Title: Manufacture of solid-state image pickup device
Inventor: MATSUNAGA MASAYUKI
IPC: H01L29/762
Filed: 1990-11-30
Abstract: PURPOSE:To enable an opening whose width is narrower than that of a mask to be formed by forming a thin film by self aligning on a side wall part of the mask with an opening by photolithography. CONSTITUTION:A polycrystalline silicon film 13 is deposited on a semiconductor substrate 10 through a gate insulation film 12 and then an SiO2 film 14 is deposited on it by the CVD method, etc. Then, a photoresist 15 is spread on the SiO2 film 14, a stripe-shaped opening is made on the resist 15 by photolithography, and further the SiO2 film 14 is selectively etched with the resist 15 as a mask. A gap L1 should be equal to approximately 1mum which is a limit of lithography. Then, after eliminating the resist 15, an SiO2 film 16 is deposited on an entire surface by the CVD method, etc. By performing etching of the SiN film 16 by anisotropic etching, the SiN film 16 is allowed to remain at an opening edge part of the SiO2 film 14, thus enabling a gap L2 of the opening to be narrower than L1.

Title: Piezoelectric transformer
Inventor: TAKANO KATSUYOSHI
IPC: H01L41/107
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To inject large power, restrain heat generation, and prevent influence of frequency change, by driving a device at a frequency in the region where a vibration mode in the length direction and a vibration mode in the width direction are coupled. SOLUTION: Input electrodes 11 are formed on both surfaces of one side of a rectangular piezoelectric ceramic plate 10, and an output electrode 12 is arranged on an end surface of the opposite side. The ratio of the length L and the width W of the piezoelectric ceramic plate 10 is set nearly equal to 2. When driving is performed at the region where a vibration mode in the length direction and a vibration mode in the width direction are coupled, a high voltage at the time of lighting start of a fluorescent lamp is obtained. A high voltage is also obtained when lighting is continued. Therefore, the input of a high voltage is enabled, and heat generation can be restrained. Hence effective driving is enabled without being affected by the change of resonance frequency.

Title: Tunnel disaster preventive facility
Inventor: SHINO TOSHIHIKO
IPC: G08B29/18
Filed: 1992-12-24
Abstract: PURPOSE:To preclude water misdischarge even when the MPU of a repeating board runs away. CONSTITUTION:The receiving process part 20 of the repeating board 4 once receiving an automatic valve control instruction signal from a crime preventive board 3 outputs the signal to a cutoff circuit 22 and outputs a specific coded signal to a control check circuit 21, which only when inputting the specific coded signal outputs a cutoff reset signal to the cutoff circuit 22 and outputs the automatic valve control instruction signal to an automatic valve input/output circuit 23. When the receiving process part 20 runs away, the probability that the specific coded signal is outputted to the control check circuit 21 is extremely low and even when a signal other than it is outputted, the control check circuit 21 does not output the cutoff reset signal to the cutoff circuit 22. Therefore, the cutoff circuit 22 is still closed and even when a command control part which runs away outputs the automatic valve control instruction signal to the cutoff circuit 22, an automatic valve 6 is never opened by mistake.
