Title: Control on oil pressure of excavator
Inventor: ASAOKA MASAHARU
IPC: E02F3/40
Filed: 1982-08-30
Abstract: PURPOSE:To permit smooth excavation by an excavator by a method in which when an excavator is in operation, a vibration signal is given to a proportional control valve provided to intermittently change the speeds of a cylinder. CONSTITUTION:When a solenoid valve 14 is in non-excited state, the valve 14 is held at the position as shown by Fig., and one pilot pathway 12 is led through a communication path 19 to a proportional control valve 15 and the other pilot pathway 13 is led to an tank 20. When the valve 14 is excited, the pilot pathway 13, on the contrary, is led to the proportional control valve 15 and the pilot pathway 12 is led to the tank 20. When a manual switch 47 is closed, the solenoid valve can be continuously switched only during the period when the switch 47 is closed. Thereafter, smooth excavation can be attained when the excavator of a bucket and the like is vibrated.

Title: Router device
Inventor: YAMASHITA YUHEI
IPC: H04L69/40
Filed: 1995-06-16
Abstract: PURPOSE: To facilitate the maintenance of a network system and to properly construct the system by making a router device containing a RIP(routine information protocol) monitor the signal put on a transmission line connected to the router device itself and then detect a disconnection fault and its recovery of the transmission line. CONSTITUTION: If a transmission line 2a connected to a router device 1 has a disconnection fault, etc., a transmission line disconnection detection part 4a detects this fault and notifies a RIP control part 6 of it. The part 6 suppresses a RIP execution part 7 to output a RIP. When the fault of the line 2a is recovered by repair, the part 4a also detects this recovery and notifies the part 6 of it. The part 6 sends a signal to the part 7 to restart output of the RIP as long as a recovery notification switch is turned on. The part 6, however, sends a signal to the part 7 to inhibit output of the RIP if the switch 8 is not turned on.

Title: Boronized fiber and its preparation
Inventor: HIROSE MINETAROU
IPC: C23C16/28
Filed: 1980-10-27
Abstract: PURPOSE: Boronized fibers, consisting of three layers of the remaining wire (filament), a boronized layer formed from diffused boron atoms and a layer of adhered fine boronic particles, and suitable for preparing a fiber-reinforced composite material by incorporating into a matrix material e.g., a plastic.  
     CONSTITUTION: The internal pressure of a vacuum tank 16 is reduced to about 100Pa, and a shutter 21 is opened to cool generated boron vapor by the repeated plural times of collisions with Ar atoms in Ar gas and adhere to one another by the mutual collision with the boron vapor. Thus, the boron vapor floats in the vacuum tank 16 and forms a fume while growing as particles. A part of a wire (filament) 17, e.g. titanium, hung from supporting rolls 3 in the vacuum tank 16 is enclosed with the atmosphere of the fume. The supporting rolls 3 are heated by the electric conduction through an electrode and the wire 17, the fine boronic particles collided with the surface of the wire 17 adhere thereto and diffuse the boron atoms in the surface of the wire 17. Thus, the aimed fibers consisting of the remaining wire 24, boronized layer 25 and layer 26 of the fine boronic particles are obtained.

That is, in the beginning, the fuel and air are fed at a minimum flow rate at which combustion can be sustained, and the feed rates are gradually increased. At extinction step, the combustion rate is gradually reduced by the sequence function of the controller 8 until it reaches the minimum rate, and then the combustion is stopped. That is, the extinction is done after the feed rates of fuel and air are gradually reduced to a minimum rate at which combustion can be sustained.
