Abstract: PROBLEM TO BE SOLVED: To make it possible to surely and frictionally hold a lead through the application of a clamping force caused by an elastic clamping means to the lead in addition to the elastic action of a lead holding piece itself by arranging the elastic clamping means, which gives an elastic binding power to lead holding pieces at the expanding of the lead holding pieces, in the holding part main body of the lead holding part. SOLUTION: When a lead 5 is inserted in the lead insertion hole 11 of a slider 12, a plurality of lead holding pieces 17 are expanded by a lead abutting against a lead holding surface 18 so as to frictionally hold the lead 5 by the elastic force of the lead holding pieces 17 themselves. In this case, a clamping force is added by an elastic clamping means. Concretely, when a plurality of the lead holding pieces 17 expand, to a coiled spring 13 fitted to a holding part main body 15, a force, which expands the bore of the spring, is applied, the restoring action of the spring 13 applies a clamping force to a direction, which presses the lead 5. Further, a clamping force is applied to a direction, which presses the lead 5, to the lead holding pieces 17 by an elastic piece 21 provided between the lead holding pieces 17 and a support 20.

Filed: 1977-09-20
Abstract: PURPOSE:To eliminate the influence from the noises of a transmitting circuit by balancing the inpedance at the detecting element side from the positive and negative input terminals of a pre-amplifer with the use of a balance resistor and a coupling capacitor. CONSTITUTION:The detected output of a photoelectric conversion detecting element 1, which is balanced by a negative resistor 7 grounded to the earth through balance resistors 9a and 9b, is impressed through a double core sheld wire 8 upon the positive and negative terminals of a pre-amplifier 4, respectively, so that the differential output corresponding to the detected value is generated from the amplifier 4. The wire 8 and the amplifier 4 are connected by means of coupling capacitors 10a and 10b and grounded DC balance resistors 11a and 11b so that the impedance, if the element 1 is seen from the side of the amplifier 4, is completely balanced in DC and AC manners. As a result, the detected value, which is generated by the amplifier 4 in a differential amplification, is cleared from the outside noises so that the transmission of satisfactory signals having a wide range can be accomplished.

Abstract: PURPOSE:To protect an input stage of controlling a small signal even if an output stage malfunctions by providing input protecting means for blocking the arrival of the malfunction state of the output stage at the input stage. CONSTITUTION:In order to avoid the forward connections of parasitic diodes D1, D2 from an output stage to an input stage, an n<+> type emitter diffused layer 4 and a p<+> type base diffused layer 3 are set through a contact region OP5 to the same potential, and disposed adjacently without an n<-> type layer 2 therebetween.

Title: Molding equipment for plastic material
Inventor: ISHIZAWA KENKI
IPC: B29C48/58
Filed: 1985-05-27
Abstract: PURPOSE:To reduce the mechanical wear and chemical corrosion of the member of the titled equipment by a structure wherein at least one member among members in contact with plastic material is made of ceramics. CONSTITUTION:Fillers violently contact with a nozzle 9 and a nozzle needle 11 due to the high speed turbulent flow of resin of the fillers mixed with the resin at the throttled bore part of the nozzle 9 during injection molding. As a result, wear proceeds on the nozzle 9 and the nozzle needle 11. When the injection molding is stopped, local wear due to sliding contact occurs through the fillers by the intermittent pressing pressure developed with the opening and closing movement of the nozzle needle 11. By employing a ceramic nozzle needle 11 and a ceramic nozzle 9 or by utilizing the wear resistance and high corrosion resistance of the ceramic, the service life of the members of the molding equipment can be prolonged.
