Title: Color display device
Inventor: FUJITA MASANORI
IPC: G02F1/13
Filed: 1982-07-12
Abstract: PURPOSE:To realize clear display in bright color and to increase contrast by stacking an optical activator liquid-crystal layer which reflects light with specific wavelength in a visible region upon a display layer body capable of controlling a transparent mode and a scattering mode, and providing a specular surface reflecting plate on its back. CONSTITUTION:When the optical activator liquid-crystal layer 7 reflects light in green and transmits other wavelength purplish red light, incident light is transmitted through the display body layer 3 at a part A where the display body layer 3 is in transparent mode while only the green light is reflected by the layer 7. The transmitted light is reflected by the specular surface reflecting plate 8 and emitted out after passing through the layers 7 and 3 again. This part is seen in bright clear green from the front. Then, the incident light is scattered and reflected partially by the layer 3 at a part B where the layer 3 is in scattering mode, and the transmitted light has the green light reflected by the layer 7 and the transmitted light reflected by the plate 8 before being emitted out, but the quantity of the light is decreased. For example, when segment display is performed at the part A while the part B is used as a background part, characters, etc., are displayed in clear green on a slightly greenish white scattered background. The layer 3 uses liquid crystal of ferrodielectric transparent ceramic.

Title: Thermal head
Inventor: SHIRAISHI SADAZUMI
IPC: B41J2/335
Filed: 1990-05-10
Abstract: PURPOSE:To improve the cooling characteristic of a heat generating resistor by providing a heat control layer for controlling the heating/cooling characteristics of the heat generating resistor between a glaze layer and an insulating board for obtaining adequate thermal conductivity and film thickness of the heat control layer. CONSTITUTION:A part of Joule heat generated at a heat generating resistor by power is transmitted to a medium through a protective layer and a part of the heat is stored in a glaze layer which is a lower layer of the heat generating resistor. The heat stored in the glaze layer is radiated to a dimensional direction of a heat control layer having a thermal conductivity lambdah higher than a thermal conductivity lambdag of the glaze layer, a part of it is also radiated to an insulating board (thermal conductivity lambdas) through the heat control layer. A radiation effect to the dimensional direction of the heat control layer becomes conspicuous according as the thermal conductivity lambdah is made higher than the thermal conductivities lambdag and lambdas, so that the heat generating resistor can be cooled rapidly. Thus, the heat generating resistor can be maintained in a temperature capable of printing for only necessary time dependent on a specification by setting the thermal conductivity lambdah, film thickness, forming dimension of the heat control layer to adequate values.

Title: Ink jet printer
Inventor: DEGUCHI MASAAKI
IPC: B41J2/01
Filed: 1989-05-16
Abstract: PURPOSE:To prevent ink from sticking to the surface of a pressure member by providing a contact member of two-layer structure, one low coagulative adhesion layer which comes in contact with printing paper and the other hard layer between a pressure member and the paper. CONSTITUTION:Printing paper 36 is fed to an area between a platen 10 and a pressure roller 70 after being printed by an ink jet head 15. The ink droplet is of a cubic shape, and becomes cured as soon as it sticks to the paper 36 due to its low thermal capacity, then it becomes a semi-spheric ink mass 79. This ink mass 79 is flatly pressed by pressure applied by the lower synthetic hard resin layer 74a of a synthetic resin layer 74b when passing through an area between the platen 10 and the pressure roller 70, as the low coagulative adhesion synthetic resin layer 74b with which the ink mass comes in contact is thin and its deformation is insignificant. Subsequently ink does not stick to the contact surface 75.
