IPC: H01L43/08
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic detecting element which can be improved in detecting magnetic field sensitivity and can operate stably and the impedance of which does not change much even when the external magnetic field changes by further laminating a grounding conductor layer upon the lower surface of a platy dielectric member. SOLUTION: A magnetic detecting element 9 is provided with a platy dielectric member 11 having both upper and lower surfaces along a preset direction and a linear soft magnetic thin film 13 which is laminated upon part of the upper surface of the member 11, is elongated in the preset direction, and has a prescribed width and makes an electric current to flow between the input- output terminals 13-1 and 13-2 of the thin film 13. The element 9 detects a current change which is produced when a magnetic field is impressed upon the thin film 13 in a direction crossing the preset direction as a impedance change. In order to aggressively increase the capacity of the element 9, a grounding conductor layer 15 is laminated upon the member 11.  Therefore, the operations of the element 9 are stabilized, because not only the detecting magnetic field sensitivity of the element 9 can be improved, but also the impedance change becomes smaller even when the external magnetic field changes.

Abstract: PURPOSE:To form a high quality epitaxial layer on a semi-insulated substrate by forming a first semiconductor layer by the epitaxial growth method on a Cr- doped GaAs substrate, then forming a second semiconductor layer which forms the hetero junction with said first layer also by the epitaxial growth method and thereafter removing such second semiconductor layer. CONSTITUTION:A Cr-doped GaAs crystal substrate 1 is washing, degreasing and the surface thereof is etched. Thereafter, it is placed in an MBE apparatus and the surface of said substrate is purified through temperature rise under the vacuum condition and an undoped GaAs layer 2 is formed by the epitaxial growth method. After forming an N type GaAs active layer 3 on said layer and forming Al0.2Ga0.8As layer 4 which forms a hetero junction with the GaAs layer 3 by the epitaxial growth method, only the Al0.2Ga0.8As layer 4 is etched by the iodo etchant. Since Cr segregated at the surface is all included in the Al0.2Ga0.8As layer 4, it is perfectly removed by such etching and an N type GaAs active layer 3 is not adversely influenced by the etching selectivity. After this process, a GaAs MESFET is completed by forming the source, drain and gate electrodes.

Filed: 1986-10-17
Abstract: PURPOSE:To print to correct density by deriving a density average value for executing a density control and a density average value for executing a color control, and controlling an exposure by using a functional expression in which these density average values are variables. CONSTITUTION:A CPU44 reads out three color densities of each picture element from a ROM46 and divides them into a first image area 56 and a second image area 57. From density values of each picture element contained in the area 56, a density average value is derived, and from each picture element contained in the area 57, a density average value is derived. By using these density average values, a functional expression F for controlling the density, and a functional expression Fi for controlling the color are calculated. Subsequently, an exposure quantity is calculated from an exposure quantity operational expression in which two pieces of functional expressions F, Fi are add terms. The exposure quantity which is obtained is sent to a filter adjusting part 19, and a color filter of a complementary color to the corresponding color is drawn out of a standard position, or inserted toward the center of a printing optical path 20. In such a way, the insertion quantity of color filters 16-18 to the optical path 20 is adjusted, and three color optical components of a printing light are adjusted.

Abstract: PURPOSE:To enable the selectively deposited layers to be formed on a distortion layer without the occurrence of dislocation inside an active layer by a method wherein a layer having the same lattice constant as that of a substrate is provided near the junction interface between redeposited layers and the active layer inside the redeposited layers. CONSTITUTION:Firstly, an n-type In0.2Ga0.8As channel layer 2, an undoped Al0.3Ga0.7As layer 5 are successively crystal-deposited on an undoped GaAs semiconductor substrate 1. Later, SiO2 is deposited and then removed excluding the part to be the underneath part of a gate electrode 8. Next, the AlGaAs layer 5 is etched away using the residual SiO2 as a mask. Next, GaAs redeposited layers 3 and InGaAs redeposited cap layer 4 are successively deposited using a substrate selective deposition process e.g. organic metal vapor deposition process. Furthermore, source.drain electrodes 6, 7 are formed. During these process, dislocation (X) occurs between the GaAs redeposited layers 3 and the InGaAs redeposited layers 4. However, since both sides of the interface are highly doped to be of an n-type conductivity, the increase in the parasitic resistance due to the dislocation is to be negligible. Furthermore, the occurrence of the dislocation near channel can be restrained by providing the GaAs redeposited layers 3 even if the InGaAs layer 2 is used a as channel.

Abstract: PURPOSE:To smoothly generate sentences by comparing the converted result of pre-correction and post-correction and automatically registering a word in a different part in a dictionary. CONSTITUTION:When a character string is inputted and Kana (Japanese syllabary)/Kanji (Chinese character) conversion is executed, an initial converted result is stored in an initial converted result storage part 14. When the converted result is an objective conversion, a system comes to a subsequent input queue as it is. When it is not the objective conversion, a Kana/Kanji conversion conversion processing part 13 executes Kana/Kanji conversion so as to attain correction. A corrected result by a correction operation in the Kana/Kanji conversion processing part 13 is stored in a corrected result storage part 15, compared with the initial converted result in a converted result comparison part 16 so as to detect the different part in the character string, and the reading is detected from an input character string storage part 12. The reading detected in a word registration part 17 and notation are registered. When the word previously exists in the dictionary, the word is learned, and when it does not, the word is registered.

