Title: Optical displacement sensor and driving system using it
Inventor: ISHIZUKA AKIRA
IPC: G01D5/38
Filed: 1992-12-17
Abstract: PURPOSE:To miniaturize a sensor and improve the accuracy and resolution of the sensor by providing an optically functional element which emits light by splitting the light into a plurality of luminous fluxes and another optically functional element which guides reflected light modulated by a relatively-displaced object to a light receiving element in the window section of an enclosure incorporating light emitting and receiving elements. CONSTITUTION:A scattered luminous flux from a light emitting element 1 fitted in an enclosure 5 having dimensions of several mm is guided to a diffraction grating 32A formed on the external surface of a glass plate 3 through a collimator lens 31A. The grating 32a transmits and diffracts the luminous flux into a plurality of luminous fluxes and emits the luminous fluxes to a relatively moving transparent scale 20. A reflection type diffraction grating 21 is formed on the scale 20 as a measuring scale and returns the incident luminous fluxes after reflection, diffraction, and position modulation. The reflected luminous fluxes are condensed onto the external surface of the plate 3 after the fluxes are transmitted and diffracted through diffraction gratings 32B and 32C which are shifted in phase from each other and received by light receiving elements 4B and 4C. As a result, periodic signals A and B which are shifted in phase from each other by 90 deg. are obtained and, by processing the signals A and B, the relative displacement between the sensor and scale is detected.

Abstract: PROBLEM TO BE SOLVED: To easily secure the space of an abnormal position display section by setting the number of display digits of the abnormal position display section smaller than the number of digits of an abnormal place code, and displaying the abnormal position code by the prescribed digits in sequence. SOLUTION: When a controller 10 finds an abnormality, it displays an abnormal position code set in advance for each abnormal position on an abnormality display section 29. The number of display digits of the abnormality display section is set smaller than the number of digits of the abnormal place code, the abnormal position code is displayed by the prescribed digits in sequence, thus the abnormal position can be displayed with a display device having a less number of display digits. The space of the abnormality display section 29 is easily secured, and the cost of the abnormality display section 29 can be reduced. The abnormality display section 29 is constituted of a single seven- segment display device displaying an alphanumeric character of one digit, thus the part cost can be suppressed.

Title: Thermoplastic resin foam and its manufacture
Inventor: YODA KAORU
IPC: B29C48/38
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture the thermoplastic resin foam of a cell which has a fine surface appearance and an average microcell diameter and a uniform average cell density by causing a mixture of respectively specific amounts of thermoplastic resin and fluoroalkane ester of fatty carboxylic acid at a specific temperature to foam with an inert gas in a supercritical state as a foaming agent. SOLUTION: A resin composition consisting of 100pts.wt. of thermoplastic resin and 0.1-10 pts.wt. of fluoroalkane ester of fatty carboxylic acid is melted at 100-400 deg.C in an extruder. Further, 0.1-30 pts.wt. of inert gas in a supercritical state as a foaming agent are added for 100 pts.wt. of the thermoplastic resin composition to create a completely miscible state between the thermoplastic resin composition and the inert gas. Next, the temperature of the molten resin is reduced to 60-200 deg.C in the extruder while the pressure is maintained at a level higher than the critical pressure of the inert gas as the foaming agent. Thus it is possible to obtain a processing rate 1.2-2 times as much, compared to the case in which the thermoplastic resin alone is used, in a die heated higher than the glass transition temperature of the resin.
