Title: Method of reheating polyester preform for blow molding
Inventor: UEIN ENU KORETSUTO
IPC: B29C49/64
Filed: 1987-06-23
Abstract: A hybrid reheating of polyester preforms which are to be stretch blown into containers wherein the reheating coupled with the controlled quick initiation of the blow stretch operation after final reheating produces a container which may be filled with a hot fill without there being any disadvantageous shrinkage of the container. The reheating is by way of a specific combination of quartz oven reheating and radio frequency reheating together with specific equilibrations of the temperature cross sectionally of the preform body. Polyester preforms may be reheated to a cross sectional center temperature ranging from 225 DEG F to 260 DEG F and stretch blow molded without undesirable surface crystallization occuring while the ability of the container to be filled with a hot fill substantially without shrinkage is increased.

Abstract: PURPOSE:To reduce the power consumption even with the use of a circuit which supplies a resistive signal to a signal input part by outputting a control signal of a 1st level to turn on a switch means in a 1st mode and then by outputting a control signal of a 2nd level to turn off the switch means in a 2nd mode respectively. CONSTITUTION:In a 1st mode, a control means 18 outputs a control signal of a 1st level and this control signal is applied to an input terminal 9 of a logic circuit 14 and a control terminal 10 of a switch means 15. Thus the means 15 is turned on and a resistive signal is applied to the input terminal of the circuit 14. At the same time, the input signal applied to an input terminal 1 is transmitted to an output terminal 3. In a 2nd mode, the means 18 outputs a control signal of a 2nd level. Thus the means 15 is turned off and no current flows to the means 15. At the same time, the output of the circuit 14 is forcibly set at a certain level regardless of the level of the input signal applied to the terminal 1.

IPC: B60K5/12
Filed: 1992-06-16
Abstract: PURPOSE:To reduce a size of a device and mountability onto a vehicle body by preventing generation of both noises caused by minute oscillations of an engine and shock caused by its large oscillations. CONSTITUTION:A rod 11 is connected to a piston 3 reciprocable inside a cylinder 2, while a rod 11 is projected outward from an end of the cylinder 2. An inner space of the cylinder 2 is divided into a main chamber 18 and an end chamber 19 by a partition wall 17. A through-hole 17 and an orifice 21 are formed on the partition wall 17 at one moving end position of the piston 3. A check valve 22 is arranged in the through-hole 20 for allowing the flow from the main chamber 18 to the end chamber 19 only. A groove 25 and a bypass pipe 26 are formed for communicating the main chamber 18 with the end chamber 19 on both ends of the piston 3 within the range distanced from an intermediate position P of the piston 3 to both sides in moving directions of the piston 3 by specified length L. Therefore, minute oscillations of an engine are thus absorbed by oscillations of the piston 3, and large oscillations of the engine are suppressed by the movement of the piston 3 to the partition wall 17 and its slow return thereafter.

That is, the output where the 20kHz level is -46dB with respect to the reference level is obtained and the output difference between the generators 1 and 2 is takes as the adjacent interference ratio. Then the accuracy is increased the measuring time is reduced with less errors by measuring the value while the output of the generator 1 is matched with the RF level and changed.
