Abstract: A lifting implement for removing a panel (10) which has a receiving means (18) in the body of the said panel (10) on the surface of the panel (10) which is exposed in use, the receiving means (18) being offset from the center of the panel (10), from a position in which it is held by gravity in an aperture (12) defined by a surrounding floor or ground surface (14) where the exposed surface of the panel (10) is substantially flush with the surrounding surface (14) comprises a handle (41) with an elongate shift (43) for use by an operator in a standing position, terminating in an engagement member (42) engageable with said receiving means (18), wherein the handle (41) is connected to the engagement member (42) by pivotable means (50), whereby said panel (10) can be removed from said aperture (12), and said handle (41) can move relative to said engagement member (42) during the removal of the panel (10) from the aperture (12), the lifting implement being further provided with restricting means (60) which is movab

Abstract: The present invention relates to a structure of a rotor for a brushless motor which can improve structural stiffness, restrict noise generation by reducing vibration during the rotation, use cheap materials, reduce a fabrication cost by fabricating a back yoke and a base plate unit in a single body. improve durability, and efficiently cool a heat generated in the motor during the operation by facilitating an external air inflow.

Abstract: A high-frequency module which includes a dielectric resonator defined by a dielectric sheet; a pair of electrodes formed on each of the main surfaces of the dielectric sheet and having aligned openings which form a dielectric resonator; a substrate stacked on the sheet; and lines disposed on the substrate for being coupled to the dielectric resonator. At least one of the lines is curved and is disposed just inside the opening and runs substantially along the edges of the openings.

Abstract: An inkjet recording apparatus includes K ejection electrodes and M counter electrodes which are located at a distance from and opposed to the K ejection electrodes. A first voltage pulse is applied to a selected one of N groups of ejection electrodes each group formed by electrically connecting an i.sup.th (1.ltoreq.i.ltoreq.N) ejection electrode for each counter electrode to each other and a second voltage pulse is applied to a selected one of the M counter electrodes. A voltage difference is generated between a group and a counter electrode which are selected from the N groups and the M counter electrodes depending on an input signal, wherein the voltage difference is equal to or greater than a minimum voltage difference which causes ejection of ink from an ejection electrode.

Abstract: An optical unit coupling mechanism for coupling optical units 10, 11 having a plurality of mutually parallel optical paths 10a, 10b with each other, said optical unit coupling mechanism comprising a round dovetail consisting of a male dovetail 1 and a female dovetail 4, wherein said male dovetail 1 has a minor diameter part 1b of predetermined diameter d.sub.2, part 1d of which is sized larger than the diameter d.sub.2 of the minor diameter part 1b. By virtue of this optical unit coupling mechanism, the system performance can be enhanced without causing a system enlargement and the system compatibility can be maintained.

Abstract: A method of insulating a heated surface comprising enveloping the surface by a first layer of a heat insulating material having a high thermal resistivity such as Mineral Wool, and enveloping the first layer by a second layer of a material having a lower thermal resistivity, such as Polyurethane.

Abstract: In DDC1, a data request signal is applied to overlap a vertical synchronization signal from a computer 1 to a terminal 33, the data request signal is applied from a receiver 24 through a switch 25 to a non-volatile memory 27, information related to a video monitor 4 is read from the non-volatile memory 27, and the read information is applied from a driver 21 through a data terminal 31 to the computer 1. In DDC2B, a data request signal is applied to both the data terminal 31 and a clock terminal 32, a part of the data request signal is decoded by a data request decoder 28 through a receiver 22, the data request signal is applied through the switch 25 to the non-volatile memory 27, information is read from the non-volatile memory 27, and the read information is applied from the driver 21 through the data terminal 31 to the computer 1.
