Title: Production of shape memory alloy with high-temperature phase-transferring function
Inventor: DEI BUI GORUBAAGU
IPC: C22F1/10
Filed: 1995-10-27
Abstract: PURPOSE: To allow an alloy to memorize shape and to obtain sufficient shape recovery factor by subjecting a shape memory alloy with high-temp. phase-transferring function to cold working and then to a specific two-stage heat treatment. CONSTITUTION: A shape memory alloy with high-temp. phase-transferring function, in which martensite inverse transformation starting temp. (As) at the first heating after cold working becomes >=350 deg.C, is cold-worked and then heat-treated. At this time, as a first-stage heat treatment, heating is performed at a temp. higher than the martensite inverse transformation finishing temp. (Af) at the first heating for a time not longer than recrystallization latent time, e.g. at a temp. in the range between >500 deg.C and a temp. lower than the melting point of the alloy for <=3min. Thereby the structure of a bace material is transformed without causing recrystallization of the alloy to improve the shape recovery. Then, as a second-stage heat treatment, annealing is performed a temp. in the range between the plastic strain recovery temp. and the recrystallization temp.  It is preferable to use Ti50 Ni50-x Pdx (x=35 to 50 atomic %), Ti50-x Ni50 Zrx (X=22 to 30%), Ti50-x Ni50 Hfx (x=20 to 30%), etc., as the alloy.

Title: Ebullition refrigerant type cooling device
Inventor: SHIRAI KIICHIROU
IPC: H01L23/44
Filed: 1984-12-27
Abstract: PURPOSE:To obtain the device with which the cooling and insulation of the machine to be cooled are performed simultaneously by a method wherein an auxiliary chamber, which is communicated to the ebullition refrigerant chamber of an airtight casing and its inner cubic volume can be freely increased or decreased, is provided. CONSTITUTION:As the refrigerant vapor pressure of the refrigerant condensing chamber 3 of an airtight casing 1 is low at a low temperature, the surface of the liquid refrigerant 4 in a ebullition chamber 2 comes up, and the charged part of the machine 5 to be cooled sinks together with an auxiliary electric part 6. The empty space of the condensing chamber 3 is reduced, the condensing effect of the condensing chamber 3 is reduced, and the effect of cooling in lowered. However, as the temperature of the condensing chamber 3 is low, no effect is given to the cooling of the machine. The vapor pressure of the refrigerant goes up at a high temperature, the surface of the liquid refrigerant is pressed down, and auxiliary chamber 11 is expanded, space 13 is generated, and a cooling action is made active. The heating power of the attached part 6 is small, but as the temperature of the refrigerant is high and the saturated steam pressure is high even when the part to be insulated is exposed, the dielectric strength is high, and the insulation at the exposed charged part can be maintained properly.

Abstract: PURPOSE:To prevent an active base region from being diffused excessively by a diffusion of an emitter, to realize a fine base width and to enhance a high-frequency characteristic by a method wherein a high concentration layer is formed at the bottom of the active base region. CONSTITUTION:The following profile is provided: an active base region 14 and an emitter region 16 have a concentration grade which is tilted by a thermal diffusion from the surface; an impurity concentration by a high concentration layer 18 has a mountain-like protruding part inside an epitaxial layer; a concentration grade of the active base region 14 and a concentration grade of the high concentration layer 18 collide. Even when a diffusion of an impurity forming the active base region 14 progresses a little, a diffusion depth itself of the active base region 14 is not changed because it is stopped by the high concentration layer 18. As a result, even when a diffusion of the active base region 14 progresses, a diffusion depth xjB of a base is not changed; accordingly, it is possible to obtain an extremely narrow base width WB.

IPC: H01F41/14
Filed: 1985-12-17
Abstract: PURPOSE:To obtain a TbCo perpendicuarly magnetized film which has large stress inducing magnetic anisotropy by sputtering or evaporation by limiting the deposition speed of the TbCo film to within a specific range. CONSTITUTION:The deposition speed of a TbCo film on the surface of a substrate is specified as 250Angstrom /mm or more by using sputtering or evaporation for the means of forming the recording layer of an optical disk. In this case, the surface temperature of the substrate is desirable to be held at a temperature (100 deg.C or lower) which does not almost disperse a sputtered particle or an evaporated particle on the surface of the substrate. From this point of view, the upper limit of the deposition speed is specified as 1,800Angstrom /mm. Large residual stress is generated in the TbCo film by high speed film forming of 250Angstrom /mm or more without the relaxation of distortion by surface diffusion causing greater stress inducing perpendicular magnetic anisotropy and the square TbCo film which has good photomagnetic characteristics can be offered stably.

Abstract: PROBLEM TO BE SOLVED: To enable a liquid crystal display device to be reversibly transited only by an electrical stimulation between two different states with memory property by incorporating at least a smectic liquid crystal and dual frequency addressing liquid crystal in a liquid crystal composition. SOLUTION: The liquid crystal composition 16 comprises a smectic liquid crystal 17 with positive dielectric anisotropy and a dual frequency addressing liquid crystal 18. Besides the liquid crystal composition 16 looks transparent by the naked eye in smectic phase with a homogeneous alignment (a). Next, by applying a low frequency rectangular wave between an electrode 11 and an electrode 12 with a voltage applying means 15, liquid crystal molecules constituting smectic liquid crystal 17 and dual frequency addressing liquid crystal 18 rise toward the electrodes 11, 12 respectively. When the application of the low frequency rectangular wave is released, liquid crystal molecules constituting the liquid crystal composition 16 do not return to the homogeneous alignment held before the application of the rectangular wave but hold a risen state toward the electrodes (b).  Namely, the transition of the liquid crystal composition 16 to a white turbid state with memory property is attained by the application of the low frequency rectangular wave.

Abstract: PURPOSE:To enable the prevention of deterioration in magnetic characteristics even if a protective film is formed and to enable the retaining of excellent magnetic characteristics in an amorphous magnetic material, by performing protective coating partially on a core. CONSTITUTION:When a magnetic core 1 is formed by winding a coil around a core 11, which is formed of laminated amorphous magnetic material strips, through protective coating 2, the protective coating 2 is partially performed on a surface of the core 11. For example, the protective coating 2 and insulating coating 3 which are performed more thinly than the coating 2 are performed on a surface of the core 11 formed by winding a band-shaped ferro-amorphous magnetic material piece. The protective coating 2 is made to consist of protective coating 2a, which is performed on the corner parts of the core 11, and protective coating 2b, which is performed on transition parts for connecting corner parts of the core 11. The insulating coating 3 is performed so as to cover the core 11 and the protective coating 2. Hence, without effects of stress generated when coating resin is hardened and contracted, deterioration in magnetic characteristics can be prevented.
