Abstract: A remote commander transmits a command signal from a light emitting element controlled by a transmitting integrated circuit to an apparatus to be controlled. A single low voltage battery drives the remote commander, and a booster circuit boosts the low voltage supplied by the battery. The light emitting element and the transmitting integrated circuit are driven by the output voltage from the booster circuit.

Abstract: An apparatus for immobilizing a movable cabinet (1) including an apparatus body (2) capable of being housed in the cabinet and of being drawn out therefrom, a first caster (3) disposed on a rear bottom surface of the cabinet, a second caster (4) disposed on a front bottom surface of the cabinet, and a leg member (5) disposed on a front bottom surface of the cabinet. The total number of the first and second casters is at least three, and by means of these casters, the cabinet is movable with the apparatus body housed therein. In a lower end of the leg member, there is disposed a flat plate (5b) to be brought into contact with a floor surface to establish an areal contact. The leg member is capable of projecting to a position below a lower end of the second caster of the apparatus body housed in the cabinet. By projecting the leg member, the cabinet is retained in a stationary state. The leg member is also capable of retracting to a position above a lower end of the second caster.

Abstract: A method for hydrocracking a heavy fraction oil which comprises cracking a heavy fraction oil in the coexistence of a catalyst and a hydrogen donating solvent such as tetralin while adding a hydrogen-containing gas to the cracking reactor thereby inhibiting the formation of carbonaceous substances and precursors thereof and then hydrogenating the reaction products in the presence of a solid catalyst while adding a hydrogen-containing gas to the hydrogenating reactor thereby to convert the toluene-insoluble carbonaceous substances and precursors thereof to toluene-soluble ones, thus causing no clogging in an apparatus used.

Abstract: A high-density information recording carrier such as an optical disk which is used for recording and/or playing back information carried on a plastic substrate by means of laser beams has an improved protective layer between a recording layer and the plastic substrate. The protective layer is made of inorganic glass made of alkali-free glass containing less than 1 wt % of alkali metal oxides. The resulting optical disk shows improved durability, higher C/N, lower BER and higher film forming rate.

Abstract: A fail-safe laser apparatus includes a laser beam radiation source for emitting a laser beam along an optical axis, a main shutter for intercepting or attenuating the laser beam incident thereon in its closed position, and a safety shutter for completely intercepting the laser beam incident thereon in its closed position. The main shutter is moved to its open position in coagulating the diseased part. A first sensor produces a first signal indicative of the intensity of the laser beam emitted along the optical axis between the radiation source and the main shutter. A second sensor produces a second signal indicative of the intensity of the laser beam emitted along the optical axis between the main shutter and the safety shutter. A detection circuit is responsive to the first and second signals for actuating a safety shutter control means to move the safety shutter to its open position in accordance with the first and second signals.

Abstract: Ophthalmoscopic slit lamp including a slit illumination section, a binocular microscope and a photographing camera. The microscope is mounted on the upper end of a support arm which is swingable about a vertical axis. The camera is also carried by the support arm at a position beneath the microscope so that it does not disturb the operator.

Abstract: Channel programming apparatus is capable of supplying a first video device, such as a video display, and a second video device, such as a video recorder, each with an individually tuned video signal. The apparatus includes first and second tuner circuits providing first and second tuned signals, respectively, first and second video outputs through which the individually tuned signals are applied to the first and second video devices, a connection for applying the second tuned signal to the second video output, a tuner switching device for selectively applying one of the first and second tuned signals to the first video output, a timing device having an unset state and being changeable to a set state in which the timing device produces a timed command at a selected time, and a device for causing the tuner switching device to apply the second tuned signal to the first video output in response to the tuned command.

Abstract: Channel selecting apparatus for use with a signal receiver coupled to a first tuning device and a signal recorder coupled to a second tuning device is operable to tune the first and second tuning devices to preselected channels for receiving broadcast frequencies. In one embodiment, the signal receiver is a television receiver including a video display, and the signal recorder is a video tape recorder (VTR). Selectively operable channel selectors, common to the first and second tuning devices supply channel selector signals to determine the tuning condition of both tuning devices. When the VTR is actuated, a locking circuit locks the second tuning device to the tuning condition determined immediately prior to such actuation regardless of a subsequent difference in the channel selector signals. The locking circuit in the absence of the actuation of the VTR, enables the tuning condition of the second tuning device, as well as that of the first tuning device, to be determined by the channel selector signals.

Abstract: A television system having two independently tuneable, simultaneously operating, channels contains a switching means for simultaneously displaying video from the two channels on a cathode ray tube for permitting comparison therebetween and independent comparative tuning thereof. In one embodiment, video from one of the channels is displayed in the top half of the screen and video from the second channel is displayed in the bottom half of the screen. Synchronizing signals from only one of the channels is used throughout the display in order to avoid disruption in synchronization due to switching back and forth between channels. In another embodiment of the invention, video from one of the sources is displayed in the first half of each horizontal line and video from the second source is displayed in the second half of each horizontal line. Thus, side-by-side comparison can be made of displayed video from the two sources.

A selectively operable channel selector, common to the first and second tuning devices, generates and supplies channel selector signals to the first and second tuning devices to determine the tuning conditon of both devices.

Abstract: A multiple automatic brightness control for a television receiver including a first automatic brightness limiter (ABL) circuit responsive only to relatively long duration changes in brightness-producing current and a second ABL circuit responsive to brightness-producing current changes of shorter duration than the first ABL circuit. Both ABL circuits have threshold levels below which they are not responsive to brightness-producing current changes, but the threshold level of the second ABL circuit is higher than that of the first so that, while the second ABL circuit responds more quickly than the first, it does so only for higher amplitude changes in the brightness-producing current.
