Title: Region for bonding wire to substrate
Inventor: JIYON HOITEIA SUREMONZU
IPC: H01L21/60
Filed: 1990-02-27
Abstract: PURPOSE: To bond wires to a substrate with keeping them highly conductive by making them of a fifth material reactive with a first material of which the substrate is made but nonreactive with a fourth material at a region for bonding the wires to the substrate. CONSTITUTION: Sputtering is caused between an anode 10 and W cathode 12 to bombard the cathode 12 with heavy ions 14 and sputter W atoms 16 on an Al foil 18, thereby forming a sufficiently thick W layer 28 on the foil 18. Power is delivered from wires 20 and a vertical support 24, and the vertical support 24 rotates a horizontal support 22 so that an Au cathode 26 lies on the orbit of ions 14. The power is returned to form Au over the W layer 28. An Au foil 42, a W foil 28 and an Al foil 18 form a 3-foil combination 44, and it is removed from a vacuum vessel 32, reversed and laid on an Au substrate 46.

Abstract: PURPOSE:To detect the deviation between a focus of an objective lens and an information recording face by arranging a transmission type or a reflection type rotary grating between a beam splitter and a photodetector so as to detect the diffracted light from the rotary grating. CONSTITUTION:The light from a light source 4 is collimated by a collimator 9 and collected on the information recording face 1 and the reflected and diffracted light from the recording face is led to a detection system by a beam splitter 3 after passing through again the objective lens 2. In this case, when the information recording face 1 of the optical disc is coincident with the focus of the objective lens 2, when the disc is after the focal position and before the focus, then a collimated light, a convergent light and a divergent light are made respectively incident to the diffractive grating 12. As a result, in extracting the output difference from the 2-split photodetector 11 through an electric differential amplifier 13, the deviation of the focus of condenser lens is detected. Further, the information signal of the optical disc is reproduced by summing signals from the split photodetector 11.

Filed: 1986-03-10
Abstract: PURPOSE:To prevent self-excited vibration and allow high-precision machining and high-speed machining via a high-pressure machining liquid by providing an elastomer having a spring and a damper and a vibration absorbing device made of a movable mass on a machining liquid feed nozzle supporting mechanism. CONSTITUTION:A vibration absorbing device 50, in which a movable mass 11 is connected to a frame 13 constituted of four flat plates via a cylindrical elastomer having a spring mechanism and a damper, is fixed to an arm 6 supporting a machining liquid feed nozzle 5 through a screw hole 15. When a fluid force is applied to the nozzle 5 during discharge machining, self-excited vibration is generated. However, the damping performance of the arm 6 is improved via the spring action and damping effect of the movable mass 11 and the elastomer 12, thus self-excited vibration due to the fluid exciting force is prevented. Accordingly, vibration can be prevented from occurring even if the pressure of the machining liquid is increased, thus high-speed machining can be performed without decreasing machining precision and deteriorating the machined surface.
