Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of malfunction such as deterioration of reliability on contact by preventing adhesion of foreign bodies to a fixed contact.  <P>SOLUTION: A partition wall 20 for partitioning between a magnetic pole 1a of an iron core 1 and the fixed contact 9 and a movable contact 8 is provided in a case 13. In comparison between a case of providing the partition wall 20 in the case 13 and the conventional case of providing the partition wall in a body block 11, since dimensional limitation is looser in the case of providing the partition wall in the case 13, a sufficient thickness is secured and while height is increased to narrow a clearance g1 between a tip of the partition wall 20 and the body block 11 in comparison with a clearance g0 in the conventional case. As a result, passing of the foreign bodies such as the abrasion powder, which is generated by a collision of an armature 5 with the iron core 1, through the clearance g1 becomes hard, and adhesion of the foreign bodies such as the abrasion powder to the fixed contact 9(and the movable contact 8) is prevented to prevent the occurrence of malfunction such as deterioration of reliability on contact.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To enhance durability of LD (semiconductor laser device) in order to prevent deterioration for an over-current as a surge-current impressed from an external side.  <P>SOLUTION: This optical semiconductor device comprises an active layer 5 which is sandwiched between clad layers to emit the light beam, a current block layer 3 which limits the current injected by an electrode, and a stripe 10 to concentrate the current injected by the electrode to an active area of the active layer which are provided on a substrate. Since an optical semiconductor device chip is thinner in the wire bonding side than the stripe side in this optical semiconductor device, a capacitance in the wire bonding side is set larger than that in the stripe side so that the higher frequency element of surge current is never supplied to the stripe side which makes contribution to the emission of light.
