Filed: 1981-12-25
Abstract: PURPOSE:To achieve a constant temperature operation of a probe stably by inserting a parallel circuit of a braking resistance and an inductance for shunt in low frequency region between a hot wire probe arranged in a fluid and a heating control circuit. CONSTITUTION:A braking resistance RDP and a shunt inductance LDP for shunt of the resistance RDP in the low frequency region are connected in parallel and inserted in series between a hot wire probe and a heating control circuit. The hot wire probe is a section represented by a resistace RW and an equivalent capacitor CWE and the heating control circuit by an equivalent inductance LA and an equivalent negative resistance -R'H, where the offset voltage is 0V. The shunt effect of the inductance LDP decreases gradually at a level above a cross frequency fDP and the impedance across the resistance RDP reaches the resistance RDP near a resoance frequency f0 by the capacitor CWE and the inductance LA. This keeps the resistance RW of the hot wire probe when heated equal to the set value R'H against those below the frequency fDP of variations in the fluid current speed containing a constant component.

IPC: G05D1/02
Filed: 1993-08-31
Abstract: PURPOSE:To increase the detecting range of a guide line by providing an image detecting means on an automated guided vehicle which automatically travels by detecting the guide line in order to detect the photographed image of the guide line in an out-focus state. CONSTITUTION:In regard of an automated guided vehicle which travels by detecting a guide line set on the surface of a traveling path, an image sensor 3 is placed against the floor surface irradiated by a projector 2. The sensor 3 includes an image sensor element 3x and a rod lens 3y which condenses the light sent from the floor surface to the element 3x. The element 3x serves as a CCD sensor to shift the normal focusing surface F of the sensor 3 from the floor surface. Therefore the waveform produced by the sensor 3 becomes gentle, and the waveform of a normal distribution shape is binarized for detection of the guide line. This processing is equal to a processing where a photographed image is filtered and smoothed. As a result, the detecting range of the guide line is increased.

Filed: 1985-09-28
Abstract: PURPOSE:To achieve increased luminous efficiency by providing a metallic reflection film having a flat surface between an index phosphor layer and color phosphor stripes. CONSTITUTION:A metallic reflection film 17 having a flat surface is provided between an index phosphor layer 16 and color phosphor stripes. When the fluo rescent screen is scanned by an electron beam from an electron gun structure 19, the index phosphor layer 16 is excited with the electron beam transmitted by the metallic reflection film 17 to emit light. But, the emitted light is shielded by a light-shielding layer 15 and only light emitted from the areas 16i of the layer 15 becomes incident upon a light-receiving plate 21 as index light through a screen panel 12 to act as phosphor stripes (I). The light emitted near the screen panel 12 becomes incident upon the light-receiving plate 21 directly through the screen panel 12. The light emitted near a front panel 11 excluding light transmitted by the metallic reflection film 17 is reflected by the film 17 and then becomes incident upon the light-receiving plate 21 efficiently through the screen panel 12.
