Title: Wire bonding apparatus and its control method
Inventor: YOSHITOMI KIYOTAKA
IPC: H01L21/60
Filed: 1989-09-06
Abstract: PURPOSE:To realize a stable operation and to be hardly influenced by a noise by a constitution wherein a Z-axis position control operation is synchronized with respect to unstable elements at the time of a change of data of a comparator without a latch signal as well as the asynchronous time of a counter by utilizing pulse signals of an encoder. CONSTITUTION:An encoder A-phase signal 12 and an encoder B-phase signal 11 whose phases have been shifted by 90 deg. by using an encoder connected directly with a motor shaft are inputted. A sampling circuit 9 to which the encoder B-phase signal is input is constituted. Even when a counter reset signal is outputted early from a 16-bit comparator 4, the comparator waits until a data is stabilized by the sampling circuit 9, and a 16-bit counter 5 is reset. That is to say, the encoder B-phase signal is used as a sample pulse and a reset pulse is generated when the data has been stabilized surely by an output of the 16-bit comparator 4 and by an output of an AND circuit 9a. Thereby, the reset signal is outputted to the counter after the data has been stabilized surely.

Title: Semiconductor laser
Inventor: MATSUOKA NAOYUKI
IPC: H01S5/00
Filed: 1992-08-31
Abstract: PURPOSE:To obtain a high-output semiconductor laser, which has a small oscillation threshold value and is easily assembled and used, by a method wherein the laser is manufactured into a constitution, wherein the density of a current in the vicinity of a resonator end face and the density of a current in the part other than the part in the vicinity are made to differ from each other utilizing a difference between the work functions of metals, which are materials for electrodes, or a difference between the contact resistances of the electrodes to an epitaxial layer. CONSTITUTION:An epitaxial layer 32 is formed on a substrate 31 and first and second electrodes 35 and 36 are formed thereon in such a way that the electrodes are electrically connected to each other. Here, where the uppermost surface of the layer 32 is formed into a P-type, the work function of the electrode 35 is kept smaller than that of the electrode 36. Thereby, when a voltage is applied to the electrodes, the density of a current to flow in a semiconductor laser through the electrode 35 is smaller than that of a current to flow in the semiconductor laser through the electrode 36, the amount of a current in the vicinity of a resonator end face 34 is properly suppressed small utilizing a difference between these densities and the generation of heat in this part, in which the amount of the current is suppressed small, can be decreased. Moreover, as a current does not result in not being injected at all, an increase in a threshold current and the like can be also prevented from being generated.

Title: Heat exchanger
Inventor: ITO SHIGEO
IPC: F28F1/02
Filed: 1986-10-03
Abstract: PURPOSE:To improve the heat transfer performance of the heat exchanger by forming a plurality of ribs extending toward the flowing direction of a heat exchange fluid on the inner surface of a flat part in a flat tube and also forming depressions toward the inward at a predetermined interval in the flat tube thereby to change the direction of projection of ribs. CONSTITUTION:Since a gas coolant flowing within a coolant passage 6 of a flat tube 2 not only makes contact with the side wall and partition walls 7... of a tube 2 but also with ribs 8..., the contact area between the gas coolant and the tube 2 increases. In other words, since the heat transfer area increases, the heat transfer performance is improved. Further, since depressions 9... having a predetermined interval in the flow direction and mutually widened and opened ribs 8a and 8a are formed within the coolant passage 6, the gas coolant flowing within the passage 6 is disturbed in its flow. In conclusion, by the disturbance of the flow of the gas coolant, the gas coolant in contact with the side wall, partition walls 7... and ribs 8... of the tube 2 is replaced by new one. Consequently, the heat transfer performance is improved.
