Inventor: KAARUUHAINTSU SHIYUTORUKU
IPC: G01M17/02
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To hold a belt stably in a transversal-side position even when a transversal force is generated by a method wherein a tension roller is installed at the inside of a driving and running belt so as to be twisted horizontally around its vertical axial line and its, reaction force is given in a state that the tension of the belt is maintained. SOLUTION: A column 12 supports a tension roller 7 so as to be rockable with reference to a frame 2, one end is a spherical hinge coupling 13 so as to be coupled to a component which is guided and held by a guide 18 at a lower support table 10, and the other end is a spherical hinge coupling 14 so as to shaft-support the roller 7. A rod 17 moves the column 12 to the horizontal direction, it displaces spherical hinge couplings 16 on both sides of the roller 7 to opposite directions, the roller 7 is twisted and moved around a vertical axial line 9, and both ends of a shaft 11 are moved on an arc. The bias tension of a running and driving belt 5 relatively moves a component composed of a piston and of a cylinder to a direction at right angles to the table 10.  In this manner, the displacement from an ideal position of the center of the shaft 11 at the maximum steering angle of the roller 7 can be reduced so as to be negligible.

Title: Preparation of skinless foam sheet
Inventor: YOSHIDA HIROSHI
IPC: B29K27/06
Filed: 1983-12-23
Abstract: PURPOSE:To form a skinless foam sheet having various surface configuration and different in feeling, by providing a foam layer between base materials and, thereafter, mechanically tearing the part of said foam layer. CONSTITUTION:A composite body consisting of a base material 1, a base material 2 and a foam layer 3 is torn to form a skinless foam sheet A consisting of the base material 1 and a foam layer 4, and a skinless foam sheet B consisting of the base material 2 and a form layer 5. In each skinless foam sheet, the cell size of the foam layer 3 is controlled by appropriately selecting the composition of the foam layer 3 of the composite body or a foaming heating condition and, further, a tearing condition is controlled to enable the preparation of a sheet having various surface configurations. For example, when tearing is performed at a hightemp. directly after the foam layer 3 was formed, a sheet having a configuration, such that a fiber is embedded in the sheet, is obtained because a cell wall is cut in an extended state. In addition, when the foam 3 layer has a large cell, touch-feeling similar to artificial turf is developed and, when a small cell, back skin like finish can be performed.

Title: Optical communication equipment
Inventor: MAMINE TAKAYOSHI
IPC: H04B10/2507
Filed: 1986-10-13
Abstract: PURPOSE:To obtain a stable digital communication and to evade the degrading in the reliability and service life of a laser diode by using a laser diode whose optical output-current characteristic has a super linear characteristic area for a light emitting element. CONSTITUTION:As the light emitting element, a gain guide type semiconductor laser diode is constituted by using the laser diode whose optical output-current L-I characteristic curve shown by the full line curve 1 of the figure has the super linear characteristic area. This means that a current limited area is provided for that a current collectively flows within the oscillation area of an active layer. In this case, as the degree of light excitation increases, a dip in gain occurs in a gain distribution curve 3A. As a result, a virtually positive refraction factor distribution is generated in the middle of a refraction distribution curve 3B, accordingly, the light shifts to a wave-guided state from a non- wave-guided state, and thus the super linear characteristic area in which the optical output is increased in proportion to the aggregation of input current. Since the modulation is executed by using this area, the degrading of differential efficiency can be improved, therefore, the temperature rise is suppressed, as a result, the life and the reliability of the titled equipment can be improved.
