Title: Wire bonding process
Inventor: SHIBUYA YOKO
IPC: H01L21/60
Filed: 1985-01-25
Abstract: PURPOSE:To reduce any effect on a substrate in case of junctioning while preventing any cracking from occurring by a method wherein an end of wire is melted on case of junctioning a high strength wire and an electrode to junction a spherical part of wire and an electrode held at melted or half-melted state. CONSTITUTION:The space between a high strength wire e.g. an end of Cu1 and an electrode 2 mounted on a semiconductor chip 3 is impressed with charging voltage for arcing 10. At this time, the wire 1 apt to oxidation is shielded by inert gas 11 such as Ar and N2 etc. In case of arcing 10, the end of wire 1 is melted to form a spherical part 8 holding melted or half-melted state by the arcing 10 occurring between the spherical part 8 and the electrode 2. The spherical part 8 and the electrode 2 are junctioned as they are by means of ultrasonic oscillation. The hardness may be lowered by the junction of the spherical part 8 held at melted or half-melted state to prevent the hardening due to deformation in case of junctioning with the electrode 2 from occurring. Through these procedures, any cracking on substrate may be prevented from occurring even if relatively vely high strength metallic wire is utilized assuring excellent junction state.

Title: Gas refining device
Inventor: YAMADA HIROSHI
IPC: H01L21/31
Filed: 1991-02-04
Abstract: PURPOSE:To remove impurities selectively through condensation or absorption and supply refined gas of very high purity by a method wherein one part of high-pressure gas in a high-pressure gas deliverying unit is delivered directly into a feedback tube to permit the variable control of the capacity of adiabatic expansion cooling while the temperature of the adiabatic expansion cooling unit is permitted to be controlled at a required low temperature.

Title: Optical disk device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/09
Filed: 1984-01-27
Abstract: PURPOSE:To reduce seek error in a track access mode by providing intentionally a focus error when a traverse is carried out and therefore detecting the shift direction of a spot to a track. CONSTITUTION:A DC offset adder 7 is set between a focus error detector 4 and an objective lens driver 30. The adder 7 contains a DC offset changeover switch 71 and an adder 72. When the switch 71 is connected to the S1 side, the output of the adder 72 is equal to the output of the detector 4. Then the control is given to set the focus error of an objective lens 3 at O. The switch 71 is connected to the S2 side when a traverse is executed. In this case, a DC offset is applied to a focus control loop to set the focus error at a certain finite value. The outputs aOUT and bOUT of element bars 5a and 5b of a photoreceptor 5 are obtained as double-phase signals which are not equal nor opposite to each other. Thus the shift direction of a spot can be discriminated by checking the phase relation between both signals. That is, the directivity of the spot can be discriminated by checking whether the phase of the aOUT has adance to the bOUT or not.

IPC: F23J3/00
Filed: 1986-01-27
Abstract: PURPOSE:To stabilize the steam temperature of a heating surface on the downstream side, by a method wherein, with a soot blower started, only the specified heating surface of a heat exchanger is not cleaned, and a heating surface positioned on the upper stream side and a heating surface positioned on the downstream side are cleaned in conjunction with each other. CONSTITUTION:In a boiler device 1, by burning supplied pulverized coal by means of a burner 15, ash and soot are adhered and deposited to the heating surfaces of a furnace water wall part 12, a superheater 3, a reheater 4, and an economizer 5 to reduce heat transmission efficiency and bring a boiler into an unsound operating state. In order to blow off adhered and deposited ash and soot, a soot blower 27 depending upon each heat exchanger is disposed. When the soot blower 27 is started to clean a heating surface, the endotherm of the heating surface is increased, and a gas temperature at an outlet is decreased. However, since, after a heating surface having the high degree of synthetic state priority 209 is cleaned, a heating surface having the low degree of synthetic state priority 210 is also cleaned in linkage, endotherm of a heating surface on the downstream side can be prevented from reduction.
