IPC: B41J2/38
Filed: 1986-02-12
Abstract: PURPOSE:To make it possible to shorten a transferring time and enhance printing speed, by providing a preheating means for heating an ink ribbon prior to printing. CONSTITUTION:A printing head part 1 is provided with printing electrodes 2 and a preheating electrode 3 for preheating an ink ribbon 4.

Inventor: NAKAJIMA ICHIRO
IPC: E04D12/00
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To improve workability and a function by sticking a waterproof moisture permeable sheet passing no waterdrop and passing moisture to at least one surface of a synthetic resin foaming body. SOLUTION: A heat insulating panel 1 is constituted by adhering a waterproof moisture permeable sheet to both surfaces of a rectangular solid-shaped synthetic resin foaming body so that damage at walking time on the panel is prevented by setting compressive strength of the foaming body not less than about 5 kg gf/cm<2> . Next, a slip at walking time on the panel is prevented by arranging a fine recess/ projection on the waterproof moisture permeable sheet on one side of the panel 1. Then, a part of the waterproof moisture permeable sheet is projected to the outside of the foaming body to be adhered in layers to an adjacent panel 1 at execution work.  For example, at execution work of a roof, after fixing the panel to a sheathing roof board 14 or the like by a nail or the like by pressing down the panel 1 arranged on asphalt roofing 15 by a sash bar 16, a roof tile 17 is arranged on the panel 1 to be installed on the sash bar 16 by a nail. Therefore, since the foaming body and the waterproof moisture perameable sheet can be simultaneously executed, rainwater can be discharged outside as steam even if rainwater infiltrates into the sheathing roof board.

IPC: G01F23/292
Filed: 1991-02-25
Abstract: PURPOSE: To allow a liquid level to be measured by utilizing attenuation wave loss from an optic fiber caused from a border between the fiber and liquid. CONSTITUTION: An optic fiber 54 includes an inner fiber core and an outer fiber clad and extends to allow measurement of a wave quantity at the highest and the lowest levels of liquid. A light source 64 such as semiconductor laser injects light to a second terminal 60 of the fiber 54.

Therefore, the light energy passes through a fiber length twice. Light dctors 68, 70 measure a light intensity loss quantity with a current ratio I2 /I1 of the light detectors exponentially varying with a height of the liquid. The current I1 represents light intensity which has passed through the fiber twice.  A liquid level determination circuit 72 and a liquid level indicator 74 generate and indicate a strength loss signal indicating light intensity loss.
