Title: Picture display device and display control method for the device
Inventor: YAMAZAKI TATSURO
IPC: G09G3/20
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To adjust the luminance of a picture displayed on a display panel without changing the value of an inputted video signal (picture signal). SOLUTION: The inputted video signal is converted into a digital signal to generate a one-line portion of picture data, and a column wiring of a display panel 14 is driven by an analog signal having the amplitude corresponding to this picture data. Synchronously with this driving, a row wiring of the display panel 14 to be driven for scanning is selected by a vertical shift register 9, and a signal having the pulse width indicated by a luminance adjustment part 6 is applied to this selected row wiring.  Since this luminance adjustment part 6 drives a PWM pulse generation part 8 so as to generate the signal having the pulse width corresponding to the luminance value indicated by a user, the pulse signal which has the pulse width corresponding to the value of the inputted picture signal and has the time width corresponding to the designated luminance is applied to each electron emitting element of the display panel 14, and thus, the quantity of electrons emitted from each element is controlled to adjust the luminance.

Title: Magnetic shielding sheet
Inventor: NAKANOUCHI YUKIO
IPC: B32B7/02
Filed: 1988-04-13
Abstract: PURPOSE:To obtain a shielding sheet which has large shielding effect and is abundant in flexibility, by arranging mixture with organic binder containing carbonyl iron powder, on a paper or a resin film, in a sheet type. CONSTITUTION:Mixture with organic binder containing 20% or more weight ratio of carbonyl iron powder of average grain diameter of 3-10mum is arranged on a paper or a resin film, in a sheet type. The carbonyl iron powder has characteristics approximate to sufficiently annealed pure iron. In the case of average grain diameter in the range of 3-10mum, the coercive force is small and about 60e. The permeability also is comparatively excellent, and shielding effect for high magnetic field is superior to other high permeability material with the same grain diameter. The grain shape of carbonyl iron powder is approximate to a sphere, and so high density filling is enabled. However, in the case where the weight ratio is equal to or less than 20%, the shielding effect decreases so largely that practical effect is lost.

IPC: G01M3/04
Filed: 1988-04-13
Abstract: PURPOSE:To rapidly and surely detect the slight leakage of sodium at the time of starting sodium detection and changing the operating state of a plant by deciding the leakage by the change rate of a sodium leakage signal. CONSTITUTION:A filter circuit 21 removes the contingent pulse signal and impulsive signal fluctuation of the sodium leakage signal 1. A time series data averaging circuit 22 determines the short-time average value of the sodium leakage signal from which noises are removed. A change rate detecting circuit 23 determines the change rate from the determined average value and the past several times and emits an alarm when the change rate exceeds the set value. An alarm deciding circuit 24 outputs a leakage decision output 3 when the alarm continues for the predetermined time. A change rate setting value calculating circuit 25 calculates and changes the set value of the circuit 23 by the temp. near the detection point. A computing period changing circuit 26 changes the computation period to meet with a signal level. The sodium leakage at the time of changing the operating state of the plant is thereby surely decided.

Title: Method of molding heat-meltable fluorine resin
Inventor: YOSHIMURA TATSUSHIRO
IPC: B29K27/12
Filed: 1986-04-17
Abstract: PURPOSE:To control an effect of a thermal stabilizer on a molded thing at a minimum, by applying melt molding to heat-meltable fluorine resin by making use of a mold in which a mold release agent layer containing the thermal stabilizer is formed. CONSTITUTION:At the time of melt molding of heat-meltable fluorine resin, a mold release agent containing thermal stabilizer of the heat-meltable fluorine resin is applied to the surface of a mold. Hot melt molding is applied to the heat-meltable fluorine resin by making use of the mold. A weight ratio of a mold release agent/thermal stabilizer is 1/0.1-1/10 and an application quantity of the mold release agent containing the thermal stabilizer to the mold is 0.1-3.0mg/cm<2> as pick up. By this method, as the thermal stabilizer is not compounded substantially with the fluorine resin itself, a highly pure molded product containing neither the thermal stabilizer nor the thermal decomposition residual is obtained. In addition to the above, thermal stability of resin at the time of the melt molding is secured sufficiently through the thermal stabilizer in a mold release agent layer which has been formed on the mold through application to the mold.
