Title: Sheet material discharging device and image forming device
Inventor: OSHIDA HARUHISA
IPC: B65H29/60
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent various structural members from dew formation caused by the water vapor generated from a sheet material by selectively switching a sheet material with a fixed image, to plural sheet material conveying paths by means of a conveying path switching means to be discharged to plural sheet material discharging parts through plural sheet material feeding-out means. SOLUTION: A paper discharging flapper 115 is anticlockwisely rotated with a sheet material conveying path is switched to an upper paper discharging part 120 side, and its lower end part 115f is brought into contact with a rib 167c formed on a guide frame 167a of a lower guide member 167. The paper discharging flapper 115 closes a sheet material conveying path 169 toward a lower paper discharging port 127. Accordingly the flowing of the water vapor generated from a fixing device to the lower paper discharging part 125 side can be prevented even though the water vapor rises through a sheet material conveying path 170. Similarly, the water vapor diversed from the sheet material conveyed at an upper paper discharging path 120 side can be prevented from flowing to the lower paper discharging part 125 side.  Accordingly the dew formation and the wetting and wrinkling of the sheet material in accompany therewith can be prevented.

Title: Phase locked loop with low power feedback path and operationmethod
Inventor: HEKUTAA SANCHIESU
IPC: H03L7/18
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To attain the reduction of power consumption while keeping a lock state in a phase locked loop(PLL). SOLUTION: A PLL 10 has 124th and 228th feedback paths for matching the phase and frequency of a generated clock signal with an input reference clock signal. Two feedback paths are delayed and matched so that both the paths can be used for keeping 'lock of PLL'. However, power consumption on the 1st path is remarkably less than that on the 2nd route. A control circuit 22 selects which path is to be fed back through a multiplexer and disables the 2nd path when the route is not required.

Title: Video conference system
Inventor: OSHITA TAKASHI
IPC: G06F3/16
Filed: 1993-09-09
Abstract: PURPOSE:To smooth the video conference even when the video conference is implemented between different countries. CONSTITUTION:A multiplexer/demultiplexer section 1 receives a multiplexed signal for a video conference via a digital line and demultiplexes the signal into picture data and voice data or the like. The voice data are converted into an analog voice signal by a voice processing section 3 and inputted to a voice/character conversion section 9. The voice/character conversion section 9 converts the received voice data into corresponding character data, which are outputted to a sentence conversion section 10. The sentence conversion section 10 translates the character data into a predetermined language and the result is outputted to a picture processing section 8 as character data. The picture processing section 8 superimposes character data from the sentence conversion section 10 on picture data from the multiplexer/demultiplexer section 1 and the result is converted into an analog picture signal and it is outputted to a display device 4. Thus, the display device 4 displays the picture from the opposite party and a title corresponding to the voice signal.

Title: Rotating shaft seal
Inventor: HOSOKAWA ATSUSHI
IPC: F16J15/3252
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To reduce the deformation of a lip tip under a high pressure by elastically deforming a rubber seal member arranged closer to a fluid housing chamber over a seal element in the axial direction of a rotating shaft according to the increase in pressure of the fluid housing chamber, and pulling the lip tip in the direction separating from the rotating shaft. SOLUTION: When the pressure P of a high-pressure fluid is applied from a fluid housing chamber 33 side to the lip part 13 of a rubber seal member 5, the short cylindrical part 13a of the lip part 13 is elastically deformed so as to fit into the clearance between the rubber seal member 5 and a support metal fitting 12. The lip tip 13b of the lip part 13 is pulled along the inclined receiving surface A of the support metal fitting 12 in the direction separating from the rotating shaft 32 by a moving force Fx in the elastic deformation in the axial direction of the rotating shaft 32. Namely, a tensile force F1 acts on the tip angle part 14 of the lit tip 13b in the direction separating from the rotating shaft 32.  Accordingly, the force acting on the rotating shaft 12 is reduced by the potion of the tensile force F1, and the contact surface pressure of the lip tip 13b can be reduced to reduce the wear.

IPC: F04D13/08
Filed: 1994-10-14
Abstract: PURPOSE: To prevent air lock from occurring during the restarting of operation by a method wherein an air bleed piping communicated with a space in a casing at the periphery of an impeller, and a check valve having a valve hole closed at a given pressure in a pipe and opened at a given low pressure is located in the air bleed piping.
