Title: Digital vsb modulating device
Inventor: ISHIKAWA TATSUYA
IPC: H03C1/60
Filed: 1991-02-08
Abstract: PURPOSE:To simplify and miniaturize the constitution by generating a low-band DSB (double sideband) modulation signal and a high-band SSB (single sideband) modulation signal from a digitized base band signal and adding both modulation signals to obtain a VSB (vestigial sideband) modulation signal. CONSTITUTION:The base band signal supplied to an input terminal 11 is distributed into two by a distributing circuit 12, and one output has the low band component extracted by an LPF 13. The output of this LPF 13 is distributed into two by a distributing circuit 14, and one is supplied to a subtracting circuit 15. The other output of the distributing circuit 14 is supplied to the circuit 15, and the high-band component of the base band signal is extracted. This base band signal is supplied to an SSB modulation circuit 18 through multiplying circuits 17 and 39 to obtain the DSB modulation signal. The other output of the circuit 14 passes multiplying circuits 26 and 28 and an adding circuit 27 to obtain the DSB modulation signal. The DSB modulation signal and the SSB modulation signal are added by an adding circuit 29 to generate the VSB modulation signal of the frequency spectrum.

Inventor: NOGUCHI JUNICHI
IPC: B29K105/08
Filed: 1994-02-15
Abstract: PURPOSE:To provide a fiber reinforced connecting rod of excellent durability. CONSTITUTION:A second fiber layer 10 is laminated on the end face of the rod part 5 and the large end part 6 on the base end side of a connecting rod main body part 1 in which a first fiber layer is laminated, so as to form an outer layer part 3, and a third fiber 14 is wound along the direction meeting at nearly right angles with the longitudinal direction of the first fiber and the second fiber on the extreme end part of the rod part 5, so as to form a joint part 4. By crossing the directions of the fiber of the connecting rod main body part 1 and the outer layer part 3 and the fiber of the joint part 4 perpendicularly to each other, even if the resin of the connecting rod main body part 1 and the outer layer part 3 is expanded, the extreme end part of the rod part 5 becomes in the condition of being relatively tightened with the third fiber, interlayer separation is not generated in the second fiber layer of the outer layer part 3, interlayer separation of the outer layer part 3 due to compressive load is prevented, and hence a fiber reinforced connecting rod 1 of excellent durability is provided.

Abstract: PROBLEM TO BE SOLVED: To make it possible to install a chuck in proximity to a planar part without the interference with a cover for recovering a waste liquid by executing the holding and releasing of the planar part by rotation of a chuck pin around the central axis of the chuck pin as an axial center. SOLUTION: A wafer supporting section 200 comprises the chuck pin 201 with a gear 202, an outer ring 203, an inner ring 204 with a gear 205, a pin retainer 206, a coupling pin 207 and an outer ring hood 208. The chuck pin 201 is held by a groove inscribed on the inner side of the outer ring 203 and the outside surface of the inner ring 204. The gear 202 on the outer periphery of the chuck pin 201 and the gear 205 disposed on the outside surface of the inner ring 204 fit to each other. The chuck pin 201, therefore, makes rotation motion by the relative rotation of the outer ring 203 and the inner ring 204 and makes revolution motion accompanying the rotation of the outer ring 203.  The peripheral part of a wafer 1 is consequently pressed by the inscribing of a V shape accompanying the swiveling of the chuck pin 201 and when the chuck pin swirls 90 deg., the wafer 1 is held by the chuck pin 201.

Abstract: PROBLEM TO BE SOLVED: To provide a counter station alarm monitor transmission system in which a transmitter fault state of a specific transmitter is monitored by a counter station side equipment even on the occurrence of the fault at the transmitter side of the specific transmitter. SOLUTION: In this system, an alarm monitor 12' always monitors transmitters 131 '-13n ' based on incoming alarm state signals DU1 from them. On the occurrence of a transmitter side fault in a specific transmitter, the alarm monitor 12' sends a transmitter side fault state signal DU4 to each transmitter of the monitor object as an outgoing signal. Each transmitter adds the outgoing transmitter side fault state signal DD4 to a main signal as overhead bits and sends the resulting signal to counter station side equipments.  The counter station side equipments other than that opposite to the transmitter side faulty transmitter extract the transmitter side fault state signal DD4 and outputs it as an incoming transmitter side fault state signal DD4 to the alarm monitor 12' and the alarm monitor 12' monitors the incoming transmitter side fault state signal from each transmitter to recognize the transmitter side fault of the counter station.

Abstract: PURPOSE:To obtain the optimum pattern by changing a magnetizing current for a magnetizing pattern in an approximately trapezoital shape, or forming the length of a leading unit magnet in the direction of a track at 30 - 90% the length of other unit. CONSTITUTION:Each unit magnet 8 is arranged on an REF1 track 2 and an REF2 track 6 for a detecting reference signal of an REF signal. The lengths (magnetizing pitches) of a leading unit magnet 9 and a final unit magnet 7 are made shorter than an ordinary length. The magnet having such a length is shown. A non-magnetized part 10 is formed. As the appropriate combination of the magnetizing pitches, it is suitable that the lengths of the magnets 7 and 9 are 30 - 90% the length of the magnet at the central part, and preferably about 60% is optimum. The first pulse is applied to the leading magnet 8. The magnet 7 is formed with the next polarity-inverted pulse. The same magnetization is performed with a magnetizing waveform. The magnetizing waveform 11 in the REF1 is formed as follows. The width of the pulse time is shortened at the same time with a slight delay between the time when the leading magnet 9 is formed and the time when the magnet 7 is formed. The waveforms are sequentially formed, and the optimum pattern is obtained.
