Title: Manufacture of magneto-resistance effect element
Inventor: HAYAMA NOBUYUKI
IPC: G11B5/39
Filed: 1982-08-10
Abstract: PURPOSE:To improve the surface of a polycrystalline substrate and thus prevent the characteristic damage of a MR element by a method wherein the substrate surface is coated with the hydrolized substance of a metallic alcoxide, and the magneto-resistance element is provided after heat treatment. CONSTITUTION:The compound M(ORa)m(Rb)n-m of alcoxide group ORa, alkyl groups Ra, Rb, and an n-valent metal M is soluble to lower alcohol, hydrolized to water or carboxylic acid, and can be adjusted in viscosity. The metal M is selected from Ti, Al, and Si according to the coefficient of thermal expansion of the substrate 1 or an insulator layer 2; when the level difference of the surface of the layer 2 is alleviated by coating this hydrolized substance and being heat- hardened, resulting in the sintering of an amorphous polymer 3, a surface roughness sufficiently larger than the molecule of the magneto-resistance MR element can be obtained. Sintering temperature is set at a temperature (370 deg.C or more) over the substrate temperature (250-350 deg.C) at the time of the formation of the MR element 4, and thus the reaction of the dissociated gas due to the advancement of the polymerization of the polymer 3 with the element 4 is prevented. This constitution enables to obtain a simple MR element.

Abstract: PURPOSE:To improve thermal stability and reliability by using an acryl/urethane graft copolymer, acryl/urea graft copolymer or acryl/urethane/urea graft copolymer formed by bonding an acrylic resin by either or both of an urethane bond and urea bond as a binder component. CONSTITUTION:The acryl/urethane graft copolymer, acryl/urea graft copolymer or acryl/urethane/urea graft copolymer formed by bonding the acrylic resin by either or both of the urethane bond and urea bond is used as the binder component. The thermal stability is, therefore, improved by the acrylic resin component having the excellent stability particularly to heat, light, chemicals, etc., and since the intramolecular flocculating force is simultaneously insufficient in the acrylic resin alone, the mechanical characteristics insufficient as the binder resin are made up by the urethane resin component. The thermal stability and reliability are improved in this way.

When a predetermined temperature (lower than an expected dew point by about 10 deg.C, and equal the lowest mirror temperature of -95 deg.C when a very low dew point is expected) is reached, the pump 25 is controlled 17 to inject about 5cm<3> of gas having a high water content through a valve 24 into the circuit 22. Consequently, the mirror 3 is coated directly with dew or mist. The measuring gas has low water content and normally guided at a current velocity of 20-40l/h along the mirror 3.  According to the arrangement, an initial mist layer 3 of sufficient thickness is formed at a correct time on the mirror 3 and the dew point can be measured in a short time.

IPC: H03F3/347
Filed: 1979-10-29
Abstract: PURPOSE:To make broad the adjusting range of bias current, by providing two film resistors for voltage division to determine the bias potential, on an integrated circuit. CONSTITUTION:A voltage fed to a bias terminal 6 gives a bias potential to the base of a transistor 5 via a resistance 1. A resistance 8 is provided between base and ground in parallel with a diode 2 for temperature compensation. The resistances 1 and 8 are formed as film resistances on an integrated circuit. In unidirectional adjustment to increase the resistance value with laser trimming, the increase in the resistor 1 causes the decrease in the base potential and the increase of the resistance 8 produces the increase of the base potential. That is, the bias current can be adjusted to both the directions of decrease and increase.

Title: Formation of oxide film
Inventor: FUKUDA HISASHI
IPC: H01L21/316
Filed: 1988-06-07
Abstract: PURPOSE:To form an Si oxide film by a simple process and, moreover, to make it possible to form the oxide film on a region as fine as a half micron or less as well by a method wherein an Si substrate is heat-treated intermittently on a rapid heating condition and the oxide film is formed only on a high-doped part in the Si substrate. CONSTITUTION:Impurity ions are implanted in a scheduled element isolation region forming region 25 of an Si substrate 21 to form a high-doped P<+> layer 23. Then, the substrate is intermittently heat-treated on a prescribed rapid heating condition to form selectively an Si oxide film 27 only on the P<+> channel cut-layer 23. Then, the substrate is doped with phosphorus using the film 27 as a mask by an implantation method to form an n<+> subcollector layer 29. Then, after an annealing treatment is performed in an epitaxial device to remove a natural oxide film on the surface of the layer 29, an n<-> Si layer (an epitaxial layer) 31 is made to grow thereon. As a high-doped part in the substrate particularly comes to a high-temperature state and is selectively oxidized thermally, the simplification of a manufacturing process is contrived and, moreover, the high-doped part can be formed into a very fine one by irradiating an ion beam of a very fine spot, for example.

Abstract: PURPOSE:To prevent quality of an image from decreasing by preventing abnormal temperature rise of a recording head by a method wherein when a head temperature detection means and a comparison means respectively detect and judge that temperature of a recording head is higher than standard temperature at which excellent recording is performed, even though start of recording operation has been indicated, a control means establishes standby time. CONSTITUTION:Though a recording head 10 records while it is being controlled so as to be generally, for instance, at a temperature near 35 deg.C by using a heat insulating heater 8, its temperature occasionally rises extremely high according to a use condition. A value to be obtained by adding a certain temperature margin to a value not to be reached in the case where recording is performed at a printing rate of a standard dot density, for example, for one sheet content of A4 sized paper, is selected as a threshold T1. Therefore, when the temperature of the recording head 10 is at this threshold T1 or lower, excellent image quality recording can be performed for at least one sheet. Then, a control part 50 obtains a temperature difference from output of a temperature sensor of the recording head 10 and of an outer temperature sensor 54, determines time corresponding to a condition, and stops electrification to a discharge heater 5 only for said time.
