A paper transportation control method for an apparatus enables conveying paper with appropriate tension on the paper by appropriately controlling the paper delivery operation of a delivery roller. When paper is conveyed by the paper feed roller pair 34 of a roll paper printer 1, and the tension on the paper 8a is detected to exceed an upper tension limit based on the displacement of a damping mechanism 32 (time t2), the paper delivery operation of a delivery roller pair 33 starts at a time t3 after a start operation delay time DLS (first delay time) corresponding to the feed rate V(34) passes after time t2. When the tension returns to or below the upper tension limit, the paper delivery operation stops at a time t5 after a stop operation delay time DLE (second delay time) similarly corresponding to the feed rate V(34) passes. Tension fluctuation (change in the load on the paper feed roller) can be controlled without causing chattering or fluttering in paper delivery operation control.

Disclosed herein is mobile middleware, a context monitoring method, a context-aware system, and a context-aware service provision method, which support energy-efficient context monitoring. The mobile middleware receives a request for a CMQ from context-aware application programs, receives sensor data from sensors, monitors whether the CMQ is satisfied, and transmits an event to the context-aware application programs according to results of the monitoring. In this case, the mobile middleware controls the sensors so that only sensor data required to determine whether the CMQ is satisfied needs to be transmitted so as to reduce energy consumption during the performance of the monitoring. Therefore, the mobile middleware can perform energy-efficient context monitoring, required by the context-aware application programs.

A chemical solution is uniformly dispensed from a nozzle by N₂ in spin-coating equipment. The dispensing apparatus includes a canister configured to receive a bottle containing the chemical solution, gas supply piping connecting a source of N₂ to the inside of the canister, a pressure control valve disposed in the gas supply piping, a chemical supply line by which the bottle is connected to the nozzle, a pressure sensor for sensing the pressure of the chemical solution supplied from the bottle, and a controller that controls the pressure control valve on the basis of the pressure sensed by the pressure sensor. The controller opens the pressure control valve further when the value of the signal output by the pressure sensor is less than a value representative of the minimum of a predetermined pressure range, and closes the pressure control valve further when the value of the signal output by the pressure sensor is greater than a value representative of the maximum of the predetermined pressure range. The degree to which the pressure control is open is thus controlled by feedback from the pressure control sensor such that the pressure of the chemical solution remains substantially constant as it is dispensed from the nozzle.

A hydrocarbon fuel is either imperfectly combusted or thermally decomposed in a reactor 11, thereby producing a high-temperature gas flow containing fullerenes and soot. A mixture of the fullerenes and soot is collected from the gas flow using a filtering unit 12 which includes a heat-resistant filtering member made of either a porous ceramic material or a porous metal material. The fullerenes are collected from the mixture by usual means. These processes according to the method of the present invention make it possible to produce a large amount of fullerenes.

In a hybrid vehicle, once an engine is started in response to prohibition of an operation stop of the engine based on a deterioration factor, the operation stop of the engine is not allowed irrespective of the value of the deterioration factor D until elapse of a certain time period since the start of the engine. The deterioration factor has an increase according to discharge of a battery and a decrease according to charge of the battery and represents start of deterioration of the battery when exceeding a specific reference value. Such prohibition of the engine operation stop prevents a stop of the engine within a relatively short time period after a start of the engine based on the deterioration factor. This arrangement effectively prevents the driver from feeling odd and uncomfortable due to frequent stops and starts of the engine based on the deterioration factor, which is not apparently correlated to the driver's accelerating operations.
