  • Patent number: 11986878
    Abstract: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).

  • Patent number: 11486828
    Abstract: A fluorescence photometer includes a photometer unit and an optical fiber unit. The photometer unit includes a light source, an excitation-side spectroscope for separating light emitted from the light source to generate excitation light, and a fluorescence-side spectroscope for separating fluorescent light emitted from a sample irradiated with the excitation light to generate monochromatic light. The optical fiber unit guides the excitation light to the sample placed outside the photometer unit and guides the fluorescent light emitted from the sample to the photometer unit and includes an image fiber for capturing an image of the sample, an excitation-side fiber arranged around the image fiber and for guiding the excitation light to the sample, and a fluorescence-side fiber arranged around the image fiber and to guide the fluorescent light emitted from the sample to the photometer unit. The excitation-side fiber and the fluorescence-side fiber are arranged to surround the image fiber.

  • Patent number: 8584742
    Abstract: A heat exchanger having excellent heat exchanging performance is obtainable by a simple production technique and at a low cost. This is achieved by providing a fin member and by increasing heat conductivity between the fin member and a meandering pipe body. Further, the heat exchanger is made compact for high degrees of layout freedom, enabling the heat exchanger to be installed in a tight space. Engagement grooves (8) are provided in both end surfaces (6, 7), which are opposite to each other, of a fin member (5) in which fins (4) are parallel arranged. Straight pipe sections (2) are parallelly arranged, with gaps (16)in between, in the engagement grooves (8) of the fin member (5). The straight pipe sections (2)a are connected at bent sections (3). A pair of meandering sections (11, 12) is arranged opposite to each other with an insertion gap (17) of the fin member (5) in between.

  • Publication number: 20130201477
    Abstract: Provided herein is an elementary analysis apparatus allowing size and weight reduction and capable of performing atomic adsorption spectrometry by an electrothermal method and of forming plasma without using a gas. A sample is supplied from a liquid feed portion through a flow channel to an atomizing portion, and a voltage is applied between electrodes. When the voltage is applied to the electrodes, electric current and electric field are concentrated in the atomizing portion and bubbles are generated to cause a plasma in the bubbles, and element in the sample is atomized by the plasma. Light that irradiates the atomizing portion from a light source and is transmitted therethrough is received, for example, by an optical fiber or the like and split by a spectrophotometer. The amount of the split light is detected by a detector and analyzed by a computer.

  • Publication number: 20070164951
    Abstract: A driving circuit of a liquid crystal panel is provided to a glass substrate. A power supply IC for supplying power to the driving circuit is mounted on FPC for electrically connecting the liquid crystal panel and an image output IC at the outside of the liquid crystal panel. The liquid crystal panel can be driven by the driving circuit on the glass substrate without use of a relatively expensive driver IC for driving the liquid crystal panel, and thus the manufacturing cost can be suppressed. By providing the power supply IC on FPC, the precision of the power supply IC can be enhanced, and the display quality of the liquid crystal panel can be secured.

  • Patent number: 5656901
    Abstract: A reaction force generating apparatus is provided which generates a reaction force for a rotationally operated member to be manually or mechanically operated. An alternating motor is provided that has a stator with three-phase coils; a rotor including permanent magnets; and a rotational axle extending from the center of the rotor and having a rotationally operated member attached to its one end. A direct voltage is supplied to the three-phase coils of the alternating motor, thereby producing a magnetic field on the stator. The magnetic field is oriented in one direction and cooperates with the permanent magnets to generate an electromagnetic attraction force for maintaining the operated member in a predetermined angular position. When the operated member is moved, a torque, or reaction force, is generated to restore the initial position of the operated member.
