Title: Magnetizer
Inventor: HIRASAWA MASAYUKI
IPC: H01F13/00
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of magnetic contamination chipping, etc., by providing a protection member formed of thin metal which covers an entire of an outer circumference of a magnetic yoke in a magnetizer. SOLUTION: A magnetizer, wherein a non-magnetic magnet is inserted to a magnetic yoke 10 for magnetization, is provided with a protection ring 20 which covers the entire outer circumference of the magnetic yoke 10. A ring formed of non-magnetic metal, such as titanium alloy and a ring formed of magnetic metal such as steel, can be used for the protection ring 20. Since even a ring formed of magnetic metal is sufficiently thin, magnetic flux will not escape to the thickness and vertical directions. Furthermore, since it is a magnetic body, air gap is eliminated and good magnetization efficiency is obtained. Since the protection ring 20 is provided, contamination, chipping, etc., are not generated by rubbing when it comes in contact with a magnet ring.  Since the contact surface of the protection ring 20 with an outside non- magnetic magnet ring is coated with a material of small friction coefficient or wrapped with a tape, friction becomes less and contamination is hardly generated.

Title: Structure of air-suction part for air compressor
Inventor: TAKAHASHI JIYUNJI
IPC: F04B39/16
Filed: 1980-12-25
Abstract: PURPOSE: To promote the dust-removing efficiency and the like by providing the second dust-removing chamber with air-dashing walls inside between the first dust-removing chamber with an air-filter and a compression chamber for removing minute dust passing through the air filter by the air-dashing walls and the like.  
     CONSTITUTION: When the sucked air from a suction port 11 passes through an air filter 12 in the first dust-removing chamber 6, the dust contained in the air is filtered and removed, but the air containing dust of minute particles enters into the second dust-removing chamber 7 from a connecting port 13. Although the stream of the air meanders as it passes through the second dust-removing chamber 7, particles of the dust go straight by inertia, and is consequently removed as they stick to surfaces of air-dashing walls 15a, 15b, a partition wall 16, and the like. The air whose minute dust is removed in the second dust- removing chamber 7 is sucked into a compression chamber 18 from an exhaust port 14. This construction permits to promote the dust-removing efficiency and prolong the life of an air compressor.

Title: Frequency converting circuit
Inventor: INOUE SHINICHI
IPC: H03D7/14
Filed: 1987-07-29
Abstract: PURPOSE:To cause the constitution of a circuit to be simple and small-sized by generating a signal in which a distortion compensation signal is added to a high frequency signal from the hybrid circuit of a frequency converting circuit main body. CONSTITUTION:The signal level of a generating signal, divided into two and supplied by an output hybrid circuit 39, is reduced below a prescribed level by an attenuator 38 and supplied to a diode 37, and the diode 37 is operated in a nonlinear area. When an intermediate frequency signal is frequency- converted, a distortion is generated. The high frequency signal having the distortion component is mixed with the high frequency signal obtained at the output hybrid circuit 39 by a diode 33. Thus, by a high frequency output amplifier, the distortion generated at the time of an amplification is eliminated and, as a result, the high frequency signal with few distortion can be sent.

Title: Higher harmonic factor sound source system
Inventor: KITAMURA MINEO
IPC: G10H7/00
Filed: 1988-07-29
Abstract: PURPOSE:To obtain a smooth sound change by providing the title system with an interpolating means for outputting the waveforms of respective parts of a sound signal synthesized by a higher harmonic factor synthesizing means and outputting the interpolated results of wave-forms of respective parts. CONSTITUTION:The higher harmonic factor synthesizing means 2 resynthesizes the waveforms of respective parts of a sound signal on the basis of applied higher harmonic factors. The interpolating means 8 outputs the waveforms of respective parts of the signal synthesized by the means 2 and outputs the interpolated results of the waveforms of respective parts. A higher harmonic factor extraction means 1 extracts the higher harmonic factor of the inputted sound signal and applies the extracted factor to the means 2. Since the storage and reproduction of sound waveforms is executed only on the basis of the higher harmonic factor of the sound signal, the capacity of processing data is extremely less, the feature of an original sound is not lost by the extraction and synthesis of a higher harmonic factor and the waveforms of respective parts of the sound signal can be interpolated. Consequently, a smooth sound change can be attained.

Title: Expansion type antenna reflector
Inventor: NARITA MASAO
IPC: H01Q15/20
Filed: 1985-08-29
Abstract: PURPOSE:To reduce the weight of an expansion type antenna reflector so as to make the reflector larger in size, by causing the reflector to make expanding movement and, at the same time, to obtain sufficient tension at its reflector surface after expansion by utilizing the centrifugal force of weights. CONSTITUTION:At the time of storage, holding wires 22 are wound around a rotary drum 21 and weights 20 are fixed to the periphery of the drum 21, and then, a flexible thin film 14 is folded. At the time of expansion, the rotary drum 21 is rotated by a motor 19 and the weights 20 fixed to the periphery of the drum 21 are released. Then the weights 20 receive centrifugal force and the holding wires 22 are disengaged from the drum 21. Since the rotational speed of the rotary drum 21 after expansion is set at a prescribed value so as to give prescribed centrifugal force to the weights 20, prescribed tension is given to the flexible thin film 14 and the thin film 14 can maintain the shape of a reflector. Since the energy consumption caused by the resistance of a gaseous body, etc., is very small, no large torque is required for the rotational movement and, accordingly, a small-sized light motor is sufficient for the motor 19.
