Title: Semiconductor storage
Inventor: TAKAGI YASUHARU
IPC: G11C11/419
Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor storage capable of suppressing useless power consumption when it is used under condition lower than the maximum operating speed while securing the maximum operating speed. SOLUTION: This semiconductor storage is characterized by providing switches SW1 to SW3 among plural stages of sense amplifiers 22, 23, 24 to successively amplify pieces of data read from a memory cell array 21, selectively performing on/off control of the switches SW1 to SW3 according to levels of a switching signal SS inputted in an input pin 29 for switch setting of an internal circuit, increasing the number of stages of sense amplifiers to be cascaded in the case of high speed operation and reducing the number of stages of sense amplifiers in the case of low speed operation. Since the useless power consumption is suppressed by operating only necessary number of stages without unconditionally using all of the plural stages of sense amplifiers and all designed sense amplifiers are used in the case of high speed operation, the high speed operation is secured.

Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a device for fixing carbon dioxide, which is constituted so that moisture is prevented from being contained in a reaction gas being introduced into a reaction tank. SOLUTION: A reaction gas is introduced into a compressor 2 from a gas introducing port 1 and the pressure of the gas is increased, and then the gas is introduced into a HEPA filter 3 in which moisture is coarsely removed by the sticking effect. Thereafter, steam is removed by a mist separator 4 of a cooling coil system, and further the gas is cooled to a temperature lower than 0 deg.C with a evaporator of a gas cooler 5 using an alternate gas for a fluorocarbon as a cooling medium, thereby even small steam can be removed. Finally, the reaction gas is brought into contact with a cryo-panel of a liquid nitrogen cooler 6 at a very low temperature, thereby moisture can be removed almost completely. The reaction gas thus pretreated is introduced into a device 30 for fixing carbon dioxide.

Between the above-mentioned two cold rolling stages, the second cold rolling is done at 2-15% reduction of area in a direction at an angle of 45-<90 deg. with respect to the rolling direction of the steel sheet. By this method, the semiprocessed nonoriented silicon steel sheet increased in magnetic flux density in a direction perpendicular to the rolling direction of the steel sheet can be produced.

Title: Atomization agitator
Inventor: IIJIMA AKIRA
IPC: B01F25/60
Filed: 1990-12-11
Abstract: PURPOSE:To promote emulsion and dispersion of the material to be treated by consistently continuous treatment by taking out one part of this material to be treated from the lower part of a vessel while agitating the same by combination of both injection impact action and ultrasonic wave action and circulating it in a vessel. CONSTITUTION:The material to be treated is force-fed into a treatment vessel 1 from the injection nozzle 1, of a bottom face by a high pressure pump 8. This material to be treated is filled in the vessel 1 while it is circulated and fluidized upward from the lower part along the peripheral wall surface and, furthermore, to the lower part toward the central part. In the meantime, solid particles contained in the material to be treated are ultraatomized by collision with a diffusion board 5, and furthermore, by ultrasonic wave vibration due to an ultrasonic wave vibrator 3, thus emulsified and dispersed. One part of the treated material is taken out from a discharge port 6. Further, one part thereof is mixed into a supply pipe 10 via a circulation pipe 11 from a circulation port 7, again circulated and supplied into the vessel 1 together with the supplied raw material. Therein, when flow rate from the circulation port 7 is enlarged by a regulation valve 12 and opportunity of recirculation into the vessel 1 is made plenty, atomization and mixing in the vessel 1 are promoted.

Title: Manufacture of semiconductor device
Inventor: SAKAGUCHI JUNJI
IPC: H01L21/316
Filed: 1990-12-03
Abstract: PURPOSE:To prevent the rear of a semiconductor substrate from being oxidized and to relax that a stress is concentrated on the surface of the substrate by a method wherein, before an oxidation treatment by a selective oxidation operation, the rear of the substrate is covered with a remaining oxidation-resistant film and a formed oxidation-preventing film. CONSTITUTION:Silicon nitride films 12, 14 are formed on both faces of a semiconductor substrate 10; after that, the film 12 is etched selectively; the film 12 is left only in a region where an element isolation region is not formed; the film 12 is removed in a region where other element isolations are to be formed; a silicon oxide film 11 at the lower part is revealed. Then, while the film 14 is left on the substrate rear 10b, an oxidation treatment is executed; an oxidation operation progresses at the interface between the film 11 and the substrate 10 on the side of the substrate surface 10a; a thick silicon oxide film 16 is formed in a region where the film 12 has not been formed. Thereby, it is possible to restrain a stress from being caused on the side of the face 10b. A warp at the substrate 10 is formed in such a way that the face 10a protrudes, and it is possible to relax the stress at the end part of the film 16 on the face 10a. That is to say, since it is possible to relax that the stress is concentrated on the surface of the substrate, a leakage current or the like can be reduced.

Title: Production of multilayered magnetic recording medium
Inventor: CHINO NAOYOSHI
IPC: B05C5/02
Filed: 1990-12-06
Abstract: PURPOSE:To obtain the stable magnetic recording medium by setting the Raynolds number at the time of extruding a coating liquid for multilayered magnetic films at <=400 and the yield stress of coated layers at >=10dyn/cm<2>. CONSTITUTION:A liquid formed by mixing magnetic material powder with a binder and dispersant is dissolved into cyclohexane to prepare the magnetic coating liquid. The content of the cyclohexane in the coating liquid for the lower layer is set higher than the ratio thereof in the upper layer in such a case. Such coating liquid for the upper layer is extruded from a slit 5 and the liquid for the lower layer from a slit 6, by which the coating liquid is applied on a base 1 consisting of polyethylene terephthalate. While the base moves at a velocity (v), the base is dried by drying wind from above. The coating liquid is regarded as non-Newtonian flow and an important requirement is to maintain the liquid flow passing the slits 5, 6, etc., at <=400 Raynolds number. In addition, the disturbance at the boundary faces of the multilayered liquids is suppressed and the generation of unequal colors and longitudinal lines, etc., in the coated layers dried to solidify is obviated. The multilayered magnetic recording medium is thus stably supplied.
