Title: Transmitting device
Inventor: AKATSUKA KAZUKI
IPC: G08B21/00
Filed: 1980-01-22
Abstract: PURPOSE:To realize a transmission for the data having an emergency trouble in a small effective value of voltage, by detecting the trouble by checking whether the change component of voltage has exceeds the prescribed value or not and at the same time storing the time of detection into a memory. CONSTITUTION:The A/D converter 2 delivers the sample value, and the buffer memory 8 delivers the precedent value to sampling. The subtractor circuit 10 checks whether the value of change between the sample value and the 1-sample precedent value is larger than the prescribed value or not. If the value of change is larger than the prescribed value, the rewriting of data is started at the control circuit 5 to the memory 3. At the same time, the time of trouble detection is supplied to the memory 3 from the counter 9. When the data storage of a fixed time is over, the data of trouble is transmitted by the coder 4.

Title: Vertical type metal oxide semiconductor transistor
Inventor: HOSHINO SHIGEO
IPC: H01L29/08
Filed: 1983-01-19
Abstract: PURPOSE:To prevent the element breakdown due to a breakdown current and thus improve the strength against a surge by a method wherein a semiconductor layer of the first conductivity type and medium concentration is provided between a substrate of the first conductivity type and high concentration and the semiconductor layer of the first conductivity type and low concentration wherein a well region of the second conductivity type, and the bottom of the well region reaches the semiconductor layer of the first conductivity type and medium concentration. CONSTITUTION:The withstand voltage of the P-N<+> junction between the bottom of the P type well region 7 and the N<+> type region 15 of medium concentration is lower than the withstand voltage of the corner of the region 7, and thereby breakdown previously occurs at the P-N<+> junction in case that a reverse directional voltage of high voltage such as a surge is impressed between the drain/source. This is because a generated depletion layer does not expand very much in the N<+> type region of medium concentration, since the impurity concentration of the N<+> type region 15 of medium concentration is thicker than that of an N<-> type region of low concentration 16, and then because an electric field concentrates at the thin part of this depletion layer. The breakdown current (c) flowing at this time uniformly flows over the wide range of the P-N<+> junction, therefore the phenomenon that the breakdown concentrates at the corner is eliminated.

IPC: H01L21/822
Filed: 1991-01-24
Abstract: PURPOSE:To provide a semiconductor device including stacked capacitors with increased capacitance by compensating for the limitation of lithography to increase the area of a storage capacitor formed in a cell region. CONSTITUTION:When patterning the storage electrode for a stacked capacitor, a removable film 25 is formed on a conductive film 19A for the storage electrode. The removable film is selectively etched to form a groove 8 that exposes the conductive film 16A at the periphery of the storage electrode. Another removable film 25B is deposited on the side walls of the groove 8 to such an extent that the groove is not completely filled. As a result, the grooves becomes narrower than the size limited by lithography. The conductive film 19A is selectively etched through the groove, and the conductive film left on the cell region is used as the storage electrode.

Title: Optical disc apparatus
Inventor: MORITA SHUJI
IPC: G11B7/085
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To enable a stable focus pull-in operation even when imbalanced focus error signal is used in an optical disc apparatus. SOLUTION: In the case when a pull-in failure determination process 19 determines that detection of S-character fails, because of the small peak of the S-character appearing first in the S-character detection process 18, the pull-in control 16 instructs a re-pull-in process 22 for detecting the S-character on the polarity side different from that of the S-character detection process 18. Therefore, stable focus pull-in operation may be realized even with the imbalanced focus error signal.

Abstract: PURPOSE:To prevent a malfunction due to the misinsertion of a ROM by writing the version number of a program which is stored in division over plural ROMs into each ROM and checking automatically the version number written before execution of the program. CONSTITUTION:The M(M11, M12) serve as ROMs which store a program in division.

The version number PN shows the number of version of the program which is coded and written into the prescribed area of the ROMM11 and 12 respectively. Then the PN is checked by a prescribed procedure before execution of the programs stored in the ROMM11 and 12. In other words, the PNs stored in the ROMM11 and 12 respectively are compared with each other. When the coincidence is obtained between both PNs, the program is executed. While an alarm is delivered to show the abnormal combination of ROMs and the subsequent operations are stopped in case no coincidence is obtained between both ROMs.
