Title: Arc welding method
Inventor: OI TOSHITSUGU
IPC: B23K9/08
Filed: 1985-03-12
Abstract: PURPOSE:To prevent the thermal and magnetic pinch hardening of an arc and to obtain sound welding structure by acting magnetic field on the arc and by swinging the arc. CONSTITUTION:An arc 3 is generated by impressing a voltage between a weld ing member 1 and electrode 2 and a magnetic field is acted on the arc 3 by magnets 4, 5 as well. The arc 3 is swinged in the direction (the directions of arrow marks 7 and 8) of the welding line vertical with the line of magnetic force according to Fleming's rule. The over-heating of the droplet to drop from the tip of the electrode 2 and the molten pool 9 formed on the welding member 1 of the immediately under part of the electrode 2 is thus prevented.

Title: Aqueduct maintaining environment for organisms
Inventor: HORI KENGO
IPC: E02B13/00
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide an aqueduct in which large dragonflys, etc., can lay their eggs and which is a good living environment for their larvae. SOLUTION: This aqueduct 1 is formed by successively installing a U-shaped corrugated steel plate 2 as aqueduct members. A porous material member layer 7 having an unevenness on the surface thereof is formed by pasting, etc., a fibrous material sheet at the bottom 5, the side surface 6, etc., of the U-shaped corrugated steel plate 2. Even if there is no pile of a soil and sand in the aqueduct, the large dragonfly, etc., can lay their eggs on the porous material member layer 7. Also, since a water penetrating member 3 can pile the soil and sand in the aqueduct by its constant soil and sand capturing function and soil and sand flowing out-preventing function, and also maintains a gentle flow without blocking the water flow completely, the aqueduct is further more suitable for the egg laying place and the living place for their larvae of the large dragonflys.

Title: Magnetic recording and reproducing device
Inventor: ISAKI MASATAKA
IPC: G11B15/08
Filed: 1980-04-15
Abstract: PURPOSE:To reduce power consumption by intermittently turning on the electric current to a light emitting element for detection of a light transmittable tape leader only when the magnetic tape reaches the terminal position. CONSTITUTION:When a VTR is set in constant speed running mode, source voltage is applied to feed terminals 36, 72. On letting-out of a magnetic tape, a supplying reel turntable 66 rotates and in response to a permanent magnet 68, a lead switch 70 turns to ON and OFF intermittently, then the number of revolutions of the reel turntable 66 is detected by a rotation detecting circuit 58. In a comparator 54, said number of revolutions is compared with the number of revolutions of a number-of- revolutions-set circuit 62. When it reaches the prescribed number-of-revolutions- range, a signal is supplied to an oscillating circuit 52, by which a lamp 30 is lighted intermittently by way of a transistor 42. The transparent leader tape is detected by a photodetector by way of the light of the lamp 30, by which the VTR is stopped. Thereby, the power consumption is reduced.

A tension body 4 is positioned at the center of this optical cable and the single groove units 3 are twisted around the circumference thereof, by which the optical cable is formed. The twisting direction is a right-hand twist reverse from the twist direction of the single groove units 3 at the time of twisting. As a result, the stable twists are maintained without untwisting of the regular spirals of the single groove units 3.

IPC: B65H19/26
Filed: 1987-03-06
Abstract: PURPOSE:To make it possible to reduce a loss of a film and to make it sure to start the wind-up of the film by forming a wind-up starting bias in a part of the film on one side thereof by use of a first cut, and by forming, at a relatively high speed, a second cut extending from the first cut and over the entire width of the film in the rear of a spool after the film is wound on the spool from the above-mentioned part only substantially one turn. CONSTITUTION:At first, a first cut 4 is formed in the leading end part of a film 1 by a length (l) with which the film is wound by substantially one turn on a spool 3, so as to form a wind-up starting small bias part 4a at an acute angle. Then an adhesive is coated on the spool 3 or the bias part 4 in the lower end section of the film, which is therefore wound up on the spool 3 so that a cut section formed by the first cut 4 is exposed in the rear of the spool 3. When a second cut is formed from the cut section 4, being extended over the entire width of the film at an acute angle, the film 1 is completely cut and split along two sides at 4, 5 into right and and left sections. The right section is wound on a preceding spool 2 while the left section is already started to be wound up from the small bias part 4a at the lower end part of the film and therefore, the film 1 is gradually wound directly and smoothly wound on a new spool 3 over the entire width of the film.
