Alpine ski (1) which can be broken down over its length into a tip area (2), a binding area (3) and a heel area (4), in which the side line is such that the binding area (3) has a minimum width level (LP), the tip area (2) has a front maximum width level (LS), and the heel area (4) has a rear maximum width level (LT), characterized in that:the radius of the side line, calculated on the basis of three points (5, 6, 7) on the side line, respectively a first point (5) located at the front maximum width level (LS), a second point (7) located at the rear maximum width level (LT), and a third point (6) located centrally between the levels (LS, LT), is between 7 and 21 meters;the pressure distribution along the side line is such that, when the ski is placed on a flat surface (20) so that its underside (22) forms an angle (alpha) of 45° with the flat surface (20), and when the ski receives, at the location of the center of the boot, a force (F5) of 400 Newtons perpendicularly to its underside (22), the pressures measured along the side line differ by less than 10% from the average value of the three pressures measured respectively at the rear maximum width level (LT), at the minimum width level (LP) and at the front maximum width level (LS).

The invention solves the problem of designing and manufacturing springs made of elastic materials, particularly steel springs, with prescribed characteristic (dependence of flex on external load) given by a smooth (i.e. differentiable) non-linear function. The method according to the invention consists in forming an elastic body with suitably shaped regions of diversified stiffness and (possibly) diversified initial internal stresses (this suitable shape of the regions lies at the hart of the invention and is covered by separate patent claims).

A controller comprises power transmitting means (11) for amplifying the force applied on the operating shaft (6) and transmitting to the valve rod (4); and a slow start means (12) for slowly moving the operating shaft (6) upward are arranged. The slow start means (12) includes a piston (8) that moves up and down with respect to the operating shaft (6); a pressure spring (44), arranged between a pressure spring receiver (43) arranged at the operating shaft (6) and the piston (8); a constantly opened communication passage (47) and an auxiliary communication passage (49) for communicating the pressure chamber (10) and the operation gas introducing chamber (27); a flow adjusting valve (48) provided in the constantly opened communication passage (47); and an open-close valve (50), arranged in the auxiliary communication passage (49), for opening the communication passage (49) when the piston (8) is at the lower most position and closing the communication passage (49) when raised from the lower most position by a predetermined distance and reaching the auxiliary communication shut off position.

The method provides the identification, in a succession of acquired images each formed from a matrix of pixels, of a following sub-image extracted from a following acquired image corresponding to a prior sub-image extracted from a prior acquired image. The method comprises the steps of: —calculating, for the prior sub-image, at least one distribution of a characteristic quantity of each pixel for blocks forming a predefined partitioning of the sub-image; —calculating the same distribution for at least two would-be sub-images of the second format extracted from the following acquired image; and—determining the corresponding following sub-image from among the would-be sub-images, as the sub-image where the or each calculated distribution has the highest correlation with the same calculated distribution for the prior sub-image.

A nozzle head NH of a plasma processing apparatus comprises an annular inner holder 3, an annular inner electrode 11 surrounding this holder 3, an annular outer electrode 21 surrounding this electrode 11, and an annular outer holder 4 surrounding this electrode 21. The inner holder 3 is provided with a plurality of bolts 7 spacedly arranged in the peripheral direction and adapted to push the inner electrode 11 radially outwardly. The outer holder 4 is provided with a plurality of bolts 8 spacedly arranged in the peripheral direction and adapted to push the outer electrode 21 radially inwardly. Owing to this arrangement, the operation for disassembling, assembling and centering the annular electrodes 11, 21 can be carried out with ease.

A second objective thereof is to provide a method of manufacturing optical devices that prevents the occurrence of fine dust and maintains the optical characteristics satisfactorily. A third objective thereof is to provide a method of manufacturing optical devices of a multi-layer configuration that are obtained by applying a scribing / cutting method. A method of manufacturing optical devices in accordance with the present invention, wherein an optical wafer having surfaces polished to a mirror finish is divided into a plurality of optical chips, is provided with a first step of providing hairline cracks by a diamond blade edge in one main surface of the optical wafer and a third step of applying pressure along the hairline cracks after the first step, to divide the optical wafer into the plurality of optical chips.

To provide a printing device such as an inkjet device capable of transporting a recording medium at satisfactory precision with a simple configuration. The inkjet device includes a feed amount correcting section that corrects a feed amount of a recording medium, and a control section that controls the feed amount correcting section. The feed amount correcting unit includes a moving section that moves with a movement of the recording medium in a transporting direction and a displacement sensor section that detects a displacement amount of the moving section, and the control section controls the feed amount of the recording medium based on a difference between a feed amount acquired at a time of printing and a set feed amount set in advance.
