Title: Inline electron gun structure
Inventor: NAIKI KAZUAKI
IPC: H01J29/48
Filed: 1984-07-20
Abstract: PURPOSE:To prevent the distortion of a scanned surface formed by a central electron beam and both outer electron beams, by providing magnetic field control elements at the electron beam apertures of a disk on an electron beam emission side. CONSTITUTION:Magnetic field control elements 15-18, which are made of a magnetic substance to control leaking magnetic field from the rear portion of a deflecting yoke, are disposed at the electron beam apertures of a disk 20. The disk 20, on which the control elements 15-18 are secured, is made of an electric insulator and placed in a leaking magnetic field from the rear end of the deflecting yoke or in a magnetic field from the yoke to keep an eddy current from being caused in the surface of the disk 20 through which a horizontal deflecting magnetic field extends in the direction of an axis Y-Y. This results in preventing the generation of a magnetic flux which would hinder the change in the magnetic flux in the horizontal deflecting magnetic field. A scanned surface is thus prevented from being distorted.

Title: Valve shaft sealing device of carburetor for internal- combustion engine with supercharger
Inventor: ITOU MITSUO
IPC: F02M19/00
Filed: 1981-09-24
Abstract: PURPOSE:To perform good sealing of a valve shaft in a well slidable state with bearing  parts of a carburetor main unit supporting the valve shaft, by providing annular  grooves in the periphery of the valve shaft and supplying pressurized air in the delivery  side of a supercharger to said annular grooves. CONSTITUTION:Annular grooves 54A, 54B, at a face-to-face position to internally peripheral surfaces of bearing parts 48 in the inside of sealing members 52, are formed to  a valve shaft 46 in a carburetor main unit 42. Though a pressurized mixture in an  intake passage 44 tends to leak out to the atmosphere from between the peripheral surface of the valve shaft 46 and the internally peripheral surface of the bearing parts 48,  the annular grooves 54 are provided and pressurized air is fed from a surge tank (not  shown in the drawing), and internal pressure in the annular grooves 54 is higher than internal pressure of the intake passage 44. Accordingly, the pressurized mixture between  the valve shaft 46 and the bearing parts 48 is pressed back into the intake passage 44  never to leak out to the outside. Further the pressurized air in the annular grooves 54 flows through the sealing members 52, even if slightly leaked out to the atmosphere, a  bad influence is almost not caused, and the necessity for firmly pressing the sealing  members 52 to the valve shaft 46 is eliminated, then slide resistance can be also decreased.

Abstract: PURPOSE: To improve the efficiency of electrolytic acid washing and to make the life of anodes longer and a cost lower by subjecting a conductive material to a cathode treatment in a vessel disposed with the anodes and subjecting this material to an anode treatment in a next vessel disposed with cathodes.  
     CONSTITUTION: The conductive material 1 is continuously passed through the vessels 7, 10 filled with electrolytes 3, 5. After the material is subjected to the cathode treatment in the first vessel 7, the material is subjected to the anode treatment immediately in the next vessel 10. The anodes 4 and the cathodes 6 are respectively disposed in these vessels 7, 10. The electric circuits of the electrolytic current by a current source 8 are completed through both electrodes 4, 6, the electrolytes 3, 5, a conductor 9 and the conductive material 1. In the electrolyte acid washing method described above, the cathode treatment is executed by using the electrolyte having a low attacking property to suppress the corrosion of the anodes 4. The acid washing is then efficiently executed with the attacking electrolyte 5 by the anode treatment. As a result, the treatment time for the electrolytic acid washing is shortened and the size of a treatment plant is reduced; in addition, the longer life of the anodes is attained.

Title: Slub yarn
Inventor: SASAKI YOSHIYUKI
IPC: D01G1/08
Filed: 1980-10-30
Abstract: PURPOSE: To obtain slub yarns having a natural feeling easily, by generating a natural vibration in a filamentary tow with a flexible member in stretch-breaking the filamentary tow, and generating the unevenness in the natural vibration.  
     CONSTITUTION: A filamentary tow 1 is stretched and broken at a ratio higher than the breaking elongation between rollers 2 and 3. In the process, a running path having a guide 5 attached to a spring 4 (a flexible member) is bent in the course of the stretch-breaking zone. The repulsive force caused in the path and the elastic force provide the natural vibration in the filamentary tow to generate a great unevenness in the stretch breaking. The resultant stretch-broken fibers are then combined in a false twisting nozzle 6, etc. to wind the fibers as slub yarns having a natural feeling onto a winder 7. A coiled spring is preferred as the flexible member 4 from the standpoint of the accuracy and durability; however, a leaf spring may be used.

Title: Highly sensitive turbidimeter for measuring filtered water
Inventor: SHIMAZAKI HIROSHI
IPC: G01N21/59
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To measure the turbidity of filtered water with an accuracy of 0.1 degree. SOLUTION: A flowmeter 16 and regulating valve V1 are connected in series with a cell 11, a flow rate is made constant, and inspection water (filtered water) is allowed to flow. Laser beams from a laser beam source 12 are condensed by a lens 13 and are transmitted through the cell, and the transmitted light is received by a photodetector 14. When a turbid particle in the inspection water shields laser beams, pulses are generated in the electrical signal of the photodetector 14. The pulses are amplified by an amplification circuit 15, and a CPU 21 calculates how many times the pulses occurred per unit time and per unit flow for obtaining the number of particles and converts the number to turbidity. Transmission light is a strong laser beam where luminous flux is focused, thus reducing a cell length.  Therefore, by detecting that the turbid particle has blocked the luminous flux, the turbidity is obtained by operation, thus measuring the turbidity with an accuracy of 0.1 degree.
