An ATM communication apparatus and the bandwidth control method thereof that are capable of bandwidth control to guarantee the minimum cell rate and limit the upper-limit for each of subscriber terminals, dynamically and fairly distribute the shared bandwidth based on the registered status and can be easily applied to the system that is already operating the actual service.
摘要:
A phosphorus-doped amorphous silicon film and a silicon nitride film are serially grown over a semiconductor substrate. The obtained stack is patterned so as to obtain word lines. A CVD oxide film is grown on the entire surface and then anisotropically etched to thereby form sidewalls on the lateral faces of the word lines. An ONO film previously formed just under the CVD oxide film is also removed by the etching. The semiconductor substrate is etched to thereby form a groove, where masking is effected by the silicon nitride film, silicon oxide film and sidewall. Boron ions are doped by ion implantation through the same mask into the bottom of the groove to thereby form a channel stop impurity-diffused layer. Then, an inter-layer insulating film is formed over the entire surface.

An electrolytic aqueous solution tank (4) and a waste liquid tank (32) are disposed above a pump (6) to prevent electrolytic water from flowing to the waste liquid tank from the electrolytic aqueous solution tank under a siphoning effect. The electrolytic aqueous solution tank (4) and the waste liquid tank (32) are formed separately from the housing (2) so that both tanks can be attached to and detached from the housing (2). The electrolytic aqueous solution tank (4) and the waste liquid tank (32) are urged against the housing (2) by means of an elastic member (66) attached to the tank (4) and an elastic member (70) attached to the tank (32). As a result, when the waste liquid tank (32) is removed, it is inclined and hence there is no fear of spilling of waste liquid.
摘要:
In a pivoted tensioner lever for maintaining tension in an automobile engine timing chain, an arc-shaped shoe on which the timing chain slides, comprises a guide region, which guides and controls the part of the transmission chain approaching the end of the lever near the pivot axis, and a pressing region, which is continuous with the guide region, and which absorbs the looseness of the transmission chain moving away from the tip of the lever. The radius of curvature of the pressing region is smaller than the radius of curvature of the pressing region.

A low cost hydraulic tensioner of die-casting metal or synthetic resin with a separate metallic cylinder free from dropping out of the cylinder and fine surface finishing, is provided. The tensioner 1 comprises a metallic cylinder 4 fitted to a cylindrical hole 3 formed in a body 2, a plunger 5 energized by a spring 7 and a pressure oil chamber 8 formed between the inner part of plunger 5 and the cylinder 4. The cylinder 4 is provided with a bottom plate 4B having a through hole 4A allowing the inflow of oil. The bottom plate 4B is prevented from dropping out from the body 2 by being engaged by the spring 7.
摘要:
In a chain tensioner having a plunger biased to protrude from a housing by a spring, a pair of wedge-shaped cams are received in tapered recesses in the end of the housing, cooperate with racks formed on opposite sides of the plunger, and are urged against oblique seats formed by the tapered recesses by a biasing spring. The cams and racks produce a ratcheting action maintaining chain tension by preventing retracting movement of the plunger. The cams and racks disperse the load imparted to the plunger by the chain, and reduce localized wear, allowing the housing to be made from a light weight material such as aluminum. Accuracy requirements associated with conventional pawl-type ratcheting tensioners are avoided.
摘要:
An image recording apparatus includes an image forming device, a fixing device, a cooling device and a controller. The image forming device forms an image on a recording medium on the basis of an image signal generated by an image signal generating unit. The fixing device uses heat to fix the image formed on the recording medium, and the cooling device cools the inside of the apparatus. The controller selectively executes either a first economy mode in which the cooling device is activated and the fixing device is inactivated on the basis of a command from the image signal generating unit, or a second economy mode in which both the cooling device and the fixing device are inactivated.
