Title: Piston-cylinder device
Inventor: HAINTSU RANPERUTO
IPC: F15B15/08
Filed: 1982-11-09
Abstract: In a piston-cylinder device, a guide ring (11) that is provided with helical flutings (12, 26) is arranged between the piston (25) and the cylinder (2). This guide ring (11) has an inner fluting (12). With this it engages an outer fluting (26) on the piston (25). The outer ring surface (13) is smooth. It is provided with full length grooves (15) in order to conduct the pressure medium beneath the lifting piston. The piston (25) is fluted (26) only on one portion of its outer surface. The inclination of this helical fluting (12, 26) amounts to 10 DEG -60 DEG . A rotation-preventing plate (21) holds the piston (25) against rotation. This piston-cylinder device is formed especially for very high and also for eccentric loadings.

Abstract: PURPOSE:To reduce the deterioration in a radiation pattern by adopting a part of a sub reflection mirror as a frequency selective reflection mirror so as to make the beam width of each frequency band nearly equal to each other. CONSTITUTION:The frequency selecting reflection mirror FSR11 acts like reflecting a radio wave in frequency f1 and transmitting that in frequency f2, and a radio wave irradiated to the sub reflection mirror 2 from a primary radiator 3 with an apparent angle of thetam0 of a main reflection mirror 1. The radio wave irradiated with an apparent angle of thetam1 is irradiated in the main reflection mirror Dm1 in an angular range smaller than the angle thetam1 and transmitted through without being reflected on the FSR11 in an angular range larger than the thetam1. Further, the radio wave reflected from the mirror 1 is blocked by the mirror 2 and since the FSR11 shows transmittivity to the f2, the equivalent blocking area is Ds1. Then the relation of Ds0/Dm0approx.=Ds1/Dm1 with respect to the f1, f2 is established. Thus, the relation of lambda1/Dm0approx.=lambda2/Dm1 is obtained, the lambda/D is made nearly equal in the common frequency and the deterioration in the radiation pattern is reduced.

IPC: G01B7/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To effectively, simply detect the position of a magnetic information recording region by collating a magnetic output read by a magnetic sensor with a preset magnetic output change. SOLUTION: When an allowable displacement amount of a magnetic information recording region 3 is expressed as ±α and a magnetic output corresponding to the amount is expressed as x%, the state that the output falls within the range of x% to 100% of a maximum magnetic output can be detected that the region 3 is disposed in an allowable position (its displacement amount is ±αor less) of a magnetic recording medium 1. The position of the region 3 is detected by utilizing that an amplitude of the output read by a magnetic sensor H is changed according to a relative position between the region 3 and the sensor H.  Thus, even in the case that the region 3 is covered with a concealing layer or the like so that the region 3 is impossible to be optically sensed or optical characteristics of the region 3 are very near at those of a circumference, the position of the region 3 can be effectively detected.
