Title: Shutter closing mechanism of recording medium driving device
Inventor: OTSUKI AKIRA
IPC: G11B17/04
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a shutter closing mechanism of a record medium driving device capable of surely performing the opening/closing operation of a shutter by preventing the positional deviation of a closing member. SOLUTION: Since a projecting part K1 of a closing member K is positionally controlled by being fitted to an opening part 13K of a holder 13, the positional deviation in the direction of the thickness Z of a disk case C is prevented. Therefore, the projecting part K1 is slid on the side surface of the disk case C without entering a guide groove C2 of the disk case C and surely inserted into a holding hole G1 of a shutter G. The projecting part K1 does not hook to the shutter G, etc., accordingly, a sliding load in the projecting part K1 is not increased and the inserting and ejecting operations of the disk case C become smooth. Also at the time of ejection, the disk case C can surely be ejected in the state that the shutter G is closed.

Filed: 1978-11-09
Abstract: PURPOSE: To perform an efficient and uniform internal coating by a method wherein a glass bulb is perheated, then voltage is applied across an electrode surrounding the preheated bulb and a powder injection nozzle in unheated ambient condition.  
     CONSTITUTION: Prior to an electrostatic coating application, a glass bulb 1 is uniformly perheated to about 350°C by use of a burner 3. The supporter 2 is used to hold the glass bulb 1 into which a powder injection nozzle 3 is inserted, all without being heated. Then, a high voltage is applied across an electrode 4 surrounding the bulb 1 and the nozzle 3. The nozzle 3 is moved backward, while injecting a fluorescent powder to perform electrostatic coating. Because of wide space between the nozzle 3 and electrode 4, a uniform fluoresecent coating layer is formed. The preheating of the bulb allows the use of plastic meterial as the supporter 2 which is inexpensive and has a good workability and strength.
