Title: Magnetic bubble memory element
Inventor: KONDOU HIRONORI
IPC: G11C11/14
Filed: 1983-12-16
Abstract: PURPOSE:To prevent surely generation of malfunction of a detector by making the pattern shape different from a main detecting line and a dummy detecting line so as to increase uncancel noise thereby obtaining a detection output with high S/N ratio. CONSTITUTION:A meandering pattern 2b is connected in series with a pattern 2a in a dummy detecting line 2' corresponding to the main detecting line 1. In this case, the meandering pattern 2b has a pattern part extending in a direction orthogonal to the direction of the flowing of the detection current I and its resistance value due to magnetoresistance effect is increased when an in-plane rotating magnetic field 8 is directed in the direction of 90 deg. and 270 deg.. Through the constitution above, the uncancel noise is negative at the phase of 90 deg. and 270 deg. of the in-plane rotating magnetic field 8. Thus, the resistance value with the main detecting line 1 is unmatched and the S/N ratio is improved.

Title: Output circuit
Inventor: HAMAGUCHI MASANAO
IPC: G06F3/023
Filed: 1990-09-05
Abstract: PURPOSE:To switch the output electric characteristics of an output terminal and to use the switched characteristic by selecting a specific driver circuit out of plural ones based upon a control signal. CONSTITUTION:When the level of a control signal S is 'L', the output level of a NAND gate 8 is turned to 'H' independently of the level of an input signal I to turn off a p-channel type FET 3 and the output level of a NOR gate 11 is turned to 'L' to turn off an n-channel type FET 4. At this time, an 'L' level signal is outputted from an n-channel type FET 2 to an output pad 5. Thus, output electric characteristics corresponding to the p-channel type FETs 1, 2 are outputted by selecting a driver circuit D1. When the level of the control signal S is 'H', an output signal corresponding to the electric characteristics of the FETs 3, 4 can be similarly outputted by selecting a driver circuit D2.

Abstract: PURPOSE:To supply always a proper amt. of raw material on a calender roll, by irradiating a slit light on the central part of calender rolls, photographing a cut face with a irradiated light by means of an area sensor camera and analyzing it. CONSTITUTION:A slit light is irradiated at a vertical direction - 30 deg. with respect to the central vertical axis of two parallel rolls 1 of a calender apparatus and a cut face with a irradiated light is photographed by means of an area sensor camera at 15 - 45 deg. in the opposite direction of a lighting device 4 with respect to the vertical axis. An amt. of raw material yield on the calender rolls is determined from the data of the cut face obtained to make an amt. of a raw material supplied on the calender rolls 1 to be proper and to make the amt. of raw material yield on the calender rolls 1 to be constant. Because the lighting device 4 is set to be able to irradiate the central part of the calender roll like this, the lower level of the resin raw material between rolls which has been hitherto hardly detected can be measured.

Title: Plastic container and composite container using it
Inventor: FUKUSHIMA HIDEO
IPC: B65D77/06
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a plastic container excellent in low temperature drop strength, transparency, and moisture-proof property by performing the stretch blow molding of the plastic resin with the prescribed ethylene content. SOLUTION: In manufacturing a plastic container to store the liquid, powder or granular content through blow molding, polypropylene of 5-35% ethylene content is used. When the ethylene content is added to polypropylene, the low temperature impact strength can be improved because polypropylene is difficult to constitute the crystalline structure and ethylene content enters between crystals of polypropylene. The polyolefine resin to be blended in the polypropylene resin is selected among the resin group such as low density polyethylene-α olefin copolymer, and the low density polyethylene in the range of 0.88-0.93g/cm<3> in density, and 1-30g/10min. of melt-flow rate at the temperature of 19oC and 2,160g of load is selected.

