Title: Forming method for ferroelectric thin film
Inventor: WATABE JUNICHI
IPC: C23C14/34
Filed: 1987-06-26
Abstract: PURPOSE:To make it possible to easily form perovskite type crystal structure by executing sputtering by controlling the power to be applied to each target while irradi ating ultraviolet rays in the specified condition on the board surface in the sputter gas atmosphere. CONSTITUTION:A board 33 not to heat, two targets 35, 36 which consists of each constituent metal element of ferroelectric film or each constituent metal oxide and are so formed as to oppose the board 33, and an ultraviolet rays irradiation light source 39 such as deuterium discharge tube for film anneal, etc., are arranged separate ly in a sputter container 31. And the light whose wave length is 400-450nm is irradiat ed from the ultraviolet rays irradiation light source 39 onto the board 33 surface inside the sputter gas atmosphere and the sputtering is executed by controlling the power to be applied to each target 35, 36 so that the filming element composition ratio may be 0.5-2.0. Accordingly, compounds such as Pb2Ti2O3 as well as PbTiO3 are also formed in filming, and the ultraviolet rays whose wave lengths are 400-450nm are absorbed and converted into heat by them, thus the structure is changed into stable PbTiO3 by the anneal effect. Hereby, the ferrodielectric film in perovskite type crystal structure that meets the stoichiometry composition ratio of the filming constituent element can be obtained easily.

Title: Viterbi decoder and decoder for convolution code
Inventor: KODAMA TOMOKO
IPC: H04L25/08
Filed: 1992-06-19
Abstract: PURPOSE:To reduce a decoding delay time without deteriorating a decoding rate by using at least one data among data inputted newly to each shift register and selecting a survival path this time. CONSTITUTION:A branch metric calculation circuit 9 calculates a branch metric of reception signals r0, r1 received from an input terminal 8 and outputs it to an ACS circuit 10. The ACS circuit 10 selects a maximum likelihood path able to be transited to each state from the path metric calculated by the accumulation of the branch metrics. When a survival path is revised, a Viterbi decoder does not use oldest bit able to be designated when the state is transited as a bit added newly for the revision of the survival path but uses a new bit. Thus, the decoding delay time is reduced more than that of a conventional decoder. A decoding delay time is made equal to a stop length by using a bit at a location representing newest information especially in the coder among bits expressing the state of the transit destination.

IPC: G06F3/06
Filed: 1978-12-21
Abstract: PURPOSE: To reduce the search time, by designating the track area to be searched and performing the key search only at the track.  
     CONSTITUTION: The channel interface CIF of the input and output control unit IOC receives the command and inputs it to the command interpreter CM. When the command is interpreted as the area designation of key search, the interpreter CM transfers the track information of the disc memory unit to the track information memory unit TBM and stored, and also, the key information is stored in the buffer KM. To the unit TBM, the head track and end track of each area of the key search are stored. When the interpreter CM interpretes the seek command, the disc DSC positions the magnetic head to the specified cylinder position, the search whether or not the designated key is present is started, and when the desired key is searched, the interruption for the start of transfer of read/write is made.

Title: Apparatus and method for positioning control of magnetic head, and recording medium with control program recorded
Inventor: NARISHIMA TORU
IPC: G11B21/10
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To correct the swell of a magnetic-head servo signal by measuring runout correction data used to reduce a synchronous runout and recording the data into a servo signal on a magnetic disk so as to be controlled. SOLUTION: The swell waveform of a magnetic-head position signal due to a runout is approximated by a Fourier coefficient. Thereby, the rotation synchronous component of the runout which is synchronized with the rotation of a magnetic disk is measured automatically, and runout correction data is created. Then, phase-difference correction data on a magnetic-head position signal generated in an inner circumferential track and that in an outer circumferential track due to an eccentricity are created, and the runout correction data is corrected by a gain adjusting operation with reference to a radial position.  When a magnetic head is positioned actually, the stored runout correction data is read out simultaneously with the magnetic-head position signal, a rotation- synchronous-error correction value is added to an actual position error signal, the position error signal of a magnetic head is positioned in a desired track position by using the corrected position error signal.

Title: Apparatus for preventing cavitation of water-cooled engine cooling device
Inventor: KOKUBO AKIHISA
IPC: F01P7/16
Filed: 1989-06-23
Abstract: PURPOSE:To prevent cavitation from occurring without a large space required by operating a pressure device with a freezing cycle device. CONSTITUTION:A freezing cycle device comprising a compressor 40, condenser 41, an evaporator 42, an expansion valve 44, a pressure electromagnetic valve 32, a pressure reducing electromagnetic valve 35, etc., is connected to a pressure chamber 22b of a pressure device 20. The pressure electromagnetic valve 33 and the pressure reducing electromagnetic valve 35 are opened/closed according to the number of rotations of an engine 10 and the temperature of engine cooling water. When the pressure electromagnetic valve 32 is opened and the pressure reducing electromagnetic valve 35 is closed, high pressure coolant is fed from a first bypass tube 30 into the pressure chamber 22b causing an adjuster 24 to be moved by the pressure of the high pressure coolant. Thus the adjuster 24 applies pressure to engine cooling water circulating in an engine cooling device to raise the pressure in the engine cooling device. Therefore occurrence of cavitation can be prevented without necessity of a large device but only with a simple structure.

Abstract: PURPOSE:To manufacture a extremely low carbon nitrogen steel, by blowing inactive gas and mixed gas of inactive gas and oxygen in molten low carbon stainless steel manufactured by oxygen blowing under reduced pressure in the existence of molten slag having a specific component under reduced pressure continuously. CONSTITUTION:The ladle 1 put in molten high carbon stainless steel 2, is taken in the vessel 4. Pressure of the vessel 4 is reduced and Ar gas is blown from the bottom-blown porous plug 3 of the ladle 1 and then, the molten steel 2 is stirred. At the same time, decarbonization refining is carried out blowing pure oxygen gas against the surface of the steel 2 from the top-flown lance 5. Pratial pressure of CO generated by the above decarbonization reaction, is low because the pressure of the vessel is reduced and carbon is removed in the limits of about C<0.01% without oxidizing Cr. Next, 2.5kg of the molten slag 6 per one ton of the steel 2 having the basicity of 0.5 or more, is added to the steel 2 under reduced pressure continuously and the lance 5 in dipped in the steel 2 preventing the absorption of very small of N and then, Ar gas or mixed gas of Ar and O2, is blown in the steel 2. The steel 2 is decarbonized moreover reacting contained C with O2 in the steel 2 and extremely low carbon nitrogen stainless steel containing C<0.005%, N<0.007%, is obtained.

IPC: H01L21/82
Filed: 1989-06-23
Abstract: PURPOSE:To automatize the correction of a net list by extracting data related on a subject to be moved from a moving source block adding data corresponding to extraction data to a moving destination block based on block data of high hierarchy and executing the setting processing of a new terminal if necessary. CONSTITUTION:Data related on the subject to be moved is extracted from the moving source block B1. The moving processing is executed for all extraction data. The moving processing basically consists of the deletion of data from the moving source block B1 and the addition of data corresponding to data for the moving destination block B2. A part to which data is added in the moving destination block B2 can be decided by referring to block data in the high hierarchy. If the setting of the new terminal is required for executing the moving processing, the new terminals are set in both moving source/moving destination blocks B1 and B2, and information on the new terminals are added to block data of the high hierarchy. Thus, the correction of the net list can be automatized.
