Abstract: A clip connector (A) includes an insulating housing (1) and a plurality of terminals (2) projecting from the housing (1). The housing (1) includes an outer surface (1a) for engaging a support member such as a printed board. The outer surface (1a) is irregular, including a plurality of projecting portions (12) and a plurality of retreating portions (13). Each of the terminals (2) includes a straight portion (20a) and a bent portion (20b). Each of the straight portion (20a) is formed with a through-hole (22) through which a resin for bonding the support member and the outer surface (1a) is applied.

Abstract: A protection cover for a thermal printhead includes an elongated body and two bosses formed on the lower surface of the elongated body. These bosses are arranged to slant with each other when the cover is fixed to the thermal printhead. Thus, the protection cover, which is originally flat, is caused to warp so that its central portion is raised above its end portions.

Abstract: A process for upgrading the characteristics of moisture containing coal which comprises drying coal until the water content reaches substantially zero, rapidly heating the dried coal to a molding temperature of from 200.degree. to 400.degree. C. within a time of from 1 to 10 minutes, compression molding the dried coal under elevated pressure, oxidizing the molded coal and then steaming said oxidized molded coal in saturated moisture at from 80.degree. C. to 150.degree. C. from 2 to 8 hours to provide a dry upgraded coal having a decreased tendency to self-ignite.
