Title: Joining structure and joint metal of wooden framework
Inventor: HARADA SHINJI
IPC: E04B1/58
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To obtain a joining structure having high strength by integrally forming a horizontal section placed on the top face of a column to the mounting section of a joint metal and inserting and fixing an inserting support section projected from the mounting section into a slit formed at the front end of a beam. SOLUTION: The mounting section 4 of a joint metal 3 is abutted against the side face of a column 1 consisting of square-shaped wood, and screws 19 are inserted and the mounting section 4 is fixed. The upper end of the mounting section 4 is bent in the horizontal direction at a right angle, a horizontal section 5 is formed integrally, and lag screws 17, 17 are screwed and the horizontal section 5 is fastened onto the upper end face of the column 1. An inserting support section 7 projected from the mounting section 4 is inserted into a slit 11 formed at the front end of a beam 2, and drift pins 14, 14 are driven and the inserting support section 7 is fixed.  Accordingly, since shear load is transmitted to the column as compressive force by the horizontal section 5, bolts having a large diameter need not be used, no large sectional breaking is generated in the beam 2, and a joining structure having high strength can be obtained.

Title: Apparatus for production, rewinder, winding and delivering method for optical cable
Inventor: TANJI HISASHI
IPC: G02B6/44
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent the local slackening and concentrating of tension fibers and to avoid increasing transmission loss even if these fibers are taken up on a bobbin of a small barrel diameter and are preserved by twisting an optical cable once every time this cable is wound on the bobbin. SOLUTION: The optical cable 1 longitudinally attached with the tension fibers 3 is wound around the bobbin 20 for delivery having the small barrel diameter. At this time, the optical cable 1 is held down by a take-off device 13 on its upstream side and is wound around the bobbin by a revolving guide 16 mounted at the front end of a revolving bar 17 on its downstream side. As a result, the optical cable and the barrel surface of the bobbin 20 for delivery or the already taken-up optical cable 1 come into contact with each other and the position compressed by the contact deviates in a circumferential direction and, therefore, the local slackening and concentrating of the tension fibers 3 do not arise. Consequently, the occurrence of microbends in the optical cable 1 and the increase of the transmission loss do not arise.

IPC: H01L23/12
Filed: 1994-09-06
Abstract: PURPOSE: To eliminate the malfunction of an LSI due to the fluctuation in the power supply potential or ground potential by a method wherein the connecting position of the LSI chip and a signal lead is attained so that the connecting region may be outside the mutual connecting region of the LSI chip and grounding layer.-power supply layer. CONSTITUTION: Within the connecting position of a connecting lead of an LSI lead and a grounding layer as well as the connecting position of the former and a power supply layer on a multilayer wiring substrate, the connecting regions 9 are respectively concentrated in the periphery of the LSI chip. At this time, the mutual connecting distance between the LSI chip and the grounding layer power supply layer is to be shortened. Besides, the connecting position of the LSI chip and a signal lead is attained so that the connecting region 10 may be outside the mutual connecting region 9 of the LSI chip and the grounding layer-power supply layer. Through these procedures, the malfunction of LSI due to the distortion or the fluctuation in the power supply potential or ground potential during the signal transition time can be notably eliminated.

Abstract: PURPOSE:To obtain high-purity lactic acid, by crystallizing an aqueous solution of impure magnesium lactate, dissolving the crystallized magnesium lactate in water, etc., adding sulfuric acid thereto, concentrating the solution, etc., separating lactic acid, removing MgSO4 remaining in the lactic acid with an ion exchange resin and separating and purifying the resultant lactic acid. CONSTITUTION:An aqueous solution of impure magnesium lactate is crystallized to give magnesium lactate crystals, which are then dissolved in water or made into a slurry form. Sulfuric acid is then added thereto and the resultant mixture is concentrated to form MgSO4 crystals, which are then separated from lactic acid. MgSO4 remaining in the lactic acid is then removed with a small amount of H- and OH- type or lactic acid type ion exchange resin to separate and purify the lactic acid. Thereby, the aimed high-purity lactic acid useful as food additives is obtained. EFFECT:Magnesium lactate in conditions of high lactic acid concentration can be treated with sulfuric acid and the concentration cost is low. The load on ion exchange resin and apparatus can be reduced as compared with the direct treatment of the magnesium lactate and cost is reduced.

IPC: G03B19/12
Filed: 1981-12-25
Abstract: PURPOSE:To reduce an error of an exposure time, which depends on mechanical accuracy, by releasing a delay means for obtaining an aperture stable time, immediately before a front curtain is released, in a shutter front curtain release mechanism of a single-lens reflex camera. CONSTITUTION:When a lever 14 releases a lever 12 by a release operation, a mirror and aperture driving mechanisms 12-16 execute mirror-up and stop- down.
