In a photoresist pattern formation by exposure using first and second photomasks, the first photomask has a transparent part, a rectangular opaque part having a first pair of sides and a second pair of sides, and a phase shifter, having a first edge crossing one of the first pair of sides, so that a part of the first edge is in the transparent part, and the second photomask has a transparent part, a rectangular opaque part corresponding to the rectangular opaque part of the first photomask, and a stripe-shaped opaque part corresponding to the first part of the first edge of the phase shifter. The rectangular opaque part of the first photomask is expanded in the direction of the first pair of sides, while the rectangular opaque part of the second photomask is expanded in the direction the second pair of sides. The amount of expansion is preferably not smaller than a misalignment tolerance.

A water heater in which by applying pulsation of a liquid to be heated which circulates between a tank and a heat exchanger, scale that has been deposited on the inner wall (heat-transfer surface) of a to-be-heated liquid flow channel in a heat exchanger is detached, and the number of times of circulation of the liquid to be heated which circulates between the tank and the heat exchanger is controlled to be three times or less. The number of times of circulation is determined, based on the entire volume of the to-be-heated liquid stored in the tank, a boiling time to be taken for the entire volume of the to-be-heated liquid in the tank to reach a predetermined temperature, and the flow rate of the to-be-heated liquid which passes through the to-be-heated liquid flow channel.

To improve the separation efficiency of a gas-liquid separator in the gas-liquid separator and an air conditioner, the gas-liquid separator having a vessel with an inlet pipe and an outlet pipe is arranged such that an exit end section of the inlet pipe is formed to be closed or to have a gap, an expanded end section having a width greater than the diameter of that portion of the inlet pipe which crosses a container of the gas-liquid separator is provided, and that a lateral hole is formed in a side face of the expanded end section. Refrigerant vapor and refrigerant liquid are efficiently separated from each other at the expanded end section, and this improves separation efficiency of the gas-liquid separator.

A bag formed of a sheet material adapted to be filled with contents and opened at the top for taking out the contents. The bag has fused joints along the lateral edges thereof. A plastically deformable wire-like member is attached inside the fused joints over a length from the output opening side portion to the body portion.
摘要:
A heat exchanger including plate fins and, the tubes fins being stacked at respective intervals relative to one another, and heat exchanger tubes penetrating the fins in a fin-stacking direction. The heat exchanger exchanges heat between fluids flowing, respectively, inside and outside the heat exchanger tubes, through the heat exchanger tubes and the fins. Each of the fins includes cut-raised portions with a bridge shape having leg and beam segments. The cut-raised portions associated with each of the heat exchanger tubes are located substantially only in a region of the fin satisfying Ws=(1−φ)Dp+φD φ>0.5, where Ws is spread width of the cut-raised portions in a direction (column direction) extending along an end of the fin on the upstream side of the second fluid, and D is outer diameter of the heat exchanger tube. Dp is alignment pitch of the heat exchanger tubes in the column direction.

A business management method, a business management apparatus and a data broadcast delivery method are disclosed which allows contents to be broadcast over an unused bandwidth in satellite broadcasting so that the contents are stored and later reproduced as needed for quick access to a desired destination recorded in the contents. A data broadcast is assigned to an unused broadcast bandwidth over a broadcast band for transmitting programs in satellite broadcasting. The data broadcast over the unused bandwidth are stored onto a storage medium in a TV set. The stored data contents are sorted out by category for selective viewing by operation of the TV set. If the selected content offers e-commerce, a virtual shop handing desired offerings is accessed as per the content.

A telephone 12a connected to a local area network 10, comprising a means for requesting during communication a response from another receiver-side telephone 12b indicating its availability to receive a call, and a means for notifying the address of the receiver-side telephone 12b that responded to the caller-side telephone 22a.
摘要:
A semiconductor device includes a Schottky layer, a cap layer covering the surface of the Schottky layer, and a Schottky electrode of a two-level structure. The Schottky electrode has a lower portion that penetrates through the cap layer and reaches the Schottky layer, and has an upper portion larger than the lower portion in cross-sectional area and that overlies the cap layer. With this construction, surface defects are unlikely to occur, so that a highly reliable semiconductor device can be fabricated.
