A piston ring which can sustain a superior effect of preventing aluminum cohesion for a long time in a high output engine is provided. At least one of the upper and lower side faces of a piston ring is coated with a polyimide film having hard particles dispersed therein. Employed as the hard particles may be alumina, zirconia, silicon carbide, silicon nitride, cubic boron nitride, or diamond. The hard particles are to be 0.01 to 5 μm in average particle diameter, and the film is 2 to 30 μm in thickness.

Provided is a process for producing an aromatic hydrocarbon efficiently at high yield from a lower hydrocarbon containing methane as a major component, and such a process for producing an aromatic hydrocarbon includes the step of reacting a lower hydrocarbon containing methane as a major component in the presence of a transition-metal-containing crystalline metallosilicate catalyst which is obtainable by supporting 5 to 25 parts by weight of a transition metal (X) on 100 parts by weight of a modified crystalline metallosilicate obtainable by subjecting a crystalline metallosilicate to a series of treatment (A) including a step (i) of eliminating part of a metal from the crystalline metallosilicate and a silylation step (ii).

There is provided a baseball including an inner core, and an outer core covering an outer circumferential surface of the inner core, the inner core being formed to have a dimension of 20% or more and 80% or less of an outer diameter of the inner core and the outer core of the baseball, and having a dynamic viscoelasticity loss coefficient (tanδ) of 0.3 or less, the outer core being formed to have a thickness of 10% or more and 40% or less of the outer diameter of the inner core and the outer core of the baseball, and having an elastic modulus of 1.5 MPa or less. As a result, there can be obtained a baseball that achieves a high level of safety when the baseball hits against a human body and achieves a hit distance equal to and longer than that of a ball for hardball.

Disclosed is technology capable of improving operability of a multi-function image processing apparatus with simple inexpensive structure and easily designing necessary system software. After start-up, the apparatus is connected to an IPv6 router on a network, prefix information is acquired from the router, there is generated an IP address unique to each of image processing functions such as printing, scanning and FAXing on basis of the acquired prefix information, the apparatus communicates with other appliance on the network by use of the IP address generated for every image processing function, and each image processing function operates corresponding to a result of the communication. Transfer task transfers data to be inputted and outputted among print task, scan task and facsimile task by use of IP addresses each different for every function, and the respective tasks run on a time-division basis using a task switchover by OS.

A seat back locking device for an automobile for a seat back 5 configured so as to be capable of being changed from an upright position to a folded-down position and vice versa, including a locking mechanism 10 for locking the seat back 5 in the upright position, a locking knob 20 for unlocking the locking mechanism 10, and a key cylinder 30 capable of locking and unlocking the locking knob 20. In the locking device, a contact part 33 that comes into contact with a contacted part 26 provided on the locking knob 20 is connectingly provided integrally with a cylinder body 31 of the key cylinder 30 so that the key cylinder 30 can be changed over between a locked state in which the contact part 33 comes into contact with the contacted part 26 to inhibit the rotation of the locking knob 20 and an unlocked state in which the contact part 33 does not come into contact with the contacted part 26 to allow the rotation of the locking knob 20.
摘要:
A fuel cell assembly has a housing defining an electricity generation/combustion chamber, and electricity generation/combustion means disposed within the housing. A fuel gas and an oxygen-containing gas are supplied to the electricity generation/combustion means, and a combustion gas formed within the electricity generation/combustion chamber is discharged from the electricity generation/combustion chamber. A heat exchanger having a first channel and a second channel is disposed on at least one surface of the housing, the combustion gas is discharged from the interior of the electricity generation/combustion chamber through the first channel of the heat exchanger, and one of the oxygen-containing gas and the fuel gas is supplied to the electricity generation/combustion means through the second channel of the heat exchanger. A plurality of electricity generation units are arranged in parallel within the housing, and each of the electricity generation units includes a cell stack constituting the electricity generation/combustion means.

A motorcycle is provided in which the size of the body frame is restricted from increasing in a vehicle-width direction while enhancing the frame rigidity. The body frame includes a head pipe and left and right front frame sections which extending from the head pipe. The left and right front frame sections have left and right side wall sections which extend in a longitudinal and vertical directions of the vehicle. Left and right side wall sections are disposed on the left and right sides of the engine unit. The engine unit is supported by the left and right side wall sections which have relatively high rigidity, thereby enhancing the supporting rigidity of the engine unit. This type of engine unit support ensures body frame rigidity without widening the space between the left and right body frame sections in a vehicle-width direction.
