Title: Non-slip pavement work
Inventor: OHASHI CHIAKI
IPC: E01C7/26
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To improve the function, by laying a paving layer in which a high- molecular resin and fine glass fragments are mixed together in advance, on a foundation bed for the paving and scattering milled fiber that fine glass fiber is ground, on the surface. SOLUTION: A high-molecular resin containing fine glass fragments is applied on a paving foundation bed 1 to form a paved layer 2. Then, milled fiber is scattered on the paved layer 2 in such an extent that the surface thereof is almost covered therewith to form a rugged surface 3 of the milled fiber. After curing of the resin, the non-combined milled fiber against the layer 2 without absorbing the resin is recovered. In this time, since milled fiber lumps scattered in an aggregated condition like pills owing to electrostatic forces are stuck to the surface of the layer 2 as the condition of the pills is kept, by the high- molecular resin absorbed owing to the capillary action or the like, the surface of the layer 3 gets appropriate for a non-slip effect.  In this way, damage of tires, shoes bottom, etc., or injuries or the like on falling can be prevented and also inexpensive materials can be used and the construction can be easily executed.

Title: Photomultiplier tube
Inventor: TAKEUCHI JIYUNICHI
IPC: H01J43/22
Filed: 1983-05-31
Abstract: PURPOSE:To reduce useless electrons modified of travelling direction through magnetic field not to reach to the dynode, by widening the anode and dynode fully to the side wall of an air-tight container thereby enlarging the area of them. CONSTITUTION:The meshed portion of anode 10 is surrounded by an outercircumference 10a slightly shorter than the innercircumference of an air-tight container 1. Four lugs 10b are projected from the outercircumference 10a to the meshed portion. A fixing hole 10c is made at each lug 10b. Since the area of anode and dynode is enlarged, the output will drop slowly under relatively low magnetic field such that it will be about 95% of initial level when the axial magnetic field has reached to 500 gause. It will drop further slowly even when the magnetic field has exceeded over 500 gause to reach to 78% of initial level for 10K gause where the dropping rate is smoothed.

Abstract: PURPOSE:To obtain sufficient airtightness even when a rotary bezel is rotated, by forming a knurling tool-like uneven section, whose level difference is smaller than the pressing width of an elastic sealing member, on the contacting surface of a barrel with the elastic sealing member and preventing partial extension of the sealing member. CONSTITUTION:An elastic sealing member 109 is put between a barrel 110 and rotary bezel 107 by pressing. The rotary bezel 107 is pressed into the barrel 110 and fixed to the barrel 110 by means of its engaging section 108. But the rotary bezel 107 can rotates under this condition. A bottom cap 113 is brought into close contact with and is fixed to the barrel 110 by pressing a packing 111. A movement 114 is fixed to a watch case by means of an intermediate frame 112. A knurling tool-like uneven section 201, whose level difference is smaller than the pressing width of the elastic sealing member 109, is formed on the surface of the barrel 110 contacting with the elastic sealing member. Therefore, the partial extension of the sealing member can be prevented by the strong frictional force between the rotary bezel 107 and sealing member 109 and the airtightness is never lowered even when the rotary bezel 107 is rotated.
