摘要:
A process for producing acrolein which comprises bringing a reaction gas resulting from a catalytic oxidation of propylene into contact in a cooling tower with a condensate which is being circulated through the cooling tower and a circulating part, thereby to cool and separate the reaction gas and discharge an effluent gas from the cooling tower, the condensate in a bottom part of the cooling tower having a temperature of from 35.degree. to 50.degree. C., the effluent gas discharged from the cooling tower having a temperature of from 35.degree. to 55.degree. C., the temperature of the effluent gas being kept nearly equal to or higher than the temperature of the condensate in the bottom part of the cooling tower, and a process for producing acrolein which comprises bringing a reaction gas resulting from the catalytic oxidation of propylene into contact in a cooling tower with a condensate which is being circulated through the cooling tower and a circulating part, thereby to cool and separate the reaction gases, the period of the residence time of the condensate in the cooling tower and the circulating part being from 0.5 to 3 hours.

Provided is a wave-power generator capable of adjusting a natural period (natural frequency) in response to a changing wave period. The wave-power generator includes a weight that is installed in a floating body via a spring and that linearly reciprocates in response to a fluctuation of a water surface and a generator that generates power by being driven based on the linear reciprocating motion of the weight. An additional-mass body for adding a mass to the mass of the weight is further included.

A seller's workload of managing credit card information can be reduced without changing convenience for an orderer and the seller in a transaction using a credit card. A virtual mall server (3) and a credit card server (5) share conversion information for obtaining, from actual data of the credit card, corresponding dummy data of the credit card. The virtual mall server (3) obtains, based on the conversion information, the corresponding dummy data from the actual data of the credit card to be used for a settlement of the order information, and sends the obtained dummy data to a shop terminal as data of the credit card to be used for the settlement of the order information. Upon receiving, from the shop terminal, a predetermined card processing request based on the dummy data, the credit card server (5) obtains, based on the conversion information, the corresponding actual data from the dummy data of the credit card, and performs the predetermined card processing based on the obtained actual data of the credit card.
摘要:
A photolithography system has at least one spatial light modulator, a scanning mechanism configured to move an exposure area relative to a target object in a scanning direction, a plurality of memories (1st to Nth memories), a data processor, and exposure controller. The exposure area is defined as a projection area of the spatial light modulator. The plurality of memories corresponds to a plurality of partial exposure areas that is defined by dividing the exposure area. The data processor successively writes exposure data into each memory in accordance with the timing of an exposure, and the exposure controller controls the plurality of light modulating elements on the basis of the relative position of the exposure area. The data processor writes newly generated exposure data into the first memory, and shifts exposure data stored in the 1st to (N−1)st memories to the 2nd to Nth memories, respectively.

The present invention relates to an exposure device for forming predetermined patterns onto an object. The exposure device includes an optical source for emitting a ray, an aperture member including first and second opening windows and a detection window, first and second reflective optical elements for reflecting the first and second light beams that have passed through the first and second opening windows, respectively, and an optical sensor for detecting intensity of the ray from the optical source which has passed through the detection window, the optical sensor being placed close to an area between the first and second reflective optical elements.
摘要:
A data processing apparatus has a first processing unit for processing an input data, a second processing unit responsive to the data processed by the first processing unit for executing a processing dependent on the data and producing a display data, and a display unit having a display drive unit and a display device for displaying the display data. The second processing unit is selectively inactivated and activated under control of the first processing unit to reduce power consumption in the second processing unit. The display drive unit is also selectively inactivated and activated under control of the first processing unit to reduce power consumption in the display unit. The display device has a memory function that maintains its display image even when supply of a display drive signal from the display drive unit is stopped, so that a latest image before inactivation of the second processing unit and/or the display drive unit for power consumption reduction is visible by an operator during the inactivated and low power consumption state of the apparatus.
