Title: Variable capacity circuit
Inventor: SAKURAI YASUHIRO
IPC: H01L27/04
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To increase the changing rate of the capacity of a MOS capacitor in the extent of a working voltage by a method wherein the gate electrode of the MOS capacitor connected with a first fixed capacitor uses a first control signal as the input and the opposed electrode to the electrode of the MOS capacitor connected with a second fixed capacitor uses a second control signal as the input. SOLUTION: First and second control signals A and B for deciding the capacitance of a MOS capacitor 3 are respectively intercepted by first and second fixed capacitors 1 and 5 from their peripheries in a DC manner. For that, an arbitrary potential can be set in the capacitor 3 in the extent of a power supply voltage. There, if the signal B, for example, is substantially held to the degree of half of the power supply voltage and the signal A is changed from a ground level to the power supply voltage, a C-V curve is equivalently used in the range from a negative region to a positive region of a gate voltage. As a result, the widest extent of a change in the capacity of the capacitor 3 results in being able to be used and the changing rate of the capacity is significantly enhanced.

Title: Quantitative liquid delivering device
Inventor: NAGAOKA TETSUO
IPC: F04B9/12
Filed: 1983-09-14
Abstract: PURPOSE:To permit the stable delivery of liquid of a constant quantity by a method wherein the reciprocating motion of an air cylinder is transmitted to a bellows directly to pump the liquid by a pressure difference due to the elongation of the bellows and eliminate generation of abrasoin under putting the liquid contacting with the surface of the device into non-sliding condition. CONSTITUTION:When compressed air from a compressed air flow path 2 is stopped and a two-way valve provided on an compressed air introducing pipe is opened, a piston rod 5 retreats by gravity and the bellows 11 is elongated. At this time, a vacuum is generated, therefore, a check valve CV1 is closed, the check valve CV2 is opened, the pressure difference of the bellows 11 is transmitted to the flow path 4 bored on the piston rod 5, the check valve CV3 is opened and the liquid is sucked. By repeating such actions, a main body 27 is filled with the liquid. When the valve 28 is opened here, the liquid passes through the flow path 29, opens the check valve CV4 and is discharged out of a delivery port for a liquid reserving chamber 33. In this case, the volume of the bellows 11 pushed by the piston rod 5 is constant, therefore, the pressure thereof is also constant. Accordingly, stabilized suction and delivery of the liquid of a constant quantity may be effected under putting the liquid contacting with the surface of the device into non-sliding condition at all times.

And when the work is put in a put-in stocker 10 with a traversing truck in the working order, an identifying head 24 of an identifying device 16 is pressed against the work by the operation of a cylinder to identify the type of the work and check the content according to the put-in indicating data and work memory. When the content coincides with said data and memory, the work begins to be worked in a working position 14B. On the other hand, when such coincidence is not found, the work is returned to the keeping stocker. Thus, accurate working direction is given to the working machine so that defective working can be prevented while many types of works can be worked unmanned.

Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To determine the judging area easily and objectively without requiring any skill by comparing the distribution data between normal and abnormal groups of specimen, calculating the difference statistically and determining an abnormal particle judging area. SOLUTION: A particle judging criterion determining unit 200 receives the distribution data (distribution chart) of each scattergram of a large number of normal and abnormal specimens (appearing premature granulocyte) from a particle analyzer 100. Data preparation means 12, 13 then prepare a basic normal scattergram distribution chart and a basic abnormal scattergram distribution chart. Subsequently, an area determining means 14 removes (deletes) the basic normal scattergram from the basic abnormal scattergram to produce a single typical area which is then set, as an abnormal particle judging area, in a signal analyzing means 7. Upon emergence of a detected cell (premature granulocyte) in the area W, the analyzing means 7 counts the number of emergence and when the count exceeds a predetermined value, a message corresponding to the emergence of abnormal cell is displayed 8.

Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To recognize a contaminated, rusted or deformed coin, as well as a true coin, by determining an optimal threshold value for binarization from an image data being read out depending on the surface conditions, e.g. contamination, rust or deformation. SOLUTION: When a coin 1 is thrown in, a light source 4 is lighted and a reflected light from a half mirror 6 is further reflected on the coin surface to enter into a reading section 7. A coin type decision section 9 decides the coin type through comparison with a reference outside diameter data. A binarization section 10 binarizes the image of the coin 1. An appropriate threshold value is set such that the fluctuation of output due to contamination, rust and deformation of the coin 1 has no effect. A data binarized based on the threshold value is outputted to a reference data extracting section 11. A true/ false decision section 12 takes out a relevant reference image from several reference images prestored in a registration pattern storing section 13 and makes a comparison.  In addition to the decision of the true coin and the type thereof, a decision is made depending on the surface conditions, e.g. contamination, rust or deformation of the coin.

Abstract: PURPOSE:To efficiently and smoothly carry toner with simple constitution by using a coil spring as a toner carrying means. CONSTITUTION:The endless coil spring 510 is arranged to be able to circulate between a cleaning device 400 and a developing device 300. Since the coil spring 510 is driven to circulate by a driving gear 520, excess toner which is not submitted for development in the toner storage chamber of the developing device 300 is carried to the cleaning device 400, stirred and mixed with the recovered residual toner in the cleaning device 400, and restored to the developing device 300 again. Since the upper end of the coil spring 510 is positioned upper than a sliding part between a developing roller 320 and a regulating blade 330, toner clogging occurring at the exit of the toner storage chamber because overflowing toner gets on the coil spring 510 and is carried excessively, is prevented.

Abstract: PURPOSE:To shorten the time required for titration, setting the injection of a titration liquid as calculated by the specified formula to minimize the excess at the final point. CONSTITUTION:Chemical change of a titration liquid in a titration tank is detected as electrical signal each time the titration liquid is injected into the tank. The subsequent injection X of the titration liquid is calculated by the formula from rates of change DELTAPH1 and DELTAPH2 obtained by respective amounts of change in electric signals before and after the injection, preceding and the last but one, of the titration liquid by the values corresponding to the respective amounts of injection thereof, the value PHE corresponding to the PH at the final point and the value PHN corresponding to the current PH. As the subsequent amount of titration can be calculated using the rate of change theta in DELTAPH1 based on the DELTAPH2 obtained at the time last but one as variable, the forecast line B can be approximate to the variation curve of PH. In the titration of this invention, a sample solution having a buffer capacity can be titrated causing no excess at the final point without no time lag in the measuring speed regardless of variations in the buffer capacity.