Abstract: PURPOSE:To eliminate the need for a high-pressure pump by sucking a slurry suspended with a packing material into an injection cylinder and forcing the slurry from the injection cylinder via a connecting tube into a guard column. CONSTITUTION:A slurry 4 suspended with a packing material is sucked into an injection cylinder 1 and thereafter said column is connected by a connecting tube 2 to a guard column 3. The operator pushes the cylinder after the connection to force the slurry 4 into the column 3. A solvent for pressurization may be passed thereafter if necessary. Only the injection cylinder is removed in such a case and after the solvent for pressurization is filled in the injection cylinder, the injection cylinder is reconnected to the column and the cylinder is pushed to force the solvent into the column. The need for a high pressure pump used with the conventional wet packing method is eliminated by such method and the connection and removal of the packing device and the column are made easy.

Abstract: PURPOSE:To prevent a brushing noise coming from the opening of an end bracket from being discharged to inside of cabin from a blowout hole together with winds by providing a wall on a mounting foot for fixing an electric motor to a scroll casing. CONSTITUTION:A fan 8 attached to a shaft 7a is rotated by rotating a rotator 71 by means of an electric motor 7. Further, a part of blowing wind is introduced into inside of the electric motor 7 from a scroll casing 4 through a cooling hose 10 so as to cool the rotator 71, a brushing device 72 and so on, and then returned from the opening 73a of an end bracket 73 to the scroll casing 4. At this time, a sliding noise generated between the brushing device 72 and the rotator 71 leaks to the electric motor 7 together with wind and reaches the scroll casing 4 from a slight slit between the drum 8b of a fan 8 and the wall 75 of a mounting foot 74. However, the noise can be reduced by reflection of the most part of the noise at the wall 75.

Title: Magnetic disk device
Inventor: KAIDA KATSUHIKO
IPC: G11B21/10
Filed: 1987-09-30
Abstract: PURPOSE:To shorten a data-read-unable time at the time of changing the selection of a magnetic head by controlling the positioning of respective magnetic heads with use of the intermediate position between the magnetic head of maximum amount of thermal off-track and the magnetic head of minimum amount as a reference phase. CONSTITUTION:At the time of reading sector servo information, the gain of an AG amplifier 9 is fixed, and a servo signal is peak-held in a peak holding circuit 13. Thus peak-held signal is fetched in a microprocessor 15, and the processor 15 calculates the off-track length of a head. From among this off-track length and those measured before this data, the maximum value and the minimum value are taken out. The processor 15 outputs offset data to a D/A converter 22 so that the sum of said two values come to zero. Out of this off-set data and a positional signal outputted from an LPF 18, a control circuit 21 transmits a control signal to a voice coil driver 23 in order to position a magnetic head 2. As a result, the average value of the amounts of correction for the respective heads 2 is reduced, hence an access time is shortened.

Abstract: PROBLEM TO BE SOLVED: To provide a building unit and a unit building improved in productivity. SOLUTION: In an inner balcony unit 40 serving as this building unit, outdoor aerated lightweight concrete plates 51 provided at a balcony, and indoor aerated lightweight concrete plates 52 provided indoors, are laid in the intersecting state of the respective longitudinal directions. The support parts and support positions of the respective aerated lightweight concrete plates 51, 52 are therefore different, so that only the supports for fitting the indoor aerated lightweight cellular plates 52 need to be fitted to an intermediate beam 44, and there is no need to fit supports for supporting the concrete plates 51. The fitting structure of the aerated lightweight concrete plates 51, 52 is thereby simplified to improve the productivity of the building unit 40.

Title: Clamping device of molding machine
Inventor: AOKI KATASHI
IPC: B29C33/24
Filed: 1983-12-30
Abstract: PURPOSE:To contrive to simplify a mold clamping device by using a powered mold clamping cylinder for the cylinder closing the mold at high speed. CONSTITUTION:The front inner diameter D2 of the cylinder member 7 of a clamping cylinder 6 is formed to be larger than the rear inner diameter D1 thereof, giving the difference between its front inner diameter and rear inner diameter. While the piston with the outer diameter fitted to the front inner diameter D2 is moved to the front from the rear of the cylinder, the pressurized oil in the front side is caused to flow to the rear side from the gap formed at the periphery of the piston 11, thereby reducing the oil pressure resistance in the front side at mold closing and simultaneously increasing the oil amount in the rear side. Accordingly, if the mold clamping cylinder is used for mold closing, the supplied amount of pressurized oil required for mold closing is sufficient to be little, and the mold closing may be carried out at high speed. Moreover, this device is different from the former device in which the front and the rear of the cylinder is connected, opening and closing the through hole bored on the piston by a disk valve. Because the valve or the oil pressure path, etc. requiring manual operation is unnecessary to be provided, the high speed mold closing is carried out by using the clamping cylinder, and yet its structures is simple and there occurs no trouble.

Abstract: PURPOSE:To make the best use of a recording area on a magnetic tape and to record data at a high density by dividing a head scan section on the tape into plural parts and alternately arranging recorded sections and non-recorded sections. CONSTITUTION:A recording control circuit 11, which fetches data signals from an information source 10 and leads them to recording heads 5 and 7, impresses data signals to be recorded corresponding to the divided sections in synchronization with the rotating phases of the rotary recording heads 5 and 7 through a recording amplifier 12. Reproduced signals that reproduction heads 6 and 8 reproduce are led to a comparator circuit 14 through a reproduction amplifier 13, and compared with having been recorded data stored in the recording control circuit 11. If they are non-coincident, the recording control circuit 11 is controlled so that the data is again recorded in the next section. When they are coincident, next data is fetched from the information source 10, and the recording control circuit 11 is controlled so as to record the data in the next section. Thus information can be efficiently recorded on the tape.
