Filed: 1987-04-27
Abstract: PURPOSE:To realize the miniaturization and to reduce cost by a method wherein an insulating film is formed on the surface of a wire which electrically connect a semiconductor integrated circuit having a bonding pad to a lead frame with a view to preventing a defect due to a short-circuit of the bonding wire and in order to relax a limiting condition for designing the semiconductor integrated circuit and the lead frame. CONSTITUTION:An insulating film is formed at an external circumference of a bonding wire 3 by using a surface oxidation method, an evaporation method, an immersion coating method or the like. As a material for the insulating film, a metal oxide film or a plastic material can be used. An insulating film 3a is bonded by using a method that it does not come into contact with an IC chip or a junction face of a lead frame during a bonding operation. In addition, a junction part of the insulating film 3a is exfoliated, by heat, ultrasonic waves or the like during the bonding operation. Because the insulating film 3a is formed on the bonding wire 3 in this manner, no electrical short-circuit is caused due to the insulating film 3a even when the wire 3 comes into contact with 7 an end 1a of the IC chip; accordingly, it is possible to narrow a gap for bonding use and the chip can be miniaturized. Furthermore, a designing condition to decide a relation between the lead frame and a pad for the IC is relaxed; an extent to use the lead frame commonly with the IC chip of different sizes where a pad is arranged is expanded and it is possible to reduce cost.

Title: Disk recording medium and its production
Inventor: SO KYON KIM
IPC: G11B7/24027
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To compensate stress caused by disturbance such as centrifugal force with residual stress to suppress vibration and to enable fast rotation by joining an annular reinforcing member having a different coefft. of thermal expansion from that of a disk to the inner circumference or outer circumference of the disk and cooling the outer circumference part to a lower temp. than the inner circumference part so as to allow the residual stress giving tension to be present. SOLUTION: The disk recording medium is equipped with a reinforcing member 12 in the center part of the disk 10. The reinforcing member 12 as heated to a higher temp. than normal temp. is joined to the inner circumferential part of the disk 10 at normal temp. The reinforcing member 12 joined to the center of the disk 10 shrinks with temp. decrease and produces residual stress to give tension in the radial direction of the disk 10. When tension is added in the radial direction of the disk recording medium, vibration of the disk recording medium is suppressed, and as a result, the disk recording medium can be rotated at a faster rate than the limit. Thus, the transmission rate of information on the disk recording medium can be improved than the limit.

Title: Method of detecting oxygen starvation for gas apparatus and detector
Inventor: NAKAURA MASAAKI
IPC: F23N5/24
Filed: 1978-08-26
Abstract: PURPOSE:To prevent incomplete combustion under the oxygen starvation by means of a gas detector using pilot burners different with combustion condition depending on a temperature falling property that the flame temperatures of the two burners vary with a drop in the oxygen concentration. CONSTITUTION:The flame 2 of one pilot burner A is so set at such a high temperature in combustion that there is a clear boundary between the inner and outer flames while the flame 2 of the outer pilot burner B is set at a such low temperature that the boundary are kept unclear between the two flames. A thermocouple 5 is inserted into the outer flame of the burner A higher in the temperature while a thermocouple 5' is inserted into the inner flame of the burner B lower in the tmperature whereby the temperatures of the two flames 2 and 2' are respectively converted to a thermal electromotive force. When the difference between the two thermal electromotive force is detected, as the input, this activates a magnet valve 7. As two magnet coils 6 and 6' are wound in the opposite direction to each other, the difference in the flame temperature is detected as the difference of magnetic flux. This goes to zero at a given oxygen concentration. In this manner, the valve is closed to halt the gas supply.
