Abstract: PURPOSE:To provide a connection which is simple and sure in a system wherein an optical IC to and from which an optical signal is input and output is connected to a multilayer interconnection substrate which transmits the optical signal. CONSTITUTION:Ring-shaped metal pads 7 are formed around a light input and output part in an optical IC 6 and a light-incident and -radiating part in a multilayer interconnection substrate. The metal pads 7 are connected in a flip- chip manner by using a cylindrical solder 8. Thereby, the optical IC can be connected to the multilayer interconnection substrate, and an optical signal can be transmitted at the inside of the cylindrical solder 8. When the metal pads 7, the optical IC and the multilayer interconnection substrate are connected respectively to an electric interconnection layer 9, the connection, for electric signaluse, of the optical IC to the multilayer interconnection substrate and the connection, for electric-power supply use, to the optical IC can be achieved.

Title: Repeater and loop control method for wire and bar
Inventor: HAMAGUCHI AKIRA
IPC: B21B41/06
Filed: 1989-02-28
Abstract: PURPOSE:To improve the accuracy of sectional dimension of each wire and bar by making a looping device into the multistage configuration of up and down plural stages corresponding to each of plural wires and bars and setting mutually the passing route of each wire and bar at the approximately same length. CONSTITUTION:By a repeater 11, a looping device 14 is made into the multistage of an upper looping device 14A and a lower looping device 14B. Thus the loop of each wire and bar 13A, 13B doesn's interfere entirely and the passing route of each wire and bar 13A, 13B can be set mutually at the approximately same length. Then, the loop quantity of each wire and bar 13A, 13B can be controlled respectively based on its passing route. Therefore, the passing route of each wire and bar 13A, 13B can be always controlled appropriately. Simultaneously, the rolling bite timing of each wire and bar 13A, 13B at multiple rolling can be made in the same. Since the rolling load is always approximately constant by rolling with the same number, the difference of the deflection of roll 15 is prevented. As a result, the dimensional accuracy of the section is improved over the entire length of products and the yield is improved.

Abstract: PURPOSE:To obtain electroconductive sialon sintered product having high flexural strength and special and complicated shapes by sintering formed products from a sintering auxiliary-containing starting substances for beta-type sialon and Ti or a nitride and Si under specific conditions. CONSTITUTION:Starting substances for beta-type sialon containing a sintering auxiliary is mixed with 25 to 60vol.% of at least one selected from Ti and Zr nitride, 0.2 to 3.5vol.% of Si and the mixture is formed. The formed products are kept at 1,550 to 1,850 deg.C for 1 or more hours in a nitrogen atmosphere at normal or elevated pressure, then sintered at 1,700 to 1840 deg.C over 2 hours to give the subject sintered products. The use of Ti or Zr nitride is due to their high electroconductivities and high melting points with reduced adverse effects on sialon sintering. Si is readily wettable with the melt formed in sialon sintering to give a texture of higher homogeneity and reduced defects. Thus. the product gives a high strength matching those in hot press or HIP processing.
