Title: Material to be recorded reproducing device
Inventor: YAMADA MASAAKI
IPC: B41J29/38
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a material to be recorded reproducing device capable of reducing or preventing the partial chipping of the backup member of a cleaning device, in a material to be recorded reproducing device provided with a peeling device and the cleaning device. SOLUTION: When a broken hole 22a is made in a peeling belt 22, because of its long-term abrasive contact with a cleaning roller 41, a conductive edge 41a and the conductive elastic body 27a of the surface of a backup roller come into contact with each other in the part of the broken hole 22a, so that that a current lows through the edge 41a. The current after flowing through the edge 41a is grounded through a brush contact 41 and a bridge circuit EC1 in a broken hole detecting device 90. Simultaneously with this, when the current flows through the bridge circuit EC1, this signal is amplified in an amplifier EC2 and transmitted to a control part 100, as a broken hole detecting signal. When the control part 100 receives the broken hole detecting signal, a motor is stopped to stop the cleaning roller 41 and a driving roller.

Title: Two-piece can made of surface treated steel sheet and its manufacture
Inventor: NOGUCHI MASATOSHI
IPC: B65D8/00
Filed: 1988-12-23
Abstract: PURPOSE:To permit the application of surface treating method excellent in anti-corrosion performance by partially plating at least the ground contact part of a can made of steel plate with a tin-zinc alloy containing a specific amount of the zinc. CONSTITUTION:The surface of the ground contact part 10 of two-piece can 1 made of surface treated steel sheet is partially plated with a tin-zinc alloy containing a 2 - 20wt.% zinc. The plating with the tin alone, in the case of exposed steel surface due to the damage to the plated surface, will not protect the steel from the corrosive effect of such damage at the sacrifice of the tin, eventually resulting in the corrosion of the steel. The application of the anti- corrosion method in the increased amount of the tin is uneconomical with a reduction in the operational efficiency due to a longer plating time required. On the other hand, the plating with the zinc alone, although capable of protecting the steel against corrosion at the sacrifice of the zinc, elutes the zinc abnormally in a short time due to a large potential difference between the iron and zinc and, therefore, a long serviceability cannot be expected. The zinc is also liable to white corrosion with unsightly finish appearance.

Title: Hydraulic circuit
Inventor: NUNOTANI SADAO
IPC: F15B11/00
Filed: 1989-12-18
Abstract: PURPOSE:To improve responsiveness of volume control and facilitate processing by connecting a detecting pipe passage which is connected to an output side of a changeover valve in respect to a pressure receiving part of an operational valve through a shuttle valve, to one of a pressure receiving part of a volume control valve through a solenoid proportional pressure reducing valve to be controlled by a controller, and connecting the other pressure receiving part to a discharge passage of a variable volume pump. CONSTITUTION:Ports 9, 10 of a pilot pressure changeover valve 7 which is provided on a discharge passage 8a of an auxiliary pump 6 are connected to pressure receiving parts 5, 5 of an operational valve 5. A detecting passage 14 which is connected to the passage 6a through a shuttle valve 13 is connected to a first pressure receiving part 15a of a volume control valve 15 through a solenoid proportional pressure reducing valve 16, while discharge pressure of a variable volume pump 1 is input to a second pressure receiving part 15b. Outlet pressure of the changeover valve 7 is input to a controller 17 through a pressure sensor 18, and electric supply to a solenoid 16a is controlled. It is therefore possible to improve responsiveness of volume control of a pump 1, and facilitate adjusting and processing of time matching between the responsiveness above and changeover responsiveness of the operational valve 5.

