Publication number: 20100294097Abstract: In a brush cutter (100), when it is determined based on acceleration information including frequency components, supplied from an acceleration sensor (24) included in the brush cutter (100) that the acceleration shows a peak in a range of frequencies lower than 100 Hz, the flow moves to step S5 to amplify the acceleration peak. In next step S6, the acceleration peak is compared with a threshold. When the result of comparison shows that the acceleration peak is higher than the threshold, the flow moves to step S7 to produce a safety signal. The safety signal is output from the controller (26) to a high voltage generation circuit (30) to stop generation of a high voltage in the high voltage generating circuit (30). In this manner, the acceleration sensor (24) is used to detect any unexpected, sudden danger, while diminishing influence of the acceleration caused by vibration inherent to the own nature of the work apparatus, its intended regular operation and its posture change in regular operation.Type: ApplicationFiled: May 20, 2010Publication date: November 25, 2010Applicant: YAMABIKO CORPORATIONInventors: Tatsuya Aoki, Tadashi Ishimura

Patent number: 5345836Abstract: Disclosed herein is a shift lever device for an automatic transmission for use in a vehicle such as an automobile, etc. A female connector is disposed in a position inwardly away from the outer periphery of a shift lever and laid on an axially-extending portion thereof. In addition, the female connector is held in position by a connector support disposed below the female connector. A knob is inserted into and fixed to one end of the shift lever. A male connector and a switch are fixed to an intermediate portion of the knob. When the knob is inserted into the shift lever, the male connector is disposed in such a way as to be fitted into the female connector. It is therefore possible to form the knob so as to cover the one end of the shift lever on a small scale.Type: GrantFiled: November 10, 1992Date of Patent: September 13, 1994Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Yoshinobu Yokoyama, Tatsuya Aoki, Etsuo Shimizu
