Patent number: 7207680Abstract: If a projection display device includes a shifting mechanism for shifting a projection lens to adjust the direction in which the display projects an optical image, it is difficult to find suitable position where the display should be installed. Thus, the projection lens is fitted with a projection angle adjusting mechanism, which includes an adjusting dial having a scale representing the position of the lens relative to a display element. The projection display device is capable of automatically displaying on the projected optical image a scale image corresponding to the scale. The projection display also is capable of displaying on the projected optical image the position of the optical axis of the projection lens, which can be shifted by the adjusting mechanism.Type: GrantFiled: July 30, 2004Date of Patent: April 24, 2007Assignee: Hitachi, Ltd.Inventors: Futoshi Yamasaki, Hiroshi Oshima, Takuya Shimizu, Kazuo Shikita, Satoshi Nakayama

Patent number: 6484486Abstract: A mower unit of grass cutting machine has at least two blades. The left blade is rotatable clockwise, while the right blade is rotatable counterclockwise. A grass discharge passage is formed between the two blades. An endless rotational belt for transmitting drive to the two blades is offset forwardly in a region between the blades, thereby forming, between the blades, a space without the endless rotational belt. The grass discharge passage has an upper surface inclined rearwardly and upwardly to extend from a position forwardly of a pair of pulleys corresponding to the two blades.Type: GrantFiled: November 29, 2001Date of Patent: November 26, 2002Assignee: Kubota CorporationInventors: Hiroki Nagai, Nobuyuki Yamashita, Mikio Yuki, Hiroshi Oshima, Masatake Murakawa, Hiroshi Kawabata
