Title: Thermo-sensitive recording paper
Inventor: HONDA YASUHIRO
IPC: B41M5/337
Filed: 1981-07-11
Abstract: PURPOSE:To obtain the thermo-sensitive recording paper, the density of foundation thereof is low, fog thereof is little, climate-resisting property thereof is excellent and which resists water, chemicals, heat, etc., by size-treating a papery substrate by resol type phenol resin and forming a thermo-sensitive color-forming layer containing leuco dyestuffs to the substrate. CONSTITUTION:The thermo-sensitive color-forming layer using the leuco dyestuffs as a color-forming component is shaped onto the surface of the papery substrate. Paper manufactured by natural fibers or synthetic fibers, basis weight thereof is normally 30-200g/m<2>, applies as the papery substrate employed. The resol type phenol resin is carried to the papery substrate through a conventional common sizing method. Since the resin has a function which reacts with the leuco dyestuffs in the thermo-sensitive color-forming layer formed onto the substrate when heating and color-forms the leuco dyestuffs, an acidic substance as a developer need not be made contain particularly in the thermo-sensitive color-forming layer, the quantity can be decreased when the acidic substance is made contain, and the recording paper has an advantage of which the fog of a liquid is little even when using an extender.

IPC: B62D33/023
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To facilitate the retightening of connecting bolts and prevent backlash of the sections assembled to the gate and side panel. SOLUTION: In a gate or side panel in which an upper level section 1u, a middle level section 1m, and a lower level section 1d are connected with a connecting bolt 4, a leg portion of the connecting bolt 4 is screwed into a nut 5 fixed to a washer 8 that restricts rotation at the inner wall surface of the lower level section 1d.

Title: Gas cutoff valve
Inventor: SUGIYAMA MASAKI
IPC: F16K31/06
Filed: 1993-05-11
Abstract: PURPOSE:To shorten a projecting length to a main passage while offsetting a spring bearing and a sub-spring to each other, and restrain these from becoming an obstacle to gas in the main passage by arranging a contact part with the sub-spring of a main valve in a recessed shape inside of the main valve. CONSTITUTION:When an electric current is carried to a coil 1, a plunger 3 is attracted to an attracting-piece 2. As a result, a sub-spring 16 is compressed, and a sub-valve 9 is separated from a sub-valve seat 12, so that a sub passage 14 is opened. When gas is flowed in from the sub-passage 14, differential pressure by which a main valve 12 is brought into pressure contact with a main valve seat 13 is reduced. Since energizing force of a main spring 15 is reduced more than energizing force of a sub-spring 16, the main valve 12 is separated from the main valve seat 13. The main valve 12 is self-held, and a main passage S is opened. By the way, a contact part with the sub spring 16 of the main valve 12 is formed in a recessed shape inside of the main valve 12. Thereby, the sub-spring 16 and this spring bearing 11 are offset to each other, and a projecting quantity of these to the main passage S is reduced.

Filed: 1978-09-06
Abstract: PURPOSE: To seal firmly without being influenced by the roughness or the flows of the rim by filling the rim split part with the annular rubber elastic body which has adhesiveness or viscosity to the rim.  
     CONSTITUTION: The annular rubber elastic body 9 which is adhesive or viscous to the rims 1, 2 is filled between the rims 1, 2. As the fitted and adhered rubber elastic body 9 seals the rims 1, 2 firmly at the charged position, there is almost no fear for the leakage of the air in the tire thorough the charged position. If the surface of the rim of the position of the rubber elastic body 9 is rough or has the flaws, not only the rubber elastic body such as the normal temperature hardening type silicone rubber penetrates into the rough part or the flaws to firmly prevent the leak of the air, the adhering area of the rubber elastic body 9 to the rims 1, 2 is increased to improve the adhering intensity.

IPC: B41J2/355
Filed: 1981-07-15
Abstract: PURPOSE:To suppress the maximum temperature of the thermo-sensitive head while keeping a sudden temperature rise and a sufficient color-forming temperature, and to lengthen life by dividing printing drive pulse corresponding to one dot into a plurality of pulses and supplying them to the thermo-sensitive head. CONSTITUTION:In the thermo-sensitive head consisting of a plurality of thermo- sensitive elements, the printing drive pulse corresponding to one dot is divided into a plurality of pulses and supplied to the thermo-sensitive head. The pulse such as the drive pulse P3 having high crest value is applied to the thermo-sensitive element fot time t1, and the temperature T3 of the thermo-sensitive element is suddenly elevated. The drive pulse P3 is at OFF and the temperature is lowered when the temperature T3 of the thermo-sensitive element sufficiently succeeds the color-forming temperature T0, and the drive pulse P3 is applied for time t2 again and the temperature is elevated just before the temperature of the thermo-sensitive element drops reaches less than the color-forming temperature T0. The color-forming temperature T0 is kept for a fixed time through such intermittent operation, and printing corresponding to one dot is completed, thus suppressing the excessive heat generation of the thermo-sensitive elements.

After the spectrum is acquired in this state, the shutter 4 is moved and the spectrum is acquired at the lower-half region of the detector 3.  By moving the shutter 4 and changing the relative position of the light reception surface of the detector 3, a peak by the diffraction X rays and the fluorescent X rays can be discriminated, thus eliminating the diffraction X-ray peak and analyzing fluorescent X rays qualitatively and quantitatively without being affected by the diffraction X ray peak.
