Title: Motor fan
Inventor: YAMAOKA MIKIO
IPC: F04D29/28
Filed: 1983-09-28
Abstract: PURPOSE:To achieve sufficient dynamic balance as a rotary body while to reduce vibration and noise thus to stabilize the performance, by folding the outer circumferential end of front shroud upward to form an annular side wall thus adjusting the weight balance of impeller. CONSTITUTION:An impeller 11 is formed with a front shroud 16, rear shroud 17 and a plurality of blades 18 secured between both shrouds 16, 17. Weight balance of impeller 11 is adjusted by folding the outercircumferential end of front shroud 16 entirely upward to form an annular sidewall 19 then forming a notch 19' in it. Consequently, sealing function of annular groove 20 and annular sidewall 19 will block air flow through the gap between fan casing 10 and impeller 11 to the suction port 21 of fan casing 10. While dynamic balance as a rotary body can be achieved sufficiently to never cause differential air output of each motor fan.

Title: Ignitor
Inventor: MIYANAKA MOTOSHI
IPC: F23N5/20
Filed: 1981-11-13
Abstract: PURPOSE:To prevent ignition from occurring for a period of time until electric charge of a condenser of an ignition circuit is discharged after an operation switch is turned off, by giving no gate signal to a thyristor of the ignition circuit. CONSTITUTION:Resistor 42, which becomes a load and controls charge voltage  of a capacitor 23 while action of an ignitor circuit is suspended, discharges electric charge of the capacitor 23 when an operation switch 2 is turned off. When the operation switch 2 is turned off, the electric charge of the capacitor 23 is discharged. On one hand, a transistor 35 is turned on by a capacitor 41. A period of duration for this ''ON'' state is set at a longer time than that to be required for discharge of the capacitor 23 through the resistor 42. In this way, occurrence of ignition ignition at the time of turning the operation switch on is  prevented.

IPC: F21V29/00
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To perform effective cooling without causing a decrease in light emitting efficiency as the result of adhesion of metals or metallic compounds by introducing cooling air in such a way that it is not directed to the light emitting region of a transparent partition which corresponds to the space between first and second electrodes. SOLUTION: Cooling air stream is introduced into a light source device from an opening 2c. In that case, the air stream is directed so that on a transparent partition 1A defining a lamp 1, the air stream does not enter a light emitting region 11 between electrodes 1B, 1C but selectively cools an electrode region 11A corresponding to the electrode 1B and a region 11B corresponding to the electrode 1C. As a result of this selective cooling, the temperature rise of the entire light source device is restrained, and at the same time the problem of adhesion of metals or metallic compounds to the emitting region 11 between the electrodes 1B, 1C, most critical to the performance of the light source device, is solved; i.e., even if adhesion of metals or metallic compounds occurs, it occurs in the electrode regions 11A, 11B adjacent to the region 11 and not in the region 11.
