Inventor: HASEGAWA HITOSHI
IPC: B29C48/305
Filed: 1990-03-30
Abstract: PURPOSE:To obtain the above thermoplastic resin film or sheet with good quality colored zone by a method wherein molten colored resin flowing through a path is heated or cooled by heating or cooling the neighborhood of the path, which is connected to a manifold, of the molten colored resin. CONSTITUTION:Molten uncolored resin is fed through a circular path 17 on one side end of a mold main body 11 to the inlet part of a manifold 12, passed through an enlarged land 14 and extruded through a slit 15 in the form of film. Molten colored resin is fed to the inlet part of the manifold from the direction normal both to the extrusion direction of resin and to the distribution direction of resin in the manifold in the form of a slit. The molten colored resin passing through a slit-like path 21 is heated and cooled by flowing heating and cooling fluid, which is controlled to a certain temperature, in the inner pipe 32 of a heating and cooling pipe 30. Thus, the fed colored resin meets the uncolored resin layer running in a land 13 in layer, resulting in forming colored zone having deep color near the inlet part of the manifold and light color at the part far away from the inlet part of the manifold through shading off. And, the resin is extruded through the slit 15 in the form of film or sheet.

Abstract: PURPOSE:To eliminate the useless operation time of a platen, by providing a means for detecting the feed-direction length of a sheetlike original conveyed from an original feeder to the platen, to control the length of reciprocation of the platen depending on the detected length of the original. CONSTITUTION:The feed-direction length (size) of an original conveyed from an original feeder to a platen 3 is detected by an original sensor 83 and a timer to control the length of reciprocation of the platen depending on the detected length of the original. At that time, the length of reciprocation of the platen 3 is increased or decreased to a necessary value depending on the detected size of the original. The useless operation time of the platen 3 is thus eliminated to shorten the processing cycle time of the original. After the platen 3 is moved forth as shown at (a), the platen is immediately moved back as shown at (b). The original already exposed to light is conveyed along with the backward motion of the platen 3 as the original is pushed by a conveyor roller 56.

Abstract: PURPOSE:To improve the electrostatic breakdown withstand voltage of a semiconductor device without using a specific protecting device and without remarkably increasing a margin between the steps by forming an impurity diffused region and electrode holes in polygonal or circular-arc shape. CONSTITUTION:When an electrode hole is formed in a square shaped, parts where electrostatic pulse electric field becomes strong are produced at four corners A, B, C, D of the electrode hole 5 so that the alloying of the silicon is accelerated. Accordingly, the hole 5 is, for example, fored in a circular shape 25, and to avoid the concentration of the electric field due to electrostatic pulse applied between a resistor 14 and an epitaxial layer 13, a resistace electrode diffused region is formed in a circular-arc shape. Then, the withstand voltage against static electricity can be largely improved. When a polygonal shape having at least an inner angle exceeding 90 deg. such as an octagonal shape is employed, the equivalent effect can be obtained.

Filed: 1986-04-15
Abstract: PURPOSE:To enable a damping value to be set freely by causing a generator to be driven in a rotational motion varied in its vibration amplitude so that the vibrational energy is absorbed by applying load to the generator, and then varying the load applied to or the field current streamed into the generator. CONSTITUTION:The relative displacement between a vibrational body 2 and an additional mass 4 is converted into a rotational motion by means of a translation-rotation converter, and moreover, it is accelerated by means of a transmission so as to cause a generator 10 to be operated. Hereupon, the kinetic energy is converted into electricity, and the energy is absorbed after it is converted into heat and the like by means of a resistor 12 added to the generator 10. That is, at this point, the damping effect can be adjusted by way of varying the resistance value of the resistor 12. Thereby, the damping factor can easily be changed by way of either varying the acceleration factor by means of a transmission or varying the resistance value of a resistor.

Abstract: PURPOSE:To prolong the time constant of peak values by feeding the output signal of a peak detector back to the inversion input end of a differential amplifier and making the feedback ratio thereof equal to the inverse number of the non-feedback gain from the non-inversion input end of the differential amplifier up to the input end of a comparator. CONSTITUTION:Light signal received in a photo detector 11 is fetched out as an electric signal which is then converted to voltage by a load resistance RL. This voltage is applied to the non-inversion input end of a differential amplifier 12. The output signal thereof is applied to the non-inversion input end of a comparator 13, where it is subjected to level comparison with a reference input Eref. The peak detector 14 constituted by a series circuit of a diode Dp and capacitor Cp detects the output peak value of the amplifier 12 and feeds it back to the inversion input end of the amplifier 12 via feedback circuit 15 consisting of resistances R1, R2. The feedback ratio of the feedback circuit 15 is set approximately equal to the inverse number of the non-feedback gain from the non-inversion input end of the amplifier 12 up to the non-inversion input end of the comparator 13. In this way, the light signal receiver of the prolonged holding time constant of peak values may be obtained.
