Title: Communication network
Inventor: JIYON ERISU DOREEKU JIYUNIA
IPC: H04L12/18
Filed: 1993-06-07
Abstract: PURPOSE: To provide a management means for a plurality of message distributed trees of a message communication user group. CONSTITUTION: Each node of a multi-node communication system has an operating process to generate distribution trees, by which efficient multiplex arrangement and band width reservation tasks are conducted as a set manager for a specific set of nodes and users. The count of active users in a node is given in response to an index set, when a tree leader makes a tree. Each set manager in a specific node monitors changes in master-slave relation of trees and a link fault and informs the necessity of the tree leader to each tree related to the case of occurrence of a link fault by direct communication between the set manager and the tree leader, without intervention of other elements of the system or the occurrence of a change in the number of users.

IPC: B25C1/04
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a nail driver in which tar in a nose portion can be removed during a nail driving operation. SOLUTION: A pneumatic nail driver is arranged such that a driver 4 as well as a striking piston 3 is driven by high pressure compressed air supplied into a striking cylinder and that a nail 8 supplied into a nose portion 6 is driven out by this driver 4. The outside diameter of a base 4b of the driver 4 which fits in a driver guide hole 5 when the driver 4 arrives at a bottom dead center is made to be substantially equal to the inside diameter of the driver guide hole 5, and the outside diameter of a distal end 4a is formed smaller than the inside diameter of the outside diameter of the nose portion 6, whereby the driver 4 is guided loosely by the driver guide hole 5 in such a manner that the driver swings during a striking operation and the distal end 4a of the driver so swinging wipes off tar adhering to the inner wall of the nose portion 6.

Title: Data recorder and synchronous recording system
Inventor: SUZUKI YOSHIYA
IPC: G01D9/00
Filed: 1994-05-13
Abstract: PURPOSE:To provide a light-weight and compact data recorder. CONSTITUTION:The recorder is constituted of a battery, a signal-adjusting part for processing input signals from a sensor, a recording part for preserving processed signals as data, and a control part having a function to automatically start recording of data, all incorporated in one unit. Since the recorder is connected and wired immediately beside each sensor, a wiring length is considerably shortened. Since necessary data are automatically collected as a train passes, it is enough for an operator to wait at a safe place far from a measuring point after connecting the data recorder to the sensor. Accordingly, a preparatory work for the measurement is simplified, thus improving a working efficiency and a safety.

IPC: E01C11/26
Filed: 1993-05-13
Abstract: PURPOSE:To cut down the cost of construction and to reduce power consumption, by a method wherein a sheet on which surface far infrared ray-emitting granular materials are stuck and on which bottom a heating member is stuck, is spread in a road bed, and snow is allowed to melt by applying an electric current to the heating member. CONSTITUTION:Far infrared ray-emitting granular materials 3 comprising natural stones, ceramics and so on are stuck on the surface side of an adhesive sheet 2 such as a butyl sheet. After that, an electric wire 4 as a heating member is stuck on the bottom side of the sheet 2. When a road is paved, the title sheet 1 is spread before the road is paved with asphalt. After terminals 6 of the electric wire 4 are connected to each other with crimp contacts or the like, asphalt pavement is constructed on the sheet 1. In this way, since far infrared rays are emitted, the effect of emitting heat can be increased, and since a power charge can be cut down and its work can simply constructed, the cost of construction can be cut down, and a period of a roadblock can be shortened by shortening a construction period.

Title: Production of toner
Inventor: KASAI HIDEAKI
IPC: G03G9/087
Filed: 1996-05-30
Abstract: PURPOSE: To easily produce a low-cost high-quality toner in a very high yield by directly dyeing synthetic resin particles with a water-soluble dye in a dyeing medium under specified conditions. CONSTITUTION: Synthetic resin particles having a prescribed particle diameter or average particle diameter are dyed with a water-soluble dye under stirring in a dyeing medium made of water heated to a temp. between the softening point of the resin particles and the softening point +40 deg.C in the presence of fine anhydrous silica powder. The weight ratio of the water to the resin particles is >=5. The dyed resin particles are dehydrated and dried. When the temp. of the medium is below the softening point of the resin particles, it is difficult to dye the resin particles to the required color density or practical dyeing is not carried out because a remarkably long time is required. When the temp. of the medium is above the softening point +40 deg.C, the resin particles fuse even by dyeing under vigorous stirring to form an aggregate unfavorable for a toner.
