Provided is a hybrid drive device including a main power source; an auxiliary power source; a main deformation part configured to be deformable in response to receiving a voltage from the main power source; and an auxiliary deformation part configured to connect to the main deformation part and to be deformable in response to receiving a voltage from the auxiliary power source.

Hybrid drive device

A measurement device () for a golf course green comprises: a distance measurement unit () having a pair of laser transmitter/receivers () for emitting a pair of laser beams (L; L, L), for distance measurement, outwardly at a predetermined emission angle with respect to the forward direction (CEN); a control unit () for generating hole-cup position information and hole-cup gradient information from an arithmetic operation of data on the distance measured by the pair of laser transmitter/receivers () of the distance measurement unit () and data on the emission angle; and an output unit () provided outside a casing () so as to output the hole-cup position information and hole-cup gradient information generated by the control unit ().

Non-contact measurement device for golf course green

A device for measuring an inclination of a green in a golf course. The device includes: a rotation member () having a weight member () provided eccentrically relative to a central axis of the rotation member such that the rotation member () freely rotates around a rotation shaft (), the rotation member () having horizontal and vertical measurement lines; a first casing () having an accommodation space (); and a second casing () fitted over the first casing (), the second casing () having first rotation graduations, a horizontal judge line (h) and a vertical judge line (v), wherein the rotation member () comes into close contact with both the first casing () and the second casing (), and then is stopped by a pressure generated between the first and second casings or by simultaneously pressing both a flange () of the rotation shaft and the first casing ().
