Patent JP-S6222016-A (JP)
Title: Distance detector
Inventor: NAKAZAWA KOJI
IPC: G02B7/32
Filed: 1985-07-23
Abstract: PURPOSE:To adjust an automatic focus with few errors by photodetecting a reflected pulse from an object and deducing distance information to the object from two signal variation detecting signals of the output. CONSTITUTION:When the pulse light which is emitted with an infrared light emitting diode LED 11 and projected from a projecting lens 12 is irradiated on the object 1, the light is reflected by the object 1 and is formed an image on a photodetector 14 by an image-forming lens 12 located at the position separated from the LED 11 by the base line length S. Here, the detector 14 which is impressed with the reference voltage Vref on a central terminal 14a0 is constituted so that the variations i1 and i2 of a photoelectric current are flowed in both terminals 14a1 and 14a2 respectively by photodetecting the pulse light. Consequently, when i1/i2 is calculated with a distance measuring arithmetic circuit 15, this value is made the value corresponding to a distance (l) between the detector 14 and the object 1. In this way, the automatic focus adjustment is realized by controlling the quantity of movement of a photographing lens of a camera by the output of the circuit 15.

Title: Guarding equipment
Inventor: KOMATSU YOSHINORI
IPC: G08B13/12
Filed: 1990-06-21
Abstract: PURPOSE:To always secure constant detecting sensitivity and to obtain the high reliability of guarding to the intruders by producing an alarm when the change of the output signal of a differential trans-sensor accordant with the bending degree of a detecting wire due to the external force exceeds the detecting threshold. CONSTITUTION:A detecting wire 3 is held by an intruder and therefore bent, and therefore a core 11 suddenly displaces in the direction A by a necessary extent. Thus the output signal of a differential trans-sensor 10 has a sudden increase change in the plus (+) direction. When the change level of the output signal exceeds the plus (+) threshold, the H-level output is produced from a comparator 19 for a period of time shorter than the delay time of a delay circuit contained in a plus (+) side reference signal production circuit 16. Then the H-level output defined in a prescribed short period is inputted to a digital processing circuit 22 via on OR circuit 21. At the same time, an information production signal is outputted and an alarm is produced from a buzzer, etc. Thus the presence of an intruder is immediately informed. As a result, the high guarding reliability is secured and the peripheral guarding is effectively attained for the buildings.

IPC: H01G4/14
Filed: 1988-06-29
Abstract: PURPOSE:To miniaturize a capacitor and increase capacitance thereof while imparting high reliability by detecting the state, in which molecules are filled most densely, by using an amperometric method and determining the conditions of preparation when a dielectric thin-film in which monomolecular films filled with molecules most densely by employing a Langmuir-Blodgett's(LB) method are accumulated is formed. CONSTITUTION:An aluminum electrode as a lower electrode 2 is shaped onto a glass plate as a substrate 1 through vacuum deposition. Surface pressure-area (pi-A) characteristic and current-area (i-A) characteristic are measured and evaluated simultaneously in order to determine the conditions of preparation before arachic acid is changed into a thin-film by using an LB method. An aluminum thin-film is prepared onto a monomolecular accumulating film shaped as a dielectric layer 3 through a vacuum deposition method as an upper electrode 4. Accordingly, the dielectric constant of arachic acid as a bulk crystal can be increased sufficiently by preparing the dielectric layer under the state of the most-dense filling of monomolecular films.

Filed: 1989-06-23
Abstract: PURPOSE:To prevent the malfunction of a reception level alarm by providing a comparator comparing the reception levels of different polarized waves and outputting a reception alarm when a difference between both reception levels is a prescribed difference or above. CONSTITUTION:A V polarized and H polarized wave receivers 2, 2' are con nected to an antenna 1. Suppose that the reception electric field of a different polarized wave is a point A and that of its own polarized wave is a point B in figure, when the point B is less than a threshold level (point) C of a recep tion electric field or below, an alarm should be issued. However, there is the leakage D of a different polarized wave from an axial ratio identification XPD or the like of the antenna 1 and the level is detected as B', then no alarm is issued from discriminators 4, 4'. Then the reception level detection voltage of the detectors 3, 3' is inputted respectively to the comparator 5 and when there is a difference over the voltage D corresponding to the XPD in the detec tion voltage of them, an alarm is outputted from the comparator 5 to the receiv er with a lower voltage. Thus, the malfunction not issuing an alarm due to the effect of the XPD is prevented.

IPC: A61B5/117
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To make a finger print easily visible and moreover, facilitate the transferring thereof even with limited degree of adhesion thereof by exposing an specimen with the finger print thereon to a vaporized atmosphere of cyanoacrylate ester and a sublimating dye to detect the finger print. SOLUTION: In the formation of a colored finger print image on a specimen with the finger print thereon, the specimen to which the finger print probably adheres is placed into a closed box and exposed to cyanoacrylate ester heated and vaporized by a heater or the like to form a finger print image.
