IPC: C23G1/19
Filed: 1987-12-16
Abstract: PURPOSE:To perfectly dissolve and remove slightly soluble scale formed and stuck on the surface of an iron-based metal by applying a mixed soln. prepd. by adding an amine type alkali agent and hydrazine hydrate to polyaminocarboxylic acid and adjusted to a prescribed basicity. CONSTITUTION:An amine type alkali agent is added to an aq. soln. of polyaminocarboxylic acid (e.g., EDTA) having 10-30wt.% concn. to adjust the pH to 6.5-9.0. The polyaminocarboxylic acid is converted into salt and a chelating agent which easily forms chelate with a scale forming metal is produced. Hydrazine hydrate is then added to the chelating agent to adjust the pH to 7.0-9.5 and a corrosion inhibitor such as an org. amine type inhibitor is further added. By applying the resulting mixed soln., slightly soluble scale formed and stuck on the surface of an iron-based metal is perfectly dissolved and removed at 120-160 deg.C. One or more among an aq. ammonia soln., gaseous ammonia, morpholine, cyclohexylamine, mono-, di- and triethanolamine are used as the amine type alkali agent.

IPC: H01L27/088
Filed: 1990-11-20
Abstract: PURPOSE:To enable each element formation region to be insulated and separated without increasing production process by allowing a thickness of a first shielding layer from one edge to other edge to exceed a thickness from a main surface of a specified region to a shape position of a second shielding layer and then forming a shielding layer for electrically shielding the specified region. CONSTITUTION:A poly-Si film 3 is formed at a lower layer of an SOI region where an N-channel MOS transistor 13 or a P-channel MOS transistor 14 is formed but it is insulated and separated from a poly-Si layer 11 due to an oxide film 9 so that no current is conducted by the poly-Si film 3 even if a potential is given to the poly-Si layer 11 through an AI electrode 16. However, the poly-Si film can function as a shield fully even if no current is conducted. Therefore, even if a drain potential of an Si substrate 1 fluctuates greatly due to operation of a vertical-type power MOS transistor 15, each SOI region is not affected by it and can be stabilized electrically. Also, one edge of the poly-Si layer 11 is formed in a depth which is nearly equal to the poly-Si film 3. Thus electrical influence between adjacent elements can further be reduced.

Title: Controller
Inventor: KAWAMURA FUMIO
IPC: G06F3/023
Filed: 1990-11-22
Abstract: PURPOSE:To reduce the number of wires in a harness by fetching signals outputted from delay circuits to a CPU side through switches while a scan signal outputted from the CPU is delayed successively by plural delay circuits, and the switches are operated. CONSTITUTION:The delay circuits 104-1 to 104-n to input the scan signal delay it by Td in order. In such a case, if the switches SW1, SW3 are in a closed state, a state signal is outputted at the timing of '1' of each output terminal. The CPU 1-2 scans the state of a state terminal by an input port at every Td time by an internal interval timer. Then, if the state of the state terminal is '1', it decides that the switch corresponding to this timing is in an ON-state, and if '0', it decides that it is in an OFF state. Thus, the number of wires in the harness can be reduced, and assembling in a device becomes easy.
