Title: Ventilator with filter
Inventor: AKATSUKA JUN
IPC: F24F7/007
Filed: 1990-11-30
Abstract: PURPOSE:To set an adequate differential pressure corresponding to the installation situation of a ventilator and properly indicate the clogging degree by a method wherein a differential pressure indicator is equipped with a differential pressure setting device to optionally set a differential pressure value. CONSTITUTION:A differential pressure sensor main body 7 has two pressure detecting ports 9a and 9b. The pressure detecting port 9a detects the pressure of the inside 10 of a ventilator, and the pressure detecting port 9b is connected to a pipe 11, that is extended from the inside of the ventilator into a room, to detect the pressure of the inside 12 of the room. The differential pressure between the pressure detecting ports 9a and 9b is converted into an electric signal. When the ventilator is operated for a long time, dust attaches on a filter 8 and the differential pressure across the filter 8 increases, resulting in an increase in the differential pressure between the inside of the ventilator and the inside of the room. A differential pressure indicator 15 is equipped with differential pressure setting members such as a volume control knob, a changeover switch, or others, and the differential pressure value is set during or after the installation work of the ventilator.

Filed: 1990-11-30
Abstract: PURPOSE:To manufacture a cap layer without high temperature growth and to improve heat dissipating characteristic when a junction down method is used by etching the surface of a block layer with isotropic etchant before the cap layer is formed. CONSTITUTION:Before a cap layer 9 is formed, the surface of a block layer 8 is etched with isotropic etchant having small surface azimuth dependency with an SiO3 film 14 as a mask. After the film 14 at the top of a ridge 7 is removed, the layer 9 made of p-type GaAs is formed on an exposed protective layer 13 and the layer 8 by a low-pressure MOCVD method. In this case, the surface of the layer 9 becomes smooth by reflecting the shape of the surface of the layer 8 becoming smooth, and the step of a recess 12 above the ridge 7 is further reduced. When a junction down method is used, an electrode 10 formed on the surface of the cap layer can be brought into contact with melted metal in high yield, heat dissipating characteristic of an element is improved, and reliability of the element is improved.
