Title: Color ink jet recording device
Inventor: FUKUI HIROSHI
IPC: B41J2/01
Filed: 1989-11-02
Abstract: PURPOSE:To obtain an images with a high picture quality and high grade even when a recording medium is a special purpose paper such as an OHP paper, etc., by a method wherein for an information which is related with a color which is formed by compounding inks with different colors, inks are respective used for one time, and for an information for which a single color ink is sole used, recording is performed by lapping over the ink for several times. CONSTITUTION:A discrimination information which shows that a recording medium is an OHP paper, etc., is input by a DIP switch 33 or an operation key 16. For dots which are formed by using Y, M, C or Bk solely, since a dot diameter becomes small by one time of recording in the case of OHP paper, repeated recordings for two times are performed, and as the result, a sufficient dot diameter can be obtained. In the meantime, for dots which are related to a color which is formed by mixing either two of Y, M or C such as R, G, or B, since the ink quantity becomes sufficiently large even by one recording, only one time of recording is performed.

Title: Production of circuit device having dielectric resonator
Inventor: IMAIZUMI TATSUYA
IPC: H01P1/205
Filed: 1992-09-30
Abstract: PURPOSE:To prevent the deterioration of characteristic of a dielectric resonator and also to reduce the cost of the resonator by applying simultaneously the baking treatments to the conductive paste applied layers of a cylindrical porcelain dielectric and a porcelain substrate. CONSTITUTION:The conductive paste applied layers of the dielectric resonators 1 and 2 and the conductive paste applied layer of a porcelain substrate 3 are baked at one time. In this baking treatment, a contact is secured between both layers and therefore these layers are joined together. Thus both resonators 1 and 2 are fixed to the substrate 3 and no soldering process is required. As a result, the production process of a circuit device having the dielectric resonators can be simplified and the production cost the device is reduced. Furthermore the outer conductor layers of both resonators 1 and 2 are never bit by the solder owing to no use of the solder. The heating process is not required either for the soldering and therefore the cracks of both inner and outer conductor layers can be decreased. Then both layers can be simultaneously joined to the substrate 3.

Thus, a thermal transfer recording medium is so constructed as to have a resin ink recording layer with a releasable layer mainly composed of the wax. In this manner, with use of the ink which exhibits an adhesion relatively easily in the application of a thermal energy with no possibility of melting to be a low-viscosity material and contains a resin having some mechanical strength as a main component, the transfer is carried out so that the ink adheres to the projected parts of the surface of a transfer paper inferior in surface smoothness and covers the recessed parts thereof. Therefore, a printing can be conducted with high quality.
