This invention provides a serotonin 5-HT3 receptor partial activator which has a serotonin 5-HT3 receptor activating action, in addition to its serotonin 5-HT3 receptor antagonism, and does not cause constipation as a side effect. Particularly, based on the finding that newly synthesized benzoxazole derivatives typified by the compounds of the following formula (2) have strong serotonin 5-HT3 receptor antagonism and serotonin 5-HT3 receptor activating action, this invention provides these benzoxazole derivatives as serotonin 5-HT3 receptor partial activators. In the above formula, R1 to R4 may be the same or different from one another and each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted lower alkenyl group or a substituted or unsubstituted amino group, or two groups of R1 and R2 may be linked together to form a ring structure, namely benzene ring; R5 represents a hydrogen atom, a substituted or unsubstituted lower alkyl group or a substituted or unsubstituted lower alkenyl group; and m is an integer of 1 to 4.

Process and installation for supplying at least one pure active gas to at least one utilization station (P.sub.i) in a first building (A) at a utilization site. It comprises the steps of providing, at the utilization site, a second safety building (B) at a distance from the first building (A), providing at least one source (2; 7; 10) of said gas in the second building (B), and transferring, by at least one safety conduit (C) of high cleanliness, the gas, at a low pressure, to the utilization station (P.sub.i). There is also taught the step of purifying (4; 11) the gas in the second building (B) before transfer to the conduit (C). The pure gas is prepared in situ (2, 4; 10, 11) in the second building (B). There can alternatively be provided, adjacent to the second building (B), at least one source of vector gas (1), with mixing in controlled fashion (6; 9), in the second building (B), the pure active gas with the vector gas before transfer of the mixture to the conduit (C). Apparatus is provided for analyzing (3; 5, 5'; 8, 8'; 12), in the second building (B), the purity and/or the mixing rate of the active gas and/or of a mixture of gas containing the active gas, before transfer to the conduit (C).

There is provided a compression ignition type gasoline engine operable under a stable lean burn condition with a high compression ratio, and which has a simple construction without using a pre-heating system for an air-fuel mixture. An intake port communicates with a combustion chamber via an opening. The opening is closed by an intake valve. A fuel injection valve is provided in the intake port so as to inject an amount of gasoline inside the intake port within a duration in which the opening is substantially closed by the intake valve. Heat is generated in the mixture in the combustion chamber by means of a high compression ratio so that the mixture is self-ignited only by heat generated by compression. The compression ratio ranges from about 14 to about 20.

摘要:
A first gate layer of a first conductor layer is formed on a gate oxide layer and selectively covered with a second gate layer of a second conductor layer. The first and second gate layers are used as a mask and a semiconductor substrate is thermally oxidized to thereby increase a thickness of a portion of the gate oxide layer except the gate layers and cover the second gate layer and the portion having the increased thickness of the gate oxide layer with a third conductor layer. Thereafter, a side wall of an insulating layer is formed on a side portion of the second gate layer and is used as a mask to form a third gate layer. The first, second and third gate layers and the side wall are used as a mask and impurity is introduced into the semiconductor substrate relatively heavily to thereby form a heavily doped impurity layer.

After the formation of SiO.sub.2 films that are field oxide films and P.sup.+ -type diffusion layers that are stopper channels, the Si.sub.3 N.sub.4 films are subjected to an isotropic etching process, thereby removing the regions adjacent to the edges of the SiO.sub.2 films of the Si.sub.3 N.sub.4 films. By using the Si.sub.3 N.sub.4 and SiO.sub.2 films as a mask, N-type impurities are implanted into the Si substrate adjacent to the edges of the SiO.sub.2 films. Then the P.sup.+ -type diffusion layers disappear adjacent to the edges of the SiO.sub.2 films and the P.sup.+ -type diffusion layers are isolated from the N.sup.+ -type diffusion layers, whereby semiconductor devices that are faster and are highly reliable and dependable in operation can be fabricated.

摘要:
Disclosed is a control apparatus for correcting the measurement of flow rates for use with a turbine-type flow meter in which the rotation of a turbine rotating in response to the flow velocity of fluid to be measured is detected to produce pulses which are, in turn, integrated to measure the flow rate of the fluid. The apparatus operates to obtain a value representing the rate of reduction in the flow rate from the pulse cycle in order to detect a first time at which the reduction rate increases above a first predetermined value and a second time at which the reduction rate decreases below a second predetermined value, produce a correction value on the basis of the pulse cycle at the second time and the time lag between the first and second times, and integrate pulses other than those generated in the period of time between the first and second times, adding the correction value from the correction value producing means to the integrated value.
