摘要:
An exhaust gas recirculation device for an engine having a cylinder head with a suction port and an exhaust port, provided with a mechanism for recirculating a portion of exhaust gas to the suction side of the cylinder head, comprises a connection hole is opened through a wall of the cylinder head disposed between the suction port and the exhaust port. The connection hole is bored vertically slantwise. The connection hole at the suction side is opened along the direction of swirls of sucked air. A throttle is disposed in at least either a suction flow passage communicating with the suction port or an exhaust flow passage communicating with the exhaust port so that the opening area of the suction flow passage or the exhaust flow passage can be adjusted by the throttle.

A washing basket doubling as a spin-drier is disposed rotatably in a water-tub. A motor drives the basket, which generates centrifugal force. The centrifugal force cause cleansing water to run through the fibers of clothes in the basket, thereby cleansing the clothes. A control device cause variation of the spinning of the basket so that the centrifugal force working on the clothes is varied, which cleanses the clothes more effectively. The clothes in the basket receive only water-moving-force, and they can be cleansed without being damage or entangled.

A facilitation mechanism between users and databases is composed of a user agent for interfacing between users and the entire facilitation mechanism, a DB agent for interfacing between each database and the facilitation mechanism, and a facilitation agent for mediating between each of the agents, which are distributed. By adopting this system in the present invention, a facilitation mechanism in which scalability can be secured for an increase in the number of users, the addition of databases, etc., operation load and operation managing cost can be distributed, and security of information can be protected, can be realized.

An antenna system for a vehicle is provided. The antenna comprises an antenna disposed on a window glass and having a feed point, a matching circuit connected to the feed point, and a coaxial cable connecting between the matching circuit and the radio receiver. The matching circuit includes a parallel circuit having a damping resistor, a first coil and a first capacitor. The matching circuit further includes a second coil and a second capacitor connected in series between an output side of the parallel circuit and a ground such that, assuming that MF1 is a lower limited frequency of medium-frequency (MF) broadcast waves and MF2 is an upper limited frequency of the MF broadcast waves, a receiving sensitivity of the antenna system has local maximum points which are present at a frequency F1 in the range from (MF1-170) to MF1 KHz and at a frequency f2 in the range from (MF2-230) to MF2 KHz, respectively, and a local minimum point which is present at a frequency f0 smaller than f1 and equal to or larger than 50 KHz.

A ferritic stainless steel having excellent oxidation resistance, toughness and hot workability contains 0.001-0.20% of at least one of Ca, Mg and Ba as an amount of [Ca]+[Mg]+1/5[Ba], and La: 0.06-0.5% and Ce: 0.002-0.050% in addition to C, Si, Mn, Ni, Cr, Al, Ti and N as a main component provided that these components satisfy relations of the following equations (1)-(3):[S].ltoreq.[Ca]+[Mg]+1/5[Ba] (1)[La]/[Ce].gtoreq.5 (2)Ti.gtoreq.48/12 [C]+48/14 [N] (3)
摘要:
A fine displacement device for establishing a measured micro displacement includes first and second plate members disposed in spaced relation to each other to define a gap therebetween with the plate members being secured to each other at opposed portions thereof. An internally threaded hole is formed through one plate member perpendicular thereto and an externally threaded screw is fastened in the hole with an end of the screw abutting against the other plate member. Upon turning the screw in one direction, the plate members will be deformed elastically in a direction perpendicular to the plate members and a distance between a plane of the first plate member and a deformed portion of the first plate member is used as a measure for establishing the micro displacement.
