Inventor: WATANABE KAZUO
IPC: B29D28/00
Filed: 1989-12-29
Abstract: PURPOSE:To efficiently prepare a reticulated polymer sheet (geogrid) having high dimensional accuracy and an arbitrary dimension by a method wherein a large number of holes are punched in a polymer sheet in the lateral direction thereof by punches and tension is applied to the polymer sheet in its longitudinal direction in such a state that the punches pierce the polymer sheet and, subsequently, the punched sheet is stretched in its lateral direction. CONSTITUTION:A large number of holes are punched in the material 7 heated to definite temp. by a material heater 1 by a punching apparatus 2 having a large number of punches and tension is applied to the polymer sheet in its longitudinal direction in such a state that the punches pierce the material 7 by a tensioning apparatus 3 to stretch the polymer sheet so as to form grids. Subsequently, when the material is sent into a tentering apparatus 6, rod-shaped bodies 11 are inserted in the holes of the material at the ends parts thereof in the longitudinal direction and an endless track 9 is driven in the longitudinal direction by a drive apparatus 8. The lower end parts of the rod-shaped bodies 11 are fitted in the grooves bored in a guide apparatus 12 and the rod-shaped bodies 11 are displaced in the lateral direction of the material with the movement of the rod-shaped bodies 11 in the longitudinal direction of the material to stretch the material in its lateral direction.

Title: Articulatio coxae pulling device
Inventor: KAWABE YOSHIHIRO
IPC: A61F5/042
Filed: 1989-12-29
Abstract: PURPOSE:To prevent the slip-off in pulling and permit the easy demounting by tightening a pair of pressing pieces applied on the over-knee part of a femur part by the pulling of a pulling string. CONSTITUTION:An articulatio coxal pulling device is constituted of a pulling string 14 and pressing pieces having a pair of insertion metal fittings 15 and 16 and a pair of stop metal fittings 17 and 18. When the pulling string 14 part of a loop which is constituted of the pulling string 14 and one pressing piece 6 is pulled, the pulling string 14 set between one insertion metal fitting 15 of the pressing piece 6 and the stop metal fitting 17 is made short, and since the part is laying-fitted with other pressing piece 7, the distance between both the pressing pieces 6 and 7 is contracted. Similarly, the pulling string between the other insertion metal fitting 16 of one pressing piece 6 and the stop metal fitting 18 is shortened by pulling, and the distance between both the pressing pieces 6 and 7 is contracted. Since a pair of pressing pieces 6 and 7 tightens the over-knee part of a femur part, the shift of the installation fitting from the over-knee part is prevented. Further, since also the tightening force is weakened when the pulling force is weakened, demounting is made simple.

Filed: 1992-12-24
Abstract: PURPOSE:To provide a carrier device which is capable of laying out a sample at a specified position definitely in spite of a sample deviation in a carrier process of the sample and the vibration of the carrier device. CONSTITUTION:A carrier device is provided with four pins 1a, 1b, 1c and 1d which are formed in the shape of a triangular post in the outer peripheral part on the top. The pins 1a, 1b, 1c and 1d are projected from holes 30b bored all over a loading mount from an outer edge of a pocket 30 which takes in a sample S. The tops of these pins 1a, 1b, 1c and 1d are cut off about their slanting areas 2a and 2b directed at the central part while flattened areas, such as 3a and 3b are formed directed at the central part from the lower end of the slanting areas 2a and 2b or the like. A sufficiently wider space is provided between the two pins 1b and 1c, which are opposed to the direction in which the sample is brought in. The deviations produced in this carrier process are guided to the flattened areas 3a and 3b along the slanting areas with which the sample S comes in contact so that they may be eliminated. In addition, the slanting areas 2a and 2d serve to restrict the horizontal movement of the sample S.

Title: Control method for unmanned travel vehicle
Inventor: SOEJIMA NOBUHIKO
IPC: A47L11/00
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To carry on a travel by evading an obstacle and reversing the unmanned travel vehicle at the time of its reversing operation. SOLUTION: This method moves the main body forward by a specific distance after turning the main body by 90 deg. in front of the front wall surface of a specific area, and then reverses it again by 90 deg. so that the main body travels reciprocally. At the time of this reversing operation, a main control part 10 temporarily stops turning the main body by 90 deg. when judging that an obstacle detected by an ultrasonic sensor of an ultrasonic sensor part 12 on the flank of the main body is in a specific range from the main body, and then makes the main body travel forward by a set distance if the obstacle is still within the specific range even a specific time later. The main body is put away from the obstacle by traveling by this set distance and is reversed by the remaining angle.

IPC: H01L21/302
Filed: 1993-12-24
Abstract: PURPOSE: To reduce contamination by sputtering, and to improve inductive coupling with plasma by shunting a capacitive electric field generated at high potential on an adjacent spiral-shaped or helical-coil to grounding. CONSTITUTION: A flat plasma 110 is generated by the flat shape of coils 116, and a workpiece 106 is processed uniformly. Consequently, the face, on which the coils 116 are placed, is positioned in parallel with an inductive window 122 and a conductive shield 124. The conductive shield 124 is grounded by direct connection with a matchbox 114, and the matchbox 114 is connected to a process-chamber 102. The conductive shield 124 induces a capacitive electric field generated by the coils 116 towards the direction of the matching box 114, separated from the inductive window 122 and grounded during the operation of a device 100. An interference by the capacitive electric field with inductive coupling among the coils 116 and plasma 110 is reduced by grounding the capacitive electric field.

Title: Waving brazing filler metal and manufacture thereof
Inventor: KOGA AKIMITSU
IPC: B23K35/14
Filed: 1991-12-27
Abstract: PURPOSE:To reduce the developing ratio of voids at the time of melting by using a waving brazing filler metal having width within the width of a joining surface and continuous waving shape. CONSTITUTION:The waving brazing filler metal 3 having the waving width B within the width A of the joining surface 2 and the continuous waving shape is put on the joining surface 2 and joined with the objective material. Even at the time of brazing, as the brazing filler metal has the waving shape, this metal is stably put in between the joining surfaces. As the line having small contacting part to the joining surface becomes the starting point and spreads, the developing ratio of the voids at the time of melting is little and the air- tightness is good. As the manufacture of the waving brazing filler metal 3 is worked by using a forming machine, the product yield is high.
