摘要:
A hub for a local area network according to one embodiment of the present invention includes a plurality of communication ports connected to each of nodes in the network, through which a signal is transmitted among the nodes, a signal processing circuit having at least the functions of repeating the signal among the nodes and reshaping a waveform thereof, and a power supply circuit for supplying a dc current for driving the signal processing circuit. The power supply circuit further comprises an ac/dc converter for converting an ac current applied from an external ac power supply without passing through a power switch thereto into a predetermined dc current and supplying the dc current to a load circuit including the signal processing circuit without passing through a power switch, a backup secondary battery, a charging circuit for trickle charging the dc current output from the ac/dc converter into the backup secondary battery, and a control circuit for opening and closing a current path for supplying an output current of the backup secondary battery to the load circuit.

A laser scanning optical microscope comprises a first optical scanning device for generating a laser beam and scanning a specimen with the laser beam in a direction at a preselected frequency. A drive circuit controls the first optical scanning device to scan the specimen with the laser beam. A pair of second optical scanning devices scan the laser beam in directions perpendicular and parallel to the scanning direction of the first optical scanning device at two frequencies lower than the preselected frequency. A light receiving device receives light reflected or transmitted by the scanned specimen and produces a photoelectric signal. A signal processing device converts the photoelectric signal obtained from the light receiving device to a standard television scanning signal corresponding to a laser beam scanning pattern obtained with the first optical scanning device and the pair of second optical scanning devices.

The problem of rusting relating to a magnetic recording medium composed of a non-magnetic base and a magnetic recording layer of a ferromagnetic metal layer formed thereon is overcome by a magnetic recording medium comprising a non-magnetic support, a ferromagnetic metal thin film as a magnetic recording layer and a lubricating layer, wherein the lubricating layer contains a mixture of a first lubricant having a polar perfluoro radial and a second lubricant expressed by the following formula: ##STR1## where R is a divalent radical having 2 or fewer carbons atoms;D is a polar radical selected from phosphorus-containing radical, hydroxyl, carboxyl and esterified carboxyl;R.sup.1 is selected from F, CF.sub.3 and C.sub.2 F.sub.5 ; andR.sup.2 and R.sub.3 are selected from F, CF.sub.3 and C.sub.2 F.sub.5, CF(CF.sub.3).sub.2 and C(CF.sub.3).sub.3.
摘要:
A laser beam emitted by a laser light source is scanned in a series of small, high-speed oscillations in a first scanning direction by an acousto-optical deflector, and scanned at a lower frequency in a second direction perpendicular to the first scanning direction by a vibration mirror galvanometer, and scanned at yet a lower frequency in a third direction, parallel to the first direction, by a mirror galvanometer in order to enable high-precision scanning, and is projected onto a prescribed region of an eye. Light reflected by the eye passes, via the mirror galvanometers and, through a confocal optical aperture and is converted to an electrical signal by a photosensor. The signal is then converted by a signal processor to a standard television line format.

An apparatus for processing video signals which is adapted to a function for superimposing a video signal different from a video signal which is separated into a luminance signal and chromatic signal on the video signal is disclosed. The video signal processing circuit includes a first input terminal for inputting the video signal which is separated into the luminance signal and chromatic signal, a second input terminal to which the video signal is inputted as a composite signal, and a third input terminal to which an image signal different from the video signal is inputted, and a control circuit for switching the input signal from the third input terminal so as to superimpose the input signal from the third input terminal on the input signal from the second input terminal.

A first external storage device which may be a CD stores data representing standard map of a particular area and that required for guidance, and a second external storage device which may be an IC card stores individual data which cannot be complemented by said data representing the standard map and said guidance data. Since the data is stored in both CD and IC card, the number of data can be reduced. This makes the operation simpler and enables a data that meets the demand of a user to be selectively supplied to the user. In consequence, guided navigation is made possible from any starting point to a destination, and data updating can be made relatively easy.
摘要:
A ring-shaped member supplying apparatus including a storage section for storing a large number of flexible ring-shaped members stacked in layers and supporting the ring-shaped members so that the lowermost one of the stacked ring-shaped members is held by plural engaging members. A takeout device is provided for drawing out the lowermost one of the stacked ring-shaped members in the storage section, by suction, so as to separate the ring-shaped member from the remaining members and transferring the ring-shaped member to a conveying passage. A detecting device is provided for detecting an amount of the stacked ring-shaped members in the storage section. A supplementing supply is provided for replenishing an amount of the ring-shaped members in response to a decrease in an amount of the ring-shaped members in the storage section so that the amount of the ring-shaped members in the storage section is controlled to be in a predetermined range.
