Title: Measuring method using artificial magnetic lattice film
Inventor: YAMAMOTO HIDEFUMI
IPC: H01F10/10
Filed: 1992-09-10
Abstract: PURPOSE:To measure the intensity of an external magnetic field with high sensitivity by using an artificial magnetic lattice film having non-magnetic thin films and magnetic thin films alternately layered therein and measuring the change of the thermal conductivity of the film. CONSTITUTION:An artificial magnetic lattice film 1 is formed by laminating a plurality of (approximately 50) magnetic NiFe thin films 11, non-magnetic Cu thin films 12, magnetic Co thin films 13, and non-magnetic Cu thin films 14 on a substrate 10. A thermocouple gauge is formed in the substrate 10 to measure the change of the thermal conductivity. While the lattice film 1 is set opposite to a magnetic medium 2, the change of the thermal conductivity of the lattice film 1 is measured. The change of a leaking magnetic flux 3 from the medium 2 is measured from the relationship between the change of the thermal conductivity and magnetism, whereby a magnetic signal recorded to the medium 2 can be read. If the thickness of Cu films is changed, an area of a magnetic field where the thermal conductivity is greatly changed can be changed. Therefore, the structure of the lattice film 1 may be varied depending on the intensity of a to-be-measured magnetic field. Alternatively, Fe/Cr, Co/Cu and the like may be used for the lattice film 1.

Title: Shuttle type serial line printer
Inventor: ENDO KUNIO
IPC: B41J2/515
Filed: 1985-10-30
Abstract: PURPOSE:To make the timing of printing accurate, by forming a position detection pulse by making reference to three reference voltages set near the central level of a sensor output signal. CONSTITUTION:Because when the level of the signal Sa from an amplifier 314a is higher than a zero cross level Vc in a printing stop period Co, Sa is not lower than Vc at the end of a period Cl and the start of a period Cl, the voltage Eal of an amplifier 320a keeps '0' level. Then, the last pulse Pie is generated at the end te of the period Cl' and the first pulse Pis is generated at the start ts of the period Cl. Further, when the level of Sa is lower than Vc, Sa is lower than Vc at both ends of the period Cl' and the start of the period Cl. Thereby, the voltage Eal changes from '0' level to '1' level at the end of the period Cl', keeps '1' level during the stop period Co and changes from '1' level to '0' level at the start of the period Cl. As a result, the first pulse Pis is generated at the time ts.

Abstract: PURPOSE:To enable the separation and recovery of CO having high purity from a CO-containing mixed gas, smoothly, in high efficiency, by removing the impurities and water from the mixed gas pressurized by a pressure-swing method, converting the CO to CO2 with O2 existing in the gas, and adsorbing CO with a specific adsorbent. CONSTITUTION:A CO-containing gas such as converter gas generated from the converter of an iron mill is compressed to 0.12-9kg/cm<2>G by a compressor or a blower. The impurities in the compressed mixed gas, such as S compounds, NH3, etc. are removed by the adsorption to an adsorbent such as supported activated carbon, etc. Water is removed from the mixed gas by alternately switching two adsorption columns filled with zeolite or activated alumina by pressure-swing method, and at the same time, the adsorbent in the column out of operation is dried and regenerated. The small amount of O2 existing in the mixed gas is made to react with CO in the presence of a binary catalyst consisting of a partially reduced copper oxide and zinc oxide, and the produced CO2 is removed. Thereafter, CO in the mixed gas is adsorbed to a solid adsorbent capable of selectively adsorbing CO and prepared by supporting a cuprous halide and optionally aluminum halide on a carrier such as activated carbon, etc., and the adsorbed CO is desorbed and recovered.

Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To form a silicon oxide buried layer in a silicon wafer by a method, wherein a recess is formed in the silicon wafer, and light ions are injected at more shallow depth to form air bubbles, and the light ions are evaporated, and a cavity remains in a place of air bubbles for oxidizing the cavity via the recess. SOLUTION: If helium ions 3 are injected into the entire surface 2 of a silicon wafer 1, helium air bubbles 4 are formed at an average permeation depth of the ions 3. If the silicon wafer 1 is heated at a temperature of 700 deg.C or higher, helium diffuses to the surface 2 and a buried layer which is an empty cavity remains in a place of air bubbles 4. A recess or groove 5 is formed, so that its depth is deeper than the depth that the cavity 4 is installed and is divided into an upper portion 6a and a lower portion 6b. If the silicon wafer 1 is heated in a furnace at a dense oxygen concentration, the buried layer containing the cavity 4 is uniformly oxidized and a buried layer 7 of a silicon oxide can be formed in the silicon wafer 1.

Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor element having an irregular surface without using any chemical method, by forming a first-crystal-based semiconductor layer having a first crystal orientation, and by forming on the first-crystal-based semiconductor layer a second-crystal-based semiconductor layer whose crystal is grown in a different crystal orientation from the first crystal orientation. SOLUTION: A first i-layer 4 is formed out of a polycrystalline silicon having its crystal orientation of (111). Therefore, very fine protrusions 40 caused by grain boundaries are formed on the surface of the layer 4. Since the crystal orientation of the polycrystalline silicon is (111), the very fine protrusions 40 having their inclined surfaces A equal to (110) plane can exist on the surface of the layer 4. As a result, a second i-layer 5 made of a polycrystalline silicon having its crystal orientation of (110) is formed on the first i-layer 4. In this way, a semiconductor element having an irregular surface is obtained without using any chemical etching. Therefore, since the maintenance and management of solutions and the apparatus for processing waste etching liquidl can be made unnecessary, the manufacturing cost of a semiconductor element can be reduced.

Abstract: PROBLEM TO BE SOLVED: To increase an aperture rate per one picture element by transferring charges generated in a photoelectric conversion section n-times (n>1) for one vertical scanning period so as to reduce a width of a vertical register to 1/n. SOLUTION: A vertical transfer section 2 receives sequentially charges generated in a plurality of photoelectric conversion sections 1 arranged in 2-dimension for each vertical line and the charges are transferred n-times (n>1) for one vertical scanning period. A horizontal transfer section 3 receives sequentially for each horizontal line the charges read from the vertical transfer section 2 and transfers the charges n-times per one horizontal scanning period. An image synthesis means 4 adds image signals read from the horizontal transfer section 3 in terms of frames or fields by n-image patterns. Since scanning is conducted at a speed of multiple of (n) in this way, the charge amounts to be transferred are 1/n in comparison with conventional amounts and then the width of the vertical transfer section 2 is decreased to 1/n in comparison with the conventional device.  In order to decrease the effective horizontal transfer speed, vertical registers are divided and connected to a plurality of horizontal registers and outputs are multiplexed.
