Title: Measurement of radiation density for radioactive dust
Inventor: AOKI YASUHIRO
IPC: G01T1/167
Filed: 1991-08-15
Abstract: PURPOSE:To achieve a highly reliable calculation of radiation density by a method wherein initially for a specified time back ground is measured and stored with a plurality of data with which a plurality of populations composed of different number of the data are set and at each measurement of radiation density a similar data is obtained in a short time and the population which the data belongs to is judged to determine an weighted means therewith. CONSTITUTION:For example, fifteen measured values are obtained as radiation data initially from a radiation detector 12 to be stored in a memory 22. First, second and third populations with different number of data are set from the fifteen data to calculate means and standard deviations separately. Then, a pump 8 is started to perform a measurement of a radiation density. After the end of the measurement, a background measurement is performed in a short time with the detector 12. As for the data obtained, which of the first, second and third populations the data belongs to is judged depending on whether the deviation value from a population is less then a value three times as much as the standard deviation of the popylations and a weighted mean with the belonging population is obtained and the values obtained is stored in the memory 22. Thus, variations in the background is detected accurately thereby reducing the effect thereof.

Title: Fan
Inventor: KUWAJIMA KOTARO
IPC: H02K7/14
Filed: 1991-08-16
Abstract: PURPOSE:To reduce the frictional noise and wind cut noise and improve the blowing efficiency by varying the magnetic field of a coil in succession to the direction for revolving a blade wheel. CONSTITUTION:Serveral coils 6 arranged in a casing 3 form a linear motor between permanent magnets 2 which are arranged at equal intervals on the outer periphery of the rim 1b of a rotary blade wheel 1. In order to revolve the rotary blade wheel 1, it is enough to vary the magnetic field of the coil 6 in the direction for revolving the blade wheel 1 in succession. When the blade wheel 1 starts revolution, the blade wheel 1 is floated up by the linear motor, and a bearing 5 and the rim 1b of the blade wheel 1 are brought into a noncontact state, and the generation of friction is prevented. Further, since an article which resists the flow of air does not exist before and behind the blade wheel 1, the blowing efficiency is improved. Further, since the gap between the blade wheel 1, casing 3, and a gide body is small, the wind cut noise can be prevented.

Title: Pump drive controller in hydraulic pressure brake booster system
Inventor: ISHII TOMOYUKI
IPC: B60T17/22
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To accumulate pressure in an accumulator precisely even upon an abnormality in the pump drive controller of a hydraulic pressure brake booster system, and raise the alarm precisely. SOLUTION: While an ECU 13 operates normally, a safety relay 18 is switched on to set its first and second changeover switches 20 and 21 on contacts (a) and (c). This setting causes a motor 9 and an alarm device 14 to be controlled by the ECU 13 according to the signals that a pump-drive pressure sensor 11 outputs. If the ECU 13 or its connectors 13a malfunction, on the other hand, the relay 18 is switched off to set the first and second switches 20 and 21 on contacts (b) and (d). This setting causes the motor 9 to be drivingly controlled directly by the signals that the pressure sensor 11 outputs, which permits the drive control of a pump and thus the accumulation of pressure in an accumulator even on an abnormality in the ECU 13; and causes the alarm device 14 to operate independently to light its alarm lamp on.

Title: Production of magnetic disk
Inventor: TAKAHASHI JUN
IPC: C09D5/23
Filed: 1986-09-03
Abstract: PURPOSE:To eliminate the formation of pinholes of a coated film and to reduce noise by using a mixture contg. 70-90wt% barium ferrite powder having 10-30 planar ratio and 10-30wt% barium ferrite powder having 3-5 planar ratio as magnetic powder on a disk substrate. CONSTITUTION:The mixture contg. at least 70-90wt% Ba ferrite powder having 10-30 planar ratio, more preferably 0.15-0.20 grain size and 20-30 planar ratio and 10-30wt% Ba ferrite powder having 3-5 planar ratio, more preferably 0.05-0.07 grain size and 3-5 planar ratio is used as the barium (Ba) ferrite magnetic powder. The Ba ferrite magnetic powder can be horizontally oriented on the substrate and the coated film which does not generate the pinholes is obtainable by increasing the grain size distribution of the Ba ferrite powder. The Ba ferrite powder contains the magnetic powder having the small grain size and planar ratio and since the magnetic powder having such small grain size and planar ratio has poor orientability, the powder flocculates and the orientation is thereby hindered.

Abstract: PURPOSE:To improve the accuracy of computation in the next process by sending an unexpressive flag when the computed result of floating point data goes to an unexpressive low value, and setting an output result at zero or an outputtable minimum value. CONSTITUTION:To the output side of an arithmetic circuit 1, an underflow detection circuit 2 which detects the fact that the computed result of the arithmetic circuit 1 goes to a value less than zero and sends an underflow flag, an unexpressiveness detection circuit 3 which detects the fact that the computed result goes to a value less than -128 and sends a signal of 0 or 1 representing unexpressiveness, and a computed result sending circuit 13 are connected. In other words, the unexpressiveness detection circuit 3 sends a flag representing the unexpressiveness when the computed result of the floating point data goes to a very low value and an unexpressive value. Also, a floating point arithmetic unit sets the output result at zero or the outputtable minimum value. In such a way, it is possible to improve the accuracy of the computation of a floating point.

Abstract: PURPOSE:To mitigate the rapid increase/decrease of the injection quantity during rapid acceleration/deceleration by providing a dash pot allowing an injection quantity control member to operate slowly when an external action member is abruptly operated on the injection quantity control member of a fuel injection pump. CONSTITUTION:If an acceleration pedal is depressed for rapid acceleration during an idling operation when the position of a control sleeve 31 is determined by the balance between the thrust of a governor sleeve 40 due to the expanding action of a flyweight 41 and springs 36, 45, and spring 45 is pulled to the left through a lever 48, shaft 47 and throttle lever 46 connected to the accelerator, and a tension lever 34 is abruptly rotated counterclockwise. Since the dash pot 50 is connected to the tip of said lever 34 at this time, when the tensile force toward the left direction is applied to a rod 53, the pressure inside of a housing 51 becomes negative, thus the rotation of said lever 34 is mitigated and said  sleeve 31 is slid at a proper speed.

Abstract: PURPOSE:To contrive to prevent the lowering of tensile strength of a band by heat-treating both ends of the embossed band made of crystalline thermoplastic resin at the temperature equal to or higher than the melting point of blank resin along its longitudinal direction. CONSTITUTION:To prevent effectively the occurrence of cracks in an obtained band and to keep the tensile strength required for the band in longitudinal direction, the width W2 of the raw fabric after drawing is caused to be in the range of W1W2>=0.5W1. The stretched blank fabric (a) is slit into a specified width of a band by a slitter 12 and made into a plurality of bands, and then they are advanced to rolls 13, 14. Both endmost bands of the slit bands are separated as trimming loss. They are recovered in separate operating line and reused. Residual bands are embossed by pressing, using a pair of rolls 15, 16 having unevenness on surfaces. By heating both ends of the embossed band to the temperature equal to or higher than its melting point, said both ends materials are restored to unstretched state and lose the directional property of molecular orientation. The notch effect caused by embossing is eliminated, and the lowering of tensile strength in longitudinal direction is prevented.
