  • Publication number: 20190136171
    Abstract: A well has a pair of side surfaces, and one of the side surfaces is in contact with a compartment of a first channel with a gas-permeable membrane being interposed therebetween and the other side surface is in contact with a compartment of a second channel with a gas-permeable membrane being interposed therebetween. The well is filled with a liquid cell culture medium, and in such a state, a high-concentration gas and a low-concentration gas, which are different in the concentration of a specific component from each other, are allowed to flow through the first and second channels, respectively, to form a concentration distribution of the specific component in the well.

  • Patent number: 8414782
    Abstract: A process for producing a fluorocarbon microstructure capable of easily fabricating a three-dimensional fluorocarbon microstructure. The process for producing a fluorocarbon microstructure comprises a first processing step for forming, on a substrate (2), a film deposition portion with a given pattern made up of a through-hole figure by etching the substrate (2), a fabricating step for forming a fluorocarbon film (6) on an inner circumferential surface of a film deposition portion (9) to fabricate a fluorocarbon region surrounded by the fluorocarbon film (6), and a second processing step for fabricating the fluorocarbon microstructure protruding from a processing surface of the substrate (2) by etching a given region other than a fluorocarbon region on the substrate (2). Hence, the three-dimensional fluorocarbon microstructure can be fabricated which comprises a complicated structure that has conventionally been hard to fabricate.

  • Publication number: 20110195277
    Abstract: A high density magnetic recording medium including aggregates of magnetic nanoparticles arranged stably and efficiently in demarcated sections in the surface of a substrate is manufactured by the steps of forming a plurality of parallel tracks in the surface of the substrate, forming a plurality of minute recesses serially at approximately equal intervals in each of the tracks, casting a liquid dispersion of magnetic nanoparticles into the minute recesses, and evaporating dispersing medium from the liquid dispersion, thereby forming an aggregate of magnetic nanoparticles in each of the minute recesses.

  • Publication number: 20090218313
    Abstract: There is provided a method for manufacturing a patterned magnetic recording medium including a step of completely removing an etching resist on a magnetic layer 3, which is used for etching the magnetic layer 3, without deteriorating magnetic characteristics of the magnetic layer 3. The step of removing the etching resist used for etching the magnetic layer 3 includes the steps of irradiating the etching resist on the magnetic layer 3 or the first protective layer 4 with an excimer VUV laser under a reduced pressure and immersing the resist coating 5 remaining on the magnetic layer 3 or the first protective layer 4 into a resist removing agent solution to wash off the resist coating 5.

  • Publication number: 20060021666
    Abstract: A micro system capable of setting an appropriate amount of stimulation being applied in order to control liquid flow in a channel. The micro system comprises micro-heaters (5b, 5c) for applying stimulation to liquid flowing through liquid channels (2b, 2c) formed in a plate (1) and controlling liquid flow by the stimulation from the micro-heaters (5b, 5c), and a means for electrically controlling the amount of stimulation being applied to the liquid from the micro-heaters (5b, 5c). An appropriate amount of stimulation can be set by electrically controlling the amount of stimulation being applied to the liquid from the micro-heaters (5b, 5c) through the control means.

  • Patent number: 6122358
    Abstract: A terminal management unit for executing control for connection to an operator when a communication apparatus is busy is provided in a network, and terminals connected to the network are registered as operator terminals in a master list possessed by the terminal management unit If the communication apparatus is busy when an incoming call from a caller arrives at the communication apparatus, the terminal management unit stores the telephone number of the caller in a registration list on the originating side. The terminal management unit subsequently refers to the master list, periodically calls the operator terminals and, when an operator terminal responds, calls the caller, which has been registered in the registration list on the originating side, and connects the caller to this operator terminal.

  • Patent number: 5539814
    Abstract: When a subscriber A provided with a call-waiting service and connected to a subscriber B is called by another subscriber C and when the subscriber A responds to a call-waiting tone, the subscriber A is connected to the subscriber C and the subscriber B is held according to a procedure of the call-waiting service. If the subscriber B replaces the handset, a clearing intrusion tone (CIT) is sent to the subscriber A before changing a three-way connection to a connection between the subscriber A and the subscriber C, and the subscriber A notices that the held subscriber B is disconnected before attempting to communicate with the subscriber B and without having to rely on a busy signal.

  • Patent number: 5402005
    Abstract: At least one slit having a predetermined shape is formed around a contact region of a lower wiring layer formed on a substrate, and an insulating portion formed integrally with an insulating layer is embedded in this slit. This insulating layer is formed on the lower wiring layer and has a contact hole located at a position corresponding to the contact region. Since the insulating portion as a rectangular projecting portion projects into the slit downwardly from the rigid insulating layer, positional errors caused by thermal expansion of the lower wiring layer in annealing of the upper wiring layer can be suppressed, and an abnormal geometry such as a projection on the upper wiring layer can be prevented. In addition, a semiconductor device free from interwiring short-circuiting and excellent in flatness can be obtained.
