    摘要: An image density discrimination chart is used to discriminate a density of a test image printed by an image forming apparatus. The chart includes an exposing portion for exposing the test image when the chart is overlaid relative to a printed recording material, a first comparison image having an upper limit level of a latitude, permitted by the image forming apparatus, for image density of the test image, and a second comparison image having a lower limit level of a latitude, permitted by the image forming apparatus, for image density of the test image.

    摘要: A linear motor elevator includes a linear motor that is permitted motion within the hoistway. The linear motor is mounted in a manner permitting motion of the entire linear motor, including stator, through the hoistway. As a result, the length of the hoistway and the run of the elevator may extend beyond the length of the stator. In a particular embodiment, the linear motor is connected to a car in a configuration permitting the car to travel at approximately twice the speed of the linear motor within the hoistway. The moving element of the linear motor is connected to the car to permit the car and moving element to travel at the same speed relative to the hoistway. As a result, the moving element moves relative to the stator at half the speed of the car speed and the height of the hoistway may be approximately double the height of the stator.
