Patent number: 6991217Abstract: In an oscillation type linear actuator for reciprocally moving a plurality of moving members held in parallel with each other in a predetermined direction owing to electromagnetic action between a stator and them, two moving members reciprocally moving in opposite phases with each other are coupled by a coupling member having spring function, and a non-displacing portion of a plate spring portion of the coupling member which is not displaced substantially is restricted by a stopper. Even when an external force is applied to one of two moving members reciprocally moving in the opposite phases each other, motion of the other moving member is transmitted to the moving member via the coupling member, so that reduction of amplitude of the moving member to which the external force is applied can be restricted, and a balance of amplitudes of two moving members is maintained.Type: GrantFiled: June 17, 2003Date of Patent: January 31, 2006Assignee: Matsushita Electric Works, Ltd.Inventors: Hiroaki Shimizu, Hidekazu Yabuuchi, Masashi Moriguchi, Noboru Kobayashi, Ryo Motohashi, Ryuji Otani

Publication number: 20050134123Abstract: A linear oscillating actuator system which is capable of canceling out the stator vibrations for driving a load with a minimum of vibrations. The system includes an oscillator carrying a permanent magnet as well as an output shaft for connection to the load. A stator assembly is incorporated within a housing and is configured to movably support the oscillator and to carry an electromagnet. The electromagnet generates a magnetic field which interacts with the permanent magnet to reciprocate the oscillator relative to the stator assembly in a linear path. A balancer is added to the system for canceling out undesired stator vibrations. The balancer are commonly supported to the stator assembly to be driven thereby in parallel with the oscillator. The balancer is configured to have a mass generally equal to that of the oscillator and to be devoid of any output member.Type: ApplicationFiled: December 17, 2004Publication date: June 23, 2005Inventors: Noboru Kobayashi, Masashi Moriguchi, Takahiro Nishinaka, Hidekazu Yabuuchi, Ryo Motohashi

Publication number: 20030094861Abstract: An improved linear oscillating actuator is capable of minimizing the undesired vibrations while moving first and second oscillators in parallel paths. The first and second oscillators carry first and second drive elements respectively for driving connection to individual reciprocating loads. The first and second drive elements project upwardly respectively from the first and second oscillators such that the first drive element is disposed immediately upwardly of the second oscillator and the second drive elements is disposed immediately upwardly of the first oscillator. With this reverse arrangement of the first and second drive elements relative to the first and second oscillators, the individual oscillating systems each including the oscillator, the drive element and the corresponding reciprocating load can have its mass center disposed in close proximity to a mass center of the actuator, thereby enabling to reduce undesired vibrations which would otherwise occur around the mass center of the actuator.Type: ApplicationFiled: June 7, 2001Publication date: May 22, 2003Applicant: Matsushita Electric Works, Ltd.Inventors: Hiroaki Shimizu, Ryo Motohashi, Hidekazu Yabuuchi, Takahiro Nishinaka, Noboru Kobayashi

Patent number: 6422168Abstract: A watercraft incorporates a vertically elongated displacement hull section to elevate the riders of the watercraft well above the water level when the watercraft is up on plane. During normal low-speed displacement hull-type operation, the elongated displacement hull section remains submerged, and does not appreciably affect the stability of the watercraft. When the watercraft is accelerated to planing speed, however, the elongated displacement hull section rises out of the water, and the watercraft planes on the planing surface disposed at the bottom of the elongated displacement hull section. In this manner, the operator/riders are lifted a significant distance above the surface of the water. The watercraft further incorporates an elongated displacement hull section having a bulged section which is sized to accommodate the watercraft engine within the elongated displacement hull section.Type: GrantFiled: June 26, 2000Date of Patent: July 23, 2002Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Noboru Kobayashi

Publication number: 20010055310Abstract: A signal processing apparatus for assigning channels to a plurality of DSP's to be used comprises a control circuit for controlling the DSP's, a library for storing a plurality of signal processing algorithms, and a channel assignment table. The control circuit, when an assignment designation of a channel and an algorithm for each of the DSP's is received, compares the designated algorithm with the algorithms having been already downloaded to the DSP's based on the table, thereby downloading only an algorithm required to be newly downloaded from the library to the DSP's or between the DSP's and assigning the downloaded algorithm to the received channel. The channel assignment table can fixedly/variably store a relationship between processing positions (time slots) in addition to the relationship between the channels and the DSP's.Type: ApplicationFiled: August 6, 2001Publication date: December 27, 2001Inventors: Noboru Kobayashi, Naoji Fujino, Hideaki Kurihara, Mitsuru Tsuboi, Teruyuki Sato, Fumiaki Nishida

Publication number: 20010034601Abstract: On the basis of parameters representing background noise characteristics and parameters representing voice characteristics of a current frame, a voice activity detector 42 identifies whether the current frame is a non-active voice segment of background noise only or an active voice segment in which background noise has been superimposed on voice. The voice activity detector updates the background-noise characteristic parameters in each frame, irrespective of whether requirements for updating the background-noise characteristic parameters have been satisfied, in an interval of time from start of a steady operation for detection of voice activity to identification of an active voice segment. Further, the voice activity detector 42 relaxes the update requirements of the background-noise characteristic parameters based upon results of voice activity and voice non-activity detection and, when these requirements have been satisfied, updates the background-noise characteristic parameters.Type: ApplicationFiled: May 17, 2001Publication date: October 25, 2001Inventors: Kaoru Chujo, Toshiaki Nobumoto, Mitsuru Tsuboi, Naoji Fujino, Noboru Kobayashi

Patent number: 6084716Abstract: A single light emitted from a laser source is split into multiple beams. The multiple beams are illuminated by a multi-beam scanner to scan a substrate of interest. An optical system is provided for focusing the multiple beams independently on the substrate and directing a reflected light or a transmitted light of the multiple beams on the substrate. Aperture regulating members are disposed at equal intervals corresponding to the interval between the multiple beams for controlling the multiple beams directed from the substrate by the optical system. The multiple beams passed through their respective aperture regulating members are received by an optical detector assembly which detect a change in the amount of the multiple beams. The substrate is continuously moved by a movable table on a plane substantially vertical to the multiple beams and in a direction arranged at substantially a right angle to the scanning direction of the multiple beams.Type: GrantFiled: July 9, 1998Date of Patent: July 4, 2000Assignees: Kabushiki Kaisha Toshiba, Topcon CorporationInventors: Yasushi Sanada, Toru Tojo, Mitsuo Tabata, Kyoji Yamashita, Hideo Nagai, Noboru Kobayashi, Hisakazu Yoshino, Makoto Taya, Akemi Miwa
