Title: Method for drawing thin flux cored wire
Inventor: MATSUKUMA HITOSHI
IPC: B21C1/22
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To obtain a drawing method for a thin flux cored wire by which the wire breakage is not generated even at the time of high-speed drawing, which is excellent in productivity and whose cost is lower by drawing the wire making the reduction of area of each hole die not more than a specified possible limit reduction of area. SOLUTION: In this method, drawing is executed taking the reduction of area of each hole die as not more than the possible limit reduction of area which is expressed by the formula R=33.7-0.13X-0.002X<2> (In the formula, X is the total reduction of area.). When the diameter of the element wire of the wire is over 5 mm, the total reduction of area till the wire is drawn into a desired product becomes higher, the outer cover is hardened by working and the wire breakage is apt to generate, so it is desirable that the diameter of the element wire is 2-5 mm. When an iron powder rate becomes more, a slag agent and deoxidizerare relatively less and weldability and performance of weld metal are not satisfied, so the iron powder rate of filling flux is taken as 10-60%. From the viewpoint of elevating weldability, the filling rate of the flux is taken as, by weight, 15-20%.  In this way, the thin flux cored wire having higher flux filling rate and iron-powder rate is obtained.

Title: Image pickup device
Inventor: KAWAHARA ATSUSHI
IPC: H04N5/335
Filed: 1983-07-12
Abstract: PURPOSE:To obtain a high-contrast picture even in photographying of a high- speed object by setting the signal store period of each field so as to put the signal store period of the 2nd field close as much as possible to the signal store period of the 1st field. CONSTITUTION:For each signal charge store period of odd and even fields where continuous two fields are set in a pair, a period TeA is set for an odd field with coincidence secured between the rise of a vertical synchronizing signal and the timing. While a period TeB of the odd field is started immediately after the period TeA. Thus these periods TeA and TeB are almost continuous to each other. The exposure times of both fields for acquisition of signal charge are set close to each other to minimize the timing shift of exposure time. This produces no flicker nor blur with a reproduced picture of a high-speed object. Thus a high- contrast picture is obtained.

The tension by the lead wire 10 is exerted in the direction different from the vibrating direction of the diaphragm 3, and the vibration is rarely obstructed, leading to the sufficient pump performance.

CONSTITUTION:The width of tip parts of circular piezoelectric oscillators 1 and 2 which are polarized in the thickness direction and have electrodes on each main surface is reduced to less than the width of other part. A part of the oscillator 2 is larger than the width of the part corresponding to the oscillator 2, and a magnetic head 3 is attached at the tip part of a flexural oscillator. This flexural oscillator is attached to a rotary cylinder 6 via an attachment part 4. The flexural oscillator works with the part 4 and the tip part defined as a fixed terminal and a free terminal respectively. In other words, the tip part has displacement in response to the level of the applied voltage. Therefore, an optimum tracking state is obtained by the control of the applied electric field. With use of a circular or oval flexural oscillator, the length of the oscillator is made larger than a rectangular flexural oscillator to ensure a larger displacement compared with the rectangular oscillator.

Title: Bar code reader
Inventor: TSUBOI SEIKICHI
IPC: G06K7/10
Filed: 1987-05-26
Abstract: PURPOSE:To ensure the sure reading of bar codes even in case the position of the bar code is shifted in the direction crossing the scanning direction, by setting a spacer between a polygon mirror and a motor and forming an angle between the center line of the attachment hole of the polygon mirror and the center line of the rotary shaft of the motor. CONSTITUTION:When a polygon mirror 28 is attached to a motor 29, a spacer 34 is attached at the single side of the mirror 28 by a fixing means of adhesion, etc. Thus an attachment hole 28a of the mirror 28 has a tilt angle theta against a rotary shaft 29a of the motor 29. As a result, a scanning line 31 is set in the direction crossing the scanning direction within a single rotation of the mirror 28 since the mirror 28 is attached to the shaft 29a with an inclination. Thus a bar code 24 can be surely read even though the code 24 is shifted in said crossing direction form its standard position.
