Title: Rare earth magnet separator and coolant purifying system
Inventor: HIROTA ATSUSHI
IPC: B23Q11/10
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To secure a high catching rate in a rare earth magnet separator. SOLUTION: In this rare earth magnet separator 2 in which a flow passage 27 of a prescribed pad δ is partially formed around a magnet drum 23 subjected to rotary driving in a tank 4 and magnetic particles contained in a coolant flowing through the flow passage 27 are adsorbed by the magnet drum 23 to remove them, the diameter D and the width of the magnet drum 23 are set at 250 mm or more and 820 mm or more, respectively, and also the gap δ of the flow passage 27 is set at 5-6 mm.  In the rare earth magnet separator 3, since the larger the diameter D of the magnet drum 23 is, the more the wetted area is increased, a catching rate is heightened, and when the width of the magnet drum 23 is increased, the flow velocity of the coolant is lowered to increase the catching rate, and since attracting force of a magnetic body by the magnet is increased in inverse proportion to the square of the distance, the smaller the gap of the flow passage is, the higher the catching rate obtained is. In consideration of these, items of the magnet drum 23 are set at the numeral values as mentioned above, and a high catching rate can be secured for the rare earth magnet separator.

Title: Floating type magnetic head
Inventor: KUWAMOTO YOSHINOBU
IPC: G11B21/21
Filed: 1992-04-09
Abstract: PURPOSE:To prevent the C-shaped core of the magnetic head slider of the floating type magnetic head joined to a gimbal from projecting from a floating surface. CONSTITUTION:A viscoelastic material having <=1000 viscosity (cp) and <=200 elastic modulus (kg/cm<2>) is used for a joining layer 17 for joining a magnetic head joining part of the gimbal 6 and the magnetic head slider 5. Then, the viscoelastic material is low in viscosity and is, therefore, good in penetratability. The thickness of the joining layer 17 is thus reduced. In addition, the elastic modulus itself is small and, therefore, the strain of the C-shaped core by the expansion and shrinkage of the joining layer 17 is prevented by the combined effects of both. The projection of the C-shaped core from the floating surface of the magnetic head slider is consequently obviated and the possibility that a magnetic recording medium is damaged is eliminated. Since the magnetic gap of the floating type magnetic head is not damaged, the deterioration in electromagnetic conversion characteristics is prevented.

Title: Soundproof material
Inventor: MAEJIMA SUMIO
IPC: E04B1/86
Filed: 1995-03-23
Abstract: PURPOSE: To obtain a soundproof material which is capable of effectively preventing large noise and has excellent handling quality by forming the material of a multilayered structure formed by successively laminating at least three layers; a layer of an org. high molecular polymer, a layer of non-woven fibers and a layer of knitted or woven fabrics, which are respectively specific. CONSTITUTION: This soundproof material is formed by laminating the three layers; the layer (a) consisting of the org. high molecular polymer compsn. contg. the inorg. matter, the layer (b) consisting of the org. high molecular polymer foam and/or non- woven fibers and the layer (c) consisting of the knitted or woven fabrics of large-denier yarn in order of a/b/c. The layer (a) consisting of the org. high molecular polymer compsn. contg. the inorg. matter functions as a sound shielding layer, the layer (b) consisting of the org. high molecular polymer foam and/or non-woven fibers functions as a sound absorbing layer and the layer (c) consisting of the knitted and woven fabrics of large-denier yarn functions as a sound diffusion layer. The sounds from a sound generating source are diffused by the large-denier yarn, by which the penetration of the sounds to the layer (b) is diffused.  The sound absorbing and shielding effects of the layer (b) and the layer (a) are thus enhanced and the leakage of the sounds outside is lessened.

Abstract: PURPOSE:To improve inspection accuracy of defects of a bottle mouthpiece by enlarging an S/N, by providing light sources at the right and left sides of a bottle mouthpiece to be inspected and making a reflected light on the mouthpiece surface incident to a one dimensional scanning camera through a polarizing filter. CONSTITUTION:A ray emitted from a light source 2a irradiates a bottle mouthpiece 3 through a diffusing plate 5a of a light source box 4a. A part of a ray 6a of the irradiated ray is reflected on the upper surface adjacent to the light source 2a of the mouthpiece 3 and enters a one-dimensional scanning camera 8 through a polarizing filter 7. While, other part of a ray 9a transmits a side wall of the mouthpiece and is reflected on the upper surface of the mouthpiece away from the light source 2a, but it is absorbed by the filter 7 and is not made incident to the camera 8. As in the same case, the reflected light from the mouthpiece by the irradiated light of a light source 2b is also made incident to the camera 8. A light emitting pattern of the mouthpiece 3 by the reflected ray is compared with a standard pattern and the quality of the bottle mouthpiece is inspected.

Title: Tone signal modulation compensating circuit
Inventor: SHIMIZU SATOSHI
IPC: H04B1/40
Filed: 1990-04-05
Abstract: PURPOSE:To easily obtain a radio equipment with the constant degree of tone modulation regardless of a tone frequency by canceling the modulation frequency characteristic of a modulator by passing the tone signal through a low-pass filter provided between the encoder for tone signal generation of a tone scale and a mixer to mix a sound signal and the tone signal. CONSTITUTION:The output of a microphone 1 is impressed to an amplifier 2 and the output is impressed through a band pass filter 3 of a sound band to a mixer 4. The output of an encoder 5 to generate the tone signal is impressed through a low-pass filter 7 to the mixer 4 and the tone signal is superimposed to the sound signal and outputted to a modulator 6. Therefore, the modulation frequency characteristic of the modulator 6 is canceled by the low-pass filter 7 to be provided between the encoder 5 and the mixer 4 to mix the sound signal and the tone signal. Thus, it is not necessary to extend the modulation characteristic of a PLL synthesizer VCO direct modulation system to a bottom tone signal frequency (67.0Hz), time for channel lock is shortened and the degree of modulation is fixed regardless of the tone signal frequency.
