Title: Excitation module
Inventor: HIRAMA HIDEO
IPC: H04R1/00
Filed: 1988-08-10
Abstract: PURPOSE:To improve the life of bearings and to reduce cost by using a DC solenoid in place of a motor and linearly oscillating an excitation weight which generates oscillation back and forth along a shaft. CONSTITUTION:Current flows to a driving coil 5 when a power source is supplied to a power source line 11. Since the coil 5 is of right-hand winding, a magnet 8 integral with an oil-impregnated bearing 7 is attracted in a left direction by a magnetic field generated by the coil while a spring 2 is shrunk by said bearing. A detection coil 6 generates a reverse voltage by the inductance changed by an excitation unit 78 advancing into the coil when the magnet comes sufficiently to the left side. As a result, a transistor(TR) 15 is turned off and the current does not flow any longer to the coil 5. The unit 78 is returned to the right side by the spring 2. The coil 6 does not act any longer and the TR 15 turns on when the magnet is returned to the right side. The coil 5 is again driven and the movement that the unit 78 begins to move to the left side is repeated. The oscillation of the unit 78 is transmitted through a case to the outside.

Abstract: PURPOSE:To make each tool to be returned from a spindle restorable all to its original housing position and fixed address type tool selection performable, by setting the number of socket housing parts of a magazine down to at least N+1 to the working tool number N. CONSTITUTION:After toll changing, since an empty socket 25, as a tool T1 is pulled out, is left behind in an engaging fork 47, it is necessary to put the tool back to a tool magazine 16, but a holder of a tool T commanded as the first is necessary to be emptied for a working tool T at the final process. Therefore, after the magazine 16 is indexed so as to cause the holder at the (N+1)th address to be situated in a tool setting position P4, the fork 47 is retracted to some extent, and when the socket 25 is put back to the position P1, the socket 25 is engaged with the holder 24 at the (N+1)th address, and since a member 63 comes into contact with a separation preventing member 51, this member 51 turns round counterclockwise against the pressing force, whereby engagement between an engaging groove 53 and a pin 54 is set free. Therefore, any obstacle in a traveling route of the socket 25 is brought to nothing as well as a chain 23 of the magazine 16 is indexed so that the tool is restorable to its original position.

Title: Paper feeder
Inventor: AKAHA FUJIO
IPC: B41J13/00
Filed: 1987-08-11
Abstract: PURPOSE:To obtain a paper feeder ensuring that the papers are fed separately one by one even if the thickness of the papers is changed, by providing a friction member having a friction coefficient which is smaller than the friction coefficient of a paper feed belt and larger than that between the papers. CONSTITUTION:When the leading edge of a paper 2 abuts against a separation board 6 due to the rotation of a paper feed belt 3, the paper 2 is made to change in direction shightly upwards. If at this time a plurality of sheets of the papers 2 were fed, the paper abuts against the separation board 6 from the bottom. The friction coefficient between the paper 2 and a synthetic rubber 6a as friction member on the separation board 6 is higher than that between the papers 2; thus, the paper 2 is fastened at the time of abutting against the separation board 6. After that, the papers 2 are successively fastened from the bottom in a similar manner, and lastly the paper 2 on the top abuts against the separation board 6. At this time, however, the higher friction coefficient between the paper 2 and the paper feed belt 3 than that between the paper 2 and the synthetic rubber 6a as friction member allows the paper 2 to be fed without being fastened on the separation board 6.
