Title: Integrated circuit magazine housing mechanism
Inventor: KOBAYASHI TSUNEO
IPC: B65G57/30
Filed: 1985-08-22
Abstract: PURPOSE:To make a magazine to be housed unnecessary to be raised higher than a housing position as well as to prevent a crack in IC ceramics from occurring, by forming a stopper into an almost circular form or a circumferential surface where a radius of curvature increases or decreases. CONSTITUTION:A sectional stopper 20, whose upper circumferential surface is formed into a circular form, is pivotally attached to a side wall of an opening part 3a inside each strut 2 at both sides of a stacker 10 at a central position of a circular arc by a pin 8, while a return spring 21 is stretched across between the stopper pin 22 installed in a sectorial side part 20b and the strut 2. When a magazine 5 is pushed up by a push-up housing mechanism 4, the magazine 5 goes up as being engaged, at both ends of it, with the sectorial side part of the stopper 20, whereby an upper circumferential surface end part 20a is retracted to the side of an inner wall of the strut 2. When the magazine 5 goes up to a housing position at that point over the tip side of the circumferential surface part 20a, the stopper 20 returns to its position as the circumferential end part 20a is sliding on the part bottom of the magazine 5 by action of a spring 21. With this constitution, since a vertical variation at the time of housing is no linger produced there, a crack in ceramics is preventable, thus a housing rate is speeded up.

Title: Analog-to-digital converter
Inventor: NAIKI TAKASHI
IPC: H03M1/12
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To decrease the power consumption of an A/D(analog/digital) converter by preparing a conversion period and a pause period to make an A/D converter perform an A/D operation in the conversion period and to stop the operation of an A/D conversion part, etc., by means of a pause signal and a switch in a pause period respectively. SOLUTION: The conversion start triggers TG are outputted from an interval counter 2 at a fixed time interval, e.g. one second. Based on the TG, a control part 4 keeps a pause signal STBY at a high level until the A/D conversion is over at an A/D conversion part 8 and then at a low level until the next TG is inputted. A conversion period is secured when the signal STBY is kept at a high level, and a pause period when a timing control circuit 3, a reference voltage generation circuit, etc., stop their operations is secured when the signal STBY is kept at a low level. The reference voltage generation circuit has the intermittent operations and virtually consumes no current in the pause period. Thus, the power consumption is decreased for an A/D converter.
