastic heat-bonding conjugated fibers capable of providing a fiber structure having excellent recovery from compression and compression durability and a high level of air permeability comprise a thermoplastic elastomer component and a crystalline nonelastic polyester component having a higher melting point than that of the elastomer as constituent components thereof and can be provided by arranging the elastomer component in a crescent shape in the circular fiber cross section of the bonding conjugated fibers and specifying the geometrical dimensions (a shape occupied by each of the two components constituting the heat-bonding conjugated fibers) therein.

A control system for collectively supervising a plurality of copiers or similar image forming apparatuses connected to a control device by communication lines with or without the intermediary of communication control units. To down-load data relating to image formation, the control device determines whether or not a copier of interest is in an inoperative state and, if it is in an inoperative state, automatically sends the data to the copier via a telephone line, an exchange, and a communication control unit. This data is written to storing means built in the copier. To up-load data relating to image formation, the control device causes each copier to automatically send the data stored in the storing means and stores the data in memory means. Up-loading is effected at an optimal time other than the time when the copier is performing an automatic adjustment, is in use, or is quite likely to be used.

Calibration systems and techniques for analog phase-lock loops (PLLs) providing the capability to dynamically maintain a constant damping factor. Damping factor is calibrated by automatically setting a reference bias current I.sub.r to the PLL's charge pump such that the charge current I.sub.c output therefrom maintains the desired PLL damping characteristic. The technique presented involves selecting a known first frequency F.sub.1 and allowing the PLL circuit to reach steady state, after which a known second frequency F.sub.2 is applied and the PLL circuit is monitored to determine whether steady state at this second frequency F.sub.2 is accomplished within a predetermined target time T.sub.x, which corresponds to the desired damping factor. The determination of whether lock occurs within the target time T.sub.x is then employed to automatically set the reference current I.sub.r.
摘要:
Calibration systems and techniques for phase-locked loops (PLLs) provide precise setting of the center frequency and/or uniform voltage controlled oscillator (VCO) gain characteristics. Center frequency is calibrated by imposing a selected center frequency at the output of the PLL and driving the control voltage V.sub.c across the PLL's filter to a predefined, steady state voltage indicative of PLL circuit calibration. The approach can be employed to calibrate any imposed VCO frequency output. VCO gain calibration is accomplished by employing the center frequency calibration technique only with a low frequency point imposed on the VCO output. A high frequency point on the transfer function is calibrated by applying a known voltage across the filter and driving the VCO output to a corresponding calibration frequency. Once a low frequency point and a high frequency point are calibrated, the slope of the VCO transfer function is defined. Various integrated PLL/calibration system embodiments are presented.

A container holder capable of holding various containers, such as bottles and cans, comprises a deformable container-holding member made from a plastic material, a holding frame, and an adapter plate. The central portion of the holding member is divided into several tongues, and a central hole surrouded by these tongues is formed. The holding member is sandwiched between the adapter plate and the holding frame. Depending on the kind of the container held by this holder, the adapter plate is replaced with another adapter plate. Also disclosed is a container carrier in which container holders as described above are detachably mounted. An apparatus for handling containers using this container holder comprises mechanisms for performing these handling operations and conveying the container carrier between stations for the handling operations while the containers are received in the container holder. Equipment for warming or cooling containers received in said container carrier comprises mechanisms for repeatedly turning the carrier upside down.
