Title: Dynamic pressure fluid bearing type scanner unit
Inventor: ASADA TAKAFUMI
IPC: F16C17/10
Filed: 1986-04-02
Abstract: PURPOSE:To prevent a lubricant from being scattered to stick on the surface of a polygon mirror and to obtain a compact dynamic pressure fluid bearing with high rotation accuracy by providing a screw groove in the inner periphery of a disk. CONSTITUTION:When a motor stator 19 is powered on, a motor rotor 17 begins to rotate together with a rotating shaft 12, the disk 13, and the polygon mirror 16. Consequently, the pressure of the lubricant 21 is increased through the pumping operation of herringbone grooves 11B and 11C and the spiral groove 14A of a thrust member 14 and the rotating shaft 12 rotates without contacting a fixed sleeve 11A nor the thrust member 14. When a dynamic pressure fluid bearing type scanner unit is put in operation continuously for a long time, the supplied lubricant 21 is scattered in the herringbone grooves 11B and 11C and about to spread toward the polygon mirror 16 along the inner peripheral surface of the disk, but the lubricant is pushed back upward by a screw 13A with pumping force, so that it is prevented from sticking on the polygon mirror 16.

Title: Ink feeder
Inventor: KOTOU HARUHIKO
IPC: B41J2/19
Filed: 1980-06-06
Abstract: PURPOSE:To prevent the inflow of air bubble into a printing head by means of an air trapping chamber having a porous member and an ink channel inside provided in an ink passage in an ink jet recorder. CONSTITUTION:As an ink 25 in a cartridge 18 is consumed, air flows in from an inlet 24 and is drawn into a porous member 24. However, when it moves to a head 11 for some reasons and reaches a capillary tube 20, the resistance value will be infinite between electrodes 21 and 22. So, changes in the resistance value are detected to prevent the inflow of air into the head 11. Air bubble generated at a part closer to the head 11 from the electrode 22 is blocked with the porous member 14 and accumulates in the air trapping chamber 15. As a groove-shaped ink channel 16 is provided in the air trapping chamber 15, the ink reaches the porous member 14 due to a capillary force regardless of air bubble 40 if any. Thus, the air bubble 40 will not pass through the porous member 14.

Title: Multiplex demodulation method
Inventor: MATSUSHITA HIROSHI
IPC: H04N5/60
Filed: 1980-06-06
Abstract: PURPOSE:To accomplish the demodulation method of television voice multiplex with a low distortion factor, by obtaining a signal difference through the application of a composite voice multiplex signal and a main voice signal to the input side of a differential amplifier respectively and picking up a subvoice signal through the demodulation of the signal difference using an FM detector. CONSTITUTION:For example, a composite voice multiplex signal Fcomp from an input terminal 1 is an FM+FS signal via a frequency trap 2 except a control signal FQ of 3.5fH and inputted to one of a differential amplifier 3. The main voice signal FM only is picked up and coupled to another input via an LPF4 of 15kHz and also coupled to a main-, subswitching circuit 5. Further, at the output of the differential amplifier 3, a subchannel signal FS as an FM signal eliminated with the amplitude modulating component and the amplitude overlapped component is obtained, and it is picked up as subvoice signal Fs by demodulating it at an FM detector 6. Thus, a subvoice signal with a low distortion factor and less cross talk from the main channel and ease of IC formation is accomplished without using the expensive band pass filter.
