Publication number: 20040131077Abstract: All port numbers are set at a server, whereas only one port number is set at a client. The client searches for the server by using the set port number. The server responds to searching by the client and notifies the client of the other port number that is not set at the client. The client establishes the communication with the server by using the notified port number. This makes it unnecessary to set all port numbers at the client. It is therefore possible to provide a server client system with time for setting a port number decreased.Type: ApplicationFiled: October 10, 2003Publication date: July 8, 2004Applicant: ONKYO CORPORATIONInventors: Susumu Takemura, Yasushi Ikeda, Koichi Kato

Publication number: 20030028995Abstract: The present invention relates to a novel and highly effective design for the squeegee blades used to remove and collect used cleaning solution and other liquids from substantially flat surfaces in manual and motorized cleaning tools. In comparison to the prior art, the present invention provides the squeegee blade with controlled flexibility so that the blade contacts the surface to be cleaned with a wiping lip area that does not change with the applied pressure. As a result of the constant wiping area provided by this invention, the new squeegee blades can operate efficiently on uneven surfaces with reduced wear. Further, the constant contact area between squeegee blade and the surface to be cleaned provides an excellent sealing action, which in turn, leads to more effective removal of the used cleaning solution from the surface and minimizes losses in vacuum that removes the liquid.Type: ApplicationFiled: July 5, 2001Publication date: February 13, 2003Inventor: Yasushi Ikeda

Patent number: 5117106Abstract: A scanning pattern drawing apparatus which scans the surface of a workpiece with a light beam so that a pattern is described on the workpiece with the issued light beam being controlled on the basis of pattern drawing data stored in a pattern memory, wherein the pattern drawing apparatus is able to read many pieces of data in a short period of time even if the frequency of the timing pulses is reduced and which therefore is capable of drawing a precise pattern on a workpiece. A scanning pulse generator produces as scanning pulse in response to a predetermined amount of scanning with the light beam. The scanning pulse is converted to a plurality of resulting timing pulses, and successive parallel outputs of the timing pulses are produced after delaying by a predetermined time. The pattern drawing data is read from the pattern memory in response to the delayed timing pulses.Type: GrantFiled: June 23, 1991Date of Patent: May 26, 1992Assignee: Asahi Kogaku Kogyo K.K.Inventors: Hiroaki Andon, Michio Ohshima, Yuji Matsui, Takashi Okuyama, Toshitaka Yoshimura, Hidetaka Yamaguchi, Yasushi Ikeda, Jun Nonoka, Tamihiro Miyoshi, Mitsuo Kakimoto, Masatoshi Iwama, Hideyuki Morita, Satoru Tachihara, Akira Morimoto, Akira Ohwaki

Patent number: 5093561Abstract: A drawing surface adjusting mechanism suitable for use with a large scanning pattern drawing apparatus in which a scanning optical system scans drawing rays of light along scanning lines on a workpiece on a drawing board. A plurality of light-emitting units project rays of light in a wavelength region outside a sensitivity range of the workpiece onto a drawing surface of the workpiece in such a way that the rays substantially converge at more than one point along a scanning line of the drawing rays of light, preferably at center and end points along the scanning line. A plurality of condenser lenses are provided for focusing beams of light from the plural light-emitting units after the beams have been reflected by the drawing surface. A plurality of light-detecting elements are disposed at points of condensation by respective ones of the condenser lenses to produce output signals representing differences in condensation points that occur as the lenses depart from or approach the drawing surface.Type: GrantFiled: July 18, 1991Date of Patent: March 3, 1992Assignee: Asahi Kogaku Kogyo K.K.Inventors: Hiroaki Andoh, Michio Ohshima, Yuji Matsui, Takashi Okuyama, Toshitaka Yoshimura, Hidetaka Yamaguchi, Yasushi Ikeda, Jun Nonaka, Tamihiro Miyoshi, Mitsuo Kakimoto, Masatoshi Iwama, Hideyuki Morita, Satoru Tachihara, Akira Morimoto, Akira Ohwaki

Patent number: 5046796Abstract: An apparatus for correcting a scranning beam produced by a polygonal mirror tilting in small surface segments in each mirror surface segment caused by uneven mirror surfaces of the polygonal mirror. Data indicative of the amount of tilting in each of the surface segments is stored in a memory, which is addressed by a data signal indicative of the present scanning position of the polygonal mirror. Output data from the memory is applied to an acousto-optical modulator disposed in the beam path between the light source and the polygonal mirror.Type: GrantFiled: December 1, 1989Date of Patent: September 10, 1991Assignee: Asahi Kogaku Kogyo K.K.Inventors: Hiroaki Andoh, Michio Ohshima, Yuji Matsui, Takashi Okuyama, Toshitaka Yoshimura, Hidetaka Yamaguchi, Yasushi Ikeda, Jun Nonaka, Tamihiro Miyoshi, Mitsuo Kakimoto, Masatoshi Iwama, Hideyuki Morita, Satoru Tachihara, Akira Morimoto, Akira Ohwaki

Patent number: 5043566Abstract: A monitor mechanism for use with a scanning optical apparatus in which the direction of polarization is utilized to separate a source laser light beam into a pattern drawing and a monitor beamlet and to synthesize them again into a single after passing through a scanning lens and beam deflector. The two beamlets can thus be controlled so as to project towards the deflector and scanning lens in the same direction, which is effective in reducing the offset between the pattern drawing and monitor beams that may occur on account of such factors as variations in lens performance.Type: GrantFiled: December 1, 1989Date of Patent: August 27, 1991Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hiroaki Andoh, Michio Ohshima, Yuji Matsui, Takashi Okuyama, Toshitaka Yoshimura, Hidetaka Yamaguchi, Yasushi Ikeda, Jun Nonaka, Tamihiro Miyoshi, Mitsuo Kakimoto, Masatoshi Iwama, Hideyuki Morita, Satoru Tachihara, Akira Morimoto, Akira Ohwaki
