Title: Molding flask
Inventor: OKADA ISAO
IPC: B22C21/02
Filed: 1989-06-30
Abstract: PURPOSE:To lighten a molding flask in weight by providing the molding flask main body having height lower than that of molding sand and a projecting part projecting from the molding flask main body and detaining the molding sand with this projecting part. CONSTITUTION:At the time of making the mold, after laying the molding flask 1 and a raising flask 6 on a pattern base plate 9, the molding sand is charged into both flasks 1, 6. Successively, the molding sand is pressed with a pressing plate 7 having projecting stripes 8 to pack this into high density condition. By removing the raising flask 6 and the pattern base plate 9, the desired mold is obtd. and the molding sand projecting from upper face 3 of the main body is detained with the projecting part 4 to prevent mold crack. By this method, the molding flask can be lightened in weight and gas vent at the time of casting is quickly executed and mold deformation with the lapse of time is prevented.

Title: Load sensitive type proportional valve
Inventor: KUWABARA TOORU
IPC: B60T8/26
Filed: 1982-09-29
Abstract: PURPOSE:To make maximum braking force producible without locking rear wheels, by detecting both front and rear wheel load values, and operating a pressure reducing valve according to these rates, while feeding a rear wheel brake with more compressed air than that of a front wheel brake. CONSTITUTION:In braking, when a brake is applied, a brake valve opens whereby compressed air in a pneumatic tank is directly fed to a front wheel brake, while the compressed air enters a first valve chest 22 from an inlet 7, then further enters a second valve chest 27 by way of a passage 25 and is fed to a rear wheel brake. At this time, the compressed air introduced into the valve chest 27 forces a plunger 21 to the left against a force of a spring 17 as well as exciting force of a solenoid coil 16, opening a check valve 15, thus the pressure of the valve chest 27 is decompressed. The amount of left-handed displacement in the said plunger 21 varies with the electric current added to the solenoid coil 16 and this current is controlled according to the rate of rear wheel load to front wheel load.

Title: Method and device for controlling program of processor having single address space
Inventor: SAKAGAMI HIROSHI
IPC: G06F9/46
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To generate processes with memory succession in a single address space. SOLUTION: The hierarchies of the processes are constituted by permitting a master process to sequentially generate a slave process. Memory areas in the address space 10, which have the same storage protection keys, are allocated to the processes of the respective process hierarchies. An operating system allocates the memory area having the storage protection key lower by one hierarchy to the slave process in the same size as the memory area allocated to the master process in response to a request from the master process and copies the content of the memory area of the master process in the memory area of the slave process. The memory area reference of the master process, which is generated by the slave process during the execution of the program, is detected by a storage protection exception. Address information by which the memory area of the master process is referred to is converted into corresponding address information in the memory area of the slave process memory so as to refer again to the memory area.
