Title: Thin film thermistor
Inventor: ITO MASAHIKO
IPC: H01C7/04
Filed: 1988-03-31
Abstract: PURPOSE:To improve thermal resistance of a thin film thermistor by constructing an electrode film by sintering Au-Pt electrode paste and specifying a weight ratio of (Pt particle)/(Au particle + Pt particle) in metal particles in the electrode film. CONSTITUTION:A pair of Au-Pt electrode films 2 are sintered and formed on one surface of a planar alumina substrate 1. An SiC film 3 is formed on the one surface of the substrate 1 and on the electrode films 2 so as to interconnect the electrode films 2. Pt lead wires 4 are molded to the electrode film 2 and thereafter a glass coating layer 5 of 670 deg.C transition point is formed on the electrode films 2. In the formation of the electrode films 2, a weight ratio (Pt particle)/(Au particle + Pt particle) in metal particles in the electrode films 2 is defined to be 1/2 or more. Hereby, less aggregation of Au particles is sufficient to stabilize a contact interface between the SiC film 3 and the electrode films 2. Thus, thermal resistance of a thin film thermistor can be improved.

Abstract: PURPOSE: To prevent the propagation of harmful bacilli at filter, reservoir, etc. by placing bacilli suppressor at the water tank of humidifier.  
     CONSTITUTION: In the constituion, taper type pump 5 rotates which is equipped with cylinder-shaped filter driven by motor 3, water 1 stored within the reservoir is lifted up by centrifugal force, and is overflowed outside when the water surface level reaches over outlet port 7. At the same time, air being sucked thru filter 6 by fan 4 is discharged outside together with the vapor being discharged by pump 5. Because, water 1 being held within the reservoir 2 is disinfected by the chemical agent contained in the bacilli suppressor 8, various bacilli adhered to the filter 6 are deprived of their propagation capability. Thus, because the propagation of various bacilli in the reservoir 1 is inhibited, there exists no fear of generating putrid smell. Moreover, furnishing of heavy metal inside the reservoir 2, or placing bacilli inhibiting agent packed in net within the reservoir is also recommendable.

Abstract: PURPOSE:To make high reduction rolling possible without breakdonw, sagging and flawing of a strip in single stand multiple passes rolling by setting the peripheral speeds of work rolls and the speeds of the strip at specific relations. CONSTITUTION:Work rolls 11-14 and backup rolls 15, 16 are disposed in one row with the roll centers on a perpendicular line (l). A strip 1 is wound on the half circumference of the rolls in order of the 1st-3rd passes P1-P3. The peripheral speeds V1-V4 of the rolls 11-14 are larger the nearer the outlet side of the rolling mill like V1<V2<V3<V4. If the speeds of the plate 1 at the inlet side and plates 2-4 after passage of the respective passes are defined as V1-V4, these are V1<V2<V3<V4. Here 0.8<=v1/V1<=1 and if this ratio is below 0.8, flaws are produced, and if it is larger than 1, defective gnawing is apt to occur. The ratio with other roll pair is 0.8<=vn/Vn<1 (n=2, 3, 4). If this ratio is below 0.8, flaws are produced and if it is larger than 1, sagging occurs.

Abstract: PURPOSE:To improve photosensitivity for a short wavelength side and a long wavelength side by arranging amorphous Si at a light sensitive side on a conductive substrate wherein amorphous Si and amorphous Ge having junction structure respectively are laminated. CONSTITUTION:An amorphous Si layer having a semiconductor junction has sensitivity for a short wavelength of mainly 0.4-0.7mum in solar light and converts the short wavelength into electrical energy. Amorphous Ge having a semiconductor junction converts a wavelength light of 0.65-1.1mum in solar light passed the amorphous Si layer into electrical energy. Therefore, the short wavelength light is effectively absorbed into the amorphous Si layer and the long wavelength light is effectively absorbed by the amorphous Ge layer and both of them become photocurrent. Therefore, the characteristics of photosensitivity will remarkably be improved.
