Title: Vinyl acetate resin emulsion and adhesive
Inventor: YOSHIKAWA HIROAKI
IPC: C08F218/08
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain an emulsion excellent in film-forming properties and viscosity even at a low temperature and also in workability, heat resistance, water resistance, storage stability, etc., by subjecting an ethylene/vinyl acetate copolymer emulsion containing a glycol ether to seed polymerization with vinyl acetate in the presence of a polyvinyl alcohol. SOLUTION: The content of a glycol ether in the ethylene/vinyl acetate copolymer emulsion (referred to as EVA emulsion hereafter) containing a glycol ether is preferably 1-15 pts.wt. based on 100 pts.wt. solids of the ethylene/vinyl acetate copolymer (EVA). The amount of the vinyl acetate resin to be subjected to seed polymerization with the EVA resin is preferably 200-700 pts.wt. based on 100 pts.wt. EVA resin. The amount of PVA added should be about 2-25 pts.wt. based on 100 pts.wt. total of the EVA and the vinyl acetate monomer for stabilizing the seed polymerization.

Title: Continuously variable mechanism for belt winding power transmission device
Inventor: KAWASAKI MASAMI
IPC: F16H9/16
Filed: 1988-10-25
Abstract: PURPOSE:To facilitate the axial movement of a relay shaft and carry out smooth continuous variation by differentiating the contact condition between a first belt and a first winding groove from the contact condition between a second belt and a second winding groove. CONSTITUTION:Both of the spreading angle alpha in the radial direction of a first winding groove 32 and the spreading angle beta of a second winding groove 33 are determined to be 20 deg.. However, the relative inclination angle gamma of both contact faces 58, 59 between a first belt 34 and the winding groove 32 is 26 deg., whereas, the relative inclination angle sigma of both contact faces 60, 61 between a second belt 38 and the second winding groove 33 is 22 deg.. Hence, due to the difference in the relative inclination angle, the axial component force of the pressing force of the second belt 38 which presses a partitioning portion 49 is larger than the axial component force of a reaction force which acts on the partitioning portion 49 from the first belt 34. Accordingly, it becomes easy for a relay shaft 50 to move in the direction of reducing the diameter of the pitch circle of the groove 33 and, since the relay shaft 50 is easy to move in the radial direction, smooth continuous variation can be performed.

Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To put image data of more than one page together into one page and output them to one printer while efficiently switching and controlling more than one printers. SOLUTION: A printer controller 2 supplies current setting parameters of one page and current image data to one printer 4 specified among the printers. If there is not an image data composition specification command among the current setting parameters when setting parameters and image data of a next page are outputted to the specific printer as next setting parameters and next image data, the printer controller supplies the next setting parameters and next image data to other printers except the specific printer on condition that a predetermined time is elapsed after the current image data are outputted. When the current setting parameters include the image data composition specification command, the printer controller 2 supplies the next setting parameters and next image data irrelevantly to the predetermined time.

Abstract: PURPOSE:To embody the integration of photoelectric converting elements by providing an electric conductor film whose contact area with an insulation material smaller than a contact area between a photovoltaic layer and the insulation material and making a serial connection between photoelectric converting elements which adjoin this electric conductor film. CONSTITUTION:A first conductive film 2 is formed on an insulation substrate 1. A photovoltaic layer 3 which comprises a pin type semiconductor layer is stacked and formed on the substrate 1 which includes the surface of the film 2. A laser beam is caused to impinge on an area in the film 2 formation position so as to separate the photovoltaic layer 3 into each pattern per element. Laser annealing is carried out under an oxygen atmosphere so as to form an SiO2 film 4 only on the side of the layer 3. A second electric conductive film 5 is deposited and formed with a specified mask, thereby obtaining a photovoltaic device. A contact area between the film 2 and the substrate 1 is adapted to be smaller than a contact area between the layer 3 and the substrate, thereby preventing the diffusion of elements (Sn) of the film 2 to a semiconductor layer.

Title: Erroneous detection preventing circuit for call signal
Inventor: MIDERA TAKAFUMI
IPC: H04M1/00
Filed: 1988-10-27
Abstract: PURPOSE:To prevent the erroneous detection of a call signal such as a dial pulse signal, etc., by providing an integration circuit to produce a mask signal having a required time constant by a current that flows on a telephone line, and a gate circuit to limit the output of a detection circuit by the mask signal. CONSTITUTION:When the dial pulse signal is sent after the off-hook of terminal equipment 1 is performed, a line current changes corresponding to the dial pulse signal. In other words, output 51 and output S2 change via photocouplers 2, 6, and 7. During the term of the break signal of the dial pulse signal, output 53 goes to an H level, however, the time constant by resistors R4 and R5 and a capacitor C3 in the integration circuit 9 on a preventing circuit side is set longer than the term of the break signal of the dial pulse signal. Thereby, the output signal S2 from a detector 4 is masked by the output signal S4 of the integration circuit 9, therefore, no signal CI is outputted.

Title: Echo cancelling method
Inventor: SATO YOSHIO
IPC: H04B3/23
Filed: 1985-12-04
Abstract: PURPOSE:To attain the elimination of echos with less operation quantity by selecting a sub-band maximizing power of transmission output to select the sub-band and correcting the approximated echo path response by the selected sub-band only. CONSTITUTION:Approximated echo paths 13-1-13-n combine an approximated echo signal at each sub band, the result is subtracted from a transmission input signal in subtraction sections 15-1-15-n to obtain a transmission output signal eliminating the echo. A band control section 17 controls a transmission output signal at each sub-band and inputs the result to a transmission output terminal 21 of the original band. A power detection section 18 detects the power of the transmission output signal of each sub-band and switches 14, 16, 19 select the sub-band having the maximum transmission output signal. A response correction section 20 corrects the impulse response of an approximated echo path with respect to the sub-band selected by the switches 14, 16, 19. Thus, the operation quantity required to correct the impulse response is reduced and the constitution of the equipment is reduced by incorporating the response correction section into one.
