Title: Dual brake valve
Inventor: YANAGAWA ICHIROU
IPC: B60T15/04
Filed: 1978-06-06
Abstract: PURPOSE: To avoid overworking only one brake system on equalizing the braking pressures to respective shafts by extinguishing the pressure difference between the primary and secondary outputs almost completely in the dual brake valve.  
     CONSTITUTION: When the brake pedal 32 is depressed to descend the primary piston 27 in the dual brake valve 1, the secondary piston 28 is also dropped through the spring 64, the exhaust valve seats 33, 34 come in contact with the valve seats 38, 39 of the valve discs 25, 26 respectively. When the valve seat 38 is separated from the valve seat 40 by the said valve seat 33 successively, compressed air flows from the feed port 21 to the output pressure chamber 46 and output port 23, and enters the pressure chamber 49 through the air inlet 48. When the valve 66 is opened, the air flows to the pressure chamber 27 and output port 24. Thus the pressures in the chambers 49, 47 are equalized, the pressure difference between the primary and secondary outputs can be completely extinguished.

Title: Method and apparatus for foam molding
Inventor: HASHIGUCHI YOSHITAKA
IPC: B29K105/04
Filed: 1989-03-20
Abstract: PURPOSE:To obtain a molded body having favorable filling properties even when the molded-body is thin-walled one by a method wherein expandable beads are filled in a cavity under the condition that molds are brought into the state of cracking while being kept airtight and, after that, the molds are clamped and the beads are fusion-welded together by heating. CONSTITUTION:The apparatus concerned consists of a core mold 1 and a cavity mold 2. A cavity 3 is formed between both the molds 1 and 2. Side wall parts 1c and 2c, which forms the parts of the cavity 3, are designed to be longer than normal ones. At the same time, flanges 1a and 2a are provided around the parting face (p) between the core mold 1 and the cavity mold 2 so as to hermetically engage with each other by means of packings 1b and 2b. Even under the state of cracking, the molds can be kept in airtight state by the flanges 1a and 2a through the packings 1b and 2b. Under the condition that the molds are brought into the state of cracking while being kept airtight, expandable beads are filled in the cavity under pressure or vacuum and, after that, the molds are clamped and the beads are fusion-welded together by heating. Since the expandable beads are filled under the condition that the volume of the cavity is enlarged by the amount for cracking and, after that, the molds are clamped, poor filling is prevented from occurring even at the molding of a thin-walled molded item.

Title: Velocity control method
Inventor: SATO HIROSHI
IPC: G05D3/12
Filed: 1988-03-23
Abstract: PURPOSE:To obtain a moving locus with high accuracy by preventing oscillation from being generated in a servo mechanism even when large speed change is generated by increasing or decreasing change between speed at every section narrower than a separate section at the time of shifting from the separate section to the next separate section with different speed. CONSTITUTION:The amount of travel in the next sampling section is found from a remaining amount of travel and a remaining sampling period by using the speed vc in an interpolating small section and the speed vd in the next interpolating small section. Therefore, the speed designated in each interpolating small section differs remarkably from each other, and speed difference can be reduced sequentially. In such a way, it is possible to prevent the oscillation from being generated in a servo motor by eliminating the difference in the amount of travel supplied to the servo mechanism.
