Title: Hardness discriminating method for clamped body
Inventor: OOKA MASAHIRO
IPC: G01L5/16
Filed: 1988-12-12
Abstract: PURPOSE:To simplify a device by calculating the ratio of a combined force of the component forces in two horizontal directions and a component force in the vertical direction along a clamp surface, and discriminating the hardness of a clamped body in the manner of comparing the calculated value with the threshold. CONSTITUTION:The body 14 to be clamped is clamped between finger parts 11 and 12, and when a force applying to the upper/lower directions is expressed as F, an adding value T of the outputs in the horizontal direction, which is obtained by a shearing stress produced on the contact area, is shown as an equation I where, (i) is an integer of 1-n and (j) is the one of 1-n. So, when the hardness of the body to be discriminated is expressed as Hd2, the ratio of the combined force of the component forces in two horizontal directions and the component force in the vertical direction is calculated, and the hardness Hd2 of the clamped body can be discriminated by comparing the calculated value with the threshold. That is, the hardness Hd2 for the body can be obtained by the equation II. In this case, if the body 14 is hard although the force F is same, the contact area for the finger part 12 and a pressure sensor 10 is not so expanded and also the shearing stress is small. But, if the body is soft, the contact area for the finger part 11 and the pressure sensor 10 is going to expand then the shearing stress is made to be larger.

IPC: G01S17/931
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a distance measuring apparatus for measuring the distance from its own vehicle and the azimuth with respect to the vehicle of an obstacle existing in front of the vehicle in a short time. SOLUTION: Distance sensors 101 and 102 installed on both of the front ends of a vehicle 100 include respective light sources and light receiving elements, and alternately cast light beams 103 and 104 that are extended only on one side at time intervals of, e.g. 1 ms. The sensors measure independently the distances from an object 106 by receiving the reflected light from the object 106. In the overlapping region 105 of the light beams 103 and 104 that are extended only on one sides, the distance between the object 106 and the vehicle 100 and the azimuth to the vehicle 100 can be measured by trigonometrical survey setting the interval between the two distance sensors 101 and 102 as the base line.  The lengths of the beams 103 and 104 in the traveling direction are about 50 m, and the width of the overlapping region 105 perpendicular to the traveling direction is about 2 m which is a little larger than the width of the vehicle 100.

Title: Router processing equipment for manufacturing game machine
Inventor: TAKAHASHI HATSUMI
IPC: A63F7/02
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To collect cutting chips from router processing automatically and to improve productivity. SOLUTION: At router processing, when an opening is formed at a game board 9, the air blown up from air blowing means 21 generates negative pressure, and the negative pressure creates a flow of air that flows from the upward of the game board 9 to the opening of the game board 9 and to a trash disposal hole side of a table 8. This flow of air carries cutting chips 18 around the game board 9 to the inside of a dust collection housing 12 and a dust collector 17 collects it from the dust collection housing 12. The air blowing means 21 blows and reuses clean air which is filtered from the cutting chips collected in the duct collector 17, and it can eliminate an air blowing supplier like a compressor in addition to the absorbing power generator 16 and it simplifies the structure of the equipment.

Title: Paper feeder
Inventor: FUKUNAGA TAKEHITO
IPC: B65H1/26
Filed: 1987-12-11
Abstract: PURPOSE:To enable paper to be supplied in a condition that hand is detached from a tray by providing a reduction gear means which decelerates a rising speed of the tray rising being urged by an urging member. CONSTITUTION:In case of supplying paper, first opening a paper feed door 31, next by hand, a tray 18 is depressed against the urging force of a coil spring 19. Thus in a condition that the tray 18 is depressed, when the hand is detached from the tray 18, it tends to rapidly rise by the urging force of the coil spring 19, but because a damper gear 26 is connected to a drive shaft 24 through a gear 25, applying a rotary load acting decelerating a running speed of lift belts 20, 20, the tray slowly rises. Accordingly, even in a condition that the hand is separated from the tray 18, enabling the paper P to be loaded on the tray 18, with no necessity for retaining the tray by the hand as in the past, the workability can be improved.
