Title: Fixing roller
Inventor: ARAI ATSUSHI
IPC: G03G15/20
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To give the relation of roller thickness and concaved amount securing the carrying property and the fixation of a thin fixing roller to the fixing roller. SOLUTION: When the thickness of the end parts of the concaved-surface fixing roller 1 is defined as (t) and the concaved amount (D0 -D1 ) is defined as σ, they are regulated so as to be the relation of (t)<=0.8(mm) and a <=0.1×t(mm). Thus, the difference of the thickness between the central part and the end parts of the roller 1 can be suppressed to be 5%. As the result, the variance of the fixation is reduced and the stable carrying property is obtained. Simultaneously, the required concaved amount is secured so that the excellent carrying property including the prevention of wrinkle is maintained.

Title: Trench excavator
Inventor: YAMASHIRO YOSHIHIRO
IPC: E02F5/04
Filed: 1980-04-11
Abstract: PURPOSE: To reduce a forward resistance with a hole made prior to the excavation by mounting a drilling unit on the lower end of an oscillating arm oscillating longitudinally at the rear position in a screw trench excavator in such a manner as to project from a screw excavator.  
     CONSTITUTION: Power is transmitted to a power intake shaft 6 through a universal joint 18 from a PTO shaft of a tractor 1 to drive rotary parts turning a lift arm downward. A trench is excavated with a screw excavating section 8 reaching a specified depth. After the lift arm is fixed to retain the trench at the specified depth, as the tractor 1 advances, earth excavated is carried upward sequentially with the screw excavating section 8 being gathered and guided with a earth gathering plate 9. When a drilling body 13 for digging the trench moves forward, it projects from the screw excavating section 8 and excavates at the lower end of the trench preceding the screw excavating section 8.

Title: Method and facilities for ventilating building with arranged heat generation facilities
Inventor: IIDA YUJI
IPC: F24F7/06
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To inexpensively and efficiently secure rising flow in each floor by quickening the rising of a heat air current around the periphery of each of heat generation facilities for exhaust. SOLUTION: Supplied outdoor air is blown from the lower part of a working floor 8 around heat generation facilities. In this case, it is especially important to set the blow-off direction upward in a range from a vertical direction to 45 degrees to the side of the heat generation facilities, thus cooling a heat airflow being generated by radiation heat around the heat generation facilities by outdoor air being supplied from an air-supply duct 10 of a lower part and at the same time smoothly raising the heat airflow without blocking the rising of the heat airflow with slightly low temperature as compared with other parts. The blow-off direction of the supplied outdoor air is preferably set to a range from a perpendicular direction to 45 degrees toward the side of the heat generation facilities.  When the blow-off direction of the supplied outdoor air is less than 45 degrees, the diffusion residence of the heat airflow can be easily generated, the smooth rising of the heat airflow is blocked, and ventilation efficiency is reduced.

Abstract: PURPOSE:To reduce the diameter of a beam formed during the time of a high current by making the size of the electron discharging surface of a cathode smaller than that of the electron-beam passing hole of a first grid electrode, and making the voltages of the first grid electrode and a second grid electrode to be positive and negative to the voltage of the cathode, respectively. CONSTITUTION:The size of an electron discharging surface 211 of a cathode 21 is restricted so that the diameter of the surface 211 is smaller than that of an electron-beam passing hole of a first grid electrode 22. The voltage of the first grid electrode 22 is made positive to that of the cathode 21, and the voltage of a second grid electrode 23 is made negative to that of the cathode 21. Here, a cross over 25, since it is formed in the space between the second grid electrode 23 and a third grid electrode 26, has a decreased extension, and has a reduced influence of space-charge effect. In addition, an equipotential surface 33 of the front electric field of the cathode 21 becomes flat, and the current density is increased. Consequently, increase of the diameter of a beam spot formed on a fluorescent screen, which is caused during the time of a large current, can be suppressed.
