Disclosed are a piston for a micro-volume syringe and a plunger. The micro-volume syringe has a syringe barrel with a space defined in it. The piston is slidable on and along a wall of the space. A leading member to be arranged on a side where the piston comes into contact with a solution filled in the space and a trailing member to be arranged on a side where a plunger rod is to be connected, the latter side being opposite to a solution side of the leading member, have been integrated with each other. The trailing member has a higher hardness than the leading member. With the micro-volume syringe in which a drug solution can be filled in a very small quantity, the piston makes it possible to perform smooth drawing and ejection of the drug solution without leakage. Even if the small piston connected to a tip of the plunger rod is operated in a direction that the piston is to be pulled out of the syringe, the plunger rod does not slip off from the piston accidentally. The piston and plunger are optimal for the micro-volume syringe.

A plunger rod useful for sliding a piston inserted in a syringe barrel has a threaded portion formed at an end of the plunger rod to attach the piston on the plunger rod and a flange formed at an opposite end of the plunger rod. The threaded portion and the flange are integrally connected together by a cylindrical member having an outer diameter such that the cylindrical member can be inserted with contact slidability in the syringe barrel, for example, an outer diameter equal to or slightly smaller than an inner diameter of the syringe barrel.

A plastic-made cap for a vial having a lip, said cap being useful as a separation-preventing cap for a plug that seals up an opening of the vial, includes a top wall portion having an outer circumference and centrally defining an opening, and a cylindrical skirt portion extending downwardly from the outer circumference of the top wall portion and being open at its lower end. The skirt portion has an inner diameter (a) greater than an outer diameter (b) of the lip of the vial. The skirt portion is provided on its inner wall with plural ribs formed in a direction perpendicular to the top wall portion. The plural ribs are arranged in pairs at equal angular intervals between the respective pairs of ribs. Further, engagement claws are arranged between the respective pairs of ribs such that the engagement claws can be brought into engagement with an underside of the lip of the vial.

A control system comprises a plurality of peripheral devices represented as objects, and a controller connectable to the plurality of peripheral devices via a common communication line for unitarily controlling the plurality of peripheral devices. The controller is arranged to be connected to an arbitrary number of peripheral devices selected from among the plurality of peripheral devices, read control information stored in the arbitrary number of peripheral devices via the communication line into a predetermined memory area of the controller in a predetermined format so that the controller can control the arbitrary number of peripheral devices. The controller is also arranged to issue a command and transmit the command to each of the arbitrary number of peripheral devices via the communication line.

An inter-frame motion detector detects the presence or absence of motion between frames on the basis of judgment whether or not an inter-frame difference is not more than a set value. A vertical edge continuity detector calculates difference values between an object pixel and pixels above or below the object pixel in an inlaid picture, and detects whether or not there is horizontal continuity of an inter-field vertical edge on the basis of judgment whether or not the signs of the difference values are the same continuously over not less than a predetermined number of pixels, in the horizontal direction, including the object pixel. When it is detected that there is no motion between frames, and it is detected that there is horizontal continuity of the inter-field vertical edge, it is judged that a picture is in a completely still state.
