Title: Thin film magnetic head
Inventor: SAKATA TOSHIYA
IPC: G11B5/39
Filed: 1984-05-23
Abstract: PURPOSE:To improve the waveform of an output voltage and to detect surely the position of information by providing a magnetism-shielding material between a magnetoresistance effect element and a magnetic recording medium facing said element. CONSTITUTION:The magnetism-shielding material 14 provided between the MR element 4 and the magnetic recording medium 9 facing the element prevents the influence of the magnetic flux leaking from the medium 9 on the element 4 and is formed of a ferromagnetic material such as ferrite. The magnetic flux leaking from a magnetization transition region 10 draws a closed loop as shown by arrows in the material 14 on account of the presence of such material 14 even in the position of the region 10 past the position above a magnetic gap 3. The taking of the leaking magnetic flux into the element 4 is thus obviated. The waveform of the output voltage from the magnetoresistance effect is thereby improved and the thin film magnetic head which can detect distinctly the position of information is obtd.

Title: Reflective sheet and its manufacturing method
Inventor: MURATA KOUICHI
IPC: B29C59/04
Filed: 1978-08-26
Abstract: PURPOSE: To obtain a reflective sheet useful for a guard rail and others by feeding a sheet of colored on transparent, on fluorescent soft synthetic resin material in a heat- softened condition to the space between a roller having a smooth surface and a roller having surface with concavity and convexity form a fine convexities and concavities only in one face of the sheet.  
     CONSTITUTION: A sheet 1a of a colored transparent, fluorescent soft synthetic resin material is brawn out from a draw-out roller 3, and heated to be softened by a heater 4 and is transferred to the space between a roller 5 having a smooth outer circumference face and a roller 6 having an outer circumference face with cncavities and convexities to form a finely roughened portions 2... only on one face of the sheet 1a. The sheet 1a is cooled by a cooler 8 and thereafter is taken up by a roll 7 to a long belt-shaped reflective sheet. The reflective sheet can be certainly recognized from a remote location because the fluorescent synthetic resin can generate a fluorescent light and the light incident to the surface is freely reflected or refracted in the finely roughened portions, and the sheet can also be used for a curved member because it has a good flexibility.

Abstract: PURPOSE: To avoid the trouble some switch selection, by the sound volume of time- cast lowered or entirely eliminated at the preset time or time band, by providing the unit performing the sound volume of time-cast automatically lowering or completely erasing at an arbitrary time or timeband.  
     CONSTITUTION: The time-cast set and storage circuit 2 stores the sound volume with normal volume or reduced volume with the key switch input unit 5 in advance. The time-cst judging circuit 3 produces the signal S 5  to output normal sound volume by referencing the data of the time-cast set and storage circuit 2 through the time- cast tone triggering signal S 1  and the time data S 2 . Thus, when the enable signal S 5  is produced, that is, normal sound volume, the voltage is fed via the resistor 11, the transistor 10 is ON, and if no S 5 , that is, reduced sound volume, the transistor 10 is not ON. Accordingly, the drive voltage induced on the sound developing body 6 is reduced and the sound volume is lowered.

Title: Dynamic loud speaker
Inventor: INOUE HIDEAKI
IPC: H04R7/02
Filed: 1982-06-17
Abstract: PURPOSE:To obtain the flat frequency characteristics for a speaker containing a voice coil attached to a rectangular diaphragm with eccentricity, by varying the stiffness value at the edge part of the diaphragm. CONSTITUTION:A voice coil is attached to a rectangular diaphragm 1 with eccentricity. The stiffness value is set larger at the edge part of the diaphragm 1 further away from the voice coil than that at the edge part close to the voice coil. A hardener is impregnated to a rectangular part 11a to increase the stiffness value. As a result, the diaphragm 1 has vibrations around the outside of the total length of the diaphragm 1. This eliminates generation of an adverse phase component to obtain all in-phase outputs. Thus the flat frequency characteristics can be obtained.

Abstract: PURPOSE: To enable the accurate arrangement of ink dots by prescribing the detection zone adjacent to an aperture plate by detection light and reducing the quantity of light detected by an optical detector to detect the presence of the ink droplet of the detection zone. CONSTITUTION: An ink droplet detector is equipped with an elongated curved light assembly consisting of a plurality of curved light sources arranged in parallel and a curved light detecting prism. For example, the light from the LED 115 of the elongated curved light assembly is incident on the bottom side 128 of a curved light source prism to be reflected by the inclined surface 126 thereof and this reflected light is reflected downwardly by the inclined surface 126 of the curved light detecting prism to irradiate a photodiode 117. The presence of the ink droplet of the optical detecting zone between the curved light sources and the curved light detecting prism is detected on the basis of the reduction of the quantity of light detected by the photodiode 117.  When the offset between ink cartridges is calculated, an elongated support plate 127 is displaced forwardly and the aperture plate 125 supported on the rear is positioned on an ink droplet detector. At an unnecessary time, the aperture plate 125 is housed in a protective housing 135.
