The apparatus includes a storage device for storing a minimum formable distance between first regions or second regions adjacent to each other, and a controller calculating a distance between the first regions or second regions adjacent to each other in the screen and, when the distance of the region of a screen that corresponds to a gradation value of an input image and has a first pattern is smaller than the minimum formable distance, selecting a screen corresponding to the gradation value of the input image and having a second pattern.

Abstract: An assistance-limit recognizing device for recognizing a limit of assistance made by a vacuum booster that is configured to assist an operating force applied to a brake operating member. A communication between a variable pressure chamber and a negative pressure chamber of the vacuum booster is established, when the operating force is not applied to the brake operating member. A communication between the variable pressure chamber and the atmosphere is established while the communication between the variable pressure chamber and the negative pressure chamber is cut off, when the operating force is applied to the brake operating member, whereby the operating force applied to the brake operating member is assisted based on a pressure difference between a pressure in the negative pressure chamber and a pressure in the variable pressure chamber.

Abstract: A first screen group and a second screen group are stored in an image forming apparatus. In the first screen group, the first region expands with increasing gradation value based on a first rule. In the second screen group, the first region expands with increasing gradation value based on an independent second rule different from the first rule. A screen selector relocates a first portion and a second portion such that the first portion and the second portion are joined by a second region that is not a toner adhesion control target, when the first portion and the second portion are adjacent as a result of the selection of the screen in each unit region of the input image. The first portion includes the screen included in the first screen group, and the second portion includes the screen included in the second screen group.

Abstract: The similarity groups of the pressure differential—current characteristics of solenoid valves are measured in advance, and the measurement results are used to select the solenoid valves to be used for first to fourth pressure increase control valves. Only solenoid valves in the same region in terms of their similarity group of the pressure differential—current characteristics are used for the first to fourth pressure increase control valves. A board on which the first to fourth control valves are mounted is provided with a mark unit that indicates the similarity group of the pressure differential—current characteristics of the first to forth pressure increase control valves. The mark unit includes a resistor. A brake ECU uses the resistance value of the resistor to identify the similarity group of the pressure differential—current characteristics of the first to fourth pressure increase control valves.
