Title: Pulsator assembly for washing machine
Inventor: KIM YONG-CHOL
IPC: D06F17/10
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a pulsator assembly for washing machine capable of preventing the entanglement and damage of laundry and improving the washing effect. SOLUTION: When this pulsator assembly 50 is rotated, a rotary stream is generated inside a washing tank 60 by a stirring blade 21. Simultaneously, washing water present in the internal space of the pulsator assembly 50 flows back to the inside of a guide groove 21a, and is led to a jetting hole 25 along the guide groove 21a and is jetted to the upper part of the jetting hole 25. As a result, a stream jetted upwards through the jetting hole 25 is formed together with the rotary stream formed by the stirring blade 21 and a turbulent flow is generated inside the washing tank 6. In the meantime, a blade 37 generates a radial stream by imparting centrifugal force to the washing water by the rotation of the pulsator assembly 50.  By the radial stream, the washing water flows into a duct 11 and foreign matters are filtered by a filtering net in the process of flowing out through a flow-out hole at the upper part of the duct 11.

Title: Scanning electron microscope
Inventor: KATAOKA HIROSHI
IPC: H01J37/147
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of a dedicated device for blanking by varying in the maximum value or more or in the minimum value or less current or voltage within a scanning period within one scanning period outside a scanning period varying current or voltage of a deflecting system in a specified rate to the time containing an effective scanning period. SOLUTION: The moving speed of electron beams moved together with an outer region than a scanning region of the electron beams in the scanning period is raised outside the scanning period, and the amount of the electron beams received by the scanning region outside the scanning period is suppressed small, and damage caused by electron beams of the scanning region can be prevented same as when blanking is conducted outside the scanning period. The electron beams strike against the outside of the scanning region outside the scanning period, but since the moving speed of the electron beams is high, the amount of electron beams per area is little, and damage of a sample is made small. If the scanning period is made short and flyback period is made long, the electron beam striking time in the scanning region per time is short, and damage of the sample is furthermore made small.

Title: Treating apparatus for nitrogen-containing waste water
Inventor: MURAKAMI YASUNOBU
IPC: C02F3/30
Filed: 1987-09-26
Abstract: PURPOSE:To make it possible to obtain good treated water, by providing a means which calculates the amount of air to be fed, from the signals for values measured by a means for measuring the amount of air fed and for values measured by a dissolved oxygen- concentration meter, such that the air exposure time in the subsequent treating step is approximately the same as a standard air-exposure time, and which controls the air-feeding means. CONSTITUTION:The amount of the air which is being fed from an air-feeding means to a means for exposure to air is measured by a means 3 for measuring the amount of the air fed. At the same time, the concentration of the oxygen dissolved in the original water in a treating tank 1 is determined by means of a dissolved oxygen-concentration meter 6. Signals for these values are inputted to a calculating and controlling means 7, which calculates the amount of air to be fed such that the air exposure time in the subsequent treating step is approximately the same as a predetermined standard air-exposure time, and which controls the air-feeding means 3 so that air is fed in an amount equal to the amount calculated. As a result, even if the quality of original water changes, properly treated water can always be obtained. This is so because one treating process is divided into a standard step of exposing to air and a step of anaerobic treatment; nitration and denitrification are allowed proceed simultaneously in the former step as in the beginning, and denitrification is allowed to efficiently proceed in the latter step.
