Title: Bar rack of bar rotation type screen
Inventor: UCHIDA NORIKAZU
IPC: E02B5/08
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To easily remove refuse under water by making a bar rack forming the vertical lengthwise slit-like filtering part of a basket a wedge shape making an acute angle toward the outflow side from the inflow side. SOLUTION: A carrier chain 4 is rotated by the rotation drive of an upper sprocket 3 to rotate a basket 5, and refuse is scooped up. Next, the refuse is filtered by a slit-like filtering part formed by a bar rack 10 to be caught, the basket 5 is inverted by the upper sprocket 3, and the refuse is naturally fallen in a refuse trough 7 to be collected. Pressure water is jetted from a spray nozzle 9 to remove the refuse. In this case, the bar rack 10 is made a wedge shape making an acute angle toward the outflow side from the inflow side. Thus, the pressure loss of flowing water passing the slit of the slit-like filtering part is small, the refuse is difficult to be stuck in the form of a wedge, and the biting-into refuse can be removed by pressure water.

The pressurizing cylinders 22 on both sides are advanced so that the mandrel part 28 is pressurized and inserted into the pipe by a pushing die 26. The upper die 12 having a guide groove 16 is placed thereon and is pressed toward the lower dies. The split dies 14A, 14B of the lower dies 14 are opened toward both sides to bend the pipe 10. Compressive force is exerted to the pipe wall on the side outer than the neutral axis of the pipe 10 to prevent the generation of elongation on the outside of the bent part. The pipe is pressurized by the actuation of the cylinders 22 in synchronization with the bending in the supporting step parts at the pipe end faces which are provided to the die 26 and are oblique with the pipe axial center. The pipe is thereby formed to the circular shape without decreasing the wall thickness on the outside of the bent part and without flattening the section of the bent part.

Abstract: PURPOSE:To provide an afterfoaming aerosol pack stock causing no foaming in its delivery, good in application feel, ready to remove by water and also giving warm feel, containing clay mineral(s). CONSTITUTION:The objective pack stock containing >=0.1wt.% (pref. 0.1 to 3.0) wt.% of at least one kind of clay mineral selected from montmorillonite, bentonite, hectorite and caolinite, etc. As a foaming agent, 2 to 7wt.%, based on the whole amount of the final pack stock, of propane, 1-butane or CFC-11 is used, being put into a specific vessel separated from that for a propellent and subjected to agitation mixing to obtain the objective product. Afterfoaming means that, when the present pack stock is delivered under static atmospheric conditions at 20 deg.C from an aerosol can, no foaming can virtually observed with the naked eye and white foams are gradually developed in >=30sec. When the present pack stock is applied on the skin, the vaporization of the foaming agent will become earlier due to the skin temperature, thus effecting gradual foaming.

Title: Charge transfer device
Inventor: MIWATA KAZUO
IPC: G11C27/04
Filed: 1990-05-14
Abstract: PURPOSE:To reduce the level of a reset feedthrough noise and to ensure a sufficiently high S/N ratio by a method wherein the reset feedthrough noise which appears at a floating diffusion operation is reduced or canceled at a source follower which detects a potential change in the floating diffusion operation. CONSTITUTION:It is assumed that a reset pulse phiR is at a high level. A reset feedthrough which has been synchronized with the phiR appears at an input voltage VP; and during this period, a MOS Tr Q6 is conductive, and the operating point of a source follower at an initial stage is the point (1) on a curve B. Then, when the reset pulse phiR is at a low level and the MOS Tr Q6 is set to an OFF state, the operating point is moved to the section (2)-(3) on the curve A. Only when the reset pulse phiR is at the high level, an offset voltage is dropped. As a result, the component of a reset feedthrough noise DELTAphiR appearing at an output voltage V2 can be made low as compared with that of the input voltage VP appearing at a charge injection point.

Title: Manufacture of self-tightening double-wall tube
Inventor: YOSHIDA TOSHIO
IPC: B21D39/04
Filed: 1981-08-10
Abstract: PURPOSE:To give a high radial fitting force without axial misalignments by expanding a inner and outer tube hydraulically and by keeping impression of expanding hydraulic pressure at the same time as stoppage of tube expanding at a set diameter in order to minimize the temperature difference between the inner and outer tube prior to removal of the tube expanding hydraulic pressure. CONSTITUTION:A carbon steel outer tube 1 is previously heated to a set temperature to enlarge the tube diameter, while a stainless steel inner tube 2 is cooled with service water to shrink the tube diameter, and to be inserted into the tube 1 for superposing, and service water 4 is introduced into the inside of the tube 2 through seal plugs 3 and 3, to apply a pressure to expand the tubes. The inner tube 2 is enlarged in its diameter and is plastically deformed to form one body together with the outer tube 1 and further the tube 1 and 2 are enlarged in their diameters to reach set diameters, and then keep the pressure to wait until the temperature difference between the tube 1 and 2 becomes small. When the temperature of the outer tube 1 starts to decrease, the face pressure between the tube 1 and 2 which already exceeds a limit friction surface pressure against the tube 2 sufficiently, is generated and also no axial misalignments are caused. After a prescribed duration of time, the service water 4 is removed. A double-wall self-tightened tube having high fitting force is produced by the shrunk diameter of the tube 1 and the enlarged diameter of the tube 2 caused when the temperatures of the tubes are reduced to the atmospheric temperature.
