Abstract: The present invention provides a pressure sensor module which is capable of restraining application of a pressure of increased magnitude to a connector, reducing the number of parts therefor and compacting a structure thereof. A connector body (3a) is provided on a base section thereof with a flange (3g). An annular support (4) which is made of a material hard to be deformed under a high pressure as compared with the connector body (3a) is provided with an annular engagement recess (4b). The annular support (4) is fitted on the connector body (3a) to engage the flange (3g) with the annular engagement recess (4b). The annular support (4) is contacted on one end surface (4a) thereof with a pressure non-sensing side insulating substrate (5a) of a pressure sensing element (5) outside the base section of the connector body (3a).

Abstract: A novel pharmaceutical use of a dihydropyridine derivative of the formula (I) ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each is an alkyl or the like; R.sub.4 is a hydrogen atom or the like; R.sub.5 is nitro, a halogenated alkyl, cyano or the like; X is a vinylene or an azomethine; A is an alkylene; and B is --N(R.sub.6) (R.sub.7) or a group of the formula ##STR2## wherein R.sub.6 and R.sub.7 are the same or different and each is an alkyl, an aralkyl, an aryl or the like; R.sub.8 and Ar are aryl or the like; and n is 0, 1 or 2, or an acid addition salt thereof for promoting PGI.sub.2 production, and for the treatment and prevention of hyperlipemia, arteriosclerosis and cerebral diseases.
