A clutch including a drive shaft, drive side rotation body, driven shaft, driven side rotation body, clutch housing, and lock member is disclosed. During non-rotation of the drive side rotation body, when the driven side rotation body is rotated, the lock member is pushed by the driven side rotation body and moved outward in a radial direction thereby bringing the contact portion into contact with the inner circumferential surface of the clutch housing. During rotation of the drive side rotation body, the drive side rotation body pushes a drive side cam surface in the rotation direction, and the drive side cam surface acts to move the lock member inward in the radial direction and push the lock member against the driven side rotation body. Thus, the lock member is sandwiched between the drive side rotation body and the driven side rotation body thereby coupling the drive side rotation body and the driven side rotation body with the lock member to be integrally rotatable.

In a PON system having a station side apparatus (OLT) and plural home side apparatuses (ONUs), the station side apparatus includes an uplink frame transfer processing part controlling frame transfer from the home side apparatus to the station side apparatus, a transfer database managing the destination of frame transfer from the station side apparatus to the plural home side apparatuses, a statistical counter part counting transfer data amount for each user, and a user usage state management part managing the user usage situation. The user usage state management part determines the user usage situation (used/unused) based on the state monitoring result of any one or all of parts described above, switches the operation of the uplink frame transfer control part depending on the usage situation and adjusts DBA control frame amount between the station side apparatus and the home side apparatus.

A clutch is provided that includes an annular clutch housing, a driving-side rotor, a driven-side rotor having a control surface, and a rolling element located between the inner circumferential surface of the clutch housing and the control surface. The control surface faces radially outward in the clutch housing. When the driving-side rotor rotates, the rotational driving force of the driving-side rotor is transmitted to the driven-side rotor. When the driving-side rotor is driven to rotate, the rolling element rotates together with the driven-side rotor. When the driving-side rotor is not driven to rotate, the rolling element is held between the inner circumferential surface of the clutch housing and the control surface so as to prevent the driven-side rotor from rotating. The driven-side rotor includes a driven-side coupling portion that can be coupled to and integrally rotatable with the driving-side rotor. The driven-side coupling portion and the control surface are provided at different positions in the axial direction.

A commutator having a plurality of segments, a short-circuit member assembly, a holding portion, and a plurality of spacing members is disclosed. The short-circuit member assembly includes a plurality of short-circuit pieces. Each short-circuit piece has an outer terminal, an inner terminal arranged radially inward from the outer terminal and circumferentially offset from the outer terminal at a predetermined offset angle, and a connecting portion connecting the inner terminal to the outer terminal. The holding portion covers the segments and at least a portion of the short-circuit member assembly to hold the segments and the short-circuit member assembly. The spacing members each have an insulated support portion and a plurality of insulated spacing projections formed integrally with the support portion. Each support portion extends in a radial direction of the short-circuit member assembly. The spacing projections are arranged in the direction in which the corresponding support members extend in such a manner that the spacing projections are each provided between the corresponding circumferentially adjacent pair of the connecting portions.

A volume measuring apparatus is provided with: an acoustic tube whose one end is communicated with a container in which an object to be measured is contained; another container communicated with the other end of the acoustic tube; a partition chamber which defines a sealed space disposed adjacent to the another container and which includes a partition plate for dividing the sealed space and an inner space of the another container; and an electromotive-type speaker which is disposed in the sealed space and whose acoustic wave output surface is disposed opposite to the partition plate. A processing device obtains a volume of the object to be measured, on the basis of an acoustic signal associated with an acoustic wave outputted into the another container via the partition plate from the acoustic wave output surface.

A drive apparatus for opening and closing a window glass provided in a door having an inner panel is disclosed. The drive apparatus includes a motor provided in the door and a regulator that receives drive force from the motor and selectively open and close the window glass. The door noise includes motor operating noise and vibration transmission noise that is generated when vibration of the motor is transmitted to the inner panel via the regulator. The motor is configured such that a first-order frequency component in vibration of the motor is greater than any other nth component (n is an integer greater than or equal to two), so that the first-order frequency component in the door noise is greater than any other nth frequency component (n is an integer greater than or equal to two).

A motor controller that outputs a drive signal to a direct-current motor to drive the motor is provided. The motor controller includes a drive circuit that generates the drive signal. The drive circuit superimposes on a direct-current voltage an alternating-current component having a frequency in the audible frequency range of the human ear, thereby generating the drive signal.

Provided is a nut that resists being loosened and is easy to be tightened. A nut 600 includes a nut main body 10 having a tapped hole 30 formed therein; an annular member 41 formed on the side of a top surface of the nut main body 10; and an outer frame member 45 formed on the side of an outer edge of the annular member 41. The annular member 41 includes a second end portion 42b in contact with a top surface 11 of the nut main body 10 and a first end portion 42a located opposite to the second end portion 42b. A top surface of the first end portion 42a is located above a top surface of the second end portion 42b. A first gap 40 is formed between the first end portion 42a and the top surface 11 of the nut main body 10. A second gap 49 is formed between a side surface of the annular member 41 and an inner wall 47 of the outer frame member 45. The top surface of the first end portion 42a of the annular member 41 is located above a top surface 46 of the outer frame member 45. The inner wall 47 of the outer frame member 45 is inclining while tapering in an upward direction.
