Title: Recovering method for valuable material from co-mo waste catalyst
Inventor: FUJIOKA HISAKIYO
IPC: C01F7/04
Filed: 1978-12-27
Abstract: PURPOSE: To recover valuable metals from waste catalyst by a method wherein Co-Mo waste catalyst together with alumina carrier is decomposed by alkali; Ni and Co are recovered by a high magnetic ore selector, and Mo, V waste liquid is reduced by treatment of alkali roasting.  
     CONSTITUTION: Waste catalyst used in heavy oil desulfurization process consists of alumina carrier, Co-Mo catalytic metal, Ni, V, S and tar deposition, etc. Alumina balls are sieved from waste catalyst, deposited tar and sulfer, etc. are burnt and removed by oxidation roasting, so that catalytic metals are formed into oxide. The oxide is then processed by alkali roasting to make Mo, V into water soluble alkali salts and Ni, Co into oxides. The treated material, after being crushed, is treated with water to extract alkali salts of Mo and V, which are reduced for recovery. The residue, i.e. mixture of alumina carrier, Ni and Co, is decomposed with alkali. The process produces water soluble alkali aluminate from alumina, which is extracted with water and separated, and the remaining Ni, Co, being paramagnetic body, is recovered by use of magnetic ore selector.

Title: Non-contact type heat fixing device
Inventor: OSADA MUNEAKI
IPC: B41J29/00
Filed: 1988-06-27
Abstract: PURPOSE:To shorten warming-up time by providing a control means which rotates a cylindrical fan at a high speed in warming-up. CONSTITUTION:In warming-up operation, the cylindrical fan 1 rotates at a high speed, and heat arising from a heater 4 is circulated in the device to accelerate movement in the device. When a temperature sensor 2 detects that temperature in the device reaches a prescribed temperature first time, the rotating speed of the cylindrical fan 1 is lowered to a prescribed speed, and hence onward a control circuit 3 controls the rotating speed at a constant speed. As a result, the interior of the device can be heated speedily and uniformly to shorten warming-up time.

Title: High pressure seal for gas compression piston
Inventor: TOMINAGA HIROSHI
IPC: F16J15/44
Filed: 1980-11-14
Abstract: PURPOSE: To prevent the leakage of gas and the hindrance of movement of a piston, by utilizing the action of rising gas pressure and the shape of the step of the piston and the shape of a pressure reception member to always automatically keep constant the clearance between a cylinder and the outside of a labyrinth ring.  
     CONSTITUTION: A piston 3 is provided with a step 5 so that the piston has a small-diameter tip part 4. An angle of θ is defined between the vertical facet 5a and conical facet 5b of the step 5. The difference between the outside diameter of a labyrinth ring 6 and the inside diameter of a cylinder 1 is equal to the clearance between them. The inside diameter of the labyrinth ring 6 is equal to the diameter of the small-diameter tip part 4. A plurality of such labrinth rings 6 are fitted on the piston 3. Spacers 7 of spring steel are alternately placed between the rings 6. The outisde diameter of each spacer 7 is much smaller than that of the labyrinth ring 6. The part of a pressure reception member 9 at the side of the rings 6 is shaped as a cone of the same vertical angle as the conical facet 5b of the step 5. The pressure reception member 9 is halted by a stop ring 10. When the pressure of gas under compression has reached the maximum level, the pressure reception member 9 is pushed rightward by the gas pressure depending on the pressure reception area difference between the front and back of the member to filt the labyrinth ring 6 leftward. For that reason, the minute clearance between the cylinder 1 and the rings 6 does not change despite the thermal expansion of the piston 3.

Title: Shipment of precious metal article
Inventor: MORIZUMI MASAHIRO
IPC: B65D81/02
Filed: 1988-06-29
Abstract: PURPOSE:To contrive the prevention of a precious metal article from bending, deformation and breakage by shipping the precious metal article immersed and sealed in a container filled with the fluid such as distilled and pure water. CONSTITUTION:A precious metal article is immersed in the fluid such as distilled and pure water filled in a container and sealed therein for shipment. The precious metal article is free from bending, deformation and breakage due to the absorption and alleviation by the fluid of the vibration and shock taking place in transit. Since the fluid is the distilled or pure water, there are not problems of the residual contaminations of the article and the after treatment for removal thereof is not required unlike the fluid such as a highly viscous oil. Also, there are no security problems such as volatilization, environmental pollution, ignition and combustion unlike the fluid having both degreasing and cleaning effects such as Freon and alcohol. For these reasons, this method offers an easy handling for shipment.

Title: Control device for proportional valve
Inventor: KITAMURA JUNICHI
IPC: F16K31/06
Filed: 1989-06-23
Abstract: PURPOSE:To perform high-precision control not affected by hysteresis with an inexpensive proportional valve by performing control in the moving state of the operation point to the invariably increasing direction on a curve when the increase side curve of the hysteresis curve is selected and in the moving state to the invariably decreasing direction when the decrease side curve is selected. CONSTITUTION:If an increase side curve is selected, when thermal power controllers 51a-51c of an operation section 5 are operated, the change request of the driving current is detected, and the operated controller and the set position are read. The set position is compared with the present position, and it is judged whether the request is the increase request of current or not. If the request is the increase request, the driving current is calculated, the current thus obtained is outputted to the corresponding proportional valve to drive the proportional valve to the desired degree of discrimination, and the gas flow is increased. If the request is the decrease request of current, the driving current is calculated, the current is outputted to decrease the valve opening once, then the current obtained by the preset equation is outputted to drive the proportional valve. When a decrease side curve is selected, similar actions are performed.

Abstract: PURPOSE:To attain thin profile of an equalizing characteristic display section and to decrease number of display elements by lighting two adjacent display elements so as to display an intermediate value of a characteristic compensation quantity instructed by a display element onto the two adjacent display elements. CONSTITUTION:For example, five display elements for characteristic compensation display each are used for each frequency, and when the maximum characteristic compensation quantity is <=+6dB and the minimum characteristic compensation quantity is >=-6dB, the level interval between dots is selected as 3dB to display the characteristic compensation quantity.
