Abstract: An ink jet head includes an actuator, a driver IC, a first capacitor, a second capacitor, and a fuse. The actuator is configured to cause ink to be discharged from nozzles. The driver IC is configured to drive the actuator. The first capacitor is connected between a ground line and a first node of a power supply line connected to the driver IC. The second capacitor is connected between a ground line and a second node of the power supply line. A capacitance of the second capacitor is less than a capacitance of the first capacitor. The fuse is on the power supply line between the first node and the second node.

Abstract: Devices, systems and methods for regulating the distribution of electricity at events such as trade shows to prevent exhibitors from utilizing electricity not purchased from the convention center or other entity controlling electricity distribution, including lockable electric outlet boxes having a lockable fuse holder containing a fuse that restricts or limits a specific electrical outlet box or group of outlet boxes to a maximum electrical current or amperage.

Abstract: The disclosure relates to an integral electric range surface burner control switch user interface made up of two components. The first component, which controls the burner temperature setting, is a standard knob which is rotated to turn the burner on, as well as set the desired temperature of the particular surface burner. The second component is a timer control ring integrally mounted around the surface burner temperature control knob. The timer control ring is concentric with and has the same central axis as the surface burner temperature control knob, and is rotatable to set the desired cooking time for the particular surface burner. When the selected amount of time expires, the power to the surface burner element is automatically disconnected and the surface burner is disabled, thus requiring a resetting of the timer for further use.

Abstract: In an office machine, in particular in a matrix printer which is provided with a power grid component (3) for the power supply of the electrical or, respectively, the electronic circuits and which includes a safety fuse on the power grid input side, there is disclosed for purposes of more clarity of the construction, for an easier operability and for protection against false connection, that a multiple safety fuse socket (6) for at least two melting safety fuse bodies (9, 10) is coordinated to a voltage selection switch (7). The multiple safety fuse socket (6) can be placed in different relative geometric positions with respect to the voltage selection switch (7) into a fuse socket (8). A selected voltage is coordinated at the voltage selection switch (7) in each position of the multiple safety fuse socket (6).

Abstract: A unit plug which is combined with a voltage selector and a fuse supporting device to form one component is disclosed which has, as a voltage selector, a roller-like pressure hull adjustable in different angular positions and contact pieces movable against the force of springs which, depending upon the angular position of the pressure hull, are held in different combinations by the pressure hull resting against counter-contact pieces assigned to them. The fuse supporting device is provided with at least one exchangeable fuse holder for a fine-wire fuse as well as with contact pieces which rest against the contact caps of the fine-wire fuse when the fuse holder is inserted.
