Title: Measuring device
Inventor: NANBA MAKOTO
IPC: G01F23/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To accurately detect a fine change of a liquid level, and obtain the accurate liquid level rising factor, in flow guantity and out flow guantity by obtaining a difference between the liquid level measuring signal, which shows the liquid level of the liquid to be detected inside a predetermined container and the signal obtained by processing the waste time of this liquid level measuring signal. SOLUTION: A difference between the liquid level measuring signal 1, which shows the liquid level of the liquid to be detected inside a predetermined container, and the signal obtained by processing this liquid level measuring signal with a water time processing unit 2 is obtained by a subtraction processing part 3. A result of this computing and a predetermined multiplier setting 5 are multiplied by a multiplying unit 4. In a group of a function, of which transmission function is obtained by multiplying a desirable element by a differential element, the liquid to be detected is measured on the basis of a result of this computing.  In the case where change of liquid level is assumed constant, since change of the liquid level measuring signal with a constant time interval becomes large in proportion to the time interval, change of the liquid level can be recognized large even in the case of a fine change of the liquid level, and influence of a quantization error can be reduced.

Title: Controller for supply speed of parts
Inventor: AOYAMA YOSHITAKA
IPC: B65G47/14
Filed: 1995-12-09
Abstract: PROBLEM TO BE SOLVED: To improve the durability of an engaging tube by forming a control face for optimizing the advancing speed of parts in the end of a passage for introducing parts into a guide cylinder and thereby preventing an engaging projection from being worn. SOLUTION: A stud bolt 16 sent from a supply hose 34 enters a passage 25, striking a control face 27, moving to a guide cylinder 1 by air from an injecting port, falling and stopping with the flange 18 caught by an engaging projection 9. With a supply rod 2 lowering, the shaft 17 enters a receiving hole 20 and is attracted by a magnet 22. With the tip end of the supply rod 2 coming into contact with the flange 18 and pushing it down, the flange 18 strongly strikes the engaging projection 9, elastically expanding the tip end of an engaging tube 5, passing through the engaging projection 9, and reaching a target place through the operation of an air cylinder 13. Thus, the control face 27 reduces the speed of the stud bolt 16, preventing the wear of the engaging projection 9, and thereby enabling the durability of the engaging tube 5 to be improved.

Title: Optical lens
Inventor: KITAGAWA HISATAKE
IPC: G02B13/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical lens saving a space, having a short focal distance and capable of compensating chromatic aberration even by the single lens by forming aspherical surfaces on both surfaces and a diffraction surface on one side. SOLUTION: Both surfaces (refraction surfaces) 2, 3 of an optical lens 1 are formed to be aspherical surfaces and one side of the surfaces is formed to be a diffraction surface 4. When this lens is a single optical lens 1,, since the aspherical surfaces are formed on both surfaces (refraction surfaces) 2, 3 and the diffraction surface 4 is formed on one side, various aberrations such as the distortion aberration are compensated. Consequently, the chromatic aberration of an image position is compensated while it is impossible for a refractive single lens heretofore. Thus, this lens is used for an image pickup device composed of an optical system having a very short focal length such as a small camera as the optical lens 1.  Namely, even if it is at least a single lens, the optical lens capable of compensating the chromatic aberration, saving the space and having a short focal distance is obtained.

Title: Portable communication equipment and reception method
Inventor: MARUYAMA KOJI
IPC: H04B1/10
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a portable communication terminal equipment that eliminates an interfering wave in the vicinity of a reception desired wave, without the use of an intermediate frequency filter having a steep attenuation characteristics. SOLUTION: A reception power measurement section 31 measures reception electric field intensity, and a code error rate detection section 32 measures a code error rate for error correction of a base band signal. When the code error rate is not negligible in spite of excellent reception electric field intensity, it is discriminated that the reception signal is affected by an interfering wave. A frequency control section 33 changes a local oscillation frequency of an RF local frequency oscillator 17 and a reception IF local frequency oscillator 21 or the like to deviate the frequency of the reception signal converted into an intermediate frequency signal. Thus, the interfering wave in the vicinity of a desired wave is eliminated by a reception IF band-pass filter 18 as signal of frequencies outside the pass band of a reception IF band-pass filter 18.
