Title: Ceramic substrate for electronic component
Inventor: MUTO TOSHIAKI
IPC: H05K3/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent such division failure as burr from occurring easily and to improve a yield by forming the depth of a site that crosses a primary slit in a secondary slit relatively shallower than the other parts. SOLUTION: A ceramic substrate 1 is provided with a plurality of primary and secondary slits 2 and 3 that orthogonally cross each other as a divided groove, and the depth of the secondary slit 3 being divided later is formed to be shallower at a site that crosses the primary slit 2, namely at a site corresponding to the end part of a simple substance after division, and is relatively deeper at the other parts. Therefore, when the ceramic substrate 1 is to be divided in a rod shape along the primary slit 2, the depth of the secondary slit 3 at a site that crosses the primary slit 2 is formed to be relatively shallower than the depth of the other secondary slit 3, thus preventing a bar bending failure where the secondary slit 3 is divided from occurring easily and improving a yield.

IPC: G02B27/28
Filed: 1988-04-13
Abstract: PURPOSE:To eliminate the difficulty in adjustment of an optical isolator and, at the same time, to reduce the size of the isolator further by forming holders for fixing a pair of polarizing elements of a magnetic substance. CONSTITUTION:A pair of holders 3 respectively provided with holes suitable for the outer shapes of a polarizer 1 and analyzer 2 which are polarizing elements so that the polarizer 1 and analyzer 2 can be put in the holes are formed of a magnetic substance and the polarizer 1 and analyzer 2 are put in and fixed to the holes. Then the polarizing elements 1 and 2 are respectively fixed to both sides of a permanent magnet 4 after the magnet 4 is magnetized and a Farady rotator 5 is inserted into the central part of the magnet 4. The holders are attracted by the magnet 4 and remain attracted unless external force is applied. Therefore, necessity of tentatively setting the constituents of this isolator in the course of optical axis alignment and 45 deg. adjustment is eliminated and, moreover, since the holders 3 maintain their attracted states after their positions are adjusted, the holders 3 can be fixed permanently by means of a resin bonding or metallic fusion. Thus the assemblage and adjustment of the optical isolator become easier and the whole volume of the isolator can be minimized. In addition, the angle of the optical axis can be adjusted easily.

Title: Arc welding machine
Inventor: KOMURA KOUJI
IPC: B23K9/12
Filed: 1980-07-08
Abstract: PURPOSE: To provide an arc welding machine which instantaneously stops short- circuiting current or prevents the same by so constituting the same that the short- circuiting of a wire and base metals is detected or forecast, and the feed speed of the wire by a variable speed motor is delayed instantaneously by this detected or forecast signal.  
     CONSTITUTION: Rollers 3 are revolved by a variable motor 4 to feed a wire 2 in the direction of base metals 5; at the same time, welding current is supplied from a power source 1, and the base metals 5 are welded. During this time if short-circuiting is likely to occur between the wire 2 and the base metals 5 owing to a certain cause, the voltage between the wire 2 and the base metals 5 drops sharply. In this case, the holding voltage of the arc is ≥10V, and for instance, when said voltage drops to ≤10V, the short-circuiting between the wire 2 and the base metals 5 can be forecast. A comparing control device 8 decreases the driving electric power of the motor 4 when the detected voltage drops to, for example, 5V, thereby operating the motor so as to lower the speed of the wire 2 instantaneously. Hence, arc length is increased and the short-circuiting of the wire 2 and the base metals 5 is prevented.
