Title: Virtual memory system
Inventor: NINOMIYA YUKIO
IPC: G06F12/10
Filed: 1986-02-04
Abstract: PURPOSE:To eliminate the need to set previously the capacity of a virtual memory area at the too large value by allocating the page contents to be transferred to the virtual memory area at every time of the transfer of page contents is required to the virtual memory area provided to a memory means from a memory and then transferring the page contents. CONSTITUTION:A processing request is generated for remaining page contents of a program which is not stored in a main memory 5 according to the progress of the processing carried out in response to a program stored in the memory 5. Then it is decided whether the prescribed page of a program Pa to be transferred to the memory 5 is stored in a virtual memory area 4 or not with reference to an area Va1 corresponding to an area Ma1. If the prescribed page contents are stored in the area 4, the page contents are transferred to the page area S1 of the memory 5 from the area 4 according to the disk address stored in the area Va1. While the desired page contents are transferred to the memory 5 from a program store area 3 is said page contents are not stored in the area 4.

Title: Liquid growth method for semiconductor crystal
Inventor: SATO NAOTO
IPC: H01L21/28
Filed: 1989-01-31
Abstract: PURPOSE:To prevent roughing of surface of an electrode-formed layer even when the residue 4 of a growing solution is treated with HNO3 by a method wherein a protective layer, which is insoluble in HNO3, is grown on the electrode-formed layer. CONSTITUTION:A protective layer 3, which is insoluble in HNO3 but dissolves in HCl, is grown on an electrode-formed layer 2. Accordingly, as the electrode- formed layer 2, which dissolves in HNO3, is coated with the protective film 3 which dissolves in HNO3, only the residue 4 can be removed without being attached by HNO3. Subsequently, the protective film 3 is treated with an H2SO4 solution, the protective film 3 dissolves in the H2SO4 solution, and InP3 is removed. However, as the electrode-formed layer 2 is not attached by the H2SO4 solution, the electrode-formed layer having the clean surface is left. As a result, a clean surface having no roughness can be obtained.

Title: Current limiting circuit for dc motor
Inventor: NAKANO HITEMITSU
IPC: H02P7/288
Filed: 1981-02-19
Abstract: PURPOSE:To limit the flow of an excessive current by providing a voltage detector which detects as detected voltage a terminal voltage of a resistor in series with a DC motor as viewed from the output terminal of a bridge circuit. CONSTITUTION:Transistors 10, 9 are controlled in response to the differential voltage between the output voltage of a bridge circuit formed of resistors 2- 4 and a DC motor 1 and a reference voltage Vref of a reference voltage source 5. A limiting current detector 11 branches the base current of the transistor 10 when a transistor 12 is conducted ON if a voltage of the detecting terminal a of a bridge circuit is raised. As a result, the current supplied to the bridge circuit is limited. In this manner, it can limit the excessive current flowing through the speed controller when the DC motor is overloaded due to locking state for a long time or is shortcircuited accidentally.
