An image reading device including a contact glass; a reading unit; a pressure plate; a pressure-plate opening/closing sensor; and circuitry. The circuitry determines a presence or absence of external light input to a space between the pressure plate and the surface of the contact glass based on image data obtained by the reading unit when the light source is turned off; compares read data according to light emitted from the light source and received by the image sensor when the pressure plate is closed, with read data of a reference value obtained when the pressure plate is completely closed, to obtain a difference and determine a state of the read data based on the difference; and determines whether the pressure plate is open or closed based on a determination result of the presence or absence of external light and on the difference.

A robot 1 is equipped with a leg 2 including a knee joint 16 connecting a thigh link 32 and a crus link 34. The knee joint 16 is equipped with a connecting rod 44, one end of which is connected so as to be freely rotatable with respect to an axis 40 of the crus link 34 and the other end of which is connected so as to be freely rotatable to an axis 42 of the thigh link 32, and a distance varying mechanism 50 which changes the distance between an axis 60 of the crus link 34 and an axis 56 of the thigh link 32 by a driving force of an electric motor 40. When a bending angle of the knee joint 16 is 0 degree, a sum of the distance between the axis 40 and axis 42 and the distance between the axis 60 and the axis 56, is smaller than the distance between the axis 40 and the axis 56.

A brushless motor according to the present invention is provided with a tubular stator case, a stator core fitted into the stator case, and a rotor rotatably supported via a bearing inside the stator core. The stator core includes a tubular yoke portion and a plurality of split cores which are detachably mounted on the tubular yoke portion. A plurality of commutating-pole teeth which extend radially inward are integrally formed on an inner peripheral surface of the tubular yoke portion at regular intervals in the peripheral direction of the tubular yoke portion; and a root portion of each of the commutating-pole teeth has inclined shoulders which are gradually enlarged radially outward.

In a legged mobile robot having a body and legs connected to the body, a seating aid is provided at its body so as to enable to sit on a seat. With this, the space occupied by the robot can be decreased to reduce space during storage and transport, and also enhance safety in the course of transport. In addition, maintenance work is simplified because immobilization in the seated condition is possible. Still further, the range of works is expanded to enable deskwork and the like. Further, the seating aid is provided at a location that is rearward of a center of gravity of the robot when the robot is seated. With this, the moment acting on the robot about the center of gravity during seating does not operate to tilt the robot rearward and, therefore, the robot can be enabled to keep a stable posture from before to after sitting down.

The present invention provides a method for manufacturing a bonded wafer, which includes at least the steps of bonding a bond wafer and a base wafer, grinding an outer peripheral portion of the bonded bond wafer, etching off an unbonded portion of the ground bond wafer, and then reducing a thickness of the bond wafer, wherein, in the step of grinding the outer peripheral portion, the bonded bond wafer is ground so as to form a groove along the outer peripheral portion of the bond wafer to form an outer edge portion outside the groove; and in the subsequent step of etching, the outer edge portion is removed together with the groove portion of the bond wafer to form a terrace portion where the base wafer is exposed at the outer peripheral portion of the bonded wafer. Thus, it is possible to provide a method for manufacturing a bonded wafer, which can reduce the number of dimples formed in a terrace portion of a base wafer upon removing an outer peripheral portion of a bonded bond wafer.

A legged mobile robot leg structure is provided in which a lower leg part (24) is connected to the lower end of an upper leg part (23) through a knee joint (27), a foot part (25) having a six-axis force sensor (60) is connected to the lower end of the lower leg part (24) through an ankle joint (28), and the ankle joint (28) supports the foot part (25) so that the foot part (25) can pitch around a lateral axis (Ly) and roll around a fore-and-aft axis (Lx) relative to the lower leg part (24). A pitch motor (34) for making the foot part (25) pitch around the lateral axis (Ly) is supported on the lower leg part (24) at a position above the ankle joint (28), and a roll motor (35) for making the foot part (25) roll around the fore-and-aft axis (Lx) is supported on the lower leg part (24) at a position above the ankle joint (28). The driving force for driving the lower leg part (24) can thereby be reduced by decreasing the moment of inertia around the knee joint (27), and the influence of noise of the motors (34, 35) on the six-axis force sensor (60) provided on the foot part (25) can be minimized.
