Title: Control method for boiler gas distributing damper
Inventor: TAKEUCHI YUICHI
IPC: F22G5/04
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a control method for a boiler gas distributing damper, in which the simplification of constitution of the device as well as the reduction of boiler plant cost are contrived by making an economizer outlet port damper unnecessary and the accurate control of a steam temperature at the outlet port of a re-heater is permitted even when the damper is made unnecessary. SOLUTION: The simplification of constitution as well as the reduction of a boiler plant cost are contrived by making an economizer outlet port damper unnecessary while accurate damper control is permitted by controlling a superheater gas distributing damper 3 and a re-heater gas distributing damper 4 while considering a correcting coefficient compatible to a load. Especially, upon controlling the opening degree of the superheater gas distributing damper 3 and the re-heater gas distributing damper 4, a given minimum degree of opening is set as a fixed degree of opening and the fluctuation of distribution, exceeding the minimum degree of opening, is controlled by considering the correcting coefficient compatible to the load.

Title: Discharge lamp lighting device and lighting system
Inventor: USAMI TOMOKAZU
IPC: H05B41/24
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device capable of coping with an abnormal situation of a fluorescent lamp with a simple constitution. SOLUTION: This discharge lamp lighting device lights a fluorescent lamp FL1 by high frequency-lighting by actuating an inverter circuit 13 and applying a high frequency voltage to the lamp. If it is detected that the fluorescent lamp FL1 is not mounted, the inverter circuit 12 stops its operation. It is possible that, when it is not used for a long time, an oxide film is formed between the fluorescent lamp FL1 and a lamp socket 4, an electric current is not sent to a passage through a current transformer CT1 because a contact resistance increases, and the inverter circuit 12 stops its operation. A direct current is sent to a current passage formed from a full wave rectifier circuit 11 to filaments FL1a, FL1b through a resistance R1 and a resistance R2.  Since the contact resistance is destructed, even if the oxide film is formed and the contact resistance increases, the inverter circuit 13 is prevented from stopping its operation.

Title: Method for preventing communication of error signal and error signal preventing circuit
Inventor: UCHIDA KAZUHIRO
IPC: H04L25/40
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to execute accurate signal communication even when a clock is delayed by extending a signal output period to its specific multiple on the output side IC. SOLUTION: A D flip flop(D-FF) 5 inputs an internal output signal from the output side IC to a D terminal and inputs a clock signal to a clock terminal and the output terminal Q of the D-FF 5 is connected to the other input of an OR circuit 6. An internal output signal is inputted to one input of the circuit 6 and an output from the circuit 6 is outputted as an external output signal together with the clock signal. The external output signal becomes an external output signal to be outputted for a period 1.5 times as long as the period of a clock. Even when a clock to be supplied to an input side IC together is delayed, accurate communication can be executed because a signal is outputted for a period 1.5 times as long as a normal period. Provided that the method is effectively only when a signal is not continuously outputted synchronously with a clock in unidirectional signal communication.
