Title: Optical fiber connection part
Inventor: SOTODANI SHIGEO
IPC: G02B6/24
Filed: 1980-04-11
Abstract: PURPOSE:To improve mechanical strength and the efficiency of assembling work by using the composite reinforcing material of the same plastics as those of plastic covering and glass fibers or silica powder. CONSTITUTION:Composite material 5 of the same plastics as those of plastic coverings 4 of the parts of both ends to be connected and glass fibers or silica powder are covered on the connection part of optical fiber cores 1 removed of the coverings 4, and these are molded under heating in dies, whereby the solid type composite reinforcing material 50 is formed. It is equally well to use the composite materials 51, 52 in the form of a flat plate with grooves. If such composite reinforcing materials 51, 52 are used, the coefft. of thermal expansion is close to that of the optical fibers 1, the mechanical strength is high and the number of parts is less. Since the connection part is formed by the molding under heating, workability and economy are superior.

Filed: 1986-03-07
Abstract: PURPOSE:To give disturbance to a code rule at an optional transmission information location by applying coding that either of two kinds modes is assigned to a code mode bit when transmission information is the same mode as the transmission information of one preceding bit and the other mode is assigned when different. CONSTITUTION:When a violation input 50 is at '1' and status information 5g is at '1', that is, consecutive 2-bit of transmission information 51 is different from the code, a gate 5a is set and the code of the mode 0 are outputted.

Title: Optically functional film and its manufacture
Inventor: TSUCHIYA MITSURU
IPC: G02B5/26
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To obtain, by an application method, a functional film having high function and high quality wherein a film uniformity at least equal to a thin film formed by a gas phase method in uniformity of the film is provided by a method wherein the number of particles having a specific size or larger in the film is made a specific number or under. SOLUTION: Metal oxide sol is applied to a surface of a transparent resin base material by an application method, which is treated with electron irradiation. Thereby, a metal oxide gel film is formed. For example, the number of times of electron beam irradiation is 2 to 50 times, and its total amount is 50 to 500 Mrad. An optically functional film formed thus has a required function according to an application mateiral, the film is uniformized by irradiation with the electron beam, and though the particle is large, the number of them becomes very small. When the number of particles in the film having 10nm or larger particle size becomes mean 1000 particles or under per 10μm×10μm film area, the same film uniformity as that of a thin film obtained by a gas phase method is obtained.  A large particle disappears by raising the number of times for irradiation with electron beam and/or total does.

Title: Communication system with error correction and receiving device
Inventor: FURUYA YUKITSUNA
IPC: H04B1/713
Filed: 1982-03-26
Abstract: PURPOSE:To enable simultaneous communications for many stations, by supplying the signal of N bits to an M series generator at an N stage, transmtting the output of  the generator with popping of frequency to give adverse dispersion to the output at  the receiving side and deciding the output through a matching filter. CONSTITUTION:An information signal supplied to a terminal 100' is stored in a shift  register at an N stage and then supplied as the initial value of an M series generator  16 at an N stage. The generator 16 produces M series equivalent to a period while the  next N-bit informaton is stored in a register an adds 30' the M series to the diffusion  code given from a diffusion code generator 10' to transmit them with popping of the  oscillating frequency of a frequency synthesizer 20'. The receiving side multiplies 40'  the transmitted signal by the carrier wave given from a synthesizer 21' and popped  with frequency by the diffusion code given from a diffusion code generator 11' and  performs the adverse dispersion. The multiplied signal is made to pass through a  matching filter group 70 matched with a pattern of M series after wave detection 50'. Therefore the maximum value emerges in a filter corresponding to a transmission pattern. Thus the transmitted signal can be decoded by detecting the position of a filter exceeding the threshold value through a deciding circuit 80.

Title: Gasification burner combustion controlling device for grain particles dryer
Inventor: HARUNA MITSUAKI
IPC: F23N5/12
Filed: 1984-03-14
Abstract: PURPOSE:To reduce a rate of occurrence of interruption during an operation as much as possible and improve an efficiency of drying operation by a method wherein a flame sensing means is arranged and a drying operation is continued even if a light of the burner is diminished in the midway of the operation and then a reignition is automatically performed. CONSTITUTION:When a flame of a burner B is diminished in the midway of the operation, the diminished condition of the flame is sensed by a flame sensor FS and a flame sensing signal is changed over from its ''ON'' condition to its ''OFF'' condition showing ''NO FLAME'', data of ignition stroke stored in advance in a memory part 28b by a control and calculator part 28a of CPU (central processing unit) 28, a reignition signal is outputted from a second output port and then an ignition heater 23 is energized. As a result, for example, in case that a cause of diminishing flame is due to a mixing of bubbles in the fuel or due to an instantaneous shut-down of electricity of a duration of 0.5sec or so, the system is recovered already to such a condition as a rapid ignition can be performed without performing any repair at all, so that the burner B is ignited again with an ignition heater 23 and a drying operation is continued.

Title: Cable treatment apparatus
Inventor: NOGUCHI TADASHI
IPC: H05G1/02
Filed: 1990-02-27
Abstract: PURPOSE:To treat the extension and contraction of a cable by concentrically providing guide rollers to the periphery of a rotary mechanism in a freely movable manner and branching a cable in two different directions along the outer peripheries thereof to draw out the same and always moving the guide rollers in the same direction when the rotary mechanism is rotated. CONSTITUTION:Both cables 15, 16 are wound around guide rollers 9a, 9b in mutually different directions and, since the downward cable 15 is moved in the same direction along with a squeezing device 3 the moment the squeezing device 3 is rotated in an H-direction, the guide rollers 9a, 9b becomes movable in an I-direction and, therefore, the upward cable 16 is taken up by the guide rollers 9a, 9b to be prevented from slackening. Since the cables 15, 16 are taken up as they are without being diveded into core wires, the extension and contraction treatment of the cables can be performed by a reduced number of parts. Since the cables 15, 16 branched in two directions are merely hooked with the guide rollers 9a, 9b without being taken up thereby so as to be changed in their advance directions, it is unnecessary to extend the lengths of the cables.
