Title: Flaw inspection method
Inventor: HAYANO FUMITOMO
IPC: G01N21/93
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To shorten to a great extent the setting time for the sensitivity control data according to the sensitivity in sensing operation over a wide range. SOLUTION: The first flaw inspection device acquires sensitivity control data for a plurality of reference particles having a size corresponding to the size of a flaw 10 to be sensed, and flaw inspection is made using the data as reference, and the following flaw inspection devices measure the sensitivity control data for at least two among the reference particles, and the sensitivity control data for the remaining reference particles is determined on the basis of the measured data and corresponding reference data, and the inspection of flaw 10 is conducted using the applicable control data and the measured control data. Therefore the sensitivity control data can be determined easily, and the setting time of the sensitivity control data according to the sensitivities in the sensing operation over a wide range can be shortened to a great extent.  Thus an improved flaw inspection method is established.

Title: Method for driving solid-state image pickup device
Inventor: AKIYAMA TOSHIYUKI
IPC: H04N5/335
Filed: 1983-03-18
Abstract: PURPOSE:To decrease or eliminate a reset noise component by adjusting the width of a reset pulse and the position of a transfer pulse driving an output amplifier circuit and setting a signal charge holding time and a reset noise holding period of an output signal so as to satisfy a specific equation. CONSTITUTION:There is a time difference of DELTA=(T-taur-r)/2 between the signal pulse train and the reset noise pulse train of an output signal shown in Fig. (C), and the difference DELTA is set to 0-T/2 by adjusting the width taur of a reset pulse phiR and the signal charge holding time tau. Thus, the difference DELTA is matched to a phase difference pi/2+npi of a carrier of an m-order harmonic of the output signal and DELTA=(pi/2+n)/(momegap) is attained (where n=0,1-m-1), then the signal component is extracted by the synchronous detection multilying the carrier of the m-order harmonic of the signal pulse train in Fig. (C) onto a local signal cos(momegapt). Since the carrier of the m-order harmonic of the noise pulse train is shifted by 90 deg. to the local signal, no noise component is detected. The setting condition to the width of the phiR and the tau is determined as tau+taur=T(2m-2m- 1)/2m (where m=1,2...).

Title: Activation of drug soluble in alkali and acid
Inventor: MOTOYAMA SHIMESU
IPC: B01F1/00
Filed: 1979-04-13
Abstract: PURPOSE: To obtain a drug having improved dispersibility, without using an organic solvent, by depositing the drug, which is a solid at normal temperature, sparingly soluble in water, soluble in aqueous alkalis or acids, and dissolved in an aqueous solution.  
     CONSTITUTION: A drug, e.g. Phenytoin, Nalidixic acid, or Sulfisoxazole, which is a solid at normal temperature, sparingly soluble in water, and soluble in aqueous alkalis or acids, is dissolved in an aqueous alkali or acid containing a water-soluble  high polymer, e.g. a thermally gelatinized high polymer. The solution is then  neutralized with an acid or alkali to deposit the drug, which is separated and dried  to form a drug having improved redispersing properties in water, i.e. in digestive  tracts. This method is applicable only to drugs soluble in alkalis or acids, however,  eliminates the use of organic solvents.

Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a winding control system and a core that all permit efficient and reliable control data transfer for and finishing control of a material to be wound up. SOLUTION: A core with a carrier is set in a winding part 11. A finishing machine control part 25 for a finishing machine feeds winding data produced during a winding process into a record data originating part 23 for the winding part 11. The record data originating part 23 processes the winding data into record data and passes it to a writer control part 21, which in turn writes it into the core carrier. In the next process, the core on which a material is wound up in the preceding process is placed in an unwinding part 15. A reader control part 27 provided for the unwinding part 15 reads the winding data out of the core carrier and supplies it to a control data originating part 29, which in turn converts it into control data and passes the obtained data to the finishing machine control part 25.  The finishing machine control part 25 then allows a winding process on the basis of the control data.

Title: Binary system vacuum evaporator device and operating method thereof
Inventor: HODOZUKA MASATOSHI
IPC: B01D3/10
Filed: 1994-03-16
Abstract: PURPOSE:To previously maintain the pressure and the heating temperature in a vacuum evaporator in such a state as unstable and unreasonable phenomena are not generated in the vacuum evaporator by interposing the flow meter of steam in a steam pipeline and connecting a vacuum pressure-regulating valve to the inlet of the vacuum evaporator and also connecting the flow meter of distillate to a condenser. CONSTITUTION:The flow rate of steam flowing through a steam pipeline 10 is measured by the flow meter 11 of steam or the flow meter 15 of distillate. When an unstable state such as generation of plenty of evaporated steam is generated, a characteristic chart is used which has been obtained by the measured values of both the pressure in a vacuum evaporator 3 through a pressure gage 7 and the heating temperature thereof through a thermometer 8. When the existing flow rate of evaporated steam is more then that of supplied liquid, the pressure in the vacuum evaporator is raised and the pressure value in the vacuum evaporator is calculated so as to regulate the existing flow rate of evaporated steam to the same flow rate as the flow rate of supplied liquid. On the other hand, when the existing flow rate of evaporated steam is little, the low pressure value in the vacuum evaporator is calculated. Then, a vacuum pressure-regulating valve 14 is operated, so that the existing pressure in the vacuum evaporator is regulated to the now calculated pressure value in the vacuum evaporator. Thereby, the vacuum evaporator is controlled in a balanced stationary state.
