Title: Method for extrusion-molding synthetic resin pipe
Inventor: NASU HIDEYUKI
IPC: B29C48/32
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To inhibit the generation of loss by measurement when a resin temperature is high and shorten a cooling process to set the dimensions of a finished product within a specified range by measuring the outside dia. and surface temperature of a pipe and an ambient temperature immediately after cooling and comparing these temperatures to the outside dia. design value of the pipe and a tolerance at a specific temperature entered separately to obtain the comparison results and further sounding an alarm when the comparison results are out of an acceptable range. SOLUTION: The outside dia. of a tubular-shaped pipe 6 obtained by extruding resin from an extruder 1 and shaping it by a mold 2, is measured using an outside dia. measuring device 4 at a high resin temperature immediately after cooling the resin to a temperature level which is lower than Tg but higher than a normal temperature, using a cooling device 3. Then, the resin surface temperature and the ambient temperature are measured with the help of thermometers 8, 9 respectively and the outside dia. design value of a finished product and the tolerance at 5 deg.C, 35 deg.C inputted separately are calculated using a coefficient of linear expansion. The calculated design value and the calculated tolerance are compared to the measured values.  In addition, simultaneously with the measurement of the outside dia., it is decided whether the pipe whose outside dia. is measured at a high temperature shows that the outside dia. of the pipe when it is finished as a product is within the acceptable range. When the outside dia. is out of the range, an alarm is sounded. Consequently, it is possible to detect an abnormality of the outside dia. at an early time to minimize the loss and further, cut the pipe immediately after curing of the resin to set it as specified and shorten a manufacturing line.

Title: Control device for electromagnetic clutch for vehicle
Inventor: SAKAKIYAMA RIYUUZOU
IPC: B60W10/02
Filed: 1980-11-19
Abstract: PURPOSE:To enable the smooth start of a vehicle even if its idling speed is high by varying the clutch torque in response to the variation when the idling speed changes. CONSTITUTION:When a choke or cooler is operated the idling speed becomes high. Since signals from a choke detection switch 40 and a cooler detection switch 45 are inputted to a correcting circuit 49, a rotating speed detector 48 produces a pulse wave via a pulse generator 47. Since the idling speed of the vehicle during stoppage is Ne', when an accelerator switch 39 is depressed, coil current gradually increases, and when it becomes an ordinary speed Ne, it flows a rated current Im, thereby directly coupling the clutch. Thus, smooth starting can be performed even if the engine speed is accelerated, and when the speed is then decelerated, the engine brake can be operated to the prescribed speed.
