Title: Charging and discharging circuit for capacitor for window heater
Inventor: UKITA SUSUMU
IPC: H05B3/00
Filed: 1992-03-03
Abstract: PURPOSE:To prevent the generation of dielectric breakdown upon charging again in a plurality of capacitors, employed for the power supply of a window heater and connected in series, due to the variability in terminal voltages of individual capacitors, which are generated by natural discharge. CONSTITUTION:A first timer 21, a glass temperature sensor 43, a second timer 48 and the like detect that a predetermined period of time has elapsed after starting a vehicle, the temperature of a window glass, provided with a window heater, has exceeded a predetermined temperature and a predetermined period of time has elapsed after starting the use of the window heater, then, it is judged employing the detected factors as deciding factors whether the window heater is used or not from now on. When the window heater is judged that it will not be used, a capacitor 13 for the window heater is discharged immediately to shorten a time wherein the capacitor 13 is kept in charged condition. According to this method, the variability in the terminal voltages of respective capacitors 13 due to natural discharge can be prevented.

Title: Ion mass analysis device
Inventor: KAWAHARA SHUICHI
IPC: H01J49/30
Filed: 1986-03-03
Abstract: PURPOSE:To make it possible to recognize the sort of ion accurately, by measuring the field current and the magnetic flux density of an electromagnet for mass analysis at a time, and deciding that the resultant magnetic flux density is within the tolerance of the estimated magnetic flux density or not related to the field current. CONSTITUTION:A detecting element 10 to detect the magnetic flux is arranged in the magnetic field of an electromagnet 2. The data of the magnetic flux density detected by the system is delivered to a mass controller 9 through telemeters 7 and 8. When some sort of ion is to be mass-analyzed, it is assumed that the magnetic flux density B is necessary to be between B1 and B2 to the ion pickup voltage at the time. On the other hand, since the magnetized field H is shown as a function of the field current i, the said magnetic flux density B is also shown as the function of the field current, B=f(i). Therefore, when the lowermost coefficient is taken alpha and the uppermost coefficient is taken beta, the relation is shown as the formula I. Consequently, when the measured magnetic flux density B satisfies the formula II, the selected ion sort can be recognized accurately.
