Patent number: 10274713Abstract: A microscope includes a stage on which a specimen is configured to be placed, an epi-illumination optical system having a fluorescence illumination light source configured to irradiate the specimen with excitation light of a predetermined wavelength, a transmitted-light illumination optical system, and a light shielding member. The transmitted-light illumination optical system includes a transmitted-light illumination light source having a white LED, and a condenser having a condenser lens configured to collect light emitted from the transmitted-light illumination light source onto the specimen and configured to move in a direction orthogonal to an illumination optical path so as to be insertable onto and removable from the illumination optical path.Type: GrantFiled: August 9, 2017Date of Patent: April 30, 2019Assignee: OLYMPUS CORPORATIONInventors: Shintaro Kobayashi, Hironori Utsugi, Minoru Hanaoka

Patent number: 9834706Abstract: A pressure-sensitive adhesive tape that uses, as a plasticizer, an alternative compound to bis(2-ethylhexyl) phthalate (DOP) and dibutyl phthalate (DBP), having excellent tackiness, and can be unwound satisfactorily, where DOP and DBP are to be restricted under the REACH regulation. The pressure-sensitive adhesive tape includes a poly(vinyl chloride) substrate and a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is disposed on or over one side of the substrate. The poly(vinyl chloride) substrate contains 10 to 40 percent by weight of bis(2-ethylhexyl) terephthalate. The pressure-sensitive adhesive tape preferably has an unwinding force of 0.4 N/20 mm or less at a tensile speed of 0.3 m/min and an unwinding force of 1.2 N/20 mm or less at a tensile speed of 30 m/min.Type: GrantFiled: February 24, 2015Date of Patent: December 5, 2017Assignee: NITTO DENKO CORPORATIONInventors: Takumi Yutou, Minoru Hanaoka

Publication number: 20160107425Abstract: The present invention provides pressure-sensitive adhesive films with a favourable visual appearance and surface printability without discoloration and burrs on the cutting edge after short-wavelength laser machining. At the same time, the PSA films of the present invention exhibit a favourable cuttability, allowing for high fiber laser as well as carbon dioxide laser cutting speeds. Since the use of the PSA films of the present invention as surface protecting films does not require extensive cleaning and polishing operations after the cutting process and the cutting process itself may be accelerated, the efficiency of laser machining methods may be improved.Type: ApplicationFiled: October 20, 2015Publication date: April 21, 2016Applicants: Nitto Europe N.V., NITTO DENKO CORPORATIONInventors: Bart FORIER, Donald PINXTEN, Minoru HANAOKA

Patent number: 5339304Abstract: An optical disc has a two-step pit structure in which first pits and second pits whose depth is a half of that of the first pits are arranged in superposition in the same track direction. A first laser diode emits first laser light having a first wavelength which is four times the depth of the first pits, and a second laser diode emits second laser light having a second wavelength which is four times the depth of the second pits. An optical system introduces the first and second laser light onto a recording surface of the optical disc, and also introduces reflected light to a detector. A selecting drive mechanism may be provided to select one of the first and second laser diodes as a light source for actually emitting light to be introduced onto the recording surface.Type: GrantFiled: April 8, 1993Date of Patent: August 16, 1994Assignee: Pioneer Electronic CorporationInventor: Minoru Hanaoka
