  • Publication number: 20180019521
    Abstract: A corner reflector includes annular balloons, which, when gas is supplied to the inside, annularly expand, and radio wave reflective films each developed to a plane by the expansion of the annular balloons. The three annular balloons are provided so as to be orthogonal to each other in the expansion. A constraint fabric wound around each annular balloon is provided. The constraint fabric includes an inner peripheral side fabric portion located on the side of a virtual central axis of the annular balloon and extending in the annular direction around the virtual central axis, and an outer peripheral side fabric portion located on the side opposite to the virtual central axis and extending in the annular direction. The elongation degree of the outer peripheral side fabric portion in the annular direction is higher than the elongation degree of the inner peripheral side fabric portion in the annular direction.

  • Patent number: 8593261
    Abstract: RFID tags are attached to tools of a preform head, a bonding head, and a push-up unit, and information related to each tool such as a dimension of a processing-target die is stored into the RFID tags. When a tool is mounted, an operator inputs manufacturing conditions related to the tool. When information related to the tool read from the RFID tag by an RFID reader/writer and the manufacturing conditions related to the tool do not match each other, a message about wrong mounting of the tool is displayed on a monitor. Further, an operation history of the tool is written into the RFID tag by the RFID reader/writer when the production is completed. The operation history is read when the next production is started, and if the values of the operation history exceed predetermined numbers of times, a message is displayed on the monitor.

  • Publication number: 20130235895
    Abstract: A laser light source (100) according to the present invention includes a laser resonator (150) including a fiber (107) containing a laser active medium and a fiber grating (105, 160) coupled to each of two ends of the fiber (107); an pumping laser light source (104) for emitting pump light into the laser resonator (150); a driving current supply circuit (102) for supplying a pulse-like driving current to the pumping laser light source (104); and a wavelength conversion element (101) for converting a wavelength of laser light which is output from the laser resonator. The laser resonator (150) generates laser light including a principal pulse and a plurality of superimposing pulses which are superimposed on the principal pulse, in accordance with incidence of the pump light; and converted light having the wavelength of each of the principal pulse and the superimposing pulses shortened is generated by the wavelength conversion element (101).

  • Patent number: 8029654
    Abstract: An object of the present invention is to provide a complex material in which an ion conduction film is curved and deformed when a potential difference is applied, which is operated at small electric power, has a large deformation amount, quick response performances, large degree of freedom in shape, and is easy in control of deformation, while having strength and durability necessary for practical use and being excellent in an economical aspect. A conductive cloth (preferably having stretchability), which is made conductive through plating of metal on a cloth or metal complex implantation, is joined as an electrode to both surfaces of the ion conduction film (the film in which an ion exchange film or ion liquid is immersed) made of a fluororesin and the like. When the potential difference is applied, the ion conduction film is deformed.

  • Patent number: 7715148
    Abstract: A slider having an improved atmospheric pressure variation characteristic can be provided by ensuring the desired amount of inflow of air flowing to the air bearing surface in a region where it is difficult to ensure the desired air inflow amount, e.g., a region where the slider/disk relative speed is low or a region where the area of the air bearing surface is small by forming a groove configuration surface in a specified shape. In the negative pressure utilization type slider, a groove configuration surface lower in height than an air in flow surface is formed between the disk inner peripheral end and the disk outer peripheral end of the air inflow surface in the air flow incoming end side of a pressure generating surface, separately from a negative pressure generating surface.

  • Patent number: 7187514
    Abstract: The present invention implements a magnetic disk drive usable under a wide range of temperature environment conditions, and a magnetic head assembly. The flying height of a magnetic head slider (1) can be controlled against a change of temperature so that the flying height of the magnetic head slider (1) is low at low temperatures and high at high temperatures, thereby the variations of the coercivity of a magnetic disk (2) can be cancelled. Further, by setting the rate of change of the crown value with respect to the change of temperature to 0.26 to 0.62 nm/° C., the flying height can be controlled so that the flying height becomes low at low temperatures and high at high temperatures, while maintaining the uniformity of the profile of the flying height of the magnetic head slider (1) from the inner periphery to the outer periphery of the magnetic disk (2).

  • Patent number: 6967528
    Abstract: The present invention is a variable gain amplifier for amplifying a radio frequency signal by using a field effect transistor for signal amplification. The variable gain amplifier includes: an input impedance correcting means for correcting the input impedance when varying the gain at the input side of the field effect transistor for signal amplification; an output impedance correcting means for correcting the output impedance when varying the gain at the output side of the field effect transistor for signal amplification; and an amplifier bypass means for passing the radio frequency input signal to the output side by skipping the field effect transistor for signal amplification when varying the gain. According to the present invention, a variable gain amplifier is favorable in the voltage standing wave ratio (VSWR) at the input and output end regardless of presence or absence of gain variation, and the gain attenuation amount can be arbitrarily set.
