Title: Shadow mask type color picture tube
Inventor: ENOMOTO TETSUYA
IPC: H01J29/07
Filed: 1988-09-07
Abstract: PURPOSE:To prevent deterioration of color purity by continuously connecting a plurality of slits in parallel with the edge of a skirt section through a bridging section to form a flexible section with uses a weld zone as a fulcrum and specifying the width of the flexible section and the length and width of the bridging section to install the weld zone of the flexible section keeping it away from the bridging section. CONSTITUTION:A plurality of slits 17 and 18 are continuously connected almost in parallel with the edge of a skirt section 16 of a shadow mask through a bridging section 19 to form a flexible section 21 which uses a welding zone 20 as a fulcrum. And the width a of the flexible section 21 and the length b and the width c of the bridging section 19 measure approx. less than 1/2 of the width d of the skirt 16, respectively, and also the weld zone 20 is installed at a position kept it away from the bridging section 19. So, an elongation of the shadow mask due to thermal expansion acts on the bridging section 19, where a conversion due to bend mainly occurs, and in case of the flexible section 21, a conversion mainly occurs due to twist, and the effective area of the shadow mask is converted to its peripheral direction, but not to the direction of a panel. Thereby, it is possible to prevent deterioration of color purity.

Title: Rubbing method
Inventor: HANIYU YUKIO
IPC: G02F1/137
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the transfer and C2 orientation of liquid crystal molecules and to improve the yield. SOLUTION: The feed speed (v) of a conveyor 13 is continuously increased from the start of rubbing (the time when the rubbing is started by contact of a rubbing roller 11 with the front end edge of a substrate E) to the end of the rubbing (the time when the rubbing roller 11 parts from the rear end edge of the substrate E) at the time of subjecting one sheet of the substrate E to a rubbing treatment. Such control of the feed speed (v) is executed similarly for the respective substrates E. The other rubbing conditions (roller rotating speed R, indenting rate (x), etc.) are held at desired values. As a result, the adequate range of the rubbing conditions is widened and the occurrence of the transfer and C2 orientation of the liquid crystal molecules is prevented even if the indenting rate (x) and the roller rotating speed R deviate slightly from the desired values.

Title: Gas permselective composite membrane
Inventor: SAITOU YUKIHIRO
IPC: B01D71/26
Filed: 1982-12-17
Abstract: PURPOSE:To obtain a composite membrane excellent in gas separability and gas permeability, by providing a silicone high-molecular layer excellent in film forming property between a layer comprising a high-molecular material excellent in gas separability and a support. CONSTITUTION:This composite membrane is obtained by forming a membrane 4 comprising a silicone high-molecular material having excellent film forming property and high gas permeability and a membrane 1 comprising a high-molecular material B of which the glass transition temp. Tg is an atmospheric temp. or less and which is relatively good in gas separability but inferior to gas permeability to the surface of a porous support 2. As the high-molecular material B, polyolefin, polybuten, polypentene, polymethylpentene or polyhexane are represented. Because this membrane has the layer 4 comprising the material good in gas permeability as a first layer, this layer 4 prevents the penetration of the high-molecular B-layer 1 into the support 3 and, therefore, the high- molecular B-layer 1 can be constituted extremely thin and gas permeability can be enhanced while gas separability is kept high.

Title: Method and device for restoring signal from partial information
Inventor: NAKAYAMA KENJI
IPC: H03H17/00
Filed: 1987-09-04
Abstract: PURPOSE:To reduce the number of times of calculations, and to prevent the amplification of an observation error by sampling an input signal by a frequency twice as high as an original signal band, and at the same time, adding a small random number matrix to the coefficient matrix of a linear equation when the original signal is modeled as the convolution integral of a certain input signal and a band limit filter. CONSTITUTION:The original signal xn is modeled as the convolution integral of the impulse response hn of the band limit filter and the signal xDn whose sampling frequency is 2fC. Since the spectrum of the original signal xn is limited within a cut-off frequency fC, the spectrum of xDn, obtained by sampling the xn by the frequency of 2fC, at 0<=f<=fC is perfectly the same as the spectrum of the xn. Accordingly, the original xn can be perfectly restored by letting the xDn pass through the band limit filter. Next, the matrix H generally becomes to have small eigenvalues, which amplyfies the error superposed on xPTn. Against this, the random number matrix R is added to the H. By weakening the correlation between the elements of the matrix in this manners, the amplification of the error can be suppressed to be small.

Filed: 1988-09-06
Abstract: PURPOSE:To aim at effectively activating neural cells, and to obtain an electrical stimulator by which various kinds of conditions of patients can be improved, by providing a circuit in which an anode electrode and a cathode electrode alternately deliver electrical rectangular wave signal outputs. CONSTITUTION:When a first transistor Tr1 is turned on, photocouplers Ph1, Ph2 connected thereto are energized, an output from the photocoupler Ph1 being transmitted through a resistor R5 and a diode D1 to a transistor Tr3 which is therefore turned on, and an output from the photocoupler Ph2 being transmitted through a resistor 7 and a diode D3 to an npn type transistor Tr5 which is therefore turned on. As a result, the anode potential energizes the transistor Tr5 so as to pass from an output terminal 14a to an output terminal 14b and then to reach a cathode potential, and brings the output terminal 14a, 14b to be anodic and cathodic, respectively, so as to deliver a rectangular wave signal. When a second transistor Tr2 is turned on, it brings the output terminals 14a, 14b to be cathodic and anodic, respectively so as to deliver a rectangular wave signal. Accordingly, when the transistors Tr1, Tr2 are alternately turned on, the output terminals 14a, 14b becomes alternately anodic and cathodic thereby it is possible to deliver alternate rectangular wave signals.
