Title: Output control method for gas shielded arc welding power source
Inventor: AOYAMA MASAHIRO
IPC: B23K9/06
Filed: 1988-05-24
Abstract: PURPOSE:To reduce the occurrence of spatters by holding a welding current at a high level during an arc period of time and decreasing it gradually from the high level during the time till a short-circuit period of time and superimposing a high-frequency pulse current thereon to prevent a droplet from being pushed up. CONSTITUTION:During the short-circuit period of time, since the welding current is increased to the high level after being held at a low level, the droplet in the short-circuited state is made in a spray shape and transferred smoothly to base metal to be welded. Further, during the arc period of time, the welding current is held at the high level and then, decreased gradually from the high level during the time till the next short-circuit period of time and the high-frequency pulse current is superimposed on the welding current, hence the droplet of the tip of a consumable electrode is prevented from being pushed up by the arc force during the arc period of time and the quantity of occurrence of the spatters is reduced and the incomplete penetration of the base metal to be welded is not caused and a fine weld bead is formed.

IPC: B28C9/04
Filed: 1991-03-13
Abstract: PURPOSE:To obtain the required concrete mixing temperature by adjusting the material temperature of the concrete by using a vehicle, on which warm water, cool water and an ice making apparatus are mounted. CONSTITUTION:Refrigerant is compressed with a refrigerator 1, and the high- pressure gas is obtained. The high-pressure gas is cooled with a condenser 3, and the high-pressure liquid is obtained. When the high-pressure gas passes through an expansion valve, the low-temperature, low-pressure gas is obtained. The gas enters a chiller 4, and heat exchange with water is performed. As a result, the water is cooled, and the cold water is obtained and drained. The low-pressure gas is compressed in the refrigerator 1 again, and the cold water is manufactured in the similar process. Therefore, a vehicle, on which a mixing apparatus is mounted, is used and the temperature of the material is adjusted before not only the cold water but also the warm water or ice are mixed into the concrete. Thus, the concrete is manufactured. In this way, movement is freely performed at the required time through the year, and the temperature suitable for the concrete can be adjusted.

Title: Radar equipment
Inventor: TAMAMA TETSUO
IPC: G01S13/46
Filed: 1985-06-12
Abstract: PURPOSE:To shorten a scanning time by controlling a scan in an elevation direction so that the number of times of scanning is proportional to costhetaE when an elevation is thetaE. CONSTITUTION:The part encircled with arcs AB, AP, and BP of a large circle in figure (a) is expanded as shown in figure (b). In this figure, there is no gap between beams because of a specific beam shape and center point positions of respective beams are determined so that there is no unnecessary overlap. Consequently, the number of center point positions is nearly proportional to costhetaE (thetaE: elevation). Therefore, when a scan is made so that the number of times of scanning in the elevation direction within a specific azimuth range is nearly proportional to costhetaE, any part in a specific three-dimensional space is scanned almost uniformly and the unnecessary overlap of the scanning beams is eliminated to shorten the scanning time.

Title: Starting time fuel injection controller for internal combustion engine
Inventor: ICHINOSE HIROKI
IPC: F02D41/34
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To surely supply fuel to each cylinder at the time of starting an internal combustion engine so as to improve the ignition performance of each cylinder by causing each cylinder to perform intake asynchronous injection by a specified number of times at the starting time of the internal combustion engine and then intake synchronous injection in synchronization with the intake process of each cylinder. SOLUTION: During the running of a four-cylinder internal combustion engine 1, if the starting state of the internal combustion engine 1 is determined, an ECU 15 executes a starting time fuel injection amount control routine and a starting time injection time control routine and then calculates the fuel injection amount and time of each cylinder. In other words, a total number of times of fuel injection from a starting time is stored in a RAM, and one increment is made for each fuel injection. Also, determination is made as to whether or not a total number of times of fuel injection after increment is lower than the cylinder number of the internal combustion engine 12 for each increment.  If YES, a fuel injection time is set to be asynchronous with the intake process of each cylinder and, when a total number of times of fuel injection exceeds the cylinder number, a fuel injection time is set to be synchronous with the intake process of each cylinder.
