  • Patent number: 10370769
    Abstract: In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.

  • Patent number: 10274897
    Abstract: A governor includes a balance spring including a base member made of silicon, for example, and a balance wheel. The balance spring includes a coating film of DLC that is applied to a surface of the silicon base member to improve the strength of the balance spring. A spring constant of the balance spring changes in accordance with the temperature change. A moment of inertia of the balance wheel changes in accordance with the temperature change. A change in an oscillation period due to the temperature change is suppressed by the change in the spring constant of the balance spring and by the change in the moment of inertia of the balance wheel.

  • Patent number: 9798804
    Abstract: According to an embodiment, an information processing apparatus includes a storage unit, a detector, an acquisition unit, and a search unit. The storage unit configured to store therein voice indices, each of which associates a character string included in voice text data obtained from a voice recognition process with voice positional information, the voice positional information indicating a temporal position in the voice data and corresponding to the character string. The acquisition unit acquires reading information being at least a part of a character string representing a reading of a phrase to be transcribed from the voice data played back. The search unit specifies, as search targets, character strings whose associated voice positional information is included in the played-back section information among the character strings included in the voice indices, and retrieves a character string including the reading represented by the reading information from among the specified character strings.
