摘要： An electromagnetically driven transport device 1 includes a transport unit 4 for transporting an article M to be transported, an electromagnetically driven vibrating unit 2 for vibrating the transport unit 1 to transport the article, a frequency controlling unit 14, a time detecting unit 15 and a frequency setting unit 16. The frequency controlling unit 14 controls a driving frequency of a driving power source 13 of the vibrating unit 2. The time detecting unit 15 detects a time length T during which when the driving frequency is changed the driving current of the vibrating unit at each of frequency exceeds a reference current value. The frequency setting unit 16 is operable to set an actual driving frequency based on the time length T detected by the time detecting unit 15.

摘要： A heat sealer capable of providing a high sealing strength by appropriating a distribution of temperature at two sheet contact faces (19a, 19b) includes a block (31) made of a metallic material having a high rigidity and operable to heat the resinous sheet (S) while pressing the latter. The block (31) is provided with heaters (24a, 24b) therein and also with heat conducting members (33a, 33b) each having an excellent heat conductive characteristic higher than that of the metallic material. The heat conducting members (33a, 33b) are positioned between the heaters (24a, 24b) and the sheet contact faces (19a, 19b), respectively.

摘要： A plurality of trough displacement characteristics and drive signals for driving a drive unit 26 for a trough 25 are determined in association with each other and the speed of transport of the articles M transported by the trough 25 having one of the trough displacement characteristics is also determined. Accordingly, a plurality of relationships between the transport speed of the articles M and the drive signal of the drive unit 26 can be determined and, based on these relationships and merely by inputting a target speed to be attained by the articles M, the drive signal for the drive unit 26 can easily be selected which enables the speed of transport of the articles M to attain the target speed. Also, since a travel quantity characteristics indicative of a correspondence between the quantity of travel of the articles and the driving time of the trough 25 with respect to each of parameters of the plural coefficients of kinetic friction &mgr; is determined, the quantity of travel of the articles M with respect to the driving time of the trough 25 can be grasped with respect to the plural coefficients of kinetic friction &mgr; taken as a parameter. Based on this, the coefficient of kinetic friction &mgr; between the desired trough 25 and the articles M can easily be obtained from the quantity of travel of the articles measured by actually driving the trough 25 for a predetermined time to transport the article M.
