Abstract: PURPOSE:To exclude the waste of chip relief, by a method wherein units of small regions where the inside of an integrated circuit is divided and designed exist in the peripheral part of a wafer, and the small region units which are not imperfect are transferred from the part of the wafer periphery, which does not constitute the integrated circuit, to a part which constitute the integrated circuit. CONSTITUTION:Chips 2 in a wafer 1 have no defects and normally arranged, and peripheral chips 3 are imperfect chips. The macro 4 existing in the inner chip 2 and the macro 5 existing in the peripheral chip 3 have the same coordinate positions in the respective chips. When a defect exists in the macro 4 of the inner chip 2, said part is eliminated and can be replaced by the macro 5 of the peripheral chip 3. By the division design of a chip in which the macro is used as an unit, it becomes possible that an imperfect chip is eliminated and an perfect chip is buried in the eliminated part and the macro of the peripheral chip 3 which can not be used as a chip is economically utilized.

Title: Method and device for recording information
Inventor: FUKUDA YASUSHI
IPC: G11B7/00
Filed: 1992-02-13
Abstract: PURPOSE:To reproduce information without recognizing resynchronization patterns at a demodulation circuit by including information reproducing codes right before and behind the resynchronization patterns to the pattern which is inserted every pre scribed interval of the recording information. CONSTITUTION:The pattern, in which seven zeros are continuous and after that six are continued, does not exist in the transformation rule of a 1-7 modulation circuit 9. When a synchronization information consisting 00, 11, 01, 10, 01, 01, 01, 11 and 01 is inputted to the 1-7 modulation circuit as the input data, for every prescribed interval of the recording information, patterns 30 to 33 are obtained for every recorded pattern with a prescribed amount and they differ to each other depending on the codes of recorded information inputted to the circuit 9 right before and after the synchronization information. By an irregular generating circuit 10, patterns 34 to 37 are made by replacing the tenth one to zero. A pit length switching code 39 is included between post information reproducing patterns 001 and 000 and it is switched to '0' or '1' in accordance with the outputs of a pit length measuring circuit 13 and a discriminating circuit 14. Having this constitution, the demodulation circuit reproduces recording patterns right before and behind the resynchronization pattern without recognizing resynchronization patterns.

Title: Apparatus for dipping up surface part
Inventor: FURUKAWA TOSHIHIKO
IPC: E02B15/04
Filed: 1982-02-23
Abstract: PURPOSE:To perform the work efficiently automatically dipping up the surface part of a liquid, by rotating a liquid-receiving box in response to its vertical motion caused by the variation of its weight so that the lower lip of its opening moves up and down over a distance longer than the stroke of said vertical motion. CONSTITUTION:Oil on the surface of a liquid flows into a box 11 beyond the lip 13 of the opening 12 of an oil-reversing box 11 supported with long holes 9, 9 and a horizontal shaft 10 between floats 6 and 6 moving up and down as an integrated body coupled with a connecting plate 7 along rod guides 5, 5. As the box 11 is gradually sunk in water by the weight of the inflow oil, the shaft 10 moves downwards, and pinions 17, 17 at the ends of the shaft 10 engage with the racks 16, 16 of the floats 6, 6 to rotate the lip 13 upwards. When a predetermined amount of oil is reserved in the box 11, it is discharged outside through a draining pipe 18 by a pump. Consequently, the box 11 gradually floats up. As a result, the lip 13 of the opening 12 maintaining the contact with the oil layer rotates downwards. In this case, the distance of the vertical rotation of the lip 13 becomes longer than the stroke of the vertical motion of the box 11.

Title: Air/fuel ratio control device for internal combustion engine
Inventor: SAWAMOTO KUNIAKI
IPC: F02D41/04
Filed: 1991-02-21
Abstract: PURPOSE:To prevent shocks from being caused by an abrupt drop in torque when air/fuel ratio is switched to the lean side for improvement of fuel consumption. CONSTITUTION:The air/fuel ratio control device calculates the fuel injection quantity based on the intake air flow Q detected by an air flow meter 3 and derives a fuel injection valve 5 so that the air/fuel ratio reaches a target air/fuel ratio. When the target air/fuel ratio is switched to the lean side, a bypass control valve 7 installed to a bypass passage 6 bypassing a throttle valve 4 is opened and driven. Thus, the air flow Q is increased, and in response to the increased air flow the fuel injection quantity is so controlled as to obtain the target air/fuel ratio on the lean side to restrict an abrupt drop in the fuel injection quantity.

Abstract: PURPOSE: To prevent a varistor from being destructed and to prevent the internal stray capacitance included in the varistor from affecting on lines by connecting a means (varistor) for determining the peak voltage of a dial pulse between the lines only during the generation of dial pulses and disconnecting the means from the lines during the period of communication. CONSTITUTION: When an S relay 4 is switched to the modem 8 side and then a CML relay 2 is switched to the modem 8 side, lines L1, L2 are closed. When a dial number is inputted, a P relay 3 is closed, the S relay 4 is switched to the varistor 5 side and a CPU 10 repeats the opening and closing of the P relay 3 in accordance with the inputted dial number to generate dial pulses.