Title: Plant diagnostic device
Inventor: TAMURA SEIJI
IPC: G08B31/00
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To separate and identify whether an abnormal position exists in a physical system or a measuring system by inputting measured values corresponding to single/ joint mathematical models, and comparing estimated values with the actual measured values. SOLUTION: The reaction liquid flow of a reaction vessel 2 and the pressure in the vessel 2 are measured by measuring systems Wm , Xm respectively, and cooler inlet/outlet temperatures are measured by measuring systems Ym , Zm . When the measured values are inputted, an arithmetic unit F1 sets the single mathematical model expressing the relation between the flow W and reaction pressure X, and an arithmetic unit F2 sets the joint mathematical model expressing the relation between the flow W and cooler inlet temperature Y, for example. A comparator C1 (C2 ) compares the measured value X(Y) with the estimated value x (y) of the arithmetic unit F1 (F3 ), and a comparator C12 compares the measured value Y with the estimated value y0 of the arithmetic unit F12 respectively for coincidence or noncoincidence.  When a liquid leak occurs on a pipe 1, for example, an abnormality is detected by the compared results of the comparators C1 , C12 . When the pressure detector of the measuring system Xm fails, the comparators C1 , C2 indicate an abnormality, however the comparator C12 indicates a normality. An abnormal position can be separated and identified by the combination of these judged results.

IPC: G01J1/04
Filed: 1994-09-30
Abstract: PURPOSE: To obtain an infrared detector having simple structure in which the oscillation angle can be set freely and a correct oscillation angle can be sustained constantly with no fluctuation in the center of oscillation while reducing the cost. CONSTITUTION: A rotary plate 9 is oscillated reciprocally by a reversible motor A through a transmission wheel train B. An infrared sensor 11 is mounted on the rotary plate 9 and a photosensor 12 detects that the infrared sensor 15 located in the center of oscillation L-L. A control means for the reversible motor A feeds positive drive pulses corresponding, in number, to the oscillation angle. Upon finishing the forward rotation caused by the positive drive pulses, a reverse drive pulse is fed to the reversible motor A and when the motor A rotates reversely to deliver an output again to the photosensor 12, same number of reverse drive pulses are fed. Upon finishing the reverse rotation caused by the reverse drive pules, a positive drive pulse is fed to the reversible motor A which thereby rotates in the positive direction and returns back to the original position.

Title: Analog/digital converter
Inventor: SUZUKI TAKASHI
IPC: H03M1/06
Filed: 1989-09-13
Abstract: PURPOSE:To always output the digital signal of a prescribed waveform by changing a reference voltage by means of adjusting it to the fluctuation of the center voltage of an analog input signal and always holding a difference between the center voltage of the analog input signal and the reference voltage to be constant. CONSTITUTION:When the center voltage VSG of the analog input signal becomes high owing to the change of a peripheral temperature and a secular change, a negative signal is outputted from a comparator 21 and a heater 19 is heated by a switch 22. Consequently, the voltage drop of a temperature compensation element 14 becomes small and the potential of a threshold voltage Vth becomes high. Consequently, the difference between the center voltage VSG and the threshold voltage Vth can be held to a set point deltaVO. Thus, the digital waveform of the prescribed waveform can always be outputted even if the center voltage of the analog input signal fluctuated owing to the peripheral temperature.

Title: Detection of position of defect and of open end of optical fiber
Inventor: FURUKAWA SHINICHI
IPC: G02B6/00
Filed: 1987-09-22
Abstract: PURPOSE:To enable the setting of a cursor automatically and at a high accuracy with a optical pulse tester, by determining a difference in a back scattered power between two positions with a section range of vtau/2 as obtained when an optical pulse is sent with a pulse width (tau). CONSTITUTION:First, a difference is determined between positions separated by + or -vtau/4 with a desired position (z) as center on a back scattered waveform. Then, it is judged how the difference value varies with respect to a distance. Then, when the difference varies in steps, the position separated by vtau/4 from a changing point zB is determined to be the position of a defect or an open end. When the difference value does not vary in steps, a position zB is determined at which the difference value reaches the max. or the min. within a distance section where the difference value exceeds a specified value. Moreover, the position closer to the incident end side by vtau/4 from the zp is determined to be the position of the defect. This permits an operator of an optical pulse tester to set a cursor automatically and accurately.
