Title: Wiring system
Inventor: SUZAKI SATORU
IPC: H02G3/38
Filed: 1991-09-25
Abstract: PURPOSE:To provide a wiring system which can use power or information of an underfloor wiring without restriction in a layout of a furniture such as a desk, without providing plug sockets of more than necessary number and without losing beauty. CONSTITUTION:In a wiring system for connecting underfloor wiring 5 to a plug socket 2 assembled in a furniture such as a desk 1 or the like on a floor, a styluslike electrode 41 protrudes from the furniture side such as the desk 1 on the floor toward an underfloor, a conductor 51 is exposed upward from the wiring 5, and an insulation carpet 6 is laid on the floor. Accordingly, a mounting place of the furniture such as the desk is not restricted, but the furniture can be mounted at any place. Since the connection to the underfloor wiring is realized via the stylus electrode, the connection is completed merely by placing the furniture such as the desk, and the mounting is facilitated.

IPC: G01L1/00
Filed: 1990-09-18
Abstract: PURPOSE:To enable stress analysis at a crimp part of a crimp terminal by means of an experimental method without deflection to a theoretical value by pushing a taper-like jig of an approximately same shape as a part corresponding to an electric wire of a specimen into said part. CONSTITUTION:When a taper-like jig 2 having an approximately same shape as a part corresponding to an electric conductor is pushed into a photoelastic material 1 of a flat plate comprising a transparent body having a similar shape to a cross section of a crimp part of a crimp terminal A with isotropic and equal quality, a plane stress is applied to a specimen 1. Circular polarized light incident on the specimen 1 in this state is divided into two plane-polarized light in a main stress direction and having difference in phase to be emitted, is incident on a 1/4 wavelength plate 9' and decomposed/synthesized in a direction of a main axis of the 1/4 wavelength plate 9' and a direction perpendicular thereto. Then it is synthesized into plane-polarized light in a main axis direction by a polarizing plate 8' wherein the main axis is maintained at an angle of 45 deg.. The final plane-polarized light is focused by a collimator 7' and an image is formed on a screen 11 by a focus lens 10, whereby isochromatic fringe diagram can be obtained, from which stress can be analyzed.

IPC: G06F17/50
Filed: 1989-09-21
Abstract: PURPOSE:To prepare a cross-sectional graphic with high reliability with no input mistakes of dimension lines and with less man-hours in drafting processes by correcting the dimension lines and center lines simultaneously with the preparation of the sectional graphic, and adding them to the prepared sectional drawing. CONSTITUTION:A graphic position information which indicates the dividing position is sent from a tablet 12 through a coordinate input processing part 19 to a graphic division processing part 20. At the processing part 20, the graphic which is the object of division is extracted, is divided based on the coordinates which indicate the dividing position, the sectioned part is eliminated, and it is sent to a graphic moving part 23. The moving part 23 extracts the graphic to be moved in order to fill the space part caused by the elimination, moves it by a prescribed distance, and sends the graphics after processing to a dimension correction part 26. The correction part 26 extracts the dimension lines and the center line left from the graphic move, and corrects them to fit the graphic position after the movement. Further, a sectioning line is inputted by a sectioning line input part 29, and displayed through a graphic display processing part 30. Thus, the man-hours in drafting are reduced, and an input mistake for the dimension lines can be prevented.

Abstract: PURPOSE:To detect an abnormality with high accuracy irrespective of a fluctuation in a detected sheet thickness by a method wherein the flaw-detection frequency of ultrasonic waves is changed so as to obtain a resonance frequency according to the sheet thickness. CONSTITUTION:A personal computer 32 sets a flaw-detection reference frequency and a reference voltage according to coil information on an input sheet thickness or the like, and it sends them to a peak-frequency detection circuit 34 and a function generator 36. The generator 36 generates an electric signal at a frequency and a reference voltage which are set by a peak frequency detection circuit 34, and ultrasonic waves are incident on a steel plate 10 by the use of transmission probe 22A and they are received by a reception probe 22B. The received ultrasonic waves are input to a gate peak detector 42, and an abnormal particle is detected when the level of an extracted peak voltage is at a prescribed value or lower. At this time, a flaw-detection frequency shift circuit 44 shifts a flaw-detection frequency when an input peak voltage has a shape corresponding to a normal part. Then, the circuit 34 changes the flaw-detection frequency on the basis of the relationship between a sheet thickness (d)[m] and a resonance frequency (f)[Hz] when a sheet-thickness fluctuation width is at DELTAd, it finds a peak frequency at which a sound pressure becomes maximum, and it sends the peak frequency to the generator 36. Thereby, it is possible to obtain the resonance frequency according to the sheet thickness.
