Abstract:
A pneumatic tire with good fuel efficiency, drainage performance and uneven wear resistance is provided. A pneumatic tire has a tread surface provided with circumferential main grooves to define a center region and two side regions. The center region is provided with a first circumferential narrow groove and second circumferential narrow grooves located between the first circumferential narrow groove and the circumferential main grooves; and center rib-like land portions including first center rib-like land portions defined by the first circumferential narrow groove and the second circumferential narrow grooves, and second center rib-like land portions defined by the second circumferential narrow grooves and the circumferential main grooves. The center rib-like land portions located next to each other with the center circumferential narrow grooves being therebetween are adapted to supportingly contact with each other. The second circumferential narrow groove has a width larger than that of the first circumferential narrow groove.
Abstract:
A virtual machine control method and a virtual machine system are disclosed. In the case where a guest program can be operated in a plurality of address translation modes and the same guest virtual address is translated into different host real addresses in each address translation mode, the illegal access to a host real address by illegal address translation by double registration in the same page table is avoided, and the address translation mechanism is efficiently operated. A plurality of host page tables are prepared in the main storage, and one of the host page tables is selected with the change in address translation mode of the guest program. The bottom address of the selected host page table is set in the host page table register thereby to switch the host page table.
Abstract:
A compression element located inside an enclosed compressor is disclosed for receiving a connection pipe from outside the compressor. The compressor has an opening one in one of its walls. The compression element has a bore running through it. An inlet end of the compression element is joined to the wall of the compressor at the opening. The inlet end of said bore is tapered in the form of a curved shape that spreads smoothly toward the opening. A guide pipe has one of its ends installed into the opening from outside the compressor. A connection pipe having a cooper plated exterior surface is inserted through the guide pipe, press-fitted into the inlet end of the compression element and joined to the compression element. The connection pipe has another end connected to a suction pipe for circulating a refrigerant within the compressor via the compression element.

Abstract:
A solid-state image sensor comprises a photodiode which is provided in a p-type substrate or a p-type well and composed of a first n-type region for storing photoelectrically converted signal charges, a gate electrode provided above the substrate or well so as to be adjacent to one end of the photodiode, and a n-type drain provided at the surface of the substrate or well opposite to the photodiode, with the gate electrode interviewing therebetween. There is provided a second n-type region which is formed so as to be in contact with the upper part of the first n-type region on the gate electrode side and one end of which is formed to self-align with one end of the gate electrode to be part of the photodiode. This construction prevents the short-channel effect of the signal read transistor section and reduces or eradicates the left-over signal charges stored in the photodiode, thereby reducing noise and improving the sensitivity of the sensor.
