PROBLEM TO BE SOLVED: To increase impact strength of a cover fit to the opening of a covering material in a battery pack in which a battery element is housed in the covering material. SOLUTION: The battery element is housed in the hard covering material 1 having a first opening and a second opening at both ends, and a first cover and a second cover manufactured by resin molding are fitted to the first opening and the second opening. The second cover 3 has one or two or more through holes 32 filling resin between the second cover 3 and the battery element, and a groove 33 installed on the surface facing the battery element. When resin is filled between the second cover 3 and the battery element through the through hole, resin is filled in the groove installed on the surface facing the battery element and cured. It is therefore possible to ensure anchor effect. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To prevent dislocation between electrodes, for improved assembling precision, by raising rigidity of an index pin to cope with the difference of loads due to bead glass pressurization. SOLUTION: Related to the method for manufacturing an electron gun, a beading process is provided in which first-third electrodes G 1 , G 2 , G 3 A, G 3 B are arrayed through a spacer by aligning with an index pin while fourth-sixth electrodes G 4 , G 5 , G 6 A, G 6 B are arrayed and held, in parallel, with a specified interval, with plate-like insulators 2 and 3 disposed on the side opposed to the array. The insulator is softened by heating and then pressurized so that a part of each electrode is supported by the insulator. The first electrode aligned with the index pin is divided into a first structure 20 of a main component part and a holder 21 for fitting the first structure. The first structure fitting holder is arrayed through the spacer for aligning the holder. The holder aligning spacer is provided with a relatively large index hole. A part of the index pin is formed, for alignment, at a large diameter part to correspond to the size of index hole. COPYRIGHT: (C)2003,JPO

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk device where a highly precise and exact tracking retraction is enabled. SOLUTION: A DIR signal generating part 8 generates a discriminating signal for discriminating the driving direction of a tracking actuator 3 which moves an incident laser beam on an optical disk 1 in a direction traversing a track in a manner of raising time resolution for directional detection based on a polarity of a mate signal in respective rising and falling positions of a tracking zero cross signal Ftzc and a mirror signal Fm. Only the decelerating polarity part of the tracking actuator 3 of a tracking driving signal Ftf from a tracking phase compensating filter 10 is outputted as a brake signal Fb1 by a brake signal generating part 11 in accordance with the judging direction. Thus, the highly precise tracking retraction becomes possible in accordance with the driving direction of the tracking actuator 3 exactly, and the operation of the stable tracking retraction is exactly and quickly performed by an effective braking operation.
Abstract:
PROBLEM TO BE SOLVED: To secure compatibility for plural kinds of optical recording media with different later constitution, to miniaturize a device itself and to realize reproduction of an information signal with high reliability by sharing a part with plural optical paths. SOLUTION: Light source 3a, 4a emit laser light with different wavelengths answering to plural kinds of optical disks with different layer constitution. Objective lenses 5a, 5b converge the laser light outgoing from the light source 3a, 4a on a recording layer of a preserved optical disk. An objective lens switch mechanism 20 switches the objective lens 5 to a recording/reproducing position and move it. A spectroscopic means light divides the incident light outgoing from the prescribed light sources 3a, 4a and the reflection laser light reflected by the optical disk. The photodetectors 4b, 6 receives the reflection laser light light divided by the spectroscopic means. Then, an optical system correction means corrects the prescribed objective lens 5.

PURPOSE:To improve the S/N and to realize the stable tracking servo or focusing servo. CONSTITUTION:One piece of light beam is divided into three pieces in the horizontal direction by a diffraction grating, and moreover, divided into three pieces in the vertical direction by a Wollaston prism, and total nine pieces of light beams are generated. A photodetector 22 is arrayed so that all of these nine pieces of light beams L1, L2, L3, L1L, L2L, L3L, L1R, L2R and L3R can be detected. Outputs of each area A to H of the photodetector 22 are calculated by an arithmetic circuit 31, and a focus error signal Sf, a tracking error signal St, and a signal Si corresponding to recording information are generated, respectively.
Abstract:
PROBLEM TO BE SOLVED: To suppress or reduce the resonance of a mechanical element generated in an electromechanical element provided with a mechanical element having a mechanical resonance frequency element due to an external electric drive signal by cutting off or reducing the a resonance frequency element in the electric signal before introduced into the electromechanical element. SOLUTION: The electromechanical device and the electromechanical optical modulation device are composed by having: the electromechanical element 2 provided with the mechanical element having the mechanical resonance frequency element; a signal source 3 of the electric drive signal which drives the electromechanical element 2; and a means which cuts off or reduces the resonance frequency element in the electric drive signal supplied from the signal source 3. The resonance of the mechanical element due to the electric drive signal is suppressed or reduced by taking the composition. Further, in the image display device having the electromechanical optical modulation device, the restriction of improving the image quality is mitigated. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To improve and stabilize the working accuracy of the dimension and shape, the positioning accuracy, and the dimensional evaluation by forming a recessed part of V-shaped section having an opening narrower than a bottom part of the recessed part through the coining. SOLUTION: A base metal 31 of thickness t11 is coined by a coining punch 32 until the thickness t12 is obtained to form a recessed part 34 having an opening 33. The finish coining is effected using a finish coiling punch 39 comprising a punch body 37 to regulate the width and the shape of an opening member 33a and a projection-like part 38 for material shifting which is integratedly provided on the outside of the punch body 37. When the projection-like part 38 presses an upper surface of the base metal 31, a large stress is exerted inwardly and downwardly to generate the plastic deformation, a recessed part 41 is formed, the metal is shifted, the opening member 33a is pressed against the punch body 37 and regulated. The opening member 33a is formed in the shape same as a curved shape of a root part of the punch body 37, and the recessed part 34 is of V-shaped section in which the opening member is narrower than a bottom part. A through hole 43 is formed therein.
