Title: Recovery of contained substance from washing water
Inventor: NAKATOU HAJIME
IPC: C25C1/00
Filed: 1983-08-01
Abstract: PURPOSE:To efficiently recover the low concn. substance in washing water, by treating washing water by a medium pressure reverse osmosis membrane apparatus while treating the concentrate therefrom with a high pressure reverse osmosis membrane apparatus and applying electrolytic treatment to the concentrate to recover the contained substance. CONSTITUTION:Washing water A used in photographic treatment passes a pretreating part while the treated water is sent to a medium pressure reverse osmosis membrane apparatus 1 where receives primary separation treatment to be separated into permeated water B and a concentrate A1. The permeated water B is re-utilized as washing water or discharged while the concentrate A1 is supplied to a high pressure reverse osmosis membrane apparatus 2 where subjected to secondary separation treatment to be separated into permeated water B1 and a concentrate A2. The permeated water B1 is re-utilized as washing water or discharged while the concentrate A2 is subsequently treated with an electrolytic apparatus to recover silver. In this case, 10g/l of high purity silver is recovered from the concentrate A2. Waste water B2 from the electrolytic apparatus 3 after silver recovery is discharged after subjected to ozone treatment.

Title: Ion implanting device
Inventor: UCHIDA YOSHIO
IPC: H01L21/265
Filed: 1985-06-28
Abstract: PURPOSE:To prevent any misoperation or instability of a mass flow controller by connecting the end of a resistance wire located nearest an ion source to the ion source and earthing the other end located nearest a gass supply source. CONSTITUTION:A resistance wire to which a resistance wire 12 having a high resistance and sufficiently longer than a gas introduction tube is connected in series, is wound in a spiral form around a gas introduction tube 10 made of an insulating material and connecting an ion source 1 and a mass flow controller 9. One end of the resistance wire 12 is connected to the ion source 1 and the other end is earthed near the gas supply source. Therefore, plasma electric discharge developing in the ion source 1 is not transmitted by the introduction tube 10 and does not influence the mass flow controller 9. Consequently, there is no possibility of misoperation or instability of the mass flow controller 9 because it can be operated at the earth electric potential.

Title: Device method by synchronous ac motor
Inventor: MURATA KENICHI
IPC: B60L13/03
Filed: 1993-06-14
Abstract: PURPOSE:To provide a drive method of a moving mechanism whereby in a synchronous AC motor its maximum thrust is generated without the necessities of a pole sensor and an absolute-value encoder. CONSTITUTION:Ordinarily, a moving element 1 is moved while it is driven by an armature coil 5 of a synchronous AC motor. However, when the moving element 1 undergoes a very small displacement by its very weak driving, it has a spring characteristic whereby it is restored to its original position. Before the ordinary driving by the armature coil 5 of the synchronous AC motor, the moving element 1 is so driven by a very weak driving current that the phase theta of the driving current is changed from 0 to 2pi. Then, the phase theta whereat the maximum displacement of the moving element 1 is generated is used as an initial phase theta0 of the driving current in the case of its starting, and from this state, the drive current of the synchronous AC motor is changed.

Title: Temperature controller using superconductor
Inventor: TSUTSUI YASUMITSU
IPC: G05D23/24
Filed: 1987-06-04
Abstract: PURPOSE:To omit the feedback control and to realize the temperature control by using only a stable low voltage power supply, by controlling the energizing current of a heater via the low voltage power supply in case the resistance value of a superconductor has a sudden change by the transfer temperature of a temperature controller using the superconductor. CONSTITUTION:A constant voltage power supply 8 containing externally a resistance 6 serving as a heating element and a superconductor 7 is connected to an experiment container 4 of a temperature controller. In this case, a ceramic superconductor is used so that the transfer temperature at which the conductor 7 transfers to the superconduction from the normal conduction can be freely selected within a range between the temperature levels of liquid helium and liquid nitrogen with the temperature change of the conductor 7. In addition, the output voltage of a fixed level is always supplied to the conductor 7 via the resistance 6 regardless of the level of the current supplied from the source 8. Then the current flowing to the resistance 6 is controlled against the conductor 7 when said transfer temperature has a sudden change by the resistance value. Thus the feedback control is omitted and the temperature control is attained only by the source 8 of a simple constitution.

Abstract: PURPOSE: To exclude variation of inclination of wafers, and turn them in a constant direction, by holding semiconductor wafers with a wafer holding tool, after all the semiconductor wafers are inclined in one direction, and the inclination is arranged in the constant direction. CONSTITUTION: When air is introduced into an air cylinder, a wafer lifting tool is moved upward, passing through a window made in a mechanism base 1. The end portions of wafers engage with trenches of the lifting tool. When a cam motor 27 rotates a cam, the mechanism base 1 rotates around a fulcrum 29 as the rotation center, and inclines the whole mechanism. The wafers 4 are brought up by wafer holding tools 20, 21, and held in the trenches 26. The cam motor 27 operates again, and the mechanism base 1 is returned to a horizontal position. When air of the air cylinder is cut off, the wafer lifting tool 5 descends. The wafers are held in the air, and a cassette 3 turns to a vacant state. Thereby the wafers are arranged in a constant direction, and can be surely put in the trenches of the holding tool.

Abstract: PURPOSE: To simplify and steady the fitting of molding by a method wherein a recess is formed so as to be able to protrudingly reverse the inside of a bumper out at the molding fitting pant of the bumper and fitting leg of the molding is engaged in the recess.  
     CONSTITUTION: The recess 3 is provided at the thin wall 4 of a bumper 1. The rising section of a base part 5, the inside part 6 of the base part 5 and the central part 7 of the thin wall 4 are formed thinner than the remaining parts of the thin wall 4 so as to give hinging property.

Filed: 1993-06-15
Abstract: PURPOSE:To correct the influence of shading generating the direct irradiation field peak by comparatively processing the peak by performing the histogram calculation for each picture area of divided picture information and obtaining the direct irradiation field. CONSTITUTION:The picture data for medical diagnosis is stored in a picture memory 10 and divided right and left by a right-and-left division part 11 and inputted to a histogram calculation part 12 for each area.

Title: Electron gun frame
Inventor: IMANISHI WATARU
IPC: H01J29/48
Filed: 1979-11-05
Abstract: PURPOSE:To prevent cold emission from being discharged from a deposited material by making the aperture diameter of the second grid differ on the first and third grid sides and reducing an electric field applied to the deposited material which is made to adhere on the aperture side wall. CONSTITUTION:The hole diameter viewed from the third grid 14 side of the aperture 32 of the second grid 15 differs from that viewed from the first grid 16 side. Accordingly, when a heater is heated at a rating twice as large as in the aging process, a deposited material 30 evaporated from a cathode powder 25 adhere to only the periphery on the first grid 16 side. It does not adhere on the side surface of the aperture 32 because the side surface is concealed by the first grid 16. On the other hand, since the electric field from third grid 14 is interrupted by the aperture on the third grid side of the second grid during operation, it hardly applies to the deposited material 30. This can prevent cold emission from being discharged from the surface of the deposited material 30.
