Abstract: PURPOSE:To prevent detonation such as, for example, knocking from occuring, by controlling the injection amount of knocking restraining liquid in accordance with the operating condition of an engine, and as well by modifying the increment of the knocking restraining liquid upon occurrence of detonation. CONSTITUTION:During engine operation a control device 50 determines the amount Wt of water injection and the value DELTAWt of water injection increment compensation in accordance with the rotational speed of an engine detected by a rotating angle sensor 48b and the amount of intake-air detected by an air flowmeter 19. Then, if it is determined in accordance with the output of a quantity sensor 49 that the amount of water in a tank 4 is not zero, discrimination is made on whether knocking occures or not in accordance with the output of a knocking sensor 57. If the knocking occures, then discrimination is made whether a water injection amount modifying flag is ''1'' or not. If it is not ''1'' the amount of water injection is set to Wt+nDELTAWt where n is the frequency number of water injection compensation, and water injection from a water injection valve 41 is carried out. If it is ''1'', the amount of water injection is set to the value where n is added with 1 and water injection is carried out.

Title: Self-excited piezoelectric transformer inverter
Inventor: FUKUI MASAHIKO
IPC: H02M7/537
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To light up a discharge lamp, etc., efficiently at an intrinsic frequency by applying voltage induced in a tertiary winding of an electromagnetic trans former which has a primary, a secondary, and the tertiary winding to the base of a switching transistor and letting the circuit oscillate at a frequency lower than a resonance frequency intrinsic to a piezoelectric transformer. SOLUTION: With application of power from a DC power supply Vi, voltage is applied to the base of a switching transistor Q1 through a resistor R1 and then collector current starts flowing through a primary winding N1 of an electromagnetic transformer T. Then, voltage is induced across a tertiary winding N3 of the electromagnetic transformer T and thereby the collector current of the switching transistor Q1 increases. As for a secondary winding N2 of the electromagnetic transformer T, voltage stepped up by the winding ratio is applied to a primary side of a transformer PT for measurement equipment and then high voltage is induced across an output terminal at the primary side of the transformer PT for measurement equipment. When the induced voltage becomes a start-up voltage for a cold cathode tube CCFL or above, the cold cathode tube CCFL lights up.

IPC: F04C18/348
Filed: 1983-03-23
Abstract: PURPOSE:To prevent a rotary sleeve from being brought in contact with the internal peripheral surface of a center housing so as to enable the rotary sleeve to be smoothly rotated, by both allowing air to flow into an air bearing chamber and providing an air reservoir groove in the end part of a contact area with the rotary sleeve on the internal peripheral surface of the center housing. CONSTITUTION:If a rotary compressor is operated, a working chamber 43 in the delivery side becomes a high pressure, pressing a rotary sleeve 30 to the delivery side. And this pressing force is changed in accordance with the position of a vane 16, causing the center of the rotary sleeve 30 to draw an oval pattern, and its peripheral surface tends to come in contact with the internal peripheral surface of a center housing 22 in a contact area in the delivery side. An air reservoir groove 722 is provided in a final end 82 of the contact area, in this way, an air flow increased by external air sucked from a flow inlet 71 the more increases air bearing load power in the contact area of an air bearing chamber 40. Accordingly, the rotary sleeve 30, being not brought in contact with the internal peripheral surface of the center housing 22, is smoothly rotated.
