Title: Echo canceller
Inventor: FURUKAWA HIROMOTO
IPC: H04B3/23
Filed: 1986-09-19
Abstract: PURPOSE:To minimize the deterioration of two-way simultaneous talking at transmission/reception changeover and the insertion loss by controlling a transmission/ reception side insertion means, inserting a minimum loss not causing howling to a line and decreasing an interruption threshold value for a transmission/reception signal so as to facilitate the interruption. CONSTITUTION:An insertion loss operating means 16 operates a loss not causing howling from the output of a maximum value operating means 14. Then the means 16 receiving the talking state discriminated by a talking state discriminating means 15 to give an operated insertion loss to the receiving side at the transmission state to the receiver side and gives it to the transmission side at the receiving state. Moreover, in case of the two-way simultaneous talking state, the means 16 gives it to the receiving side at the transmission priority and gives it to the transmission side in case of the reception priority. Thus, transmission/reception side loss insertion means 7, 6 are controlled to insert a required minimum loss not causing howling to the line so as to decrease the interruption threshold value for a transmission/reception signal, thereby facilitating the interruption. Thus, the initial adaptation of a voice switch is made and the insertion loss and the deterioration in the two-way simultaneous talking performance are minimized.

Title: Aluminum product having superior anticorrosive effect
Inventor: KOBASHI TAKAO
IPC: C23F13/00
Filed: 1982-12-20
Abstract: PURPOSE:To prevent effectively the progress of the corrosion of an Al product clad with a cathodic protective layer due to heavy metallic ions contained in corrosive environment by sticking metallic pieces having lower electrode potential than the heavy metal on the protective layer. CONSTITUTION:The body A of a heat exchanger is made of an Al clad material consisting of an A1100 alloy as a core material 1 and an A7072 alloy as a shell material (a cathodic protective layer) 2 with the material 2 inward. Many metallic pieces 3 made of an Al-0.04% In alloy are stuck on the material 2 of the body A with an adhesive 4 (electrically insulating layers) so that the number of the pieces 3 at a part close to the inlet 5 for water used as a medium is made larger than that at a part close to the outlet 6. When heavy metallic ions such as Cu ions are contained in water for the body A, the pieces 3 capture and remove the heavy metal, so the remarkable initial corrosion of the layer 2 is inhibited, and the formation of white rust can be prevented.

Title: Detecting liquid of liquid leakage
Inventor: NIIKURA MASAMI
IPC: G01M3/20
Filed: 1982-12-23
Abstract: PURPOSE:To obtain a detecting liquid by which the leakage of lubricating oil or fuel due to the cracks of an engine or the like or the poor condition of a seal can be seen without causing a fire, an explosion nor affecting the maleffect to the human body and the environment, by dispersing uniformly fine power such as talc in a solvent consisting essentially of water incorporated with surface-active agent. CONSTITUTION:As a solid component, talc, alumina or the like having 1mu <= grain diameter is used so as to invade easily into tiny cracks. To make the dispersion of the powder to a solvent uniform, to make the permeation of the solvent into the cracks easy, and to promote drying of water according to the temp. of a machine to be measured, a proper quantity of alcohol is added to the solvent consisting essentially of water incorporated with surface-active agent to make a detecting liquid. If it is necessary for anti-corrosiveness of a metal, it is possible to make a liquid leakage detecting liquid in which a rust preventive agent (NaNO2 or the like) is dissolved. The detecting liquid is applied on the surface of a machine by spraying or the like. If there is no crack or the poor condition of a seal, dried white powder is formed on the surface, however, on the part having leakage of oil or the like from the inside, wet white powder adheres to the surface and is not scattered easily. Thus, the leakage due to the tiny cracks or the like can be seen surely.
