IPC: G06T7/00
Filed: 1988-08-29
Abstract: PURPOSE:To avoid convergence to a local minimum and to set each parameter to a true optimum value by correcting the size of the inclination of the respective parameters in an evaluation function in correspondence to an importance degree to the specification of a shape. CONSTITUTION:When observing data are inputted, at first, an (i) which shows gradually changing stage is caused to be (i)=1 and an initial value X1 of a parameter group X1 is set. Next, gradient  f(X1) of the evaluation function is obtained from the initial value X1 and inputted observing data. On the basis of an expression I [Xi+1=Xi-C. f(Xi)], a parameter group X2 of the next gradually changing stage is obtained. On the basis of an expression II (¦Xi+1-Xi¦<kappa), ¦X2-X1¦ is obtained and size comparison is executed between this ¦X2-X1¦ and the kappa. When the ¦X2-X1¦<kappa is not satisfied, processing is executed in a stage that the evaluation function is not converged to an extremum. When the ¦Xi+1-Xi¦<kappa is satisfied, the Xi+1 at such a time is deter mined as a parameter group P to give the extreme value of the evaluation function f(X1). This determined parameter group P goes to be an identification parameter and determines a stereoscopic shape function.

Abstract: PROBLEM TO BE SOLVED: To perform viscosity adjustment for fluid such as ink accurately, by providing a control unit which outputs signals which open a valve for supplying a diluent for a preset time when required viscosity deviates from a predetermined range of viscosity. SOLUTION: Ink within an ink tank is sucked by a diaphragm pump 10 of a viscosity adjusting unit 1, and the number of pulsations during a unit time is detected by a pressure switch 32. The result of detection is inputted to a CPU 30, and viscosity is calculated by a relational expression based on the result of preliminary experiments. The control limit (upper limit) of viscosity is set by a viscosity range definer 34, if measured viscosity exceeds the range, an electromagnetic valve 25 opens for a preset time. Thus a solvent within a solvent tank 20 is added to ink and dilutes the concentration of the ink and lowers its viscosity. During this solvent addition, it is signaled by a buzzer 40.

Filed: 1983-11-11
Abstract: PURPOSE:To transmit power by a mechanism reducing its noise and eliminating any backlash, by bringing both members, consisting of magnetic material, into rolling contact with each other by magnetic attractive force. CONSTITUTION:One member 1, consisting of magnetic material, arranges the other member 5 so as to come into rolling contact with it, and the member 5 is constituted by disk members 2, 3 and a magnetic force generating means 4 concentrically and integrally built between these members 2, 3. In accordance with the polarity of this means 4, magnetic flux is formed in a direction of the members 2, 1, 3 in that order or in a direction opposite to the direction in said order. Accordingly, magnetic attractive force, being generated mutually between the both members 1, 5, enables power to be smoothly transmitted continually under a rolling contact condition by actuating one of the members as a driving side and the other member as a driven side. As a result, the power is transmitted by a mechanism reducing its noise also having a torque limiter function without causing also the backlash.

IPC: F28D11/02
Filed: 1988-08-26
Abstract: PURPOSE:To eliminate the adhesion of scam and the like on the outside surface of a disc and keep a high heat exchanging efficiency for a long period of time by a method wherein a bulkhead, partitioning the inside of a hollow drum into an operating liquid inflow passage and an operating liquid outflow passage, is provided and a scraper is arranged at the proximity of the outside surface of the hollow disc. CONSTITUTION:Since the density of the operating fluid of gas is smaller compared with the density of the operating fluid of liquid while a hollow disc 5 is rotated, the operating fluid of gas is replaced by a centrifugal force with the operating fluid of liquid having a larger density, the operating fluid of liquid is contacted with the inner wall of the hollow disc 5 at all times and, as a result, heat conduction between the inner wall surface of the hollow disc 5 and the operating fluid is increased. On the other hand, the operating fluid of gas is collected in the central part 14 of the hollow disc 5 and the gas is separated from the liquid whereby the operating fluid of gas is discharged to the outside of a rotary disc type evaporator A through an operating fluid outflow passage 9 and an outflow pipe 7. Even when adhesive scam is mixed in a heat source fluid, the outer wall surface of the hollow disc 5 is cleaned by a scraper 11 at all times and, therefore, the deterioration of the heat conduction between the heat source fluid and the outer wall surface of the hollow disc 5 due to the adhesion of the scam may be prevented.
