Title: Method for removing malodor
Inventor: MIKAMI YASUYA
IPC: B01D53/77
Filed: 1987-06-17
Abstract: PURPOSE:To remove effectively sulfur containing malodor components by bringing such components into contact with a solution of iron salt mainly composed of ferric iron and whose pH is below 4, separating a precipitated product and recovering ferrous iron from the separated liquid. CONSTITUTION:An iron salt solution, whose main constituent is such a ferric iron salt as ferric polysulfate, ferric sulfate, ferric chloride or ferric nitrate etc., and whose pH is below 4, is prepared. This iron salt solution is brought into contact with a sulfur containing malodor component and a precipitated product mainly composed of sulfur is separated from that iron salt solution. Then ferrous iron in the separated liquid is oxidized to ferric state and repeatedly utilized. The said malodor component means hydrogen sulfide, methyl mercaptan or methyl sulfide etc. By adopting this method, the iron salt solution for absorbing the malodor component can be repeatedly utilized, and furthermore an occurrence of secondary pollution can be avoided.

Title: Planetary gear type reduction gear
Inventor: KATA KATSUKUNI
IPC: F16H1/28
Filed: 1988-06-17
Abstract: PURPOSE:To prevent the seizure between a ring gear and a pad and prevent the change in a slip torque value caused by temperature change by forming at least one of the pad and an elastic member forming a friction type torque slip mechanism provided on the outer periphery side of a ring gear with a shape memory alloy. CONSTITUTION:If a rotary shaft 4 is fixed because of the failure of a motor, an output shaft 5 side tends to rotate by inertia causing a large load to act on a reduction mechanism 2. As this load gets above a torque slip value of a friction type torque slip mechanism 105, an A-line side ring gear 102 is rotated against the energizing force of the mechanism 105. When temperature rises to above a defined temperature, the shape of a pad 107 which is formed with a shape memory alloy is changed into an arc shape, thereby increasing the sliding contact area between the pad 107 and the ring gear 102. Thereby, the lowering of the frictional force between the pad 107 and ring gear 102 can be compensated, accordingly, preventing inadvertent rotation of the ring gear 102.

If a busy subject is identical with the subject of the transfer destination, the transfer of the signal to be carried out by the means 15 is held by a holding means 15. Then the means 15 transfers the received picture after a call is finished. Furthermore an instruction means 17 outputs the answer instructions of the transfer destinations based on the priority and in accordance with those transfer destinations stored in a storage means 17. Then the means 15 transmits the signal of the received picture. Thus the reception of the FAX 10 can be directly transferred again to a proper deputy through an extension.

Title: Power unit for wide temperature range operation system
Inventor: MURAKAMI SATOSHI
IPC: G06F1/00
Filed: 1992-05-19
Abstract: PURPOSE:To allow a CMOS type IC to execute a stable operation without being affected by temperature by including a means for generating power supply voltage capable of setting up the operation speed of a CMOS type IC to a specific value at a temperature obtained by a detecting means. CONSTITUTION:When the information of a peripheral temperature sensed by a temperature sensor 1 is transmitted to a power supply voltage controller 2, the control information of voltage corresponding to the temperature is transmitted to a power transistor(TR) 3, which generates a proper voltage and sends the voltage to a CMOS electronic circuit 4. The information from the TR 3 is fed back to the device 2 again to monitor the level of the voltage. At this time, when the sensor 1 obtains low temperature information, the device 2 requests a low voltage to the TR 3 in order to reduce the speed of the CMOS, and at the time of obtaining high temperature information on the contrary, the device 2 requests a high voltage to the TR 3 to increase the operation speed of the CMOS. Thus the operation speed of the circuit 4 can be always held at a prescribed value.

Namely, in the case output from a toner density sensor 28a becomes lower than a toner density center value, the printer CPU54 lowers and controls the output from an electrifying device 24 in accordance with the lowering of the output from the sensor 28a, so that the surface potential of the drum 22 is lowered and controlled. Thus, the faulty image caused by the carrier attraction is prevented.
