  • Publication number: 20240151190
    Abstract: A control device for controlling an engine includes main-chamber injecting means (1,3) that supplies a main chamber (8) with fuel; sub-chamber injecting means (2) that supplies a sub chamber (5) with fuel after the main chamber injecting means (1,3) supplies the fuel; estimating means (21) that estimates a degree of knocking serving as indices of an intensity of the knocking and an occurrence frequency of the knocking; and fuel controlling means (22) that carries out, when the degree (N) of the knocking is a first predetermined value (N1) or more, fuel control that reduces a sub-chamber fuel amount representing an amount of fuel supplied by the sub-chamber injecting means (2). By reducing the sub-chamber fuel amount in this manner, the occurrence of knocking can be suppressed, so that the combustion state of a divided-combustion-chamber engine can be enhanced.

  • Patent number: 7158210
    Abstract: A projection exposure apparatus with a small size and low cost suitable for repeated pattern exposure. The apparatus includes an illumination system which irradiates light to a mask including plural columns of a mask pattern for repeated exposure to a member to form plural columns of an exposure pattern, a projection system which projects light from the mask onto the member, an exposure stage which moves the member, and a mask stage which moves the mask. The light irradiation and step driving of the exposure stage for moving the member by a movement amount equal to n times a pitch of the columns of the exposure pattern are alternately performed. The mask is moved by a movement amount equal to n times a pitch of the columns of the mask pattern with step driving of the exposure stage in early and later phases of the repeated exposure.

  • Patent number: 6280306
    Abstract: The invention provides a wafer polishing apparatus and a wafer manufacturing method which can improve uniformity in polishing wafer surfaces. A wafer holding head comprises a head body; a diaphragm stretched inside the head body; a carrier fixed to the diaphragm to be displaceable in the direction of a head axis while holding the wafer; a retainer ring disposed around the carrier in concentric relation and fixed to the diaphragm to be displaceable in the direction of the head axis; and a thin plate disposed so as to project from the head body along a surface of the diaphragm. With the provision of the thin plate, an excessive pressing force acting upon the retainer ring from the diaphragm is suppressed, and the wafer surface can be prevented from being excessively polished at an outer peripheral edge.

  • Patent number: 5777867
    Abstract: Herein disclosed are a method and an apparatus for supplying an electrical energy to a pair of discharge electrodes spaced apart from each other to cause an electric discharge in a gap between the discharge electrodes. There are firstly provided an alternating voltage generator for generating, as the electrical energy, an alternating voltage having a frequency, and a capacitor connected to the discharge electrodes in series. The alternating voltage generator has a series resonant frequency. The alternating voltage of the alternating voltage generator is applied to the discharge electrodes through the capacitor. The frequency of the alternating voltage is set approximately to the series resonant frequency of the alternating voltage generator to cause a dielectric breakdown in and allow an electric discharge current to flow through the gap between the discharge electrodes.
