摘要:
A vibration preventing device is provided with a vibration preventing mode selector capable of selecting a vibration preventing mode in which vibration prevention driving is effected during exposure and a non-vibration preventing mode. Also provided are a vibration prevention start selector for selecting whether vibration prevention control is to be started, and a vibration prevention driving start instructing portion for instructing the start of vibration prevention. Start of vibration prevention driving occurs driving even before the start of exposure when the vibration preventing mode selector selects the vibration preventing mode and the vibration prevention start selector selects the start of the vibration prevention control.

摘要:
Exhaust gas after coal or oil burning has moisture, which hinders carbon dioxide adsorption. It is necessary to completely remove this moisture with the minimum use of energy. The exhaust gas from the burning apparatus is first lowered of its temperature by passing through an total heat exchanger rotor, and the resultant gas which has low temperature and humidity is sent to a carbon dioxide adsorption rotor, thereby removing carbon dioxide from the gas, which is then sent through the total heat exchanger rotor with the resultant desorption of moisture adsorbed there and is exhausted to outside atmosphere, while the carbon dioxide adsorption rotor is desorbed of its carbon dioxide using water vapor, with the resultant very humid carbon dioxide to be sent to a processing system such as for underground burial.

A revolving gas adsorption concentrator uses about 300 degree centigrade of hot desorption air. The revolving gas adsorption concentrator prevents leakage of such hot desorption air. An elastic seal which has elasticity divides a honeycomb shape rotor into a desorption zone and an adsorption zone and touches the honeycomb shape rotor. A heat-resistant seal comprises of material whose heat resistance is higher than elastic seal. The heat-resistant seal has two plates which has a mutually opened spacing to prevent hot gas from going to the elastic seal based on the labyrinth effectiveness. The elastic seal is formed in the outside of desorption zone from heat-resistant seal. The seal of the hot desorption air is almost blocked by heat-resistant seal and the desorption air which leaked slightly can be thoroughly blocked completely by elastic seal.

摘要:
In a cache memory control method and computer of the present invention, a cache memory is connected to a main memory and divided into a plurality of cache blocks, and a lock/unlock signal is supplied to the cache memory to either set a replace-inhibition state of at least one of the cache blocks in which replacing at least one of the cache blocks to the main memory is inhibited, or reset the replace-inhibition state of at least one of the cache clocks such that replacing at least one of the cache block to the main memory is allowed. Either reading or writing of the main memory is performed by using the remaining cache blocks of the cache memory, other than the at least one of the cache blocks, such that, when the replace-inhibition state is set by the lock/unlock signal, replacing the at least one of the cache blocks to the main memory is inhibited during the reading or writing of the main memory.
摘要:
A heat exchanger, perhaps a cross flow heat exchanger, has first and second passages. During dehumidification (adsorption of moisture) in the first passages, water is evaporated from the second passages. This water can be introduced to the second passages during reactivation (desorption of moisture) in the first passages or at another time. If the water is introduced to the second passages during reactivation, the first and second passages have therein first and second moisture adsorbents. During a first time period, air to be dehumidified is passed through the first passages of the heat exchanger and cooling air is passed through the second passages of the heat exchanger to remove heat generated in the first passages and to desorb moisture adsorbed by the second moisture adsorbent. During a second time period, a heating fluid is passed through the second passages of the heat exchanger to heat the first passages and supply moisture for adsorption to the second moisture adsorbent. Also during the second time period, removal air is passed through the first passages of the heat exchanger to eliminate water adsorbed by the first moisture adsorbent during the first time period. If water is introduced to the second passages at a time other than during reactivation, it is not necessary for the second passages to have a moisture adsorbent therein. The water could be introduced to the second passages as a spray during the first time period (during dehumidification).
