Title: Method for electric discharge machining
Inventor: MIYAHARA HITOSHI
IPC: B23H7/20
Filed: 1979-10-26
Abstract: PURPOSE:To manufacture an angled part as sharp as possible in machining the edge form of an article to be machined by an electric discharge machining by constituting the device so that an electrode moves a circular-arc machining route around a position apart from the tip of the angled part as a rotational center. CONSTITUTION:The electrode 2 connected to one pole of a power source for electric discharge machining moves from a position a to a position b along a center line 4 from the direction shown by an arrow A, while generating electric discharge between the same and an article 1 to be machined connected to the other pole of the power source. The position b is the position of the electrode 2 taken thereby correspondingly when the upper side surface of the tip part 5 is machined by electric spark. Next, the electrode 2 moves from the position b to d via c. This section of the route is a semicircular-arc trail around a point 7 as a center located apart from the tip part 5 by a distance L on the extension of the bisector of the angled part 3 and also is the machining route. In addition, the distance L may well be larger than a discharge gap l. In this way, the edge of the article can be machined into a sharp form.

Title: Hot-air heater
Inventor: MORIYA YOSHIFUMI
IPC: F23N5/20
Filed: 1988-06-06
Abstract: PURPOSE:To sharply reduce the odor carried by the hot air sent into a room through the outlet by reversing a convection blower, in releasing into a room the exhaust gas produced by the combustion following the ignition, so as to precede the release by its heat exchange with oxidation catalyst and next by adsorption of the disagreeable odor components thereof by adsorbent provided at the back of the heating apparatus and by rotating the convection blower in the normal direction after the activity of the oxidation catalyst has become heightened. CONSTITUTION:A combustion blower 8 sends air into a vaporizing cylinder 10 in the manner of pre-purge at the start; an igniter 4 is energized and then kerosene is fed into the vaporizing cylinder 10, vaporized, and mixed with the combustion air, and the fuel mixture is ignited as it comes over the flame-hole surface of a burner 2. By reverse rotation of a convection blower 1 the exhaust gas resulting from the combustion is made to rise inside a combustion cylinder 5 and undergo heat exchange with oxidation catalyst 6, whereas the catalyst is activated. The exhaust gas, whose temperature has thus been lowered, undergoes removal of the disagreeable odor components by adsorption by adsorbent 11 provided at the back of the heating apparatus before it is released into the room. When the oxidation catalyst 6 has become active, the convection blower is made to rotate in the normal direction so that the diagreeable odor components of the hot air is reduced when it is sent into the room through the outlet 9.
