Title: Thermistor unit
Inventor: MITOMO AKIO
IPC: G01K7/22
Filed: 1987-06-22
Abstract: PURPOSE:To secure insulating property, by sequentially forming a lower substrate including fluoride resin and an upper substrate of tetrafluoroethylene perfluoroalkoxyethylene copolymer resin on the outer surface of a thermistor element. CONSTITUTION:Primer including liquid fluoride resin is applied on the outer surface of a thermistor element 5 to a thickness of 5-20mum by a spraying method. Then, the primer is left in a natural state or dried at a temperature of 50-80 deg.. Thus a lower substrate 10 is provided. Then, tetrafluoroethylene perfluoroalkoxyethylene copolymer resin with a size of 20-40mum is applied on the outer surface of the lower substrate to a thickness of 30-80mum by an electrostatic applying method. This unit is baked at a temperature of 350-400 deg. for 20-40min. Thus the lower substrate 10 is brought into contact tightly with the surface of the thermistor element 5. The lower substrate 10 is fused with the upper substrate 11 and both substrates are brought into contact tightly. Thus a reliable protecting film layer is formed.

Title: Jet fan
Inventor: NAGANO TSUKASA
IPC: F04D29/36
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To enhance the blowing efficiency of a jet fan with a simple constitution by providing a blade driving means by which the fitting positions of the respective blades are changed in accordance with the rotational direction of the blades, and also by specifying the chord-pitch ratio of the blade. SOLUTION: In the case where a jet fan is applied to a blowing device to be adopted for a road tunnel, an impeller 5 having variable blades or moving blades 3 whose fitting angle is variable is provided with a blade adjustable mechanism by which the fitting angle of each moving blade 3 can be changed to an optimum angle. Further, by which the fitting angle of each moving blade 3 can be changed in accordance with the blowing direction, and also the rotational direction of an electric motor 4 for driving the impeller 5 can be controlled in the normal or reverse direction.  When the moving blade 3 is reversed, the relational expression l<t, where l is the length of the cord of a blade and t is the pitch, is kept at any radial position of the moving blade 3; and since a centrifugal force is exerted to the moving blade 3 due to the rotation of the impeller 5, the shape of meridian surface of the moving blade 3 is formed in a three-dimensionally twisted shape. Since the length l of the cord of a blade is maximum at the root part, the chord-pitch ratio l/t at the root part of the moving blade 3 is set to be less than 1.

Filed: 1987-06-24
Abstract: PURPOSE: To reduce the deformation of a lead and to decrease a malfunction, such as a wire short-circuit by forming a section formed thinner than other lead over its longitudinal direction at the outer frame of a lead frame.  
     CONSTITUTION: A lead frame in which part of the outer frame 2 of a lead frame 1 is thinned is prepared. (This thinned recess 9 is treated by etching or the like). Then, a pellet 10 is bonded (placed) by Ag paste on a tab 3. Then, a wire 11 is bonded by thermal press-bonding or the like. Even if a force F as shown in the drawing is applied in this state, since the recess 9 is formed thinner than the other section, the recess 9 is deformed due to its weak strength. If the force F is absorbed by the deformation of the recess 9, the deformation of inner leads 6 can be reduced. Thus, the deformation of the wire 11 upon deformation of the inner leads can be decreased.
