Filed: 1988-07-18
Abstract: PURPOSE:To achieve a reduction in hysteresis, a higher speed of a sensor reaction and a stability of an output value by forming a moisture sensing film using a high polymer crystallized. CONSTITUTION:A lower electrode 2, for example, comprising platinum is formed at a top surface of an insulating substrate 1 comprising alumina, glass or the like. A moisture sensing film 3 is applied in lamination crossing the electrode and an upper electrode 4 comprising gold is formed thereon. Leads 2a and 4a are connected to the electrodes 2 and 4 to detect a change in an electric capacity value thereof with respect to a relative humidity of the film 3. This film 3 is produced as follows: 3-15g of cellulose acetate butyrate (CAB) containing, for example, a butyryl group 17% are prepared and dissolved into 100cc of a dioxane solution to obtain a CAB solution. The CAB solution thus obtained is applied on the electrode 2 by a spin coat method and then, dried in an atmosphere at a room temperature. After the work is preheated, it is heated for one-several hours at a temperature of above a glass transition point and below a melting point of a high polymer moisture sensing material to crystallize thereby obtaining a film 3 with a thickness of 0.5-10mum.

Title: Cooling fan for use in automobile
Inventor: SEKI NAKANAGA
IPC: F04D29/32
Filed: 1981-11-05
Abstract: PURPOSE:To keep durability of a cooling fan and to prevent drop of cooling efficiency by preventing reduction of air flow rate, by employing such an arrangement that the width of a ring connecting the tops of fan blades is 1/4- 3/4 to the height of a boss portion. CONSTITUTION:When a cooling fan 1 is turned, oblique air flow as shown by arrows in the drawing is produced by the function of inclination of a boss portion 2 and distortion of blades 4. In this connection, the width l of a ring 5 connecting the tops of each blade 4 is selected to be so small that it is 1/4- 3/4 to the height h of the boss portion 2. By employing such an arrangement, it is enabled to keep strength and durability of the cooling fan 1 as a whole. Further, since a hollow space having a particular width is formed on the opposite side of the tips of the blades 4, i.e., on the downstream side of the above oblique air flow, restriction to the oblique air flow imposed by the ring 5 when air flows radially of the blades 4 can be minimized. Therefore, it is enabled to prevent reduction of air flow rate and drop of cooling efficiency of the fan.

Title: Production of original
Inventor: SHINTANI YUJI
IPC: B41M3/14
Filed: 1988-07-18
Abstract: PURPOSE:To prevent forgery of a formed picture image by using a blank form coated on a base paper with a coating material consisting primarily of an inverse photochromic compd., and forming the picture image with a toner having a same color as a surface color of the base paper on the surface at the coating material side of the blank form. CONSTITUTION:An original is prepd. by using a blank form coated on a base paper 1 with a coating material 2 consisting primarily of an inverse photochromic compd., and then forming a picture image 3 with a toner on the surface at the coating material side of the blank form. The inverse photochromic compd. develops color different from the surface color of the base paper by visible rays, and the color is faded away to transparent color by ultraviolet rays. Accordingly, when the original is copied with a conventional copying machine, the contrast of the picture image part to the unimaged part is lost by the ultraviolet rays emitted from an irradiating light source even if an amt. of exposure is varied, preventing thus the transfer of the picture image. By this constitution, forgery of a formed picture image is prevented securely, preventing further surreptious use of information. At the same time, an original having superior durability of printed figures is obtd. easily.
