Patent number: 7370436Abstract: An apparatus capable of performing consecutively, independently and/or simultaneously the processes of quick freezing and/or freeze drying of produce. The apparatus is characterized by a central vacuum system operating over one or more independent vacuum chambers (10,11,12,13,14); said vacuum system being composed of at least two vacuum subsystems (40,50), connected to the chambers by means of independent manifolds (400,500). One vacuum subsystem (40) evacuates air from any of the chambers from atmospheric pressure to a pressure slightly above that of the triple point of water, and the other vacuum subsystem (50) further quickly evacuates any of the chambers from said pressure slightly above the triple point of water to the pressure corresponding to the thermodynamic equilibrium of ice and water vapor at a desired freezing temperature, in a desired freezing time.Type: GrantFiled: July 9, 2001Date of Patent: May 13, 2008Inventors: Ricardo Francisco Auer, Julian Diego Roberts, Michael Louis McGee, Mitsuru Masuda

Patent number: 7098423Abstract: There is provided a printed board machining apparatus having fewer restrictions in terms of the length of printed boards to be machined, that can be readily controlled in positioning a sheet-like workpiece and that is capable of improving the machining efficiency. Plural sets of optical scanners and f? lenses that compose laser condensing and positioning mechanisms are disposed apart in a width direction (X direction) orthogonal to a longitudinal direction (Y direction) of the sheet-like workpiece and two sheet-like workpieces are fixed on a machining table in parallel, and in the width direction to machine printed boards on the sheet-like workpieces The disposition of the f? lenses allows the machining of the plurality of lengthy printed boards to be completed practically at the same time or at the same time without limiting the length of the printed boards to be machined.Type: GrantFiled: May 31, 2005Date of Patent: August 29, 2006Assignee: Hitachi Via Mechanics, Ltd.Inventors: Mitsuru Masuda, Kaoru Matsumura

Patent number: 5666386Abstract: In a digital data demodulating apparatus, total number of low-pass filters is reduced by supplying variable sampling clock signals to A/D converters coupled to the low-pass filters. The digital data demodulating apparatus for receiving/demodulating a transmission signal that is modulated by digital data in a predetermined modulation manner, includes: a detecting unit for detecting the transmission signal; a low-frequency component passing unit for causing a low-frequency component of the transmission signal detected by the detecting unit to selectively pass therethrough; an analog-to-digital (A/D) converting unit for A/D-converting the output from the low-frequency component passing unit into a digital transmission signal; a demodulating unit for demodulating the digital transmission signal from the A/D converting unit; and a switching unit for switching a frequency of a sampling clock produced from the A/D converting unit in response to an external switching instruction.Type: GrantFiled: October 11, 1996Date of Patent: September 9, 1997Assignee: NEC CorporationInventor: Mitsuru Masuda

Patent number: 4164683Abstract: The fluorescent display tube is of the flat tube type driven by a dynamic drive system. The tube comprises a transparent envelope made up of a flat substrate and a cover spaced therefrom. A first display unit is formed on the inner surface of the substrate while a second display unit is formed on the inner surface of the cover. Each of the first and second display units comprises electrodes arranged in a pattern to be displayed and phosphor films coated on the electrodes. The electrodes of the second display unit are made of transparent material. Where the electrodes of respective display units are selectively energized the phosphor films on the selected electrodes are caused to fluoresce by thermal electrons generated by a cathode electrode thus displaying a desired pattern.Type: GrantFiled: June 21, 1978Date of Patent: August 14, 1979Assignees: ISE Electronics Corporation, Fujitsu Ten LimitedInventors: Tadashi Nakamura, Mitsuru Masuda, Hiroshi Tanaka
