Title: Method for measuring heat generation of liquid utilizing heat conductivity and calorimeter used therein
Inventor: DOI TOSHIYUKI
IPC: G01N25/20
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To calculate the heat generation of liquefied gas regardless of liquid density by calculating the temp. gradient of a liquid from the heat conductivity thereof at two different temps. SOLUTION: A thermometric resistor(TCD) dipped in liquefied gas to be measured is controlled in current so that the temp. thereof becomes constant and holds heat generating temps. TRh1, Thh2 when the value of a variable resistor Rc is Rc1, Rc2. At a time of measurement, the liquefied gas takes heat proportional to the heat conductivity λ thereof from the TCD 1 and, since powers necessary for setting the heat generating temps. of the TCD to TRh1, TRh2 are different, a current flowing to a resistance value Rh and voltages at both terminals change.  At this time, the voltage generated at the connection point with a resistor R1 is inputted to a comparator 3 as output voltages V1 (at a time of a variable resistance value Rc1), V2 (at a time of a variable resistance value Rc2) and the change of the heat conductivities λ at two different temps. of the TCD 1 is detected as the change ΔV of output voltage. A heat conductivity temp. gradient calculating part 4 calculates the heat conductivities λ1, λ2 of the liquefied gas at two different temps. and the temp. gradient α thereof from the change of applied voltage V and heat generation calculation part 5 used them to calculate heat generation.

Abstract: PURPOSE:To carry out excellent image recording regardless of the state of a recording sheet and simultaneously to prevent the malfunction of a controller caused by discharging by setting the volume resistivity of a bearing supporting a resist roller mode of metal to a specified range. CONSTITUTION:The skew of the recording sheet is corrected by the resist metal lic roller 8 and a resist rubber roller 9. Then the sheet is guided between a photosensitive drum 1 and a transfer device 2.

When the volume resistivi ty is <=10<6>OMEGA.cm and the recording sheet is in a humidity conditioning state, a charge on the recording sheet is discharged from the roller 8 and the bearing 14, and the failure of a transfer having the void of an image occurs. On the other hand, when the volume resistivity is > 10<10>OMEGA.cm, the charge generated by the friction of the recording sheet and the roller 8 can not be discharged from the roller 8 and the bearing 14 so that the discharging from the roller 8 toward a device main body 13 occurs and the malfunction of the controller occurs, as well.
