Title: Electrostatic chuck
Inventor: SOTOZONO MAKOTO
IPC: H01L21/683
Filed: 1985-08-30
Abstract: PURPOSE:To detect an abnormal state such as dropping or unclamping, etc., of a chucked work as well as to make reliability in a chuck improvable, by installing a device detecting such voltage to be impressed on an electrode, and also detecting a setting state of the chucked work from the voltage value. CONSTITUTION:In the state that a power circuit 8 is connected to an electrode 3, voltage comes low when a chucked work 5 is not yet attracted as compared with a time when this chucked work is attracted to the electrode 3. It means that when the chucked work 5 comes off the electrode 3, a current flows between the electrode 3 and a vessel 1. Especially, when such one being once attracted drops down as a hole is opened in a dielectric thin film 2, a sudden variation in voltage occurs. This phenomenon is outputted as an abnormal signal by a comparator circuit comparing a detection voltage of a voltmeter with a reference voltage. When a switch 9 is turned on and the DC high tension power circuit 8 is connected to the electrode 3, owing to the static electricity generated by this connection, the chucked work 5 is attracted to a lower surface of the electrode 3.

Title: Image forming device
Inventor: OHASHI TSUTOMU
IPC: G03G15/10
Filed: 1989-07-25
Abstract: PURPOSE:To form an image at high speed by supporting toner tanks by a moving means in a swingable state even on the upstream side of the position of the center of gravity. CONSTITUTION:The toner tanks 3Y, 3M, and 3C (3) are supported by the moving means 5 in the swingable state on the upstream side of the position of the center of gravity. Then a specific toner tank moves to a development position in each developing process of each decomposed color. Its movement and retraction are carried out fast by the moving means 5, but the toner tank 3 slants at sudden acceleration and sudden stopping because of a force generated by the acceleration, so a little toner falls from the tank. Further, the toner tank 3 slants similarly at the time of swing-back operation in the stop state, so almost none of the toner in the tank falls. Consequently, the toner tanks can be carried fast without the falling of the liquid toner, the time required for the toner tank conveyance is shortened greatly, and the fast image formation becomes possible.

Abstract: PURPOSE:To obtain an accurate flow rate by providing a detecting means for operating a decreasing rate of a flow rate based on a pulse period and detecting a specified value of the decreasing rate, a pressure detecting means, a correcting-value generating means and an integrating means. CONSTITUTION:A over-meter-start detecting circuit 18 and a over-meter-end detecting circuit 19 measure the period of a pulse. The over-meter-start detecting circuit 18 generates an over-meter-start signal OMS when the difference in number of rotation is a specified value DELTAN or more and supplies the signal into a correction operating circuit 15 and an over-meter-elapse-time measuring circuit 20. The over-meter-end detecting circuit 19 generates a signal OME when the difference is less than DELTAN or zero or less. The over-meter-elapse-time measuring circuit 20 measures the elapsed time and outputs the time into the correction operating circuit 15. An integrating circuit 16 integrates the pulses from an amplifier 14 and stops the device during the period from the signal OMS to the signal OME. The operating circuit 15 correct the insufficient integration of the flow rate.

Abstract: PURPOSE:To surely prevent the generation of white smoke in a cooling tower by heating the air stream by introducing a portion of the hot water which is obtained by separating steam from the geothermal heat fluid and mixing said heated air stream into the liberated air in the cooling tower. CONSTITUTION:The geothermal heat fluid 1 is separated into steam 3 and hot water 4. The steam 3 which generates electric power by revolving a turbine 5 is changed to the warm water by the cooling water 7 and introduced into a cooling tower 8. In the cooling water 8, the warm water is dispersed as shower 17, and changed to the cooling water 7 having a temperature of 30 deg.C or less through the contact of the cooling air 11, and allowed to circulate into a condenser 6 again. While the air stream which contains a large quantity of steam through the contact with the warm water 17 is liberated into the atmosphere from the upper part of the cooling tower 8, and the following processing is carried out at this time. In other words, a portion of the hot water 4 is introduced into a heat exchanger 15 and used for heating the supplied diffused air 15, and the heated air 16 is added into the liberated air stream. Therefore, the steam pressure in the liberated air is considerably reduced in comparison with the saturated steam pressure, and the generation of the white smoke due to the cooling in the atmosphere is prevented, and the generation of the public nuisance is avoided.
