Machining apparatus for machining a workpiece with a machining tool, including a work holder for holding the workpiece, and a cold gas stream supply device including a cooling gas nozzle through which a cold gas stream is supplied to a machining point, and wherein the cooling gas nozzle is provided on the work holder, and the cold gas stream has a temperature lower than an ambient temperature of the apparatus. The apparatus may be a centerless grinding apparatus including a regulating wheel for rotating the workpiece, and a work rest blade cooperating with the regulating wheel to rotatably support the workpiece so that the workpiece is ground by a grinding wheel while the workpiece is held by the work holder between the regulating and grinding wheels. The cooling gas nozzle is desirably positioned such that a distance between the exit end of the cooling gas nozzle and the grinding point is not larger than a diameter of the workpiece. Also disclosed are machining process and cooling method and device using the cold gas stream.

An original feeding method for resting a plurality of originals on a platen side-by-side by using a recycle original feeding apparatus having a tray (thereby replacing a page sequence of the plural originals) includes the step of replacing a page sequence of the plural originals by resting the originals from the tray on the platen side-by-side in a feeding direction. The plural originals are then returned onto the tray from the platen in a stacking page sequence, and the plural originals returned to the tray and replaced in the stacking page sequence are rested on the platen side-by-side in the feeding direction.

A cyclone separator including a cylindrical vessel having a tangentially extending inlet at one axial end and a tangentially extending outlet at the other axial end so that fluid is introduced into the vessel from the inlet and produces a swirl flowing to the outlet. A capturing groove is formed around the vessel and opened to the vessel through a gap. A fluid passage is provided to extend from the groove to the axial center of the vessel so that a circulating flow is produced from the groove through the fluid passage to the axial center of the vessel. The portion of the fluid having a high concentration of a substance of a different density is therefore drawn from the area adjacent to the inner wall surface of the vessel to the groove and the substance is captured by the groove.

A tape recorder with adapter comprises a small size tape recorder including a playback function, a motor servo circuit and a low voltage and high capacity power supply. The small size tape recorder can be physically coupled with an adapter forming a variable speech control circuit or microcomputer circuit formed by IC or LSI components requiring a high voltage power supply. The adapter internally houses a high voltage and low capacity power supply.

A synthetic resin storage case which comprises a case body, a covering formed integrally with said case body, and a rear side plate which is provided between said case body and said covering and through which said covering is rocked, whereby when said covering is closed, a front side plate of said case body is overlapped on a front side plate of said covering to maintain said covering in a closed condition by an engaging mechanism provided between both said front side plates. It further comprises a shifting mechanism for slightly shifting said covering toward said rear side plate in accordance with the rocking movement of said covering at the time of closing said covering, so as to secure the function of said engaging mechanism.

A tape cassette includes a pair of tape hubs to which the opposite ends of a magnetic tape are secured. The tape running is conventional in that the magnetic tape wound on one of the tape hubs is taken upon on the other tape hub. The pair of apertures for receiving the tape hubs are formed as elongated elliptical slots. When the tape cassette is loaded in a tape recorder and a tape winding operation has proceeded until its one end is reached, the tension applied to the tape by the winding effort of the take-up hub shaft causes a displacement of the tape hub within its associated aperture, thereby permitting the end of tape to be detected for automatically stopping the tape recorder by either electrically or mechanically rendering the operating mechanism of the recorder inoperative. Alternatively, the end of tape detection may be utilized to activate an end of tape alarm.
