Title: Method and device for ionic nitridation of aluminum or aluminum alloy
Inventor: SUZUKI TAKATOSHI
IPC: C01B21/072
Filed: 1982-06-04
Abstract: PURPOSE:To form a nitride film having homogeneous quality and durability inexpensively with a simple device, by disposing a metal having a high affinity for oxygen near a material to be treated of Al (alloy) and nitriding ionically the material to be treated. CONSTITUTION:A base 2 which serves cathode in a hermetic vessel 1 is formed of an oxygen getter metal or the oxygen getter metal is placed so as to exist near the base 2. A material 5 to be treated which is an Al or Al alloy member is disposed on the base 2. While the inside of the vessel 1 is evacuated with a vacuum pump 3, the inside is heated with a preheater 12, and the inside of the vessel 1 is substituted a number of times with the gaseous hydrogen from a gas introducing pipe 14 to reduce the residual gaseous oxygen as far as possible. Glow discharge is generated with the vessel 1 itself or between an anode plate 13 and the cathode, and when the material to be treated is heated by the discharge, the gaseous hydrogen is changed over with gaseous nitrogen and the material is subjected to an ionic nitriding treatment.

Title: Optical pickup
Inventor: CHIKUMA KIYOBUMI
IPC: G11B7/135
Filed: 1987-04-20
Abstract: PURPOSE:To read a disk having high recording density by providing an optical wavelength transducer between a light source and a polarized beam splitter so that a light beam having a circular intensity distribution is made incident on an objective optical system. CONSTITUTION:The light beam radiated from a laser light source 1 is condensed again by a coupling length 11 and made incident on a core part of a fiber type optical wavelength transducer 12. This transducer 12 serves as an optical waveguide which is filled with a material having the large nonlinear optical effect at its core part in a desirable crystal state and transforms an incident light beam having wavelength lambda0 into a light beam including a long wavelength component having said wavelength lambda0 and a short wavelength component having wavelength lambda1(=1/2.lambda0). The light beam transformed into two wavelength components by the transducer 12 is changed into parallel beams by a collimator lens 2 and made incident on a polarized beam splitter 3. As a result, the light intensity is increased at the part near the outer circumference of an incident iris of an objective optical system. Then the information reading characteristics can be improved at a high space frequency area.

Abstract: PURPOSE:To reduce the mosaic flickering of a magnified image for an image processor which obtains the magnified pictures on a display screen by providing a noise generating means to superpose a white noise on the output of a magnifying process means. CONSTITUTION:When the addresses A0, A1... An of a horizontal/vertical address generating circuit 20a contained in a controller 20 are applied to a Y field memory 3, an I field memory 14, and a Q field memory 17 for luminance signal Y and chroma signals I and Q respectively, the same address is read twice if those addresses of the circuit 20a are shifted every bit to the lower rank side. As a result, a picture element 21 of the input side is quadrupled at the output side in both horizontal (H) and vertical (V) directions. The magnification data 3a read out of the memory 3 is supplied to an addition circuit 22. A white noise is supplied to the circuit 22 from a white noise generating circuit 11 via a level converter 12. Thus the noise component contained in the data 3a is reduced by the white noise.

IPC: H03F3/181
Filed: 1994-04-11
Abstract: PURPOSE:To improve the response of a low-frequency in an amplifier for which a chalk coil and an output transformer are used. CONSTITUTION:A chalk coil L 2 has the same windings L 2a and L 2b. The coil is connected with the plate of a vacuum tube V 1 from a power source 1 via the winding L 2a.
