Title: Power steering device
Inventor: YOSHIZAWA YUJI
IPC: B62D5/083
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To improve the connecting strength in the rotating direction by pressing a steel ball into the axial hole of a torsion bar, expanding it in diameter, forming a small irregular face on one of the outer face of the torsion bar and the axial hole of an input shaft into which the torsion bar is inserted, and forming the other into a smooth face. SOLUTION: A torsion bar 11 formed with an axial hole 26 at one end and provided with serrations (small irregular face) 25 on the outer face is inserted into the axial hole 24 of a smooth face formed at one end of an input shaft 14. A steel ball 26 is pressed into the axial hole 26 of the torsion bar 11 to expand in diameter, then one end of the torsion bar 11 is uniformly crimped over the whole periphery of the axial hole 24 of the input shaft 14. The serrations 25 of the torsion bar 11 bite into the smooth face of the axial hole 24, the pressing force for a unit area is increased by the reduction of the contact area between the serrations 25 of the small irregular face and the smooth face of the axial hole 24, and the torque strength (connecting strength) in the rotating direction is improved.

Title: Vessel for aseptic culture of plant
Inventor: YASUNOBU YOSHIKO
IPC: A01H4/00
Filed: 1990-08-03
Abstract: PURPOSE:To facilitate the observation and photographing of a plant in an aseptic culture vessel by subjecting the inner wall of the vessel to hydrophilicizing treatment, thereby decreasing the contact angle of water droplet, joining the adjoining droplets with each other and forming the surface of the wall like a water-surface. CONSTITUTION:The main body 6 of a plant culture vessel has a cylindrical form. A cellulose acetate resin sheet 8 of about 0.1mm thick is pasted to the inner side wall of a plastic layer 10. The lid 7 of the plant culture vessel and the inner side wall of the plastic layer 11 are also covered with cellulose acetate sheets 9 of about 0.1mm thick. As an alternative method, the main body 18 and the lid 19 of the plant culture vessel are made of cellulose acetate resin 20, 21 and the outer wall is made of a moisture-proofing resin layer 22. Since the inner wall is made of a resin layer having hydrophilic group, the water droplets are joined with each other to form a wall surface like a water surface. Although diffused reflection of light takes place on the surface, it is extremely small compared with conventional vessel. The transmittance of light is also improved.

IPC: H01L21/66
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To accurately measure the superposing deviation between actual circuit patterns. SOLUTION: A first superposition measuring mark composed of a linear pattern having the same size as that of the design rule of a first circuit pattern, and a second superposition measuring mark 2 composed of a linear pattern having the same size as that of the design rule of a second circuit pattern are provided.

Filed: 1987-08-24
Abstract: PURPOSE:To efficiently recovery medium for the generating plant in the caption by providing a recovery tank through a conduit branched from a Rankine cycle and providing a heat exchanger for cooling the tank in a Rankine cycle type generating plant. CONSTITUTION:LNG is guided to flow through a conduit 21 branched from a conduit 10 in Rankine cycle system to a heat exchanger 9 installed in a recovery tank 8. The LNG cools the gas of Rankine cycle medium in the recovery tank 8 to condensate the gas so that pressure in the recovery tank 8 drops.

Simultaneously, LNG is guided to flow continuously through the heat exchanger 9 so that the pressure in the Rankine cycle drops gradually. Accordingly, the gas in the Rankine cycle system is continuously absorbed in the recovery tank 8. In a case of recovering the medium to exchange the equipments of the Rankine cycle system substantially the whole amount of the medium of the Rankine cycle can be recoveried through this method and the medium can be recoveried inexpensively and efficiently.

Title: System for compensating equalizer characteristic
Inventor: MIYAKO TAKASHI
IPC: G11B5/035
Filed: 1988-08-24
Abstract: PURPOSE:To demodulate digital signal at a low error rate by emphasizing the high-band characteristics of the frequency compensating characteristics of an equalizer circuit which compensates the characteristics of digital signal reading signals while the peak level of the reading signals drops from a prescribed level. CONSTITUTION:While the level of peak hold signals Vpk inputted from a peak hold circuit 12 drops from a prescribed correction reference level Vs, an equalizer correction control signal generation circuit (EQCG circuit) 14 generates a correction control signal Ceq and supplies the signal Ceq to an equalizer (EQ) circuit 12. The EQ circuit 12, peak hold circuit 13, and EQCG circuit 14 form a loop. Namely, the EQCG circuit 14 compares the inputted peak hold signal Vpk with a prescribed correction reference level VS and supplies the correction control signal Ceq to the EQ circuit 12 during the period when Vpk<Vs. The correction reference level Vs is set to, for example, about 70% of the normal peak level of the peak hold signal Vpk. Therefore, digital signals can be demodulated excellently at a low error rate.

Abstract: PURPOSE:To reduce a fan sound without impairing an exhausing performance of a fan by a method wherein a speaker emitting a sound in the same direction of a fan sound is disposed on an outside surface provided with the fan in proximity to the fan. CONSTITUTION:A fan sound 12, such as a motor sound, is produced in a fan 2. The fan sound 12 is picked up by a microphone 3 as a sound 2g together with a noise and converted to electric signals 3h. Fan sound signals 10 based on the fan sound 12 are extracted out of the electric signals 3h by a fan sound signal extraction circuit 4. Succeedingly, reverse-phase signals 11 having a phase reverse to the fan sound signal 10 are produced by a reverse-phase signal producing circuit 5. The reverse-phase signals 11 are converted to a masking sound 13 by a speaker 6. The masking sound 13 is emitted in the same direction of the fan sound 12. The masking sound 13 having a phase reverse to the fan sound 12 offsets the fan sound 12 so as to reduce the fan sound 12.
