Title: Optical output control system
Inventor: YAMADA KIYOHISA
IPC: H04B10/00
Filed: 1990-10-19
Abstract: PURPOSE:To prevent light signals from impinging on eyes by a method wherein a light emitting element outputs light signals only when an optical fiber is connected to an optical output connector. CONSTITUTION:Electrically insulated conductors 6 and 7 are mounted on an output connector 5, and when a terminal 4 fixed to an optical fiber used for taking out light signals is connected to an optical connector 5, the conductors 6 and 7 become electrically conductive, and in result optical fiber connection detection signals 8 and 9 are outputted. On the other hand, a drive circuit 2 outputs a drive signal 3 which drives a light emitting element 1 that converts the inputted electrical signals into optical signals only when the optical fiber connection detection signals 8 and 9 are inputted.

Title: Torque control device for dc machine and torque measuring device for dc machine
Inventor: TSUNODA KOZO
IPC: H02P7/292
Filed: 1994-11-15
Abstract: PURPOSE: To stabilize torque control during a low rotating speed by providing a comparator and a transfer switch to be controlled by the comparator. CONSTITUTION: A comparator 21 outputs only when a rotating speed value connected to F/V converter 12 is 0 to 5%. A transfer switch 22 is switched by the output from the comparator 21. Where there is no output from the comparator 21, an electric arithmetic torque T from a divider 13 is input to a torque control amplifier 16, and an armature current Ia from a rectified 7 output from the comparator 21 is input to the torque control amplifier 16. By doing this, if a DC machine 2 has a speed lower than 5% of the rated speed, then the comparator 21 outputs, a switch 22 is switched, and the armature current Ia from a rectifier 7 is input to detection side terminals of the torque control amplifier 16. Therefore, the torque control amplifier 16 performs the torque control of the DC machine based on the torque detection of the armature current Ia.

Title: Controller for electric motor car
Inventor: TADA SEIJI
IPC: H02P27/06
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To enable torque control by inputting the motor car speed information corresponding to a motor car speed of one of a train monitor, an automatic train controller, a motor car speed detector, etc., to a change-over device, and performing changeover at the start of an inverter. SOLUTION: A primary interlinkage flux vector is computed for compensating voltage information v by an amount corresponding to a voltage drop caused by the resistance of a primary coil, and a real torque is obtained by the vector product of a primary interlinkage flux and a primary current. Along with obtaining a secondary interlinkage flux from the primary interlinkage flux and the primary current, a secondary angular frequency ω2 is found, and a slippage angular frequency ωs is obtained from the values of the secondary interlinakge flux, the real torque, and the resistance of a secondary coil.  Although a change-over device 17 selects a signal ωm which is the output of the motor speed information 18 of a train monitor, etc., in place of a signal ωm' which is the output of a torque control unit 16 in a specified period after starting, the change-over device 17 performs changeover so as to select the computed value ωm' of the angular frequency of a rotor by detecting that the error between ωm and ωm' became equal to or lower than a value set beforehand. Consequently, it becomes possible to perform torque control at the start time as well.

Title: Production of optical recording medium
Inventor: MOTOMIYA KAZUOKI
IPC: G11B11/10
Filed: 1988-11-07
Abstract: PURPOSE:To shorten the time for operations and to save energy by irradiating a substrate consisting of org. matter with an electron beam while evacuating the inside of a vacuum vessel. CONSTITUTION:The substrate 1 consisting of the org. matter is irradiated with the electron beam in the vacuum film forming device to release the gases incorporated in the substrate before the formation of a protective film and recording film on the substrate 1 at the time of forming the protective film and the recording film on the substrate by the above-mentioned device. For example, the batch-operated sputtering device provided with the substrate 1 consisting of org. matter, such as polycarbonate, an electron beam source 2 for irradiating the substrate 1 with the electron beam, a target 3, a discharge pump 4, and a substrate holder 5 holding the substrate 1 while rotating the same is used. Since electron is much smaller in mass and size than atom and, therefore, the influence on the structure and compsn. of the org. matter is small even if the org. matter is irradiated with a large quantity of the electrons as a beam. The gases in the substrate are released with the smaller energy for a short period of time and the recording medium having good characteristics is obtd.

Abstract: PURPOSE:To distinguish reproduced signals of high density recording with fidelity by adding a time reference signal (synchronizing signal) to recording signals at the time of magnetic recording, and oscillating a variable frequency oscillating circuit (VFO circuit) by reproducing synchronizing signal voltage. CONSTITUTION:Recording signals 1 are inputted to a modulating circuit 2 in a recording circuit, and time compressed information signals 3 and synchronizing signals 4 utilized for a VFO circuit are generated.
