摘要:
A reader printer for copying image information from a microfilm having a multiplicity of image frames recorded therein, frame marks for retrieval affixed thereon opposite the image frames, and batch marks for retrieval affixed thereon opposite the leading image frames of batches of image frames. When one of the batches of image frames is designated, the information contained in all the image frames in the batch is recorded sequentially from the last through the first of the image frames. The positioning of each of the image frames included within the designated batch at a prescribed location of the projected light path is accomplished by detecting the frame marks with a sensor, memorizing the positional relationship of the frame marks prior to the operation of print copying, and selectively imparting a motion to the microfilm based on the memorized data of position. The sensor is disposed at a position deflecting from the projected light path. Since the sensor is not affected by the light traveling through the projected light path, the positioning of the image frame at the center of the projected light path is accomplished with high accuracy. When a plurality of copies are to be produced from one image frame, the aformentioned data of positions between the frame marks are renewed each time the production of one copy is completed.

A microfiche reading apparatus for retrieving frame images recorded on a microfiche. This apparatus is automatically initialized in accordance with format information recorded in a bar code in a marginal section of the microfiche outside an image recording area. The apparatus comprises a movable support for the microfiche, a sensor for reading the bar code, and a control system for controlling movement of the support in response to the format information.
摘要:
A radioactive diagnostic agent which comprises a physiologically active substance and a radioactive metallic element combined with a compound of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are each hydrogen, C.sub.1 -C.sub.3 alkyl or phenyl. The agent is characteristic in having a high stability even after being administered into a human body and showing the substantially the same behavior as the physiologically active substance itself in a human body.

Herein disclosed is a coin selecting apparatus for selecting or classifying mixed coins in accordance with their diameters. The coin selecting apparatus includes a selecting track which is formed in its bottom with a plurality of selecting holes. These holes are arranged in a row in the flow direction of the coins and are sized to have stepwisely larger widths in the downstream direction of the coin flow so that they may allow the coins to pass down therethrough to be classified. The coin selecting apparatus further includes a selecting belt mechanism which is operative to convey the coins on the selecting track so that coins may fall into the selecting holes in order of increasing coin diameter. The selecting belt mechanism is composed of a plurality of belt carrying mechanisms which are arranged on the selecting track for carrying a corresponding number of belts such that the running directions of the belts are inclined at a preset angle with respect to the longitudinal direction of the selecting track and that each of the belts partially overlaps the next downstream belt.

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.

A porphyrin compound of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each --CH.dbd.CH.sub.2, --CH.sub.2 CHJ.sub.3, --CH(O-lower alkanoyl)CH.sub.3, --CH(OR)CH.sub.3 or --CH(O-lower alkylene-OR)CH.sub.3 ; R.sub.3 is --H, --COOH, --COO-lower alkyl, --COO-lower alkylene-OR or --COO-lower alkylene-OOC-Z; R.sub.4 is --H, -lower alkyl or -lower alkylene-OR; R is --H, -lower alkyl or a residue of a polyfunctional carboxyl compound excluding a hydrogen atom therefrom; Z is a residue of the compound of the formula (I) excluding R.sub.3 therefrom; A is --CH.sub.2 -- or --CO--; and the dotted line from the gamma-position indicates no bonding or a single direct bond; and the dotted line between the 7- and 8-positions indicates the presence of a single bond or a double bond; and its complexes with a metal(s) in the porphine skeleton and/or at the residue of the polyfunctional carboxyl compound, at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 being a group containing R which represents the residue of the polyfunctional carboxyl compound and R.sub.1 being capable of representing 1-iodoethyl in addition to said meanings when R.sub.3 is --COO-lower alkylene-OOC-Z, which shows a high accumulation in the locus of cancer with quick excretion from normal tissues.
摘要:
A kit for the administration of a radiopharmaceutical liquid composition has been developed, which includes a radiation-shielding injector accompanied with a syringe-type vial having a gasket therein, a seal cap and a plunger to be engaged with the gasket. The injector is made of a radiation-shielding tubular metal body covered with a plastic material having an exit at the bottom, the body being further provided with a lead glass window on its curved surface, a packing engaging the inside surface at one end of the body and a pair of wings having skid-proof ridges formed on at least one surface thereof, the wings being located at one end of the body. The body is so designed as to be shorter than the tubular portion of the syringe-type vial to be inserted therein, whereby the rear portion of the vial protrudes a little from the tubular body when the same is inserted into the body.
摘要:
A microfilm reader comprises a microfiche moving mechanism for sandwiching a microfiche film between an upper glass plate and a lower glass plate and moving the film in two-dimensional directions, and a projecting optical system for projecting images recorded on the film to a screen. The projecting optical system includes a projecting lens housed in a lens case placed on the upper glass plate of the microfiche moving mechanism. This lens case is raised away from the upper glass plate when the microfiche moving mechanism is in motion. The upper glass plate is raised only when the microfiche moving mechanism is in a home position for inserting and removing the microfiche film to/from a position between the upper and lower glass plates.
