Title: Electrophotographic developing device
Inventor: KOBAYASHI JUNJI
IPC: G03G15/09
Filed: 1985-05-17
Abstract: PURPOSE:To crush flocculates of toner on the peripheral surface of a developing sleeve sufficiently with a large physical force by providing a magnetic member for developer agitation opposite the peripheral surface of the developing sleeve while a gap smaller than the thickness of a developer layer formed on the peripheral surface of the developing sleeve is left. CONSTITUTION:The developing sleeve 4 is provided opposite the surface of a photosensitive drum 1 while a gap is left. The magnetic member 7 for developer agitation is provided over the peripheral surface of the developing sleeve 4. Lines of magnetic force of a magnetic field between a magnet roller 5 and the magnetic member 7 are changed in direction abruptly in a short time according to the rotation of the magnet roller 5. Thus, a developer 3 is agitated magnetically and receives a relatively large physical force. Consequently, flocculates of toner having large a flocculating force are crushed sufficiently before being carried to a development area.

Filed: 1990-04-24
Abstract: PURPOSE:To achieve cost reduction by reducing the number of parts and to miniaturize a recording apparatus by making name the drive source operating the ribbon feed means of a ribbon adaptor and the drive means taking up the ribbon of a ribbon cassette with each other. CONSTITUTION:When a ribbon motor 5f1 is reversely driven, a correction cam 5e is moved in the direction shown by an arrow (e) and the cam surface 5e1 thereof pushes the lever part 5b2 of a feed lever 5b in the direction shown by an arrow (b) and a correction ribbon 1 is taken up by a taking-up spool 3. When the ribbon motor 5f1 is forwardly driven, the driving force of the motor 5f1 is transmitted to a taking-up shaft 12j through a ribbon gear 12k and a taking-up core 8d is rotated to draw out an ink ribbon 7 from a supply core 8c to take up the same. As mentioned above, since the taking-up of the ink ribbon 7 of a ribbon cassette B and the feed-out of the ribbon 1 of a ribbon adaptor A are performed by the driving force from the same drive source, the number of the parts of a motor are reduced and cost reduction and the miniaturization of the apparatus can be achieved.

IPC: G11B5/84
Filed: 1996-04-26
Abstract: PURPOSE: To prevent the occurrence of a head crash by providing the surface of a substrate with fine grooves and grinding the projecting parts built up and formed by the formation of these fine grooves by the prescribed quantity from the peak parts thereof as a second grinding stage. CONSTITUTION: A substrate is rotated by a motor 3 and simultaneously, a first working head H1 is oscillated at the set oscillation amplitude by a motor 16 for oscillation when a substrate working device is turned on. Grinding tapes 4a, 4b are then taken up under specified force by a grinding tape driving device 7 and the pressurizing force on the substrate is so adjusted as to attain the set first pressurizing force. The fine grooves are formed on the surface of the substrate 2 by the grinding tapes 4a, 4b if a reciprocating moving base 22 is moved forward and backward by a reciprocating moving means R.  In such a case, a controller 17 is capable of maintaining the specified pressurizing force of contact rollers 8, 9 on the substrate 2 by controlling a motor 14 regardless of the fluctuation in the tension of the grinding tapes 4a, 4b and, therefore, the small and uniform fine grooves are formed.

IPC: B25J5/00
Filed: 1984-05-26
Abstract: PURPOSE:To enable low motive power to cause a creeping robot (creeping conveyance robot) to surely creep, by coupling wheels through one-way clutches to both the ends of a creeping shaft whose swing anle is variable, and by swinging the creeping shaft. CONSTITUTION:After a pivot 31 on a planetay pin is positioned at a distance of lalong a guide groove 39 from a rotary shaft 17 located at a distance of L from a swing shaft 3, a step motor is driven to rotate a rotary reset 24 to swing a creeping shaft 4 by an angle of theta first. At that time, since a right and a left front wheels 5 can be rotated only forward through the action of one-way cluthes W, the right wheel 5R is first moved forward by the angle of theta about the left wheel 5L. The pivot 31 is rotated while passing through positions 31', 31'', 31''', 31 in the guide groove 39 along with the rounds of rotation of the rotary rest 32, so that the wheels 5R, 5L are alternately rotated forward about each other. Each creeping step by an angle of 2theta is thus effected.

Abstract: PURPOSE:To reduce the generation of NOX by blowing a combustion waste gas from a conbustion chamber into a combustion chamber through a blow-off port formed on the side wall of the combustion chamber after passing the same through a temperature reducing tower and a dust collector. CONSTITUTION:A combustion waste gas 16 drawn out of a flue 15 passes through a dust collector 18 from a temperature reducing tower 17 and is exhausted into the atmosphere by means of an exhaustbon 19. However, a part of the waste gas 16 is supplied from a gas supply duct 14 into an air cooling chamber 12 by a wast gas circulating fan 20. the waste gas is blown into the combustion chamber 2 from a blow-off port 11 via a hole 13. As a result, since the temperature of the flame is lowered, the nitrogen content becomes difficult to be oxidized. Further, since surplus oxygen which is a source for generating NOX is not supplied in the combustion chamber 2, it is possible to suppress generation of NOX.

Title: Intermittent recorder
Inventor: KANDA SHIYUUHEI
IPC: G11B5/027
Filed: 1981-07-10
Abstract: PURPOSE:To obtain a voice output of the normal level even in a double-speed reproduction mode, by driving a magnetic tape in the same speed as the traveling speed of the magnetic tape in the recording mode and performing a frame feed reproduction at a double speed. CONSTITUTION:A switching transistor TR21 is set at a recording circuit of the video signal to give the bypass to the video signal toward an earth. That is, the video signal to be led out to an output terminal of a video signal processing circuit 22 is bypassed toward the earth when the TR21 is turned on. When the TR21 is turned off, the video signal led out to the output terminal of the circuit 22 is recorded on a magnetic tape via a rotary transistor TR23 and a video head 24. Thus a magnetic tape on which only the control signal is recorded is obtained by applying the positive voltage to the base of the TR21 to turn the  TR21 on. Such magnetic tape is driven by a magnetic tape driving means, and  the control signal is reproduced through a control head. Then the degree of  delay is controlled for the monostable multivibrators 11 and 14.
