Title: Liquid crystal display device
Inventor: NISHI SHINICHI
IPC: G02F1/1335
Filed: 1985-10-25
Abstract: PURPOSE:To enhance contrast in a liquid crystal display having a liquid crystal compsn. provided between a pair of polarizing element by specifying an angle of twist of the liquid crystal molecule, and specifying the angle between the axis of polarization of the polarizing element and an optical axis of the liquid crystal molecule. CONSTITUTION:A liquid crystal layer C is formed between substrates 1, 2, and polarizing elements 9, 10 are provided to both sides of the liquid crystal layer C, and the angle of twist alpha of the liquid crystal is regulated to 80-100 deg.C. Further, the angle between an polarizing axis of the polarizing elements 9, 10 and the direction of the liquid crystal molecule contacting the surface of the substrates 1, 2 has slippage angle beta, gamma or 40-50 deg. in the direction of twist of the liquid crystal molecule. Furthermore, nematic or cholesteric liquid crystal is used as the liquid crystal molecule. Since the intensity of transmitted light due to impressed voltage is increased by thus specifying the direction of the polarizing axis of polarizing element, the contrast is enhanced by a higher time sharing driving method, a large picture plane of wider angle of field of view may be realized.

Title: Winding-type electronic component, sealing resin, and filler
Inventor: OGAWA HIDEKI
IPC: H01F1/37
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a sealing resin which has a stable characteristic and a stress resistance by maintaining superior magnetic shielding effect and, at the same time, controlling the particle size of a ferrite material used as a filler. SOLUTION: A sealing resin 28 is prepared by mixing a ferrite powder 60 obtained by mixing materials respectively composed mainly of Fe2 O3 , NiO, ZnO, and CuO together, baking the mixture, and pulverizing the baked product in an epoxy rein 62. The sealing rein 28 is applied to the winding section of a component. Since the filler of the sealing resin 28 contains NiO, ZnO, and, particularly CuO, the baking temperature becomes lower than the conventional temperature, and the degree of aggregation of particles drops, resulting in an uniform grain size. Therefore, the uniformity of the sealing resin 28 is improved, and the magnetic characteristic of the resin 28 is stabilized.  When bismuth oxide, silicon oxide, and lead oxide are added to the resin 28, in addition the stress resistance of the resin 28 is improved, because the Pi, Si, and Pb of the oxides stays at the grain boundaries of the ferrite particles as a buffering agent.

Abstract: PROBLEM TO BE SOLVED: To establish an evaluating and confirming method of the slow speed of oxygen transmissivity and an oxygen transmitting part by sealing an oxygen transmissivity measuring composition whose sol or solution having an indigoid pigment dispersed thereto has white or an opaque pale color when changed to a solid matter, and observing the change with the lapse of time of the pigment. SOLUTION: A composition 2 is solidified in a packaging container 1 having the composition 2 sealed therein, and allowed to stand in the atmospheric pressure or the like to observe the change with the lapse of time of the pigment of the composition 2. The slow speed of oxygen transmissivity of the material is evaluated by the change of color appearing on the whole surface, and when the pigment in the composition in the position P of a pinhole 4 or the position Q of a crack 5 is changed to bluish violet or blue, it can be specified and confirmed that the positions P, Q are oxygen transmitting parts.  The composition 2 can be used for comparing the slow speed of oxygen transmissivity as the material of a packing container having oxygen barrier property and visually confirming a part reduced or deteriorated in oxygen barrier property of the container by use of the pigment discolored by oxidation of the oxygen penetrated from this part.

Title: Equipment and method for data communication
Inventor: OIKAWA TAKEYA
IPC: H04M11/00
Filed: 1994-09-30
Abstract: PURPOSE: To continue communication even when the interruption signals of a call-waiting are present during data communication by providing a memory for storing that the call-waiting is present along with the time information and a display part for displaying that the call-waiting is present along with the time information. CONSTITUTION: A control part 14 transmits changeover control signals to switching circuits 15 and 18 and prevents communication data transmitted and received between the control part 14 and a MODEM 12 from being passed through a DSP 19. Thus, the data transmitted from the control part 14 are transmitted from the switching circuit 18 through the switching circuit 15 to the MODEM 12. Also, the communication data transmitted from an opposite side are received in the MODEM 12 by an NCU 13 and transmitted through the switching circuits 15 and 18 to the control part 14.  Then, when the interruption signals of the call-waiting are inputted, the control part 14 lets the communication data received and demodulated in the MODEM 12 be passed through the DSP 19 by the changeover control signals to the switching circuits 15 and 18 and eliminates the call-waiting interruption signals from reception data.

Title: Correction circuit of distortion
Inventor: HENRII EI BURAUBERUTO
IPC: H01L33/00
Filed: 1990-09-07
Abstract: PURPOSE: To make it possible to transmit only a linear part of a source signal by synthesizing distortion inherent in a non-linear device and signals having equal amplitude but opposite signs, so that the inherent distortion of the device is offset by the opposite distortion of the synthetic signal of inherent distortion of the device. CONSTITUTION: In order to reduce distortion due to the trnasmission of an analog signal, an input modulation signal is divided into primary and secodary passes 13, 14. A reverse distortion amplifier 15 formed n the secondary pass 14 forms the secodary or more mutual modulation distortion product of the input signal. The formed reverse distortion is controlled so as to have equal distortion and amplitude inherent in the non-linear modulation device to which the signal is inputted and have a reverse code. The phases of signals are synchronized by a delay or phase control element 23 formed on one of the passes 13, 14 and a single modulation signal including mutual modulation product distortion is formed by recombining the signals from the passes 13, 14. Thus, the inherent distortion of the non-linear trnasmission device is offset.  Consequently, the transmission of the modulation signal can be effectively linearized.

A butterfly valve 90 is controlled to open wide when the sensed level is higher than a reference pressure level otherwise open slightly. Consequently, the discharge rate is regulated through the discharge tube 70 and the inner pressure is sustained at a constant level.
