  • Publication number: 20230094325
    Abstract: A gas component detection device includes a column, a sensor, a flow path, and a flow path switch. The column separates a component of gas to be detected. The sensor is, for example, a semiconductor sensor, is connected to the downstream side of the column, and detects a component of gas to be detected. The flow path connects the column and the sensor. The flow path switch is arranged between a flow path and a flow path. The flow path switch switches between and executes a measurement mode in which gas to be detected discharged from the column flows into the sensor, and a discharge mode in which gas to be detected discharged from the column is discharged to the outside.

  • Patent number: 10394020
    Abstract: An image forming apparatus includes a light scanning device, a light detection unit, and a positional-deviation-amount calculation unit. The light detection unit includes a slit-shaped first light detection region and a slit-shaped second light detection region arranged to have mutually different angles with respect to a scanning direction of the light beam, and outputs a detection signal when the light beam passes through each of the light detection regions. The positional-deviation-amount calculation unit calculates a time period until when the light beam passes through the second light detection region from when the light beam has passed through the first light detection region for each scan of the light beam based on the detection signal output from the light detection unit, and calculates a variation characteristic of a positional deviation amount in a sub-scanning direction of the light beam associated with rotation of the polygon mirror.

  • Patent number: 9955031
    Abstract: A laser scanning device includes light source, deflection portion, image forming lens, a block position setting portion, and a light source control portion. The image forming lens condenses a light beam deflected by the deflection portion on a scanned surface, and causes the light beam to be scanned on the scanned surface in a scanning direction at an equal speed. The block position setting portion sets one or more block areas which each include a plurality of section areas sectioned from each other on the scanned surface in the scanning direction. The light source control portion controls the light source to irradiate the light beam to the plurality of section areas at a plurality of irradiation timings that are determined for each of the block areas. The block position setting portion shifts set positions of the block areas along the scanning direction for each scan of at least one line.

  • Patent number: 9917971
    Abstract: A laser scanning device includes a light source, a deflection portion, an image forming lens, and a light source control portion. The light source emits a light beam. The deflection portion causes the light beam emitted from the light source to scan a scanned surface by deflecting the light beam at a predetermined deflection angle. The image forming lens condenses the deflected light beam on the scanned surface, and causes the light beam to be scanned on the scanned surface in a scanning direction at an equal speed. The light source control portion controls the light source to irradiate the light beam to at least one section area among a plurality of section areas sectioned from each other in the scanning direction on the scanned surface, at a plurality of irradiation timings determined based on a position of the at least one section area in the scanning direction.
