Patent JP-S6360586-A (JP)
Title: Semiconductor laser
Inventor: HINO ISAO
IPC: H01S5/00
Filed: 1986-08-29
Abstract: PURPOSE:To obtain a laser having no astigmatism, oscillating at a fundamental transverse mode and generating small noises by forming an optical guide mechanism in the horizontal cross direction in the vicinity of an optical outgoing end surface in a striped oscillation region in an index waveguide type and shaping a residual section in a gain waveguide type or the combination type of a gain waveguide and an index waveguide. CONSTITUTION:A region 11 positioned at 50mum from the outgoing optical end surface of a stripe region 10 is formed in an index waveguide type region having a distributed index equivalent dn the horizontal cross direction of an active layer 3. A residual section 12 is shaped singly in a gain waveguide region in which a current injection limiting region is formed by an inversion layer 5. It is because the thickness of p-Ga0.5In0.5P on the outside of the stripe region 10 is thickened as 1mum in the gain waveguide region 12 and therefor a distributed index is not shaped in the horizontal cross direction. The index waveguide type region 11 takes length of approximately 20mum or more from an end surface. An element manufactured in this manner functions as a low-noise laser having no astigmatism and oscillating at a fundamental transverse mode.

Inventor: HONDA KOZO
IPC: H02P21/00
Filed: 1994-08-30
Abstract: PURPOSE: To make it possible to reduce power loss more as compared with a case where required torque is output without intensifying a field system, by issuing a command to correct reference field current to increase it by a required amount when large torque is required. CONSTITUTION: When an induction motor 11 requires large torque, a higher level controller 15 controls the switching circuit 21 in a field reference correcting circuit 19 so that it will select a rate of increase K and add it to a muliplier 22. The multiplier 22 multiplies the reference field current of a field reference circuit 18 by the ratio of increase K, and the reference field current is thereby increased in a preset ratio. The result of increase is added to a vector control unit 24 through a rate circuit 23. The vector control unit 24 vector-synthesizes torque current component and field current component based on reference torque current from a speed control circuit 14 and reference field current from the field reference correcting circuit 19 to obtain resultant current.

Title: Device for wire bonding
Inventor: KAMIJIYOU ATSUSHI
IPC: H01L21/60
Filed: 1982-11-24
Abstract: PURPOSE:To enable to form the stabilized ball even in a nitride or inert gas flow by a method wherein a pipe, with which nitride or inert gas is flown downward along a capillary, is provided. CONSTITUTION:As nitrogen or inert gas runs in the pipe 7 along the capillary 2, the direction of electric discharge and nitrogen or inert gas flow are brought in parallel with each other. As a result, the formation of a ball can be performed in a stabilized manner without giving an effect on the electric discharge. Also, as a nozzle and the capillary 2 can be moved in one body and nitrogen or inert gas is flown from the part located very close to the ballup position, the surrounding air is not engulfed at the ballup position, and excellent nitrogen or inert gas atmosphere can be formed. Thus, nitrogen or inert gas atmosphere can be obtained in a simple but reliable manner and the ballup can also be performed in a stabilized manner, thereby enabling to perform a reliable bonding at a high speed using an easily-oxidized gold wire containing an easily-oxidized element.
