摘要： PURPOSE: To prevent deterioration of pump efficiency and reduce noises by setting circumferential width of a valve block at a partition in the vicinity of a top dead center of a piston asymmetircally to the top dead center. CONSTITUTION: A left end 11a of a partition 11 of a valve block 6 in the vicinity of a top dead center P of a piston 4 coincides with the top dead center P1 , while a right end 11b is located at a position on a right side of the top dead center P1 by about 18 degrees. Circumferential width of the valve block 6 is formed asymmetrically to the top dead center P1 . With such a construction, when a rotor 1 is rotated in the direction of A, a cylinder hole 2 is not blocked until an oil inlet 3 of the cylinder hole 2 reaches the top dead center P1 . Accordingly, the inlet 3 is closed before reaching the top dead center P as in the case that the partition 11 is formed symmetrically to the top dead center P1 . It is thus possible to prevent increase of pressure inside the cylinder, and generation of noises.

摘要： PURPOSE:To measure the arranging interval between lugs accurately and precisely in a short time by providing a driving device for moving a base bodies at a specified speed in a specified direction, rollers, a displacement sensor, a pulse generating part and a control part. CONSTITUTION:A motor 26 is driven, and a drum 22a is rotated. Thus a track belt 10 is turned. When a roller 33 is in contact with an inner surface 11a of a base body 11 of the belt 10, the detected signal from a displacement sensor 34 is not inputted into a control part 50. When a roller 32 comes into contact with a lug 12-1, the roller 32 is displaced with respect to the inner surface 11a. When a specified amount is exceeded, the detected signal from the sensor 34 is inputted into a control part 50. The roller 32 is slid on the lug 12-1. When the displacement amount becomes less than the specified amount, the detected signal is stopped, and roller 32 comes into contact with a reference surface. When the belt is turned and the roller 32 comes into contact with a lug 12-2, the same operation as before is performed. The control part 50 computes the arranging interval of the lugs based on the counted number of a pulse counter 43 from the previous input time of the detected signal to the input time at this time and a preset pulse period.

摘要： PURPOSE:To detect a pattern accurately and precisely by providing a driving device, a probe, a displacement detecting part and a control part. CONSTITUTION:A base body 11 is moved at a specified speed in the specified direction with a driving device 20. Bodies to be detected (lugs 12) are also moved in the same direction at the same speed. In this movement, when a probe (roller 32) is transferred from a contact state with the surface of the base body 11, i.e. a reference surface, to a contact state with one body to be detected, the displacement with respect to the reference surface is linearly detected with a displacement detecting part 30. The detected value is inputted into a control part 40, and the displacement pattern is temporarily stored. Then, the base body 11 is further moved, and the probe is transferred to a contact state with a body to be detected in the next stage. The displacement with respect to the reference surface is detected, and the detected value is inputted into the control part 40. In the control part 40, the displacement pattern of the body to be detected in the next state is compared with the stored displacement pattern of one body to be detected. When both patterns agree, it is judged that the body to be detected at the next stage has the specified pattern. When both patterns disagree, it is judged that the body to be detected at the next stage is the defective pattern.

摘要： PURPOSE:To shorten a measuring time by using a time point when the front edge of a body has cut a first light path as a reference, obtaining a time t1 from the reference point to the time point when the front edge of the body cuts a second light path and a time t2 until the rear edge of the body releases the cut state of the first light path, and computing a deviation P from the reference size of a moving body by the specified expression. CONSTITUTION:The interval between light axes OA 1 and OA 2 of first and second detecting parts 31 and 32 is made to be W1. The moving speed of a cleat 11 is made to be V (constant). The time during which the front edge of the cleat 11 passes a part between light axes OA 1 and OA 2, i.e. the time from a time point when an electric signal ES 1 from a photodetector 31b is switched from a high level to a low level to a time point when an electric signal ES 2 from a photodetector 32b is switched from a high level to a low level, is made to be t1. A time from a time point when the front edge of the cleat 11 has passed the light axis OA 1 to a time point when the rear edge passes through the light axis OA 2 is made to be t2. Then, a deviation P from the reference size of the moving body is computed by using the times t1 and t2 based on the expression (DELTAt1 and DELTAt2 are preset correcting values).
