Title: Resonance type converter
Inventor: HANAWAKA MASUO
IPC: H02M3/28
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce switching loss and also, stabilize the oscillation frequency even if input voltage or load ripples, by equipping a resonance type converter with a pulse width controller which determines the period for the main switching element to turn off so that it may stabilize the main output voltage into specified voltage, comparing it with reference voltage. SOLUTION: A trigger mask part 30 nullifies the trigger signals outputted by a zero voltage detector 10 while the mask signal generated in a timer part 20 is valid, and also, turns off the main switching element Q1 by the trigger signal after passage of the period when the trigger signal is valid. And, a pulse width controller 40 determines the period when the main switching element Q1 is turned off so as to stabilize the main output voltage into specified voltage, comparing the main output voltage with reference voltage Vref2. This prevents resonance frequency from going high.

Title: Silencer
Inventor: TORIGOE IPPEI
IPC: G10K11/16
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To reduce influence of air flow to a sound characteristic of an opening so as to improve silencing effect of a silencer by forming an opening of a silencer, to which a sound system is connected via the opening, into a shape, in which a length along the air flow direction is larger than the length in the direction orthogonal to the air flow direction. SOLUTION: A container with a volume V is connected to an exhaust pipe 1 connected to an internal combustion engine via a tube 3 with a cross section S and a length (1). This container 2 works as a spring element because of a compressing characteristic of contained gas, while gas inside the tube 3 works as a mass element. Therefore, a spring-mass system is constructed of the container 2 and the tube 3, and a Helmhotz resonator is constructed. On the other hand, in an opening 4 bored in the exhaust pipe 1 in the connection part for the tube 3, a length measured in the air flow direction is set to be longer while a length measured in the direction orthogonal to the air flow is set to be shorter, and as a result, influence of the air flow to a silencing characteristic of a silencer connected via the opening 4 can be suppressed.

The laser output drive (frequency fixing) signal fixes the frequency of the high-frequency voltage at a frequency out of the resonance frequency of the step-up transformer, and determines an ON period of the inverter drive signal, i.e., the pulse width based on the level of the laser command output signal. By preparing a control device 9a which fixes the frequency of the high-frequency voltage occurred in the inverter to a frequency out of the resonance frequency unique to the step-up transformer and changes the pulse width of the inverter, the laser output can be changed in a stable manner.
