Title: Printed board
Inventor: ITO TAKESHI
IPC: H05K1/02
Filed: 1987-09-02
Abstract: PURPOSE:To prevent the side etching of a conductor as well as to contrive improvement in accuracy of a pattern by a method wherein an etchant escape hole penetrating a substrate is provided between the conductive patterns on the surface of the substrate, and the etchant is prevented from collecting between the conductive patterns when an etching treatment is conducted. CONSTITUTION:A conductor 2 is formed on the whole surface of both sides of a substrate 1. Then, an etchant escape hole 3 is formed at the preset position between the patterns of the conductor 2. An etching resist 4 is formed into the pattern corresponding to the patternization of the conductor 2. The conductor 2 on the part which is not protected by the etching resist 4 is removed by conducting an etching treatment, and the conductor 2 is patternized. In this etching treatment, as the etchant flows out downward passing through the etchant escape hole 3 which penetrates the substrate 1 located between the patterns of the conductor 2, the etchant is hardly collected between the patterns of the conductor 2. Accordingly, the generation of the side etching on the conductor 2 can be prevented.

Title: Cooling device for electronic equipment
Inventor: KOBAYASHI MICHINOBU
IPC: G05D23/19
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent the temperature rise of an electronic equipment despite an off state of a main power supply by providing an auxiliary power supply to supply a firm power in addition to the main power supply and supplying the power from the auxiliary power supply to a cooling means for cooling the inside of the electronic equipment. SOLUTION: The supply of power of a main power supply part 2a is discontinued and therefore an electronic equipment 1 is turned off. Thus a control part 5 stops the supply of power to a fan 3 from an auxiliary power supply part 2b. However, the part 5 continues the supply of power to a memory circuit 1b via the part 2b. When a temperature sensor 4 detects that the ambient temperature of the part 2b exceeds a prescribed level, the part 5 supplies the power to the fan 3 via the part 2b to prevent the temperature rise of the part 2b. Then the internal heating value of a power unit 2 is reduced compared with a case where the equipment 1 is kept in an on state. Thus the power supplied to the fan 3 is also reduced, so that the power consumption and the noises of fan 3 can be reduced. Then the part 5 stops the supply of power to the fan 3 when the temperature detected by the sensor 4 falls.
