摘要:
A battery-operated driver-drill (1) includes an epicycle reduction gear unit (8) which encases a switchover sleeve (26) having inner teeth (27) and outer teeth (28). The gear unit (8) is rotatably mounted on second and third internal gears (19, 20) and integrally slidably connected with a slide pate (37). By operating the slide plate (37), the switchover sleeve (26) may be slid between a first position, in which the slide plate (37) engages one of the second and third internal gears (19, 20) while engaging axial ridges (29) of a first gear case (5), and a second position, in which the slide plate (37) simultaneously engages both the second internal gear (19) and a first carrier (10) adjacent to the second internal gear (19) while disengaged from the axial ridges (2).

An electric lawn mower may include a mower body including an electric motor, a cutting blade rotatably driven by the electric motor for mowing a lawn, a battery mount configured to hold a battery, and a lock including a key and a key receiver for locking and unlocking the electric motor. The key receiver may be spaced from the battery mount and when the key is inserted into the key receiver, the electric motor may be unlocked for operation.

A tool unit for a cutting device includes a rotary blade, a blade case for covering at least a part of the blade case, and a drive device mounted to the blade case for rotatably driving the rotary blade. A handle is attached to the drive device. The blade case has a front support portion. The handle has a rear support portion. When the tool unit is used for a portable cutting device, the front support portion can be vertically pivotally supported by a front portion of the base, and the rear support portion can be supported by a guide member such that a position of the rear support portion can be changed relative to the guide member for enabling adjustment of a cutting depth of the rotary blade into the workpiece. When the tool unit is used for a table cutting device, the front support portion can be vertically pivotally supported by the table.
摘要:
A technique that increases operability in changing the rotational speed of a spindle in a power tool. The rotational speed can be changed in three levels by utilizing a planetary gear mechanism. The third gear position is located in an intermediate position in the sliding direction of the speed changing part. The first speed change position is located on one side of the third speed change position. The second speed change position is located on the other side of the third speed change position. During operation, shifting between the first and third speeds can be done without going through the second speed each time. Further, shifting between the second and third speeds can be done without going through the first speed. Therefore, speed change shifting can be facilitated.

A picture display device including a picture display section for projecting an input picture signal; a light source for visualizing a picture in the picture display section; a moving picture detecting section for outputting a scanning line movement determination signal for every scanning line based on a movement amount of a picture signal for every scanning line; a PWM pulse generating section for controlling flashing of the light source; and a PWM control section for outputting a moving image specifying signal that specifies a moving image area included in a frame based on the scanning line movement determination signal to control the PWM pulse generating section. The PWM control section controls the PWM pulse generating section in a blinking mode by turning off the light source in a period for scanning the moving image area including a scanning line having a largest movement amount.
