Inventor: FURANKU BUEE FUARUKENBERUKU
IPC: C12M3/00
Filed: 1993-09-01
Abstract: PURPOSE: To obtain the subject culture vessel capable of generating cell culture with a high cell density and readily handling and reduced in the danger of infections by providing a gas exchange membrane which at least partly delimits the cell culture chamber as feeding and discharging system of gas.  
     CONSTITUTION: A cell culture chamber 5 and a nutrient supply chamber 6 are separated by a dialysis membrane 9 and a nutrient and a metabolism product are transported through the dialysis membrane 9. The cell culture chamber is partly delimited by a gas exchange membrane 12 which does not permeate microorganism and liquid which pollute cell culture products. Thereby, feed and discharge of the gas is carried out and oxygen is sufficiently supplied to the cell so as not to restrict growth of cell.

Title: Expansion antenna
Inventor: FURUKAWA KOICHI
IPC: H01Q15/20
Filed: 1988-08-31
Abstract: PURPOSE:To constitute a large sized expansion antenna with a higher height by forming at least one of folded parts with split lines not in parallel with each other in an expansion antenna whose folded part is formed by sections comprising plural split lines. CONSTITUTION:A circular parabolic expansion antenna is split longitudinally by two split lines 1a, 1b to form three folded parts 2a, 2b, 2c. The two split lines 1a, 1b forming the folded parts 2a, 2b, 2c are formed, in which the lower part is wide and the upper part is narrow, so-called, not in parallel. Thus, the antenna is folded by using the two split lines 1a, 1b not in parallel as the border, and when the antenna is contained in a head fairing of a launching rocket, it is possible to make the rate of change in the width of the middle folded part 2a closer to a change in the inner diameter of the fairing. Since the longitudinal length of the folded part 2a is formed longer, the entire shape of the antenna is enlarged.

Title: Base isolation floor
Inventor: KURIHARA MASAKI
IPC: E04F15/18
Filed: 1993-09-02
Abstract: PURPOSE:To prevent a base isolation floor from being distorted by bearing a frame by a base support device capable of moving in horizontal direction and setting multiple spring devices-acting in horizontal two dimensional directions at the support device at four corners. CONSTITUTION:When a force in horizontal direction is applied by earthquake, etc., a base isolation floor 9 is moved smoothly in horizontal direction by a base isolation support device 2, and a roller member 21 which supports a transmission bar member 22 fixed to a frame moves a movable member 16 of a horizontal spring device 5 in the direction of a rail member 17. When the base isolation floor 9 is displaced in the direction at right angles to the moving direction of the movable member 16 of the horizontal spring device 5, the transmission member 22 fixed to a frame 6 moves smoothly together with the base isolation floor 9. Therefore the horizontal spring devices 5 are arranged at right angle to each other. Then, even if any distortion is caused on the base isolation floor 9 when a computer 10, etc., is placed eccentrically on the base isolation floor 9, etc., any frictional force between the transmission roller member and transmission bar member is prevented from producing. Thus a stable base isolation performance can be exploited even if a distortion is produced on the base isolation floor.

Title: Medium conveying device
Inventor: FUJIWARA TATSUO
IPC: B65H3/06
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a medium conveying device at low cost without making it large-sized by transmitting driving force to a feeding part at the time of driving a driving part in a first direction, but not transmitting driving force to the feeding part at the time of driving the driving part in a second direction. SOLUTION: A gear 3 and a gear 5 are rotated normally by the normal rotation of a motor M. A one-way clutch 5a therefore transmits the rotation of the gear 5 to a shaft A, and a separating roller SR is rotated normally. A feed roller PR connected to the separating roller SR through a belt is also rotated normally to feed paper. Since the gear 3 is rotated normally, a one-way clutch 3a idles so as not to be able to rotatory-drive a carrier roller FR1. When the motor M is rotated reversely, the gear 3 is rotated reversely, and the one- way clutch 3a transmits the rotation of the gear 3 to a shaft C so as to rotate the carrier roller FR1 in a reverse direction. The gear 5 is rotated reversely, but the one-way clutch idles.

Abstract: PURPOSE:To automatically avoid the disabled reception of a desired station by adding a correction voltage to a tuning and a gain control voltage respectively and adjusting further the tuning frequency of an antenna tuning circuit and the gain of an RF amplifier circuit in response to the radio wave state near the reception channel. CONSTITUTION:A ROM33 stores the correction value of the gain control AGC and each tuning circuit in advance set depending on the frequency difference and level difference between a reference signal (reception signal) and a disturbing signal, a control circuit 31 selects the corresponding AGC correction value to set it into an AGC correction register. The ANT correction value selected to bias the tuning frequency of the antenna ANT tuning circuit 2 to attenuate a nearby disturbing signal is read from the ROM 33 and set in the ANT correction register 34. Then the tuning characteristic of the tuning circuit is biased to attenuate the nearby disturbing signal and the gain of the high frequency amplifier circuit 4 is set corresponding to the level of the nearby disturbing signal, then occurrent of crosstalk and the disable reception of a desired reception channel due to the AGC effect is suppressed.

Title: Presuming method for rear shaft load of tractor and trailer brake control method using the presuming method
Inventor: OE TAKESHI
IPC: B60T8/30
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To surely prevent the jack knife and swing phenomena of a trailor by computing the rear shaft load of a tractor on air suspension pressure, and compensating it through force acting on an air suspension as vehicle speed varies. SOLUTION: The rear axle load F2 of a tractor is presumedly computed on the air-suspension pressure of a tractor during acceleration, and the front axle load F1 of the tractor is computed. The brake ratios of the shafts of the tractor and trailer are computed on braking force on the front and rear shafts of the tractor and trailer and loads on a trailor shaft and the tractor front and rear shafts. The braking force on a tractor rear shaft A2 and the trailzer is controlled so that the brake ratios Z2 , Z3 , Z4 of a tractor rear shaft A2 and trailer shafts A3 , A4 may be the same as the brake ratio Z1 of a tractor front shaft A1 . Thus the brake control of the trailer is properly carried out, and jack knife and swing phenomena can be surely prevented.

Filed: 1990-08-20
Abstract: PURPOSE: To shorten the elevator running time and enhance the operating efficiency by allowing an elevator car which is going to travel in conformity to a call from a certain floor, to make priority response to a call given by its contiguous floor. CONSTITUTION: A group control device 17 compares the floor calls registered by fall call buttons 18-20 on a plurality of floors, makes designation to any call on the basis of the situations of the elevator cars 3 and 4, and gives priority to that car 3 or 4 which has destination to any floor contiguous to the floor from which the designated call is emitted. The designation is based upon the sum of the relative system-response factors of the cars 3 and 4 for each floor call registered, and the sum includes the time required to run to the calling floor, system-response factor till response, and a factor to make response to the call from the contiguous floor, and does not include the relative system- response factor for the time required to stop at the floor one beyond the applicable floor. Thus, the running time is shortened, and the operating efficiency can be enhanced.
