Abstract: PROBLEM TO BE SOLVED: To significantly reduce the incidence of a turn-up failure and the consumption of an adhesion preventing agent by providing minute irregularities on the outer face part of contact which comes into contact with at least a tire constituent member, in a bladder device for turn-up of a tire molding machine which turns up the tire constituent member around beads by inflating into the form of a doughnut. SOLUTION: Minute irregularities 5 - numerous minute projecting gatherings - which are 100-500 μm high are formed on the outer face part 4 of contact coming into contact with at least a tire constituent member, on the outer face of the bladder 3. A bead 11 is set on the end part 9a of the caulked tire constituent member 9 and the bladder 3 is inflated into a doughnutlike form using a fluid (an arrow A) to carry out a turn-up process and the end part 9a is turned up around the bead 11. In this case, the minute irregularities 5 of the bladder 3 rub against the end part 9a and this may result in the generation of rubber tailings eve at the end part 9a. However, the tailings hardly stick and accumulate in the minute recesses of the minute irregularities 5. Thus the end part 9a of the tire constituent member 9 is prevented from slipping.

Title: Pointer display type electronic timepiece
Inventor: AYUSAWA HITOMI
IPC: G04C3/00
Filed: 1984-11-19
Abstract: PURPOSE:To obtain an electronic timepiece simple and easy to use, by controlling the writing of outputs of more than two phototransistors (PTr) arranged on a dial plate into a memory circuit with a control circuit. CONSTITUTION:PTr1, 2 and 3 are arranged on a dial plate of electronic time piece to detect the positions of long and short hands. When the pointer comes over any of the PTr1, 2 and 3, light is intercepted to get the output of the PTr involved to a 'high level' which actuates a control circuit 4 to write the position thereof to a pointer position memory circuit 11. On the other hand, when the PTr1, 2 and 3 have light intercepted at the same time, the control circuit 4 is controlled by the outputs of these PTrs to check the writing of a numeral into the pointer position memory circuit 11 otherwise caused by each PTr. That is because such an interception of light is caused not by the pointer but by the condition of getting dark in the ambience. In this manner, this technique of detecting the pointer position is very simple and free of contact parts to achieve a higher durability as well as reliability and can prevent malfunctioning even when a user enters a dark place.
