Title: Method and apparatus for continuous separation of charged high molecular compound
Inventor: MORUDECHIYAI PERII
IPC: C07K1/26
Filed: 1989-11-14
Abstract: PURPOSE: To prevent the decrease in the separating efficiency of polymer compound due to the leakage of acid and base by providing a membrane compartment chamber having a supply cell and a permeable cell divided by a permeable microfiltration membrane or ultrafiltration membrane to polymer compound. CONSTITUTION: Supply solution 10 is sucked by a pump 17 by pressurizing of pressure drive diaphragm process to flow along the high pressure side supply cell 2 of a microporous membrane 1 in its tangential direction. On the other hand, an electric field is applied perpendicularly to the membrane 1 via an anode 4 and a cathode 5. A supply circulation flow parallel with the membrane 1 is held so that no gel polar substance exists in the membrane 1, and makes it possible to maintain permeable flux. When permissible material permeates the membrane 1, only the component which is not charged or has electrophoretic speed of the same direction as the flux can completely move to the permeated side cell 3. Then, the permeated material can flow out from the cell by the flow generated by the applied pressure.  The flowing velocity of the material can be regulated to a predetermined value by the pressure.

Title: Fail-safe system for direct-acting valve type automatic transmission
Inventor: WAKAHARA TATSUO
IPC: F16H59/68
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent errors in the detection of a failed condition resulting from delay in relieving of operating hydraulic pressure which occurs within a predetermined time from a transient shift state and a steady state, for a direct-acting valve type automatic transmission which directly controls the operating hydraulic pressures of a plurality of friction elements by means of individual direct-acting valves when the plurality of friction elements are selectively engaged to make shifts. SOLUTION: When a switching shift is made by supplying actual engagement pressure P1 as the operating hydraulic pressure PA of the friction element A and supplying actual disengagement pressure P2 as the operating hydraulic pressure PB of the friction element B, a fail-safe system determines whether or not an interlocked state occurs, according to the relationship between the actual engagement pressure P1, the actual disengagement pressure P2 and a set pressure Psw after a predetermined time Δt has elapsed since the steady state C0 (failure sensing logic operating region Fs). Thus, the fail-safe system does not determine whether or not the interlocked state occurs, in a region ΔFm wherein errors may occur in determination as to whether or not the interlocked state occurs.

Title: Automatically manageable locker apparatus for baggage or the like
Inventor: KAWASAKI TETSURO
IPC: A47G29/122
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To allow even a thin baggage to intercept a light beam of a light sensor by forming a protrusion near the center of a bottom plate extending in the linear direction at a specified angle to the direction of light runs of the light sensor and with the tip thereof not flat so as not to injecept the running light. SOLUTION: A protrusion 10 is formed extending in the linear direction at an angle of 45 deg.-135 deg. to the direction of the light 20 passes of a light sensor at the center of a bottom plate 6. In design, the height of the protrusion 10 is so set as not to intercept the passing light beam 20 of the light sensor and with an inverted V shaped cross section, the protrusion 10 extends continuously in the linear direction. When a letter 30 is placed in a locker box, with the tip of the protrusion 10 not flat, the letter 30 is not kept horizontal and is tilted to the right or left so that the bottom side of the letter 30 can be maintained at an inclined attitude contacting the bottom plate 6 thereof. As the letter 30 is at the inclined attitude, a part near the top side of the letter 30 intercepts the light beam 20 of the sensor accurately.  This allows the housing of even a thin baggage or the like in the apparatus with the protrusion 10 at the inclined attitude thereby detecting it accurately with the light sensor.

The fact that the measured value of the scale 3 agrees with the detected value before the determination which is smaller than the desired value by the correcting value for the head is detected, and the discharging port of the device 4 is closed. Then, after the time required for loading the scale 3 with the raw material 6 which is floating in the head between the device 4 and the scale 3, the final measured value of the scale 3 is read out. Then, the discharging port of the scale is opened, and the raw material 6 is discharged. Thereafter, a cummulatively added value A of the deviations between the final measured values and the desired values is computed. The average value of the amounts of the errors is computed every time based on the number of measuring cycles N and the added value A. In a control part 10, the head correcting value of the next measurement is corrected with the newest average value of the amounts of the errors.
