摘要:
A transverseless ship has at least its side portions and bottom portion comprised of a double hull construction which comprises an inner hull plating and an outer hull plating connected together only by transverse bulkheads and a plurality of longitudinal connecting member fixed to the bulkheads. The bottom portion of the ship has a space defined by at least two optionally selected connecting longitudinal members and divided by two horizontal partitions into two upper chambers and a lower chamber. The upper chambers are adapted to pass different fluids therethrough, and the lower chamber is provided with docking brackets each conforming to the sectional shape thereof. With this structure, external forces acting on the ship are delivered from the connecting longitudinal members to the transverse bulkheads to prevent the inner and outer platings from buckling. The absence of reinforcing transverse members intersecting the connecting longitudinal members assures automatic welding operation with greatly improved efficiency. Since the space within the double hull is utilized to provide fluid channels, there is no need to provide additional fluid transport piping. The docking bracket provided under the fluid channel prevents the bottom portion from deforming when the ship is supported on blocks within a dock.

A transverseless ship has at least its side portions and bottom portion comprised of a double hull construction which comprises an inner hull plating and an outer hull plating connected together only by transverse bulkheads and a plurality of connecting longitudinal members fixed to the bulkheads. The bottom portion of the ship has a space defined by at least two optionally selected connecting longitudinal members and divided by a partition into an upper chamber and a lower chamber. The upper chamber is adapted in its entirety to pass a fluid therethrough. With this structure, external forces acting on the ship are delivered from the connecting longitudinal members to the transverse bulkheads to prevent the inner and outer platings from buckling. The absence of reinforcing transverse members intersecting the connecting longitudinal members assures automatic welding operation with greatly improved efficiency. Since the space defined by the connecting longitudinal members is utilized as a fluid channel, there is no need to provide additional fluid transport piping.

An optical receiver includes: an optical to electric converter that converts a received optical signal into an analog electric signal; an analog to digital converter that converts the analog electric signal obtained by the optical to electric converter into a digital signal; a digital signal processor that performs wave shaping on the digital signal; an information extract circuit that extracts information related to loss or deterioration of the optical signal from a signal propagating from the analog to digital converter to the digital signal processor or a signal in the digital signal processor; and a judging circuit that judges, based on the information extracted by the information extract circuit, whether the optical signal is lost or deteriorates.

In a laser processing system 400, a plurality of element patterns for creating a modulation pattern are prepared, and the modulation pattern is created from the element patterns according to a condition for forming the modified region for an object to be processed in order to form the modified region corresponding thereto. Laser light is modulated according to thus created modulation pattern, and the modified region is formed in the object by irradiation with the modulated laser light. Thus, according to the condition for forming the modified region corresponding to the object, the modulation pattern is created from the element patterns prepared beforehand.

A method of cutting an object to be processed is provided, which can accurately cut an object to be processed comprising a substrate and a multilayer part provided on the front face of the substrate while having a plurality of functional devices into the functional devices along a line to cut in a short time even when the substrate is thick. A substrate 4 is irradiated with laser light L from the multilayer part 16 side while locating a converging point P within the substrate 4, so as to form a first modified region 71 shifted from the center position CL in the thickness direction of the substrate 4 to the rear face 21 side of the substrate 4 and a second modified region 72 shifted from the center position CL in the thickness direction of the substrate 4 to the front face 3 side of the substrate 4 within the substrate 4 along a line to cut, and generate a fracture 24 from the second modified region 72 to the front face 3 of the substrate 4. Thereafter, while in a state where an expandable tape 23 attached to the rear face 21 of the substrate 4 is expanded, a stress is generated in an object to be processed 1 such as to open the fracture 24.

A method of cutting an object to be processed comprises the steps of irradiating an object to be processed with a laser light which is an elliptically-polarized light having an ellipticity other than 1 such that a direction of polarization of the laser light intersects a line to cut the object and a thickness direction of the object, while locating a converging point of the laser light within the object, so as to form a modified region within the object along the line and generate a fracture from the modified region in the thickness direction of the object, and causing the fracture to reach front and rear faces of the object so as to cut the object along the line.

An engine start control apparatus enables a user to start an engine of a vehicle irrespective of a user's operation of ignition key. The engine start control apparatus includes a controller that performs engine start control and a storage unit. When the engine abnormally stops during a period in which the controller performs the engine start control, the storage unit stores at least one of a cause of the abnormal stop and a timing of the abnormal stop.

A laser processing method is provided, which, even when a substrate formed with a laminate part including a plurality of functional devices is thick, can cut the substrate and laminate part with a high precision.This laser processing method irradiates a substrate 4 with laser light L while using a rear face 21 as a laser light entrance surface and locating a light-converging point P within the substrate 4, so as to form modified regions 71, 72, 73 within the substrate 4. Here, the quality modified region 71 is formed at a position where the distance between the front face 3 of the substrate 4 and the end part of the quality modified region 71 on the front face side is 5 μm to 15 μm. When the quality modified region 71 is formed at such a position, a laminate part 16 (constituted by interlayer insulating films 17a, 17b here) formed on the front face 3 of the substrate 4 is also cut along a line to cut with a high precision together with the substrate 4.
