Title: Production of light-transmission glass material
Inventor: AOKI MIKIO
IPC: C03B8/00
Filed: 1987-02-06
Abstract: PURPOSE:To easily obtain a light-transmission glass material having a definite concentration gradient, by diffusion a dopant into a porous glass, developing a concentration distribution of the dopant and quenching the glass in a stage of fixing the concentration distribution. CONSTITUTION:A dopant is sufficiently diffused into a porous glass material and the dopant is eluted by immersing the glass in a solvent such as a mixture of alcohol and water to develop a concentration distribution of the dopant. The dopant concentration in the obtained glass has a gradient from the surface toward the inner part. The concentration distribution having the concentration gradient is fixed by quenching the porous glass material and the obtained material is dried and sintered to obtain the objective glass material having refractive index distribution. Since the porous glass material is quenched with liquid nitrogen or dry ice, etc., in the present process, the dopant in the porous material is precipitated at the existing place. Accordingly, the concentration distribution can be maintained in the quenched product.

Title: Radar for detecting small target
Inventor: TOKISAWA MASARU
IPC: G01S7/292
Filed: 1993-02-16
Abstract: PURPOSE:To improve the signal-clutter (S/C) ratio thereby to highly accurately detect a small target on the sea by determining the stretch width in a stretching process only by the predicted moving speed of the target. CONSTITUTION:A correcting circuit 35 has an input of a receiving signal from a transmitting/receiving device 20, detecting the moving speed of the sea surface such as the current or the like and feeding a correcting signal corresponding to the moving speed to a scanning correlation circuit 33. The circuit 33 has an input of a receiving signal which has the range width stretched by a stretching circuit 32, corrects the range by the range width corresponding to the moving amount of the sea surface by the correcting signal of the circuit 35, then correlatively processing receiving signals every scanning time. The stretch width is determined only by the predicted moving speed of the target as above. Since the error is removed by the moving speed of the sea surface such as the current or the like when the processing of correlating scannings is conducted, the stretch is reduced by the stretch corresponding to the moving speed of the sea surface. Accordingly, the S/C ratio is improved and the detecting efficiency of a small target on the sea surface is improved.

Title: X-ray tube
Inventor: UCHIUMI HIROSHI
IPC: H01J35/20
Filed: 1984-02-17
Abstract: PURPOSE:To increase the gas-absorbing ability of a nonevaporated getter by performing blackening treatment on the surface of a cathode holder and on the inner surface of a cathode cylinder which are installed surrounding a getter. CONSTITUTION:Blackening treatment such as black Cr plating is performed on the surface of a cathode holder 1 and on the inner surface of a cathode cylinder 2. As a result, heat radiated from a target 4 heated to around 1,500 deg.C is more efficiently absorbed and radiated by the holder 1 and the cylinder 2 than conventionally thereby accumulating heat in the cylinder 2. Therefore it is possible to increase the temperature of the holder 1, a nonevaporated getter 6 directly fixed to the inner surface of the cylinder 2 and a nonevaporated getter 6 placed in the cylinder 2 to 170-200 deg.C which is 40-60 deg.C higher than the conventional temperature of these members. Accordingly, the gas-absorbing ability of the nonevaporated getter can be increased, thereby extending the life of the X-ray tube under high load condition.

Respective pusher rods extending along the worm-wheel axes through the worm wheels are each formed with an external screwthread complementary to and meshing with the respective internal screwthread. The rods and housing are coupled together so as to inhibit rotation of the rods about the respective worm-wheel axes while permitting movement of the rods along the respective worm-wheel axes. The screwthreads are of such hand that rotation of the worm shaft in one direction about the main axis moves the rods along the respective worm-wheel axes in one direction while opposite worm-shaft rotation moves the pusher rods axially oppositely.

Title: Method and arrangement to characterize microsize pattern

IPC: G03F7/20
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To characterize the design of a patterned layer by applying light to an arrangement by light with a specific wavelength, providing an appropriate wavelength for measuring the design of the patterned layer, measuring a reflected light close to zero from the arrangement, and indicating it as the measurement value of a reflection factor. SOLUTION: A patterned material such as a patterned film 2 is subjected to light 9 with a proper wavelength. Especially, the incident light 9 contains a wavelength in a range where the patterned film 2 absorbs more light as compared with a substrate 7 and the substrate 7 reflects more light as compared with the patterned film 2. Furthermore, the wavelength resolves the micro-size design of a pattern, for example, with a line width of W. The intensity of reflected light 11 close to zero from the patterned film 2 and the substrate 7 is measured and a reflection spectrum indicates the intensity of the reflected light 11 by a function of the wavelength of the reflected light 11.
