Title: Switching regulator
Inventor: NAKAMURA SHIGEO
IPC: H02M3/28
Filed: 1991-11-11
Abstract: PURPOSE:To avoid a current detection element becoming a principal heat source and suppress the temperature rise of a switching regulator by providing the iron core of the inductor of a smoothing circuit with a gap, and inserting a Hall element, and using it as a current detecting means. CONSTITUTION:A switching means Q is connected to the input winding T1 of a transformer T, and input DC voltage V1 is applied. A diode D1 is connected to one end of the output winding T2 of the transformer T, and a smoothing circuit C is connected to this diode D1. With the direction headed for the negative side of the diode D1 from the junction between the return line of this smoothing circuit C and the other end of the output winding T2 of the transformer T as a forward direction, a flywheel diode D2 is connected. A Hall element H is inserted in the gap G of the iron core CO of the inductor L constituting the smoothing circuit C, and the output voltage of this Hall element H and the output voltage V0 of the circuit C are fed back to a control means R. The heat generation of the Hall element H is extremely small, and the temperature rise of the switching regulator is suppressed remarkably.

Inventor: YAMADA AKINORI
IPC: B61D27/00
Filed: 1987-11-24
Abstract: PURPOSE:To improve service to passengers by setting a target set temperature, setting a target set humidity in line with a temperature below the target set temperature, and carrying out a dehumidifying operation so as to make the humidity inside a vehicle the target set humidity when the temperature inside the vehicle is below the target set temperature. CONSTITUTION:A controller 8 detects the temperature and humidity of an air conditioning space by means of a temperature sensor 10 and a humidity sensor 12 while receiving a target set temperature from a temperature setter 9. When the temperature in the air conditioning space (inside a vehicle) is above the target set temperature, a cooling operation is carried out. Also, when the temperature inside the vehicle is below the target set temperature, the detected result of the temperature inside the vehicle is judged and carries out a dehumidifying operation so as to obtain the target set humidity which is set in line with the temperature. Thereby, always comfortable humidity can be obtained regardless of temperature change inside the vehicle.

Title: Production of polymer particle
Inventor: IMAMURA TAKESHI
IPC: C08F2/00
Filed: 1991-11-11
Abstract: PURPOSE:To efficiently obtain polymer particles having a narrow particle diameter distribution by introducing a liquid feedstock into the space between two coaxial cylinders disposed vertically and polymerizing the feedstock by suspension polymerization while rotating either or both of the cylinders around the axis so as to generate Taylor vortexes. CONSTITUTION:An inner cylinder 2 is coaxially disposed in a cylindrical reactor 10, and the cylinders 2 and 10 are installed with the axis 6 extending perpendicularly. A liquid feedstock 9 (e.g. styrene solution) is introduced into the space between the two coaxial cylinders 10 and 2, and at least either of the cylinders 10 and 2 is rotated around the axis 6 to generate Taylor vortexes in the feedstock 9. Thus, low-shear mixing flows are formed. That is, flows in the form of stacked doughnuts are formed and circulate around the axis 6 in the same direction. However, when the doughnut flows are viewed on a cross section including the axis 6, any pair of two adjacent doughnuts also has reverse rotations R. Due to such flows, the suspension polymerization is conducted with sufficient stirring to thereby obtain polymer particles having a low coarse particle content.
