Filed: 1992-08-26
Abstract: PURPOSE:To reduce the number of ROM and wiring used for numerical arithmetic. CONSTITUTION:Correlation (an early signal correlation vector) between a pseudo random code advanced to a pseudo random code for demodulation just for a prescribed phase and a received spread spectrum signal, and correlation (a delay signal correlation vector) between a pseudo random code delayed for a prescribed phase and the spread spectrum signal are calculated.

Title: Method for applying lining to inner surface of manifold
Inventor: KAWAZOE MASATO
IPC: B05D7/22
Filed: 1988-09-12
Abstract: PURPOSE:To prevent the remaining of an uncoated part and lap-coating by detecting that coating reaches a branch part at the time of lining from the end part of a branch pipeline to the branch part on the basis of the variation of the gas pressure generated in the main pipeline on the upstream side of a branch part in a lining method for injecting coating in a pipe and feeding air therein. CONSTITUTION:A necessary amount of the coating in a main pipeline is injected in the end part of a pipeline 5 and compressed air is sent from the end part 6. the lining of the main pipeline 1 is finished while the coating is almost prevented from flowing in branch pipelines 10A-10C. Next, a necessary amount of the coating from an end part 11A to a branch part 12A is injected from the end part 11A to be sent by air. Since the pressure of the gas in the pipe on the upstream side of the main pipeline 1 is slightly increased when the coating reaches the branch part 12A, said pressure is detected by a pressure gauge 24 to finish the lining of the branch pipeline 10A. The other branch pipelines B, C are also subjected to lining treatment in the same way. By this method, lap-coating is prevented and the wastefulness of the coating can be prevented. The lining of the main pipeline may be performed after that of the branch pipes.

Title: Actuator for magnetic disk device
Inventor: OTSUKA KYOICHI
IPC: H02K33/18
Filed: 1990-08-31
Abstract: PURPOSE:To prevent the positioning accuracy of a head being lowered without inclining the shaft of a movable part by fixing the laminating part of a yoke by tightening with a screw via an auxiliary part connected to a base. CONSTITUTION:Torque applied when a yoke fixing screw 16 is tightened is transmitted from the bearing surface of the yoke fixing screw 16 to a yoke fixing auxiliary plate 14, however, since the yoke fixing auxiliary plate 14 is fixed with a yoke fixing auxiliary plate mounting screw 15, the torque is not transmitted to the laminating part of the yoke 1, and only the axial tension of the screw is applied to the laminating part of the yoke 1, which prevents torsion from remaining in the yoke 1. Also, since no torque is transmitted to the laminating part of the yoke 1 even when the residual torsion of the screw is released by the effect of temperature fluctuation or secular change, no deviation of the laminating part of the yoke 1 occurs. In such a way, it is possible to prevent the deviation of the laminating part of the yoke which makes worse the positioning accuracy of the head occurring by the effect of temperature fluctuation and secular change, and to accurately read information.

Filed: 1993-08-19
Abstract: PURPOSE:To eliminate through current in the input stage to reduce the power consumption by using three CMOS circuits each of which consists of a pair of a pMOS transistor TR and an nMOS TR which have drains connected to each other. CONSTITUTION:When a low level output signal of a low voltage circuit 4 is applied to gates of a pMOS TR P1 and an NMOS TR N1 of a first CMOS circuit 1, the TR P1 is turned on, and the potential at a point A goes to +5V. Then, an NMOS TR N2 of a second CMOS circuit 2 is turned on, and the potential at a point B goes to -9V, and the TR N1 is turned off. However, a pMOS TR P3 of a third CMOS circuit 3 is turned off, and the potential at a point C goes to +15V, and a TR P2 is turned off, and the potential at the point B keeps -9V. When a high signal level is applied to them, potentials at points C, B, and A go to 0V, +15V, and -9V respectively to turn off the TR N2, and the point B keeps +15V. Consequently, the through current doesn't flow to the input stage whether an input signal IN is +5V or 0V, and further, the circuit can be constituted of only six MOS TRs.
