Abstract: A mark forming method includes: forming recessed portion on a mark formation area of a substrate; coating the recessed portion with a polymer layer containing a block copolymer, allowing the polymer layer in the recessed portion to form a self-assembled area; selectively removing a portion of the self-assembled area; and forming a positioning mark by using the self-assembled area from which the portion thereof has been removed.

Abstract: A mark forming method includes: exposing a wafer with a mask image to form first and second resist marks that have different shapes than one another based on a portion of the mask image; applying a polymer layer that contains a block copolymer to the wafer by spin-coating; forming self-assembled regions in the applied polymer layer; selectively removing a portion of the self-assembled regions; and forming first and second wafer marks on the wafer using the first and second resist marks. This makes it possible to form the marks when forming circuit patterns using self-assembly of a block copolymer.

Abstract: An electromagnetic contactor includes a contact mechanism including a pair of fixed contacts having fixed contact portions and interposed in a current conduction path, and a movable contact having a pair of movable contact portions capable of contacting to and separating from the pair of fixed contact portions. At least one of the pair of fixed contacts or the movable contact is formed in a shape to form magnetic fields generating Lorentz forces opposing electromagnetic repulsion forces generated in an opening direction between the fixed contact portions and the movable contact portions when current is conducted. External connection conductors are connected to external connection terminals of the fixed contacts, an attachment direction of fixed portions fixed to the external connection terminal of the fixed contacts is set to cross a current flow direction flowing through the movable contact.

Abstract: Provided is a configuration which prevents an engine from being unable to start in the state in which dew condensation occurred in a fuel injection pump and froze. The present invention relates to a fuel injection pump which is provided with a pump body and a hydraulic head and driven by an engine, and is characterized in that while the engine is in operation, the temperature of the hydraulic head is increased to a dew-point temperature or higher. Consequently, it is possible to increase the temperature of the hydraulic head and remove water in the fuel injection pump while the engine is in operation. Accordingly, the engine can be prevented from being unable to start in the state that dew condensation occurred in the fuel injection pump and froze.

The movable contact is disposed so as to be connectable to and detachable from the pair of fixed contacts disposed to maintain a predetermined interval inside a contact housing case having insulating properties, and an arc extinguishing chamber is formed in a position in which the movable contact and the pair of fixed contacts contact. At least the inner wall surface side of the arc extinguishing chamber contacting an arc is formed of a high thermal conductivity material having thermal conductivity higher than that of a synthetic resin molded material.
