Title: Smoke detector
Inventor: ERUBUIN TORETSUSHIYU
IPC: G01N21/53
Filed: 1980-02-19
Abstract: A smoke detector containing a radiation source operating in a pulsed mode and a scattered radiation receiver connected in a coincidence circuit. This circuit contains a counter which counts both the radiation pulses and the incoming scattered radiation pulses. With undisturbed operation this counter, following each radiation pulse, has an even numbered counter state. The appearance of an uneven numbered counter state is indicative of the presence of spurious pulses and leads to resetting of the counter to null, so that there is prevented attainment of a counter state adequate for tripping an alarm signal. On the other hand, with the presence of a predetermined even numbered counter state there is triggered an alarm. Such smoke detector is almost immune to spurious pulses and does not tend to trigger faulty alarm signals.

IPC: B60C11/24
Filed: 1979-02-19
Abstract: PURPOSE: To detect a wear step difference due to shoulder wear correctly by a method wherein a recess is formed in the roughly central portion of the shoulder rib of a tread, and the depth of the recess is so set that the recess vanishes when the wear step difference between the shoulder rib and a crown rib has just exceeded a predetermined dimension.  
     CONSTITUTION: In a tread 13 of a tire 11 having tread grooves 16, a tetragonal recessed groove 17 which vanishes when the wear step between a shoulder rib 14 and a crown rib 15 has just exceeded 2mm, for example, is formed in a multi-step configulation in the roughly central area of the rib 14 between the side wall 11a of the tire and the groove 16. The depth of the first step portion 17 is set at the value of b at the time when the wear steps a, b of the ribs 14, 15 are equal to 2mm after a progress of shoulder wear on front wheels. The depth of the second step portion 17b is set at the value of b at the time when the wear steps a, b are equal to each other after a progress of center wear on rear wheels. By this, the wear steps due to shoulder wear can be detected correctly.
