Abstract: The present invention relates to a fluidic cylinder. This fluidic cylinder is configured in such a manner that a piston unit is received in an axially displaceable manner within a cylinder tube formed in a rectangular cross-sectional shape. The piston unit has: a base body having the front end of a piston rod staked thereto; a wear ring having the base body received therein and having a magnet incorporated therein; and piston packing adjacent to the wear ring. The piston unit is integrally held at one end of the piston rod. The wear ring and the piston packing are formed in a rectangular cross-sectional shape corresponding to the rectangular cross-sectional shape of the cylinder tube and are provided rotatable relative to the piston rod.

Abstract: Panel units (24a to 24d) continuing an operation indicating panel (20) each have a rectangular surface S with length and width each being substantially an integral multiple of a predetermined reference size (L). The panel units (24a and 24d) are placed so that their surfaces S may be adjacent to one another. A whole surface (AS) consisting of the surfaces S of all the panel units (24a to 24d) is formed in a rectangular shape with length and width each being substantially an integral multiple of the predetermined reference size (L). The arrangement and the like of the panel units (24a to 24d) can be easily changed.

Abstract: In a display and input device (CP) displaying information on a display (DP) and performing changing of the information and communication through switch operating means (CSW1), the switch operating means (CSW1) are arranged on the left and right edges of the display (DP), opaque members among members forming the switch operating means (CSW1) are arranged outside the screen of the display (DP), and only transparent members are arranged on the display (DP). Thus, a switch operation can be performed while recognizing functions of the switch operating means (CSW1) and the switch operating means (CSW1) having the stroke feeling and click feeling of a mechanical switch so that an operating environment having excellent operability and implementing reliable input can be obtained.

Abstract: A phosphating solution that contains from 3 to 30 g/l of zinc ions, from 0.1 to 20 g/l of ferrous ions, from 5 to 60 g/l of phosphate ions, from 5 to 60 g/l of nitrate ions, and a source of hydroxylamine in a concentration corresponding stoichiometrically to from 0.5 to 4 g/l of hydroxylamine and in which there is a weight ratio of zinc to phosphate that is from 0.1:1 to 1:1 deposits on steel to be cold worked a phosphate conversion coating suitable as a lubricant carrier. This phosphating solution, which may optionally contain one or more of calcium, nickel, cobalt, and copper cations and simple and complex fluorine-containing anions, makes it possible to lower the temperature of the treatment solution, reduce the amount of sludge, improve the quality of the coating film, and allow single-liquid type replenishment to be used. Preferably the surface to be phosphated is immersed in the phosphating solution, maintained at a temperature of 35 to 80° C., for 2 to 20 minutes.

Abstract: An aqueous zinc phosphate conversion coating that contains 5 to 50 g/L of phosphate ions, 0.2 to 10 g/L of zinc ions, and 0.5 to 4.0 g/L as hydroxylamine of a hydroxylamine source, and also: (1) contains 0.01 to 5.0 g/L polycarboxylic acid or salt thereof and/or starch phosphate; or (2) has a zinc ions/phosphate ions weight ratio below 0.27 and a zinc ions concentration of at least 2.0 g/L forms high quality zinc phosphating coatings on metal surfaces even if the surfaces have not been previously conditioned by contact with a dispersion of colloidal titanium.

Abstract: A display unit with touch panel includes a press detection switch for detecting a press on a touch panel at a pressure exceeding a predetermined level so as to output a press detection signal, a driving-signal generating circuit responding to the press detection signal to generate a driving signal, a driving portion actuated by the driving signal to drive the touch panel into displacement thereby providing an operator with a tactile feedback, and an AND circuit for outputting an AND signal upon receipt of both of a coincidence detection signal from a coincidence detecting circuit and the press detection signal from the press detecting switch, and a gate circuit for inhibiting a passage of the operated-position signal from the operated-position detecting circuit when the AND signal from the AND circuit is not supplied and permitting the passage of the operated-position signal when the AND signal from the AND circuit is supplied.
