Title: Method for forming free curved surface
Inventor: KURAGANO TETSUZO
IPC: G05B19/4097
Filed: 1986-03-20
Abstract: PURPOSE:To form a patch having a smooth free curved surface in a framing space by applying the partial differentiation to a vector function showing the patch to obtain a conditional formula which decides the internal control points. CONSTITUTION:Many framing spaces enclosed by boundary curves BOD1-BOD4 are formed by the framing process. Then a patch S(u,v) expressed by a vector function having parameters (u) and (v) showing positions is stretched in those framing spaces. Thus a free curved surface is produced. In such a forming method for free curved surface, the partial differentiation is applied to the vector function showing the patch S(u,v) with parameters (u) and (v). Thus a conditional formula having reduction of the number of degrees is obtained. Based on this conditional formula, the control internal points P(11), P(21), P(22) and P(12) are decided to prescribe the patch S(u,v). The patch obtained in such a way has a smooth form since the number of orders are reduced by the partial differentiation.

Filed: 1988-03-17
Abstract: PURPOSE:To detect the pressure difference and to allow more proper control of the motor fan by locating a pressure sensor in a cell formed from a pressure bulkhead having a pressure tube fitting part and a substrate. CONSTITUTION:A pressure pipe fitting part 43 of a pressure sensor 42 is projected through a through hole 49 formed to a substrate 40 to the back surface side of the substrate 40. Further, in the circumference of the pressure sensor 42 on the surface of the substrate 40, a pressure bulkhead 51 in a box shape is fixed so as to cover the pressure sensor 42. A cell 53 to be surrounded by the pressure bulkhead 51 and substrate 40 and to have the pressure 42 built in is airtightly isolated from a space part made into an atmospheric pressure in an external part. From a sensor part 41, an electric signal according to the difference in the pressures between a negative pressure space part and a dust collecting room internal part, namely, the pressure differential in the upstream side and downstream side of a dust collecting filter is outputted. For such a reason, since the pressure differential at two points in an air course can be sensed, the blockage of a dust suction port, the blinding of the dust collecting filter, etc., can be discriminated, and the motor fan can be more properly controlled.

Title: Ink jet recording device
IPC: B41J2/01
Filed: 1992-03-23
Abstract: PURPOSE:To lessen the bleeding of ink and make the same clear by making a contact angle of ink and a recording medium smaller than the contact angle regulated by the physical properties of ink and the wetting properties of the recording medium at the time when the jetted ink adheres to the recording medium. CONSTITUTION:Ink drops are deformed just after ink particles jetted by transmission come into collision with a medium, and eventually the drops are stabilized at a contact angle determined by the physical properties of ink and the wetting properties of the recording medium. When the ink particles jetted out at high speed come into collison with the medium, the deformation is large and the contact angle formed by the physical properties of ink and the wetting properties of recording medium cannot be retained, and the particles are stabilized at a small contact angle. The larger the particle speed of ink is made, the smaller the contact angle of ink particles is to make the fixing time of ink quicker. The voltage value applied to a printing drive section 21 for driving an ink jet head 20 is made variable by means of variable resistance of a control section 70a for the purpose of varying the jetting speed of ink particles from high speed to low speed. The applying voltage of the printing drive section 21 is varied by operating a switch 80a to make the speed of ink particles high.

Title: Method for renewing coefficient of adaptive filter

IPC: G10K11/178
Filed: 1994-03-09
Abstract: PURPOSE:To shorten the time required for coefficient renewal by obtaining a mutual correlation between error and reference signal in a convergence evaluation part and stopping the coefficient renewal by that a mean value becomes a minimum value. CONSTITUTION:A white noise is sent from a white noise generator 10 to a cross talk prevention filter 2 and an acoustic feedback transmission system (b), and the coefficient renewal of the cross talk prevention filter 2 is performed. At this time, the mutual correlation between an error signal obtained by an subtracter 21 and the white noise from the white noise generator 10 is calculated by a mutual correlation calculation part in the convergence evaluation part 9, and when the mutual correlation exists, the moving average value of the error signal is obtained by a moving calculation part. The moving average value is compared with the moving average value obtained beforehand, and whether or not the further lower minimum value is obtained, is investigated. As the result, when the minimum value which can not be lowered more is decided finally, a renewal stop instruction part is instructed to send a renewal stop instruction signal to the white noise generator 10 and a coefficient renewal part 11. Thus, the white noise generator 10 stops the sending of the white noise.
