Patent number: 7420310Abstract: Of two bearings supporting a rotor of a circuit-integrated type core-equipped brushless motor, a part of an outer periphery of the bearing, which is disposed at a position near a stator core, is allowed to directly abut on an inner periphery of a hole formed in a center of the stator core, and therefore, reduction in thickness, reduction in diameter, space-saving and enhancement in output power can be realized. The stator core is fixed to the casing by causing projected parts provided at the housing to bite into second notched parts formed inside first notched parts formed at the stator core and crimping them, whereby the problem of a decrease in a winding space accompanying reduction in a diameter of the stator core is solved, and reduction in thickness, reduction in diameter, space-saving and enhancement in output power are achieved.Type: GrantFiled: November 17, 2005Date of Patent: September 2, 2008Assignee: Matsushita Electric Industries, Co., Ltd.Inventors: Koji Kadowaki, Hideo Kimura

Patent number: 6895172Abstract: In a video signal reproducing apparatus, the changing time of a sub-video signal is adjusted, by a time-adjusting circuit, so as to be synchronized with the changing of a frame of a main video signal from the output of an interlace-scan-video-signal converter. And the sub-signal is added to the output of an interlace-scan converter by an adder. The output of the adder is converted into a progressive-scan video signal in synchronism with the boundary of frames of main video signal by the progressive-scan video signal converter. In the reproducing apparatus, even in the case that the sub-video signal is recorded without synchronism with the frames of the main video signal, an irregular frame is not generated even when the sub-video changes. And a single field of the sub-video does not leave or is not visible.Type: GrantFiled: February 7, 2001Date of Patent: May 17, 2005Assignee: Matsushita Electric Industries Co., Ltd.Inventors: Tetsuya Itani, Satoshi Kondo

Patent number: 6886176Abstract: An optical disk drive includes a turntable, a first motor for turntable drive, an optical pickup and a drive mechanism arranged on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse directions to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, then moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously. By reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.Type: GrantFiled: April 29, 2003Date of Patent: April 26, 2005Assignee: Matsushita Electric Industries Co., Ltd.Inventors: Yuji Ariyoshi, Toru Tanaka, Masanao Wakikawa, Kiyoshi Ishioka

Patent number: 5444562Abstract: An optical transmission apparatus has an electro-optic converter device which converts an electrical signal into an intensity-modulated light signal in such a way that the amount of wavelength chirping is less than a given amount. Therefore a first optical fiber transmission path can convey the signal over a long distance with a small amount of waveform distortion. An optical property change device changes an optical property of the light signal sent from the first optical fiber transmission path. Therefore a second optical fiber transmission path can transmit the changed light signal to demanders' opto-electronic converter device while alleviating waveform distortion due to interference of plural light waves. The light signal is reconverted into an electrical signal.Type: GrantFiled: March 1, 1994Date of Patent: August 22, 1995Assignee: Matsushita Electric Industries Co., Ltd.Inventor: Masaru Fuse
