Title: Key telephone system
Inventor: YAMASHITA HIDEO
IPC: H04Q3/58
Filed: 1988-03-11
Abstract: PURPOSE:To prevent costup and to make the size of the key telephone set small by storing number guide information, displaying the number guide information to a key telephone set and dialing a dial signal automatically according to the displayed number guide information. CONSTITUTION:A storage section 2 stores the number guide information required for the system as storage data. Then in case of selecting optional number guide information, when a function button for selecting number guide information is depressed, a key telephone set 1 sends new number guide information to a relevant key telephone set 3 and the information is displayed on a liquid crystal display section 5 of the key telephone set 3 again. Through the operation above, after the required number guide information is selected, when the function button for automatic dialing is depressed, the key telephone set 3 reads the telephone number of the number guide information from a liquid crystal display section 5 and sends it as dial information to the key telephone set 1 for automatic dialing. Thus, the cost is reduced and the operability is improved.

Title: Method for detecting surface flaw of glass
Inventor: YAMAUCHI HIDEO
IPC: G01N21/958
Filed: 1991-02-27
Abstract: PURPOSE:To detect a flaw separately from other defect by judging that two cells are continuous when the interval between two cells whose defects are detected is preset length or less to perform continuation processing. CONSTITUTION:An inspection area is divided into arbitrary cells and, when the interval between two cells judged to have a defect is equal to or less than preset length, they are regarded to be continuous ones. For example, when the length of one side of a cell is set to 100mum and the interval between two cells having a minute flaw is 100mum or less, two cells are judged to be continuous to perform continuation processing and this flaw is detected as 100mum. When the interval between two cells having a flaw is 300mum or less, by the continuation processing of two cells, the flaw is detected as 700mum and the length of dust is detected as 200mum. When a defect longer than 200mum is preset as an inferior product and a defect of 200mum or less is preset as a good product, dust can be judged to be a good product and a flaw can be judged to be an inferior product.

The values of the voltage e(x, t), the current i(x, t) and their time-dependent partial differentiations (for example, e(x, t)= e(0, t)- {Ri(0, t)+L.di(0, t)/dt}x) at a place having a distance of x from the electric station are obtained by the judgement circuit Dc' from the output of the differentiation circuit Df, an inductance L, a resistance R, a capacitance C and a conductance G which are distributed constants per unit length of a power transmission line. The trouble can be detected from a first-degree equation of x obtained by the judgement circuit Dc'. An original time ralay of much higher capability than a frequency relay based on a conventional AC theory can be thus be provided.
