Title: Combine
Inventor: KAWASE MUNEYUKI
IPC: A01D61/00
Filed: 1987-09-25
Abstract: PURPOSE:To improve accuracy of precision of threshing operation, by setting a delay time changing means to increases or decrease delay time of change of grain stalk holding position in a control means for handling depth depending upon amount of movement of reaping part by a side sliding mechanism. CONSTITUTION:A volume VR detects amount of rotation of a motor M2 and corresponds to the side sliding amount of a reaping part 23. A timer T checks the on/off state of an ear tip sensor and then clocks delay time up to drive of the motor M2. Since the output of the volume VR is proportional to amount of movement of the reaping part 23 in the direction of an arrow A, clocked time is reduced as the reaping part is transferred in the direction A. When the timer T is timed up, a motor M1 is driven and a grain stalk holding position is changed.

IPC: C08L23/00
Filed: 1994-10-06
Abstract: PURPOSE: To suppress water tree formation in an insulating body by mixing a specified range of parts by weight of polyethylene polymerized while using a single site catalyst and having a specified density and MI and a specified range of parts by weight of high pressure polymerized polyethylene with a specified density. CONSTITUTION: Polyethylene having 0.910-0.945g/cm<3> density and 0.5-5.0g/10min MI is produced by polymerization while using a single site catalyst having uniform active sites and a structure in which transition metals (Ti, Zr) are sandwiched by unsaturated cyclic compounds. Also polyethylene having 0.910-0.945g/cm<3> is produced by high pressure radical polymerization. Both polyethylenes are mixed in a range from (95:5) to (50:50) by weight ratio (the former: the latter) to give an electric insulating/composition. Together with semiconductive layers 2, 4, an insulating layer 3 is formed on a conductor 1 to give an electric wire/cable. The polyethylenes have high strength in amorphous parts and suppress the progress of water tree formation.

Filed: 1984-11-16
Abstract: PURPOSE:To improve a branch ratio and to reduce a switch voltage by providing a thin film waveguide lens consisting of electrooptic materials instead of a crossing waveguide which is the cause of the degradation of the branch ratio. CONSTITUTION:Respective end parts of input waveguides 4a and 4b and output waveguides 5a and 5b are so arranged that they are in focusing relations optically by a waveguide lens 11 consisting of a PLZT thin film, and control electrodes 3 are arranged on them through buffer layers 14.
