Abstract:
A communication system is capable of two-way wireless data communications between a parent unit and a child unit. The child unit includes a power switch for turning power to the child unit on/off; a power control signal issuing unit operable to issue a power control signal for turning power to the parent unit on/off in response to turning the power switch on/off; and a data communication unit operable to perform two-way wireless data communications with the parent unit. The parent unit includes a power control signal receiving unit operable to receive the power control signal from the issuing unit of the child unit; a power control unit operable to turn power to the parent unit on/off in response to reception of the power control signal from the receiving unit; and a data communication unit operable to perform two-way wireless data communications with the child unit.
Abstract:
A digital signal transmitting method, a digital signal receiving apparatus, and a recording medium which ensure the security of fee-charged software information. When an image providing predetermined services is transmitted, a band-compression coded digital video signal is given first-encryption processing and then the digital signal is further given encryption processing and transmitted. Therefore, double security can be added to the video signal and a digital signal transmitting method where its security is more firmly ensured can be realized.
Abstract:
A seal plate 8 is located between the outer ring 1 and inner ring 3, and the outer diameter 11 side of the this seal plate 8 is fastened to the stationary ring 1, and the lip 13 an the inner-diameter 12 side comes into sliding contact with or keeps a clearance with respect to the inner ring 3 to secure seal performance, and there is a protruding section 19 formed on the side surface 18 on the outside of the seal plate 8, so that a clearance 29 is formed between the protruding section 19 and the peripheral part 25 near the bearing. Consequently, it is possible to provide a sealed-type rolling bearing where the seal performance is improved without increasing cost, by providing not only sealing in the lip portion but also sealing between the bearing and the peripheral part near the bearing.
Abstract:
An apparatus and method for transferring from a broadcaster to a receiver a limited reproduction right in data. A signal indicating the limited reproduction right is transmitted by the broadcaster and stored by the receiver with the data. The receiver reproduces and processes the data as a function of this signal.

Abstract:
A graphite-free lubricating oil which comprises a base oil having dispersed therein 10 to 40% by weight of a carbohydrate and/or a derivative thereof whose particle size ranges from 10 to 150 .mu.m, 2 to 20% by weight of a film-boosting agent and 0.1 to 20% by weight of a dispersant. Moreover, the lubricating oil is free of black-colored substances such as graphite. Therefore, the oil permits the improvement of working surroundings and exhibits excellent properties such as formability through forging almost comparable to or even greater than that of the commercially available graphite-in-oil type lubricating oils. The lubricating oil can be used instead of the graphite-containing lubricating oils for warm forging, hot forging, rolling, tube-manufacturing, drawing and extrusion in place of the graphite-containing lubricating oils and ensures the improvement in the working surroundings and excellent lubricity.
Abstract:
A sealed rolling bearing including inner and outer races and a pair of sealing plates in which fixing grooves each for fixedly receiving a fixing edge portion of a corresponding sealing plate are formed in the edge portions of the peripheral surface of one of the inner and outer races, and slide grooves each for slidably receiving a slidable seal edge portion of a corresponding one of the sealing plates are formed in the edge portions of the peripheral surface of the other race. Each slide groove has a U-shaped cross-section including a bottom surface and a pair of axially outward and inward inclined surfaces. Each sealing plate comprises a core and a flexible seal member integrally fixed to the core, and first, second and third lips which extend axially outwardly, axially inwardly and substantially radially, respectively are formed on the slidable seal edge portion of each sealing plate. The first lip is slidably abutted against a peripheral surface contiguous to the axially outward inclinded surface of the corresponding slide groove, the second lip is slidably abutted against the axially inward inclined surface, and the third lip confronts the bottom surface with a slight clearance.
Abstract:
In an apparatus for recording a video signal on a record medium and having a circuit for separating luminance and chrominance signal components from an input video signal, a frequency-modulator receiving the separated luminance signal component and providing a frequency-modulated luminance signal, and an emphasizer low frequency components of the frequency-modulated luminance signal; a circuit is provided for selecting, as the luminance signal to be recorded on the record medium, either the frequency-modulated luminance signal from the frequency modulator when the video signal is derived from a television tuner or video reproducing apparatus having a relatively large frequency band, or the low frequency emphasized output of the equalizer when the video signal is from a television camera having a relatively smaller frequency band.
Abstract:
A steam turbine plant of one embodiment includes a boiler to change water into steam, a high pressure turbine including plural stages of rotor and stator vanes and to be driven by the steam from the boiler, a reheater to heat the steam from the high pressure turbine, a reheat turbine including plural stages of rotor and stator vanes and to be driven by the steam from the reheater, a condenser to change the steam from the reheat turbine into water, a collector to collect water from, for example, the steam existing upstream of an inlet of the final-stage rotor vane in the high pressure turbine, and a path to cause collected matter in the collector to flow into, for example, the steam between an outlet of the final-stage rotor vane of the high pressure turbine and an inlet of the final-stage rotor vane of the reheat turbine.
