Title: Optical transmitter
Inventor: ATOZAWA MIZUMASA
IPC: H04B10/293
Filed: 1994-12-02
Abstract: PURPOSE: To obtain an optical transmitter in which no optical surge is generated when an input optical signal to a rare-earth doped fiber is interrupted. CONSTITUTION: A signal interruption detection circuit 31 monitors interruption of a data signal 12 and a clock signal 13 and provides an output of an interruption detection signal 32 till after a prescribed time longer than a mean life time of an excitation level carrier of an erbium doped optical fiber 15 when either or the both are interrupted. While the signal 32 is outputted, an output control circuit 25 stops the supply of an excitation light. Furthermore, while the interruption detection signal 32 is outputted, the output operation of an optical signal by an electric/optic signal converter 11 is stopped. Thus, since the amplification of the optical signal is restarted after the energy of the carrier is sufficiently decreased through spontaneous discharge, no optical surge is generated.

Title: Power inverter circuit and ignition circuit
Inventor: SUZUKI TOSHIYASU
IPC: H02M3/28
Filed: 1988-11-29
Abstract: PURPOSE:To simplify an ignition circuit structure by connecting a coil with a saturating characteristic in its flux and a switching means with a saturating characteristic in its main current in series between both output terminals of direct current power so as to obtain a self-generating type power inverter circuit without needing feedback winding. CONSTITUTION:As the electric current of a coil 9 is zero at first in a DC-AC inverter circuit, a transistor Tr5 is turned on together with a transistor Tr2, so that a current starts flowing to a load resistance 10 and the coil 9. When the flux of the coil 9 is saturated, the current of the coil 9 is suddenly increased accompanied by the sudden decrease of the inductance. However, as the Tr5 does not accept the current over the saturation current value determined by the base current and its amplification factor, the excess coil current flows passing through a resistance 7 and a diode 6, or the load resistance 10. As a result, the Tr2, Tr5 are turned off. Afterwards, when the current of the diode 6 is cut off, the Tr2, Tr5 are turned on again, and the circuit is thus generated in the same repetition hereinafter.

Title: Voice input oa system
Inventor: OOKATA HIROFUMI
IPC: G10L15/00
Filed: 1987-11-30
Abstract: PURPOSE:To input and operate data through voice by connecting plural I/O interfaces through a network. CONSTITUTION:When a command and data based upon voice are inputted from an I/O interface part 1-k (k=1-n), a 1st voice processing part 2-k recognizes the command, converts the command into control data and outputs the converted data to a network 3. On the other hand, the data based upon the voice are preprocessed by the voice processing part 2-k or directly outputted to the network 3 as it is through the voice processing part 2-k. A control command controls the operation of a central processing part 5 through a 2nd voice processing part 4. On the other hand, the data based upon voice are converted into numerically expressed data by the voice processing part 4 and processed by the central processing part 5 in accordance with the control command. Since plural I/O interface parts use one processing part in common, cost increase can be suppressed.

Title: Turntable device for disk player
Inventor: AOKI TAKESHI
IPC: G11B17/028
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a device facilitating the loading/unloading operation of a disk by providing a disk holding member and a turntable to which the urethane coating is applied on the disk placing surface. SOLUTION: A bearing 8 is in the state being pressed outward, i.e., in the direction of the arrow A, taking a rotary shaft 2 as a center by the elastic force of a spring 9. In this case, the displacing force to the direction of the arrow A of the bearing 8 is exerted on a corner part D1 on the inner wall of a center hole formed on the disk D. Thus, the force pressing the disk D onto the placing part 5 of the turntable 4 is exerted thereon. As the result of the exertion of such a force, the disk D is rotated with the turntable 4 by the frictional force between the disk placing surface 5A coated with urethane and the lower surface of the disk D. Consequently, the disk D is rotatable by the rotation driving operation of the turntable 4 in company with the rotational operation of a motor 1.
