A pair of heating elements, through each of which an electric current flows, are formed on the film at an upstream side and a downstream side of the flow of the fluid. A constant temperature-distribution arrangement is made in which the temperature distribution in each heating element when the electric current flows therethrough is constant along a longitudinal direction perpendicular to a direction in which the fluid flows.

Abstract: Writing boards such as electric blackboards which can erase all information written thereon without wiping the board by hand. On a front surface of an endless recording medium provided in the electric black board letters, characters, etc. are written with a writing tool. The writing tool uses an ink which is easily erasable with a cleaning liquid stored in a container. At the back surface of the recording medium, there is provided a cleaning instrument which faces the back surface of the recording medium. When all the writing is to be erased, an erasing switch is pushed. A pump is operated to move the recording medium, relative to the cleaning instrument. Thus, the cleaning liquid stored in the container circulates through tubes and the cleaning instrument and squeezes the cleaning liquid through an opening of the cleaning instrument to the recording medium.

Abstract: A flow sensor includes a first heating portion, provided at a first position in a flow of a fluid, which heats the fluid and outputs a voltage in response to a temperature of the first position. A second heating portion, provided at a second, downstream position in the flow of the fluid, heats the fluid and outputs a voltage in response to a temperature of the second position, the first position and the second position being spaced from each other in a direction parallel to the flow of the fluid. An intermediate heater, provided between the first heating portion and the second heating portion, heats the fluid at an intermediate position between the first position and the second position.

Abstract: A paper feed device is mounted to a shredder. The intermittent activation time of paper feeding is adjusted, taking into consideration of the distance from the paper feed start position to the paper shredding position of a cutter of the shredder, thereby decreasing the speed of travel from the time the paper sensor detects the leading edge of the paper to the time the paper reaches the paper shredding position, so that operation is switched from intermittent to continuous activation preferably immediately before the leading edge of the paper reaches the cutter. Thus paper feed troubles associated with conventional devices are prevented, due to paper jamming, etc., caused by bending of the paper, etc.

A supporting portion is formed on the substrate for supporting the first and second temperature detecting portions thereon. The supporting portion does not have a side surface facing substantially in the direction of flow of the fluid. A side surface of the supporting portion is protected by a guard portion formed along the side surface.
