Patent JP-S6116825-A (JP)
Title: Production unit for record
Inventor: ANRI AMORI
IPC: B29C45/34
Filed: 1985-05-02
Abstract: Two matrices (10, 11), each bearing modulation to form a microgroove disc record, are fixed to half-moulds (4) by means of sleeves (23, 24) having first and second fixing flanges (41, 42) which extend into the gap between the matrices. One of the flanges (46) is an annular blade whose inner radial surface (47) defines the edge of a moulded disc and whose thickness is slightly less than that of the moulded disc. Formed integrally with, or attached to, the blade is a group of radially outwardly extending lugs (49) which are attached to the body of its associated sleeve 23. The other flange comprises a second group of lugs (42) mounted to the body of its associated sleeve (24) radially outward of the blade such that the second group of lugs (42) may lie in the spaces between the first mentioned group of lugs (49). The thickness of the lugs (42) of the second group determines the thickness of the disc and the thickness of the lugs of the first and second groups differs, to determine a gap for escape of air along the first flange (41). Spaces between the groups of the two interlaced lugs (49, 42) permit a controlled escape of air from the periphery of the record without the formation of peripheral flash.

IPC: C21C7/06
Filed: 1979-07-26
Abstract: PURPOSE: To prevent the formation of bubbles and to increase the yield of casting in continuous casting of billet etc. with small section, by charging Al on the dummy heat at the start of casting, then by pouring molten steel into the mold.  
     CONSTITUTION: In casting billet, bloom etc. of small section by continuous casting method, 100g/ton molten steel is charged previously on the dummy bar head at the start of the casting. Then molten steel is poured into the mold, and the dummy bar head is taken out thereby casting small size billet or bloom continuously. Continuous casting is performed while adding as usual 300g/ton molten steel. Hereby decrease in the yield of cast billet due to the formation of bubbles is prevented because very few bubbles are formed when the cast product solidifies.

CONSTITUTION:When filament electrodes 34a, 34b of a discharge lamp 34 are broken, large abnormal voltage is generated between both ends of a series circuit by capacitors 37, 38. When a voltage level of a capacitor 40 is increased becoming higher than break over voltage of a constant voltage diode 41, the diode 41 is conducted to emit light by a light emitting diode 42D.
