Title: Full automatic washing machine
Inventor: SHIMIZU YOSHIHIRO
IPC: D06F35/00
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the requirement of separately washing colored clothes and white clothes by providing a washing machine with an electrolytic oxidation device and a power source so that washing water is brought in contact with the anode side of the electrolytic oxidation device. SOLUTION: An electrolytic cell is constituted by sandwiching a solid polymer film 4 by an anode material 2 and a cathode material 3, and of a power source to apply DC current to an anode 2 and a cathode 3 and a power feeder to transmit electric energy to an object to be decomposed in water. The electrolytic cell 1 is set so as to be in the direction to the center of the washing tub 7 so that the anode 2 side can easily come into contact with washing water. Since a water flow is generated by agitation by a pulsator 10 when washing is started, the washing water is fed to the electrolytic cell 1. By applying a voltage in between the anode 2 and the cathode 3 by a DC power source 5 at that time, chemical substances in washing water are electrolytically oxidized.  Even when dyes are eluted from colored clothes into washing water, the dyes are decomposed and decolored by the electrolytic oxidation.

Title: Radar device
Inventor: KAKIMOTO TAKASHI
IPC: G01S13/66
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To achieve excellent target tracking performance by performing three- dimensional tracking utilizing a crest value in a radar device that utilizes the reflection wave of a transmission wave being irradiated from an antenna for detecting a target. SOLUTION: A target detector 14 detects the two-dimensional position information of a target based on a reflection wave being received by an antenna 10.

Title: Pre-polishing method for metal plate for printing plate
Inventor: KUBOTA HIROO
IPC: G03F7/09
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a pre-polishing method, by which the surface of the metal plate for a lithographic printing plate can be polished without developing polishing streaks or stepped unevenness and a uniformly roughened surface can be obtained by the following main polishing. SOLUTION: In the pre-polishing method of the metal plate 12 for a lithographic printing plate, a non-woven fabric roller 14 is divided into (n) rotors. When the critical speeds of the respective divided rotors are denoted by Wc0, Wc1, Wc2, Wc3,...Wcn (rad/s), the critical speed Wc (rad/s) of the non-woven fabric roller 14 is calculated from an equation: 1/Wc2=1/Wc02+1/Wc12+1/Wc22+1/Wc32+...+1/Wcn2. Then, the rotating speed V(RPM) of the non-woven fabric roller is denoted by V×Wc, so as to rotate the non-woven fabric roller in the range that 10.5<=X, or X<=8.5 is satisfied, resulting in allowing to surely prevent the non-woven fabric roller from whirling.  Consequently, a favorably accurate pre-polishing can be executed without occurring polishing streaks or stepwise unevenness due to run-out of the non-woven fabric roller on the surface of the metal plate for the printing plate and a uniformly roughened surface can be obtained by the following main polishing.

Title: Rolling bearing
Inventor: NASHIKI MASAYUKI
IPC: F16C19/04
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To relieve deformation force and frictional force acting on a cage, to prevent damage of the cage, and to restrain bearing temperature rise by relatively forming at least a single recessed part to a circular locus of a transfer surface of an inner race. SOLUTION: A transfer surface 5 for guiding a rolling body 4 from the inside is arranged in an inner race 1, and a transfer surface 6 for guiding the rolling body 4 from the outside is arranged in an outer race 2. Three recessed parts 7 having the depth of several μm and the length of about several mm are formed at an equal angle on the transfer surface 5 of the inner race 1. Since a preload acting on the rolling body 4 is reduced or wholly eliminated in a position corresponding to the recessed parts 7, friction of the rolling body 4 and the inner race transfer surface 5 is reduced. Since a slide to the bearing center side of the rolling body 4 is allowed before deformation of a cage 3 becomes large, excessive deformation force and frictional force do not act on the cage 3 to thereby prevent damage of the cage 3 as well as to restrain a rise in a bearing temperature.
