Abstract: PURPOSE:To lay easily a net on track bed by bonding the net to crushed stone on the track bed with asphalt when the net for preventing the crushed stone on the track bed from scattering is laid on the track provided with the track bed formed of layered crushed stone and a rail way laid on the track bed. CONSTITUTION:Side nets 5 and central net 7 are laid on the surface of bed of a track 1 having the track bed. Then, the outer side adhesion part 11 of the side net 5 and a protrusion inner side adhesion part 13 along the border of a tie 3 and rail 2 are bonded to the track bed with asphalt. Also, the peripheral adhesion part 15 of the middle part net 7 is bonded with asphalt.

Title: Transmission system and communication method therefor
Inventor: OOKURA TAKANORI
IPC: H04L12/28
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To improve the communication efficiency of a transmission system through elimination of a fault frame with the possibility of circulating or wondering on a transmission path by the data destruction or the like of the reception destination and transmission origin of a communication frame, due to noise or the like on the transmission path in the node of a prescribed number order. SOLUTION: Assume that a node D of the reception destination of transmission data 80 has gone down by a fault. Since a system transmission path is in constitution for bypassing the down node, the data 80 which cannot be received in the node D are infinitely circulated on the transmission path 1 in the state. Then, the transmission data 80 which bypass the node D are successively passed through the respective nodes inside a loop by repetition, while reducing the value NC of a circulating processing identifier 83 one by one and reach the node N. The circulating data processing part of the node N subtracts '1' from the value of the circulating processing identifier 83, and when the value becomes '0', stops the repetition of the reception data and abandons and eliminates them.

Title: Method for growing epitaxial thin film crystal
Inventor: NARISAWA TADASHI
IPC: H01L21/20
Filed: 1987-07-23
Abstract: PURPOSE:To make it possible to accomplish epitaxial growth having a large difference in grating constant or a large difference in thermal expansion coefficient at low defect density by a method wherein the substrate surface to be used for epitaxial growth is processed in such a manner that it has a special structure including recesses and projections. CONSTITUTION:A crystal thin film 2, having the grating constant different from that of a crystal substrate, is epitaxially grown on the crystal substrate 1. At that time, a processing work is conducted on the surface of the substrate 1 to form the structure such as recesses and projections and the like. As a result, the thin film 2 covers an aperture part and it becomes a continuous film before it reaches the critical value. As the thin film 2 on the aperture part is not contacted to the crystal of the substrate 1, it is not subjected to the effect of the crystal field of the substrate, and the crystal is epitaxially grown in lateral direction. Accordingly, the distortion caused by the difference in the grating constant can be alleviated by the elastic bending of the wall between the holes of the substrate 1 or by the bending of the thin film 2 in vertical direction. As a result, the epitaxial growth having a large grating constant difference or the difference in the thermal expansion coefficient can be conducted in low defect density.

IPC: G06V30/18
Filed: 1980-12-26
Abstract: PURPOSE:To discriminate the shape of a handwritten character by comparing the contents of a handwriting input register with those of a memory circuit for the feature part pattern of a character shape successively. CONSTITUTION:Sensor terminals 11-19 are grounded through a case 1 by being touched with a finger, etc., and those sensor terminals are touched with the finger in the order of a character shape to be drawn, so the order of grounding the sensor terminals is detected to discriminate the drawn character shape. There are 28 inputs 41-48 of sides obtained by connecting adjacent point inputs with straight lines, and 26 alphabets, numbers, etc., are expressed easily. Feature parts regarding capital letters of alphabets and numbers are shown by solid lines in the figure, and have combinations that other characters do not have. As a character-shape pattern registered in a memory circuit, only those feature parts are used, and a handwriting input is compared with only the feature parts, thereby decreasing memory capacity and shortening comparison time.

Title: Piston rod guide mechanism for car shock absorber
Inventor: KAWAKAMI SHINYA
IPC: B60G17/015
Filed: 1981-11-17
Abstract: PURPOSE:To aim at promotion of reducing friction as well as to obviate a tilting motion and one-sided contact of a rod in order to stabilize damping force, by installing a ball slide bearing in at least either rod guide or piston. CONSTITUTION:Since ball slide bearings 15 and 20 are used in both a rod guide 14 and a piston 19, the frictional resistance at the sliding of a piston rod 13 can be decreased. In addition, clearances between the piston rod 13 and the rod guide 14 as well as between the piston 19 and a cylinder 11 can be set to be small. Therefore, even when a load in a tilting direction is imposed on the piston rod 13, the tilting quantity is lessened, thereby obviating the one-sides contact so that damping force can be stabilized.

Abstract: PURPOSE:To improve properties of design and assemblage and provide the circulator, prominent in performance also, by a method wherein the main body of circulator is constituted of a front section, a rear case holding fans, a switch case encasing electric parts and a rear cover holding the switch case. CONSTITUTION:The main body 1 is separated into the front section 2, the rear case 3, the switch case 3 and the rear cover from functional aspect.

Centrifugal fans 6 are covered by a front case 2, therefore, the constitution of the circulator is prominent in design also. The upper part of a filter is constituted of a screen while the lower part thereof is constituted of slit-like holes, therefore, the suction stream of air shows a frequency characteristic having no turbulence such as pulsation or the like. Further, indoor convection is effected smoothly from the opening of the circulator during a time from ignition to the point of ON of a stove, therefore, the practicality of the circulator is very high.

Title: Cassette positioning device
Inventor: TAKITA KOHEI
IPC: G11B15/675
Filed: 1989-07-19
Abstract: PURPOSE:To ensure the positioning and holding of a cassette at the time of mounting it by arranging a supporting shaft supporting a positioning pin and a height-regulating pin for a small cassette almost in parallel with respect to a chassis. CONSTITUTION:The positioning pin 13 and a standard cassette detection member 15 are integrally fixed to the supporting shaft 16 which is freely and rotatably supported on the chassis 10. At the time of mounting a C cassette 1, a gutter in the direction of the supporting shaft of the pin 13 is eliminated by allowing a pressure spring 31 to press the pin 13. The pressing force of the cassette given to the pin 13 is in a direction pressing the pin to a stopper member 17 and therefore the position of the pin 13 can securely be held without coming unstable owing to the mounting of the cassette. Since the detection member 15 is pressed down anticlockwise by the cassette 2 at the time of mounting a standard cassette 2, the pin 13 falls together therewith. Consequently, collision with the pin 13 is prevented.
