Title: Reversible current chopper
Inventor: KARUBE KUNIHIKO
IPC: H02M3/155
Filed: 1988-02-02
Abstract: PURPOSE:To reduce snubber loss, by constituting a snubber circuit only with capacitors. CONSTITUTION:A reversible current chopper comprises first and second switching elements, i.e., transistors 18, 19, a current smoothing circuit 14 comprising a smoothing reactor 12 and a capacitor 13, a control section 20 and the like, where power is fed from a power source 9 to a rotary machine 15 in order to operate the rotary machine 15 as a motor. A FET18 comprises a switching element, i.e., a body section 18a, and a parasitic diode 18b, and a FET19 is constituted similarly. The control section 20 outputs first and second control signals 21, 22 and performs ON/OFF control of FET body sections 18a, 19a. The FET's 18, 19 are provided in parallel with snubber capacitors 23, 24 and connected with the current smoothing circuit 14. Since a DC power source 9 is not shortcircuited through circulation diodes 18b, 19b, turn-off loss is reduced.

IPC: G11B7/005
Filed: 1993-02-10
Abstract: PURPOSE:To optimize recording conditions by detecting position shifts in the binary signals of reproduced data obtained from evaluation patterns, analyzing the position shifts and detecting fluctuation in binary signals which are generated during a recording and reproducing process. CONSTITUTION:A detection window width Tw is used as a reference for a pulse width. The leading pulse width is 3/2 Tw and in order record 3Tw, a recording waveform in which Tw/2 pulses are successively connected with Tw/2 gaps is used. Moreover, in order to record 3Tw, pulses are set to the power and pulse width which are the values used record previous 2Tw, and a recording power is again irradiated with a Tw/2 width, through a preheat level with a Tw/2 width. Moreover, as a mark length is stretched for every Tw, a gap section and a pulse section are made into one combination and a recording is performed using the waveform to which one combination is added as Tw increases. Thus, how the amount of the maximum edge position shift varies against the change in fluctuation parameters which are generated during a recording and reproducing process is evaluated.

IPC: H04B3/36
Filed: 1979-03-01
Abstract: PURPOSE:To reduce the cost through the selection to the spare transmission line at the selective station at the both ends of set section, in the selection to the spare transmission line. CONSTITUTION:Stations B, C are merely passing stations, and relay transmission is made with the relay transmission unit 6BX because the transmission line is not connected to the selector switch at station B, and relay transmission is made at the station C with the relay transmission unit 6CX. Since the station in which the transmission line X is connected to the selector switch is A and D station, the transmission line X is selected to the spare transmission line S between the stations A and D. If the transmission termination station 4AX detects a failure, signal is transmitted to the selective control station 3A and the failure transmission number X is fed to the station D via the stations B and C. The selective control unit 3D of the station D selects the selector switches 2D and 2A simultaneously with the selection control unit 3A to select the transmission line X to the spare transmission line S.

Filed: 1990-02-01
Abstract: PURPOSE:To provide the reader splicer capable of developing a film efficiently without preprocessing for leading a film leader out by rotating a spool in the feed direction and sending the film leader out of a cartridge main body automatically. CONSTITUTION:When the start key of a keyboard 16 is operated, a controller 27 turns on a film leader part 51 after a reader is set. Consequently, a shift part 57 is driven to insert a spool rotation shaft 55 into the shaft end of the spool 42, and then the spool rotation shaft 55 is rotated in the film feed direction. A negative film 41 is prevented by a pressure piece 44 from being unwound, so the rotation of the spool 42 is transmitted to the film leader part 45, so that the film leader part 45 is sent out of a film lead-out slit 46 along the inner peripheral surface of the cartridge main body 43. Then the film leader part 45 is nipped by a 1st feed roller couple 76 by the rotation of 1st and 2nd feed roller couples 76 and 80.

Title: Digital radio equipment
Inventor: KATOU KAZUMORI
IPC: H04B7/04
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To make a digital radio equipment small in size and low in manufacturing cost by constituting the radio equipment without using a shared unit by switching the output of transmission part and the input of a receiving part at antenna side and switching the diversity reception to the non-diversity reception at plural slot communication. SOLUTION: In two-slot communication, an antenna 1 is exclusively used for transmission when the system transmits from a radio terminal station to a base section. Namely, it enables execution of two-slot transmission by switching a switching device 3 to transmission side. Through receiving operation, an arrived signal wave is inputted from an antenna 2 and inputted to a second receive part 11 via a receive filter 18. The second receive part 11 performs high-frequency amplification of the inputted signal, converts the signal into an intermediate frequency, and sends it to a second demodulation part 12'. The second demodulation part 12' detects the inputted signal. A control part 17' switches over diversity action to non-acting state, since the signal is not inputted to a first receive part 9 when the two slot communication is performed.
