Title: Electronic device
Inventor: MATSUO KAZUHIRO
IPC: F25D1/00
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain or replace a cooling unit with the main unit of an electronic device kept operating by placing the cooling unit in a housing box in such a manner that it can be freely removed, the housing box which can be attached to and detached from a rack, and providing the box with a panel for closing its opening. SOLUTION: The rack 10 of an electronic device is an input/output processor of a computer, for example. A cooling fan unit 50, 60 is mounted on the rack for introducing cooling air. The cooling-fan unit 50, 60 introduces cooling air from beneath the floor in the direction of the arrow marked with 'X1', and sends the air upward in the direction of the arrow marked with 'X2' to cool a power supply unit 20. It also cools electronic units 30, 40 installed in upper positions. For example, the cooling unit 50 is secured with screws 54d with the fan unit 54 placed in a housing box 52. When the housing box 52 is drawn out of the rack 10 for maintaining or replacing the fan unit 54, the box 52 is provided with a back panel 52d for blocking up the opening formed in the rack 10. This makes it possible to maintain or replace the fan unit 54 without stopping the entire system.

Filed: 1988-12-10
Abstract: PURPOSE:To obtain a speaker with stable quality by forming the mixed composition layer of vibration loss material resin and fluororesin on the surface of a vibration substrate cloth directly, or via a vibration loss material resin layer.

Filed: 1994-12-16
Abstract: PURPOSE: To prevent the drop of horizontal synchronizing initiation timing signals required in the scanning initiation at the time of allowing a plurality of laser lights accompanied by printing data to horizontally scan on the phtosensitive drum surface. CONSTITUTION: During the period of permitting a plurality of laser beams Ls1 -Lsn based upon printing data to scan horizontally while taking each horizontal synchronism, since such horizontal synchronism initiation timing required for the horizontal scanning initiation is taken by giving time delays every scanning row, timing laser beams L1 -Ln are allowed to scan on the surface of a laser beam detection sensor 205 while giving time delays for only the number of scanning rows from a laser generation mechanism. The width in the laser scanning direction of the sensor 205 is made larger than the total amount of distances among laser beams L1 -Ln . Every time when laser beams L1 -Ln are incident on the sensor 205 successively and the sensor outputs increase step by step, the circuit 103 acts to generate timing signals one after another.

The resistance value of the heating element is made high by at least three times or more at a time of prescribed high temp. in comparison with a time of ordinary temp. In the case of conducting electricity to the heating element from a power source, when the temp. of the inside of the vessel is detected by a temp. detector and made lower than the prescribed value, the supplied current is controlled at the preset current value. When the temp. of the vessel is made higher than the prescribed value, the current value is controlled so that it is regulated to the set temp. Thereby the temp. of the inside of the vessel is raised to the set temp. in a short heating time.

Inventor: TOJO JUNICHIRO
IPC: H01L29/78
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To enable lessening of deterioration in step coverage, decrease in dielectric withstand voltage, disconnection of wire of a metal wiring layer by a method wherein a conductive layer is thermally oxidized, and an interlayer insulating film, with which the conductive layer filled in a groove and the conductive layer left in a pad region are electrically separated, is formed. SOLUTION: A photoresist PR is selectively formed on the region where a lead-out electrode pad is formed, and a polysilicon layer 16 is etched back to the degree that its thickness becomes one half or less. Then, after the photoresist PR has been exfoliated, the polysilicon layer 16 is thermally oxidized at about 1100 deg.C for 20 minutes under a steam oxidization state. Thus, polysilicon is left in a trench 14 and on a pad region, and the polysilicon is electrically separated by the interlayer insulating film 17 consisting of an oxide film formed by the oxidization of the polysilicon layer 16. Accordingly, the deterioration of the stepcoverage on stepping, the lowering of dielectric withstand voltage and the disconnection of a metal wiring layer can be decreased.
