Title: Harmonic mixer
Inventor: KANEKO TOMOYA
IPC: H03D7/14
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To obtain a harmonic mixer, which makes an input circuit of a local signal a simple configuration to make a panel configuration simple and is capable of being manufactured at low cost by outputting a radio signal from an unbalanced terminals of a balun and supplying an intermediate frequency signal through a high impedance line in accordance with its line. SOLUTION: An Lo signal, inputted from a balanced terminal 17 of a balun 10, makes one side diode 18a conductive in a positive half cycle and makes the other diode 18b conductive in a negative half cycle. Thus, a full-wave rectified waveform is outputted about the Lo signal at an unbalanced terminal 14. An output waveform to the terminal 14 is an even function circuit which performs an output having the same polarity in two half cycles to a sine wave input, having positive and negative bipolarity amplitudes from a balanced terminal. Thus, it does not have to make the frequency of a local frequency signal higher as the frequency of a high frequency signal to be outputted becomes high. Thus, the requirement, it does of a local oscillator of high frequency is eliminated.

Title: Production of magnetic disk
Inventor: TAKAHASHI JUN
IPC: G11B5/70
Filed: 1984-12-28
Abstract: PURPOSE:To improve its reproduction output without decreasing the strength of the coated film and without deteriorating the recording density by mixing isotropic magnetic powder into Ba-ferrite powder in a paint for forming the coated film. CONSTITUTION:Isotropic magnetic powder is mixed into barium-ferrite powder in a paint for forming a coated film in the production of a magnetic film having a barium-ferrite vertical magnetic coated film. Less than 40% (weight), especially 30-40%, Ba-ferrite magnetic powder in the paint is preferably replaced by the isotropic magnetic powder. Consequently, sigmas of the whole magnetic powder is increased. The Ba-ferrite magnetic powder may be treated with a dispersant. Since the packing density of the isotropic magnetic powder is fairly high and the isotropic magnetic powder has an isotropic characteristic notwithstanding the orienting method, the powder can be used jointly with the Ba-ferrite powder without any hindrance. Consequently, the degree of orientation is not decreased, a decrease in the recording density is not brought about, and the reproduction output can be increased without increasing the content of the magnetic powder in the coated film excessively.

Title: Bottom structure of small ship
Inventor: KANEKO YOSHIYUKI
IPC: B63B1/20
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide the bottom structure of a small ship capable of suppressing a power loss due to a frictional resistance between bottom plate members and water. SOLUTION: A small planing boat (small ship) is formed by disposing a propeller at the rear laterally center position of a body 2 and installing a pair of right and left step plates (plate members) 16 on the bottom at the right and left sides of the propeller. A space S is formed between the front end face of each of the step plates 16 and the body 2 (hull 2a), and the space S is opened to the side of the body 2. Because the space S formed between the front end face of each of the step plates 16 and the body 2 is opened to the side of the body 2, air in the atmosphere is sucked into the space S of the body 2 by a negative pressure generated in the space S by water flowing through the bottom, and the air flows from the space S rearward along the bottom surface of the step plates 16 so as to eliminate the water.  As a result, a contact between the step plates 16 and water is suppressed by air, and a power loss due to a frictional resistance between the step plates 16 and water is suppressed.
