Title: Auxiliary braking and auxiliary power device
Inventor: KANEMITSU MASAHIRO
IPC: B60L50/15
Filed: 1994-05-18
Abstract: PURPOSE:To raise the efficiency of auxiliary braking and regenerative braking by relating the control of the inverter circuit between the AC circuit of a squirrel cage induction electric machine linked directly to the rotation shaft of the internal combustion engine of a car and the DC circuit of a battery, with that of the automatic gear of a power transmitting circuit. CONSTITUTION:In the case of generating a braking force in a rotation system, an inverter control circuit 5 applies, to the stator of an AC squirrel cage induction electric machine 2, a rotating magnetic field having a speed smaller than the rotation speed of the rotor of the induction machine 2 detected by a rotation sensor 6. The induction machine 2 becomes a generator, and generated electric energy is converted into DC by an inverter 4 and charges a secondary battery circuit 3. When a braking torque is too large for the secondary battery 3 to absorb, a semiconductor switch 12 connects a resistor 11 to the terminal of the secondary battery 3. At the time of applying a driving force to the rotation system, the inverter control circuit 5 makes the speed of the rotating magnetic field of the squirrel cage induction machine 2 higher than the rotational speed of its rotor, and it operates as a motor. As a result of this, it becomes possible to raise the efficiency of auxiliary braking and regenerative braking.

Title: Optical isolator
Inventor: KONNO YOSHIHIRO
IPC: G02B27/28
Filed: 1988-04-28
Abstract: PURPOSE:To easily obtain the optical isolator whose plane of polarization is maintained at low cost by coupling a 2nd Faraday rotator which is magnetized in an opposite direction with either of the incidence and projection sides of the optical isolator. CONSTITUTION:The 2nd Faraday rotator 4 which is magnetized by a permanent magnet 6 in the opposite direction from an arrow H is coupled with the incidence side of the polarizer 1 of the optical isolator consisting of the polarizer 1, the Faraday rotator 3 which is magnetized as shown by the arrow H, and an analyzer 2. In this constitution, the incidence and projection polarization planes are maintained in a forward direction 0, but rotated by 45 deg. through a 1st Faraday rotator 3 in the opposite direction R, so orthogonal polarization is obtained for the polarizer 1 and a light beam is cut off. The same effect is obtained even when the 2nd Faraday rotator 34 is provided on the projection side of the analyzer 2. Thus, the number of components can be decreased and the low-cost polarization plane maintaining optical isolator which facilitates optical axis adjustment is obtained.

Title: Gas mixer of gas introduction pipe of diffusion furnace for semiconductor
Inventor: NOZAWA TATSUO
IPC: H01L21/223
Filed: 1989-04-24
Abstract: PURPOSE:To obtain a gas mixer being free from a problem of corrosion due to oxidation by forming a spiral vane plate on a shaft and by constructing the same of a material such as an SiC sintered substance or an Si-impregnated SiC material. CONSTITUTION:A shaft 5 of a mixer 4 and a spiral vane plate 6 are formed of an SiC sintered substance or an Si-impregnated SiC material. In an ordinary oxidative gas containing oxygen and others, an SiC material has larger oxygen resistance at a high temperature than metal such as stainless steel, causing no problem in this regard. Since any form can be given freely to the SiC sintered substance or the Si-impregnated SiC material in adhesion and it can be bonded, in addition, formation of a complicated shape, such as the spiral shape, is enabled. Accordingly, a mixer being excellent in corrosion resistance, having a simple structure and enabling attainment of a uniform gaseous body can be obtained.

IPC: F24D11/00
Filed: 1990-04-20
Abstract: PURPOSE:To prevent lowering of a room temperature at midnight and to prevent the occurrence of excessive heating by setting a first stage energizing period in which a heat generating body is energized from the starting time of a midnight power time zone and a second stage energizing period in which a heat generating body is energized from a given time set retroactively from the completion time of the midnight power time zone. CONSTITUTION:When a controller 7 receives a midnight power, correction computing is effected by a correction computing part 14. Namely, a first stage energizing period is which energization is effected for a specified time starting from the starting time of a midnight power time zone, a second stage energizing period set retroactively from the completion time of the midnight power time zone, and a reference set temperature are determined. The heat generating body 1 is energized during the first stage energizing period, and a relay 10 is operated so that a detecting temperature from a temperature sensor 6 is kept at a set temperature. When the first stage energizing period is completed, a room temperature is detected by a room temperature sensor 15. The detecting room temperature is compared with two thresholds by means of an abnormality detecting part 18, and when a comparing result is below a threshold on the low temperature side, the starting time of the second stage energizing period is advanced to increase the second stage energizing period. Reversely, when a room temperature is threshold abnormality on the high temperature, the second stage energizing period is shortened. Indoor heating matching a live time zone is practicable.

Abstract: PURPOSE:To reduce production of NOX at a low cost by a method wherein by injecting fuel at a superhigh pressure through a plurality of fluid injection nozzles each having a fine nozzle, lean fuel-air mixture having uniform fuel concentration is prepared, and thereafter, the lean fuel-air mixture is burnt. CONSTITUTION:A small amount of fuel F1 is injected in air A, flowing out as it is revolved by a swirler 3, through a vortex injection valve 2 to perform diffusion combustion. Meanwhile, fuel F2 is injected through the fine nozzle of a fuel injection nozzle 1 at a superhigh pressure having a differential pressure of 50kg/cmP<2> or more between the air A in a combustor 5 and the fuel. The fuel F2 injected through the fuel injection nozzle 1 is pulverized to produce spray B, which is vaporized and mixed with the A to produce fuel-air mixture C. With the progress of the flow of the fuel-air mixture C toward the downstream of the combustor 5, an amount of air in the spray B is increased to bring the fuel-air mixture into a lean state, and distribution of fuel concentration is uniformized. Thereafter, the lean fuel-air mixture C is ignited by using a spread flame D through the injection valve 2 to perform low temperature combustion in which an amount of NOX produced is reduced.

After this, a strobe signal SB is output to allow the latched data DT to be recorded on thermal recording paper. In addition, a drive pulse PD is applied to a motor drive part 22 each time the predetermined number of data Dr is processed. Consequently, a stepping motor 23 is actuated to move thermal recording paper by one step.
