Title: Igniter for high voltage thyristor
Inventor: YAMAMOTO HIROSHI
IPC: H03K17/78
Filed: 1989-05-24
Abstract: PURPOSE:To reduce the size and power consumption by providing specific current limiting element, optical switching element and optical transmission means. CONSTITUTION:A light emission diode PD is brought into light emitting state through a DC power source B and an optical ignition signal is transmitted through an optical fiber 17 to an optical transistor PTR. Consequently, current flowing from the anode of a thyristor 3 to a resistor 14 bypasses the optical transistor PTR and does not go to the gate of the thyristor 3 which thus maintains OFF state. When a switch SW is turned OFF, output from the light emission diode PD goes to zero thus turning the optical transistor PTR OFF, and thereby the current flowing through the resistor 14 flows to the gate of the thyristor 3 through a diode D2. When this current exceeds over the ignitable current level of the thyristor 3, the current functions as the ignition current and turns the thyristor 3 ON.

Title: Packed tower
Inventor: NAKAMOTO HIDEKAZU
IPC: B01D53/18
Filed: 1985-06-19
Abstract: PURPOSE:To increase the specific surface area of a packing material and to enhance the efficiency of mass exchange, by laminating several fabrics each prepared by using a thread so as to have a mesh and packing the spaces of the laminated article with a packing material wherein strip like materials are arranged in an axial direction. CONSTITUTION:A plurality of fibers absorbing no liquid are bundled to form a thread which is, in turn, used to prepare a fabric having meshes and several fabrics are laminated to form a laminated article 4. The laminated article 4 is wound, for example, in a columnar shape and thin plates 5 are inserted in the laminated article 4. A liquid is fallen on the upper surface of thus formed packing material to enter the interior of the packing material and flows between threads by a capillary phenomenon. A part of the flowing liquid is contacted with the wall of each thin plate 5 to be guided to the side opposite to the wall surface. By this method, because the offset flow of a fluid is prevented and the specific surface area of the packing material increases, the lowering of efficiency is prevented even if the diameter of a packed tower becomes large.
