摘要: A penta mirror diagonal and zoom lens assembly for refracting or catadioptric astronomical telescopes includes a specially adapted zoom lens with a key extending outward from an objective lens and an adaptor designed for insertion and retention in a viewing end of an astronomical or catadioptric telescope. The adaptor includes a keyway which mates with the key on the zoom lens, thus allowing the zoom lens to be used only with the adaptor. The zoom lens itself is specially designed for use with astronomical or catadioptric telescopes.

摘要: In order to prevent the staining of magnetic heads of a magnetic recorder in a low humidity environment, a refrigeration device which refrigerates a magnetic tape is positioned so as to engage the magnetic tape prior to the tape engaging the magnetic heads. The refrigeration device comprises either a refrigeration post or a refrigerated semi-closed space and functions to transfer water to the magnetic tape.

摘要: A tuning fork-shaped quartz oscillator comprises a U-shaped quartz oscillator body which comprises of a pair of vibration arms having a rectangular cross section and a base connecting the vibration arms at one end. Four excitation electrodes are provided respectively on the four sides of each vibration arm, each electrode having a portion laid on two adjacent sides. The oscillator further comprises connecting means including a first input terminal and a second input terminal which supply drive voltage to the excitation electrodes so that the vibration arms keep vibrating in opposite phase relation in both a bending mode and a twisting mode.

摘要: A head cleaning device for use in a magnetic recording and reproducing apparatus comprises a cleaning roller in which a lubricant with an excellent lubricating action under low humidity conditions impregnates the soft material. This lubricant compensates for the drop in the natural lubricating action resulting from a moisture deficiency, and therefore prevents the production of seized deposits. Furthermore, the head cleaning device comprises a first cleaning portion impregnated with polymer resin and abrasive particles, and a second cleaning portion comprising only a soft material, the second cleaning portion can remove by wiping any abrasive particles or deposits left on the magnetic head surface immediately after the abrasive cleaning action of the first cleaning member.
