Title: Method and device for grinding non-circular workpiece
Inventor: TERASAKI FUMITOSHI
IPC: G05B19/18
Filed: 1995-03-23
Abstract: PURPOSE: To improve shape accuracy of a workpiece by using a correction X/C axis data of calculating a speed, acceleration, change of the acceleration and a contact arc of the workpiece with a grinding wheel, at machining time, compared with each limit value, and decreasing a number of steps till going into within the limit value when any calculated value exceeds the limit value. CONSTITUTION: In the case of not exceeding a limit of acceleration change in X-axis acceleration change and C-axis angular acceleration change, a contact arc length is calculated in a contact arc arithmetic part 56 from a new X/C axis data and from a grinding wheel diameter stored in a grinding wheel diameter memory part 32. Next in the case that this obtained contact arc length exceeds a limit of a contact arc, a contact arc reducing process is performed, to again calculate the contact arc length of the new X/C axis data, so as to again perform a check for whether the contact arc length exceeds the limit or not. In the case of not exceeding the limit in this contact arc length, the new X/C axis data in this condition is stored as a correction X/C axis data in a memory part 35. The correction X/C axis data is prepared in one circumferential amount of a workpiece.

Title: Heat treatment with laser
Inventor: TAKASO MASASHI
IPC: C21D1/09
Filed: 1986-03-22
Abstract: PURPOSE:To enhance a cooling effect after heat treatment with a simple apparatus by forming a water film on the surface of a material, carrying out the irradiation or laser beams and the jetting of an inert gas and forming a water film again by the relative movement of a torch to cool the heat treated part. CONSTITUTION:A water film 5 is formed on the surface of a material 3 to be heat treated by retention or other method. Laser beams 1 are then irradiated on part of the surface of the material 3 from the concentric nozzle 4 of a torch. At the same time, an inert gas 6 such as Ar is jetted from the nozzle 4 to remove the water film 5 at the irradiated part. Since the torch is moving relatively to the material 3 at a prescribed speed, a water film is formed again immediately after the movement to cool the heat treated part. By this method, heat treatment with laser followed by forced cooling is carried out.

Title: Boiler for refuse incinerator
Inventor: ISHIZEKI KOJI
IPC: F23G5/48
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce corrosion of a water cooled wall tube of a radiation chamber and a superheater tube by blowing gas having a temperature of a specific range to a furnace and a boiler for agitation and mixture and controlling the temperature of an exhaust gas in front of the superheater to have a specific temperature. SOLUTION: Exhaust gas which has passed through a superheater 9, a neutralization processor 10 and a dust collector 1 is branched, passes through a recirculating fan 3 and is directed to an inlet 4 for a furnace/radiation chamber and an inlet 5 in front of the superheater. The exhaust gas to be recirculated has a temperature range of 100-300 deg.C, which results that in a condition where the exhaust gas is mixed until a sufficient agitating action is attained in the furnace and the boiler, no increase of unburned gas is invited unlike the conventional case where cold air is blown. Further, the refuse combusting boiler is provided with a means for controlling the temperature of the exhaust gas which is introduced to the superheater 9 from the inlet 5 at a given temperature range of 400-650 deg.C.  If the temperature is lower than 400 deg.C, it is difficult to heat steam and obtain given superheated steam, however, when the temperature exceeds 650 deg.C, ash in the gas is melted, thereby blocking the gas passage.

SOLUTION: A hot-melt adhesive composition heated, kneaded and extruded through an extruder is cut under cooling in a cooling water tank to form into a spherical form, wherein the temperature of the composition heated in the extruder is 125 deg.C or lower. It is desirable that the elastic modulus of the adhesive composition at the temperature in the extruder is 50-5,000 Pa and that the difference between the temperature of the composition heated in the extruder and the temperature of water in the cooling water tank is within 115 deg.C. The composition can be formed in a spherical form close to true sphere and excellent in fluidity by controlling the difference within 115 deg.C, even when the melt viscosity of the composition at 180 deg.C is 1,100 cPs or lower. This adhesive may contain a thermoplastic resin and, if necessary, additives such as a tackifier resin and a wax.
