Title: Measuring apparatus for liquid level
Inventor: POORU NAIJIERU RICHIYAAZU
IPC: G01F23/284
Filed: 1992-09-24
Abstract: PURPOSE: To measure a liquid level under a high temp. and high pressure condition with high reliability by directly measuring the liquid level by using a time region reflecting measuring method using short high frequency pulses reflected from the surface of a liquid. CONSTITUTION: The shell 10 of a probe communicates with the interior of a boiler and the space 14 above water 13 is filled with pressurized steam. A steel rod 15 is supported on a constant position ring 16 at its lower end and the upper end thereof is attached to a titanium rod 17. The upper end of the rod 17 is connected to a titanium tube 18 by a collar 19. The probe is filled with a liquid up to a level to be measured and the upper part thereof is filled with steam to send high frequency pulses to the upper end of the probe from a coaxial feeder 21. The probe has a first discontinuous part generating reference pulses in the vicinity of its upper end and the distance between the surface of the liquid and the first discontinuous part is calculated from the reference pulses and the reflected pulses from the surface of the liquid.

Title: Fingerprint sensor provided with hologram guide
Inventor: IGAKI SEIGO
IPC: G06T1/00
Filed: 1989-09-28
Abstract: PURPOSE:To improve convenience to use by reproducing a guide for guiding the finger of a fingerprint sensor part on a fingerprint input plane or its neighbourhood by a hologram. CONSTITUTION:The hologram 12 is arranged on the fingerprint input plane 10. The finger or a pattern for guiding the finger, for instance, is used as the pattern of the hologram, and by irradiating the hologram 12 by a lighting light source 13 arranged below a light transmission plate 11, its reproduced image 14 is generated below the fingerprint input plane 10. Accordingly, since guide information to be the guide of the finger 5 can be generated as the reproduced image by the hologram 12 on the fingerprint input plane 10 or its neighbourhood, the finger needs only be arranged along this hologram image. Thus, the fingerprint sensor of good convenience to use free from such an accident that the finger is nipped by the guide from it both sides can be obtained.

Title: Form paper with watermark
Inventor: OKAMOTO SOJI
IPC: B42D15/10
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To provide a form paper with a watermark, in which no change occurs with time and a watermarked ensign part can be easily formed. SOLUTION: A light shielding ink made of an ultraviolet curing type paper color ink is formed locally on the surface of a base paper 3 so as to partitioningly form a watermarked mark part 2 due to the difference of the transmissiovies of a surface part, on which the light shielding ink is coated by printing, and that of a surface part, on which no light shielding ink is coated, in order to allow to visually recognize the watermarked ensign part through the transmission of light so as to constitute a form paper with a watermark. Thus, since the ultraviolet curing type paper color ink is employed, no change with time occurs unlike in a constitution of employing impregnation with an oily ink, and a fine design representation also becomes possible and, at the same time, no conspicuity beyond the surface of the paper develops.

Title: Manipulated variable controller
Inventor: HORIKOSHI KOICHI
IPC: F16D28/00
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To attain various stroke amounts without changing the stroke amount of actuator's own by fitting a member to be operated which is entrained in the displacement direction with an operating member when the operating member is displaced by over a prescribed range from one end of its displacement range. SOLUTION: A member 66 to be mounted displaces together with the displacement of a piston rod 56 caused by the extension or retreat of an actuator 42. When the axial position of the member 66 to be mounted in the piston rod 56 or an extension member 62 changes, the distance of the member 66 to be mounted from the prescribed stationary point 46 of the actuator 42 changes in the displacement direction of the member 66 to be mounted, and the manipulated variable of a member 64 by the member 66 to be mounted changes. By changing the axial mounting position of the member 66 to be mounted in the piston rod 56 or its extension member 62, it is possible to set the manipulated variable of a member 64 to be operated arbitrarily.
