Title: Oscillation prevention device of semisubmersible structure
Inventor: HAMASUNA JUNICHI
IPC: B63B39/00
Filed: 1987-11-25
Abstract: PURPOSE:To prevent the oscillation of the whole of a semisubmersible structure and its misregistration by inserting a piston type member which is extendingly provided longitudinally from the bottom portion of the semisubmersible structure into the water, into a cylindrical member which is projectedly provided longitudinally from the bottom of the sea to the water and is a steel pipe or the like, having suitable space. CONSTITUTION:One portion of submerged floating bodies 6 which are extendingly provided longitudinally from the bottom portion of a semisubmersible structure which supports a platform 8 above the water surface W by the submerged floating bodies 6 below the water surface W through columns 7, into the water through columns 7 is formed into a piston type member 1. On the other hand, the piston type member 1 is inserted having space 3 into a cylindrical member 2 which is a steel pipe and is driven into the bottom of the sea. When vertical force generated from all of the submerged floating bodies 6 due to waves is applied to the piston type member 1, the water enclosed in the cylindrical member 2 moves vertically passing through the space 3. The piston type member 1 is restrained in the cylindrical member 2 by means of suitably setting the space 3 so as to prevent the oscillation of the whole of the platform 8.

Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To provide an electronic watch reducing power consumption over the whole area of the living temperature range (-20 to 60 deg.C) and having low power consumption by using a metal material for the spindle of a step motor, and forming the surface of a spindle support section kept in contact with the spindle with a material having surface free energy of the prescribed value or below. SOLUTION: A carbon hard film 40 is formed at the portion of the spindle support section 20 of a rotor slid with a spindle 30. The carbon hard film 40 made of a material having the surface free energy of 50 dyne/cm<2> or below, for example, is used on the surface of the portion of the spindle support section 20 of the rotor slid with the spindle 30. An amorphous carbon film formed by the plasma CVD method in the hydrocarbon gas atmosphere and bound with hydrogan is used for the carbon hard film 40, for example. The spindle 30 is made of an SK material, and Ni plating is applied for preventing corrosion to the heat-treated surface to set to the prescribed hardness. A base material of PbBeCu is machined for the spindle support section 20, aging treatment is applied, and a DLC film is formed by the mask deposition method on the sliding portion with the spindle 30.

IPC: G02F1/137
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device with high contrast and good white/black display property by designing the liquid crystal to have specified wavelength dispersion of double refraction index and controlling the wavelength dispersion of double refraction index of the liquid crystal to less than a specified value. SOLUTION: This display device consists of a liquid crystal cell 2 prepared by holding a liquid crystal 7 having twisted alignment at between >=0 and <=70 degree between two substrates 4, 5 facing to each other, and a sheet of polarizing plate 1 applied on the cell. The liquid crystal used shows wavelength dispersion of double refraction index defined by the double refraction indices for light at 450 nm wavelength and at 590 nm wavelength, and has <1.05 wavelength dispersion ν of double refraction index Δn. The double refraction index Δn and wavelength dispersion ν of the liquid crystal have large positive correlation, so that in order to decrease ν, it is only necessary to decrease Δn. In order to decrease ν to <=1.05, a liquid crystal having <=0.07 Δn is used, and in order to decrease ν to <=1.1, a liquid crystal having <=0.11 Δn is used.

Abstract: PURPOSE:To make the quality of a product uniform by disposing a valve mechanism which opens a valve when the pressure of the molten metal in an injection sleeve rises to a prescribed value or above to the space between the injection sleeve and die space. CONSTITUTION:A cylindrical sprue bushing 22 is disposed to the central part of a stationary die 10 and the injection sleeve 16 is provided through a stationary platen 4. An injection passage 48 is formed of the bushing 22 and the sleeve 16.

Title: Solid-state image pickup element
Inventor: CHIBA YOSHIO
IPC: H04N5/335
Filed: 1986-12-11
Abstract: PURPOSE:To exactly execute an image pickup of a high speed object without using a special device, by adding a charge accumulated intermittently in a photoelectric converting element in one vertical period terms, in a vertical shift register, and transferring it to a horizontal shift register and outputting it. CONSTITUTION:Only while a gate pulse is in a high level, a charge is accumulated in a photoelectric converting element 1, therefore, it is accumulated intermittently three times in the element 1 in one vertical period term. Simultaneously, the charge is transferred to a first vertical shift register 2 and added. The added charge is transferred at a high speed to the second vertical shift register 7 immediately after a third transfer, and transferred to a horizontal shift register 9 by one line portion each in the subsequent one vertical period term. Also, a signal is outputted to the outside from a charge detecting part 10. This operation is executed intermittently three times in one vertical period term, therefore, even if the accumulation time is shortened, no discontinuous sensor is generated in an animation. In such a way, an image pickup of a high speed object is executed exactly.

Title: Peaking circuit
Inventor: SHIGA NOBUO
IPC: H03G3/00
Filed: 1987-11-24
Abstract: PURPOSE:To attain the automatic compensation of a characteristic variation in an FET by varying the capacity of a capacitor consisting of a diode by a side gate effect. CONSTITUTION:When a control voltage with a prescribed level is impressed from a terminal CD to a side gate means 10, the threshold level of the FET is changed by the side gate effect and the capacity between the gate and source of the FET is changed against the voltage between the gate and source of the FET. Even when the voltage between the gate and source of the FET is a certain fixed value, the capacity value between the gate and source can be controlled by the level of the control voltage impressed to the means 10 and the peaking frequency can be variably controlled. Since the output of an automatic compensating circuit 3 is applied to a compensating terminal CF, unfavorable influence exerted upon the FET 1 by the means 10 can be compensated.

Title: Howling preventing device
Inventor: KOSHIKAWA MASAMI
IPC: H04B3/20
Filed: 1985-12-26
Abstract: PURPOSE:To prevent the generation of howling prior to the convergence of an echo canceller and to reduce the frequency transient level of a frequency control device after the convergence of the echo canceller to reduce the change of sound by changing the frequency transient quantity in accordance with the echo attenuation value of the echo canceller. CONSTITUTION:Power detectors 11, 12 detect the power of respective signals Sin, Sout and an echo cancelling variable calculator 13 calculates an echo cancelling variable on the basis of the outputs L(Sin), L(Sout) of the detectors 11, 12. The echo attenuation variable signal is applied to a frequency control device 4 to control the frequency transient quantity. When the frequency transient quantity in the echo cancelling quantity calculator 13 is DELTAf, the frequency control quantity is controlled so that the shown formula e.g. is satisfied. Since the echo cancelling variable of the echo canceller 3 is small before the convergence of the echo canceller 3 and the variable is increased at the convergence, the frequency transient quantity in the frequency control device 4 becomes high before the convergence of the echo canceller, and after the convergence, the quantity is reduced by controlling the quantity as shown in the formula.
