Title: Image forming device
Inventor: HORI HIROAKI
IPC: G05D23/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To form an image with excellent fixability on both front and back surface by controlling the fixing temperature to be linked to a paper temperature after fixing. SOLUTION: An image is formed in such a manner that an electrostatic latent image corresponding to an image to be formed is formed on a photoreceptor 17 and is developed with toner, transferred to paper P and fixed by a fixing part 22.

A temperature detection sensor 29 is provided on the carrying path L5 between the fixing part 22 and the paper ejection part 6. In response to the temperature detecting operation of the sensor 29, the fixing temperature Tf is altered based on the result of the comparison of a paper temperature Tp detected by the sensor 29 with a specific reference temperature Tn.

Title: Grease sealed bearing
Inventor: TAMADA KENJI
IPC: F16C33/62
Filed: 1991-07-25
Abstract: PURPOSE:To prevent specific peel to be caused by the material of a bearing ring in a grease sealed bearing of electric equipment of automobile by making a fixation side bearing ring of the bearing of the steel including Cr at a predetermined %. CONSTITUTION:An outer ring 2 is made of the steel including Cr at 1.5-6%. An inner ring 1 can be made of the same material, but in consideration of cost, the inner ring 1 is made of the general bearing steel. Since the steel including Cr at 1.5-6% forms the strong and dense Cr oxide film, which has an effective thickness, on the metal surface, the rolling surface of the bearing is non- activated to restrict decomposition of the grease. Intrusion of hydrogen to be generated by decomposition of the grease into the steel is also prevented to prevent specific peel.

Abstract: PURPOSE:To provide a carrier which has high electric resistance, stable triboelectrostatic charge quantity and partial electrical conductivity and has excellent durability as well by coating carrier core particles with a resin and fixing fine inorg. particles treated with a coupling agent having the electrostatic charge polarity reverse from the electrostatic charge polarity reverse from the electrostatic charge polarity of the coating layer onto the surface of said coating layer. CONSTITUTION:The intermediate coating layer is formed on the carrier core particle by coating the particles with the resin. The fine inorg. particles treated with the coupling agent having the electrostatic charge polarity reverse from the electrostatic charge polarity of the coating layer are fixed onto the surface of the carrier having the resultant intermediate coating layer. The carrier obtd. in such a manner has the high electric resistance and adequate electrical conductivity and, therefore, the rise of the electrostatic charge quantity if fast and the carrier has the stable triboelectrostatic chargeability. The accumulation of electric charge is, therefore, not generated even if the carrier is used for a long period of time. The stable electrostatic charge quantity is thus imparted to a toner.

Filed: 1994-07-18
Abstract: PURPOSE:To reduce an unpleasant sense of a reproduced voice by preventing missing of a voice frame due to noise/voice detection error and executing voice detection processing without giving an unpleasant sense to a recipient. CONSTITUTION:A VAD threshold level 1, that is, a voice detection threshold level 1 is equal to a prediction coefficient threshold level used to decide a noise region by a noise region decision device, and a VAD threshold level 2 and a VAD threshold level 3 are used to extract a region of higher frequency of occurrence than that of the VAD threshold level 1. Thus, they are set to decide a narrower region to be a noise (silence section). A voice/silence deciding device 35 sets a voice detection flag (u) to silence L when a mean value of prediction coefficients a1, a2 enters a specific range set by any of the VAD threshold levels 1, 2, 3 selected by a threshold level changeover device 41 among plural predetermined ranges and sets the flag to a voiced sound H in other cases.

Title: Pump two-stage flow rate control method
Inventor: SUZUKI SHINJI
IPC: F04D15/00
Filed: 1994-08-09
Abstract: PURPOSE:To perform continuous operation by a method wherein when the number of revolutions of a pump is controlled to two stages of the one being a high speed and the other being a low speed and the width of a water level in a suction water tank is controlled to a constant value, the number of revolutions of a pump is reduced to the low number of revolutions so as to prevent lowering of a control level to a value lower than a lowermost value and the number of revolutions of a pump is increased to a maximum value to prevent raising of a control water level to a value higher than a maximum value. CONSTITUTION:When a suction water level is at a highest control water level HWL, a pump 2 is started at the rated number of revolutions and when a current inflow amount is lower than a delivery amount of the pump, a water level in a suction water tank 1 is lowered, whereby the number of revolutions of the pump is decreased and a delivery amount is reduced. Further, when there is a tendency for a suction water level in the suction tank 1 to lower, the number of revolutions of the pump is decreased until a suction level is reduced to a lowermost control water level LWL and the pump is brought into shut-off operation. Meanwhile, when an inflow amount to the suction water tank 1 is increased and a water level is raised as a result of an inflow amount exceeding a pump delivery amount, limitation is effected so that a water level is prevented from raising to a value higher than a maximum control water level in a way that the number of revolutions of a pump is increased and a pump delivery amount is increased.
