Filed: 1985-10-14
Abstract: PURPOSE:To enhance air cooling effect with small air blowing power by working grooves of a base of brazed heat sink by forging to perpendicularly erecting heat sink fins on the heat sink base, and feeding air in a laminar flow at forcibly air cooling time. CONSTITUTION:Heat sink fins 12 are erected on a heat sink base 11 by cold forging. To this end, the width of grooves 11a of the base 11 formed by the cold forging is formed the same as the thickness 12a of the plate of the fin 2.

IPC: G01B11/24
Filed: 1986-09-26
Abstract: PURPOSE:To achieve accurate decision, by converting an output of an optical type displacement detector into a digital signal to compare a differential coefficient obtained by differentiation with a set value. CONSTITUTION:An output of an optical type displacement detector 2 which detects displacement of a side wall of a tire 1 continuously is converted into a digital signal with an A/D converter 4. This signal is connected to identification circuits 6A and 6B for unevenness which picks up unevenness with the cutback width below a set value via a differential comparator circuit 5 which classifies this signal as levels above a set positive differential coefficient value, below a set negative differential coefficient value and in an intermediate range. Moreover, a time-based coordinate of a peak part is calculated. Gate setting circuits 7A and 7B for unevenness are arranged to judge the width of the unevenness centered on the coordinate and unevenness extracting/judging circuits 8A and 8B to judge an average height of the peak part at the unevenness for one circumference of the tire 1 in comparison with an allowable value. This enables the detection of the size of unevenness with a small area, picking them up separately thereby achieving a higher accuracy of the judgement.

When a change collection switch is operated, the coins in the change collection parts 12 and 13 are dropped and discharged from a change discharge port 15, and they collide with the rotary board 21 and the transportation direction is switched. The coins descend by gravity while they slide or roll on the surface of the rotary board 21, and they are collected in the safe through the second branch pipe 23. Thus, the coins can easily be collected in the safe only by opening the door 2 and operating the change collection switch.
