Title: Fluorescent lamp circuit and power supply device installed in fluorescent lamp circuit
Inventor: ASAYAMA ATSUSHI
IPC: H05B41/392
Filed: 1994-04-22
Abstract: PURPOSE:To construct a circuit and device in small sizes, preclude temperature rise of a switching element on the primary side of a converter transformer at the time of dimming, and avoid generation of noises. CONSTITUTION:A secondary winding n2 with an intermediate tap and a main winding n4 for a fluorescent lamp are furnished on the secondary side of a multi-output converter transformer T1, and the primary side is subjected to switching control using a switching element SW1 so that the output voltage of the main winding n4 becomes constant. Choke coils L2, L3 for limiting the lamp current are connected between one end of the secondary winding n2 and its intermediate tap and one end of the fluorescent lamp FL1. The dimming operation is performed by changing the on/off timings of bidirectional switch means DB3, SW3. According to this constitution, the impedance of the lamp current limiting choke coil viewed from the primary side can be made greater than conventional, and the current passing through the primary side switching element SW1 can be lessened, and it is feasible to construct the device in a small size.

Title: Acceleration control mechanism for fuel injecting device
Inventor: SEKIYA MITSURU
IPC: F02D3/00
Filed: 1989-04-04
Abstract: PURPOSE:To perform smooth acceleration running through prevention of leak spark of an air-fuel ratio by a method wherein during acceleration in a low temperature state, opening operation of an air valve is delayed instantaneously. CONSTITUTION:When, in a state in which the temperature of cooling water for an engine is low, an engine is started, an air valve 3 is in an initial opening position in a slow zone, and intake air flows through openings 3a and 3a. A negative pressure P2 generated on the downstream side of a valve 3 according to an air flow rate is applied on a negative pressure chamber 8 of a vacuum actuator 6 through a negative pressure passage 10. In this case, since a bypass negative pressure passage 22 is closed by means of a valve 24, the negative pressure is applied after the passage of it only through a first throttle 21. By effecting rapid acceleration, a throttle valve 4 is opened, a flow rate of air passing through the openings 3a and 31 of the valve 3 is increased and the negative pressure P2 exceeds a given value. Thereby, the valve 3 is started to open but the opening motion of the valve 3 is temporarily delayed because of the throttle 21, the negative pressure P2 is increased only for a short time, a fuel flow rate is increased, and an air-fuel ratio of fuel-air mixture during acceleration is brought into a rich state.
