Inventor: IMAI HIROSHI
IPC: H04N19/85
Filed: 1992-04-07
Abstract: PURPOSE:To reduce the picture deterioration of the moving picture due to transmission errors. CONSTITUTION:At a variable length encoder 105, a unit to gather code words is not defined as the big unit such as GOB and one frame or the like and is defined as the minimum block. Also, at an error detecting / code adding circuit 107, codes which can be detected even when the transmission error happens are added to respective blocks so that the moving picture decoding device can accurately perform the segmenting of blocks, and the propagation of error decoding can be suppressed inside the minimum block. Also, the deterioration of picture can be suppressed by providing an error detecting circuit 109 and motion vector predictor 114, predicting the motion vector from the motion vector of the block adjacent to the block for the block where the error exists, and using the data of the previous frame extracted by the motion vector.

Title: Antireflection film and display device arranging it
Inventor: SOTOZONO HIROHISA
IPC: G02B1/11
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To provide an antireflection film with sufficient film strength while leaving cavities among particles by forming a layer containing core shell structured particles with the average size being a specified value or less and making the glass transition temperature of shell polymer of the particles lower than that to core polymer. SOLUTION: An antireflection film has a layer containing core shell structured particles with the average size being 200 nm or less, the glass temperature of shell polymer of the particles being lower than the glass transition temperature of core polymer and the layer being formed as a low-refraction-factor layer. It is not desirable that frontward scattering is increased if the particle size is increased and scattered light is colored if it exceeds 200 nm. More preferably, it is 70 nm or less from the point of optical performance and film quality, especially 50 nm or less. If the shell polymer in the core shell particles is deformed at a filming temperature, microvoids are decreased and so cavities in the layer are preferably 3 vol% or more and 50 vol% or less, especially 5 vol% or more and 35 vol% or less.

IPC: H01F41/12
Filed: 1978-07-12
Abstract: PURPOSE: To prevent insulation breakage of corner section of a rectangular-shape electromagnetic coil and form the electromagnetic coil into a given shape by turning an original coil, cylindrically coiled wire consisting of self-brazing type electric wire, into a required shape by using pressing and heating processes.  
     CONSTITUTION: A self-brazing type coiled wire is cylindrically wound to form a cylindrical coil 5, and thus formed coil 5 is turned into a rectangular-shape electromagnetic coil 9 by applying pressure on it using internal forming jigs 8 and 8'. And then, it is sent into a drying furnace to be heated so that it can be formed into a solid body of a required shape. As the original coil is formed into a cylindrical shape, it is possible to prevent an insulation film of a corner section from being damaged. It is also possible to pass the coil, prior to being wound, in a solvent tank 10 to allow solvent 17 to adhere onto the coil so that it can be wound while undergoing thermal hardening. By employing this method, it is possible to prevent insulation breakage of corner section of a rectangular electromagnetic coil and, at the same time, to form it into any given shape.

Title: Magnetic-field detector for electronic watch
Inventor: UEDA MAKOTO
IPC: G04C3/14
Filed: 1978-07-14
Abstract: PURPOSE:To detect easily and definitely a voltage induced across the coil of a motor by an external magnetic field, by the alternate-connection time of a high resistance and low resistance to more than 20msec in a detector which detects the voltage by alternately connecting the high resistance and low resistance to the coil of the motor. CONSTITUTION:A voltage induced across the coil of motor 20 by an external magnetic field is shorted by the closed loop of N gates 23 and 24. Then, the ON resistances of N gates 23 and 24 are low and the developed voltage across the coil is shorted by ON resistances, so that a relatively-large current will flow. Next, the switching of the closed loop of motor 20, N gates 26 and 23, and detection resistance 29 develops a momentarily-large voltage across detection resistance 29 since the coil of motor 20 has an inductance component and the voltage is stabilized afterward to a steady value determined by detection resistance 29 and the induced voltage. In general, the frequency of an alternating-current magnetic field is a commercial frequency of 50 or 60Hz and its cycle is 20 or 16.7msec. For the purpose, the time for alternate connections, namely, the minimum detection period should be more than 20msec.

Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a polarization separating element whose characteristic such as diffraction efficiency is stable so that it is of a higher quality. SOLUTION: This method for manufacturing a polarization separating element 10 includes the process of forming a polydiacetylene orientation film (double refraction material layer) 12a on a glass substrate 11, a first heat treatment process for causing a change in hue of the double refraction material layer 12a by means of heat or for stabilizing its molecular structure, and a process for forming a periodic grating 12b through patterned exposure to ultraviolet radiation. The method is provided with a second heat treatment process in which, after the periodic grating 12b is formed, it is stabilized by means of heat.  In the second heat treatment process, a heat treatment is performed below a temperature at which change in hue of the periodic grading 12b progresses or contraction of a film due to stabilization of the molecular structure progresses, e.g. at 140 deg.C, with the time of the heat treatment set in accordance with the kind of a light source employed in patterned exposure; a heat treatment is carried out for five to ten hours when a xenon-mercury lamp is used. Thus, the polarization separating element can be manufactured having stable diffraction efficiency and high quality such that peeling will not occur during a dancing process.

Title: Detecting apparatus for power failure
Inventor: FUJIYAMA HITOHIRO
IPC: H02J9/06
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting apparatus by which a power failure is detected quickly and in which a circuit is created at low costs, by a method wherein, instead of a diode, a PNP transistor which plays the role of a diode and of a switch is inserted across a power-supply circuit and a backup capacitor. SOLUTION: Before a power failure is generated, the voltage (the power- supply voltage Vb ) of the emitter of a transistor 15 is higher than the voltage of the power-supply terminal of a microcomputer 7, and the collector of the transistor 15 is grounded via a resistance 13 and a resistance 14. As a result, a current from a power-supply circuit 2 flows to the base and the collector from the emitter of the transistor 15. After that, when the power failure is generated, the power supply voltage Vb becomes lower than the voltage of the power supply terminal of the microcomputer 7, no current flows to the base from the emitter of the transistor 15, and the transistor 15 is cut off. As a result, the collector current of the microcomputer 7 does not flow. The power-failure detecting point Pdown of the microcomputer 7 is set at LOW, and the microcomputer 7 judges the power failure.
