摘要： PURPOSE:To improve the rigidity of the rear peripheral part of a disk cartridge by forming a joining part in the vicinity of the rear periphery of the disk cartridge. CONSTITUTION:To the rear peripheral parts of an upper case 6 and a lower case 7, members for joining, namely, a boss 13 for joining and a projection 17 for joining are projectingly provided, and a write protector 5 is set adjacent to the front periphery. Thus, since a distance from the joining part to the rear periphery of a disk cartridge 1 which is a free edge is made small, the rigidity of the rear peripheral part of the disk cartridge 1 is improved. For such a reason, even when, for example, an excessive force is given at the time of operating the write protector 5 or when the rear peripheral part of the disk cartridge 1 is collided with solid foreign materials by mistaken in the middle of handling, the rear peripheral part cannot be opened.

摘要： PURPOSE:To prevent erroneous insertion by providing a recessed stopper on the front edge part of a disk case on an opposite side in right and left with respect to the insertion direction of a position on which a lever is abutted. CONSTITUTION:When the disk case 1 is accurately inserted into an information reader 100, the case front edge part 6 is abutted on the lever 1001. The recessed stopper 7 is provided on the front edge part 1a of the case 1 on the opposite side in right and left of the lever abutting position 6. Even when the disk case 1 is erroneously inserted, namely, reversely inserted into the information reader 100 with such a constitution, the lever 101 is fixed to the recessed stopper 7 provided on the front edge part 1a of the case 1 and it operates as a trouble to the case 2, whereby more insertion can be prevented. Consequently, the damage of the disk or the like can previously be prevented.

摘要： An optical disc cartridge provided with a mechanism for preventing incorrect insertion of a cartridge. A cut-off portion is provided at a head and side portion at an inserting side of, for example, a 3.5'' erasable optical disc cartridge. The cut-off portion is located at an side opposite to a corresponding cut-off portion used in a 3.5'' (86 mm) floppy disc cartridge. A stopper is provided in a cartridge insertion portion of the reproducing apparatus to prevent incorrect insertion of the cartridge and is located to correspond to the location of the cartridge cut-off portion. A depression or the like is provided at a front end of the cartridge and at a portion symmetrical about an axis to an edge of the shutter where the shutter opening lever normally strikes.

摘要： A disc cartridge 100 has a shutter 101 opened automatically by a swinging arm 202 as the cartridge advances into a reproducing apparatus 200, the arm 202 lying beneath a stop 206 when the cartridge is fully inserted but, if the arm 202 jumps on top of the shutter and fails to open it, the arm abuts the stop 206 and by preventing full insertion prevents displacement of arm 203 and energisation of the disc motor. A bevelled corner 105 of the cartridge meets abutment 201 on full insertion so that if the cartridge is inserted wrong face up the non-bevelled corner will meet 201 and prevent full insertion. Alternatively, the cassette can have a notch on its leading edge in a position such that when insertion is wrong face up the shutter opening arm is engaged and trapped by the notch to prevent complete insertion.

摘要： The impeller (60) is intended for moving the cooling air through the heat exchanger of an air-conditioning unit. It comprises a hub (10) with a number of blades (71) each having a segment (75) near its tip edge (72), a leading edge (73), and a trailing edge (74). The tip segment region (75) has an S-shaped cross-section along a circular arc (between 0.7 and 0.9D) about the impeller centre (O). This cross-section has a point of inflexion or a flat portion between leading (73) and trailing (74) edges. The blade surface from this point or portion to the leading edge is concave and to the trailing edge convex.

摘要： PROBLEM TO BE SOLVED: To improve white balance, regarding a video display apparatus.
SOLUTION: At least two color separating means are arranged on an optical path between a lamp 9 and a light valve means 13, and light of a wavelength band from 480nm to 540nm is eliminated from the optical path by spectral characteristics of the separating means. Further, respective lenses and respective mirrors on the way from the illuminating system to a light valve element are constituted so as to transmit ≥ about 95% of light of the wavelength band from nearly 400 to 430nm, and light of the wavelength band from nearly 680 to 700nm.
