Title: Digital counting rate meter
Inventor: MOGI KENICHI
IPC: G01T1/17
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To measure a counting rate by removing noise to prevent erroneous counting due to noise. SOLUTION: A counting rate is measured by normal measuring means with a feedback type counting rate meter comprising an up/down counter 1, a pulse generator 2 and a calculator 3. A counter 4 counts a measured pulse at a predetermined sampling frequency, and if a current count value exceeds the upper limit of tolerance compared to a previous count value, the counting rate just before that exceeding is assumed as a counting rate to be found, and if it is within the tolerance, the counting rate is found by a re-tray calculation which calculates the counting rate for correction, and after it exceeds the upper limit of tolerance for a predetermined continuous period, measurement is done by normal measuring means. When it is within the tolerance or after re-try calculation, the counting rate is found, based on the comparison result with current count value.

Title: Ultrasonic welding apparatus
Inventor: YOSHINO SOUICHI
IPC: B29C65/08
Filed: 1979-07-11
Abstract: PURPOSE:To prevent a material to be welded of a poor heat resisting characteristics from being deteriorated, by rapidly transmitting welding heat, which is generated at a tip, to a horn so as to cool the tip. CONSTITUTION:The heat generated at an overheated tip 6 during an ultrasonic welding operation is transmitted rapidly to a horn 5 through a heat pipe 9. An amount of heat Q1 is absorbed at an end portion of the heat pipe 9 due to the evaporation (arrows a) of a working liquid 12, and transferred in a direction of an arrow b. The evaporated working liquid is then condensed as shown in arrows c at the other end portion of the heat pipe 9 to radiate an amount of heat Q2. The condensed working liquid is returned to the original position as shown in an arrow d by a capillary action. The heat is transferred according to this heat cycle. Owing to the heat pipe installed in the horn and tip, an increase in the temperature of the tip can be prevented, so that the generation of welding heat can be minimized. Therefore,  the thermal deterioration of a material due to the welding can be minimized.
