Title: Manufacture for pipe having groove in internal surface
Inventor: IEDA NORIO
IPC: B21C1/22
Filed: 1981-11-14
Abstract: PURPOSE:To draw deep grooves by a relatively small drawing force, by using drawing dies having special shapes and fluting the internal surface of a metallic pipe by drawing work. CONSTITUTION:A metallic pipe 18 is drawn to the rigit side by passing it  through dies 10 and 12 to contract its diameter into the 1st small diameter pipe  20 and successively into the 2nd smaller diameter pipe 22. In this case, a supporting plug 24 is connected to a plug 32 by a rod 34 at a fixed distance apart,  and the connected plugs are arranged in the inside of the pipe 18. When the 1st  small diameter pipe 20 is passed through the die 12, grooves having the prescribed forms are formed in the internal surface of the pipe 20 by a grooved  part 36 grooved in the surface of the plug 32. Draft parts 40 having respectively  the width A are formed at the end of a drawing hole 38 of the die 12 to prevent  them from contacting with the outer surface of the pipe 18 in drawing work,  then a required drawing force is remarkably reduced because the contacting surface is decreased as much as said draft parts, and the drawing is efficiently performed.

IPC: G01S7/02
Filed: 1982-10-20
Abstract: PURPOSE:To enable certain and precise selection, in a radar for generating circular polarized wave receiving output and linear polarized receiving output, by selecting only the circular polarized receiving output while comparing both polarized wave receiving outputs with respect to a same partial region.

Abstract: PURPOSE:To ensure the detection of the defects of a mask, by forming a light sensitive layer, which has non-light transmitting property or semi-light-transmitting property, exposing and developing the pattern of the mask to be checked, and yielding a picture signal having good contrast. CONSTITUTION:On a light transmitting substrate 1 such as glass, a non-light transmitting or semi-light transmitting thin-film light-sensitive layer 2 is formed by using resist and the like including a coloring matter. The substrate 1 is mounted on an image forming part of an exposing device. The pattern of a mask to be checked 3, in which circuit patterns 3a and 3b are formed, is exposed and developed. Thus a light sensitive layer 4 of the pattern corresponding to a transfer pattern is obtained.

Filed: 1984-09-01
Abstract: PURPOSE:To obtain a compact system capable of selecting and taking out for a short time by sampling detecting a pointer output in a regulating device, and selecting one having remainder of large quantity. CONSTITUTION:A binary counter of stack pointers 31-34 inputs a signal of 'yes' or 'no' on an empty condition, more than half, more than 3/4 or a full condition to a priority decision circuit 9, namely, sampled result is inputted.
