Title: Amplifying circuit
Inventor: KOBAYASHI OSAMU
IPC: H03F3/345
Filed: 1989-11-10
Abstract: PURPOSE:To release an excess input quickly, to quicken the operation and to protect the circuit by setting an output current of 2nd and 3rd amplifier stages to a prescribed ratio and controlling an output of a 1st amplifier stage with a feedback circuit when a level of a connecting point is at a prescribed value or over or below. CONSTITUTION:An output signal of amplifier stages 12, 14 is obtained as a current and the output currents of the amplifiers have a prescribed ratio, and a voltage at a node N being a connecting point between the amplifier stage 14 and a constant current source 18 depends on a difference between the output current of the amplifier stage 14 and the current of a constant current source 1. The voltage of the node N is fed back to an amplifier stage 10 through a feedback circuit 16 and the feedback circuit controls the amplifier stage 14 only when the the voltage is high or low. Thus, excess input is restored quickly, the operation is quickened and the circuit is protected.

A meter processing part 13 calculates phoneme parameters such as duration of phoneme, pitch outline, energy outline, pause position, length, etc. A synchronization adjuster 14 adjusts the duration of each phoneme by using the synchronizing information sent from a multiple medium distributor 11 in order to synchronize synthesized sound with moving picture.  The adjusted information is transmitted to a signal processing part 15, and selects necessary data for synthesis from a synthesis unit data base 1, and refers the data to the phoneme information for correction, and then, generates synthesized sound for outputting it.

Title: Optical spectrum analyzer
Inventor: KOMIYAMA MAKOTO
IPC: G01J3/18
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To enable high-speed measurement in a compact and inexpensive constitution by fixing a diffraction grating and rotating a scanning mirror smaller than the diffraction grating. SOLUTION: An incident light 100 turned to a parallel light by a collimator mirror 1 is diffracted by a diffraction grating 2a to an angle corresponding to a wavelength. The light diffracted for every wavelength is turned to a converging light at a condensing mirror 3 and brought into a slit 5 through a scanning mirror 12. At this time, the diffracted light condensed on the slit 5 differs in condensation position by the wavelength, and therefore there are some diffracted light detected at a photodetector 6 passing through the slit 5 and the other shut by the slit 5 not to enter the photodetector 6. The diffraction grating 2a is fixed with a constant angle, while the scanning mirror 12 is rotated to change the condensation position on the slit 5, so that the diffracted light of a specific wavelength is brought to the photodetector 6 selectively.  A wavelength and an intensity of the incident light 100 are detected from a rotational angle of the scanning mirror 12 and an output signal of the photodetector 6 (intensity of the diffracted light).

Filed: 1986-12-10
Abstract: PURPOSE:To obtain a disk cleaner device that can secure the even cleaning effects at both of inner and outer circumferential parts of a disk, by increasing the disk surface pressing force of a cleaning member toward the inner circumference of the disk to execute a disk cheaning job. CONSTITUTION:A cleaner 18 which is guide by a guide member 31 gets close to the disk surface at the inner circumferential part of a disk 15 and moves away from the disk surface at the outer circumferential part. Thus a coil spring 20 contracts more toward the inner circumference of the disk and extends more at the outer circumference respectively. As a result, the disk pressing force is increased at the inner circumference and reduced at the outer circumference of the disk respectively. Then the produce of the relative speed of the cleaner 18 to the disk and the disk pressing force is kept at an approximately constant value between the inner and outer circumferences of the disk to indicate the cleaning effect. In such a way, the even and high-performance cleaning effect is secured and at the same time the disk pressing force varies between the inner and outer circumference of the disk so that the servo control of a turntable 14 is not affected. Then the servo stability of the table 14 is attained.
