  • Publication number: 20120044399
    Abstract: An apparatus includes: an element that receives subject light from a subject to generate image data; a section that generates a recording image to be recorded on a recording medium from the image data when a first mode is set; a section that generates a second display image, which allows display of a live-view image, from the image data when a second mode is set, and that generates a first display image, which allows display of an image identical to the recording image, from the image data when the first mode is set; a section that sequentially displays the first display image or the second display image; a section that detects a specific state of the apparatus that obstructs recording of an imaging object onto the recording image; and a section that controls switching between the first mode and the second mode on the basis of the detection results.

  • Patent number: 8118699
    Abstract: A sprocket for a chain drive using a roller or bushing chain has a plurality of different pitch angles, including both pitch angles larger than the standard pitch angle, and pitch angles smaller than the standard pitch angle. The number of pitch angles in the sprocket larger than the standard pitch angle is greater than the number of pitch angles in the sprocket smaller than the standard pitch angle. The sprocket teeth are integrally molded with the sprocket by sintering.

  • Publication number: 20110063122
    Abstract: Signals from a plurality of sensors (vibration sensors, temperature sensors, and humidity sensors) disposed at places on a machine are input through a communication circuit to a numerical controller that controls the machine. The numerical controller uses vibration information, temperature information and humidity information obtained from these sensors to determine whether the machine is in an abnormal state.

  • Patent number: 7898264
    Abstract: Disclosed is an insulation deterioration detection device that can accurately detect insulation deterioration in multiple motors by a simple circuit configuration. When detecting insulation deterioration, one end A of a smoothing capacitor is connected via a first switch to ground, and the other end B is connected via a second switch to motor windings; in this condition, link voltage is measured by a voltage measuring circuit provided in a converter unit, and the measured link voltage value is transmitted to a microcomputer in each inverter unit via serial communication. Current flowing via motor insulation resistance Z1, Z2 is measured by a current measuring circuit provided in each inverter unit, and the microcomputer calculates the value of the insulation resistance Z1, Z2 from the link voltage value and the current value.

  • Publication number: 20110041014
    Abstract: A method for a computer including a processor that is capable of counting invalidation of translation lookaside buffers and generating an interrupt at the occurrence of the invalidation, the invalidation being performed by an operating system upon switching between application programs, includes acquiring identification information of application programs from the operating system and storing the identification information as a first list; detecting an interrupt generated from the processor at the occurrence of switching from a first application program to a second application program; and when the interrupt is detected, acquiring the identification information of the first and second application programs from the operating system or the mechanism and comparing the acquired identification information with the first list to determine whether either of the first and second application programs is a program that has been created or disappeared.

  • Patent number: 7830478
    Abstract: An LCD device includes a lower panel having a first substrate; an organic layer formed on the first substrate; a trans-reflection layer formed on the organic layer and having a reflection area reflecting a portion of incidence light from exterior and a transmission area transmitting other portion of the incidence light; color filters formed on the trans-reflection layer; an overcoating layer formed on the color filters; and a common electrode formed on the overcoating layer. A portion of the overcoating layer corresponding to the reflection area is thicker than a portion of the overcoating layer corresponding to the transmission area. The LCD device also includes an upper panel including a second substrate facing the first substrate with a predetermined gap; thin film transistors formed on the second substrate; and pixel electrodes connected to the thin film transistors; and a liquid crystal layer disposed between the lower and upper panels.
