Patent JP-H08178641-A (JP)
Title: Acoustic displacement gage
Inventor: ISHII YASUSHI
IPC: G01B17/00
Filed: 1994-12-20
Abstract: PURPOSE: To eliminate the influence of temperature changes, etc., to enable accurate displacement measurements by detecting through changes in phase of sound pressure the displacement of an object to be measured. CONSTITUTION: A sound source 1 produces sounds by causing vibration of a diaphragm 11 by a current (i) from an oscillator 3. The sounds produced are emitted to the outside through a measuring hole 12, and the surface of an object 2 for measurement is at a distance (d) and opposite to the front of the hole. A branch pipe 14 guides the sound pressure (p) within the sound source 1 to a microphone 4. An output of the microphone 4 is amplified by an amplifier 5 and converted to a sound pressure signal (e), which is then input to a phase meter 7 via a filter 6. A reference signal (r) in phase with the signal (i) from the oscillator 3 serves as another input to the phase meter 7 via a filter 6'. The phase meter 7 issues a signal E, proportional to the phase θ of the signal (e) and displays the signal Eθ in a meter 8, the signal (r) being the reference for the signal (e). Since the phase of the sound pressure varies sharply with changes in acoustic impedance inside a gap at the end of the measuring hole 12, the distance (d) between the measuring hole 12 and the surface of the object 2 is detected by changes in phase of the sound pressure.

At the irradiation, the number of secondary electrons released from a plurality of pads 43a and 43b is detected by a secondary electron detector. Further, the detected number of secondary electrons is compared and imaged in black or white, for judging occurrence of a shallow pit 45 on the semiconductor substrate 31.

Filed: 1989-12-27
Abstract: PURPOSE:To make it possible to measure many samples instantaneously by adding antibodies for hidden epitope (he) in a free L chain (FLc) to the sample, and measuring the L chain by a nephelometric (BN) method. CONSTITUTION:FLc is present especially in the sample of a renal insufficiency patient or the like among the samples of blood and the like. In an L chain, a receptor which displays antigen property when (he) is freed is present. When an antibody such as a kappaL chain which relatively reacts with the (he) is used for the receptor, an antigen-antibody complex is formed in the precipitaion reaction in the solution of the sample. Then the antigen-antibody complex is measured by a BN method. Namely, near infrared rays whose light source is an LED and wavelength is about 840 nm are used, and the scattered light from the antigen-antibody complex is measured as a nephelometric method. In detail, a BN analyzer is used, and the concentration of the L chain is computed based on the difference between the scattered lights before and after a specified time, e.g. about 10 seconds after and about 12 minutes after the mixing of the antibody into the sample.

Title: Commodity carrying-out structure for automatic vending machine
Inventor: KANBE AKIRA
IPC: G07F11/28
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a commodity carrying-out structure for an automatic vending machine which can prevent commodities from being carried out in a jumping state and, in addition, can make various kinds of commodities to be carried out surely without increasing the inclined angle of a commodity shelf. SOLUTION: When a rack 44 is moved forward and backward by operating a solenoid 46, pinions 424 and 433 rotate and first and second stopper members 42 and 43 make frequent appearances on the upper surface of a commodity shelf 41. Consequently, the commodities on the shelf 41 are successively carried out from the foremost commodity A1. While the commodity A is carried out, the frequent appearance making speeds of the stopper members 42 and 43 are temporarily made slower by decelerating the moving speed of the rack 44 in the forwardbackward direction on the way of moving. Since the protruding speed of the second stopper member 43 to the upper surface of the shelf 41 is temporarily made slower, the front end of the member 43 does not strongly send the commodity A flying even when the front end comes into collision with the commodity A1.
