An optical-pickup slider is characterized in that a light-transmitting-property substrate is bonded to a surface of a layer having a tapered through hole, on which surface a larger opening of the tapered through hole exists. Thereby, it is possible to prevent the layer having an aperture from being destroyed. A method of manufacturing the optical-pickup slider comprises the steps of a) making a tapered through hole in a layer layered on a first substrate and having a thickness smaller than that of the first substrate; and, after bonding a light-transmitting-property substrate to a surface of the layer, removing the first substrate so as to expose an aperture at a tip of the tapered through hole.

The invention relates to the field of gas-liquid pipeline connectors, in particular to a male connector and a rapid connector assembly adopting the same. The male connector comprises a male connector shell with the front end being an inserting end. The male connector shell has an axial direction extending in the front-back direction. A fluid channel extending in the front-back direction is arranged in the male connector shell and is provided with an opening in the inserting end of the male connector shell. A movable valve element is elastically assembled in the fluid channel in the axial direction and is in sealing fit with the opening, in the inserting end of the male connector shell, of the fluid channel. An elastic part providing forward acting force for the movable valve element is arranged in the male connector shell, and the movable valve element is elastically assembled in the fluid channel in the axial direction through the elastic part. The male connector is characterized in that guiding structures are arranged in the male connector shell and comprise the internal guiding structure guiding the movable valve element in the front-back direction and the external guiding structure guiding the elastic part in the front-back direction. The problem that a movable valve element cannot smoothly rebound due to the fact that the movable valve element of an existing male connector is prone to deflection is solved.

The invention provides a method of adjusting a machine tool. The method adjusts the machine tool so that, in ultra-precision machining of round bar-like work (W), the machine tool can rotate the work (W) while suppressing run-out of the axis of the work (W). In an axis position adjustment step (S5), a side surface of a projection portion of the work (W) held by a work holding mechanism (50) is measured while a work spindle (40) is rotated. A C-shaft adjustment screw (42b) is adjusted so that run-out of the work (W) is minimum and then the position of the work axis (C2) is fixed. In a support adjustment step (S6), with the position of the work axis (C2) fixed, a support block (91) is adjusted so as to support the work (W). In a support locking step (S7), the definition of the position of the work axis (C2) defined by the support block (91) is maintained by pressing the work (W) by a work presser (92). In a floating-restriction releasing step (S8), floating restriction by the C-axis adjustment screw (42b) is released.
