Title: Production of titanium oxide thin film
Inventor: KOGA SHOTARO
IPC: C02F1/72
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain a titanium oxide thin film improved in photocatalytic performance through being imparted with crystal orientation by hydrolyzing a tetra- lower alkoxytitanium's ethylene glycol monomethyl ether solution followed by adding polyvinylpyrrolidone to the resultant sol and then coating the surface of a heat-resistant substrate with the sol which is then baked. SOLUTION: This titanium oxide thin film having crystal orientation and high photocatalytic performance as well is obtained by the following procedure: an ethylene glycol monomethyl ether solution of a tetra-lower alkoxytitanium such as tetramethoxytitanium is hydrolyzed; wherein it is preferable that the concentration of the tetra-lower alkoxytitanium in the solution is about 0.01-2 mol, the hydrolysis catalyst is an inorganic or organic acid, and the reaction temperature is room temperature to about 80 deg.C; the resultant clear, stable titanium-contg. hydrolyzed sol is incorporated with about 1-30 wt.% of polyvinylpyrrolidone with an average molecular weight of pref. about 10,000-630,000;  the resultant titanium oxide film-forming hydrolyzed sol is then made to adhere to the surface of a heat-resistant substrate by dipping means or the like to form a gel film, which, in turn, is heated to about 300-700 deg.C and baked.

Title: Cache memory eliminating data discordance
Inventor: SAWADA MITSUO
IPC: G06F12/08
Filed: 1987-09-09
Abstract: PURPOSE:To eliminate the discordance of data between a cache memory and a main memory device caused by an access given to the main memory device from another master, by providing an address memory means which stores an address and the decision data to decide said address is valid or invalid. CONSTITUTION:The 1st and 2nd address memory means 7 and 8 store the address given from a CPU bus 13 and the address given from a system bus 4 connected with a main memory device and another master (DMA, etc.) as well as the decision data showing whether these addresses are valid or not. When said DMA changes the data on the main memory corresponding to the address stored in the means 8, the decision data on said address is set invalid. Then the use of this data is avoided when an access is received from a CPU. Thus the CPU uses the data on the main memory device and then replaces the data on a cache memory with the data on the main memory device to secure the coincidence between both data in case another master changes the data on the main memory device to cause the discordance with the data on the cache memory.

Title: In-band signal transmission system
Inventor: OKAMOTO YOSHIHISA
IPC: H04L27/156
Filed: 1988-09-09
Abstract: PURPOSE:To detect a fault of a transmission line immediately by providing the 1st and 2nd oscillators with different oscillating frequency in the same frequency band as that of an analog signal to the sender side, interrupting an output of each oscillator in a complementary way so as to send a binary signal. CONSTITUTION:Each oscillation output from oscillators 1, 2 is interrupted in a complementary way to send each state of 'H', 'L' of a binary signal (a). A signal by complementary interruption in frequencies f1, f2 is extracted by filters 7, 8 in the reception section for each frequency and each output is brought into the state of 'H', 'L' at detectors 9, 10 and a logic circuit 11 decodes the state into a binary signal and the result is sent as a binary signal output R. Then the circuit 11 monitors whether or not each output of the detectors 9, 10 is complementary interruption and when either of the frequencies f1, f2 exists, it is regarded as a normal line and if neither of them exists, it is discriminated as a line fault. Thus, the line fault is immediately detected.

IPC: E03F1/00
Filed: 1994-09-20
Abstract: PURPOSE: To reduce the costs of manufacture and installation by periodically connecting the pressure side of a dry rotary vane pump to a collecting container in order to empty the content of the container to another space by means of the pressure generated by the dry rotary vane pump. CONSTITUTION: The suction side 5a of a pump 5 is connected to the atmosphere via a remote-controlled three-way valve 21 at the position of the arrow 21a to empty sewage in a collecting container 4. The pressure side 5b of the pump 5 is connected to the collecting container 4 via another remote-controlled three- way valve 22 and a tube 6a. The pressure generated by the pump acts on the sewage 17 since it cannot decompose the sewage 17 through a check valve 10 located near the downstream end of the end tube 3 of a sewer system. The pressure pushes the sewage into the container 4 and pushes it out into another space via the tube and a check valve 29.

Filed: 1986-09-25
Abstract: PURPOSE:To enable the title method to shorten time necessary for controlling a position of a blow nozzle accurately by measuring the central position of a mouthpiece part of a blow mold and that of the blow nozzle. CONSTITUTION:A mouthpiece is formed by fitting a die plate 12 to the center of the upper part of a blow mold 10 and a position detector 14 is provided on the top of the mold 10. When a ball 22 is put on the die plate 12, the ball 22 comes into contact with a circular cone of the same and the central position of the ball 22 is turned into a state where it is coincident with the central position of the die plate 12. Measurement of a position of the ball 22 is performed by the position detector 14 under this state. In other words, the measurement of the position in an X-wise direction is performed by a light emission part 16a and light receiving part 18a and that in a Y-wise direction is performed by a light emission part 16b and light receiving part 18b. Then the positions in the X-wise and Y-wise directions of a blow nozzle 20 are measured by the position detector 14 under a state where the ball 22 is removed and the blow nozzle 20 is descended down to a blow position. Then a difference between both measured results is calculated and control of the position of the blow nozzle 20 in a horizontal direction is performed so that the central position of the blow nozzle 20 coincides with that of the ball 22.
