Title: Fabrication of decorative trim band
Inventor: ROBAATO ANDORIYUU ZOORAA
IPC: B29C48/21
Filed: 1977-05-25
Abstract: The disclosure relates to a method of making a trim strip comprising the extrusion of a vinyl material to form a body which is so shaped that it can be confined in a peripheral slot in a roll, thereby to permit substantial pressure to be applied on the extruded body and a decorative strip by a mating roll. The top portion of the extruded body has side extensions which are supported by the edges of the recessed roll; thus, substantial pressure can be applied on the entire top of the decorative surface strip and the body to produce an adhesive bond or a bond by heat sealing. After the body is cooled, it is advanced through a number of aligned milling cutters to machine aligned recesses in the sides of the body to produce a retention cutout. After being machined to depth, the trim strip is advanced through a pair of grinding wheels to accurately form and space the recesses. During the extruding operation, a coated wire may be embedded within the body in the conventional manner.

Title: Method for correcting dead time
Inventor: WAKIYAMA YOSHIHIRO
IPC: G01T1/17
Filed: 1986-03-17
Abstract: PURPOSE:To reduce an error in correction by obtaining a dead time by adding the time from the rise of the output signal of a slow amplifier to the attainment to a peak as an additional time to the processing time of the output signal of the slow amplifier which is generated after a pulse signal is inputted from a fast amplifier. CONSTITUTION:An A/D converter or linear amplifier processes the output signal B of the slow amplifier which is generated after the pulse signal A from the fast amplifier is inputted and the time corresponding to the time TC+TP obtained by adding the time TP from the rise of the output signal of the slow amplifier to the attainment to the peak as the additional time to the signal processing time TC up to the passing of the output signal is regarded as the dead time TD. Consequently, even if a leading pile phenomenon occurs, the dead time TD ends the additional time TP after the processing time of the signal after its leading piled-up state, so a proper dead time correction is made.
