Title: Stem for semiconductor device
Inventor: KOGURE NAOSHI
IPC: H01L21/60
Filed: 1989-01-12
Abstract: PURPOSE:To increase the electrostatic breakdown strength of a stem by a method wherein a pad for metal wire bonding use is constituted of a double layer consisting of an iron layer, which is the surface of the pad, and a copper layer, which is the lower part of the pad. CONSTITUTION:A copper post 3 is soldered on a stem base 1 made of iron, a heat sink 4, which is made of high-resistance Si and has each conductor layer 9a and 9b on its upper and lower surfaces, is soldered thereon and a semiconductor laser pellet 5 is fixed on this layer 9a. Moreover, an iron layer 7 is provided on part of the surface of the post 3 and a bonding is performed by a gold bonding wire 6b from this layer 7 to a lead 2. Moreover, a bonding is performed by a gold bonding wire 6a from the pellet 5 to the layer 7. As a result, the heat of the pellet 5 passes through the Si heat sink and the copper post and is efficiently dissipated outside of the stem base. In such a way, by covering part of the stem with a metal layer having a large hardness, a wire bonding is facilitated without disturbing the heat dissipation of the pellet and the electrostatic breakdown strength of the stem can be increased.

Title: Pickling method for preventing die galling of hot rolled steel sheet
Inventor: HONDA TADASHI
IPC: C23G1/08
Filed: 1984-01-19
Abstract: PURPOSE:To obtain a pickled and hot rolled steel sheet having good resistance to die galling by pickling the hot rolled steel sheet by using an aq. soln. contg. a specific compsn. amt. of hydrochloric acid and oxidizing agent. CONSTITUTION:A hot rolled steel sheet is pickled to prevent die galling by using an aq. soln. contg. 10-15wt% hydrochloric acid and 5-10% oxidizing agent so as to contain <=20% total acid and consisting of the balance water and inevitable impurities as a pickling soln. in the stage of pickling the hot rolled steel. The longer treating time for pickling and weaker effect of descaling are resulted if said hydrochloric acid concn. is <10% and there is no room for adding the oxidizing agent if the concn. exceeds 15%. Sulfuric acid, nitric acid, hydrogen peroxide, potassium dichromate, perchloric acid, hydrofluoric acid, etc. which dissolve by reacting with scale are suitable for the above-mentioned oxidizing agent. The melting of the ferrite after descaling is accelerated and pitting arises if the amt. thereof exceeds 10% and the lower remaining effect of carbon and the easy tendency to galling results at <5%. The pickling time is longer and the pickling is disadvantageous if the total of the acids exceed 20%.

Title: Manufacture of copper-plated laminated board
Inventor: SUZUKI SHIGERU
IPC: B32B15/092
Filed: 1990-01-17
Abstract: PURPOSE:To improve plating adhesive properties and heat resistance of a high frequency polyethylene copper-plated laminated board by incorporating 10-60wt.% of a filler selected from silica, calcium carbonate, alumina and titanium oxide as a filler in a silane modified polyethylene resin film. CONSTITUTION:A silane modified polyethylene resin film 1, a silanol condensed catalyst-containing epoxy resin prepreg 2 and a copper foil 3 are superposed, press-molded and crosslinked to obtain a copper-plated laminated board. Since the polyethylene resin particularly has smaller polarity of plastics, its adhesive properties of a plating metal are not sufficient. Therefore, the adhesive properties of the plating metal are improved by mixing silica, calcium carbonate, alumina or titanium oxide as an inorganic filler, and its mixing ratio is suitably 10-60%. Thus, the heat resistance, the adhesive properties of the plating metal such as through hole plating are improved while maintaining high frequency characteristics at a high level.

Abstract: PROBLEM TO BE SOLVED: To improve the balance between the corrosion resistance and the spalling resistance of a refractory for continuous casting, to reduce the cost with the improvement of durability, to stabilize an operation and to improve the quality of a cast slab by making a specific value or higher of the ratio of the thermal expansion coefficient in the axial direction to the thermal expansion coefficient in the peripheral direction of a graphite-containing material applied to the immersion part of a long nozzle or the powder line part of an immersion nozzle. SOLUTION: In the powder line part of the immersion nozzle 2, in the most case, the crack 3 is developed in the axial direction. This means that the intensity of thermal stress developed in the peripheral direction side is larger than that developed in the axial direction side. Therefore, what the thermal stress in the peripheral direction side is reduced, is related to restrain the development of crack caused by the spalling. In the case of using (a) for thermal expansion coeffient in the axial direction and (b) for the thermal expansion coefficient in the peripheral direction of the graphite-containing material applied to the immersion part of the long nozzle or the powder line part of the immersion nozzle 2, a/b is made to >=1.1.

Title: Printed board
Inventor: KOBAYASHI MANABU
IPC: H05K1/02
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce 'icicles' appearing on a screw connection of a printed board and lessen electrical and mechanical defects, by removing solder on the screw connection to such an extent that spaces may be formed evenly on the entire surface of a screw connection region. SOLUTION: Solder is removed so that spaces may be formed evenly on the entire surface of a screw connection region 10. Spaces (regions having no solder) 40 are formed by preliminarily applying resist as in other regions A, B where no wiring is conducted. By this method, when pulling a printed board 1 out of a solder bath at a specified angle, solder does not attach to the resist applied regions of the screw connection region 10 and a quantity of solder attaching to the region 10 is reduced and part of the solder which could be 'icicles' is decentralized and, therefore, the height of the 'icicles' is reduced. Even if there are sections left over as 'icicles', those 'icicles' are formed evenly on the entire surface of the screw connection 10, and the solder is brought into contact with a rear face of a screw at several points, thereby obtaining a stable electric contact.
