Title: Molding device for mold material containing mold release agent
Inventor: ITO KATSUAKI
IPC: B29C45/02
Filed: 1988-03-09
Abstract: PURPOSE:To enable the title device to eliminate generation of a defective product and of a loss in operation hours resulting from a stain of a molding surface of a mold, by a method wherein an electric continuity measuring instrument for the molding surface of the mold is added and cleaning time of the mold is determined from a measured result with the measuring instrument. CONSTITUTION:An electric continuity measuring instrument 5 fitted to a bottom force is constituted of a spring probe 7 fitted to a holder 6, a power supply source 8 and an amperemeter 9 inserted into an electric circuit connected with the bottom force through this probe. In addition, degrees of stains of a top force 2 and the bottom force 3 progress almost in parallel with each other, therefore, it is sufficient when a degree of electric continuity of either one side molding surface is measured. Molding of a mold material is performed by shunting the spring probe 7 to a position inoffensive to the molding. Electric continuity measurement is put into operation by moving, for example, the probe onto the molding surface where a stain substance A is stuck prior to beginning of daily operation. The title device is constituted so that in case of measurement of an electrifying current value, the current value capable of maintaining the minimum mold release properties is obtained beforehand and when the current value exceeds a reference level based on the same, cleaning command is issued.

Title: Printed wiring board
Inventor: ONO TAKAHIDE
IPC: H05K1/09
Filed: 1989-03-10
Abstract: PURPOSE:To improve the flexibility of a printed wiring board and to contrive the improvement in characteristics against thermal distortion by composing the wiring circuit out of a super-elastic metal. CONSTITUTION:In a printed wiring board provided with a wiring circuit 4 mounted on an insulation base 1, the wiring circuit 4 is composed of a super- elastic metal. As a result, the tension, compression, and their repeated stress which are produced in a bent part of a flexible wiring board are absorbed by the deformation within the elastic area of the super-elastic metal, so that there is no disconnection suck as by cracks produced in the wiring circuit in spite of repeated bending of the flexible printed wiring board. In addition, the thermal distortion which is produced by the difference in thermal expansion coefficients of the composing members is absorbed within the elastic area of the super-elastic metal. Thus, the stable electrical conduction against bending and heat can be obtained.

The group 8 of receivers receives the group of response signals and then judges whether the signal level is over the fixed value or not. A judging circuit 10 judges agreement/disagreement by inputting the judged result 9 and the expected value signal 4 from the group 1 of drivers. A disagreement analyzing circuit 12 inputs a signal 11 for reporting the number of disagreement output terminals and thus analyzes the result of disagreement. A sign holding circuit 14 inputs the DUT discriminating sign signal 2 in said group 1 and the control signal 13 from said circuit 12 and then holds the DUT discriminating sign. A display device 16 displays the result 15 of disagreement analysis and the DUT discriminating sign.
