Title: Production of catalyst for water-hydrogen exchange reaction
Inventor: NAKANE RIYOUHEI
IPC: B01J33/00
Filed: 1978-08-18
Abstract: PURPOSE: To obtain the catalyst which is not only provided with various conditions to be provided as the water-hydrogen exchange reaction catalyst but also has high activity and long life and is suited for volume production.  
     CONSTITUTION: The foam composed of hydrophobic material or the foam covered with hydrophobic material is impregnated with the gel type high molecular monomer solution mixed with monomer, crosslinking agent and, depending upon cases,  polymerization initiator by an orgainc solvent which dissolves the monomer but  does not dissolve the crosslinked polymer formed as a diluent and both are polymerized on the spot. On this is carried the metal catalyst of Group 8 of the periodic law  table. The most desirable gel type high polymer as the carrier of the catalyst of this  invention may be obtained when styrene is used as the monomer using the gel type  high polymer, divinyl benzene as the crosslinking agent and amyl alcohol as the  diluent.

Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To make the improvement of image quality and the restriction of image formation cost compatible by controlling the operation of preparing for image formation based on the quiescent-time interval of an image forming operation and an amount of moisture in an installation environment. SOLUTION: When a copy button is turned on or a print signal is inputted and in the case where, with a main power source kept on, an environment contains a specific amount of moisture or more and a time interval between the input of an image forming operation signal into a machine and the completion of the previous operation exceeds a specific time, the device judges that the machine is left for a long time with low power M (in a state of not being first in the morning), and starts the operation of preparing for image formation. A developing-unit drive motor is first operated to rotate the sleeve of a developing unit, the copy button is turned on in advance and, at the same time, a drum drive motor is operated to idly rotate a drum. A pre-exposure is lit on and a cleaner system is driven at the same time, and with the cleaner system also idly rotating, an area SS of the operation of preparing for the image formation is added and the drive of the developing unit consequently starts.

Abstract: PURPOSE:To prevent intrusion of the corrosive gas and thus to eliminate occurrence of the disconnection fault by convering over the exposed areas of the input and output electrodes produced with the Al evaporation film with the thin and dense Al2O3 layer which is heated in the oxidizing atmosphere containing H2O. CONSTITUTION:Al is evaporated on piezoelectric substrate 1 composed of LiTaO2, LiNbO3 and others and with the surface polished, and then input electrode 8 and output electrode 9 are formed through the photo etching process. A thermal treatment is then given for 30-100 minutes at 300 deg.C and in the oxidizing atmosphere containing H2O of 5-30wt%, and as a result thin and dense insulator protective film 10 of Al2O3 is grown over electrodes 8 and 9. In this case, the thickness of film 10 is set preferably to 2000-7000Angstrom  in order to avoid lowering of the excitation efficiency of the surface wave. In such way, the intrusion of the corrosive gas and the short fault caused by sticking of the foreign matters in the air can be eliminated, thus ensuring the steady property for a long period of time.

Abstract: PURPOSE:To expand the operating range of a power source without increasing the current consumption of a level hold circuit by providing a transistor which inputs a signal to be controlled for opening and closing the connection between a balanced bit line pair and the counter electrode plate of a memory cell. CONSTITUTION:In case of writing a high (H) level in a capacitor C1 for memory cell, a signal phi for pre-charging bit line first becomes H and transistors (Trs) Q7-Q16 are turned on and, accordingly, bit lines BL1-BLn and a cell plate CP become V0 in potential. Then the signal phi become a low (L) level and the Trs Q7-Q16 are turned off. When a word line WL 1 is opened and the (H) is written in the capacitor C1 in such state, the potential of the cell plate CP positioned as the counter plate of the capacitor C1 rises to potential V1. Then the word line WL 1 is closed and the Trs Q7-Q16 are turned by means of the signal phi. As a result, the bit lines BL1-BLn and the cell plate CP become the same potential V3. Similar operations are performed when a low level is written in a capacitor C1 for inverse memory cell.

Title: Two-stroke internal combustion engine
Inventor: ISHII MITSUNORI
IPC: F02B75/02
Filed: 1990-04-18
Abstract: PURPOSE:To improve engine performance in a wide operating region by lessening the operating angles of an air supply valve and an exhaust valve, and timing-advancing an operating center angle with the transfer of an engine speed from a high revolution region to a low revolution region. CONSTITUTION:Fuel is injected from a fuel injection valve 7 at the vicinity of the compression top dead center of a piston 3. An exhaust valve 6 is opened in the latter half of a combustion stroke to exhaust a burnt gas from a combustion chamber 4, and also an air supply valve 5 is opened at this side of the bottom dead center to pressedly feed fresh air. In this case, in a variable valve mechanism 10 opening and closing the air supply valve 5 and the exhaust valve 6, a valve operating angle is made small and an operating center angle is timing-advanced in an engine low revolution region, while an operating angle is made large and an operating center angle is timing-delayed in a high revolution region. Consequently the overlapped quantity of the air supply and exhaust valves is lessened in the low revolution region and is expanded in the high revolution region. As a result, the blow-by of the fresh air can be reduced so as to lessen the work loss of a supercharger in the low revolution region. Also air supply efficiency can be improved by utilizing inertia force in the high revolution region.
