IPC: H01L29/78
Filed: 1988-05-25
Abstract: PURPOSE:To obtain a mask ROM having a large memory capacity for a unit area by a method wherein a conductor layer connected to a conductor layer is formed in a field region under a gate electrode corresponding to information to be stored. CONSTITUTION:A memory cell field region surrounded by a field oxide film 2 is formed on a P-type Si substrate 1 and a polycrystalline Si electrode 4 is formed on the field region with a gate oxide film 3 between. An N-type conductor region 5 is formed in the field region exposed from the electrode 4. A conductor layer 6 is formed also in the field region (gate region) beneath the electrode 4 by N-type impurity diffusion.

Inventor: DOI YASUTSUGU
IPC: G01P3/486
Filed: 1983-07-19
Abstract: PURPOSE:To obtain an inexpensive optical sensor of the number of revolutions superior in durability by arranging a thermally stable heat resisting light emitting element near an encoder to prevent the influence of an environmental temperature.

Title: Sulfur oxide gas sensor
Inventor: SAITO SATORU
IPC: G01N27/406
Filed: 1992-04-22
Abstract: PURPOSE:To prevent a sensor from causing delamination or cracking due to heat cycle so that the sensor can make accurate electromotive force measurement by using a specific bivalent metallic ion conductor for a solid electrolytic layer. CONSTITUTION:The sensor is constituted of a solid electrolytic layer 1, intermediate layer 2 made of sodium sulfate, platinum net 3 used as a working electrode, platinum paste 4 used as a reference electrode, etc. When a bivalent metallic ion conductor expressed by a general expression, MZr4(PO4)6 (where M represents a bivalent metal, such as Mg, Mn, Zn, Ni, Ca, Sr, Ba, Co, Cu, Pb, etc.), is used for the layer 1, the layer 1 hardly changes in volume even when its temperature changes between its operating temperature (about 500-700 deg.C) and room temperature, because the conductor does not have any phase changing temperature, and, therefore, the stripping off of the layer 1 caused by a heat cycle can be eliminated. In addition, since the conductor can be easily sintered without generating any very narrow hole nor crack caused by a heat cycle, no gas passes through the layer 1 and this sensor can accurately measure the electromotive force of an electrochemical system.

Abstract: PURPOSE:To eliminate hindrance to important operation of a terminal equipment controller by carrying out a data communication by using one of free communication lines if it is found by investigation that there are plural free lines. CONSTITUTION:When operation which uses the channel B of an ISDN line 6 is performed on one POS(point of sales information control) terminal 1a, a channel-B investigation message is sent to a LAN transmission/reception task.
