Abstract: The present invention provides a cutoff valve control apparatus capable of predicting a failure of devices therein with a failure diagnosis based on an operation test when the cutoff valve control apparatus is set. The cutoff valve control apparatus includes a judging device to judge a normal state or an abnormal state of the apparatus based on a pressure characteristic of an internal pressure of a cylinder measured with a pressure sensor when an air is supplied to the cylinder of an air cylinder from an air supply source, and a memory device storing beforehand the pressure characteristic of the internal pressure of the cylinder of an initial normal operation of the apparatus and the pressure characteristic of a failure prediction boundary.

Abstract: In a conventional operating handle for an operating machine, the two ends of a vibration-proof rubber are sandwiched between a handle rod and a grip bar, thereby connecting the handle rod and grip bar. The vibration of the handle rod is absorbed by the torsion of the vibration-proof rubber. As a result, the vibration of the handle rod can only be reduced rather than eliminated. In the present invention, a grip bar is attached rotatably to the upper end of a handle rod so as to be capable of a rocking motion, and the swing shock generated when the grip bar oscillates is absorbed by a stopper rubber provided on the handle rod. Thus the vibration of the grip bar can be absorbed efficiently by the rockable rotatably attached portion and the stopper rubber.

Abstract: A vibrating plate compactor having a vibration generator, a water tank, wherein the water tank is removably mounted on the compactor. The compactor includes a sprinkler pipe having a nozzle, a connection pipe having a switch cock and a pair of brackets projecting downward from both sides of the front of the tank. Two ends of the sprinkler pipe are connected between the brackets. A recess portion projects below the tank bottom at one part thereof at the rear of one of the brackets. The recess portion and one of the brackets are connected by the connection pipe having the switch cock.

Abstract: There is provided an apparatus for supplying an ice water-containing bag for use in icing. The apparatus includes an ice machine, an ice storing section for storing ice manufactured by the ice machine, ice packing means for packing the ice stored in the ice storing section in a bag having a water resistance, water supplying means for supplying water into the bag, sealing means for sealing an opening of the bag in which ice and water has been put, a belt conveyer for carrying the bag containing ice and water, a controller for controlling the respective means to be activated/suspended, and ice-water manufacturing instructing means connected with the control means, for sending an instruction for manufacturing the ice water-containing bag.

Abstract: A vasodilating or anti-hypertensive composition comprises a pharmaceutical carrier and an effective amount of a 1,4-dihydropyridine compound as an active ingredient. The 1,4-dihydropyridine compound may be represented by the following general formula: ##STR1## wherein R'.sub.1 and R'.sub.4 represent a hydrogen atom, R'.sub.2 and R'.sub.3 represent an alkyl group having 1-5 carbon atoms or a substituted heterocyclic group wherein a substituent is an N-benzylpiperidyl group, R'.sub.5 represents a nitro group, and R'.sub.6 and R'.sub.7 represent an alkyl group having 1-5 carbon atoms.

Abstract: Compounds having coronary and vasodilator effects, a hypotensive effect, and useful as antianginal drugs and drugs for treating hypertension are represented by the following general formula: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different groups and each represents a lower alkyl group, one of R.sub.3 and R.sub.4 represents a lower alkyl group and the other represents a group of the general formula: ##STR2## wherein R.sub.5 represents an aralkyl group or an acyl group and n represents 0 or an integer of 1-3; the pharmaceutically acceptable acid addition salts thereof are also effective therapeutic compounds.
