    摘要: An image forming apparatus includes an image forming unit, an exposure unit, a detection unit, a storage unit, and a control unit. The image forming unit includes a photosensitive member on which an electrostatic latent image is formed. The exposure unit exposes the photosensitive member. The detection unit detects that a reference position disposed on the photosensitive member has reached a predetermined position. The storage unit stores correction data for correcting unevenness of potential characteristic in the photosensitive member. The control unit controls an exposure intensity of the exposure unit at each position on the photosensitive member based on the correction data.

    摘要: An electronic component substrate (1-1) includes an insulating base (10) and a flexible circuit board (20) mounted on the insulating base (10). The flexible circuit board (20) is a synthetic resin film provided thereon with terminal patterns (29) and a conductor pattern (25) whose surface is slidingly contacted with a slider. The insulating base (10) is a synthetic resin molded piece. The flexible circuit board (20) is insert-molded to the insulating base (10). The electronic component substrate (1-1) is produced by preparing the flexible circuit board (20) and first and second mold members (41, 45) having a cavity (C1) with a shape that corresponds to the external shape of the electronic component substrate (1-1). Then, the flexible circuit board (20) is accommodated in the cavity (C1) between the first and second mold members (41,45), and the cavity (C1) is filled with a molten molding resin. After the molding resin has solidified, the first and second mold members (41, 45) are removed.

    摘要: A gas sensor element is designed to determine the concentration of a selected component contained in gas and includes a sensor cell. The sensor cell is equipped with two electrodes one of which is exposed to a gas chamber into which the gas flows from outside the gas sensor element. The electrodes connect with leads extending to external terminals exposed to the atmospheric air. One of the leads connecting with one of the electrodes exposed to the gas chamber is made of material which includes a mixture of a metallic composition and a ceramic composition and contains 7% or less by weight of the ceramic composition based on a total weight of the mixture. This results in a decrease in porosity of the lead, which reduces the intrusion of oxygen gas into the gas chamber, thereby enhancing the accuracy in determining the concentration of the selected component of the gas.
