Title: Echo prevention system and echo preventing circuit control method
Inventor: TAKEDA FUMIO
IPC: H04Q3/42
Filed: 1992-04-30
Abstract: PURPOSE:To control an echo preventing circuit irrelevantly to the quantity of use of a digital exclusive line. CONSTITUTION:When a telephone set 22 connected to a private branch exchange 21 is put in an off-hook state, a 1st subprocessor 23 informs a main processor 25 of that and sends necessary data out. The main processor 25 determines a line in use and sends loss data out to a 2nd subprocessor 24 which controls the corresponding digital exclusive line 28. The 2nd subprocessor 24 adjusts and controls the echo preventing circuit 26 on the basis of the loss data.

Title: Thermo-recording head
Inventor: SAWAE TETSUNORI
IPC: B41J2/335
Filed: 1977-09-16
Abstract: PURPOSE:To obtain a thermo-recording head which permits prompt restoration through simple operation if a diode goes out of order by providing spare diodes and signal lines. CONSTITUTION:Spare connecting areas (lands) 7b1...7b6 are provided to a signal line 7b and a heating element 2 and diodes 6b are conected by means of conductors 22. When the diode 6b1 goes out of order, a spare diode 20b1 is connected in place of the diode 6b1 by making use of the spar connection area 7b3. Although the spare diode 20b1 is positioned between the spare signal line 21b1 and signal line 7b, it is also possible to position the same in other places. Although the diode in which two electrodes are led out from one side is used, it is also possible to use the diode in which respective electrodes are led out from the two sides, front and back. In this way, the restoration of the functions may be readily and rapidly performed when the diodes go out of order.

Abstract: PURPOSE:To attain hand-free talking by switching automaticlly a transmission/ reception changeover switch depending on the presence or absence of voice input. CONSTITUTION:A signal inputted from a voice input section 1 is converted into a digital signal by an A/D conversion section 2 and stored in a buffer memory 4 of a signal processing section 3 only for a prescribed tine and sent to a modulation section 8. An input signal power calculation section 5 and an input signal zero cross number calculation section 6 calculate the number of times of zero crossings and the square sum (corresponding to signal power) of the date in the buffer memory 4 at every prescribed time. A switch control section 7 discriminates it as a voice period and silent period when the calculated value is a threshold level or above respectively and connects the transmission/ reception changeover switch 10 to the position of the transmission side while taking it as the voice input.

Abstract: PURPOSE:To produce a polymer dispersion which, when applied to outdoor paints, can form films having excellent durability, by polymerizing a vinyl monomer premixed with an ultraviolet absorber in the production of a nonaqueous polymer dispersion. CONSTITUTION:A solution is prepared by dissolving a polymer (e.g., one having an unsaturated double bond in the side chain, prepared by adding glycidyl acrylate to an octyl acrylate/acrylic acid copolymer) as a dispersion stabilizer in an organic solvent. Then 100pts.wt. vinyl monomer which dissolves in the above organic solvent when it is in the form of a monomer and does not dissolve in the above solvent when it is in the form of a polymer, is mixed with 0.1- 10pts.wt. ultraviolet absorber (e.g., benzophenone, benzotriazole). The resulting mixture together with an initiator is added dropwise to the above solution to polymerize the vinyl monomer. Thus the titled polymer dispersion consisting of the organic solvent and the ultraviolet absorber-containing polymer dispersed therein is formed.

Abstract: PURPOSE: To achieve the reduction in electrolytic voltage and prevention of hydrogen generation by applying the porous electrode comprising holding the catalyst capable of oxidizing and regenerating quinones in the electrolytic bath to cathode.  
     CONSTITUTION: The sheet of an active material layer 3 is made from the mixed cases of quinones, e.g., p-chloranil as well as active carbon and polytetrafluoroethylene or other. An expanded metal 1 of Ti alloy containing Mo and Zr is placed. On this are subsequently placed carbon paper 2, active material layer 3, expanded metal 1', active material layer 3 and porous polytetrafluoroethylene film 4 and the laminate is integrated by pressing. This electrode 4 is so installed in the electrolytic bath that its porous polytetrafluoroethylene film 4 makes contact to air and its other side makes contact to the electrolyte. The electrolyte penetrates in the fine pores of the active material layer 3 and the p-chloranil makes contribution to electrolytic reduction reaction. When the p-chloranil becomes of hydroquinone type  through reduction, the oxygen in the air subsequently diffuses through the polytetrafluoroethylene film 4 and the hydroquinone is regenerated to p-chloranil.

Abstract: A collecting piece incorporating a pair of relatively movable members which function as a valve to control the supply of a vacuum to all four milking cups of a quarter milking machine while maintaining the milk supplied from each of the milking cups separate from one another. Each of the lines connected to each of the pair of movable members of the connecting piece terminate in an opening which is flush with a sliding surface on each of the two relatively movable members. Thus, rotating one of the members relative to the other will either bring the openings into alignment with each other or cause the openings to remain out of alignment with each other. If desired, a locking mechanism can be provided for locking the two relatively movable members in the two positions thereof.

Filed: 1988-05-09
Abstract: PURPOSE:To equalize the temperature characteristic of the threshold voltage and reduce the changes of the current limitation value with temperature by using a transistor formed together with the base diffusion layer of a vertical MOS transistor in the same process and having a diffusion layer as a voltage limiting element between the gate and the source of the vertical MOS transistor. CONSTITUTION:A first transistor 1 includes a P type area 8 formed together with the P base diffusion layer 7 of a vertical MOS transistor in the same process and placed around a source 12. If the surface concentration of a P well diffusion layer 6 is made lower than that of the base diffusion layer 7 of the vertical MOS transistor, the threshold voltage of the first transistor 1 depends on the surface concentration of the area 8 formed together with the diffusion layer 7 in the same process to reduce the influence of the diffusion layer 6. This makes the threshold voltage of the first transistor 1 approximately the same as that of the vertical MOS transistor 3 and equalizes the temperature characteristics of the two with each other.
