Title: Production of substrate for microwave circuit
Inventor: ISHIKAWA KATSUHISA
IPC: H05K1/02
Filed: 1983-04-20
Abstract: PURPOSE:To form a substrate for a microwave circuit constituting a non-reversible circuit element by adhering an alumina substrate with lithium ferrite while heating them in vacuum to remove bubbles and pinholes. CONSTITUTION:Lithium ferrite 4 is embedded in the hole 2 of the alumina substrate 1, glass paste 3 is sucked from one side of the substrate 1 and dried and the glass paste 3 is applied to the other side and dried. Subsequently, the alumina substrate 1 and the lithium ferrite 4 are adhered with each other and printed. Namely, the alumina substrate 1 and the lithium ferrite 4 are heated from room temperature to about 750 deg.C at the rate of 400 deg.C/hr and held for 10min while being kept at <=10<-2>mm.Hg vacuum until the end of the holding time. The bubble removing effect is not sufficient under the condition >=10<-2>mm.Hg. Thus, <=10<-2>mm.Hg vacuum makes it possible to discharge air or remaining organic gas adsorbed in glass powder easily and remove bubbles.

Title: Magnetic recording medium
Inventor: USHIGOME HISASHI
IPC: C09D201/00
Filed: 1993-03-29
Abstract: PURPOSE:To improve durability and weathering performance in a high temperature/high moisture atmosphere of a magnetic recording medium by a method wherein a magnetic paint is applied on a non-magnetic support layer to form a magnetic layer and peptone acid Na is contained in the magnetic layer. CONSTITUTION:In this magnetic recording medium, a material as moisture and heat absorbing agent such as peptone acid NA is added to a magnetic material and a magnetic paint thus obtained is applied on a non-magnetic support body to be contained into a magnetic layer. The peptone acid Na as additive is a straight chain saturated fatty acid salt having 7 carbon atoms in the base skeleton of the molecule while it has six hydroxide groups per molecule. Hence, the substance absorbs moisture in the atmosphere and further causesan endothermic reaction in a moisure absorbing process. This enables the suppression of substantial degrading attributed to a high temperature and high moisture atmosphere of the magnetic layer of the magnetic recording medium even under an endurance test in the high temperature and high moisture atmosphere and even under a weathering test in a severer atmosphere thereby eventually improving the durability and weathering performance of the magnetic recording medium.

Title: Reduction projection type exposure device
Inventor: HAYASHI YUJI
IPC: G03F7/20
Filed: 1987-03-24
Abstract: PURPOSE:To correct the dispersion in illumination intensity without replacing a condenser lens with new one by a method wherein the title device is provided with the condenser lens for exposure made of spherically curved transparent elastomer to make the curvature radius of lens changeable by the elastic deformation of raw material. CONSTITUTION:A condenser lens 1 made of elasticity-deforming transparent raw material is composed to make the lens curvature changeable by providing raw material with convex surface for fixing curvature changing arms 5 extending in the radial direction on the peripheral edge of the condenser lens 1. When the fine pattern on a reticle 2 is exposed to a semiconductor substrate 4 through a reduction projection lens 3, if the peripheral part exposing pattern becomes larger than the central exposing pattern, the curvature radius of condenser lens 1 can be changed to equalize the pattern diameter of overall exposure region by means of controlling the inclination of illumination intensity or curvature in the exposure region. Then the elasticity deforming condenser lens 1 is subjected to tension or compression load to change the curvature radius. Through these procedures, the distribution of illumination intensity is controlled to equalize the dimension of exposure pattern.

IPC: H02P29/00
Filed: 1990-03-20
Abstract: PURPOSE:To reduce a dead zone by the static friction of a motor shaft generated when starting a movement and reduce an impulsive force when contacting with an objective body and stopping, by using a programmable filter as a high- pass filter when starting the movement and using it as a bandpass filter when contacting with the objective body and stopping, after a spatially moving state. CONSTITUTION:Commanding part 1 gives the value proportional to a desired force as a command value and performs the assignment of a band for a programmable filter 7 so that it operates as a high-pass filter. Waiting until a movement is possible to start, the assignment of the band is altered for the programmable filter 7 so that it operates as a bandpass filter. The bond to be altered is so set as to include the natural frequencies of an arm and an objective body. Waiting until the arm is contacted with the objective body, the movement is completed. Meanwhile, a controlling loop continues the processing in which a current detection value and a computation value are subtracted from a command value by a subtracter 2 and the resultant is fed to a power amplifier 3, and further, its output voltage is applied to a motor 5.

Filed: 1991-03-12
Abstract: PURPOSE:To shorten the head switching time by preliminarily correcting a track offset amount caused by the difference of a core width between plural magnetic heads in the data servo type head positioning system of a magnetic disk device. CONSTITUTION:At the time of a first STW writing, pieces of servo information 21 and 22 are written by successively shifting the core 19 of an (a) head and the core 20 of a (b) head (the difference of the core width 18) by every a half of track width(P/2). At the time of reading a track 21, a head 19 is controlled so as to follow the center of the 21, and at the time of reading a track 22, a head 20 is controlled so as to follow the center of the 22 so that it is necessary to move the head by an offset amount (x) at the time of switching the head. When this value (x) is measured, and the second STW writing is operated to the head (b) by adding the value (x), the position and the track at the time of the writing and reading of the head (b) are respectively 205 and 220 and it is not necessary to move the offset amount (x) at the time of switching the head.

Filed: 1979-06-06
Abstract: PURPOSE:To lengthen the life span of a gas discharge lamps by housing the first getter whose component is Ba in an exhaust tube, degassing and activating the inside of a glow tube, and lighting it with an exhaust system separated at the position containing the first getter. CONSTITUTION:The first getter 11 whose component is Ba is housed inside an exhaust tube and the second getter consisting of getter materials such as Ta and Zr is contained in a glow tube. After the degassing of the inside of the glow tube and the activation of the second getter are completed by the exhaust system which is connected to a vacuum pump, the exhaust tube is separated from the exhaust system on the glow tube side at the position where the first getter 1 is contained and the glow tube lights in this state. After impure gas produced is absorbed and removed by the first getter, the exhaust tube is chipped off near the glow tube. This removes the residual gas in the glow tube at the first getter and absorbs and removes the impure gas discharged from the glow tube material at the second getter. As a result, the life span of a gas discharge lamp can be lengthened.
