Title: Surface hardening method for titanium and its alloy
Inventor: MUROI KATSUMI
IPC: C23C8/24
Filed: 1980-04-16
Abstract: PURPOSE:To provide hardness to the required part alone by performing local heating and blowing of gaseous nitrogen for a blank material simultaneously by means of plasma jets. CONSTITUTION:Mixed gases of nitrogen and argon are flowed from an operating gas passage 4 and gaseous nitrogen is flowed from a shielding gas passage 6 by using, for example, a plasma torch 1, to form an inert atmosphere, by which a blank material 7 is shut off from the atmosphere. Next, electric current is flowed between a tungsten electrode 2 and the nozzle 3, to generate plasma jets 8. The blank material 7 is heated by this, and at the same time, ionized nitrogen is ejected by the jets 8, whereby hardening reaction is accelerated. At this time, the jets 8 are maintained stably by keeping the nitrogen mixing rate of the operating gas 4 at <=30%. The flow rate of the operating gas is kept about <=10l/mm. in order to prevent the surface roughness of the blank material after the treatment from degrading.

Title: Waste containing box for clean room
Inventor: SHICHIEDA HIROYASU
IPC: B65F1/16
Filed: 1992-03-06
Abstract: PURPOSE:To prevent scattering of dust from a waste throw-in port to the outside by forming the charging port to be of a rotary slide type, and discharging the inside air through a gap between double containing boxes. CONSTITUTION:An inner containing box 1 for fixing a waste containing bag 6, and an outer containing box 2 for enclosing the inner containing box 1 are provided, and air is sucked and discharged from a gap between the inner containing box 1 and the outer containing box 2. A cover 4 of a waste throw-in port is of a rotary slide type, and a filter 5 is provided at a suction/discharge port 7. As air flowing from the waste throw-in port is a steady flow discharged from an air discharge port, dust generated when waste is thrown in follows the air flow to be collected by the filter 5, so clean air is discharged. Because the cover 4 of the throw-in port is of the rotary slide type, turbulence of air flow close to it can be restricted to the minimum, so scattering of dust into a clean room to contaminate it can be prevented.
