Filed: 1980-10-01
Abstract: PURPOSE: To separate and recover harmful heavy metals easily, by bringing an aqueous solution containing lithium and arsenic into contact with insoluble amorphous hydrous tin oxide or crystalline tin hydroxide, adsorbing the lithium and arsenic, and eluting both separately.  
     CONSTITUTION: An underground brine or geothermal hot water is used as an aqueous solution containing lithium and arsenic. The aqueous solution is previously adjusted to a pH of about 5W10, and amorphous hydrous tin (IV) oxide or crystalline tin (IV) hydroxide in an amount of about 0.1W5wt% is brought into contact with the adjusted aqueous solution to adsorb the lithium and arsenic. After adsorbing the lithium and arsenic fully, the solid adsorbent is separated from the solution. The separated adsorbent is then brought into contact with a dilute aqueous solution of an acid having a pH ≤5 to dissolve the lithium first. The adsorbent is then washed with water and then brought into contact with an alkali solution having a pH ≥10 to elute the arsenic.

Title: Identification system
Inventor: NISHIMURA TAKASHI
IPC: H04B5/02
Filed: 1995-05-12
Abstract: PURPOSE: To prevent the writing of error data without adding a specific function to an ID unit by providing the ID unit with an inherent number area for storing an inherent number. CONSTITUTION: The ID unit 3 includes a memory 1 for storing data and a data transmission means 2 for transmitting data read out of the memory 1. An ID number inherent in the ID unit 3 is stored in the memory 1. In a write/ read control unit 5, a data reading means 6 reads out data indicating the ID number stored in the memory 1 and an ID number storing means 7 stores the ID number. In the case of transmitting a command to the ID unit 3 after executing necessary processing, the ID number is read out again and compared with the stored ID number. Only at the time of coincidence between both the ID numbers, a writing command is transmitted. Consequently the writing of error data because of the substitution of the ID unit 3 can be prevented.

Title: Inter-process communication system using i/o port access
Inventor: BABA SHINICHI
IPC: G06F9/46
Filed: 1989-05-30
Abstract: PURPOSE:To attain the inter-process communication without calling out a complicated operating system OS by setting a mechanism into an OS to replace the I/O instruction of a process with the inter-process communication via a computer having an I/O instruction monitor mechanism. CONSTITUTION:When data are sent to a process b from a process a, an instruction e is first carried out and the process control is shifted to the OS of the process b via an I/O instruction monitor mechanism of a computer. Then the port number and the data to be transmitted via the process a are checked. This checked data is temporarily stored in a memory d and the control is sent back to the process a. Thus a transmitting process a is used together with a receiving process b, an I/O data control processor contained in the OS, and an I/O data holding memory d. Then the I/O instructions produced by both processes a and b are replaced with the inter-process communication. Thus the communication is carried out among plural processes. As a result, an inter-process communication system is attained in an extremely simple method.

Title: Casting method and device for pulling out core used in this method
Inventor: OKADA MASAMICHI
IPC: B22D29/00
Filed: 1994-06-21
Abstract: PURPOSE:To eliminate the need of a special process in a casting method by executing the pulling-out of a core in a trimming process, at the time of casting a product by press-charging molten metal into a cavity inserted with the core at high pressure. CONSTITUTION:The core (n) maintains a prescribed strength during a time since the molten metal is press-charged into the cavity until the part of the molten metal in contact with the core is solidified (characteristic of the molten metal A), i.e., during a time of T1, and even if the high pressure of the molten metal is applied to the core (n), the core is not deformed to such an extent that shape precision becomes lower than that required for the product X (characteristic of the core G1). Further, the average strength of the core (n) is lowered by the heat of the molten metal during the lapse of a time of T2 after the molten metal is solidified at the part in contact with the core (n) (after the lapse of a time of T1), the plastic deformation of the core is generated to such an extent that the core (n) can pass through an under-cut part of the product X and yet the mutual coupling force, by which one end can be pulled out by pulling out the other end, is imparted. Therefore, the core can satisfactorily be pulled out of the product by giving the pulling force to the core at the suitable timing during th lapse of a time of T2 after the lapse of a time of T1.
