It relates to equipment and a process for producing carbonated water of a high-concentration inexpensively and easily. Since the equipment for producing the carbonated water and the process for producing the carbonated water using a static mixer having 20 to 100 elements realize production of the carbonated water of the high-concentration inexpensively and easily, they can be applied particularly effectively for so-called one pass production process. Moreover, the carbonated water of a higher concentration can be produced further effectively by providing a value Re×N of 100,000 to 2,000,000, wherein N is a number of elements of the static mixer and Re is a Reynolds number when a mixture of water and a carbonic acid gas flow in the static mixer.

A commodity information display apparatus includes a shelf on which a commodity is displayed, and a display unit for displaying the commodity information about the commodity. The commodity information about the commodity related to an RFID tag detected by an antenna and a read device is acquired in advance from a store computer and stored in a storage unit. When the commodity information is displayed, the information is acquired from the storage unit, and displayed on the display unit.

An inner cutter for a dry shaver has a plurality of blades 30 supported on a base 20 and is driven in hair-shearing engagement with an outer cutter 10 for cutting the hairs. The blades 30 are arranged in parallel with each other and are each provided on opposite sides at its top with cutting edges 32. The cutting edge 32 is defined between the top face of the blade and a rake fade 33 on the underside of the blade. The rake face 33 is inclined with respect to the top face at an angle of α (°), while the cutting edge is rounded at its tip to have a curvature radius R (μm) which satisfies a relation that R≧−0.067·α+4.7. With this result, the cutting resistance for cutting the hair can be lowered below a load necessary for bending the hair. Thus, the blade of the inner cutter can itself cut the hair without bending the hair, giving a flat cutting plane finish and enabling a close shave only with a fewer shaving strokes.

An exhaust gas recirculation device of an engine (10) of the invention comprises a first exhaust gas recirculation passage (50) for connecting an exhaust passage (40) and an intake passage (30) to each other and introducing into the intake passage an exhaust gas discharged from a combustion chamber (21) to the exhaust passage, and a second exhaust gas recirculation passage (55) for connecting the exhaust passage upstream of a part of the exhaust passage connected to the first exhaust gas recirculation passage and the intake passage downstream of a part of the intake passage connected to the first exhaust gas recirculation passage to each other and introducing into the intake passage the exhaust gas discharged from the combustion chamber to the exhaust passage. The amount of the exhaust gas introduced into the intake passage via the first exhaust gas recirculation passage is controlled to a first target exhaust gas recirculation amount and the amount of the exhaust gas introduced into the intake passage via the second exhaust gas recirculation passage is controlled to a second target exhaust gas recirculation amount. When a temperature of the flame on the combustion of a fuel is lower than or equal to an allowable upper limit flame temperature, a first reference exhaust gas recirculation amount set depending on the operation condition of the engine, is set as the first target exhaust gas recirculation amount and a second reference exhaust gas recirculation amount set depending on the operation condition of the engine, is set as the second target exhaust gas recirculation amount. When the temperature of the flame on the combustion of the fuel is higher than the allowable upper limit flame temperature, one of the first reference exhaust gas recirculation gas amount and an amount smaller than the first reference exhaust gas recirculation gas amount is set as the first target exhaust gas recirculation amount and an amount larger than the reference second exhaust gas recirculation amount is set as the second target exhaust gas recirculation amount.
摘要:
In a server-client type system, when a large volume of data to be transmitted whose volume is not less than a predetermined value is generated, a server notifies to a terminal device as a transmission destination to the effect that the large volume of data is to be transmitted by the D-channel packet exchange, and after receiving a data transmission timing signal from the terminal device, starts transmission of the large volume of data using a B-channel to cause the terminal device to download the large volume of data, and the terminal device monitors a state of a free B-channel line in all ISDN communication devices on the client side connected to the same digital service unit upon receiving the notification of transmission of the large volume of data from the server and notifies the server of the data transmission timing signal by the D-channel packet exchange at timing not preventing use of a B-channel line.
