Title: Cooling structure for electronic device
Inventor: TANAKA SHINJI
IPC: G06F1/20
Filed: 1993-12-22
Abstract: PURPOSE:To make a work station and a computer thinner by moving heat generated by an electronic device to a case body and radiating the heat from the surface of the case body with a wide surface area. CONSTITUTION:The heat generated from the electronic device 3 is moved through a heat conductive projection part 2 integrally formed with the case body and closely stuck to the electronic device 3 to an upper part case body 1 and thereafter, radiated from the outer surface of the case body to the air. In this case, the heat conductive projection part 2 is integrally formed with the upper part case body 1 and the shape of the heat conductive projection part 2 is in a structure for which the width is changed in a tapered shape to the side of radiating the heat, that is, toward the side of the upper part case body 1. By performing constitution in such a manner, the heat from the electronic device 3 is distributed and the local temperature rise of the outer surface of the case body is prevented. Also, by applying heat conductive grease to the boundary of the electronic device and the projection part, the heat is further more efficiently conducted.

Filed: 1989-12-13
Abstract: PURPOSE:To accurately monitor the drop of the battery voltage by negating the output signal of a battery voltage detector for a prescribed period covering the start of oscillation of a CPU clock through the stabilization of the oscillation. CONSTITUTION:A CGC 6 controls an oscillation circuit with a PONSET signal and a STOP signal, and the PON and the BLDM (battery voltage detector) are set at 1 with the PONSET signal set at 1. Thus the CGC 6 starts the oscilla tion. The output OSC of the oscillation circuit serves as a counting signal of a counter 17 and therefore the counter 17 starts its counting operation. When the oscillation is stabilized and the counter 17 is counted up, a CPU is set at 1. Thus the BLDM is reset and a CPUON is set at 1. Then a CPUCK is outputted and the counter 17 is reset. The oscillation is stopped when the STOP signal is set at 1 and then both PON and CPUON are reset.

Title: Magnetic recording medium and its production
Inventor: AOYAMA SHIGEO
IPC: C09D175/00
Filed: 1989-12-14
Abstract: PURPOSE:To improve mechanical characteristics and electric characteristics of a magnetic recording medium by allowing a small amt. of spherical solid additive to be omnipresent in the vicinity of the surface of the magnetic layer. CONSTITUTION:The spherical solid additive of <=1mum mean particle size is allowed to be omnipresent in the vicinity of the surface of the magnetic layer. Namely, in the spherical solid additive having <=1mum average particle size, the wearing amount of a magnetic head is smaller than that of an aspherical and squarish solid additive, and the wearing amount of a head can be properly suppressed even when a considerable amt. of the additive is distributed on the surface of magnetic layer. Since the shape of the additive is spherical real contact area between the solid additive and the magnetic head can be reduced to insure the good traveling property. Thereby, the recording medium excellent in mechanical characteristics and electric characteristic is obtained.
