Abstract:
A fuel reforming apparatus is provided for generating a hydrogen-rich gas. The fuel reforming apparatus includes an evaporator comprising an evaporation chamber for evaporating the fuel vapor by evaporating a hydrocarbon fuel-water mixture by an evaporator using a combustion gas formed in a combustor; a heating chamber for heating the fuel vapor by a combustion gas output from the evaporation chamber; and a guiding path for guiding the combustion gas output from the evaporation chamber to the heating chamber along the floor of the evaporating room. In the heating chamber, the fuel vapor generated in the evaporation chamber is uniformly heated in an atmosphere with a homogeneous temperature of the combustion gas output from a heating medium tube, while the fuel vapor is circulating in the vapor tube.
Abstract:
A process for brazing a die-cast aluminum material, wherein a die-cast aluminum material produced at a gate speed of 20 m/s or higher is used to be brazed at a brazing temperature of 500.degree. C. or lower. Further, it is preferred that the die-cast aluminum material is produced under a casting pressure of 600 kgf/cm.sup.2 or lower, or that the die-cast aluminum material is produced while depressurizing a mold. Brazing may as well be conducted using a brazing filler metal material composed of 6 to 24 wt. % of Al and the balance consisting of Zn and impurities. In the foregoing manner, the die-cast aluminum material can be brazed by heating it to a high temperature.
Abstract:
Transmission, speed at which data is transmitted over a digital transmission line between a transmission device and a remote device, is set by transmitting an inquiry command to the remote device at a predetermined transmission speed; receiving, from the remote device, a response to the inquiry command; determining based on the content of the response any transmission speeds common between the remote device and the transmission device; and setting transmission speed at which transmission between the transmission device and a remote device is to be performed to one of the transmission speeds common between the remote device and the transmission device.

Abstract:
The disclosed is a cleaning sheet comprising second microcapsules, which encapsulate a solvent dissolvable of a photo-curable material, so that any radiation curable material sticking to a surface of a pressure roller member of a transfer imaging system will be efficiently cleaned away, thereby maintaining a constantly smooth surface of the pressure member which can then apply pressure onto the photo-pressure sensitive sheet uniformly, resulting in a unblemished transmittance of the original image.

According to an embodiment, an induction heating coil includes a heating conductor portion which is formed of a conductor member and has a zigzag shape in which a bent portion opened to one side in a first direction and a bent portion opened to the other side in the first direction are alternately continuously arranged in opposite directions along a second direction crossing the first direction.
Abstract:
The silicon nitride layer 910 formed by plasma CVD using a gas containing a hydrogen compound such as silane (SiH4) and ammonia (NH3) is provided on and in direct contact with the oxide semiconductor layer 905 used for the resistor 354, and the silicon nitride layer 910 is provided over the oxide semiconductor layer 906 used for the thin film transistor 355 with the silicon oxide layer 909 serving as a barrier layer interposed therebetween. Therefore, a higher concentration of hydrogen is introduced into the oxide semiconductor layer 905 than into the oxide semiconductor layer 906. As a result, the resistance of the oxide semiconductor layer 905 used for the resistor 354 is made lower than that of the oxide semiconductor layer 906 used for the thin film transistor 355.

Abstract:
A semiconductor device fabrication method in which when a semiconductor device with a built-in light receiving element is fabricated, a section for dividing the light receiving element is protected from damage caused by, for example, etching. An antireflection coating is formed not only on a light receiving area in a divided photodiode area but on a division area including a junction area between a division section outside the light receiving area for dividing a photodiode and a cathode. A polycrystalline silicon film is formed so as to cover the antireflection coating. Accordingly, the antireflection coating on the junction area between the division section outside the light receiving area and the cathode is protected against, for example, etching by the polycrystalline silicon film. As a result, the appearance of a crystal defect, a change in impurity concentration, or the like is suppressed in this area. Therefore, a high-performance high-quality semiconductor device with a built-in photodiode can be fabricated.
