Title: Treatment of dilute aqueous solution containing urea
Inventor: INOUE SHIGERU
IPC: C07C239/00
Filed: 1982-11-05
Abstract: PURPOSE:To separate and drive out the whole volume of ammonia and carbon dioxide with one column by executing the 1st stripping such as distillation of a dilute aq. soln. contg. urea, etc., and the 2nd stripping in the space in the same column. CONSTITUTION:A dilute aq. soln. for a treatment A contg. urea, ammonia and carbon dioxide is pressurized with a pump, and is then supplied to the top of a stripper which is preheated to 126 deg.C by heat exchange with the discharge liquid from the stripper at 146 deg.C. The dilute aq. soln. for the treatment A supplied into the stripper is subjected to stripping by the steam blown from the column bottom during descending in each stage, by which ammonia and carbon dioxide are driven from the soln. and are discharged as a bottom liquid from the column bottom. The bottom liquid is cooled by heat exchange and is then reduced to the pressure of the stripper. Such liquid is fed into the stagnating part for the treating liquid B which is the 7th stage from the top of the stripper, where the liquid is subjected to the stripping effect in exactly the same way as in the treatment A.

Title: Controller for hybrid automobile
Inventor: KITAJIMA YASUHIKO
IPC: B60L50/16
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent knocking and the like, without changing the total torque of power plants. SOLUTION: The controller is for parallel hybrid automobile, provided both with an engine E and with a motor M as power plants for the vehicles. A torque command distributing means 10 calculates a command value if total torque to be output from both the engine E and the motor M, from an accelerator opening signal. The torque command distracting means also calculated a command value of engine torque in the total torque, to be output from the engine E. A torque distribution correcting means 20 corrects the command value of engine torque, based on the condition of the vehicle, such as knocking, and calculates a new command value for the engine torque, The torque distribution correcting means 20 also calculates a command value of motor torque to be output from the motor M, based on the command value of engine torque and the command value of total torque.  Torque which is equivalent to engine torque but reduced for the prevention of knocking is compensated for, by the use of the motor torque.

Title: Laser diode module
Inventor: HATTA TATSUO
IPC: G02B6/42
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a laser diode module capable of arbitrarily adjusting the direction of polarization of light to be emitted and arbitrarily adjusting oscillation wavelength of light to be emitted by turning a fixed polarization optical fiber around an optical axis of the fixed polarization optical fiber and adjusting a polarization face of laser beam entering the fixed polarization optical fiber. SOLUTION: Since a dielectric multilayer film filter 15 can turn around a rotary axis 17 as shown by an arrow mark 22, a central penetration band is changed by this turn, namely, inclination of the dielectric multilayer film filter 15. As a result, oscillation wavelength of a laser diode 1 can be adjusted to an arbitrary wavelength. On the other hand, since a fixed polarization optical fiber 18 is physically separated from a mode expansion fixed polarization optical fiber 7, it can arbitrarily turn centered on an optical axis of the fixed polarization optical fiber 18 as shown by an arrow mark 23. Consequently, the direction of polarization of laser beam transmitted in the fixed polarization optical fiber 18 can be arbitrarily adjusted, namely, selected.

Abstract: PROBLEM TO BE SOLVED: To surely measure the resistance value of unvulcanized semiconductive silicone rubber composition by holding the unvulcanized semiconductive silicone rubber composition between metal electrodes and making a current of not more than a specific value flow thereinto. SOLUTION: A silicone rubber composition S is held between two parallel metal electrodes (anode, cathode) and a current of not are than 5mA is made to flow thereinto to obtain a resistance from the current and a voltage. Namely, an anode 1 and a cathode 2 are respectively fixed by nonconductive plates 3, 4 made of an acrylic resin or the like. Also, the anode 1 is connected to a plus terminal of a voltage/current control power source 5 through a lead wire 6 and at the same time the cathode 2 is connected to its minus terminal through a lead wire 7. Next, in that state, a current of not more than 5mA, preferably, not more than 2mA is made to flow thereinto to obtain a resistance from a current value and a balanced voltage value at that time. When a current made to flow exceeds 5mA, temperature of a material is increased by consumed power and an accurate resistance is not obtained.

Title: Equalization of equalizer positioning and its circuit
Inventor: SUBERIIRU ORAFUSON
IPC: H04L25/03
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To stabilize equalizer positioning by centering the tap coefficient of an equalized response generated by an equalizer when a signal sample having a sampling phase is received as an equalizer input. SOLUTION: When a receive signal sample is supplied to an equalizer 11, an equalizer coefficient 12 is generated, differences between squares of a first and a last equalizer tap coefficients are accumulated in a equalizer shift estimator 13, and the accumulation is carried on up to two most center taps. Then the accumulated difference is compared with a threshold value and scaled by a scale 14 when exceeding the threshold value, and supplied to a timing recovery circuit 16 so as to shift the sampling phase. Namely, a timing bias signal 17 is generated and the sample phase of a received signal is shifted so as to shift the equalized response to a more center position. Therefore, the timing bias signal 17 has its bias removed by the timing recovery circuit 16 and the equalized response is stabilized at a new position.

Title: Method and device for disinfecting edged tool
Inventor: TAKAHASHI YUSAKU
IPC: A45D27/46
Filed: 1991-05-01
Abstract: PURPOSE:To disinfect the edged tool by a method being harmless to the human body by blowing hot air thereto. CONSTITUTION:When a razor 1 is put into a heating chamber 9, a switch 2 works, and electric conduction is executed simultaneously to a heating wire 5 and a fan 6. Hot air generated as its result is blown to the razor and it is heated and disinfected. By a timer after a heating time determined in advance, or when the surface of the razor is heated to a temperature determined in advance, a temperature sensor works, the electric conduction to the heating wire is stopped, and heating of the razor is suspended. The fan feeds continuously air of the normal temperature for another prescribed time, and cools the razor. By the timer after a cooling time determined in advance, or when the surface of the edged tool falls to a temperature determined in advance, the temperature sensor works, and the electric conduction to the fan is stopped. In such a way, the heated and disinfected edged tool is cooled in a short time, and can be reused. Since a disinfectant is not used, this method is harmless to the human body.
