Title: Wooden fireproof heat-insulating door
Inventor: SUMITA ATSUHIRO
IPC: E06B3/84
Filed: 1994-01-21
Abstract: PURPOSE:To improve fireproof heat-insulating properties and workability by connecting an edge material to the side face of a Paulownia-tomentose laminated board while burying a thermal foamed material into the edge material and bonding and working decorative materials to a surface and a rear. CONSTITUTION:A plurality of Paulownia-tomentose bonded material 1 are laminated and cemented by using phenol adhesives, etc., so that the fibrous directions are crossed in a Paulownia-tomentose laminated board 2, thus remarkably inhibiting warpage at the time of combustion. Cracks by shrinkage of a carbonized layer are suppressed by adhesive layers, thus improving fireproof-ness. An edge material 5 joined with the side face of the laminated board 2 supplies the holding power of the screw of the laminated board 2, and prevents the warpage of a door 8. A thermal foamed material 7 buried into the edge 5 is foamed at the time of the temperature rise of a flame, and seals a clearance between the door 8 and a door frame and interrupts the flame and smoke. Paulownia tomentose has excellent dimensional stability and fire resistance. Accordingly, a wooden fireproof heat-insulating door can be adapted to an A class fireproof door and a heat-insulating S type while workability can be improved because of light weight, and a waste disposal problem can be solved, and knob holding power can be increased because the edge material is used.

Title: Device and method for processing picture signal
Inventor: KONDO TETSUJIRO
IPC: H04N19/625
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To improve quality in a picture to be restored from a signal which is generated by compression encoding. SOLUTION: An input picture signal I restored from a compression picture signal is made into a block. A DCT(discrete cosine transformation) transforming circuit 32 creates a DCT coefficient value based on the signal which is made into a block. The value where a space frequency is in a middle area and a high area is extracted among the DCT coefficient ones and dispersion values are calculated based on them. When at least one of the dispersion values is smaller than a first threshold, a first flag is flagged. In the meantime, an adjacent pixel extracting memory 33 extracts the group of pixels being adjacent across a block boundary. A differential absolute value between the pixels is calculated and the number of times where the calculated value continuously becomes larger than the second threshold is counted by a continuity counting circuit 43.  When the counted value is larger than the third threshold, the third flag is flagged. When the first and the third flags are simultaneously flagged, the fourth flag indicating the position of a block distortion is flagged.

Filed: 1983-02-15
Abstract: PURPOSE:To protect an element region from a thermal breakdown by drawing out breakdown currents through the inside of a high-concentration well region formed around the element region when high voltage such as a surge is applied between a source and a drain. CONSTITUTION:A vertical MOS transistor is constituted by an N<-> type drain region 5, a P type well region 7, an N<+> type source region 8, a gate electrode 10, etc. A P<+> well region 20 is formed around an element region, and thedepth of the diffusion of the region 20 is formed up to depth deeper than the depth of the P type well region 7. In the vertical MOS transistor constituted in this manner, field concentration is generated at the corner sections 21 of the P<+> type well region 20 when inverse voltage at high voltage is applied between a source and a drain, and a breakdown is generated at the corner sections 21. Since the P<+> type well region 20 is conducted to a source electrode 11, breakdown currents do not flow in the element region, and are drawn out directly to the source electrode 11 through the inside of the P<+> type well region 20, thus prventing the breakdown of the element region.

Title: Video display device
Inventor: HAGA MINORU
IPC: G09G3/28
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a display technology that displays video signals with nearly the same luminance even when the video signals with different vertical frequencies are to be displayed. SOLUTION: A video signal S1 is displayed on a video display section 2, e.g. a plasma display panel PDP. A counter 3 that counts a vertical synchronizing signal S2 of a video signal S1 for a prescribed time counts the signal S2 and gives the result to an MPU 4, by which a vertical frequency is detected. The count of the vertical synchronizing signals S2 for one second is realized in a way that the counter 3 is reset by the MPU 4 that receives an interruption signal from a timer 6 set for one second and the MPU 4 reads the count of the counter 3 reset after one second.  Based on the detected vertical frequency, the MPU 4 uses a display luminance control processing section 7 to obtain a display luminance control variable according to a relation equation between vertical frequencies obtained through experiments and display luminance control variables and sets the result to a display luminance control section 1 that controls an amplitude of the video signal so that the display luminance of the video display section 2 is almost constant independently of vertical frequencies of the video signals.
