Title: Oil-water separation
Inventor: KOBAYASHI ATSUSHI
IPC: B01D17/022
Filed: 1983-05-31
Abstract: PURPOSE:To separate forcibly and efficiently oil from water by covering a magnetic substance with a hydrophilic or an oilphilic substrate,putting the material into a mixed liquid of oil and water, and applying magnetic force. CONSTITUTION:A particle 4 of a magnetic substance is covered with a hydrophilic or an oilphilic substrate 5 to prepare an additive which is thrown into a mixed liquid 3 of oil and water and stirred. Since the surface of the particle 4 of a magnetic substance thrown into the mixed liquid 3 is covered with the substrate 5 which is oilphilic, for example, the substrate 5 collects and adsorbs oil particles 2 in the mixed liquid 3. Then magnetic lines of force 8 which are headed upward from the bottm of a vessel 1 are applied by flowing an electric current from an electric source 7 through a coil 6 provided on the outer circumference of the vessel 1. The particle 4 of a magnetic substance, after collecting oil particles 2 in the mixed liquid 3, is moved upward by the magnetic lines of force 8, and an oil phase 9 and a water phase 10 are separated.

Title: Substance structure analyzing device utilizing light scattering measurement
Inventor: OKA KOICHI
IPC: G01N21/21
Filed: 1994-05-09
Abstract: PURPOSE:To eliminate noise to enhance analyzing accuracy and extract information on a particle material property value to the maximum. CONSTITUTION:Two dimensional detection of a scattering intensity pattern is conducted, an azimuth mu is changed for concentric circular sampling, and a Fourier coefficient as a function of the azimuth mu is found. Since the found Fourier coefficients are equivalent to respective coefficients in a polynominal of trigonometric functions of the azimuth mu of scattering intensity obtained from a theory or integer-multiplication of the azimuth mu, and are functions of material property values such as a size, length and orientation angle of particle, simultaneous equations without including the azimuth mu can be obtained. Solution of these simultaneous equations can provide various kinds of material property values as numerical values. In comparison to a conventional method for estimating micro-structure from a pattern approximation degree and a method for finding the material property value from one dimensional measurement data, measurement with high accuracy and without influence of noise can be attained, and numerical expression of a specific material value, which is impossible by a conventional analyzing method, can be realized.

IPC: G01G11/00
Filed: 1984-05-11
Abstract: PURPOSE:To feed tea leaves constantly keeping the preset rate of flow, irrespective of the careless oscillation of the feeder, by measuring the real flow rate of the tea leaves with high accuracy, and correcting the running speed of the belt conveyor according to the measuring value. CONSTITUTION:Tea leaves are charged almost continuously to the hopper 14 of the metering conveyor 17 by driving the feeder 1, and at the same time, the conveyor 17 is driven to discharge the charged tea leaves from the end of the conveyor 17. When the weight of the whole conveyor reaches the upper limit, the motion of the feeder is stopped while continuing the motion of the conveyor until the weight of the conveyor reaches the lower limit, when the motion of the feeder is started again. During the period from the time when the weight of the whole conveyor reaches the upper limit to the time when it reaches the lower limit, the whole weight Yi (i=1-n) of the conveyor is measured at each check time Xi, and the obtained data (X1, Y1)-(Xn-Yn) are processed by the method of least squares. The constants A and B are calculated to approximate the trend of weight decrease by the formula Y=AX+B, and the value A is used as the flow rate of the tea leaves per unit time in the above period.

Title: Printing device
Inventor: TERASAWA HIROHARU
IPC: B41J2/185
Filed: 1983-06-01
Abstract: PURPOSE:To detect a residual quantity of ink in an ink tank, by providing a pressure detecting means between the ink tank and a printing head, and by detecting the pressure of ink thereby in linkage to the suction of ink. CONSTITUTION:The discharge port of an ink jet head 7 is closed tightly with a capping 8 by a driving means, and a suction device 10 is driven through the intermediary of a switch 11. Then, a delay is made for a prescribed time by a delay circuit 14, and the pressure inside an ink supply channel 5 is detected by a pressure detector 4. The pressure inside the ink supply channel 5 which is in a high negative pressure region immediately after the operation of the suction device 10 recovers gradually to that in a region in which it is close to the atmospheric pressure, in the course of time corresponding to a channel resistance. When there is sufficient ink in an ink tank 1, the pressure returns to that higher than a certain empty level. When the residual quantity of ink decreases, the recovery of the pressure requires an increasing time, and when the residual quantity thereof decreases to nearly zero, the pressure falls below the prescribed empty level.

Title: Mobile object, mobile object position registration device and mobile object communication system
Inventor: MORI TAKUYA
IPC: H04W64/00
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a mobile station by outputting a position registration message with a period which is based on the detected moving speed of an automatic mobile object. SOLUTION: Base stations A and B which received position registration messages based on the turn-on of power in as mobile station register the present position of the mobile station, selects a position registration period and transmits it to the mobile station. When a position registration timer counting the position registration period is terminated, the mobile station receiving it transmits the position registration message to the base stations A and B. The base stations A and B select the position registration periods again, and they are transmitted to the mobile station with a position information. Here, the mobile station calculates a moving distance and a moving speed from the position information which are received this time and previous time and they are stored in a RAM 17.  A control part 16 reads a discriminating value showing the relation between the moving speed and the registration period from a ROM 18 and compares the moving speed with a threshold. Then, the change request of the position registration period is transmitted to the base stations A and B if necessary, and the position registration period is changed.

Title: Paper traveling mechanism for electrophotographic system printer
Inventor: ASADA HIDEKAZU
IPC: G03G15/00
Filed: 1988-04-18
Abstract: PURPOSE:To stabilize paper's traveling by equipping a drum case provided with a pressure spring which raises a paper traveling guide toward a photosensitive drum and a stopper part which presses down the end part of the paper traveling guide. CONSTITUTION:The pressure spring 2 always works to raise the paper traveling guide 3 in the direction of an arrow and a limit bracket 4 becomes a stopper in a state where the drum case 5 is not inserted. When the drum case 5 is inserted into a main body, the stopper part 6 of the drum case 5 presses down the paper traveling guide 3, which is rotated to be moved with the aid of a rotation part 7 on the end of the paper traveling guide 3. By controlling only the position of the photosensitive drum 8 inside the drum case 5 and the position of the stopper 6, a gap between the photosensitive drum 8 and the paper traveling mechanism part can be kept constant without adjustment. Thus, the paper can be made to stably travel.
