Abstract: A television system which selectively receives additional information multiplexed in a video-signal source different from and other than a video-signal source currently being watched. A video signal V7 supplied to a CCD/EDS data extractor 7 is selected independently of a video signal V5 for a main screen of a CRT 10 or a video signal V6 for an auxiliary screen of the CRT 10 displayed by a PinP (PoutP) function. Accordingly, captions to be displayed are not limited to additional information multiplexed in the video signal V5 for the main screen displayed on the CRT 10. As a result, additional information multiplexed in a video signal for the auxiliary screen other than that for the main screen or multiplexed in an external video signal V2 can also be displayed as well.

Abstract: A spread spectrum communication system for performing spread spectrum communication by superimposing a pseudo noise signal on a transmitted signal. The system comprises traffic detecting means for detecting the traffic of the transmitted signal, and means for changing the clock frequency of the pseudo noise signal in accordance with the output from the traffic detecting means. The system may alternatively comprise transmission quality determining means for determining the transmission quality of the received signal, and means for changing the clock frequency of the pseudo noise signal in accordance with the transmission quality determined by the transmission quality determining means. In operation, the system offers improved S/N ratios where traffic is high or transmission quality is low, saves power where traffic is low or transmission quality is high and ensures large margins of power control precision for mobile stations near the upper limit of the system's line capacity.

Abstract: A variable magnification finder wherein a change in magnification is performed by rotating the finder about an axis. According to a first embodiment of this invention, a variable magnification finder has in succession from an object side a first lens component including a four-surface lens, a second lens component having a convex surface facing the object side and a third lens component having a convex surface facing the object side. The four-surface lens includes a first surface opposite a second surface and a third surface opposite a fourth surface. The first and second surfaces have a first optical axis in common and the third and fourth surfaces have a second optical axis in common. The first optical axis is substantially perpendicular to the second optical axis. Magnification of the finder is changed by rotating the four-surface lens on a third optical axis which is substantially perpendicular the first and second optical axes.

Abstract: A method and apparatus for creating an optical disk mother or stamper wherein the number of processing steps is greatly reduced from the prior art methods. In particular, the present invention involves directly forming a mother or stamper by direct laser ablation of a conductive metal substrate. More specifically, a stream of coded digital information (for example, representing the content of an encyclopedia in the case of CD ROM or a classical music collection in the case of CD audio) is converted into a corresponding plurality of pits and lands in the conductive metal substrate by electronically switching the beam of a first laser on and off via an electro or acusto-optic modulator (EOM/AOM) in response to the digital information. As a result, selective portions of the conductive substrate are either ablated (in the case where the laser is on) thereby directly creating the pits, or the substrate is left unaltered (in the case where the laser is off) thereby creating lands.

The heat-resistant lubricating layer is made of either a polymer compound obtained by reaction between a hydrocarbon compound having at least two hydroxyl groups in one molecule and/or a silicone compound having a hydroxyl group and an isocyanate compound having at least two isocyanate groups in one molecule, or a polymer compound obtained by reaction between a silicone compound having an amino group and an isocyanate compound having at least two isocyanate groups in one molecule.

Abstract: A semiconductor deposition and oxidation process using a single furnace cycle. The temperature and gas mixture is stabilized inside the furnace prior to introduction of a dopant at a relatively low temperature. The temperature of the chamber is then ramped-up and the dopant is diffused into the wafer in an inert ambient. The temperature is then ramped-up again and oxygen is introduced to produce an oxide layer. The wafers are then removed from the furnace and any residue of the dopant within the chamber is effectively neutralized by introducing a high flow of oxygen.

The groups and any remote control signals existing within the group are stored in order of priority.

Abstract: A variable gain differential amplifier using a single operational amplifier. A potentiometer is used in the negative feedback loop with one end connected to ground through a resistor which limits the maximum gain. The other end is connected to the output and the wiper is connected through a minimum gain limiting resistor to the inverting terminal. This provides an amplifier with good CMRR, relatively low input impedance, wide gain control and variability with a single operational amplifier.

Abstract: A demagnetizer for display unit which allows to reliably demagnetize without bothering the user thereof. A start pulse a1 is sent out from a timer 21 to an activating pulse generating circuit 22 in every predetermined time t1 to sent out an activating pulse b. Receiving the activating pulse b, a demagnetizing current generating circuit 23 sends out a demagnetizing current I to a degauss coil 1 to demagnetize a magnetized shadow mask (or aperture grille). The activating pulse b is also supplied to a reset pulse generating circuit 24 to send out a reset pulse c to the timer 21. Thereby a counting of the timer 21 is reset and the start pulse a1 is sent out as the predetermined time t1 elapses. This demagnetizer allows to carry out the demagnetizing action without bothering the user.
