Abstract: PURPOSE:To prepare a pipe excellent in grain boundary corrosion resistance and grain boundary stress corrosion cracking resistance, by applying cold processing to austenite stainless steel under a predetermined draft and, thereafter, applying heat treatment and final cold processing thereto under a specific conditions. CONSTITUTION:In preparing a pipe from austenite stainless steel, cold processing is applied to said stainless steel under a draft of at least 45% to mold a pipe which is, in turn, subjected to ageing heat treatment at 700 deg.C+t deg.C (t is 0-100 deg.C), that is, 700-800 deg.C. When the thickness of the pipe is 1mm., a heat treatment time is set to 10min or more at the time of t=0-50 deg.C and 5min or more at the time of t=50-100 deg.C. Next, softening annealing treatment is performed at 900- 1,050 deg.C for such a predetermined time that no grain boundary corrosion nor grain boundary stress cracking sensitivity appears after said annealing treatment and the succeeding final cold processing under a processing ratio of 15% or less and, after quenching, cold processing is succeedingly applied to the treated pipe under a processing ratio of 15% or less to finish the same.

Title: Time-division optical transmission system
Inventor: MORI MASAAKI
IPC: H04B10/524
Filed: 1981-02-20
Abstract: PURPOSE:To improve the efficiency of optical and electric mutual conversion by inhibiting the repetition of the conversion in the middle of transmission by transmitting information with light by an optical switch element through a time- division optical tramsmission system which uses optical fibers, and by receiving it by branching. CONSTITUTION:An optical switch element consists of an ultrasonicwave deflector AO and rod lenses RL1 and RL2, and light from an optical fiber (a) is normally passed through an optical fiber (b), but passed through an optical fiber (c) when a high-frequency input is applied. Light from a light source 11 is made incident to an optical fiber UF1 and is branched through the half-mirror UM1 of the line adapter TS1 of the 1st terminal equipment to be photodetected by a photodiode UP1, whose output is received by a communication control part UI/F1 through a receiving line UR1X to detect a time slot and a synchronizing signal. When the time slot 1 of the terminal arrives, a modulated signal is applied to an optical switch US1 through a transmitting line UT1X to modulated and transmit the light passed through the half-mirror UM1 to the next terminal, thus repeating reception and transmission one after another until a specified terminal.

Abstract: PURPOSE: To improve an assembling precision to reduce a deflecting defocus by making the plate thickness of the wall face of the full-circle hole of the first grid electrode plate in the part corresponding to the longer side direction of a CRT scanning face thinner than that in the part corresponding to the shorter side direction.  
     CONSTITUTION: A full-circle electron passing hole is provided in a grid. Plate thickness tH around the hole in the longer side direction A-A' section of a scanning face is made thinner than plate thickness tO around the hole in the shorter side direction B-B' section. In comparison with tH=tO, a beam scattering angle is reduced to 70% and a beam radius and the defocus in the A-A' direction are reduced in case of tH=0.5 tO. TH/tO=0.3 to 0.8 is proper, and a work efficiency is bad in case of tH/tO below 0.3. Thus, since the part processing is possible with a high precision, the assembling precision is improved, and the work is easy, and the deflecting defocus is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a heat insulating material suitably used for metal folded plate backing by improving the strength of the material while making use of the characteristic of a rayon fiber containing silicic acid. SOLUTION: A heat insulating material is made of a rayon fiber containing silicic acid of 95 to 50wt.% and a glass fiber of 5 to 50wt.% and this is formed to be a mat having a required thickness by needle punching. Thus, because of the mixture of the glass fiber, the deviating amount of the mat-like heat insulating material is small, a tensile elastic factor is large and thus the waist strength of the heat insulating material is increased. Also, itching (skin itching) caused by the mat-like heat insulating material made of the glass fiber is extremely small, even up to the level that no itching is felt in reality.
