Patent JP-H05164608-A (JP)
Title: Pyroelectric infrared-ray detector
Inventor: OKAMOTO KAZUTAKA
IPC: G01V8/20
Filed: 1991-12-17
Abstract: PURPOSE:To make the dead area in detection absolutely zero by partially varying the sensitivity of the received light of each electrode, and arranging the electrodes so that the sensitivity distributions are arranged in the reverse directions. CONSTITUTION:The thicknesses of regions E1 and E2, which are divided into two parts, in transmitting electrodes 2 and 3 having the equal light receiving area, are made different. The electrodes have light receiving sensitivities S1 and S2 (S1>S2) having the partially different sensitivities. The electrodes 2 and 3 are arranged on the surface of a pyroelectric ray material 1 so that the sensitivity distributions are arranged in the reverse directions. Thus, the electrodes 2 and 3 have the region E1 of the high sensitivity S1 and the region E2 of the low sensitivity S2. Since the light receiving area (E1+E2) is equal, however, the output difference is not generated in common-mode noises such as solar light, which are cast into the electrodes 2 and 3 at the same time. The noises are offset and can be removed. Since the directions of the regions E1 and E2 are reverse, the difference is generated in the amounts of the transmitted lights of the incident infrared rays based on the difference between the sensitivities S1 and S2 of the light receiving parts even if a moving body approaches from, any direction, e.g. the direction (a) or the reverse direction. The difference is detected as the output difference. Therefore, the dead area in detection can be made zero.

IPC: C01B33/42
Filed: 1991-12-18
Abstract: PURPOSE:To impart the high catalytic activity by hydrogen ions carried to the cross-linked porous body of clay by depositing the hydrogen ions in the pores of the porous body and the surface part thereof at the time of inserting inorg. pillars between the layers of laminar clay ore and producing the cross- linked porous body of clay. CONSTITUTION:The laminar clay ore (e.g.; montmorillonite) having ion exchangeability is mixed with a soln. contg. precursor ions 3 of the inorg. pillars (e.g.; Al2O3) to exchange a part of cations 2 between the clay layers 1 with the precursor ions 3 of the inorg. pillars. The ore is then heat treated at 100 to 900 deg.C to form the cross-linked porous body of clay. The porous body is mixed with an aq. ammonium salt soln. to exchange the residual cations 2 with ammonium ions 5. The cross-linked porous body of clay contg. such ammonium ions 5 is heat treated again at 200 to 900 deg.C to desorb the ammonia. The hydrogen ions 6 are thus deposited in the pores of the cross-linked porous body of clay and on the surface part thereof.

Title: Current d/a converter
Inventor: NOGI AKIHIKO
IPC: H03M1/74
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To prevent a converter output range from being decreased and to avoid the settling characteristic from deteriorating. SOLUTION: In the case of selecting VAout+, VAout- outputs, a control circuit 410 sets a low level to SB1, SB2,..., SB256 and SB1b, SB2b,..., SB256b and supplies a control signal to SA1, SA2,..., SA256 and SA1b, SA2b,..., SA256b. An N channel MOSFET receiving a high level control signal acts so as to flow a current of a current source and converter outputs VAout+, VAout- are obtained. Since no changeover switch employing a larger-sized transistor(TR) is not interposed between the resistor pairs R, R and current control sections 500a, 500b,..., 500c, it is prevented that an output range is decreased and the settling characteristic is deteriorated.

Title: Method for measuring diameter of transparent filament
IPC: G01B11/10
Filed: 1992-12-25
Abstract: PURPOSE: To measure the diameter of a filament by irradiating a fiber (filament) with a radiation beam, detecting the interference fringe and then determining the mean spatial frequency of the fringe with a sufficient accuracy. CONSTITUTION: A laser 23 generates a collimated coherent monochromatic beam 25 which is reflected and retracted in a fiber 13 to generate a remote field interference fringe. Optical systems 26, 27 project the interference fringe onto left and right detectors 29, 31. The detectors 29, 31 have centers at +61.5 deg. and -61.5 deg., respectively. An appropriate angular collection range for each detector is 20 deg., i.e., it is from +55.5 deg. to +71.5 deg. for the detector 29 and from -51.5 deg. to -71.5 deg. for the detector 31. Output from each detector is analyzed separately in order to obtain a signal representative of the diameter of the fiber. When two signals representative of the diameter of the fiber are generated, they are averaged in order to obtain a desired final signal representative of the diameter of the fiber and insensitive to the ellipcity of the fiber.  In other words, they are added and divided by 2.
