Title: Plasma x-ray generator
Inventor: KATO YASUO
IPC: H05H1/24
Filed: 1984-11-09
Abstract: PURPOSE:To reduce the variation in the location of a spot radiating X-rays by removing the disturbance of the electric and the magnetic fields by installing a conductive shield having a spherical inner surface around the space including the ends of the coaxial electrodes of a plasma X-ray source. CONSTITUTION:A cylindrical electrode 1 acting as the anode and a cylindrical electrode 2 acting as the cathode are coaxially installed in a discharge case 4 charged with a gas such as neon. And, a spherical metallic shield 7 having the same electric potential as the cylindrical electrode 2 is installed surrounding a space 8 around the end of the cylindrical electrode 1 in such a manner as to make the center of the shield 7 coincide with the end of the cylindrical electrode 1, thereby assembling a plasma focus discharge tube. A high-voltage pulse from a capacitor 5 is applied across the electrodes 1 and 2 to produce plasma thereby radiating soft X-rays. Accordingly, it is possible to prevent any disturbance of the electric and the magnetic fields in the space for pinching the plasma, thereby stabilizing the location of the spot.

Title: Developing device for copying machine
Inventor: KATO KEIJI
IPC: G03G15/01
Filed: 1986-10-01
Abstract: PURPOSE:To prevent toner from scattering at the time of switching by composing a development switching device of a guide which moves and guides a 1st developing tank and a 2nd developing tank between a development position and a nondevelopment position, a magnetic force device for moving both developing tanks to the nondevelopment position, and a driving device. CONSTITUTION:When a black copy is taken by the 1st developing tank 2 first in two-color print copying operation, an arcuate part M1 at the end part on a reverse paper feed side D1 abuts on the plate surface of a screen 14 and an arcuate part M2 on the end part of the reverse paper feed side D1 of the 2nd developing tank 3 is attracted by a 4th magnet M4 to project from a 2nd entrance/exit hole 21b to the reverse paper feed side D1. When a black copy is taken again, a rack 18 is rotated counterclockwise to move up the screen 14 and then the arcuate part of the 1st developing tank 2 abuts on the plate surface of the screen 14 to position the 1st developing tank 2 at the development position A and the arcuate part of the 2nd developing tank 3 at the nondevelopment position B by entering the 2nd entrance/exit hole 21b. Thus, when toner in use is switched, neither of magnet rollers 2b and 3b rotate. Consequently, toner is prevented from scattering over a photosensitive body and the positions of the developing tanks are securely switched.

Abstract: PURPOSE:To prevent an increase in size by reducing column lines by supplying a large current to a cell at the time of reading, implanting electrons in a floating gate, averaging a threshold voltage, an electron emission, and separating a latch circuit from a cell array in a nonvolatile semiconductor memory. CONSTITUTION:The nonvolatile semiconductor memory comprises cell blocks connected in series with FGFETs to store '0' or '1' in an FG electron state, and block selecting FFTs connected in series with one-side ends of the blocks. A bit check FET is connected in series in the block to decide a logical state of the cell in a cell block bundle. A negative threshold voltage is allocated to the more cells of the bundle to store the '0' and '1'. One column line is commonly used for two adjacent memory cell bundles. A voltage to the FG is sequentially raised, implantation of electrons is stopped at a predetermined quantity of the electrons to be implanted, electrons are emitted, then the electrons are implanted, and one of pieces of binary information is stored. On the other hand, in order to prevent an increase in a chip size, a latch circuit is formed at a position separate from a cell array.

Abstract: PROBLEM TO BE SOLVED: To make it possible to form optical waveguides at a low cost by adding a transition metal oxide to a raw material constituting core parts and periodically changing the charges of the transition metal by irradiation with electron beams, thereby forming gratings which are periodically changed in the refractive index of the core parts.

The core layer 13 is then subjected to photolithography and reactive ion etching to form the core part 14 and thereafter an upper clad layer 15 having the refractive index equal to the refractive index of the clad layer 12 is formed by a flame deposition method on the core part 14. Next, the core part 14 is irradiated with the electron beam 51 at, for example, acceleration voltage 30 kv by using a scanning coil 52, by which the gratings 18 of 2×10<-4> mm in refractive index change width and 5 mm in period are formed and the plane optical waveguide 19 is formed.

Title: Manufacture of semiconductor light emitting device
Inventor: YAGI TETSUYA
IPC: H01S5/00
Filed: 1986-10-02
Abstract: PURPOSE:To simultaneously form an inner stripe upon growth of a block layer by introducing a molecular beam from an oblique predetermined direction on a substrate having a step to form a stripe hole to form a block layer. CONSTITUTION:A step 1a is formed on a substrate 1, and a block layer 2 is grown by a molecular beam 8 incident only from an oblique predetermined direction. In this case, no epitaxal growth occurs where the beam 8 is blocked by the step 1a. That is, as the layer 2 is grown in the bottom of the step 1a, a stripelike hole 1a is formed to the sidewall of the step 1a. Then, a lower clad layer 3, the active layer, an upper clad layer and a contact layer are sequentially grown while irradiating the beam 8 from the whole peripheral direction on the substrate 1. Thus, an inner stripe can be formed simultaneously upon growth of the block layer.

IPC: B60C25/14
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To enable carrying out works simply, rapidly and surely without skill especially in case of installing a flat tire, by installing non-rotational pressure body having a rust joint portion that mounts a tire on a wheel and by dropping a bead portion into a drop center. SOLUTION: In the initial condition of fitting work of an upper bead part 20a of tire 2, guiding projection portion 23 of non-rotational body 6 is applied to a rim end of upper side circumference 1a of wheel 1, and the upper bead part 20a of tire 2 or its vicinity is pressurized at a rust joint portion 7. At this time, the upper bead part 20a that is to be fitted is in the position separated from wheel 1, but it can be pressurized by an auxiliary rust joint portion 7b of rust joint portion 7. Further, because a radius of curvature of lower circular arc has been formed to become larger, a contact area with the upper bead part 20a becomes larger, and the upper bead part 20a is easy to be entangled, thus the upper bead part 20a can be guided to drop into a drop center 17 side still more surely.
