The device for placing histological and biological samples encompasses a working area, a bin for cover glasses with a slot in the lower part, a cover glass pusher embodied in the form of a plate, the thickness of which is less than the thickness of the cover glass, a unit for placing the cover glass, which can be reciprocally displaced above the working area, and a press connected to the drive for reciprocally displacing the cover glass placing unit. This unit is embodied in the form of at least one spring-loaded, narrow plate or needle, the length of which exceeds the width of the pusher, and situated directly under the cover glass pusher in the same fastener. Said fastener is connected to the reciprocating motion drive in a direction perpendicular to the working area, wherein the reciprocating motion drive is a carriage. The carriage also accommodates guides for lowering and lifting the press. The press is embodied in the form of at least one elastic clamping element secured to the arm. The arm has a side stop placed in contact with the carriage guides.

A safety handle is provided for manually rotating a motor shaft for a stone grinding mill. One end of the handle is curved to encompass a portion of the shaft periphery. A hook at the end of the curved portion fits into the keyway of the shaft. The handle arm extends radially from the shaft with a hand grip at the end opposite the curved portion. When torque is applied to the handle in the direction of normal motor rotation, the curved portion and hook grip the shaft by rotational leverage and transmit the torque to the shaft. If the motor is inadvertently started with the handle on the shaft, inertia and gravity will cause the handle to disengage and roll off from the shaft to prevent damage and injury. The hand grip is attached to the handle so as to allow only manual rotation of the shaft in the normal motor direction. Alternately, the handle is bent transverse to its longitudinal axis to extend outward from the motor and thus enable rotation only when mounted properly on the shaft.

There are provided a printing apparatus and a method for processing real-time commands using the same. The printing apparatus is able to be stably operated without any mechanical troubles such as degraded performance of the printing apparatus, which are caused when real-time commands are analyzed and processed on a receive interrupt routine, by detecting real-time commands from data transmitted from the host computer, separately storing the detected real-time commands in a real-time command buffer and processing the stored real-time commands in preference to the other data.

A laminating apparatus having a thickness-detecting function is provided. Before the laminating operation is done, the thickness of the article to be laminated is detected by a thickness detecting mechanism of the laminating apparatus. According to the detected thickness, the temperature or the rotating speed of the heating roller of the laminating apparatus is dynamically adjusted.

An electron emitting element of the present invention includes an electron acceleration layer provided between an electrode substrate and a thin-film electrode, which electron acceleration layer includes (a) conductive fine particles and (b) insulating fine particles having an average particle diameter greater than that of the conductive fine particles. The electron emitting element satisfies the following relational expression: 0.3x+3.9≦y≦75, where x (nm) is an average particle diameter of the insulating fine particles, and y (nm) is a thickness of the thin-film electrode 3. Such a configuration allows modification of the thickness of the thin-film electrode with respect to the size of the insulating particles, thereby ensuring electrical conduction and allowing sufficient current to flow inside the element. As a result, stable emission of ballistic electrons from the thin-film electrode is possible.
