An ink jet printer is provided with an ink jet head, a recovery device, a timer, and a controller. The ink jet head discharges ink. The recovery device executes a recovery action to recover an ink discharging ability of the ink jet head. The timer measures time since a last recovery action of the recovery device. The controller selects an interval based on a printing history of the ink jet printer and controls the recovery device to execute the recovery action when the time measured by the timer becomes equal to the selected interval. The recovery action is performed at an appropriate timing.

Provided is a mounting apparatus which enables high levels of both maintenance/improvement of product quality and reduction of product cost by reliably preventing accidental contact of a mounting part with a mounting target part while enhancing the productivity. In S1, a contact detection start position Hs0 is set. In S2, a chip holding tool chucks an electronic part. In S3, S4, the tool is moved to a transfer position A, and then the tool is lowered to the Hs0 from the transfer position A. In S5, after the tool is lowered to the Hs0, the lowering speed is changed to a contact detection speed. In S6, it is determined whether or not the electronic part has come into contact with a substrate. If the result of the determination is YES, in S7, the lowering of the tool is stopped. In S8, the actual contact position Hc is measured. In S9, the next contact detection start position Hs1 is set, and Hs1 is set to Hs0 (Hs0-Hs1) so that the later steps reflect this setting. In S10, S11, after the electronic part is joined to the substrate by ultrasonic bonding, the tool is transferred to the transfer position A. In S12, it is determined whether or not a stop command is issued. If the result is YES, this flow is ended. If NO, the procedure returns to S2, and bonding is repeated.

A mounting apparatus capable of coping with high density mounting, narrower pitch mounting, cavity mounting and the like. In the apparatus, displacement amounts of a chip that is picked up from a wafer by a pick-up nozzle to be held by the pick-up nozzle, with respect to a reference attitude, are obtained, and when the chip is delivered to a mounting nozzle for actually mounting the chip onto a substrate, the displacement amounts are corrected while taking the displacement amounts into consideration, so that the mounting nozzle always holds the chip in a fixed attitude.

A controller for a machine capable of performing acceleration/deceleration control to which an optimal tangential acceleration within an allowable maximum acceleration for each axis is applied. A first interpolation section receives data obtained by analysis of a program by a command analysis section, an makes interpolating calculation in every first sampling period to output it into an intermediate memory. A tangential acceleration calculating section determines a tangential acceleration based on each segment and the allowable maximum acceleration for each axis to output it into the intermediate memory. A deceleration target velocity calculating section prepares an acceleration/deceleration pattern for a plurality of segments stored in the intermediate memory, to output it to the intermediate memory. An acceleration/deceleration control section performs acceleration/deceleration control based on the data in the intermediate memory so that the tangential velocity at an end point of each segment is not higher than the deceleration target velocity, and calculates velocity for each second sampling period. A second interpolation section defines a smooth curve based on the output from the acceleration/deceleration control section and the data taken out from the intermediate memory, and outputs a point on the smooth curve for each second sampling period.

A combination of a fastener with an electronic component, wherein the electronic component includes a bobbin having an axial portion, windings around the axial portion of the bobbin, external terminals projecting from the bobbin, around each of which external terminals a termination of one of the windings is coiled, a mold covering the bobbin in a manner to allow portions of the external terminals to be projected outwardly from the mold, the mold being formed of electrically insulating resin material, and a pair of cores assembled to the mold so as to be opposed to each other. The fastener fitted on the electronic component includes a first engaging member engaged in assembly with the cores to clamp the cores, a second engaging member engaged in assembly with a portion of the mold, and an interconnecting member interconnecting the first and second engaging members.

A laser ignition apparatus includes a laser oscillator which generates at least two successive pulse-shaped laser beams during each compression stroke of the engine. A first pulse-shaped laser beam is generated by a Q switching action of the laser oscillator and thus has a high peak output and a second pulse-shaped laser beam is generated without the Q switching action and has a low peak output but a larger pulse duration than the first laser beam. The first and second pulse-shaped laser beams are guided and directed into the combustion chamber of the engine and the first laser beam of a high energy density causes the breakdown of the air-fuel mixture in the combustion chamber to develop a plasma and the second laser beam further increases the energy of the plasma thereby to ensure the setting fire of the air-fuel mixture.
