Title: Four-leg type robot and control method for high motion gait
Inventor: TAKEUCHI HIROYOSHI
IPC: B62D57/032
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To realize a high motion gait by generating supporting force in the vertical direction with rear legs, accelerating a robot with the frictional force of the rear legs with a floor, and decelerating the robot with the frictional force of front legs with the floor. SOLUTION: When a robot body 4 is accelerated forward by the frictional force of rear legs 2 with a floor, the inertial force -mx is generated in the horizontal direction on the robot body 4. No force other than supporting force is generated in the vertical direction on the rear legs 2 at this time. The moment I of the rear legs 2 can be described as Iθ=-mxz+mgx. If the first term is larger than the second term, the robot body 4 starts rotating backward, front legs 1 and a barrel are separated from a floor, and the center of gravity of the robot body 2 can be advanced forward. The overturning moment to lift the rear legs 2 is generated by the decelerating force when the front legs 1 are grounded on the floor. A periodic leg motion can be made if the rear legs 2 are returned forward at this time.

Abstract: PURPOSE:To adjust the focus to a desired object to be photographed even at the time of flash photographing by executing the focusing, based on focusing information detected before a shutter release is executed after pre-light emission is executed at the time of flash photographing accompanied with the pre-light emission. CONSTITUTION:At the time of flash photographing for which a pink-eye effect prevention light emitting device 103 is used, focusing information is detected by a focusing information detecting means 101 before a shutter release is executed after a pre-light emission by the pink-eye effect prevention light emitting device 103 is executed, and based on its information, automatic focusing is executed by an automatic focusing means 104. Subsequently, after this automatic focusing, the shutter release is executed, and also, it is irradiated with an irradiating light for illuminating an object to be photographed. In such a way, a time lag to the shutter release after detecting the focusing information is suppressed to the minimum, and even at the time of flash photographing accompanied with a light emission for preventing a pink-eye effect, the focus can be adjusted surely to a desired object to be photographed.

Abstract: PROBLEM TO BE SOLVED: To detect secondary electrons without lowering detection efficiency to attain an even sample image by setting voltages of a plurality of electrodes, which are to guide the secondary electrons generated from a sample to a secondary electron detector, to a plurality of combinations. SOLUTION: A first and a second voltage states that are respectively different in their conditions are set to electrodes 17a to 17c and a sample 8 by a voltage control power supply 18a to 18c and 19. A secondary electron 14 from the sample 8 is accelerated to the electron source side by a negative voltage set to the voltage control power supply 19, for application to the sample and travels to the electron source sides while being converged by a convergent magnetic field formed by a lens magnetic field generated by an objective lens electrode and applied voltages to the electrodes 17a to 17c.

Abstract: PURPOSE:To weaken a rising force induced by the draft of oily smoke or the like and introduce said smoke to an intake port at the same time so that it may be effectively exhausted by discharging a small amount of auxiliary air toward the front of a range in a substantially horizontal direction from a first discharge port installed on the upper part of an intake port of a flue gas duct laid out near said range and discharging simultaneously a small amount of auxiliary air in an intake direction from a second discharge port installed to said range. CONSTITUTION:A flue gas device A is provided with a flue gas duct 17 where one end is opened both in the rear of a range 11 and on the side of a burner 12 in a horizontal direction, thus forming an intake port 13 while the other end forms a discharge port 16 with a blower 15 for discharge service laid out therein. A first discharge nozzle 18 is provided on the upper part of the intake port 13 while a second discharge port 19 is provided on the range at the same time. A small amount of auxiliary air current discharged from the discharge port 18 in a substantially horizontal direction toward the front of the range 11 serves to weaken the force of a rising air current induced by the draft of oily smoke or the like, and at the same time, the auxiliary air current discharged from the discharge port 19 introduces the oily smoke from the front side of the range 11 to the intake port 13. This construction makes it possible to collect oily smoke of the like by a small amount of air capacity effectively, thereby inhibit the drop in the effect of cooling and heating operation, and exhaust smoke at a low level of noise.
