Title: Oversampling a/d converter
Inventor: ITO YUICHI
IPC: H03M3/04
Filed: 1988-10-14
Abstract: PURPOSE:To obtain an S/N close to an ideal state without deteriorating the S/N even at a part where a high input level exists by providing an offset cancel means to cancel an offset component included in the output of a digital filter, and a gain error correction means to correct a gain error generated in the inside. CONSTITUTION:The title device is constituted of an oversampling encoder 1, the digital filter 2, an offset cancel lation circuit 3, and a gain error correction circuit 4 to correct the gain error. The offset cancellation circuit 3 sets a training period where no signal is inputted to the oversampling encoder 1, and detects the offset component of the encoder 1 in that period. The offset component is subtracted from the output of the digital filter 2, and a result is outputted to the gain correction circuit 4. Next, the gain correction circuit 4 calculates gain error correction count in a gain error measuring period, and corrects the gain error generated at the encoder 1 by multiplying the output of the encoder 1 in an ordinary operation by the gain error correction count.

Title: Semiconductor memory device
Inventor: KAWAGOE TOMOYA
IPC: G11C11/406
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To eliminate useless electric power consumption by making a refresh cycle time longer as a whole by means of providing each row with a refresh cycle setting circuit and setting the refresh cycle in conformity with that of the lowest memory storage capability cell of each row. SOLUTION: An address registration circuit 1.1-1.r (here, r: a natural number smaller than the number of row address), an entire refresh cycle setting circuit 2, a gate circuit 3, and a refreshing operation prohibition circuit 4 are added to a conventional DRAM. Also, a timing circuit 31 outputs an activation signal ϕ1 to activate each of the address registration circuit 1.1-1.r and the entire refresh cycle setting circuit 2, and an activation circuit ϕ1 is a same signal as an activation signal ϕR, ϕSA or a delay signal. Since an output ϕCBR of a decision circuit 33 is at 'L' level at the time of normal writing/reading operation, an address selector 35 gives a row address RA to a row address decoder 37. Also, a refresh permission signal ϕ2 becomes 'H' level, and AND gates 4a, 4b allow the activation signals ϕSA, ϕR to pass through them.  Thus, a memory cell MC specified by a row address RA and a column address CA is selected and writing/reading of data is performed.

Title: Dc-dc converter
Inventor: YAIRO OSAMU
IPC: H02M3/155
Filed: 1989-10-04
Abstract: PURPOSE:To reduce the power loss of a DC-DC converter by using a field-effect transistor of the conductivity type opposite to that of a field effect transistor (p-channel FET) for PWM. CONSTITUTION:A field effect transistor(FET) Q4 is an N-channel FET, the conductivity type of which is opposite to that of a P-channel field effect transistor Q1 for PWM. The FET Q4 is cut off when the FET Q1 for PWM conducts to energize a load through a smoothing circuit SC. When the Q1 is cut off, on the other hand, the FET Q4 conducts to supply the lead with the energy stored in a smoothing inductance L1. The resistance of the FET Q4 is smaller than that of a flywheel diode. According to this method, the power loss of a DC-DC converter can be reduced.

The pitch is developed on the plate 3 as a liq. film by action of centrifugal force, and scattered in a spray form from the periphery of the plate 3. The pitch sprayed then flows down the inside wall of the apparatus 1, and discharged out of the apparatus through a pitch outlet 4. At that time, the low-boiling gas components contained in the pitch are separated. The low-boiling gas components are removed through a low- boiling gas component outlet 5 by the use of a vacuum pump, etc. The pitch coming out of the pitch outlet 4 is fed to a spinning apparatus through a gear pump.

IPC: H03K3/02
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction even if deviation in timing due to changes of source voltage and temperature conditions is generated by extracting the degree of delay of timing varying owing to variation in source voltage, etc., in operation and gate delay and selecting as a clock frequency a frequency corresponding to the degree of the delay. SOLUTION: A delay detecting circuit 2, register circuits 5a and 5b, and a CPU 10 constitute a delay detection control means; and the delay detecting circuit 2 mainly detects the delay of a signal and the CPU 10 mainly controls other circuits.
