In a single can-type composite heat source machine including a single can body (2) including a first combustion section (3-1) having a first burner (4-1) and a hot water supplying first main heat exchanger (5-1) located above the first burner (4-1), and a second combustion section (3-2) having a second burner (4-2) and a second main heat exchanger (5-2) located above the second burner (4-2) and used for a purpose other than hot water supply, the first combustion section (3-1) and the second combustion section (3-2) being partitioned from each other by a partition wall (2a) and juxtaposed in a lateral direction, the machine including a first auxiliary heat exchanger (11-1) and a second auxiliary heat exchanger (11-2) both of a latent heat recovery type connected to upstream sides of the first main heat exchanger and the second main heat exchanger, respectively, an exhaust system can be miniaturized and simplified in spite of provision of the auxiliary heat exchangers. A space in an exhaust hood (9) common to both the combustion sections (3-1, 3-2) arranged on the can body (2) is partitioned by a partition wall (9c) into a first exhaust space (10-1) and a second exhaust space (10-2) through which exhaust gases from the first and second burners (4-1, 4-2) flow, respectively. The first and second auxiliary heat exchangers (11-1, 11-2), each composed of laterally meandering heat absorbing tubes (11a), are arranged in the respective exhaust spaces.

A fuel cell stack includes a plurality of unit cells stacked together. End cell stacks are disposed at opposite ends of the unit cells in the stacking direction. The unit cells between the end cell stacks are electrically connected in series. A first unit cell and a second unit cell in each of the end cell stacks are electrically connected in parallel by a cable. In each of the first and second unit cells a membrane electrode assembly is interposed between a first separator, and a second separator.

According to the present invention, access to a password area in a nonvolatile memory cannot be granted by simple supply of an address in a normal order. According to one preferable mode, for instance, a trap address is set in the password area so that reading information from the password area is permitted only when the password area is accessed without accessing the trap address, whereas when the password area is accessed the trap address, whereas when the password area is access through the trap address, information reading is inhibited, or meaningless data is output or the information in the password area is destroyed. This invention can make it harder to gain access to a password area which is used to protect against illegitimate copying and can provide a nonvolatile memory having a stronger copy protection capability.

A method of producing a single crystal by Czochralski method by contacting a seed crystal with a melt in a crucible, and then pulling it slowly to grow a single crystal ingot, wherein a pulling condition is controlled according to a cumulative time of use of a heater surrounding the crucible. The pulling conditions to be controlled may induce the relative position of the heater and the crucible, the number of rotations of the crucible, the number of rotations of the crystal, or an atmosphere pressure in the furnace and a gas volume of flowing. Also described is a method of producing a silicon single crystal by CZ method wherein a dispersion of impurity concentration in the crystal can be reduced, and a single crystal can be produced stably.

In a method of making a gas burner device, there are steps of symmetrically blanking a first metal plate and deforming it so as to form a first intermediate blank having a bulged portion, bending the first intermediate blank at a symmetrical center thereof to provide a first burner flow path with the bulged portion, and joining end portions of the intermediate blank to form a first burner, blanking a second metal plate and symmetrically deforming it so as to form a second intermediate blank having a bulged portion, bending the second intermediate blank at a symmetrical center thereof to provide a cover plate; and encasing at least an upper end of the first burner with the cover plate to form a slit-like sleeve first hole between the first burner and the cover plate, and forming a second burner flow path communication with a second burner suction hole and the slit-like sleeve fire hole so as to provide a second burner.
摘要:
In a gas burner device having a first burner having a first fire hole formed therein and a second burner having a second fire hole arranged therein, the fire hole is disposed around the first fire hole of a first burner to straddle the first fire hole. The second burner has a common suction hole through which a fuel gas and primary air are supplied to the second fire hole independent of fuel gas and primary air supplied to the first burner.

A fuel cell stack is comprised of a plurality of power generating units which are stacked along the horizontal direction. A corrugated passage groove having a shape corresponding to the shape of the underside surface of a corrugated passage groove of a first fuel gas passage is formed in a surface of a first metal separator. A corrugated passage groove having a shape corresponding to the shape of the underside surface of a corrugated passage groove of a second oxidant gas passage is formed in a surface of a third metal separator. The corrugated passage grooves overlap one another to define a refrigerant passage. An oxidant gas inlet port and a fuel gas inlet port are provided in the upper portion of the power generating unit, and an oxidant gas outlet port and a fuel gas outlet port are provided in the lower portion of the power generating unit. A refrigerant inlet port and a refrigerant outlet port are formed in each of the left and right portions of the power generating unit.
