Patent JP-S60126589-A (JP)
Title: Heat exchanger
Inventor: KABURAGI KATSUHIKO
IPC: F28F13/00
Filed: 1983-12-12
Abstract: PURPOSE:To enhance the heat exchanging effciciency by providing a permeable solid wall which allows the passage of a fluid in a fluid passage outside and between heat conducting pipes so that the heat transfer by convection as well as heat transfer by radiation may be utilized. CONSTITUTION:In the passage of fluid between the outside heat conducting pipes 2, 2, a permeable solid wall 8 which allows the passage of said fluid is provided. For the solid wall, a porus flat plate such as ceramic honeycomb, punched metal or ceramic foam is suitable through a latticed plate will also do. The low-temperature air for burning blown by a blower enters from a heat exchanger inlet 1, directed downward along a stack of heat conducting pipes 2, passes through a connecting pipe 4, again passes through the heat conducting pipe stack to be heated and is discharged from a heat exchanger outlet 5 to be used as burning air for a furnace burner. Meanwhile, the high-temperature burnt exhaust gas discharged from the furnace flows from the upstream side 6 of a smoke duct to the downstream side 7, and a heat transfer takes place by convection in proportion to the speed of its flow. The solid wall 8 which has been heated by the passage of the high-temperature exhaust gas radiates the radiation heat to the heat conducting pipes 2, 2, and since the heat transfer by the radiation to the heat conducting pipes 2, 2 takes place in addition to the heat transfer by convection, the heat exchanging efficiency is significantly improved.

Title: After-image canceling circuit of liquid crystal display device
Inventor: KIDO KOICHI
IPC: H04N5/66
Filed: 1989-09-11
Abstract: PURPOSE:To obtain an excellent reproduced image whose after-image is canceled at the time of the rising response and falling response of liquid crystal by adding a deformed difference signal, obtained by varying a difference signal which is at an interval of one frame or field period to an input video signal, in specific different variation mode. CONSTITUTION:A coefficient circuit 5 generates the difference signal of the video signal which is at the interval of the one frame or field period of the video signal displayed by a liquid crystal display element using a liquid crystal element which performs display operation in twisted nematic electric field effect mode. A coefficient circuit 6 obtains the deformed difference signal by varying the difference signal in different mode corresponding to the rising response due to variation from the no- electric field state of the liquid crystal of the liquid crystal display element to an electric field applied state and the falling response due to variation from the state wherein the liquid crystal of the liquid crystal display element is applied with an electric field to the no-electric-field state. An adder 7 adds the deformed difference signal to the input video signal and outputs the resulting signal. Consequently, the excellent reproduced image whose after-image is canceled is obtained at the time of both the rising response and falling response of the liquid crystal.

Title: Optical waveguide
Inventor: WAIDE TATSUKI
IPC: G02B7/18
Filed: 1989-09-12
Abstract: PURPOSE:To shorten the length of the optical waveguide and to reduce the size of an optical head by providing a reflecting surface which reflects light radiated by a tapered waveguide layer toward a substrate. CONSTITUTION:Luminous flux emitted by a semiconductor laser 1 into the waveguide layer 3 is collimated by a collimator lens 4 into parallel light, which is bent by 90 deg. through a beam splitter 7 and converged by a waveguide lens 8a, so that the converged light is propagated in the waveguide layer 3. Then the light which is propagated in this waveguide layer 3 is radiated toward the glass substrate 9 by a tapered coupler 10 from the waveguide layer 3. This radiated light is reflected by the reflecting surface of a reflecting plate 5 provided on a substrate end surface and propagated in the substrate 9 to reach the other substrate end. This luminous flux is reflected by the substrate end surface, projected from the reverse surface side of the substrate 9, converged by an objective 11 arranged in its projection direction, and converged on an optical disk 12 to form a light spot. Consequently, the overall length of the optical head can be shortened and the structure is reduced in size.
