Abstract: The game machine and game program of the present invention display, at the start of a game, multiple static symbols by constantly changing to various types of symbols including the wild symbol. The game machine then executes a static display by displaying such changing symbols statically again in each display area and recognizes the arrangements of each static symbol. Then, the game machine visually displays the arrangement of the symbols by which multiple wins are established or the win line related to such arrangements of the symbols, when the pre-determined combinations of symbols, in which at least one wild symbol is included, are arranged so that multiple wins are established. The game machine and game program according to the present invention increases the player's interest and arouses the player's anticipation.

The computer includes a per-operation transmission setting device for setting to the automatic synthesis apparatus as to whether transmissions of the operation notification mails along the synthesis procedures to the computer are performed or not, and an operation notification mail display device for displaying the operation notification mail. The operating conditions can be monitored by the operation notification mail display device as desired.

Abstract: An automated chemical synthesizer includes a reaction vessel and a collection vessel. A passage block in which the passage is formed and which is provided between the reaction vessel and the collection vessel when the collection vessel is connected to the reaction vessel in a collection position. The passage includes a discharging hole and a connecting hole which is provided to correspond to the collection vessel. The collection vessel contacts the passage block around the connecting hole. The passage block includes upper and lower plates. A lower portion of the connecting hole formed in the lower plate has a size such that a top portion of the collection vessel fits into the lower portion. An upper portion of the connecting hole formed in the upper plate has a size such that a top portion of the collection vessel contacts the upper plate around the upper portion.

Abstract: A chuck table includes a pedestal having a circular depression formed in an upper surface thereof, and a disk-like chuck plate positioned in the depression of the pedestal.
