Title: Semiconductor memory device
Inventor: ITO MASARU
IPC: G11C11/41
Filed: 1994-09-14
Abstract: PURPOSE: To contrive a low dissipation of power by avoiding useless power consumption of a semiconductor memory device. CONSTITUTION: A selecting circuit 2 selects the specified memory cell of a memory cell array 1. A reading circuit 3 reads out the data of the selected memory cell. A writing circuit 4 writes the data into the selected specified memory cell. A first control circuit 5 reads the data out of the selected memory cell by controlling the reading circuit 3 in the same cycle of a clock signal and then writes the data to be read at the next time into the selected memory cell by controlling the writing circuit 4. A comparing circuit 6 compares the read-out data of the selected memory cell and the writing data.  A second control circuit 7 prohibits the writing of the data to be written into the selected memory cell by nullifying the control of the writing circuit 4 with the first control circuit 5 when it is judged that the read-out data and the writing data are same from the result of the comparison with the comparing circuit 6.

IPC: C07D501/08
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To industrially and advantageously produce the subject compound useful as an intermediate for antibiotic substances, etc., by reacting an azetidinone derivative with phosphorus pentachloride in the presence of an HCl scavenger in an organic solvent, then successively reacting the resultant compound with a chlorinating agent and an alcohol, hydrolyzing the prepared compound and subsequently treating the hydrolyzed compound with a base. SOLUTION: An azetidinone derivative of formula I [R<1> is a (substituted)aryl, arylmethyl or aryloxymethyl; R<2> is a protecting group of carboxyl group; R<3> is a (substituted)aryl] is reacted with phosphorus pentachloride in the presence of a hydrogen chloride scavenger in an organic solvent to produce an iminochloro derivative of formula II, which is then reacted with a chlorinating agent to provide a chlorinated iminochloro derivative of formula III. The resultant product is subsequently reacted with an alcohol to produce a chlorinated iminoether derivative, which is subsequently hydrolyzed to form a 3- aminoazetidione derivative (salt) of formula IV. The prepared 3-aminoazetidinone derivative (salt) of formula IV is further reacted with a base in an organic solvent and cyclized to thereby industrially and advantageously afford the objective 3-cephem derivative of formula V.

Title: Device for reducing noise of centrifugal compressor
Inventor: YOSHIUMI HIROTO
IPC: F04D29/66
Filed: 1992-08-20
Abstract: PURPOSE:To efficiently reduce vibrations and noises of a centrifugal compressor respectively by providing two rows of guide blades of a diffuser in the direction of flow while disposing resonance type silencers between the respective guide blades over the whole circumference centering around a rotary shaft. CONSTITUTION:In operating a centrifugal compressor, a stationary wave 2 caused by columnar resonance in a resonance pipe of a section having guide blades and a diffuser wall perpendicular thereto surrounded is generated in a section of the diffuser with the guide blades. Then, the noise caused by the stationary wave is maximized by the sound wave having half-wave length in the resonance pipe, i.e., having the half-wave length equal to the length of a diffuser vane 1. Thus, the diffuser is halved at the nodal portion of the stationary wave 2 in the direction of flow, Resonance type silencers 3 are disposed between two rows of diffusers over the whole circumference centering around a rotary shaft, so that the vibration and noise of the centrifugal compressor can be efficiently reduced respectively.

Title: Lens driving device
Inventor: IMASHIRO AKIHIKO
IPC: G02B7/08
Filed: 1990-08-22
Abstract: PURPOSE:To reduce an overshoot and remaining vibration and to enable great noise reduction by rounding the time waveform of an applied voltage at the time of switching to an opposite polarity from a zero voltage along an exponential function and specifying the time constant of this rounding. CONSTITUTION:Capacitors C1 - C4 are connected to the terminals of resistances R2, R6, R12, and R18, connected to the bases of transistors TR1 - TR4, on the opposite side from the TRs 1 - 4. The other-terminal sides of those capacitors C1 - C4 are grounded and resistances R21 and R22 are connected to the collectors of TRs 7 and 8. When a TTL signal S1 is switched from a low level to a high level, the collector current of a TR 5 varies while delayed by the time constant determined by the resistance value of a resistance R3 and the electrostatic capacity of the capacitor C1. At this time, the applied voltage of stator winding is rounded with R/C according to the exponential function by using the capacitance C of the capacitor C1 and the resistance value R of the resistance R3. In this case, the time constant of the rounding should be >= (1/4) time as large as the characteristic period of a motor rotation system.
