Abstract: A sewing machine includes a plurality of needle bars. One of the needle bars can be selected and reciprocally driven so as to stitch a desired embroidery pattern. The sewing machine has a common setting mode and an individual setting mode, which permits various operating conditions to be either commonly set for all the needle bars or individually set for one or more of the needle bars. If the common setting mode has been selected, the same operating conditions can be commonly set for all the needle bars. If the individual setting mode has been selected, the operating conditions can be set individually for each needle bar.

Abstract: A thread cutting device in a sewing machine includes a movable knife which is movable across a space between a throat plate and a shuttle positioned below the throat plate so as to perform a thread cutting operation. A lower thread retreating lever is movable from a waiting position to an operative position for retreating a lower thread taken out from the shuttle to a position out of a thread cutting orbit of the movable knife. The thread cutting device is operable in either a thread cutting mode for cutting both an upper thread and a lower thread or a thread cutting mode for cutting only the upper thread by selectively positioning the lower thread retreating lever at either the waiting position or the operative position during the operation of the movable knife. An actuator and an interlocking mechanism between the actuator and the lower thread retreating lever are provided for driving the lower thread retreating lever. The actuator and the interlocking mechanism are positioned rearwardly of the shuttle.

Abstract: An implant is produced by coating a core material with a calcium phosphate type compound and converting the coating layer into an apatite type ceramic layer by a hydrothermal treatment.

Abstract: A transcutaneously implantable element in which at least a portion thereof in contact with the cutaneous tissue of a living body is composed of a ceramic material comprising, as the main raw material, at least one member selected from the group consisting of hydroxyapatite, tricalcium phosphate, and tetracalcium phosphate, and which comprises (a) an electrically conductive member for electrically connecting the interior and exterior of the living body to each other or (b) a through hole for mechanically connecting the interior and exterior of the living body to each other.This transcutaneously element can be semipermanently and safely used in a living body without causing any undesirable bacterial infection, bleeding, and background noise.

Abstract: A novel water dispersible cold rolling oil composition for aluminum and aluminum-containing alloys comprising (a) one or more lube oil components selected from mineral oils, higher fatty alcohols, higher fatty esters and higher fatty acids, and (b) a specific water soluble cationic or amphoteric polymer compound. The composition provides a cold rolling lubricant which possesses excellent cooling capability, rolling lubricity and circulation stability, and can be readily controlled in operation.
