Title: Catv emergency broadcasting receiver
Inventor: SAKAGUCHI HIDETO
IPC: H04N21/41
Filed: 2000-08-24
Abstract: PROBLEM TO BE SOLVED: To power-save a waiting state of an emergency broadcasting information at a CATV receiving terminal equipment. SOLUTION: At a waiting state time, a tuner 1 is tuned with an RF default. When an emergency broadcasting detector 3 detects an emergency broadcasting detection signal, a power source controller 13 starts a main power source. A controller 10 reads a channel RF emergency transmitted via an emergency information descriptor from a nonvolatile memory 12, and transits the tuner 1 to the RF emergency. A CATV reception terminal equipment detects the descriptor and judges that an installation area of the receiving terminal equipment corresponds to an object to be emergency broadcast if an area code in the descriptor coincides with a regional code stored in the memory 12 and an emergency broadcasting start/end flag is = 1, and warns emergency by means of an alarm buzzer 11.  The emergency notice is finished when the start/ end flag becomes '0', tunes the tuner 1 with the RF default, turns off the main power source, and again returns to the waiting state.

Title: Method of manufacturing optical waveguide element
Inventor: OTOMO KATSUYA
IPC: G02B6/13
Filed: 2000-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing an optical waveguide element by which completion of a flattening process can be detected without measuring level difference on the substrate surface. SOLUTION: The completion of the flattening process can be detected by only visually checking that a mark 2b for detection of the completion of the flattening process coated with an opaque material film 6b is changed into transparent because the opaque material film 6b is removed during the flattening process. This eliminates the level difference 4, and therefore, measurement of level difference 4 is not required. By forming the mark 2b for detection of the completion of the flattening process near the layer to be flattened, accuracy for the detection of the completion of the flattening process can be improved.

Title: Semiconductor device
Inventor: SHIMOIDA YOSHIO
IPC: H01L27/04
Filed: 2000-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which has the function of protecting semiconductor elements against abnormal voltages and which is suppressed with increase in chip area and chip cost. SOLUTION: In this semiconductor device, a circuit block, consisting of a plurality of electrically insulated and isolated elements is formed in an active layer substrate of the so-called 'SOI type' semiconductor substrate, where a low density supporting substrate 1 and a low-density active layer substrate 3 are electrically separated by an insulation film 2. The supporting substrate is a P-type, and the active layer substrate is an N-type, with the supporting substrate being fixed to VSS (ground).  Due to this structure, a depletion layer which extends in the horizontal direction, between the supporting substrate and the active layer substrate when a transient abnormal voltage is applied can be formed wide, and the capacity coupling to other insulated islands can be reduced, thus preventing malfunctions of the semiconductor device due to surge voltage of either the positive or the negative polarity. Because there is no need for conventional N+ type embedded layer and deep N+ type diffusion layer, manufacturing processes can be simplified and cost can be reduced, and the chip area can also be reduced.
