Title: Method for cultivating by aeration in liquid and apparatus therefor
Inventor: ISHIDA MASAHIKO
IPC: C12N5/071
Filed: 1987-09-07
Abstract: PURPOSE:To effectively crush bubbles formed by passing a gas through an aqueous culture fluid containing organic cells, by bringing the bubbles into contact with a porous defoaming layer constituted of a water repellent material placed on a liquid surface. CONSTITUTION:An animal cell, plant cell or microbical cell is cultivated in a readily foamable liquid culture medium by aeration. In the process, bubbles formed by passing a gas through a liquid are brought into contact with a porous defoaming layer (preferably >=50% opening ratio and 2-50mm opening diameter) constituted of a water repellent material (preferably silane or siloxane) placed on a liquid surface to carry out cultivation in the liquid by aeration while crushing the bubbles. A defoaming layer is constituted of a water repellent material forming >=30 deg. contact angle between a horizontal surface and droplets of the culture fluid or a material coated or impregnated with the afore- mentioned water repellent material on the surface thereof is used as the above- mentioned defoaming layer. This method is especially effective in using an aqueous culture fluid (e.g. culture medium containing blood serum added thereto) having >=45dyn/cm<2>, especially >=90dyn/cm<2> surface tension.

Title: Engine load parameter computing device and engine control device
Inventor: HARA FUMIO
IPC: F02P5/15
Filed: 1990-08-22
Abstract: PURPOSE:To accurately and quickly compute engine load parameters by computing the engine load parameters based on a ratio of an intake air projected area to a reference area value. CONSTITUTION:Engine load parameters are determined based on the intake area projected area of a throttle valve 3' and a reference area value determined in response to the revolution NE of an engine 1, or based on the valve opening angle of the throttle valve 3' and a reference angle value determined in response to the revolution NE of the engine 1. In addition, the engine load parameters are determined based on a ratio of the intake air projected area to the reference area value, or based on a ratio of the valve opening angle to the reference angle value. By this constitution, the parameters which accurately indicate engine load at the time of the transit operations of the engine 1, can thereby be quickly computed.

Title: Video signal processing circuit
Inventor: MATSUDA NAOKI
IPC: H04N5/93
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in image quality of a still image by noise cancellation and to reduce dynamic image noise resulting from noise reduction based on a time base. SOLUTION: In the case that an input video signal is a still image, a motion detection circuit 3 inactivates a horizontal noise canceller (horizontal NC) 3 or gives an NC control signal to the horizontal NC 3, so as to weaken the activation of noise cancellation(NC) with respect to the input video signal. On the other hand, on NR control signal is fed to an NR circuit 1 so that a frame/field noise reduction(NR) circuit (correlation of an inter-frame or inter- field pattern is used to conduct noise reduction) 1 applies strong noise reduction NR to the input video signal. In the case that an input video signal is a dynamic image, the operation of the NR 1 is inactivated, or the NR control signal is fed to the NR circuit 1 so that the application of the NR is weakened with respect to the input video signal in comparison with the still image.  The NC control signal is fed to the horizontal NC3, so that the horizontal NC3 reruforces the application of the NC to the input video signal (dynamic image).

Filed: 1993-09-07
Abstract: PURPOSE:To make it possible to calculate the altitude of a vehicle even when four satellites can not be captured, by providing a first means for operating the position of vehicle, and a second means for operating the position of vehicle based on the GPS signals from a plurality of satellites. CONSTITUTION:A processing section 8 comprising a microcomputer and the peripheral equipment specifies the position of a vehicle based on a position operated by self-contained navigation based on a running distance detected based on a pulse signal from a vehicle speed sensor 3, a running direction detected by an angular speed sensor 4 and a geomagnetic sensor, and a road map data around the vehicle read out from a CD-ROM 6, and a position operated by a CPS receiver 1. Since map matching is effected and the altitude of vehicle is operated based on GPS signals from more than one satellites and a vehicle position calculated by self-contained navigation, altitude of vehicle can be calculated without increasing the volume of road map data even when four satellites cannot be captured.

Abstract: PROBLEM TO BE SOLVED: To make no influence of a vibration noise and a stress from an outside and improve stability, accuracy, and vibration-resistance by detecting a vibration change of a vibration tube by Coriolis force with a vibration detection sensor. SOLUTION: A compensation vibrator 51 is installed in parallel with a vibration tube 41, where fixed ends 52, 53 are respectively fixed to sides of both ends 47, 48 of the vibration tube 41 and supported. An excitation means 54 excites the vibration tube 41 so that torsion around a pipe axis 49 predominates. In the meantime, the excitation means 54 excites the compensation vibrator 51 so that vibration of the vibrator 51 torsion-vibrates with rotation at a center of a same axis of the pipe axis 49 or a parallel axis with it. Then, Corollas force works with torsion-vibration being at the center of the pipe axis 49 applied when a measured fluid is fed through the vibration tube 41 and an exciter 43 is activated. A mass flow can be measured by measuring an amplitude being proportionally to an the Coriolis force with vibration detection sensors 44, 45.

Title: Substitute polling device of exchange, its method and recording medium recording program for allowing computer to execute method
Inventor: SEKI TATSUYA
IPC: H04L12/70
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of a load by reducing the processing of a processor housing call-originating subscribers at a packet exchange in data communication such as personal computer communication. SOLUTION: When a called subscriber 2 is busy at the time of originating a call from a call originator 1 to the called subscriber 2, substitute polling is asked to a substitute polling processor 33 from the processor housing call- originating subscriber 31. This processor 33, instead of the call originator 1, polls to the subscriber 2, and when communication state with the subscriber becomes possible, from busy state, informs the originator 1 of the effect. Thereby, the originator 1 is enabled to set re-calling. As the processor 31 on longer has to monitor the subscriber 2 and to poll for setting re-calling, the processing is reduced to make the processor 31 free from the increase of the load.

Abstract: PURPOSE:To increase the output torque even in the low/intermediate speed operation region or in the high speed operation region, in the intake port of a multivalve type internal combustion engine equipped with a plurality of intake ports for each cylinder. CONSTITUTION:The inlet part of an intake port 5 is formed to a horizontal passage 6. An aslant passage 8 which extends in nearly stright form in inclination for a valve port axis center O toward the vicinity of the suction valve port 3 of a combustion chamber 2 is formed through a bent part 7 from the horizontal passage 6. The combustion efficiency is improved by forming a tumble in a cylinder chamber by utilizing the difference of the passage resistance on both the sides of the axis center O of the suction valve port 3 in the low or intermediate speed operation region, and the intake density on the side having the small passage resistance in the vicinity of the suction valve port 3 is increased by permitting the intake to flow into the inclined passage 8 through the bent part 7 from the horizontal passage 6 in the high speed operation region, and the influence of the part having the large passage resistance is suppressed, and the reduction of the intake efficiency in the high speed operation region is suppressed.
