Abstract: A control system for a pre-mixture compression-ignition engine is provided, configured such that in a first combustion mode, the control unit controls the fuel injection valve to have a fuel amount within a mixture gas in an outer circumferential portion of the combustion chamber larger than in the center portion, the swirl generating part to generate a swirl flow in the outer circumferential portion, and the spark plug to ignite the mixture gas in the center portion. In a second combustion mode, the control unit controls the fuel injection valve to start a fuel injection on intake stroke so that the mixture gas is formed in the entire combustion chamber, the swirl generating part so that a swirl flow becomes weaker than in the first combustion mode, and the spark plug to ignite the mixture gas before CTDC.

Abstract: In response to a switching demand from an all-cylinder operation to a reduced-cylinder operation, the amount of air to be taken into each of cylinders 2A to 2D is made larger than the amount of air during the all-cylinder operation in a normal state. Preparatory control of changing the ignition timing of ignition device to a timing on the retard side with respect to the ignition timing during the all-cylinder operation in the normal state is executed. After termination of the preparatory control, the reduced-cylinder operation is started. During execution of the preparatory control, the valve closing timing of an exhaust valve 9 is changed to a timing on the advance side with respect to the valve closing timing thereof during the all-cylinder operation in the normal state so as to reduce the amount of internal EGR gas in at least a part of an operating range C.

The fuel control system includes a fuel injector for directly injecting the fuel into the combustion chamber, a tumble flow generator for generating the tumble flow within the combustion chamber, and a fuel injector controlling module for causing the fuel injector to inject the fuel at a first injection timing and then inject a smaller amount of fuel than an amount injected at the first injection timing, in a direction opposing a positive direction of the tumble flow at a second injection timing, the first injection timing designed to be in an intake stroke of the cylinder, the second injection timing designed to be in a latter half of the compression stroke of the cylinder.

Abstract: Provided is a method for producing a circular wafer using a grinding tape to grind the edge of a wafer comprising a crystalline material. A primary grinding step is provided for contacting a grinding body to the peripheral portion of a wafer placed centered on a horizontal stage and rotating the stage, thus grinding the peripheral portion. The radius of the wafer is measured, and a radius is set that is no greater than the measured smallest radius, and the difference ?r between the set radius and the measured wafer radius along the peripheral portion is determined. The portions of the peripheral portion at which ?r is greater than a predetermined value are determined and a secondary grinding step is provided for contacting the peripheral portion and the grinding body, rotating the stage forwards and backwards in a predetermined range of rotational angles, and grinding the peripheral portion.

Abstract: In response to a switching demand from an all-cylinder operation to a reduced-cylinder operation, the amount of air to be taken into each of cylinders 2A to 2D is made larger than the amount of air during the ail-cylinder operation in a normal state. Preparatory control of changing the ignition timing of ignition device to a timing on the retard side with respect to the ignition timing during the all-cylinder operation in the normal state is executed.

Abstract: A printing system includes a post-processing apparatus and an information processing apparatus. The post-processing apparatus applies post processing to a sheet material output from a printing apparatus related to execution of a print job. The information processing apparatus manages a print workflow that associates an operation executed by the post-processing apparatus with a first operation performed by a worker managing the first operation or a serviceman maintaining the printing apparatus. The apparatus generates a print workflow, acquires operation information related to a component to be replaced in the print job, and determines whether the component needs to be replaced during the execution of the print job.

Abstract: A print system having a printing apparatus and a post-processing apparatus, and a print control method thereof are capable of executing an inline job requiring printing by the printing apparatus and post-processing by the post-processing apparatus and an offline job that does not include print processing by the printing apparatus but requires post-processing by the post-processing apparatus, and allow a recovery process for carrying out unfinished processing in the inline job when the inline job is interrupted during execution thereof. On the other hand, if the offline job is interrupted, that offline job is canceled and, if there is a job that is unaffected by a cause of the interruption, execution of that job is allowed.

Abstract: A winding device is provided behind a rearmost-row seat and extends in a vehicle width direction to wind up a tonneau cover member. The tonneau cover member comprises a cover body portion and a board portion connected to a rear end of the cover body portion and has its rear end portion capable of engaging with an engaged portion of a lift gate. The lift gate further includes a pair of restraint portions at a specified position of both end portions of the inner face thereof which is located above the engaged portion, which is operative to restrain the cover body portion from moving upward when the lift gate is fully open and the tonneau cover member engages with the lift gate through a contact thereof with the board portion to stop further upward moving of the board portion.
