Title: Method for manufacturing particle board
Inventor: NAKAYAMA HIROAKI
IPC: B27N1/00
Filed: 1988-03-23
Abstract: PURPOSE:To improve the adhesive property of isocyanate resin to a heating plate by a method wherein after amino resin powder is previously mixed with lumber chips and adjusted, chips are made into a board through applying isocyanate resin adhesive agent and the board is heat-compressed by the heating plate. CONSTITUTION:At first, the amino resin powder is mixed in sprinkling over to the chips being stirred as uniformly as possible, and the isocyanate resin adhesive agent is applied to the chips mixed with the amino resin powder. The chips applied with the adhesive agent is made into a mat-shaped board. The lumber chips made into a board is inserted between the heating plates and heat-compressed. By this method, in spite of using isocyanate resin adhesive agent, the chips in the surface of the particle board is not apt to be adhered to the heating plates, so that the particle board without formalin smell may be continuously produced with an excellent workability.

Title: Display operation device for automatic fire alarm equipment
Inventor: KONOO HIDEYUKI
IPC: G08B17/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To check an interlock between plural disaster preventing terminal equipments(DPTEs) on a screen even when these DPTEs are not practically connected to an automatic fire alarm receiver(AFAR) by changing the display of another DPTE interlocking with a selected DPTE at the time of storing interlocking data and selecting any one of the symbols of the DPTEs.

Title: Ccd shift register
Inventor: SHIRAKI HIROMITSU
IPC: H04N5/335
Filed: 1979-06-08
Abstract: PURPOSE:To evade blooming, based upon the saturation of a vertical shift register, even against intense incident light by greatly increasing the transfer charge of the vertical shift register in quantity. CONSTITUTION:Once transferred from a PN junction to shift register 108, electrons are stored in potential well S1 in area A1. As electrons increase in number, the potential of the storage area falls down to Vs. At this time, the electrons start interfering with the surface not in area S1, but in area S2. As electrons further increase in number, electrons start interfering with the surface in area A1 as shown by S3 and the potential of the electrons is obtained as VG-VFB (voltage applied effectively to transfer electrode). In area A2, on the other hand, electrons furthermore increases and when the quantity of charge accumulated at interface Si-SiO2 reaches a fixed value, the potential of electrons becomes VG-VFB.
