Patent number: 10782523Abstract: In an on-vehicle display device, projection light output from a projecting unit is reflected on an intermediate mirror and is further reflected on a directional mirror. The reflected light is directed to a windshield glass as directed reflected light. In an adjustment operation, the directional mirror is rotated around tilting fulcrum parts by a driving unit to adjust the height of a virtual image formed in front of the windshield glass. In a retracting operation, the lower end of the directional mirror is largely moved forward by the driving unit, rotating the directional mirror with an abutting point between the directional mirror and the upper support acting as a fulcrum. This prevents external light (sunlight) from adversely affecting the projecting unit.Type: GrantFiled: December 18, 2018Date of Patent: September 22, 2020Assignee: Alpine Electronics, Inc.Inventor: Ichiro Kato

Patent number: 9799437Abstract: A plunger is formed of a soft magnetic material to have one end connected a regulation pin. A permanent magnet is affixed to a stationary portion to attract the plunger in a retreated direction. A coil generates a magnetic flux in an opposite direction of the permanent magnet to reduce a magneto attraction force, which attracts the plunger. A spring biases the regulation pin in an advanced direction. The spring applies a biasing force to the regulation pin to move the regulation pin in the advanced direction when electricity is supplied to the coil to reduce the magneto attraction force of the permanent magnet. A molded portion defines a magnet accommodation hole and a cover member covers the permanent magnet housed in the magnet accommodation hole. A magnetism detection unit is disposed on an opposite side of an inner surface of the cover from the permanent magnet.Type: GrantFiled: December 9, 2016Date of Patent: October 24, 2017Assignee: DENSO CORPORATIONInventor: Ichiro Kato

Patent number: 9076481Abstract: In a disk drive device, a guide section is formed to protrude from the front surface of a guide top and face a front panel of a frame member with a detection pin therebetween. The guide section forms an inclined side that faces a free end of the detection pin with a gap therebetween. If a disk is shifted from the middle of a disk insertion slot in the right-left direction and is inserted into the disk insertion slot, the detection pin is flexibly deformed by a disk insertion force and is brought into pressure contact with the inclined side. A component force is exerted on the detection pin in a direction in which the detection pin is moved away from the middle of the disk insertion slot in the width direction. The component force smoothly rotates a detection lever from an initial position to an operating position.Type: GrantFiled: November 19, 2014Date of Patent: July 7, 2015Assignee: Alpine Electronics, Inc.Inventor: Ichiro Kato
