Title: Manufacture of multilayer circuit board
Inventor: ISHIKAWA KAZUMITSU
IPC: H05K3/46
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To mount in a high density by laminating copper foil layers via an insulating layer, etching it so that only electrodes are retained until insulating layer is exposed, and forming a plating layer on the entire surface of the insulating layer with the electrodes as the electrodes for electric plating, thereby facilitating microminaturization of a circuit. SOLUTION: Copper foils are laminated via an adhesive layer 10 on a board to form a copper foil layer, and the foil layer of a residual part 11b is removed by etching with only the foil layer of its periphery 11a is retained. In the case of electric plating the plating layer formed by using the periphery 11a as the electrodes is formed directly on an adhesive layer 10, without the intermediary of the foil layer. Thus, a height of an outer layer circuit 14a which is formed by etching becomes a height h1 of the plating layer. Accordingly, since a width W of the circuit 14a does not become narrowed by an etching removed part 20, microminiaturization of the circuit 14a is facilitated.

Title: Air flow amount control device of air conditioner
Inventor: SUGIYAMA TETSUO
IPC: F24F11/02
Filed: 1984-03-19
Abstract: PURPOSE:To prevent the draft from generating by a method wherein the generation of draft is detected from the difference between the mean temperatures at the ceiling portion and that at the floor portion of an air-conditioned room and, after the draft generates, a fan is controlled so as to rotate in the constant speed at the rotational frequency just before the generation of the draft and at the same time the rate of hot water flowing to a hot water coil is controlled. CONSTITUTION:The difference E between the mean temperature at the ceiling portion measured by a mean temperature sensor A18 and that at the floor portion measured by a mean temperature sensor B20 of an air-conditioned room 9 is detected by an adder-subtracter 21 and inputted to a limiter 22. When the limiter 22 outputs an ''ON'' signal due to the generation of darft, the make contact q5 of a contact q4 is shut-OFF, resulting in giving the output value of a temperature controller 15 as it had a certain period of time before from a sampling memory 26 to a variable voltage-variable frequency device 16 in order to control a fan 5 in the constant speed at the rotational frequency just before the generation of the draft. Further, the make contact q3 of contacts q1 and q2 is shut-OFF, resulting in giving the room temperature signal sent from a temperature sensor 14 to the temperature controller 25 in order to control the opening of a hot water control valve 3. In addition, a contact q6 is turned to make, resulting in starting a timer 24. Consequently, when the set time is over, the respective contacts q1- q7 are changed-over, resulting in controlling the rotational frequency of the fan.

Title: High polymer combined film
Inventor: FURUKAWA TAKEO
IPC: B32B27/20
Filed: 1988-03-07
Abstract: PURPOSE:To obtain a high polyer combined film having multiple functions in addition to an electrooptical effect and nonlinear optical effect by providing independent or continuous diffused phases in a high polymer. CONSTITUTION:Liquid crystal, dyestuffs, etc., are diffused into a porous high polymer film. Such high polymer composite film can be produced in such a way that the porous high polymer film is formed by evaporating the solvent from a high polymer solution containing, for example, water and alcohol and a diffused phase is formed by filling up the pores in the film with functional low molecules, such as liquid crystal, dyestuffs, etc. Moreover, the diffused phase is produced by uniformly diffusing the liquid crystal and dyestuffs into the high polymer matrix independently or in a state where they are mixed with each other and the diffused phase thus obtained is different from the uneven diffused system produced by well-known conventional costing methods. Therefore, electric characteristic such as dielectric constant and optical characteristics such as nonlinear optical effect, double refraction of this high polymer combined film are improved.

Title: Method for recovering solvent
Inventor: KOGA KUNIO
IPC: B01D53/44
Filed: 1989-03-07
Abstract: PURPOSE:To reduce the size of the device and the initial cost thereof by passing a dilute gaseous solvent under pressurization or atm. pressure through adsorption columns to execute adsorption and introducing steam under the pressure lower than the adsorption pressure or under the reduced pressure at a nearly equal temp. into the columns, thereby executing desorption. CONSTITUTION:Recovery of a solvent by a pressure swing from the dilute gaseous solvent such as acetone is executed. The dilute gaseous solvent is passed under the pressurization or the atm. pressure through the adsorption columns 2a, 2b and are subjected to the adsorption. The desorption is executed by introducing the steam under the pressure lower than the adsorption pressure or under the reduced pressure at a nearly equal temp. into the columns. Namely, the operations are nearly isothermal as compared to the adsorption method by the conventional thermal swing method and, therefore, the heat energy to be consumed for the heat capacity of the device and a packing material is eliminated and the substantial saving of energy is attained and at the same instant, the shorter adsorption/desorption cycles can be adopted. The smaller amt. of the adsorbent is consequently necessitated. As a result, the size and initial cost of the device are reduced.

IPC: H01J29/89
Filed: 1984-03-23
Abstract: PURPOSE:To compensate chromatic abberation, to improve the resolution and to improve the contrast by coloring a cooling liquid, which is sealed in the front of a cathode-ray tube, with one or more kinds of dye to prescribe transmittance characteristics and prescribing the product of transmittances. CONSTITUTION:A cooling liquid 5 is sealed between a front panel 11 of a cathode-ray tube body 1 and a front panel 3, and a cooling body 4 is provided. A lens 61 is adhered to the front of the panel 3 by an optical adhesive 7. With respect to the cooling medium 5, for example, yellow and blue dyes are used for a phosphor for green, and formulas (where TYS and TBS are spurious transmittances of yellow and blue dyes respectively and TY545 and TB545 are transmittances of yellow and blue dyes for 545nm wavelength respectively) are satisfied. Though a luminous flux L0 from a phosphor 2 is radiated ahead, a part of it is reflected on the exit of the lens 61 and is returned to the phosphor 21 to brighten the dark part of the phosphor. The similar processing is possible for phosphorus for red and blue. Thus, chromatic aberration is compensated to improve the resolution, and the contrast is improved also.
