Title: Block copolymer, and its production and use
Inventor: SAEGUSA TAKEO
IPC: C09K23/52
Filed: 1984-04-26
Abstract: PURPOSE:To obtain a block copolymer having excellent surface activity, by completely conducting a first-stage cationic ring-opening polymerization of a 2- oxazoline compound in the presence of a specified polymerization initiator and conducting a second-stage cationic ring-opening polymerization of another specified 2-oxazoline compound in the same reaction system in a specified manner. CONSTITUTION:A first-stage cationic ring-opening polymerization of a 2-oxazoline compound of formula II (wherein R2 is H or the like) or a 2-oxazoline compound of formula III (wherein R3 is a 4-18C alkyl or the like) is completely conducted by using a 1:2 reaction product between a 2,2'-bisoxazoline compound of formula I (wherein Y is a 1-18C alkylene or the like) and a cation polymerization catalyst such as a sulfate or sulfonate ester. When the first-stage polymerization involves a compound of formula II, a second-stage cationic ring- opening polymerization involves a compound of formula III. When the first-stage polymerization involves a compound of formula III, the second-stage polymerization involves a compound of formula II. In this way, the purpose block copolymer can be obtained.

Abstract: PURPOSE:To make the flow rate regulating function of a water wheel unnecessary, by a method wherein the secondary current of a wound-rotor type induction generator is controlled in accordance with the signal of the product of a slip frequency and a voltage deviation with respect to a primary side voltage. CONSTITUTION:The output signal (fr) of a rotary phase detector 12, driven by an induction generator 8, and the signal (f1) of an oscillator 19, provided in order to specify the primary frequency (f1) of the induction generator 8, are compounded by a slip phase detector 13 to detect a slip frequency (f2). On the other hand, a voltage, induced in the primary winding of the induction generator 8, is compared with a set voltage and a difference between them is outputted. The difference signal is multiplied by the slip frequency (f2) by a multiplier 17 and a resultant value is outputted to a secondary current controller 18. The secondary current controller 18 controls an AC/DC converter 9 based on an input signal to change the secondary current of the induction generator 8 and control a primary voltage.

Title: Water-resistant resin composition soluble in aqueous surfactant solution
Inventor: ATAGO YASUHIKO
IPC: G03F7/11
Filed: 1991-03-27
Abstract: PURPOSE:To provide the title compsn. which is sufficiently water-resistant under normal conditions whereas it can be dissolved or peeled off without using an aq. alkali or acid soln.

Title: Aerodynamic window
Inventor: YUNGUAN SHIEN
IPC: H01S3/034
Filed: 1990-03-29
Abstract: PURPOSE: To improve the quality of light by providing the suction chamber of a differential pump between the other end section of a light passage and a light-emitting hole and making the operating pressure of the differential pump nearly equal to the pressure at the other end section of the light passage on the suction chamber side. CONSTITUTION: The laser chamber-side end section 13 of a light passage 14 faces oppositely to a suction chamber-side end section 20 of the passage 14 on a straight line, and the end section 20 shifts to a suction chamber 21 of a differential pump. The pressure in an active chamber 11 is adjusted to, for example, 100mbar, and the chamber 11 must be sealed from the atmospheric pressure of about 1,000mbar. The sealing is performed at a gas-flow window 16 and compressed air is pressed into a nozzle passage 15 of the window 16 with a pressure of, for example, 3.8bar, and the passage 15 is raised roughly to the atmospheric pressure at an exit 37 of the passage 15. Since the operating pressure in the suction chamber 21 is about 600mbar, the window 16 can be designed to seal a differential pressure of about 500mbar.  This differential pressure is smaller than that of the conventional gas flow window, and the volume of the gas flowing through the window can be suppressed to a small value.

Title: Image display tube
Inventor: HAYASHI NOBUAKI
IPC: H01J29/89
Filed: 1989-04-10
Abstract: PURPOSE:To improve the utility of light so as to obtain a bright and high quality image by constructing the face plate of a display tube with a glass layer of normal refractive index and a layer formed like a convex lens of high refractive index and a layer of low refractive index provided on the surface. CONSTITUTION:The light from a luminous point 3 levels in vacuum or phosphor to reach the surface of a transparent material layer 7 of low refractive index. The reflectance at the interface of the transparent material layer 7 is lower the lower the refractive index of the said layer 7, and larger amount of light can be transmitted in the layer 7. The light transmitted through the layer 7 travels to the glass layer 1 from a transparent material layer 6 of high refractive index, and as the refractive index of the layer 6 is higher than that of the glass layer, the incident angle of the light on the surface of the glass layer 1 can be decreased, and the light can be emitted in the air without generation of total reflection not like a light beam 9 in a conventional structure. And also in the case of light of an incident angle generating no total reflection like a light beam 10, the angle of refraction at the outer surface of the face plate can be made smaller than that in the conventional structure, thus larger amount of light can be transmitted to eyes of observers.
