Title: Heat exchanger for thermoplastic resin and extruding method for the resin
Inventor: YAMAMOTO AKIKO
IPC: B29C47/78
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of foreign matter due to overheating and the decrease of the inherent viscosity by setting the molten resin and liquid contact surface of a static mixing element to specific surface roughnesses, and cooling the temperature of the liquid contact surface of the element to the temperature drop crystallization starting temperature or higher of thermoplastic resin with the molten resin by the cooling means of a cooling element. SOLUTION: A plurality of serial static mixing elements 3 are connected in, the cooling element 2 of a heat exchanger. As the example of heating means, a jacket type heating element 1 is provided at the outer periphery of the element 2 to cool the elements 3. The element 3 is measured at the temperature of the liquid contact surface 4 by inserting a thermocouple from the liquid contact surface 4 with liquid at 5mm or less, and held at the temperature drop crystallization starting temperature or higher of the thermoplastic resin. The surface roughness of the surface 4 is less than 6.3S to prevent the flowing irregularity and retention irregularity. The melted thermoplastic resin is fed from the fluid inlet 5 of the exchanger, passed through the element 3, and discharged from a fluid outlet 6.

IPC: G11B5/39
Filed: 1990-09-14
Abstract: PURPOSE:To obtain a magneto-resistance effect type magnetic head which has the gap narrowed in a track part and is free from short-circuit in a step part by giving a difference between the thickness of an insulating layer in the track part and that in the other part. CONSTITUTION:This head is provided with a magneto-resistance effect film 4a, a pair of conductor parts 5, shield layers 2 and 7 on and under the film 4a, and an insulator layers between shield layers 2 and 7 and the film 4a. The gap between the pair of conductor parts 5 is used as the track part where the magnetic flux signal from a magnetic recording medium is detected, and the thickness of insulator films 6a and 6b in the track part is made different from that in the other part. Thus, insulating layers 6a and 6b whose film thickness accords with design values are thinly accumulated on and under the track part of a magneto-resistance effect element to obtain the magnetic head coping with a high recording density, and short-circuit between a conductor and shield members in the step part is prevented because the film thickness of insulating layers 6a and 6b in the part other than the track part is increased.
