Abstract: A management apparatus in a time synchronization system includes a time variation information receiving unit configured to acquire time variation information and position information of a time synchronization apparatus, a position information classifying unit configured to classify time synchronization apparatuses into predetermined categories based on the acquired position information, a time variation analysis configured to determine majority based on whether patterns of time variation of the time synchronization apparatuses belonging to an identical category are identical to each other, and to analyze the time variation based on the determined results, and a filtering and delivery unit configured to output an instruction to block the time information received from the positioning satellite, to the time synchronization apparatus having abnormal time variation.

Abstract: To control the erection of a penis 10, the male sex organ, as desired, an electromagnetic valve 18 is connected to a penile vein 17 of the penis 10, the male sex organ, and ON-OFF control of this electromagnetic valve 18 is performed by a control unit 42 embedded in the body in the vicinity of the penis 10. When an external signal is supplied by a commander 54, the control unit 42 closes the electromagnetic valve 18, suppresses outflow of blood from the spongy body 21, 22, and thereby maintains the erection state of the penis 10.

Abstract: Methods and systems are provided for dubbing a digital video signal on a record medium wherein the digital video signal includes variable-length codes arranged in a fixed-length word format. The variable-length codes are separated from the fixed-length word format data. Error codes indicating errors in the separated variable-length codes are provided. The separated variable-length codes together with the error codes are formed into new data blocks having a fixed-length word format and the new data blocks are recorded on a record medium.

Abstract: A method for recovering solvent vapor in a manner which requires less power using an apparatus which is smaller in size, has a longer life, and is capable of being operated without reducing recovering efficiency, including locating an inlet of a suction pipe at a position within the container between the liquid surface of the solvent and an upper edge of the container, wherein the opening of the suction pipe is open downward, and drawing the vapor from the upper surface of the solvent in the container.

Abstract: In a digital video tape recorder which employs discrete cosine transformation and variable length coding for compressing the data to be recorded, the necessity of an additional signal line for transmission of information incidental to the principal data is eliminated, and a processing margin is obtained in track units upon variable speed reproduction and the like. The digital video tape recorder samples an NTSC signal at a ratio of 4:1:1 or 4:2:0, transforms the sample data for each block of 8.times.8 data by DCT, encodes the transformed data into variable length codes so that 30 DCT blocks constitute a buffering unit having a fixed length to compress the data, and segmentally records the video signal obtained by the data compression divisionally in 10 tracks for each frame. In the digital video tape recorder, the frequency of a signal processing clock signal used for data compression is selected to be equal to 192/143 times the frequency of 13.

Abstract: Fuel is pumped and supplied to an injector which injects the fuel in the form of mist. The quantity of fuel injected from the nozzle is regulated by quantity control means. The control means is comprised of a control valve, which is disposed on the injection hole of the injector for controlling the area of the injection hole. When the control valve has sufficient stroke to close the injection hole, the valve serves not only as a control valve, but also as a timing control valve. The movement or stroke of the control valve is accomplished by an actuator which is controlled by electrical control means, for example a microcomputer, to enable a precise injection of fuel and an ideal combustion.

Abstract: A liquid crystal television receiver has a first housing containing a television receiving circuit, a mirror mounted on an upper portion thereof, and a battery for driving the television receiving circuit, a second housing containing a liquid crystal display panel, and a third housing containing a light emitting element. The first, second and third housings are pivotally connected with each other at rear portions thereof, respectively.

Abstract: Fuel is held under high pressure by an accumulator which is connected with injecting nozzles by respective fuel pipes. The fuel pipes are each provided with a timing control valve and a quantity control valve, and these valves are controlled by an electric control apparatus. The control apparatus controls the timing valve in response to the angular position of the engine and controls the quantity control valve in response to the engine load, whereby the injecting nozzle injects the proper quantity of fuel at the proper moment.

Abstract: A structure for mounting a bezel in a watch case through a packing and for mounting a glass in the bezel through a packing. The watch case has an axially extending, inside engaging portion and an annular groove provided in a lower portion of the inside engaging portion, and the bezel has an inside annular groove. Each of the packings is adapted to be engaged with the corresponding annular groove.

Abstract: A solar battery timepiece has a structure of a module, a base plate on the module, a solar battery cell on the base plate, an insulating flexible sheet provided with a print wiring and interposed between the base plate and the solar battery cell, and a dial ring attached to the peripheral edge of the base plate whereby the solar battery timepiece may be made with a reduced thickness, small in size, simple in construction, shock resistant and reliable in operation.

Abstract: A structure for fixing a watchglass of a watch case, which comprises a watchglass fixing member having a ring-shaped recess and a flange formed at an upper portion of said recess, a watchglass having an outer diametric surface formed with an inclined guiding surface below said outer diametric surface, and a synthetic resin ring disposed in said recess of said watchglass fixing member and sandwiched between said recess and said watchglass and having a protrusion formed when said watchglass is press fitted into said synthetic resin ring, said protrusion serving as means for retaining said watchglass in a fixed place.

Abstract: A fixing structure of a back cover for watches without requirement of any jig to attach a back cover to a watch casing. The fixing structure is disclosed which comprises a watch movement, an outer casing for accomodating said watch movement therein and provided with an opening at the lower portion thereof, a back cover engaged with said outer casing, a first flange formed at the side of said movement on said opening and being shorter than the outer diameter of said back cover, a second flange formed at the opposite side of the movement on the opening and being longer than the outer diameter of said back cover, and the diameter of the opening in said second flange being shorter than the outer diameter of said back cover, a peripheral groove formed between both said first and second flanges, and a flexible packing attached to said peripheral groove, whereby said back cover is attached to the inside of said flexible packing from the direction of said first flange.
