Abstract: An ion wind generator (20) is arranged on one side of a light source (1). The ion wind generator (20) produces an air current by negatively ionizing air by corona discharges at a needle electrode (21), or negative side, and drawing the negatively-ionized air at a cylindrical electrode (22), or positive side. The air current blows toward the light source (1) and removes heat generated by the light source (1). An ultraviolet ray from the light source (1) is introduced to a vent of the ion wind generator (20) by a first dichroic mirror (4) and a ultraviolet ray reflection mirror (17). Though air exhausted from the vent includes ozone (o3) produced by corona discharges, the ozone is decomposed by the ultraviolet ray.

Abstract: Modulated light (image light) which has been modulated by passing through a liquid crystal display panel passes through an apical angle variable prism (so-called, a vari-angle prism) and then is enlarged and projected by a projection lens. The apical angle variable prism is configured to change the prism apical angle with, for example, an electromagnetic actuator. The microcomputer calculates a projection optical axis correction value based on hand shake detection signals from a sensor and controls the aforementioned actuator based on the correction value. With this control, shakes of projected images due to hand shakes are prevented.

Abstract: An automatic seat belt system makes use of a drive member, for example, a drive tape for causing a runner to move back and forth along a guide rail mounted from the side roof to the center pillar within the room of an automobile. The drive tape is formed of a stretched tape made of a polyamide resin such as nylon 11 or nylon 12. The drive tape requires a low material cost and exhibits superb resistance to tensile and compression forces. The former advantage enables to reduce the overall manufacturing cost of the automatic seat belt system. On the other hand, the latter advantage permits use of a narrower and thinner drive tape, whereby permitting an overall size reduction to the automatic seat belt system. Owing to the possibility of using such a narrow drive tape, the drive tape can be arranged in a state bent in its widthwise direction without increasing its sliding resistance to any substantial degree.