Title: Hydraulic circuit for hydraulic shovel
Inventor: HOSHI KOSHI
IPC: F15B21/04
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To suppress pressure loss and the heating of operating oil and improve the driving efficiency of hydraulic cylinders and the durability of a hydraulic machine by providing a return line of the hydraulic cylinders with a branch line, and discharging return oil to a tank through a control valve. SOLUTION: A line 2f branches off from a return line 2e from a bottom chamber (a), and a control valve 13 is provided. Hydraulic cylinders 32, 34, 36 are shortened, and when the pressure of the bottom chamber (a) becomes the specified pressure, return oil switches the control valve 13 into an opened position (a) through a line 13d so as to communicate the line 2f with a line 2g. The return oil therefore flows from the line 2e to the line 2g and joins return oil at line 2h having passed through lines 2d, 2b so as to be exhausted to a tank 5. Pressure loss is thereby small, and the heating of operating oil is suppressed. When the hydraulic cylinders 32, 34, 36 are elongated, a directional control valve 3 is switched to a position (b), and the control valve 13 is switched to a closed position (b) by pilot oil pressure.  Even in the case of external force against an intention being applied to a working machine, since the return oil lines 2f, 2g are cut off, the hydraulic cylinders 32, 34, 36 are immobile.

Title: Susceptor
Inventor: NOZAWA TATSUO
IPC: C04B35/565
Filed: 1988-12-26
Abstract: PURPOSE:To prevent a wafer from coming into close contact with the spot-faced plane, and to surely take it out after an oxidation treatment and a CVD treatment have been finished by a method wherein a surface roughness of a spot- faced plane on which a semiconductor wafer is loaded is specified. CONSTITUTION:Regarding a surface roughness of a spot-faced plane, its average roughness (average roughness on the center line) is 1mum or lower, its maximum roughness is 10mum or higher and its flatness is + or -50mum or lower. In order to obtain the spot-faced plane of this surface accuracy, it is desirable to execute an oxidation treatment or a mechanical machining operation after an ordinary machining operation such as a surface grinding operation, a spot-facing operation, an NC milling operation or the like. That is, since the surface roughness of the spot-faced plane is adjusted properly, a wafer is not brought into close contact with the spot-faced plane. Thereby, when the wafer is taken out from a susceptor, it is not damaged and can be taken out satisfactorily.

Title: Absorption type water cooler heater
Inventor: OTSUKA SAKAE
IPC: F25B15/00
Filed: 1992-12-07
Abstract: PURPOSE:To eliminate a boiling-up noise of a solution generated in a regenerator when starting the operation of an absorption type water cooler heater. CONSTITUTION:There are provided a bypass pipe 24 which returns a part of solution in a solution feed pipe 4 to a dilute solution pipeline 23 and a solenoid valve 25 which opens and closes the bypass pipe 24. A high temperature regenerator 1 is provided with a liquid level sensor not illustrated herein. The liquid level sensor detects the liquid level of the solution and allows a solution circulation pump 19 to feed the solution into the high temperature regenerator 1 so as to keep a constant liquid level in the high temperature regenerator 1, which creates a filled-up state in the high temperature regenerator 1. When starting the operation, the control device opens the solenoid valve 25 and returns a lower temperature solution in the liquid lifting pipe 4 to the dilute solution pipeline 23. Therefore, lumps of bubbles collected on the base end of the liquid lifting pipe 4 are not condensed after their heat removal by the solution so that no sound is generated resultantly from solution-to-solution collision. When the temperature of the solution exceeds a predetermined temperature which ranges from 50 to 90 deg.C, the control device shuts the solenoid valve 25. Since then, the operation returns to normal mode.

Abstract: PURPOSE: To obtain a human BCDF useful fro treatment, etc., of immunodeficiency diseases by expressing a recombinant DNA comprising a gene coding for a polypeptide having human B cell differentiation factor activities and a vector nonreplicable in a eucaryotic cell therein. CONSTITUTION: A lymphocyte is separated from human peripheral blood according to a density-gradient centrifuging method, etc., using a Ficoll (R) pack, etc., and then transformed with a human T cell leukemia virus(HTLV) to provide a cell VT-1 capable of producing a human B cell differentiating factor(BCDF). The resultant VT-1 cell is subsequently cultured to separate an mRNA according to a conventional method. The separated mRNA is then used as a template to synthesize a cDNA, which is then used to prepare a cDNA library of about 150000 clones. The prepared library is subsequently screened with a probe to select a clone containing a gene coding for a polypeptide having human BCDF activities. The resultant gene is then integrated into a vector replicable in a eucaryotic cell to transform the eucaryotic cell and the gene is expressed to afford the human BCDF.
