Title: Temperature detecting circuit
Inventor: NARITA YOSHIAKI
IPC: G01K7/00
Filed: 1987-04-30
Abstract: PURPOSE:To obtain a detecting circuit capable of being constructed by low- priced parts and resistant to an external noise by using diodes and a subtracter. CONSTITUTION:Diodes D1 and D2 have the same temperature characteristics and are accommodated in the same package 5 to form a temperature sensor 4. When the forward voltage of the diode D1 is VF, -KXVF (K is a proportional constant) is outputted from a differential amplifier 1 and, similarly, +KXVF is outputted from a differential amplifier 2. Thus, +2KXVF is outputted from a differential amplifier 3. Since a lead wire connecting the sensor 4 and a circuit to each other passes the same location, noises inputted to a subtracter 21 (composed of the amplifier 1 and resistors R11-R14) and another subtracter 22 (composed of the amplifier 2 and resistors R21-R24) have the same direction and the same quantity. Further, since the noises in the circuit are the same as above by using the same ICs, even when a deviation with the same quantity and the same direction is generated in an output to a subtracter 23 (composed of the amplifier 3 and resistors R31-R34), a stable voltage proportional to both end voltages of the diodes D1 and D2 can be obtained as the output of the subtracter 23.

Abstract: PURPOSE:To prevent the breakdown of a convergent optical transmitter and the overheating of an original platen, by providing the 1st duct for discharging the ambient air around the convergent optical transmitter and the 2nd duct for discharging the ambient air around a fixation device. CONSTITUTION:The ambient space is heated up by the heat radiation from an exposure device 19 and the fixation device 9, but the air sent suctionally into the 1st duct from an air intake 22 by a fan 21 passes by the exposure device 19, cools a reflector 16, light source 17, and convergent optical transmitter 18, and is then discharged from an air outlet 23. The fixation device 9 is cooled indirectly by the discharge flow from the fan 21 and the air from the side of a paper feed cassette 7 is guided by the 2nd duct 25 and mixed with the discharge flow from the fan 21 to be discharged from a main frame 1.

Abstract: PROBLEM TO BE SOLVED: To efficiently read out the resistance change of a magnetic resistance effect element by constituting magnetic shielding layers holding the magnetic resistance effect element there between with conductive materials and connecting magnetic shielding electrodes to respective magnetic shielding layers. SOLUTION: The electrode part of one side of a magnetic resistance effect element 1 is connected to a lower magnetic shielding layer 2 at a contact part 1A and a lower magnetic shielding electrode 8 is fitted to the lower magnetic shielding later 2.

Title: Digital/analog converting circuit
Inventor: MIYAKE MASAYASU
IPC: H03M1/08
Filed: 1987-05-01
Abstract: PURPOSE:To simplify a filter for noise rejection by adding a circuit applying pre- processing before the DA conversion, and adding an integration circuit and an accumulative adder circuit after the stage of the DA conversion, in place of an LPF succeeding to a DA converter in a conventional circuit to reduce loopback noise. CONSTITUTION:A signal A is supplied to each input of a pre-processing circuit comprising a subtraction circuit 2 and a delay element T of one sampling period and an output signal C is obtained. The signal C is converted into an analog signal D by a DA conversion circuit 3 and signal D is integrated by an integration circuit 4. A switch S1 discharges an electric charge of the capacitor C1 when the integration device integrates the output D of the DA converter of one sampling in a way that the switch discharges the electric charge in a capacitor C1, thereby allowing the integration device to always start the integration from zero. The control is attained by using a pulse train H. The integration output E is added to a sampling signal G of the integration value being the result of addition for one period till the peceding sampling point by an adder 5 and goes to an output being the result of linear interpolation of an output signal F line. The spectrum of the signal F is reduced. Thus, the slow characteristic of the filter LPF 9 is enough for the application and a simple filter with a few components may be employed.

Abstract: PROBLEM TO BE SOLVED: To shorten handoff connection time by directly starting a communication state with a communication channel(ch) when a mobile station moves into another base station zone. SOLUTION: Concerning a handoff control system for a system having call re-originating type handoff in single communication in communication for moving object, a base station 1 assigns the radio condition of a communication ch f34 assigned in a radio communication zone 42 of a base station 2 to a channel designation message reported by a control ch f31 and transmits this channel designation message to a mobile station 11 in a radio communication zone 41 of the base station 1.
