A computer comprising a casing forming an outer appearance and having a main board attaching surface to which a main board is attached, further comprises a main board supporting unit provided on the main board attaching surface so as to support the main board, the main board supporting unit comprising a holder having a locking part, slidably combined to the main board attaching surface, and preventing the main board attached onto the main board attaching surface from moving; and a guiding part f...

A computer having a computer main body mounted with a plurality of hardware, the computer also having: a port part provided on a part of the main body and having at least one port; a cover slidably connected to the computer main body to open and close the port part; and a guide gear, provided between the cover and the port part, to guide the cover to slide between an open position, at which the cover opens the port part, and a closed position, at which the cover closes the port part. Thus, the c...

Provided is a computer with a case and a plurality of parts, including heat generating components that generate heat when operated, installed in the case, wherein the case includes a plurality of plates, and heat generated by at least one of the heat generating components when operated is transmitted to at least one of the plates via a heat conduction unit, which connects the at least one of the heat generating parts and the plate, and externally dissipated from the case. The heat generating com...

A computer having a main casing to accommodate a plurality of hardware components such as a CPU, comprises a heat dissipating assembly which is disposed on the CPU, and includes a heat transmitter formed with a through hole, and a plurality of heat dissipating fins standing on the heat transmitter so as to dissipate heat generated by the CPU; a supporter installed in the heat dissipating fins, being disposed perpendicularly to the heat dissipating fins; a push member including a lever pivoted on...

An exemplary computer includes a host machine, and a display device. The host machine defines a recessed portion in a side panel thereof to receive the display device therein. The display device includes a frame, and an LCD panel installed in the frame. The recessed portion includes a pair of elongated grooves defined in one pair of sidewalls thereof, and a plurality of vents defined in a base wall thereof. The frame includes a pair of posts extending from side portions thereof to engage in the ...

Apparatus and methods are disclosed for defining and controlling the relative positioning of symbols in a computer-based imaging system for generating images suitable for controlling a printing operation. Information describing the symbols is stored in a memory and is retrieved and the corresponding symbol relatively positioned on an imaging device in response to a control program and an input specification of the desired coincidence of "concatenation points" associated with each symbol.

A data processor has provision for error recovery by the division of a program into a set of program blocks. The apparatus has a main store and a cache store that preserves the states that have previously been taken up by items of information prior to commencing each block so that the states of the items of information prevailing at the beginning of a block can be restored if required.

A minicomputer is provided with special function keys for computing biorhythms and the biorhythmic compatability of two individuals. Display means for displaying, unambiguously, the biorhythm computed by the computer. Signal indicia indicate when one or more of the biorhythm cycles as computed by the computer, are at a critical or minicritical stage.

1. In an ordnance projectile having a side-spray warhead with a static frentation velocity V.sub.FS, an ordnance fuze comprising: radar means for making measurements of range and sight angle of a target; sources of fixed voltages proportional to predetermined target coordinates Z.sub.1, Z.sub.2, and Z.sub.3, in a coordinate system that rides with the fuze, the fuze trajectory being in the plus-Z direction; means for obtaining three voltages proportional to r.sub.1, r.sub.2, and r.sub.3, where r....

The disclosed device is an analog computer for analyzing data from measurements of physical phenomena or manufacturing processes involving random quantities. The computer includes noise generators whose amplitudes and spectra can be controlled to represent the random variables of the physical system or process under investigation. The random signals, and any periodic signals which may be involved, are fed into the circuit analog of the physical system. The output of the circuit analog is fed int...
