摘要:
In a process for producing chemical substances comprising steps of cooling, condensing and solvent-absorbing the reaction product gas having a high temperature formed in a reactor, an absorption type refrigerator or an absorption type heat pump is driven by using, as the driving source, a heat source having such a temperature as not to be advantageous for the heat exchange in the process, which heat source has been taken out of the steps of cooling the reaction product gas, condensing it or solvent-absorbing it to obtain a refrigerant or a hot water having a temperature higher than the temperature of the heat source, and the refrigerant or the hot water is used as a cooling source or a heating source in the steps comprised in said process for producing chemical substances.

A partial oxide film (31) with well regions formed therebeneath isolates transistor formation regions in an SOI layer (3) from each other. A p-type well region (11) is formed beneath part of the partial oxide film (31) which isolates NMOS transistors from each other, and an n-type well region (12) is formed beneath part of the partial oxide film (31) which isolates PMOS transistors from each other. The p-type well region (11) and the n-type well region (12) are formed in side-by-side relation beneath part of the partial oxide film (31) which provides isolation between the NMOS and PMOS transistors. A body region is in contact with the well region (11) adjacent thereto. An interconnect layer formed on an interlayer insulation film (4) is electrically connected to the body region through a body contact provided in the interlayer insulation film (4). A semiconductor device having an SOI structure reduces a floating-substrate effect.

A delay correction system is used for a wireless telephone system in which a base station apparatus and at least one subscriber apparatus carry out transmitting and receiving operations via respective communication means, in conformance with a time division multiple access (TDMA) system using the base station apparatus as a synchronization reference. The delay correction system includes a measuring instruction input unit for inputting a delay measuring instruction which instructs a delay measurement, a delay measuring unit for measuring a delay quantity between the base station apparatus and the subscriber apparatus, and a first timing adjusting unit, provided in the subscriber apparatus, for receiving transmitting information which is to be sent to the base station apparatus at an allocated time slot, and for adjusting a timing of the transmitting information depending on the delay quantity before sending the transmitting information.
摘要:
In a semiconductor device having an SOI structure and a method of manufacturing the same, influence by a parasitic transistor can be prevented, and no disadvantage is caused in connection with a manufacturing process. In this semiconductor device, an upper side portion of a semiconductor layer is rounded. Thereby, concentration of an electric field at the upper side portion of the semiconductor layer can be prevented. As a result, lowering of a threshold voltage of a parasitic transistor can be prevented, so that the parasitic transistor does not adversely affect subthreshold characteristics of a regular transistor. Owing to provision of a concavity of a U-shaped section, generation of etching residue can be prevented when etching a gate electrode for patterning the same. Thereby, a disadvantage is not caused in connection with the manufacturing process.

A gear-mesh type automatic transmission system capable of controlling clutch coupling speed so as to mitigate shock likely to occur upon changeover of speed stage regardless of not only time-dependent deterioration of an electromagnetic clutch but also dispersion among individual clutches. The gear-mesh type automatic transmission system includes an electromagnetic clutch (2) for effectuating transmission and interruption of output power from an output shaft (21) of an engine (1) to an input shaft (22) of a gear-mesh type transmission (3), a shift/select actuator (5) for shifting a speed change gear to a shift/select position in the gear-mesh type transmission (3), a shift/select position sensor (6) for detecting a shift/select position of the speed change gear, and a control unit (4) for driving the shift/select actuator (5) in accordance with a shift lever position selected by a driver, to thereby change over automatically the gear-mesh type transmission (3) to a target speed stage. The control unit (4) is designed to couple the electromagnetic clutch (2) while carrying out a feedback control on the basis of a rate of change of rotation speed of the engine (1) in succession to the speed stage changeover.
