An ID barcode printing sectionprints IDs for identifying arrived mails. An address recognition sectionrecognizes address information for the primary sorting and the secondary sorting from the address images photographed by an image input sectionfor saving in an ID database. Based on the recognized primary sorting address information, the sorting control sectionsorts the mails in a sorting boxthat corresponds to a secondary sorting post office. Upon filling up the sorting boxes, the mails therein are transferred to a transportation medium. An ID writing sectionwrites secondary sorting address information of the mails in the transportation medium that is read from an ID databasefor recording on the transportation medium. Upon reading the address information that is recorded on the transportation medium by an ID information read-out section, a sorting control sectionin the secondary sorting post officeacquires the address information on each mail in the transportation medium for sorting each mail in sorting boxesfor delivery address.

Mail sorting system and method of sorting mails

The present invention provides a method for analyzing the C-terminal amino acid sequence of a peptide by applying reaction technique for successively releasing the C-terminal amino acids therefrom, which method can suppress, when releasing the C-terminal amino acids of the peptide in sequence, such as an undesirable side reaction as cleavage of peptide bond in the intermediate position of the peptide, and allows to carry out the chemical treatment thereof under widely applicable conditions. In the method according to the present invention, an alkanoic acid anhydride and a perfluoroalkanoic acid both of vapor phase, which are supplied from a mixture containing an alkanoic acid anhydride with a small amount of a perfluoroalkanoic acid added thereto, are allowed to act on a dry sample of the peptide to be examined in a dry atmosphere at a temperature chosen in a range of 15 to 60&#xb0; C.; whereby the release of the C-terminal amino acid is resulted from successive formation of a 5-oxazolone structure being followed by cleavage of the 5-oxazolone ring; and then the C-terminal amino acids sequence is identified by analysis based on the decrease in molecular weight in a series of the reaction products obtained.

An operating microscope apparatus wherein, in order that an operator or accessories with which the operator is equipped may not be likely to collide with a case containing a driving mechanism for moving a microscope assembly during the use, the operatability may be improved and the length from the case top surface to the focal plane of the microscope may be shortened, the case is formed so as to be movable integrally with the microscope assembly in the horizontal plane with respect to a supporting arm, a suspending member for suspending the microscope assembly integrally with the case is arranged so that its center axis may intersect at an angle with a normal passing through the rotation center of the case and the microscope assembly is fitted to the suspending member so that, when the case is in the center position of its moving range, the incident optical axis of the microscope assembly may coincide with the above mentioned normal.

Operating microscope apparatus

A movable microscope assembly includes a translational movement mechanism located between a microscope and tilting means associated with the microscope, for causing a translational movement of the microscope in a plane perpendicular to the observation optical axis of the microscope and in the directions of Y- and X-axes in such plane.

A zoom stereomicroscope with taking lens barrel comprises a binocular observation stereomicroscope, formed by a pair of observation optical subsystems, and an auxiliary optical subsystem which may be used for purpose of photographing or auxiliary observation. The auxiliary subsystem is focussed in the same manner as the observation subsystems. Each optical subsystem includes a zooming movable lens. The movable lenses are connected with associated drive members which are driven in unitary fashion to change the magnification in the respective subsystems simultaneously.

A pantograph mechanism comprises a support member adapted for mounting on a stationary support, a holding member disposed in parallel relationship with the support member and adapted for mounting on it a member to be moved, and a pair of links which connect the holding and the support members. The area occupied by the pantograph mechanism is minimized by means of a judicious choice of shape for the links, while permitting a translational movement of the holding member relative to the support member.

Pantograph mechanism

A plurality of foot-operated controllers are separately provided for controlling various operations such as the vertical movement of the body of a surgical microscope, the focussing of an objective or the like. Depending on the intended use, selected controllers are connected together by releasable spacers to provide a foot-operated controller assembly.

A magnification display device for displaying magnification on a part in the observation field of view or photographing field of view of a zoom type microscope. The device comprises a mirror frame for the microscope incorporating with a zoom lens, and a magnification display plate rotatably arranged in the mirror frame. A predetermined magnification on the magnification display plate is displayed in the field of view of observation optical system, photographing optical system or the like.

A controller comprises a first and a second pushbutton each carrying a pair of actuator pins of different lengths, first and second normally open switches located below each of the actuator pins having a reduced length, and a first and a second normally closed switch located below each of the other actuator pins. When depressed, each pushbutton causes its pin of an increased length to actuate its associated switch initially and then causes the other pin to actuate its associated switch. When the first pushbutton is depressed, a first circuit including the first normally open switch and the second normally closed switch in series is completed, and when the second pushbutton is depressed, a second circuit including the first normally closed switch and the second normally open switch in series is completed. When neither pushbutton is depressed, the first and second normally open switches prevent either the first or the second circuit from being completed. When the both pushbuttons are depressed simultaneously, the first and second normally closed switches are opened, thus preventing the completion of both the first and the second circuits.
