Title: Method and apparatus for warming up bathroom floor
Inventor: NAITO SUSUMU
IPC: F24D15/00
Filed: 1990-03-26
Abstract: PURPOSE:To dispense with work to build a heating layer on the bathroom floor by supplying hot water through a hot-water filling circuit to the bathtub in more volume that its capacity, thus overflowing the tub with hot water to warm up the bathroom floor, thereby warming up the bathroom floor. CONSTITUTION:An opening and shutting valve 33 is inserted into a hot-water filling circuit 12 and the opening and shutting valve 33 is controlled by a control device C inside a hot-water apparatus A. Hot water is filled into a bathtub 1 from the hot-water apparatus through the hot-water filling circuit 12, and when a volume supplied exceeds the capacity of the bathtub 1, hot water inside the bathtub 1 overflows from the brim of the bathtub down to the bathroom floor. The hot water brimming over from the bathtub 1 overflows from the entire brim to the bathtub floor and warms up the bathtub floor over a wide range. When the bathtub floor is warmed up to some degree, hot-water filling via the hot-water filling circuit 12 is stopped. Since the bathroom floor is warmed up with hot water overflow of the bathtub 1, discomfort in bath taking is removed. Moreover, inasmuch as this warming-up device dispenses with special piping, the bath apparatus equipped with the bathroom floor warming-up device can be of simplified construction.

Title: Horizontal band saw machine
Inventor: TAGUCHI MASAYUKI
IPC: B23Q15/12
Filed: 1983-05-06
Abstract: PURPOSE:To automatically and surely obtain the most suitable speed of swaing, by classifying the quality of a material to be cut off and manually setting a speed of sawing, performed by a stepless speed change gear, to be checked through a closed loop system so as to start the actual sawing after completion of setting the speed of sawing. CONSTITUTION:When a material to be cut off is sawn at a speed of sawing corresponding to its quality of being cut, if one of the switches 103A-103D selecting a speed of sawing is pressed, a corresponding voltage signal, being output through the corresponding constant voltage means 105A-105D, controls an electric motor 95 through an electric motor control circuit 109, changing the position of a movable cone 49m in a stepless speed change driving sprocket 49, thus the speed of sawing is adjusted. Detecting this position of the cone by a detecting means 97 to be compared with a preset voltage signal by a comparator 107, said position is controlled by the control circuit 109 so that the compared deviation of zero may be obtained. Then if the deviation becomes zero, a start signal of sawing is output to a sawing control means 111. In such way, the speed of sawing, being automatically further surely obtained, enables the material to be efficiently cut off without causing any decrease of a saw tooth life.
