Title: Manufacture of piezoelectric film
Inventor: SHIBATA YOSHIHIKO
IPC: H01L41/22
Filed: 1985-06-25
Abstract: PURPOSE:To facilitate the molding manufacture of a piezoelectric film and to make it a product being excellent in heat resistance and durability by a method wherein a calendering assistant is compounded in the mixture of dielec tric fine powder and polytetrafluoroethylene and a material thus prepared is molded into a film and then subjected to polarization. CONSTITUTION:Polytetrafluoroethylene (PTFE) is mixed in dielectric fine powder showing piezoelectric, pyroelectric or other electric characteristics, such as lead zirconia titanate (PZT), a calendering assistant is compounded in the mixture, and a material thus prepared is subjected to extrusion molding and then to calendering to be formd into a film of prescribed thickness. Then, it is subjected to polarization and thus a product is completed. Said film prepared by calendering is subjected to orientation to be formed into a porous film construction in which innumerable fine fibers are formed and connected in the shape of a spider web among minite knotting portions, and the gaps of holes of this porous film are impregnated with silicon rubber. Thereafter the film is subjected to polarization and thus a product is completed. As for the aforesaid dielectric fine powder, a mixture of barium titanate, lead titanate and lead zirconate or the like can be adopted in addition to PZT.

Title: Swing stop controlling method of crane
Inventor: CHINBE HIROSHI
IPC: B66C13/22
Filed: 1993-05-14
Abstract: PURPOSE:To make an effective swing stop performable as controlling the secondary swing of a hanging load. CONSTITUTION:A swing stop controllier of a crane separates a deflective angle of a hanging load W obtained by a deflective angle sensor 1 into a primary deflection component 3 and a secondary deflection component 4. In succession, a secondary swing stop controlled variable 8 and a primary swing stop controlled variable 7 are operated, and both these controlled variables are given to a crane travel driving device 10 after being compounded. With this constitution, both primary and secondary swing stop operations are performed at the same time, whereby the reliability and effect of primary swing stop control or the original object are thus improvable.

Title: Production of steel plate for abrasion resistance
Inventor: SHIRAI YASUTA
IPC: C21D9/52
Filed: 1980-09-30
Abstract: PURPOSE:To obtain an abrasion resistant steel plate of fine crystal grains and superior toughness by hot rolling a slab to intermediate thickness steel plates and carburizing these with the carburizers interposed between the plates then hot rolling down to product sizes and hardening the plates under specific conditions. CONSTITUTION:Continuously cast or bloomed slabs are hot-rolled to intermediate thickness steel plates, and plural sheets are superposed means of carburizers added with accelerators. The spaces between the opposite surfaces are hermetically closed with fire bricks, etc. These are heated for 5-15hr at 900-1,300 deg.C in a furnace, whereby the plates carburized on one or both surfaces are obtained. Following this, these are subjected to secondary hot rolling down to product sizes, after which they are immediately cooled down to 600-400 deg.C at >=30 deg.C/sec cooling rate, and are thereafter slowly cooled. Here, if the carburizing temp. is below the lower limit, a long time is required, and above the upper limit, the formation of coarse crystal grains occurs. The carburization time below the lower limit leads to insufficient carburization depth and that at the upper limit to the saturation of effect. In secondary rolling, the structure is made much finer, and the toughness better. The surface hardness is much improved by the cooling. The cooling temp. in excess of the upper limit results in imperfectly hardened structure and that below the lower limit in insufficient slow cooling owing to tempering effect.

Title: Color monitor device
Inventor: TOKUHARA MASAHARU
IPC: H04N7/03
Filed: 1990-05-29
Abstract: PURPOSE:To eliminate a delay time difference in a comb-line filter by inputting a signal not Y/C separation at a Y/C separator circuit, that is, a composite video signal in a vertical blanking period to a text decoder. CONSTITUTION:Line subtraction processing by an arithmetic circuit 14 in a Y/C separator circuit 11 is not implemented during a vertical blanking period. Thus, a test data superimposed during the vertical blanking period of a composite video signal is not changed but outputted from the Y/C separation circuit 11. Thus, when a text decoder 17 extracts a text data from an output of the arithmetic circuit 14, proper decoding is attained. Since the text data passes through the Y/C separation circuit 11, the delay time difference between Y and C signals due to the characteristic of a comb-line filter is not generated naturally. Thus, the time difference due to the comb-line filter is very easily eliminated in a video signal and a text signal.

Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To operate each kind of correction of image data by using a chart for correction without making this device large by setting a reference image being the reference of the correction of image data in a holding means. SOLUTION: An original pressing plate 22 attached to an original cover 21 is provided with a chart 30 for correction in which a reference image being a reference at the time of operating each kind of correction processing is displayed. At that time, the chart 30 for correction is directly printed on the original pressing plate 22, or the chart 30 for correction is printed on a film or the like, and this is adhered to the original pressing plate 22 so as to be provided at the original pressing plate 22. Thus, the chart 30 for correction can be prevented from being lost compared with the case that the chart 30 for correction is separately prepared, and it is not necessary to arrange the chart 30 for correction on an original placing plate 23 each time image data are corrected, and the chart 30 for correction can be prevented from being shifted.  Moreover, the chart 30 for correction is not incorporated in the case of an image inputting device 1 so that the image inputting device 1 can be set without being made large.

Title: Sample-and-hold circuit
Inventor: YOTSUYANAGI MICHIO
IPC: G11C27/02
Filed: 1991-06-11
Abstract: PURPOSE:To improve operating speed by providing a capacitance element in parallel to a switching circuit. CONSTITUTION:At the time of transferring from a sample period to a hold period, since potential difference between both ends of the switching circuit SW3 is generated, current flows to the switching circuit SW3. In the sample period, the capacitance element C3, as well is charged by input signal Vi voltage, at the time of transferring from the sample period to the hold period, charge on the capacitance element C3 is discharged. Thus, the change of the charge amount on a capacitance element C1 is smaller as compared to the usual sample-and-hold circuit, the change of the charge amount of the input end (-) of an operational amplifier 1, further, the potential change of the input end (-), as well is small. Thus, the setting time of the voltage of an output signal V0 is shortened and the operation is speeded up.

Abstract: PURPOSE: To generate electric power economically and without causing environmental pollution, by producing a current of fluid in water passages through utilization of differential pressure produced at the back of a weir, and turning power generating water turbines by the force of the current of fluid.  
     CONSTITUTION: In applying the principle of this invention to a ship, a proper number of water tanks 2 are formed in the body 1 of the ship, and sea water is introduced from respective sea water inlet parts 3 into the water tanks 2 to the level of waterline l. When the ship 1 starts to travel, a relative velocity difference is produced between the ship and sea water, so that virtual flow of fluid L is produced. Here, if a weir plate 10 is fixed at the front of each opening 5' formed in the bottom of the ship 1, water in the tanks 2 is drawn from outlet ports 5 to the outside of the ship 1 since vacuum is produced at the back of weir plates 10. That is, a current of sea water through the outlet ports 5 is produced, which serves to turn runners 8 of water turbines 6 and hence generators G. Although sea water is discharged from the ports 5 to the outside of the ship, corresponding amount of sea water is supplied into the tanks 2 from inlet ports 3.
