IPC: B01J31/02
Filed: 1991-01-22
Abstract: PURPOSE:To provide a method for producing a hydrogenation catalyst for hydrocarbon oil processing having an outstandingly higher catalytic activity than any catalyst which has hitherto been proposed and permitting reduction of the hydrocarbon operating cost. CONSTITUTION:As a base medium is used a catalyst supported on its carrier as an activated metal the group VI metal (Mo or W) and the group VIII metal (Co or Ni) in the periodic table or the catalyst containing phosphorus in addition thereto. To this catalyst are added at least one kind of glycolic acid, tartaric acid and the other specific carboxylic acids in an amt. of 0.3-3.5 times the total mols of the activated metals and mercaptoacetic acid, mercaptosuccinic acid or other specific org. sulfur compound in an amt. of at least 0.1 time the amt. required to change the activated metal into the sulfide form. The catalyst is thereafter dried at a temp. not higher than 200 deg.C to produce a hydrogenation catalyst. This permits an extremely easy production of the hydrogenation catalyst which can perform a high degree of the hydrogenation capable of desulfurization and denitrification of hydrocarbon oil under a milder operating condition than in the conventional operation.

Abstract: PURPOSE: To prevent undesired discharge phenimena and obtain copyed images free from stains by blowing air current in such a manner that the transfer paper having been transferred with toner images advances while making close contact to a conductive transfer roller in the plural sheet copying electrophotographic method.  
     CONSTITUTION: The electrostatic latent images formed on a photosensitive drum (electrostatic latent image holder)1 are developed to toner images in a toner developing machine 5. These are then transferred onto transfer paper 8' by a transfer roller 11 in a transfer part 6 and the process from the abovementioned developing is repeated to obtain the images of plural sheets. In the abovementioned transfer process, the transfer paper 8' having been transferred with the toner images is peeled from the photosensitive drum 1 by a peeling pawl 12 and is blown with air current 19 through hood 18 so that the transfer paper 8' gradually separates from the photosensitive drum 1 while making close contact to the transfer roller 11, whereby undesired discharging is prevented. It is desirable that the bias voltage for transfer be set slightly lower (about 450 to 700V).

Title: Semiconductor device
Inventor: SUMIDA WATARU
IPC: H01L27/04
Filed: 1994-02-21
Abstract: PURPOSE:To omit an independent protecting diode by setting the breakdown voltage of a separating layer, which separates a vertical-type output transistor from another region as a protecting diode for the vertical-type output transistor formed in one region of a junction separating type substrate at the intended value. CONSTITUTION:A source electrode S of a vertical type output transistor A2 and a separating layer 12 are connected. Thus, the transistor A2 is protected from breakdown by performing the breakdown between an otherconductivity type low-concentration epitaxial layer 5 and a one-conductivity type embedded layer 11 before the breakdown of the vertical type output transistor A2 when a high voltage is applied across a drain electrode D and a source electrode S. When the diode, wherein the junction is provided between the other- conductivity type low-concentration epitaxial layer 5 and the one-conductivity type embedded layer 11 is used as the protecting diode, it is not necessary to form a protecting diode at one region of the surface of the epitaxial layer 2. Thus, the area of a pellet can be made small.

Title: Tile reversing device
Inventor: ABE NORIO
IPC: B65G47/248
Filed: 1993-02-10
Abstract: PURPOSE:To reverse a tile positively while reducing impact applied to the tile to be reversed by providing a conveyor for conveying the tile and raising one cross-direction end side of the conveyed face gradually to reverse the tile. CONSTITUTION:When a tile is conveyed onto a horizontal conveyor 14 from a carry-in conveyor 12, one side edge part of this tile is placed on an ascending conveyor 16, and the other edge part is placed in the state of being caught by a protrusion 14b. When the tile 20 in this state is conveyed to the left in the drawing by the horizontal conveyor 14 and the ascending conveyor 16, the tile 20 is erected gradually so as to be finally put in the upright state. Since the downstream side in the conveying direction of the ascending conveyor 16 gets in more onto the cross-direction center side than the protrusion 14b, the tile 2 further keeps on rotating from the upright state so as to be finally turned over. The tile is thus reversed.

Title: Magnetic fluid seal
Inventor: MIZUMOTO MUNEO
IPC: F16J15/43
Filed: 1982-02-17
Abstract: PURPOSE:To pour a magnetic fluid into a seal gap neither too much nor too less and to fill up the gap with the fluid by disposing a magnetic fluid detecting element at an outflow portion for the magnetic fluid in a fixed member, and supplying the magnetic fluid in response to a detection of the detecting element for the existence of magnetic fluid. CONSTITUTION:When a magnetic fluid is poured into a seal gap by a pipe 6, the seal gap is gradually filled up with the magnetic fluid from the inside seal gap having a strong magnetic field first, until the magnetic fluid fills in the outside of a seal gap with an element 7. Since a general magnetic fluid has transmission factor of 2 to 3, when the magnetic fluid contacts the element 7, the magnetic flux density passing through the seal gap is increased to change the output voltage value of the element 7. By detecting a change in the output voltage value of the element 7 with a meter, the seal gap can be filled up with a required quantity of magnetic fluid.

A coffee waste compressed filtrate generated following the coffee manufacture is mixed with the coagulating sedimented sludge, and a mixture is dehydrated by a dehydrator 33, and the dehydrated filtrate is fed into a raw water adjustment tank 11.  The oil content in the coffee waste compressed filtrate is made to adhere to the coagulating sedimented sludge while being mixed with the coagulating sedimented sludge, dehydrated and drained together with dehydrated cakes. The oil content amount contained in the dehydrated filtrate, therefore, is reduced to control the adhesion of the oil content to granule methane bacteria.
