  • Publication number: 20150131088
    Abstract: Provided is a technique which can properly invert a plurality of substrates at a time. To achieve this object, a substrate inverting apparatus includes: a support mechanism which supports a plurality of substrates in a state where the substrates are stacked vertically in a spaced-apart manner in a horizontal posture; and a clamping and inverting mechanism which clamps the plurality of substrates supported by the support mechanism respectively and inverts the plurality of substrates at a time. In the support mechanism, support members which support the substrate are moved to a standby position from a support position while being moved downward away from the center of the substrate as viewed in the vertical direction. On the other hand, in the clamping and inverting mechanism, clamping members which clamp the substrate are moved to a near position from a remote position by a clamping member drive part and are elastically biased by an elastic member toward side surfaces of the substrate at the near position.

  • Publication number: 20150115135
    Abstract: There is a need to provide a solid-state imaging apparatus capable of highly accurately analog-to-digital converting an analog voltage output from a pixel circuit. The solid-state imaging apparatus supplies a counter code to an integral A/D converter. The counter code CD includes 3-phase clock signals and gray signals. The clock signals each have a cycle equal to specified cycle multiplied by 8 and allow phases to shift from each other by specified cycle. The gray signals linearly increase count values at a cycle equal to specified cycle multiplied by 4. The counter code reverses only the logical level of a signal when a count value changes. A count value error can be limited to a minimum.

  • Patent number: 9001377
    Abstract: An image forming apparatus performs density correction. An image forming section forms a density detection image on a belt. A light source irradiates the image with light. A light receiving section receives light reflected from the image and outputs a plurality of intensity signals of the received light. An intensity obtaining section drives the belt and the light source, thereby illuminating the image a first number of times at intervals of a first distance as the belt runs, and the light receiving section receives the light reflected from the image, the first number of times being determined by at least the first distance and a second distance in which the first distance lies. A selecting section selects a second number of levels of light intensity from the plurality of intensity signals. A density correcting section performs print density correction using the second number of levels of light intensity.
