Title: Production of corrosion resistant hard film
Inventor: CHIBA YUJI
IPC: C23C14/24
Filed: 1992-02-28
Abstract: PURPOSE:To provide the process for production of a hard film by a physical vapor deposition method which can improve corrosion resistance by decreasing the pinholes in the film. CONSTITUTION:The bias voltage impressed to a metallic substrate is set between -500V and -2000V and metal ions of Ti, Zr, Hf, V, Nb, Ta or Cr used for film formation are implanted at last once to the hard film during the formation of the hard film, by which the product is obtd. in the process for forming the hard film of at least one kind among the nitride, carbide or carbonitride of Ti, Zr, Hf, V, Nb, Ta or Cr on the metallic surface by the physical vapor deposition method. The resulted product is subjected to a ferroxyl test in accordance with JIS (Japanese Industrial Standards) H 8663 and the corrosion resistance is evaluated by the density of pits. The results of this test reveal that the corrosion resistance is greatly improved as compared to the case where the product is not subjected to the ion implantation treatment.

Title: Voltage holding device
Inventor: MINAMI EIJI
IPC: G11C27/00
Filed: 1982-05-11
Abstract: PURPOSE:To hold the voltage stably and for a long period of time, by detecting the potential of a capacitor and then feeding it back to a terminal at the other side of the capacitor after inversion and amplification.

Title: Fire resistant locker
Inventor: SHIMAMOTO KIMIHITO
IPC: E05G1/026
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To protect an article from flames and heat at the time of a fire by providing a radiating hole for diffusing heat generated from the article stored in a body, and a fire resistant closing means for automatically closing the radiating hole at the time of the fire, in suitable parts of a body or a door. SOLUTION: At the normal time, heat generated in a server 6 is diffused from a radiating hole 7, so that a computer can be used without hindrance in the state of the server 6 being stored in a fire resistant locker, and theft preventiveness equivalent to a safe can be ensured by locking the lock of a door. In case of the generation of a fire, a temperature fuse bar 22 is softened or melted by heat, so that a shutter plate 19 falls automatically to close the radiating hole 7. Flames and hot air do not therefore enter the fire resistant locker from the radiating hole 7 so as to protect the server 6 from the fire. Fire fighting water and sprinkler water are also prevented from entering the fire resistant locker. An article such as the server can therefore be used normally without shutting heat up inside the fire resistant locker.
