Inventor: MIYAMOTO TETSUO
IPC: G01W1/10
Filed: 1994-07-29
Abstract: PURPOSE:To obtain a method by which whether the weather is sunny, cloudy or rainy is judged accurately and automatically. CONSTITUTION:The sunshine is made incident on an optical-axis sensor 7. When an optical axis can be detected by the optical-axis sensor 7, the weather is judged to be sunny. In addition, when the optical axis cannot be detected, the weather is judged to be cloudy or rainy. Alternatively, an optical-axis sensor is constituted in such a way that a plurality of detection regions 4a to 4d composed of optical sensors installed at the bottom part of the optical-axis sensor 7 are irradiated with incident light so as to decide an optical-axis. When the optical-axis sensor is used and the difference in an output value between the respective detection regions 4a to 4d is within a prescribed range or within a prescribed ratio, the weather is judged to be cloudy or rainy. In addition, when the difference in the output value is outside the prescribed range or outside the prescribed ratio, the weather is judged to be sunny. In this case, as a condition under which the weather is judged to be sunny, it is desirable to add a condition under which the output value of every output region is at a prescribed level or higher. In addition, the weather may be judged in such a way that the sum of output values of adjacent detection regions is taken into consideration.

Title: Polishing sheet
Inventor: TSUTSUMI KATSUJI
IPC: B24D11/00
Filed: 1987-07-17
Abstract: PURPOSE:To let friction heat be diffused with ease at the time of polishing as well as to restrain the occurrence of clogging by providing numbers of holes passing through the front and back sides of a base material approximately in a plate form having abrasive grains at specified sections. CONSTITUTION:The surface to be ground and polished by the front side of a base material 1 approximately in a plate form having abrasive grains 6 at specified sections is opened to an external space in the back side of the base material 1 through numbers of holes 2. This constitution thereby enables both friction heat and dusts produced between the surface to be processed and a polishing sheet to be diffused to an external space. Consequently, the effect of heat against the surface to be processed at the time of polishing is reduced, thereby enabling the occurrence of clogging in the polishing sheet caused by dusts to be restrained.
