A tape autoloading device includes a tape leading-end processing device, which forms the leading end of a carrier tape into a predetermined shape, and a transfer device, which carries the carrier tape in a first direction different from the tape longitudinal direction and transfers the carrier tape to the next step. Tape leading-end processing device includes a feeding device for conveying the carrier tape along a conveyance path formed in a groove in a guide member, a pressing device for pressing the upper surface of the carrier tape, and a cutting device for cutting the leading-end of the carrier tape. The transfer device includes a guide device for guiding the carrier tape having a leading end formed into a predetermined shape, a gripping device for gripping the leading end of the carrier tape, and a moving device for moving the carrier tape in the first direction.

Tape autoloading device

A tape auto-loading device for loading a carrier tape including a cover tape gripping device configured to grip a distal end of the cover tape which is peeled off from the base tape, a linking device configured to link the temporary tape held by the temporary tape laying device to a distal end portion of the cover tape gripped by the cover tape gripping device, and a transfer device configured to transfer the temporary tape linked to the distal end portion of the cover tape from the temporary tape laying device to the tape feeder. The linking device includes a tape support member and a heating member each having respective shapes for pinching the predetermined portion in such a state of the predetermined portion being bent at a halfway position along a length in a tape's longitudinal direction.

Tape auto-loading device and tape linking method therefor

Portable electric blower body

An electric working machine may include a control device configured to control an electric unit, an operation member, a first switch configured to be operated by the operation member, and a second switch configured to be operated by the operation member. The operation member may pass a second position and a third position while the operation member moves to the first position. The first switch may be configured to transmit a first signal which changes as the operation member moves from the second position to the first position to the control device when the operation member moves between the second position and the first position. The second switch may be configured to transmit a second signal to the control device when the operation member passes the third position. The control device may be configured to control the electric unit based on the first signal and the second signal.

The present invention aims to provide a sound-absorbing material having sound absorption performance with an average sound absorption coefficient of 0.65 or more in the frequency domain of 800 to 2000 Hz. The present invention relates to a sound-absorbing material including: a fiber layer including a plurality of holes open to a surface thereof and having a thickness of 3 mm or more; and an inorganic material layer formed on the surface of the fiber layer, the holes being blind holes each penetrating through the inorganic material layer and having a bottom inside the fiber layer.

Sound-absorbing material

A component mounting machine which deals with a component remaining on a nozzle of a mounting head includes a board conveyance device conveying a board to a predetermined position, a component supply device accommodating multiple components therein, a component mounting device on which a mounting head which picks up and holds a component by vacuum pumping of a suction nozzle is installed and which mounts a component which is taken out from the component supply device onto a board which is conveyed by the board conveyance device, and a control device controlling each of the devices. The component mounting device performs lowering of the component, releasing the component with respect to the suction nozzle of the mounting head, a first lifting of the component to a middle height, a component pickup performed at the height of the first lifting, and a second lifting after the component pickup.

Component mounting machine for preventing release fail of a component

A chain saw may include a saw chain, a guide bar to which the saw chain is attached, a sprocket configured to move the saw chain along a periphery of the guide bar, a prime mover configured to rotate the sprocket, a housing that houses the prime mover, a bolt protruding from the housing and penetrating a hole provided in the guide bar, and a nut screwed to the bolt to fix the guide bar to the housing. The nut may be exposed to outside. A heat insulating structure may be provided on a heat transfer path between the nut and the guide bar.

Chain saw

A chain saw disclosed herein may include a motor configured to rotate a saw chain about a guide bar, a control unit configured to control a voltage applied to the motor, a body housing that houses the motor and the control unit, a battery detachably attached to the body housing, and a top handle provided above the body housing. The control unit may be disposed above the battery. In a rear view of the chain saw in a state where the chain saw is placed on a mount surface, the battery and the control unit may not overlap. In a top view of the chain saw in the state where the chain saw is placed on the mount surface, the battery and the control unit may overlap at least partially.

An inspection method of a suction nozzle. Air flow rates that flow in multiple reference pipes that have different sectional areas are measured. A proportionality factor between air flow rates and sectional areas of the reference pipes is calculated based on the measured air flow rates of the multiple reference pipes, and the sectional areas of the multiple reference pipes. An air flow rate in a suction nozzle that is an inspection target is measured. The sectional area of the suction nozzle is calculated based on the air flow rate of the suction nozzle and the calculated proportionality factor. The sectional area of the suction nozzle calculated in this manner is substantially fixed even when the pressure of air supplied from an air source fluctuates. The sectional area of the suction nozzle is proportional to the air flow rate that flows in an inner portion of the suction nozzle.

Inspection method

A power-operated air propelling work apparatus includes: an air flow pipe including an air inlet opening, an air outlet opening and a pipe wall formed between the air inlet opening and the air outlet opening to define an air flow passageway inside the pipe wall; an electric air propelling fan disposed within the air flow passageway for sucking in air from the air inlet opening and blowing out air from the air outlet opening; an apparatus housing surrounding and supporting the air flow pipe and forming a housing space between the apparatus housing and the air flow pipe; and a control circuit unit disposed within the housing space for controlling an operation of the electric air propelling fan, wherein the pipe wall is formed with an air passage hole by which the air flow passageway and the housing space communicate with each other.

Power-operated air propelling work apparatus
