Title: Capillary for optical fiber connector and its production
Inventor: HAYAKAWA MAKOTO
IPC: G02B6/36
Filed: 1994-06-09
Abstract: PURPOSE:To provide a capillary for an optical fiber connector of a low working cost and a process for producing such capillary. CONSTITUTION:This capillary consists of a cylindrical sintered compact of ceramics and has a straight hole-like fine hole 3 having the bore slightly larger than the outside diameter of an optical fiber for insertion of the optical fiber and an end face for connection at which the fine hole 3 is opened. The inside surface of the fine hole is substantially a baked surface. The man-hours for grinding of the inside surface of the fine hole are, therefore, made drastically smaller than the man-hours for working the conventional capillary for optical fiber connectors. The production cost is thus reduced.

Filed: 1993-06-23
Abstract: PURPOSE:To obtain a method for measuring the output signal change of a semiconductor integrated circuit which can accurately measure enable time or disable time. CONSTITUTION:A load capacitor 4 is charged and a measurement voltage VO is set to VDD. Then, an output enable control signal bar OE is inverted into 'H', an output buffer 1 is disabled, electric charge charged to the load capacitor 4 is discharged through a constant current source 8, and then the measurement voltage VO is reduced from VDD. Then, the time it takes from the timing when the output enable control signal bar OE changes to 'H' to the timing when the measurement voltage VO is reduced from VDD by 0.3V is measured as a disable time TPHZ. Therefore, by setting the supply current of a current source required for charging and discharging of load capacity to a fully large value, disable time with an improved time can be measured constantly.
