摘要： A high-strength seamless steel pipe for oil wells excellent in sulfide stress cracking resistance which comprises, on the percent by mass basis, C: 0.1 to 0.20%, Si: 0.05 to 1.0%, Mn: 0.05 to 1.0%, Cr: 0.05 to 1.5%, Mo: 0.05 to 1.0%, Al: 0.10% or less, Ti: 0.002 to 0.05% and B: 0.0003 to 0.005%, with a value of equation “C+(Mn/6)+(Cr/5)+(Mo/3)” of 0.43 or more, with the balance being Fe and impurities, and in the impurities P: 0.025% or less, S: 0.010% or less and N: 0.007% or less. The seamless steel pipe may contain a specified amount of one or more element(s) of V and Nb, and/or a specified amount of one or more element(s) of Ca, Mg and REM. The seamless steel pipe can be produced at a low cost by adapting an in-line tube making and heat treatment process having a high production efficiency since a reheating treatment for refinement of grains is not required.

摘要： A tab (51) of a male terminal (50) is inserted into a main portion (11) of a female terminal (10). The tab (51) contacts a contact portion (16) of a resilient contact piece (15) to connect the female and male terminals (10, 50) electrically. A guiding portion (18) is formed on an inner surface of the main portion (11) for guiding the tab (51) inserted into the main portion (11) to a position where the tab (51) contacts the contact portion (16). The guiding portion (18) extends from a position before a contact position of the tab (51) with the contact portion (16) to the contact position while being inclined with respect to an inserting direction of the tab (51).

摘要： An input device, wherein the screen (18a) of a display device (18) is divided into two regions, a region (A1) and a region (A2), and the icon switch displayed in the region including the position of an invisible pointer (P′) is selected. Thus, one of an icon switch (1) and an icon switch (2) that are displayed on the screen (18a) is selected at any time. Consequently, the user will no longer have to watch the screen carefully and perform an operation for moving an instruction marker such as a visible pointer to a desired icon switch, for example as in conventional devices. Accordingly, the user can enter a desired instruction in a short time by selecting a desired icon switch in a short time.
