Title: Production of polyoxymethylene whisker
Inventor: IGUCHI MASATOSHI
IPC: C08G2/04
Filed: 1983-04-23
Abstract: PURPOSE:To obtain polyoxymethylene whiskers which can be easily and satisfactorily dispersed in water, by simultaneously performing both the polymerization short-stopping and the surface treatment for imparting hydrophilicity by adding a surfactant to a solution for short-stopping the polymerization of trioxane. CONSTITUTION:In producing polyoxymethylene whiskers by polymerizing trioxane, a surfactant is added to a solution for short-stopping the polymerization and the solution is used to perform simultaneously polymerization short stopping and the surface treatment for imparting hydrophilicity. Solvents for trioxane which can be suitably used are nonpolar solvents such as aliphatic hydrocarbons, alicyclic hydrocarbons and hydrocarbon mixtures. The concentration of the surfactant is preferably 5-1,000ppm based on the polymerization short-stopping solution. When this concentration is excessively low, the solution can not make a full contribution to the hydrophilicity of whiskers, while when it is excessively high, an aqueous dispersion of the whiskers tends to foam during making into paper, which is undesirable.

Filed: 1985-04-08
Abstract: PURPOSE:To make rapid and stable the detection by detecting both the output of the detecting device to detect the error ratio and the AGC control voltage, and judging that the receiving signal is turned off when either of these goes to be the stipulated value or above. CONSTITUTION:When the receiving input electric power is decreased, the code error ratio is measured by a counter 23, it is judged that the receiving signal input is turned off when the prescribed stipulated value is exceeded and a receiving signal input turning-off detecting signal 24 is sent to an OR gate 22.

Title: Semiconductor integrated circuit and its test method
Inventor: YAMAMOTO SHINGO
IPC: H03K19/0175
Filed: 1995-03-30
Abstract: PURPOSE: To reduce the measurement errors of output currents of output buffers that are caused by the contact resistance of a metallic probe brought into contact to the electrode of a semiconductor integrated circuit in every measurement state. CONSTITUTION: The output buffers B1 to Bn have the input and output terminals connected between an input terminal 2 and an output terminal 3 and also have the test control terminals T1 to Tn respectively. The outputs of buffers B1 to Bn have high impedances due to the test signals which are supplied to the terminals T1 to Tn. When the electrical characteristic is measured by an 1C tester, a normal drive operation is given only one of buffers Bl to Bn with other buffers set at high impedances respectively. Then the output current of a single output buffer is first measured and then other buffers also undergo the measurement of their output currents in the same way. The sum total of these measured current value is defined as the output current of a high-drive output buffer 1, so that the output current can be reduced in every measurement.  Then the voltage drop error due to the contact resistance of a metallic probe caused in a measurement state can be reduced.
