Title: Magnetic recording and reproducing device
Inventor: HIRAYAMA HIROMICHI
IPC: H04N5/783
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a good reproducing signal while making a magnetic tape for recording data travel in a long-time mode at an optional traveling speed by providing a double azimuth head at a position 180 deg. symmetrical to an upper drum. SOLUTION: The rotational loci of the magnetic heads of double azimuth heads DAH1 and DAH2 are arranged so as to be in parallel with the track of a magnetic tape on which data is recorded in a long-time mode while being continuously traveled at a speed different from a taped speed during recording and a reproducing operation is performed mainly by the Hep1 and Hep2 of an EP head. When the levels of reproducing signals from the EP heads Hep1 and Hep2 reach a specified level, a change is made to reproducing signals from the SP heads Hsp1 and Hsp2 from the double azimuth head. The head track width of the SP head is set so as to prevent the generation of reproducing signals from tracks alternately every other track to targeted track for reproducing.

Title: Hanger winding height indicator
Inventor: HIBINO YOUZOU
IPC: G01B11/00
Filed: 1978-03-01
Abstract: PURPOSE: To enable the indication of height, by locating a plural number of floodlights at a structure which corresponds to a hanger of a loading machine, and by allowing a crane operator to recoginize an image formation distance of a spot light from each floodlight.  
     CONSTITUTION: A bottom of a transverse trolley 3 refers to a projecting standard surface L which serves to determine a distance between a hanger and a gound surface, that is, the height from the gound surface. Floodlights 7aW7e can adjust the distances which can form in stages the respective images by selecting properly the respective types of lenses. By adjusting a lense type and an intensity of illumination, an image information of a spot light is set at such an intensity of illumination that a crane operator can recognize within the area ranging over the certain widths of from ha to he centering around an image formation position. The crane operator can determine the hanger's height corresponding to the image formation by confirming visibly the image formation of a given spot light.

Filed: 1984-02-09
Abstract: PURPOSE:To attain to miniaturize a wind sensor and to improve durability and accuracy, by detecting wind velocity and a wind direction by detecting the change in the pressure in a pressure chamber by inflow air. CONSTITUTION:Pressure holes 7a-7d are provided to the side walls 3 of pressure chambers 6a-6d formed of stainless diaphragms 4a-4b in directions crossing at right angles to each other so as to be communicated with the open air. The air stream flowed in from the direction shown by the arrow W passes slits 5 and flowed into the pressure holes 7a, 7b. The pressures in the pressure chambers 6a, 6b are raised and positive distortions corresponding to the pressures are generated in the diaphragms 4b. Because the angle theta of the wind direction W is small, the rising degree of pressure is higher in the pressure chamber 6a as compared with the pressure chamber 6b and the distortion of the diaphragm 4a is larger than that of the diaphragm 4b. The output of a strain gauge 8a is larger than that of a strain gauge 8b, and a wind direction and wind velocity are uniquely determined by comparing both outputs.
