Abstract: A radiation image read-out apparatus comprises a system for scanning a stimulable phosphor sheet carrying a radiation image stored thereon with stimulating rays in a main scanning direction, a system for moving the stimulable phosphor sheet with respect to the stimulating rays in a sub-scanning direction, and a photodetector for detecting light emitted by the stimulable phosphor sheet when it is exposed to stimulating rays. A stored energy signal output device receives information on the level of radiation energy stored on the stimulable phosphor sheet, and generates a signal corresponding to the information. The radiation dose at image recording is used to provide the information on the level of stored energy. A stimulation energy adjuster receives the signal generated by the stored energy signal output device, and adjusts the level of stimulation energy of stimulating rays per unit area of the stimulable phosphor sheet based on the signal.

Abstract: In an injection mold for molding an article having an undercut at at least one end portion, the movable mold half has a slide core which defines the inner surfaces of the end portion and the undercut, and a main body which defines the inner surface of the other portion of the article.

Abstract: A ball valve is provided with a blocking mechanism which automatically blocks its control shaft in its respective rotary position between a closure position and an open position when the control movement takes place too rapidly. The blocking mechanism responds to the respective rotary position of an annular inertia body which is rotatably mounted on the ball valve housing and the rotary movement of which effected by spring action is initiated by the rotation of the control shaft and is retarded by its inertia. On adequately slow actuation of the control shaft the blocking mechanism does not become operative. When the actuation is too rapid and could lead to potentially damaging high pressure peaks the control shaft is blocked by the blocking mechanism.

Abstract: A signal processing method in autoradiography for determination of the base sequence of DNA or a DNA fragment, employing groups of radioactively labeled base specific cleavage products or mixtures thereof obtained by specifically cleaving the DNA or DNA fragment labeled with a radioactive element and resolved one-dimensionally in parallel relation to each other to form resolved rows on a support medium. An autograph is obtained having locational information on groups of radioactively labeled cleavage products contained in the rows on the support medium. An electrical digital signal corresponding to the autoradiograph is then generated by recording and reproducing from a stimulable phosphor sheet the radiation energy stored therein. Sampling points in each resolved row of the digital signal are next detected. Reference sampling points are then determined in a plurality of reference rows which are either directly provided on the support medium and/or synthesized from certain resolved rows.
