Title: Automatic cap dropping apparatus
Inventor: MIURA YOSHIO
IPC: B65G59/06
Filed: 1978-05-17
Abstract: PURPOSE: To provide an auotmatic cap dropping apparatus, which comprises a first stopper to be inserted into a hole formed in a guide tube and a second stopper to be inserted into a thru-hole also formed in the guide tube, wherein a hole is formed in the second stopper itself for passing a cap therethrough while other cap made of resilient material is forced onto the wall of said guide tube by the first stopper, whereby caps can be dropped intermittently in the guide tube.  
     CONSTITUTION: A plurality of caps 1 are dropped successively in hollow space 5 in a guide tube  4 which is supported on base 3. Coil springs 6 are fitted at the upper and the lower ends of guide  tube 4. At intermediate portions of the tube 4, there are formed a hole 7 and a thru-hole 8. The  hole 7 does not extend laterally through the opposite side wall of guide tube 4 but thru-hole 8 is  extended therethrough deeply to the inside of base 3. Stoppers 9, 10 fitted respectively in the holes  7, 8 are connected to driving source 12 via rod 11. As a plurality of caps 1A, 1B, 1C are dropped  successively in guide tube 4, the foremost cap 1C is stopped by stopper portion 10B, but in this  state, stopper 9 is not inserted into the mating hole 7. However, when the rod 11 is moved further  in the direction X', stopper 9 also enters into hole 7 and forces cap 1B onto the inner wall surface  of tube 4. In the above while, cap 1C is allowed to drop through hole 10A formed in stopper 10  itself, and then rod 11 is retracted in the direction X. By repeating the above procedures, caps can  be fitted automatically on wire.

Filed: 1978-05-17
Abstract: PURPOSE:To enable solder hot dipping of high quality to be performed without using a flux in a hot dipping apparatus by applying ultrasonic vibration to spouting molten solder and by covering the molten solder surface with an inert gas. CONSTITUTION:Diode 51 is attracted by magnetism to each storage channel 30 of holding block 27 fixed to chain 25, and lead 50 is continuously dipped in molten solder spouting through inlet 52 of cover 47 to coat the lead part with molten solder. At this time, nitrogen gas is always supplied into cover 47 through inert gas supply pipe 54 to cover the molten solder surface with the gas. Molten solder rises from the lower part of guide 44 and overflows from the upper edge of guide 44. Accordingly, there is no oxide on the surface of the spouting molten solder and in the interior thereof, so bright solder hot dipping of high quality is performed.

Title: Tape driver
Inventor: SASAKI KENJI
IPC: G11B15/28
Filed: 1984-03-27
Abstract: PURPOSE:To drive accurately and assuredly a capstan when a tape is driven at a low speed and to reduce the noise produced by a revolving gear in a high- speed drive mode of the tape, by providing the 1st and 2nd control members which control the revolutions of the 1st and 2nd rotors and the 1st and 2nd outer gears. CONSTITUTION:In a low-speed driving mode of a tape, the signals are sent to a servo motor 11 and an output shaft 12 is revolved clockwise. The revolutions of the shaft 12 are transmitted to a capstan 1 from the 2nd sun gear 31 via each gear. A pinch roller 5 is pressed to the capstan 1 by a spring, and a magnetic tape held between the roller 5 and the capstan 1 is driven at a fixed speed with revolutions of the capstan 1. While in a high-speed driving mode of the tape, the rotational frequency of the 1st sun gear is set at N21. At the same time, the 1st planetary gear 22 revolves round the gear 21 with a rotationary frequency N25. Therefore the engagement rotational frequency between gears 21 and 22 is equal to (N21-N25) with the reduction equivalent to the share of N25. Thus the noise produced by the engagement are reduced by a degree equivalent to the engagement rotational frequency equal to N25 compared with the rotational frequency N15=Nout=N21 of a capstan gear 15.

Filed: 1994-03-29
Abstract: PURPOSE:To correctly set the display of the film use state of a film cartridge and to prevent the double exposure of the film in a camera using the film cartridge. CONSTITUTION:The pawl 34a of a spool driving shaft 34 is arranged at a position which is not aligned with the position of the groove 12b of a spool 12 at a rotational angle position where the index 12a of the cartridge 10 indicates 'partially exposed' and the position of the groove 12b of the spool 12 at the rotational angle position where it indicates 'already exposed'. Thus, even when the cartridge 10 containing a film in the state of 'partially exposed' or 'already exposed' is tried to be housed in a cartridge housing chamber, the pawl 34a abuts on the end face of the cartridge 10 so that the cartridge 10 projects from the cartridge housing chamber in the axial direction and a back cover 73 can not be closed, thus, only the film cartridge containing the 'unused' film is received in the cartridge housing chamber.

Title: Scanning type charged particle beam device
Inventor: MIZUNO FUMIO
IPC: H01J37/244
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of an image contrast resulted from electric charge by setting a minimum potential on a secondary electron passage higher than a potential of a sample table. SOLUTION: A secondary electron passage is covered with a cylindrical electrode 12, to which a positive voltage of about several tens volt is applied. When a potential of the applied positive voltage is higher than a sample surface potential, a potential barrier on the secondary electron passage disappears. Consequently, even when the surface of a sample 6 is electrically charged at a positive potential, all secondary electrons can reach a secondary electron detector 10. Therefore, variations in potential of a minimum potential portion of the secondary electron passage enable a voltage contrast to be observed.
