There is provided a drive device for a vehicle. A forward clutch that is engaged during forward driving is provided in a power transmission path between an engine and a drive wheel. A spring is incorporated in an engagement oil chamber of the forward clutch, thereby causing the forward clutch to be held in a slipping state or an engaged state through the spring force even during an idling stop that suffers from reduced control oil pressure. This arrangement can prevent the forward clutch from producing an engagement shock during an engine restart. In addition, an input clutch driven by an electric actuator is provided in the power transmission path. With this arrangement, neutral control can be performed by disengaging the input clutch even if the forward clutch which is to be held in a slipping state or an engaged state is provided.

The invention aims to provide a novel alkaline protease having peculiar properties such as high alkali activity, resistance to surfactants and calcium-dependent thermostability and exhibiting excellent performance in highly alkaline detergents, and a gene coding for the amino acid sequence thereof. There is provided an alkaline protease with such properties that an active pH range is from 5 to 13, an optimum pH is approximately 12.6, an optimum temperature is 70° C., no activity drop by heating is observed up to 65° C. at pH 10 and the optimum temperature and the thermostability are not affected by Ca2+ ions. Specifically, there is provided, for example, an alkaline protease having an amino acid sequence constituting a mature enzyme as represented by SEQ ID NO: 3 or an amino acid sequence resulting from deletion, substitution, situs inversus arrangement, addition or insertion of a part of amino acids thereof, or derived from Alkaliphillus transvaalensis. The protease cleaves 26 peptide bonds among 29 peptide bonds of acidic insulin B-chain.

An insert molding method and apparatus not requiring a multiple movable molds and permitting stable insert molding to be performed by means of light, small-sized equipment. A robot for removing a molded product and a robot for placing an insert member are arranged around a mold clamping mechanism, and making them perform removal of a molded product and placement of the insert member, respectively, during a mold opening process of a molding cycle. The molding apparatus does not requirs a plurality of lower molds (stationary molds) and accordingly permits to eliminate a turntable or a sliding table, whereby the molding apparatus can be reduced in size and weight. Further, since only one lower mold suffices to obtain one type of molded products, the manufacturing cost of molds can be reduced and the mold temperature control can be made easier, so that not only the molding conditions are stabilized but also the life of the mold can be prolonged by eliminating the poor positioning.

A nozzle hole sealing device for an injection nozzle capable of blocking a hole at the tip of a nozzle by using a robot in purging an injection molding machine. The nozzle hole sealing device includes a tool changer for connecting the nozzle hole sealing device to a wrist of the robot and a nozzle sealing body for sealing a nozzle hole by contacting the nozzle tip of the injection molding machine, thereby composing a nozzle sealing robot tool as a whole. A chuck mechanism for keeping a nozzle tip in contact with the nozzle sealing body, a heat reserving heater for a nozzle tip contact portion, and a resin passage ranging from the nozzle tip contact portion to a purged resin discharge surface including a constant pressure open value disposed in the middle of the passage may be further included.

A method of locating a fault point in a parallel two-circuit transmission line in an n-terminal system. When a single fault occurs at one place in one circuit of the transmission line and when a multiple fault occurs at the same place in the two circuits, a distance to the fault may be calculated by the method of this invention. The method comprises the steps of transforming the transmission line into a T three-terminal parallel two-circuit transmission line circuit having three branches, calculating a value representing a length of one of the three branches on the basis of differential currents flowing into the branch points of the transmission line, determining if that value represents the distance from a terminal connected to the branch point to the fault point, employing the value as the distance to the fault point if the value represents such a distance, repeating the value calculation and determination for the other two branches if the value does not represent the distance to the fault, determining a next branch point for which to perform equivalent transformation with respect to, and repeating the previous steps until the fault is found.
