Title: Drive circuit of self-extinguishing element
Inventor: SHIRAISHI HIROTAKA
IPC: H02M1/06
Filed: 1984-10-29
Abstract: PURPOSE:To effectively prevent a self-extinguishing element from refiring by providing a diode reversely with respect to the parasitic diode of a power MOSFET using the reverse bias drive circuit of the self-extinguishing element. CONSTITUTION:The drive circuit 50 of a gate turn OFF thyristor (GTO)1 has a forward bias circuit composed of a forward bias DC power source P, a transistor 21, and a resistor 11, and a reverse bias circuit composed of a reverse bias DC power source N, a resistor 12, and a power MOSFET32. In this case, a diode 5 is connected in series with the MOSFET32 in the reverse direction to the diode 4 contained in the power MOSFET32. Thus, in order to interrupt the GTO1, when an OFF signal is supplied from a control signal generator 9, the transistor 21 is turned OFF to turn ON the MOSFET32, a reverse bias DC power source N is applied to the gate of the GTO1, and the diode 5 suppresses the excess positive gate current.

Title: Thermo-pervaporization apparatus
Inventor: KIMURA HISAFUMI
IPC: B01D61/36
Filed: 1983-11-30
Abstract: PURPOSE:To increase an available membrane area per unit volume while enhancing the permeation speed of vapor, by directly contacting a high temp. liquid and a low temp. liquid through the membrane wall of the membrane tube arranged in an outer tube. CONSTITUTION:A heated liquid is introduced into a liquid passage 3 and vapor generated from the high temp. liquid is transmitted through the wall of the membrane tube 2 provided in said passage 3 to reach the interior of the membrane tube 2 because the wall of said membrane tube 2 is impervious to the liquid but pervious to the vapor thereof and cooled by the low temp. liquid in the membrane tube 2 while the condensate is recovered in said low temp. liquid. The solute in the high temp. liquid is blocked by the wall of the membrane tube 2 along with the liquid and concentrated in the high temp. liquid. The porous membrane constituting the membrane tube 2 has no compatibility with the liquid contacted therewith and, therefore, in the case of an aqueous solution, a material having hydrophobicity and heat resistance such as polytetrafluoroethylene resin is pref. used.

Title: Production of single crystal structure and device for producing the same
Inventor: YAMAMOTO MICHIYOSHI
IPC: B22D27/04
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To easily produce a cylindrical single crystal structure. SOLUTION: A template 13 having a double cylindrical portion 14 and a double reversibly conical portion 17 is disposed in a heating oven 1 having a double cylindrical portion 2 and a double reversibly conical 5. A melted metal is poured into the template 13 whose inner and outer side walls are heated with the heating oven 1. The poured metal is singly and radially crystallized from the lower end portion of the double reversibly conical portion 17 toward the upper portion by the decrease in the heating quantity of the double reversibly conical portion 5. Subsequently, the double cylindrical portion 2 and the inner reversibly conical portion 7 of the heating oven 1 are upward moved to gradually bring the double cylindrical portion 14 into contact with outer air. The poured metal in the double cylindrical portion 14 is thus cooled and singly crystallized.  Since the inner and outer side walls of the template 13 can be heated in the double cylindrical portion 2 and the double reversibly conical portion 5, the temperature gradient of the poured metal between the inner and outer side walls can be controlled, and the poured metal can easily cylindrically be crystallized into the single crystal.

Title: Vibration-sensitive switch
Inventor: MORI HIDETAKA
IPC: H01H9/02
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To improve contact reliability of an opening/closing contact part by securing a base end part of an enclosing element or an extending element of a movable spring to a body and bringing the extending element of the movable spring in touch with a contact plate with a high contact pressure. SOLUTION: In a natural state, an extending element 62 of a movable spring 6 is pressed via a push button 5 because of a self weight of a spherical body 4 thereby to be in touch with a fixed contact 32. A pair of contact plates 31 are consequently connected via the movable spring 6, closing an opening/closing contact part 3. At this time, a base end part of an enclosing element of the movable spring 6 is secured to a body 2 by a thermal welding pin 23, and therefore a base end part of the extending element 62 is prevented from levitating. The extending element 62 is brought in touch with the fixed contact 32 of the other contact plate 31b while a high contact pressure is secured. Contact reliability of the contact part 3 is hence improved. When a quake is applied, the spherical body 4 rolls away from a lower end 11 of a base 1, opening the contact part 3.  The quake is accordingly sensed.

Title: Improved method for generation of multiple master font
Inventor: TORENSU ESU DOURINGU
IPC: G06T11/20
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To keep a satisfactory form from the viewpoint of beautiful appearance when a character style design characteristic is changed along a character style designing axis by displaying a character by use of a selected value of variable character style design characteristics and an established predefined character attribute. SOLUTION: The weight of W is changed only along one weight design axis. The weight is changed in an arrowed direction 40 along the weight design axis from a finest character 30 in the top to the thickest character 39 in the bottom. In this example, the weight is assumed to change from a relative weight of 10% (represented by the finest character 30) to 100% (represented by the thickest character 39). While the character weight is gradually increased from the character 30 through the characters 31-34, the design of character style is constant, and only the weight is linearly inserted to the inside or outside according to a conventional multiple master lettering technique. Thus, when the character design is changed with a weight of 60% or more, a more satisfactory character can be provided from a partial point of view.
