摘要:
A method for monitoring a mounting tact of a component mounting apparatus including a component supplier for supplying a component and a component holder for holding the component from the component supplying device and mounting the component onto a circuit board. The method includes collecting and monitoring a mounting tact result value of the component mounting apparatus during a mounting operation via a communication system. The method further includes calculating a tact loss corresponding to an amount by which the mounting tact result value is greater than a standard mounting tact and monitoring the calculated tact loss.

Video picture signals are received via at least three channels. At least three control instructing operators are provided in correspondence with the channels. Each control instructing operator is operable to give a signal control instruction for the corresponding channel in accordance with an operated amount of the operator. Controller performs signal control on the video picture signals of the channels on the basis of the respective signal control instructions given via the control instructing operators. Synthesizer synthesizes the video picture signals of the channels having been subjected to the signal control by the controller. Video picture signals of two desired channels are designated, and a contact-type operator gives signal control instructions, corresponding to a predetermined position of the operator contacted by a human operator, with respect to the video picture signals of the designated two channels. By the signal control instructions, signal control is performed on the video picture signals of the designated two channels to thereby synthesize the video picture signals.
摘要:
The object of the present invention is to provide an apparatus and a method for applying a viscous fluid whereby a constant application diameter is achieved through a simple operation without a Tact loss while a surface of a member to be applied can be less damaged. An adhesive application member (2111) having a screw portion (2122) inserted therein is rotated by a rotating device (230), so that a nozzle stopper (2114) of the adhesive application member is prevented from interfering with a wiring pattern on a face of a circuit board. Moreover, the screw portion is rotated synchronously as well when the adhesive application member is rotated, thereby preventing the adhesive from being discharged out from the nozzle in consequence to the rotation of the adhesive application member. An application diameter can hence be uniformed. The rotation of the screw portion is controlled in accordance with a viscosity of the adhesive, thus achieving the application in a required application diameter through a simple operation.
摘要:
A method and apparatus for applying an electronic component adhesive with a minimum length of time for setting a proper application condition. Variation of application shapes of each type of the adhesive is monitored under various different application conditions and its resultant data is saved. When a desired application shape is inputted, the application nozzles are automatically controlled to apply desired doses of the adhesive under an optimum application condition which is defined by retrieving the data previously stored. Also, various different application shapes for bonding respective electronic components may be determined and saved in advance, so that a proper application condition can be automatically determined by retrieving the data on the application shapes when a desired electronic component is selected.

Disclosed is a method for producing trans-4-aminomethyl cyclohexane-1-carboxylic acid by heating and isomerizing cis-4-aminoethyl cyclohexane-1-carboxylic acid hydrochloride or a mixture of cis-4-aminomethyl cyclohexane-1-carboxylic acid hydrochloride with trans-4-aminomethyl cyclohexane-1-carboxylic acid hydrochloride in an atmosphere of hydrogen chloride gas and in the absence of a solvent.
摘要:
When an engine cooling water temperature (Tw) detected by a cooling water temperature detection means (37C) exceeds a predetermined judgment water temperatures (Tw1 and Tw2) during the forced regeneration control of a filter using exhaust gas temperature raising means (351C), the actuation of the exhaust gas temperature raising means (351C) is interrupted.Thereby, in the case of the exhaust gas purification system having a DPF apparatus (13), it is possible to prevent a water temperature meter in a driver seat from abnormally rising during the forced regeneration of a DPF (13b) and to prevent a driver from taking the abnormal rise of the water temperature meter for an engine trouble.
