Title: Dielectric porcelain compound
Inventor: KUROKI TSUNEJI
IPC: H01B3/12
Filed: 1987-10-14
Abstract: PURPOSE:To provide a dielectric porcelain compound with high dielectric constant, low loss of dielectric substance, good temp. change rate, high boost breakdown voltage, and low self heat emission by mixing SrTiO3, PbTiO3, Bi2O3.TiO2, Cu2O, MnCO3, and SrCO3 in a certain proportion. CONSTITUTION:0.05-2.0wt.% SrCO3, 0.05-0.3wt.% Cu2O and 0.05-0.3wt.% MnCO3 are added to a 100mol% compound consisting of 50-60mol% SrTiO3, 15-20mol% PbTiO3, and 20-30mol% Bi2O3.TiO2. The SrTiO3 improves dielectric constant and its temp. change rate, but excessive addition sinks the dielectric constant. Greater amount of PbTiO3 raises the dielectric constant, but excessive addition increase the temp. change rate and the self heat emission at the time voltage is impressed. Cu2O stabilizes the temp. change rate, but excessive addition sinks the dielectric constant, while SrCO3 improves crystal structure of the porcelain, and MnCO3 stabilizes further the dielectric constant and temp. characteristics. This accomplishes such characteristics as less change in dielectric constant with changing temp., less loss of dielectric sunstance, and high withstand voltage.

Title: Gas thrust bearing, gas radial bearing, spindle motor, and rotator device
Inventor: KOGURE TOSHIHARU
IPC: H02K5/16
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a rotator device reduced in an adhesion area between a bearing fixed member and a bearing moving member during starting and the starting load torque and the number of enduring times for the number of starting and stopping times. SOLUTION: A dynamic pressure creating groove 3 is formed in the opposite surface of one of a thrust bearing fixing member 1 and a thrust bearing moving member 2. Fine protrusions 4 are formed while kept away from the dynamic pressure creating groove 3. The fine protrusion 4 ensures a gap smaller than a gap during the creation of dynamic pressure during a stop. When the fine protrusion 4 is situated, the thrust bearing fixing member 1 and the thrust bearing moving member 2 are not adhered to each other throughout a whole surface during a stop of rotation and a parallel distance is held by a gap smaller than a gap during the creation of dynamic pressure. Thereby, the adhering area during starting is remarkably decreased and load torque during starting is eminently reduced, the number of enduring times for the number of starting and stopping times is remarkably increased, and the bearings are well suitable for the bearings of a polygon mirror, an HDD, and a spindle motor.

Title: Multibeam communication equipment and cdma mobile communication system
Inventor: SUZUKI KUNIYUKI
IPC: H04W52/02
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide multibeam communication equipment which can reduce the power consumption of a communication opposite station and can stabilize communication even if a maximum reception wave direction suddenly changes. SOLUTION: A base station 1 forms the reception beams RB1 and RB2 with half-value with required half-value width required. The base station 1 obtains transmission weight being a value obtained by normalizing the square root of the received power of the reception beams RB1 and RB2. The base station 1 forms the transmission beams TB1 and TB2 of a radiation pattern corresponding to the transmission weight in different positions in a sector SZ. Thus, a mobile station can always receive radio waves from plural directions, since a transmission route to the mobile station does not suddenly change. Then, power consumption can be reduced since a matched filter is not required to always operate. Even if a maximum reception wave direction changes in the middle of a data part, the data part can be demodulated. Thus, communication can be stabilized.

Title: Production of thermal fixing roller
Inventor: KON SHUJI
IPC: B29C67/04
Filed: 1986-10-31
Abstract: PURPOSE:To prevent generation of the cracks occurring in drying and thermal deterioration of a silicone rubber layer by coating a polytetrafluoroethylene resin (PTFE) dispersion on said layer, then heating and drying the coated surface at and for a specified temp. and time and baking the coating. CONSTITUTION:After the PTFE dispersion is coated on the silicone rubber layer formed on the core shaft of the roller, the coated surface is heated and dried for 10-120sec at >=500 deg.C and is then baked. The drying temp. of the coated surface is specified to >=500 deg.C, more preferably to a 500-800 deg.C range. The reason for such limitation lies in that cracks are liable to be generated at <500 deg.C and conversely there is possibility of the thermal deterioration of the silicone rubber layer when the temp. exceeds 800 deg.C. The generation of the cracks of the PTFE coated film is thus prevented by heating and drying the coated surface under the conditions of the temp. above 500 deg.C and the short time of 10-120sec. The thermal deterioration of the silicone rubber layer is prevented as well.

Title: Developer for electrophotography
Inventor: TSUBUSHI KAZUO
IPC: G03G9/087
Filed: 1988-10-18
Abstract: PURPOSE:To improve fixability, offset resistance and blocking resistance by incorporating a specific fluorine-contained graft copolymer as a resin component into the developer. CONSTITUTION:The fluorine-contained graft copolymer formed by graft polymerizing a fluorine-contained monomer with a backbone polymer contg. the compd. expressed by formula I is incorporated as the resin component into the developer. In formula I, R, R' may be the same or different and denote H or CH3, m denotes 1 to 20 integer. This fluorine-contained graft copolymer exhibits water repellent and oil repellent properties as compared to commercially marketed alternately polymerized or random polymerized fluorine-contained polymers; in addition the copolymer has excellent solubility in solvents and is hardly stickable to a heat roller at the time of heat roller fixing in the case of using the developer for a toner for electrophotography. Generation of offsetting is, therefore, obviated and the resin having the low softening point is usable for the toner material. The blocking resistance, fixability and offset property are improved in this way.
