Title: Blow molding method
Inventor: TERADA KOSUKE
IPC: B29C49/78
Filed: 1991-11-11
Abstract: PURPOSE:To obtain a blow molding method by which molding is easily performed and the productivity can be enhanced. CONSTITUTION:Pressure (Pj), volume and temperature (Tj) of the air of the inside of a parison 1 are grasped in every time by controlling pressure (Ph), volume and temperature (Th) of the air blow from an air tank 3 at high temperature. A pre-blow stage, a blow-up stage or a cooling stage in a molding process is judged from the grasped volume of the air of the inside of this parison 1. The parison 1 is set at pressure and temperature of the air suitable for each stage and molded. When the volume of moldings is made equal to the volume of the inside of the parison 1, solenoid valves 12, 13 are opened and a solenoid valve 11 is closed. Air is introduced from an air tank 4 at low temperature. The air is controlled so that the flow rate discharged from the parison 1 is made equal to the flow rate supplied from the air tank 4 at low temperature. When cooling is finished, the solenoid valves 11, 12, 13 are closed and the moldings are taken out.

Title: Electromagnetic induction sensor
Inventor: SHINOZAKI HIROYUKI
IPC: G01B7/00
Filed: 1991-10-16
Abstract: PURPOSE:To lessen generation of eddy current in a conductor bulkhead of an electromagnetic induction sensor as much as practicable by forming a slit- form groove in the conductor bulkhead, which separates the target spatially. CONSTITUTION:Using a sensor circuit 4, and energizing current to work as a carrier of for example 1-100KHz is impressed on a sensor coil 3. With this energizing current, an alternate magnetic flux is generated in a magnetic circuity composed of a yoke 5, target 1, and gap between them. When this alternate magnetic flux passes through a bulkhead 2 of metal conductor, an electromotive force is produced in the bulkhead 3 by means of electromagnetic induction likely to cause generation of eddy current, which can however be mostly suppressed by extracting a groove deeply in the bulkhead 2. This groove 6 ties thin slit form counter-sunk holes 7, which can suppress the most of the eddy current going to be generated. Because the groove 6 is in slit form, the portion where the bulkhead 2 becomes thin is very narrow, scarcely presenting a structural change to the bulkhead 2, and there is little problem of imparing the strength of the bulkhead 2.
