摘要:
A coin feeding apparatus for a coin handling machine of the rotatable disk kind includes a guide extending along the coin flow path in the vicinity of an opening of a guide ring. The guide is swingable between a first position where its face is smoothly aligned with the inner circumference of the guide ring and a second position where the face is not smoothly aligned. The guide means, when disposed in its second position, acts to prevent the jamming of coins when the coins are driven in a reverse direction back through the opening onto the rotatable disk.

The invention provides an apparatus for sorting various kinds of coins into various categories of coins. To this end, the invention includes a semicircular member having a plane surface and an arc surface. The semicircular member is capable of rotating between a first position wherein the plane surface is disposed substantially in the plane defined by a guiding edge and the arc surface is disposed within a guide rail and a second position wherein the plane surface is disposed normal to the guiding edge and the arc surface faces towards the upstream of the coin feeding direction. The semicircular member rotates from the first position to the second position when a first group coin is fed to collide with the semicircular member so as to diverge the coin away from the guiding edge so that the circumferential end of the coin closest to the guiding edge is disposed on a sort-out opening. The semicircular member returns to the first position when the coin passes the semicircular member.

摘要:
A high molecular compound useful as a non-radioactive carrier, which comprises at least one unit of (1) an asialoglycoprotein acceptor-directing compound and at least one unit of (2) a chelate-forming compound chemically bonded thereto, and which may be labeled with a radioactive metallic element to give a radioactive metallic element-labeled product useful as a radioactive diagnostic or therapeutic agent for liver.
摘要:
A radioactive diagnostic or therapeutic agent, which comprises a metallic element-labeled high molecular compound which comprises one unit of (1) a polyamine compound having at least three amino groups in the side chains per molecule, at least two units of (2) a chelate-forming compound having a carboxyl group, at least one unit of (3) a physiologically active substance and (4) at least two radioactive metallic elements, each unit of the chelate-forming compound (2) and the physiologically active substance (3) being combined to any of the amino groups in the side chains of the polyamine compound (1) and each of the radioactive metallic element (4) being chelate-bonded to the chelate-forming compound (2).
摘要:
A film image projecting apparatus such as a microfilm reader and a microfilm printer adapted to automatically retrieve desired information by searching blip marks provided laterally of frames in a roll film. Conventionally, a roll film containing a plurality of rows of frames has been retrieved in most cases by manually placing a target frame in an exposure section. The known apparatus also has the disadvantage of blip marks becoming displaced from an illuminated area when an image is projected in magnification onto a screen, thereby impairing the retrieval operation. The present invention provides a film image projecting apparatus having means for eliminating this disadvantage. More particularly, the disclosed apparatus comprises a film transport mechanism, a cross slide mechanism, a projecting optical system, and a control device for suitably controlling these elements to enable desired information retrieval. The film image projecting apparatus according to the present invention is particularly suited for retrieving and copying images photographed into a plurality of rows of frames in a roll film.
摘要:
A sorted coin counting apparatus for counting the number of various kinds of such mixed coins are made to fall into the various selecting holes, which are formed in the bottom of a coin selecting track, separately in accordance with the kinds thereof, while being unidirectionally conveyed on the selecting track, so that they may be sorted. The sorted coin counting apparatus includes a stacking cylinder for stacking therein each kind of the coins which have fallen into the corresponding selecting hole. Further inclusive is a counting conveyor belt mechanism which is operative to discharge the coins from the stacking cylinder to a counting passage and to convey the coins discharged to a collecting cylinder and further to a storage box through the counting passage. A counting gear is shaped and positioned to be stepwise turned by the coins which are being conveyed on the counting passage. A counter is made responsive to the stepwise rotations of the counting gear so that the number of the coins counted may be indicated.
