IPC: H02M3/335
Filed: 1984-02-29
Abstract: PURPOSE:To accelerate a switching speed by supplying an electric component for aiding the switching of ON and OFF of a switching element to the switching control input of the element. CONSTITUTION:A pulse generated at a pulse generator (a) is applied through a pulse transformer T1 and a resistor R1 to the base of a transistor TR1, which is switched from OFF to ON. In this case, the current supplied to the base of the transistor TR1 becomes an excess current superposed with a pulse current supplied through a capacitor C1 and a resistor R2 from the tertiary winding N3 to the current limited by the resistor R2 from the secondary winding N2 of the pulse transformer T1. When the transistor TR1 is switched from ON to OFF, the current flowed from the base of the transistor TR1 is flowed through the diode D1 in addition to the resistor R1.

Title: Liquid fuel burning device
Inventor: OMUKAE YOSHIZO
IPC: F23Q25/00
Filed: 1986-02-21
Abstract: PURPOSE:To prevent the generation of an offensive odor at the time of flame extinction by installing a suck-in device which sucks in a mixed gas of liquid fuel and air and exhausts to the outside with no heating of the gas. CONSTITUTION:By the flame extinction operation, burning amount is reduced and an excess air ratio varies. As fuel component which causes the generation of an offensive odor is sucked into the flow paths which are used for supplying air normally (blast pipes 11, 12) by a blower 10 previously before the step of the generation of the offensive odor, the excess air ratio reaches a maximum rapidly and the flame extinction takes place at the same time and so, the generation of the offensive odor is improved to be almost none. As fuel which is sucked into the flow paths (11, 12) is in the condition of vaporization or corpuscular, the gas has very weak odor and considerable reduction of the offensive odor is obtained. When the gas is exhausted from the paths (11, 12), the gas is not hardly affected by heat from a flame hole part 18 and the place nearby burning space of which temp. becomes high due to burning and therefore, the gas is exhausted before the outbreak of the reaction which changes fuel component into the offensive one.

IPC: H05K1/11
Filed: 1990-02-21
Abstract: PURPOSE:To oscillate a plurality of timing signals by only one plug by forming the plug in a comb shape in a printed circuit board for placing electronic circuit components. CONSTITUTION:A printed circuit board 1 has a pectinated plug 4, a grounded contact 5 supplies a low level to the plug 4 in a state that the board 1 is inserted, and the plug 4 is formed to be shorter than a plug 2 for a power source. When the plug 2 is brought into contact with a contact 3, the plug 4 becomes a higher level than a pull-up resistor 6, the plug 4 is then brought into contact with the contact 5, becoming a low level, further isolated from the contact 5, becoming a high level. Thus, after the plugs 4, 5 are repeatedly connected/opened, they are finally brought into contact therewith, and a timing generator 7 connected to the plug 4 generates a plurality of timing signals with the signal as a clock signal. Thus, a plurality of timing signals can be formed from one plug.
