Patent JP-S6390034-A (JP)
Title: Tracking control device
Inventor: KONNO YOSHIKIYO
IPC: G11B7/09
Filed: 1986-10-01
Abstract: PURPOSE:To efficiently suppress heat generation noise by providing the titled device with a detector for detecting the level of a signal with almost twice the frequency of an added signal obtained by adding the outputs of a pair of detectors and automatically controlling the outputs of the pair of detectors in accordance with the output of the detector. CONSTITUTION:A pair of detectors 1, 2 detect the deflection of an information detecting point in a direction rectangular to a track and a differential amplifier 7 forms a tracking error signal from the difference between the outputs of the detectors 1, 2. In accordance with the tracking error signal, an actuator 11 deflects the relative position of the information detecting point to the track in the direction rectangular to the track. A generating circuit 12 generates an adding signal to add the adding signal to the tracking error signal by an adder 8 and the added signal is sent to the actuator 11 through an equalizer 9. An adder 21 adds the outputs of the detectors 1, 2, a detector 23 detects a signal level with almost twice the frequency of that of the adding signal from the output of the adder 21 and automatic gain controllers 5, 6 control the outputs of the detectors 1, 2.

Title: Reserve exciting circuit for engine generator
Inventor: NONAKA MASAAKI
IPC: H02P9/08
Filed: 1990-09-05
Abstract: PURPOSE:To effectively avoid a defect for starting failure by forming a circuit for supplying a reserve exciting current to a generator field winding from a predetermined voltage source provided separately when a self-excited type generator is started. CONSTITUTION:A previously excited battery 23 is provided as a predetermined voltage source, and an exciting current is supplied to a field winding 2F through a reserve exciting circuit 21. That is, since a start switch 21A in the circuit 21 is closed in cooperation with generation of a start command to this engine generator, a reserve exciting current flows from the battery 23 through a limiting resistor 21B, and hence the output voltage of the generator is rapidly raised upon rising of a speed irrespective of the amplitude of the residual voltage. When a voltage detector 13 detects that the output voltage of the generator reaches a predetermined value, a relay 22 is operated. As a result, a breaking contact 22A is opened in cooperation with the relay 22 to interrupt the exciting current, and a clutch disengaging contact 22B is also opened to separate a self-starter motor 5 from an engine 3.

Abstract: PURPOSE:To enable reduction of production of NOx, by a method wherein a flame dispersion type nozzle is so formed as to be axially movable, and revolving vanes are mounted on the outer periphery of the nozzle, and a damper, regulating a ratio between primary and secondary air, is provided. CONSTITUTION:A radiant tube burner is axially moved within a set position L of a flame dispersion type nozzle 3 in a range of 100-500mm, and by fixing the burner by means of a set bolt 16, a combustion amount in primary combustion can be regulated and fixed. By regulating a ratio between primary and secondary air by means of a combustion air regulating damper 7, an NOx production amount can bring the burner into an optimum combustion state. Revolving vanes 10 are mounted on the nozzle 3 to generate a swirl flow, and this constitution enables a difference between a maximum and a minimum temperature to be adjusted in a range within 10 deg.C and 150 deg.C in a peripheral and an axial direction respectively in relation to the temperature of a tube. Since a maximum tube temperature at a time when temperature in a furnace is 950 deg.C is 1,050 deg.C or less, the life of the radiant tube can be increased to a value durable to a long-term use.
