Title: Magnetic material of oxide
Inventor: SHINOHARA HAJIME
IPC: C04B35/40
Filed: 1980-08-29
Abstract: PURPOSE: To lessen the temperature coefficient of saturation magnetization, by making a temperature exhibiting the maximum saturation magnetization between the compensation point of magnetization and the Curie temperature of a magnetic material of oxide having a composition shown by a specific composition formula be in a specific range.  
     CONSTITUTION: A magnetic material of oxide has a composition shown by the formula, and x, y, and z are in the range shown by the following relationships: 0<x≤ 0.7, 0.05≤y≤0.25, 0.35≤z≤2, with the proviso that 127≤105x-220y+120z≤187. A temperature exhibiting the maximum saturation magnetization between the compensation point of magnetization and the Curie temperature is in a range from -20W35°C. The reason why y, the amount of In, is limited to the above-mentioned value is that in case that y is ≤0.05, the half value width of ferromagnetic reasonance absorption is increased abruptly, and in case that y is ≥0.25, the temperature coefficient of the saturation magnetization is increased abruptly, and in case that x, the amount of V, is ≥0.7, sintering is not carried out easily. When the ranges of y, the amount of In, and x, the amount of V are obtained, consequently, the range of z, the amount of G, is given automatically.

IPC: H01J9/20
Filed: 1982-07-09
Abstract: PURPOSE:To offer a formation process for the external conductive film of a chathode-ray tube which is suitable for mass production, by forming a graphite layer by means of a printing process on an adhesive film which contracts when hardened, then by sticking the graphite layer cut and formed in desired shape to the desired position of the external surface of the cathode-ray tube. CONSTITUTION:A graphite layer is formed by means of a printing process, for instance, on a polyvinyl acetate film whose material is selected from adhesives which contract when hardened; thereafter, the graphite layer of desired shape which is made, for instance, by punching it with a press is heated in the state in contact with the desired external position of a cathode-ray tube 1. After that, said layer is returned back to an ordinary temperature and a conductive film 2 composed of said graphite layer is stuck thereon. The graphite layer having a constant thickness and shape can be easily formed on the film by means of the printing process. When the film contracts during hardening process, said graphite film which was a plane at first is tightly stuck onto the usually curved external surface of the cathode-ray tube without generating creases nor wrinkles.

Title: Method for vulcanizing tire
Inventor: KAWASHIMA KIYOO
IPC: B29K21/00
Filed: 1991-05-23
Abstract: PURPOSE:To enhance productivity of vulcanization of a tire by using both a heating medium such as steam and a pressurizing medium such as gaseous nitrogen. CONSTITUTION:A heating medium Wa at prescribed pressure is supplied into a vulcanization chamber of a tire for a prescribed time by a timer. Thereafter while orifices 7a, 7b are changed over and controlled by the timer in accordance with size of the tire and vulcanization time, the flow rate of a pressurizing medium Wb is increased so that the internal pressure is gradually raised. While the vulcanization chamber is controlled at the aimed internal pressure, vulcanization is performed. Further the internal pressure of the vulcanization chamber of the tire is detected by an internal pressure detector. While the detected internal pressure is calculated and controlled by a computer, the flow rate is increased by a power valve. While controlling the vulcanization chamber at the aimed internal pressure, vulcanization is performed. A vulcanization state is uniformed and quality is enhanced by performing agitation of both the heating medium Wa and the heating medium Wb for a long time.

Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device which is able to have white light irradiated to documents without color unevenness when reading the documents by use of a color scanner, etc. SOLUTION: The light reception period signal of a document-reading light sensor is received by an inverting circuit 14 to drive an inverter controlling IC 13. The inverter controlling IC 13 outputs pulse signals of predetermined repeating periods by the use of a drive period synchronized with the period of the light reception and thus drives a switching element 12. Therefore, a voltage having repeating waveforms is produced on the secondary side of a transformer 11 to turn on a fluorescent lamp 1.  Thus, the fluorescent lamp 1 is turned on in the drive period which is synchronized with the period of the light reception of the light sensor, and the rising of the voltage having the repeating waveforms is determined in accordance with the drive period, to make it possible to hold constant the cumulative amount of light of each color in each period of the light reception and to eliminate color unevenness.

Abstract: PURPOSE:To flatten the surface of a growth layer to be grown on a second buffer layer by growing the second buffer layer on a first buffet layer at an intermediate temperature between a growth temperature of the first buffer layer and an ordinary growth temperature of a compound semiconductor layer. CONSTITUTION:When a two-stage growth operation is executed, an Si substrate 10 is heat-treated; after that, a first buffer layer 12 of a compound semiconductor is grown on this substrate at a first temperature which is sufficiently lower than this heat-treatment temperature. In succession, a growth operation of this first buffer layer 12 is stopped once; a second buffer layer 16 is grown at an intermediate second temperature of a halfway value to raise a temperature to an ordinary growth temperature of this compound semiconductor. In succession, a growth operation of this second buffer layer 16 is stopped once; a temperature is raised to an ordinary growth temperature of this compound semiconductor; a compound semiconductor layer is grown on the second buffer layer 16 at this temperature. By this setup, even when a film thickness of the first buffer layer 12 is irregular, the surface of the compound semiconductor layer to be grown after that at the ordinary growth temperature becomes a good specular or a face close to this state.
