  • Publication number: 20240291458
    Abstract: An electronic component includes a filter, a first phase-shift circuit, a second phase-shift circuit, and a stack. The first phase-shift circuit includes a first inductor provided in a first path connecting an unbalanced terminal and a first balanced terminal, and a first capacitor provided between the first path and a ground in a circuit configuration. The second phase-shift circuit includes a second capacitor provided in a second path connecting the unbalanced terminal and a second balanced terminal, and a second inductor provided between the second path and the ground in the circuit configuration. The first inductor and the second inductor are arranged in a direction parallel to a stacking direction.

  • Publication number: 20170057856
    Abstract: Provided is a method for producing an inexpensive chalcogenide optical element having high performance. An inside of chalcogenide glass is also heated uniformly by heating the chalcogenide glass with an infrared ray (light LI). Therefore, a molded lens LE hardly causes a crack or the like, a work piece WP as a block of the chalcogenide glass can be softened in a short time, and time required for molding can be shortened. In addition, direct heating with an infrared ray (light LI) allows heating and cooling to be performed in a short time. Therefore, an effect of volatilization, oxidation, crystallization, or the like can be reduced, and the lens LE having a high transmittance can be molded. Press molding can be performed while the temperature of the second mold die 12 is lower than that of the glass. Therefore, the lens LE hardly causing fusion and having an excellent appearance can be molded with a low maintenance frequency.

  • Patent number: 9309141
    Abstract: Method of manufacturing an optical element capable of providing a satisfactory shape accuracy even where a plurality of optical elements are molded. By providing a protruding portion 12d to change the flow of molten glass drop GD for an optical element with a forming mold 10, it is possible to make the glass drop GD for an optical element flow along an optical surface transferring surface 12a in the vicinity of edge side close to the drop point of the glass drop GD for an optical element, among the optical surface transferring surfaces 12a. According to this, even where a plurality of glass lenses 100 are collectively molded, it is possible to transfer an optical function surface 101a of the glass lens 100 to each optical surface transferring surface 12a with a high accuracy and to collectively manufacture the glass lenses 100 with a satisfactory shape accuracy.

  • Publication number: 20140116089
    Abstract: Provided is an apparatus for manufacturing an optical element, and a method of manufacturing an optical element, whereby variance of dropping positions of glass droplets can be suppressed even with a low-cost and simple configuration. The positions where the glass droplets are discharged from a discharged port 51c are controlled by having a predetermined force applied to the glass droplets from the wall surface of a passage 51b of a correcting member 51 in a non-contact manner, the glass droplets passing through the passage 51b. Therefore, variance of dropping positions of the glass droplets can be suppressed without surrounding the whole manufacturing apparatus. Consequently, a highly accurate optical element can be manufactured with the low-cost and simple configuration.

  • Publication number: 20140055860
    Abstract: To provide a lens unit producing method capable for positioning a lens array with high precision over a long period of time, a lens array, and a lens unit. When the first flat surfaces LA1f come in contact with the respective tapered surfaces HLD1, the glass lens array LA1 cannot rotate more than that for the holder HLD. Meanwhile, since the tapered surfaces HLD1 are regulated by the respective opposite first flat surface LA1f, the glass lens array LA1 cannot move more than that relatively to the holder HLD. That is, by holding the glass lens array LA1 with the holder HLD, the glass lens array LA1 can be positioned with high precision for the holder HLD.

  • Publication number: 20100077799
    Abstract: Since a lens droplet contacts with an outer shape regulation frame 3 at an early stage and is formed to be a glass lens 100 by pressure in a fluidized state with less deformation, a positioning datum surface 102b and so forth can be formed accurately. Also, as a result that the melt droplet contacts with the outer shape regulation frame 3 at the early stage, a shape of a side surface 103 of the glass lens 100 can be formed accurately, and centering process after formed can be omitted.
