  • Publication number: 20170237060
    Abstract: With a battery using a flexible outer package, electric current is reliably interrupted when the temperature is increased due to the occurrence of abnormality, thereby preventing excessive heat generation. A battery 1 includes a battery element 10, a pair of first terminals 11 that are electrically connected to the battery element 10, a flexible outer package 13, and a second terminal 12. The outer package 13 is partitioned into a first chamber 13a in which the battery element 10 is sealed and a second chamber 13b which is adjacent to the first chamber 13a. The second terminal 12 is led out from the second chamber 13b to the outside of the outer package 13 so that one first terminal 11 is made electrically connectable to an external wiring through the second chamber 13b. A gas generation material 14 which generates a gas at a predetermined temperature or higher is sealed in the second chamber 13b.

  • Patent number: 9646374
    Abstract: Optical image data is acquired by irradiating a pattern with light emitted from a light source. A threshold value is specified by internally dividing a minimum value and a maximum value of a signal amount of reference image data by a division ratio. A position corresponding to a signal amount of a threshold value is determined as an edge of a pattern of the reference image data. A position of a signal amount equal to the threshold value is determined as an edge of the pattern of the optical image data. A line width error is obtained as a difference between a first line width of the optical image data and a second line width of the reference image data. A new threshold value is specified in the case of fluctuation of a light quantity of the light source or decrease of a contrast value of the optical image data.

  • Patent number: 9612516
    Abstract: A projection type image display apparatus (1) comprises a focus correction system (30). The system includes a temperature detection mechanism (16) for measuring temperature in the vicinity of a projection lens group (13), a correction amount calculation unit (18) for calculating a correction amount for correcting the focus shift caused by a temperature change, and a driving signal generation unit (19) for generating, based on the correction amount, a driving signal for driving a focus adjustment mechanism (15). If the user performs a focus adjustment using a focus operation input unit (23), a focus operation determination unit (21) determines that a focus adjustment has occurred independently of the focus correction system and changes a correction condition stored in a memory (20).
