Abstract: PURPOSE:To obtain a polarizing plate having superior heat resistance and moisture resistance by adhering a cellulose acetate film having a transparent thin film of a composition contg. SiO2, B2O3, BaO and Al2O3 in a specified molar ratio on the surface to the surface of a polarizing film. CONSTITUTION:A polarizing element such as iodine or Direct Blue 1 is adsorbed on a hydrophilic polymer film such as a polyvinyl alcohol film, and the film is stretched to orient the polarizing element. By the orientation, a polarizing film is formed. A transparent thin film of a composition contg. SiO2, B2O3, BaO and Al2O3 in a molar ratio represented by the formula is formed on at least one side of a cellulose acetate film such as cellulose triacetate film by vacuum deposition or other method. The cellulose acetate film is adhered to at least one side of the polarizing film so that the oxide layer contacts with the polarizing film. Thus, the desired polarizing plate is obtd.

Title: Etherifying method
Inventor: IZUMI YUUSUKE
IPC: C07C41/00
Filed: 1981-02-09
Abstract: PURPOSE: To obtain an ether simply and easily from an alcohol, by using a catalyst containing a carrier supporting a heteropoly-acid or a salt thereof on active carbon.  
     CONSTITUTION: An alcohol, e.g. an aliphatic alcohol such as methyl alcohol, is brought into contact with a catalyst containing a carrier supporting a heteropoly-acid, e.g. 12-molybdophosphoric acid, or a salt thereof on active carbon to give the corresponding ether. The catalyst containing the carrier is obtained by dissolving the heteropoly-acid or salt thereof in an organic solvent, adding active carbon to the solution, stirring the active carbon at ordinary temperature or the boiling point of the solvent for 30W60min, and filtering the active carbon. The etherification reaction is carried out by heating at or near the boiling point of the reaction system or in the vapor phase. The catalyst containing the carrier is supposed to have a very powerful adsorption or some chemical bond due to no elution even with a soluble medium.  
     EFFECT: The reaction product can be very easily separated from the unreacted raw material and the catalyst.

Title: Video signal processing circuit
Inventor: KONISHI MASASUKE
IPC: H04N19/169
Filed: 1990-01-26
Abstract: PURPOSE:To improve vertical resolution on a screen where there is a few noise and to decrease noise quantity on a screen where there is much noise by performing switching between scanning line interpolation and the averaging of a current signal by using a delay circuit which provides IH delay. CONSTITUTION:When an electric field intensity detecting circuit 110 outputs intense electric field, a control circuit 111 controls a changeover switch 105 so as to select the current signal, so an interlaced signal 101 is outputted, as it is, through the switch 105. A mean value and the interlaced signal 101 are outputted alternately as a double-speed interpolated signal 107. When the electric field intensity detecting circuit 110 is switched to a weak electric field, the control circuit 111 controls the changeover switch 105 so as to select the output of a shift register 104, so a mean value is inputted to an interpolating circuit 106 twice and the double-speed interpolated signal 107 has the same mean value twice continuously. Consequently, the vertical resolution is improved when an electric field is intense, and when the electric field is weak, the vertical resolution decreases, but a noise-free image can be obtained.

Title: Stabilizing method for surface protective film of semiconductor
Inventor: MAEKAWA TOORU
IPC: H01L21/324
Filed: 1978-02-16
Abstract: PURPOSE: To obtain a surface protective film which is stabilized with 1-digit lower interface level than that obtained through oxidation in the dried O 2 , by coating the Si 3 N 4  film on the semicnductor substrate and then oxidizing the film in the O 2  gas atmosphere containing the vapor.  
     CONSTITUTION: SiO 2  film 2 is formed about 1000Å thickness on the surface of Si substrate 1, and then Si 3 N 4  film is coated about 500Å thick on film 2 for a purpose of the alkali ion block. Substrate 24 of such lamination is put into diffusion furnace 25, and the O 2  gas which passed through demineralized evaporator 21 kept at about 90°C by heater 22 is sent there furthermore being heated up by heater 23. In this case, substrate 24 is heated previously up to about 1050°C, and about 30- minute heat treatment is given to form silicon nitride oxide film 4. As a result, a reaction is produced between O 2  in the water molecule and Si in film 3 to oxidize part of film 3, and the produced H 2  molecule is accumulated in film 3 and the Si 3 N 4  film. Thus, the interface level density is lowered for the substrate.

Title: Interphone system
Inventor: YAMAGISHI TAKATOSHI
IPC: H04N7/18
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption when an interphone is not used by detecting a video signal inputted to a video signal amplifying part and supplying power to the video signal amplifying part only when the video signal is detected. SOLUTION: A video signal outputted from a video controller 11 is modulated and outputted. The video signal is amplified by an amplifier 20 and is inputted to a detector 21. The detector 21 takes out a signal around a carrier frequency by a resonance filter and the signal is rectified by a rectifier. It is integrated and the value of the output signal of an integrated circuit is compared with a value which is previously set. A power switch 22 controls the supply of power to an amplifying circuit 23 based on a power ON/OFF signal from the detector 21. When the video signal from the video controller 11 is not outputted, the supply of power to the amplifying circuit 23 is stopped and the supply of power to the amplifying circuit 23 is started only when the video signal from the video controller 11 is outputted.  The amplifying circuit 23 receives the supply of power and executes an amplifying operation.

Title: Method and system for multi-address communication of digital video based on request
Inventor: JIYON EFU BOTOMUREI
IPC: H04N7/173
Filed: 1994-02-14
Abstract: PURPOSE: To obtain a method and system for giving digital video information to subscribers in response to requests from the subscribers through a subscriber's network. CONSTITUTION: A data server 160 manages many large-sized video data files containing video programming data to be multi-address communicated to requesting subscribers through a communication network. The requests from the subscribers are received at a gate way 30. The responses to the requests from the subscribers are made by sensing the subscriber's IDs and a video ID to a control server 100. The server 100 decides whether or not the subscriber queue to the video ID exists in the server 100 and whether or not the new subscribers are acceptable. When the queue exists in the controller 100 and the new subscribers are acceptable, the server 100 assigns the subscriber IDs to the queue and sends video confirmation, a port ID, and starting time to the gate way 30.  The gate way 30 allows a data switch 180 to connect its port to the subscribers by sending the port ID and subscriber IDs to the switch 180.

Title: Apparatus for removing rake residue or screen residue from liquid flowing through water channel
Inventor: HANSU GEORUKU FUUBERU
IPC: B01D29/25
Filed: 1988-01-29
Abstract: A device for removing material screened or filtered out of a liquid flowing in a channel. It consists of an unpowered cylindrical grating that merges into a screw-type conveyor. The grating slants down, partly immersed in the liquid, to the bottom of the channel. The bars of the grating extend over its total length leaving longitudinal interstices between them. The upward-sloping conveyor comprises a housing, a shaft, and a worm and conveys the screened-out material to a depositing point. The worm picks up the screened-out material as it scrapes the bars of the grating and conveys the material upward, constantly keeping the grating clean. The grating bars (8) are more or less triangular or trapezoidal in cross-section, with rounded-off edges, and positioned in such a way that one side (25) of the triangular or trapezoidal cross-section is oriented tangential to the circumference of the conveyor worm (16). The longitudinal interstice (10) is narrowest at the least possible radius at that point, adjacent to which its open cross-section (28) expands over-proportionally in the direction (32) traveled by the liquid. The grating bars that demarcate the longitudinal interstices are connected by outside bracing bars (9).
