摘要： PURPOSE:To improve space saving and portability by constituting an information processor unitedly with an image scanner. CONSTITUTION:This information processor 1 consists of a display part 2 and a body part 3 and is constituted of an image scanner part for reading out image information from an object 6 to be inputted, a screen part 4 for displaying read contents and an input part 5 for editing the displayed result. Consequently an exclusive space to be required for a conventional image scanner to be externally connected can be eliminated and space saving corresponding to the space of the image scanner part can be attained. Since the portability of the processor is improved, information whose input from a conventional fixed means is difficult can easily be inputted.

摘要： PROBLEM TO BE SOLVED: To provide a device having extendability such as the extension of an option board and a device and constitution matched with the application format of a hard disk. SOLUTION: An electronic instrument consists of a BASE board, an audio board and an extended platter board 28 as its basic constitution, includes device parts such as an FDD and a CD-ROM and has constitution matched with the application format of a hard disk. Since devices and option boards can be exclusively loaded, the instrument can be used by constitution matched with the application format, and when hard disks for 3.5in. and 2.5in. are prepared, extendability can be improved. When a 2.5in. hard disk is packaged, the hard disk can be loaded without changing an I/F cable and the maintenability and assemblability of the electronic equipment can be improved.

摘要： PROBLEM TO BE SOLVED: To eliminate need for replacement of parts and to eliminate need for maintenance and management of parts for replacement by eliminating need for replacement. SOLUTION: A fuse housing 1, a polygonal cylinder 2, arranged within the fuse, and a rotary knob 3 required for rotating the polygonal cylinder 2 from the outside, are provided. On each surface of the polygonal cylinder 2, cylinder side contact terminals 11 on both ends and fuse elements 20 between these terminals 11 are provided. The cylinder side contact terminals 11 make an electrical connection with the outside with housing side contact terminals 12 connected to terminals 10 for soldering. Furthermore, the terminals 10 for soldering are soldered to electrical circuit terminals 100, to electrically function as protective devices for electronic circuits. A new fuse will be used by rotating the rotation knob 3, after fusing due to overcurrent, whereby recovery can be performed easily without requiring part replacement.

摘要： PURPOSE:To provide the information processor capable of improving energy efficiency by effectively utilizing excess heat generated by the information processor. CONSTITUTION:Insecticidal effect inside the information processor and at its peripheral space is generated by evaporating an evaporative liquid insecticide mounted at an insecticide cartridge fixing housing 4 installed on this side from the side face of a main body 1 of the information processor by using heat generated from a radiating member 5 fitted to heat generating parts 6 inside the main body 1. Thus, energy can be saved by utilizing the heat generated from the information processor as a heat source for an insecticidal device.

摘要： PURPOSE: To enable heat released from a semiconductor element to be efficiently dissipated into an ambient atmosphere by a method wherein one or more through-holes are provided to the heat dissipating surface of a fin so as to enhance air located between a mounting surface of a heat releasing body such as a semiconductor element and the fin in mobility. CONSTITUTION: Semiconductor devices 50 to 52 are located on a board 30 inside a case 70, and a heat dissipating fin 20 where through-holes 10 are bored is formed on the semiconductor device 50 through the intermediary of a conductive member. Then, convective warm air on the surface of board 30 around the semiconductor device 50 is enhanced in mobility to the outside. The fin 20 is slightly lessened in heat dissipating area by the through-holes 10 provided to its surface, but the inner air is enhanced in mobility, so that the fin 20 is capable of more efficiently dissipating heat into an ambient atmosphere than a conventional flat plate. The fin 20 hardly restrains heat released from both the semiconductor device 52 mounted under the fin 20 and the surface of the board 30 from being dissipated, so that, the fin 2O is capable of efficiently dissipating not only heat released from the semiconductor device 50 which is kept in contact with it but also heat released in all region below the film 20 into an surrounding air.
