Title: Method and device for fur brush cleaning
Inventor: KATOU KAZUYUKI
IPC: G03G21/10
Filed: 1980-10-13
Abstract: PURPOSE:To achieve effective cleaning by changing the fur brush turning speeds of a fur brush cleaning device corresponding to the density of residual toner on a photosensitive drum. CONSTITUTION:An original electrostatic latent image formed by an exposure device 3 is developed into a toner image by a developing device 4, and the toner image is transferred to transfer paper 7 by a transfer separator 6. Residual toner on the drum is destaticized by a destaticizer 8 and cleaned by a fur brush cleaning device 9, but if the transfer paper jams on a carrier device 10, an untransferred toner image remains after the transfer paper is removed, so the density of the residual toner is detected by a density detector 11 to change the turning speeds of a fur brush, thus performing the cleaning smoothly. A timer may be provided to turn the fur brush at a high speed only for a constant time after the transfer paper is ejected.

Title: Cleaning apparatus
Inventor: NAKAHIRA SHIRO
IPC: C02F3/10
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To obtain high cleaning capacity by providing the flows of water flowing in the upper of connected water tanks and the flows of water circulated in the water tanks. SOLUTION: Five aerobic contact tanks 4 are connected to an anaerobic sedimentation tank 3 and a final sedimentation tank 5 is connected finally. The partition walls 6 separating the respective tanks 3, 4, 5 are made slighly lower in the upper end than the surface of water and air diffusers 7 are provided to the bottom parts of the aerobic contact tanks 4 and the tanks 3, 4 excepting the final sedimentation tank 5 are packed with string-like contact oxidizing deices 9. Herein, since the partition walls 6 separating the tanks 3, 4, 5 are made slightly lower in the upper ends than the surface if water, water flows horizontally in the upper parts of the tanks 3, 4, 5 and air bubbles discharged from the air diffusers 7 rise in the aerobic contact tanks 4 to generate circulating flows.  Since the stagnation times in the tanks can be made long, it is unnecessary to make water tanks large and the contact time with the string-like contact oxidizing devices 9 becomes long and pulluted water can be efficiently cleaned.

Title: Paper releasing mechanism
Inventor: TASHIRO JIYUNICHI
IPC: G03G15/14
Filed: 1978-11-20
Abstract: PURPOSE: To release the paper effectively, by providing a pawl to release the paper from the recording medium, and guide roller to send out the paper to the fixing part in cooperation with feed roller, and providing springs so as to cause the pawl to contact with the recording medium and guide roller with the feed roller, respectively.  
     CONSTITUTION: A pawl 12 is pushed in the direction of arrow (1), being rotated around a shaft 13 by a spring D provided on the shaft 13. Therefore, the end of the pawl 12 tightly contacts with a recording drum 1, and the paper 6 is securely released from the recording drum 1. Since a paper feed guide roller 11 is press-fitted to a paper feed roller 10 by the spring D through the paper 6, as the paper 6 moves on, the paper feed guide roller 11 rotates on its axis C, and also runs on the circumference of radius BC around B in the direction of arrow (2). Hence, paper is fed securely. Since the surface of recording drum 1 is pressed against the pawl, the printing region is not reduced.

Abstract: PROBLEM TO BE SOLVED: To effectively release the heat generated by a highly heat generating element to a heat releasing section by attaching a heat releasing section comprising a fan to an external wall of an electronic apparatus mounting a highly heat generating element and thermally coupling the highly heat generating element and heat releasing section with a heat transfer section. SOLUTION: A heat releasing section 4 comprising a fan 3 is mounted to an external wall of an electronic apparatus mounting a highly heat generating element 1 to thermally couple the highly heat generating element 1 and heat releasing section 4 with a heat transfer section 5. Heat generated by the highly heat generating element 1 is transferred to the heat releasing section 4 mounted on the external wall of the electronic apparatus via the heat transfer section 5. The heat releasing section 4 comprises a fan 3 and temperature rise at the heat releasing section 4 is forcibly lowered by air with the fan 3. The heat transfer section 5 is formed of a material having good heat conductivity. It is preferable to use a heat pipe 50 having very good heat conductivity.  In this case, a contact member 50b having good conductivity is loaded to the contact area with the heat releasing section 4 or highly heat generating element 1.

Title: Opening-closing detection structure in switchgear
Inventor: KANESHIRO TATSUZO
IPC: E05B65/00
Filed: 1994-06-24
Abstract: PURPOSE:To enable an accurate detection of opening and closing by manufacturing an operating member operating a detecting section and a member locking an opening- closing member in the same part, and mounting the operating member on a lock lever. CONSTITUTION:A detection projecting piece 25b is formed integrally to a lock lever 25 while being adjoined to a hook section 25a. When the hook section 21a of a lock lever 21 is engaged with a pin 7a and an upper case 3 closes a lower case 2, the hook section 25a of another lock lever 25 is also engaged with a pin 7b simultaneously. The detection projecting piece 25b is intruded into the recessed section of a detecting section 27a at that time, and the closing of both cases is detected optically. The positional relationship of the detection projecting piece 25b and the hook section 25a is not displaced due to an error in assembly because the detection projecting piece 25b is formed to the lock lever 25 consisting of the same member as the hook section 25a interlinked with the pin 7b, and the positional relationship of the detection projecting piece 25b and the hook section 25a is not displaced due to an error in manufacture because the detection projecting piece 25b is formed adjacently to the lock lever 25 integrally, thus preventing erroneous detection by the detection projecting piece 25b.

In this case when the signal (b) is higher, H is added to a gate circuit 6 and when the signal (b) is lower, L is added to a gate circuit 6. Only in case of H, a signal (e) sent from a circuit 1 is added to a counter 7 for serial-parallel conversion as a signal pulse (f). A switch 9 for time division multiplex is switched by output of a frequency divider 2 and negative voltage which is larger than the maximum value of the input signal is supplied to analog signal input terminals 1 and 2. A positive voltage which is larger than the maximum value of the input signal is alternately added to the analog signal input terminals 3-16 to output to the amplifier.

Title: Information transfer system
Inventor: TANNO CHIAKI
IPC: H04Q3/54
Filed: 1978-11-22
Abstract: PURPOSE:To decrease the number of the relays by securing the common use for the connection relay berween the originating register and the common control unit and the calling subscriber information transfer control relay. CONSTITUTION:When the called subscriber information is stored REG1 in originating register OR, common control unit start contact ms<0> closes to operate relay CNA. And circuit REG1 is connected to common control unit MKR. In unit MKR connection identification relay HI between the called subscriber and the intra-office trunk operates first and then control relay HIC operates. Thus circuit REG1 is connected to reception relays R0-R7 to secure the connection between the called subscriber and the intra-office trunk. When the connection is over, lelays HI and HIC release. After this, relay HA between the calling subscriber and the intra-office trunk operates to actuate relay CN, and thus the connection is secured between calling subscriber information storage circuit REG2 and the reception relay. And the calling subscriber storage position information is transferred to give connection between the calling subscriber and the intra-office trunk. In such constitution, the number of relays can be decreased.
