Abstract: PROBLEM TO BE SOLVED: To easily prevent the decline of element isolation capability caused by size reduction of a substrate. SOLUTION: A pad oxide film 2 and an SiN film 3 are formed on a silicon substrate 1 in this order, the laminated film is etched, and an opening part is formed at a part corresponding to a region where a field oxide film should be formed. An SiN film is formed on the SiN film 3 and the opening part for etching, and a sidewall 7 is formed at the opening part. Etching is made with the sidewall 7 and the SiN film 3 as a mask, a trench 8 is formed, and etching is made for retracting the sidewall 7. In this state, thermal oxidation treatment is performed, an oxide film 9a is embedded in the trench 8, and at the same time a LOCOS film 9 is formed at the opening part 5.  Even when the width of the LOCOS film 9 is narrowed by reducing the size of the substrate, since the trench 8 is formed and the oxide film 9a is embedded at the lower part of the LOCOLS film 9, preventing the continuity between elements at the lower part of the LOCOS film 9 is prevented, surely isolation the elements.

IPC: G06F13/362
Filed: 1990-03-20
Abstract: PURPOSE:To shorten the waiting time for answer with a simple circuit constitution by processing an answer transfer request in preference to a command request by means of a bus interface and a bus arbiter. CONSTITUTION:A buffer 72 stores the information showing whether a transfer request signal is equal to a command or answer transfer request signal. The output of the buffer 72 is directly inputted to an AND gate 74 and also to an AND gate 73 after inversion. The result of comparison showing whether the data on a comparator 41 to be transferred remains or not is inputted to both gates 73 and 74. If the data remains, a signal is outputted to a transmission control part 28 in response to the queue additional information. The part 28 transmits an answer transfer request signal RQH or a command request signal RQL to a bus arbiter 71 in accordance with a fact whether the queue additional information is identical with an answer or command request signal. The arbitra tion circuits 75 and 76 transmit the signals on the highest priority among those requests to an AND gate 77 and a NOR gate 78. Then a transfer grant signal GR is outputted to the answer transfer request in preference to the command request.

Title: Oil recovery device
Inventor: KUWANO MITSUO
IPC: E02B15/10
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To easily recover oil floating on the sea by applying soap resin salt to an oil recover device net used for recovering the oil. SOLUTION: The spread net 2 of an oil recovery device net 1 is fitted with a float 4 made of bagged vinyl 3 and a path root net pot 5 (recovered, oil reservoir). Also, a chuck 8 is provided with a path root end and soap resin salt is applied to the whole of the net 2. The oil recovery device net 1 so prepared is used to draw oil floating on the sea with two ships on the basis of a trawling system, and introduced into the path root net pot 5. The oil on the sea and the soap resin salt are repellent, against each other, thereby preventing the oil from passing even a large net mesh. In addition, oil introduced into the path root net pot 5 is collected into a tank, with the pot 5 lifted with a crane on board on an oil collection tanker 7 and the chuck 8 opened. Also, the float 4 has vinyl chloride filled with carbon dioxide and, when immersed in sea water, expands into a float.  Thus, as the oil does not escape even when the drawing net has a large mesh more or less, because of the use of the soap resin salt, the oil floating on the sea can be promptly treated offshore before drifted to the coast.

Title: Pager with voice recording function
Inventor: NITTA TOSHIO
IPC: H04B7/26
Filed: 1985-04-03
Abstract: PURPOSE:To transmit directly voice from a caller to a possessor of a pager by using a pager number from a radio paging transmitter so as to discriminate whether or not the transmission is addressed to the own transmitter, analyzing a reception frequency changeover code to switch the frequency and recording the voice from the caller after the changeover. CONSTITUTION:A signal from a radio paging transmitter is frequency-converted into an intermediate frequency f3 by a frequency mixer and demodulated by a detector 6. An own code discriminating circuit 7 discriminates whether or not a received signal is an incoming call to the own pager. In case of the incom ing call to the own pager, a reception frequency switching code is sent to a frequency switching code analysis circuit 8. The analysis circuit 8 uses the said code to decide a reception frequency f4 by which the own pager is to be switched, and the oscillating frequency f5 of a voltage controlled local oscilla tor 4 has a relation of f3=¦f5+ or -f4¦ by controlling a reception frequency switching circuit 11 so as to switch the frequency to the reception frequency f4. Then the voice from a calling subscriber is recorded by a voice recording circuit 9.
