IPC: C21D9/08
Filed: 1989-11-10
Abstract: PURPOSE:To prevent the layer with change in quality from generating inside the hole by heating by preliminarily injecting the inert gas into the blank material having a center hole, heating this in the state of completely closed and executing upsetting. CONSTITUTION:Before upsetting work, the Ar-gas 4 is injected into the center hole 2 and the air is substituted completely with the Ar-gas. Next, the cap 5 is inserted into the opening of the center hole 2, and the cap is subjected to full-circled welding 6 against the blank material 1 and the Ar-gas is enclosed. Next, after the blank material 1 is heated, worked with upsetting and compressed in the axis center direction, then the heat treatment is executed. After normalizing and/or annealing, the upper part of the blank material is cut at the cutting line 7 with the cap 5 fitted as it is. Therefore, the upsetting work is executed regardless of the heating temperature and the change in quality by heat inside of the hole is prevented.

Title: Anticorrosive method
Inventor: MORIOKA KOJI
IPC: F22B37/00
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To eliminate adverse influence on a human body with enhanced anticorrosive effect, to suppress a material cost and execution cost required for piping by charging inert gas in a hot well tank provided at a steam condensate return tube. SOLUTION: First, a steam condensate return tube B is filled with the atmosphere to contain a large quantity of oxygen. At the time of trial operating an air conditioner facility, a valve provided at a suitable position of the tube B is opened, and inert gas is supplied from an inert gas supply unit 6 to a hot well tank 4. The inert gas is introduced into the tube B via the tank 4. The atmosphere in the tube B is exhausted out of the tube B from the valve, the tube B is filled with the inert gas to eliminate oxygen. After the trial operation, the valve is closed, and an air conditioner facility is operated. At the time of operating the facility, no oxygen is supplied to the tube B. Thus, since it is always held in no oxygen state, corrosion of the tube B is suppressed to small amount. Accordingly, no adverse influence is imposed on a human body.

In this way, a current I flowing through a circuit comprising the transistor Q1 , can be made roughly equal with a current I3 which flows through a current containing the transistor Q3 . Here, if the value of the load resistor R1 is made equal with that of the load resistor R4 , a voltage V1 in both ends of the load resistor R1 becomes roughly equal with a voltage V2 in both the ends of the load resistor R4 .  As a result, a constant voltage BBG with the GND as a reference can be outputted as a constant voltage with the power supply VCC as a reference, and an output voltage with the power supply VCC can be made with a reference which is hardly affected by the noise, EMI or the like.

Filed: 1994-11-28
Abstract: PURPOSE:To make possible accurate, automated range measurements corresponding to vehicle velocity by varying the gain of a reflected pulse signal reception means according to the vehicle velocity. CONSTITUTION:Pulse signals are periodically transmitted by a pulse signal transmission means 5a to the outside only a predetermined number of times, and signals coming from the direction from which the pulse signals are reflected back from a target are continuously received by a reception means and binarized, and the binarized signals are added together for a predetermined number of times of transmission, at each of plural sampling points of different elapsed times from the signal transmission timing of the pulse signal transmission means 5a.

Title: High-pressure fuel injection device
Inventor: YOSHIDA TAKEO
IPC: F02M51/06
Filed: 1989-11-09
Abstract: PURPOSE:To enhance the accuracy of controlling injection of a high-pressure fuel injection device by forming a stepped portion in at least either one of a coin holder for storing an injection controlling solenoid coil main body, and the opposite face of the armature of a switching valve body, and providing between opposite faces a space by which to break a magnetic circuit at the adsorption of the armature. CONSTITUTION:Concerning movement of a switching valve body 15 to close a small hole 3c, a curve representing a residual magnetic force after stopping of a driving current is indicated by the broken line when an armature 15b is adsorbed to a coin holder 13 with no space between them. When a space A is secured as the armature is adsorbed, a curve representing magnetism is indicated by the continuous line because the magnetic resistance of the space is large. When addition of the residual magnetic force and the adsorbing force of the coil holder 13 and the armature 15b to each other is less than the pressing force F of a pressing spring, the switching valve body 15 is lowered but, because of a small area of adsorption, the adsorbing force is reduced to f1 which is smaller than usual, and when a short period of time elapses after stopping of the driving currrent actuation of the high-pressure fuel injection device is started; which should secure good responsibility and high accuracy of controlling injection of the device.
