Two slide bases (106) synchronizingly traveled on linear guides (105) arranged upwardly and downwardly in parallel with each other are rotatably attached with a clincher unit (107) and a driver unit (104) and provided with a click stop mechanism for fixing the clincher unit (103) and the driver unit (104) at a 0 degree position or a 45 degree rotated position. Respective outer peripheral portion thereof are provided with claw portions (119), (120), in correspondence with the 0 degree position an...

An electric radiator comprising at least one laminar element, at least one electrified flexible sheet being fixed on the face of said element that is not exposed once installed, the sheet being electrically connectable to an electric power source. Elements for fixing to a supporting structure are associated with the at least one laminar element.

An electric screwdriver capable of reducing the reactive force produced on the occasion of a screw tightening work, etc. The electric screwdriver is designed to transmit the rotational driving force of a first motor to the bit through a bit holder, and it includes a flywheel rotatively driven by a second motor in the direction same as the direction of rotation of the bit holder, a brake generating a reactive force in the direction offsetting the reactive force transmitted from the bit to the bod...

A power screwdriver (10) includes a bit holder (14) bored to receive the shaft of a screwdriver bit (12) and adapted to securely hold the screwdriver bit (12) in place, and a housing (18) having a through cavity (16). The bit holder (14) is inserted into the through cavity (16) so that the bit holder (14) is rotatable about and movable along the axis of the bit holder. This arrangement securely holds the screwdriver bit and thus, minimize rattling of the screwdriver bit during rotation.

A transistor has variation in a threshold voltage or mobility due to accumulation of factors such as variation in a gate insulating film which is caused by a difference of a manufacturing process or a substrate to be used and variation in a crystal state of a channel formation region. The present invention provides an electric circuit which is arranged such that both electrodes of a capacitance device can hold a voltage between the gate and the source of a specific transistor. Further, the prese...

An electric lamp has a lamp vessel accommodating an electric element. The element is connected to current conductors including molybdenum portions which have a coating of material chosen from the group of chromium-manganese, chromium-cobalt, chromium-iron and chromium-boron alloys as a protection against oxidation.

In an electric vehicle driven by a drive motor with electric power generated by an engine-driven generator and with electric power from a battery, the electric vehicle includes a residual battery power detecting module for detecting a residual power capacity of the battery, and a motor control module. When the residual power capacity decreases below an established (e.g., preset) lower limit, the motor control module lowers a voltage of an accelerator output signal, which is output in response to...
