Filed: 2000-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a parts feeder aligning and feeding parts to a prescribed position in a prescribed attitude, having a high feeding speed even in a feeding method using only one vibrating body, usable even for an airless system, and having a compact structure easy to manufacture at a low cost. SOLUTION: Parts are aligned and fed by the vibration of one linear feeder, and misaligned parts are collected by the power of a speed-controllable motor. A box opened at the upper section is applied with a seesaw-like motion around a rotation fulcrum position by the rotating motion of an arm fitted to the motor located apart from a fulcrum. When one side of the box is lowered near the bottom dead center by the seesaw-like motion, misaligned parts are collected in the box. When this side is lifted to the top dead center from the bottom dead center, the other side is lowered to the bottom dead center. Since a groove is provided at the position of the bottom dead center, parts are hooked on the groove.  When the side of the box is lifted near the top dead center, only the parts hooked on the groove are inserted into a parts alignment standby section near the top dead center by the inclination of the groove, and these actions are repeated.

IPC: H05B3/72
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a far-infrared ray thin heater with a small annexed space accompanying installation, and provide a substrate-heating furnace having high production efficiency. SOLUTION: Since exothermic bodies 38 are installed in a sheet metal 32 for heating a far-infrared radiating layer 44 and the exothermic bodies 38 are connected with an external power supply from an end part of the sheet metal 32, space is not needed to be installed for connecting them at a the rear face side of the heater 30. In addition, because this is constituted with the heat being generated from both sides of the heater 30 by the installation of the far-infrared radiation layers 44 at both sides of the sheet metal 32, no heat insulating space is necessary to be installed between respective stages, so as to suppress mutual interference of heat, even when it is used by being piled up in stages.  Therefore, because the size of space necessary for installing the heater 30 is almost matches with that of the sheet metal 32, the far-infrared thin heater with a small annexed space accompanying installation can be obtained.

Title: Method for obtaining free energy by using improved floating engine
Inventor: MIZUKI MIKIZO
IPC: F03B17/04
Filed: 2000-11-10
Abstract: PROBLEM TO BE SOLVED: To introduce a method for improving a recorded floating engine based on new analysis knowledge and for obtaining free energy through the operation thereof. SOLUTION: It is found that the free energy can not be obtained at all by a foaming air blowing-in method according to a detailed analysis. When a combination of simultaneous vortex generators 4 for air and water formed into a convergence type is used, a large amount of air can be delivered without producing bubbles. It has turned out to be good that a stream modifying skirt panel 6 is attached to a bucket 3 to cover the surface of an operation part with water containing bubbles in order to reduce the water-flow resistance friction of the operation part and the width to depth ratio of a box-type bucket is set around six or more, and it is shown that higher free energy can be obtained by increasing the operation speed at the same time. Those improvement methods are adapted for the floating engine.
