Title: Liquid cutoff valve
Inventor: NEMOTO HIDEO
IPC: B60K15/01
Filed: 1995-02-20
Abstract: PURPOSE: To make the valve of a disk remobale easily from a valve seat, by holding a valve disk tiltable at the upper side of a float by plural claws with different lengths, in a liquid cutoff valve to cut off the flowing out of a liquid by closing the valve, when a fuel tank or the like is inclined or overturned in the vehicle running condition. CONSTITUTION: When a liquid such as a fuel is reduced, a float 6 is going to sink by its empty weight, and a valve disk 32 stuck to a valve seat 18 is going to be lowered by removing it by plural claws 34 and 36. In this case, since the lengths of the claws are different, only the shorter claw 36 is hooked to the valve disk 32, and the lowering force is to be given. The valve 22 of the valve disk 32 is pulled by the short claw 36 and inclined when it is not separated rapidly from the valve seat 18 by cutting the contact with the valve seat, and the upper surface of the disk 32 is abutted to a projection 42. By making the abutting part as a fulcrum, the tensile force of the float 6 is operated as a moment. Consequently, the valve 22 is removed from the valve seat 18 easily so as to be opened.

Abstract: PURPOSE:To efficiently wash a biological filter apparatus with a reduced amount of washing water by together using air washing and water washing. CONSTITUTION:When a filter bed 2 is clogged by the continuation of biological filtration, the supply of raw water and that of diffusing air are stopped to perform water drainage from a washing waste water pipe 9. Subsequently, air is supplied at flow velocity of 0.3-0.8m<3>/m<2>/min from a washing air pipe 5 as an upward stream to perform the air washing of the filter bed 2 for 2-6min. Subsequently, simultaneously with the air washing at said flow velocity, washing water is supplied at flow velocity of 0.4-0.8m<3>/m<2>/min from a washing water pipe 6 to perform the water washing of the filter bed 2 by an upward stream for 0.5-2min. Thereafter, air is supplied at flow velocity of 0.3-0.8m<3>/ m<2>/min. from the washing air pipe 5 to perform air washing by an upward stream. After the filter bed 2 is allowed to stand for 1-3min, water is drained from the washing waste water pipe 9 and upper water is discharged from the filter bed 2 as washing waste water. As mentioned above, after the filter bed 2 is washed, raw water is supplied from a raw water pipe 3 and air is supplied from the diffusing air pipe 4 to reopen the biological filtering of the raw water passing through the filter bed 2 under the diffusion of air.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the mixture of foreign matters into a coin feeding part in order to prevent the failures of the machine and also to decrease the collection times of foreign matters. SOLUTION: The coins which are thrown into a machine body 1 are received at a coin feeding part and sent to a coin path. The coins to be dispensed are received at a coin receiving part 3. Then the coins can be taken out of the body 1 through a transaction port 13 formed above the part 3. A shutter 14 opens and closes the port 13 and has a throw-in port 15 where several pieces of coins put on each other can be collectively received. A shoot 17 directly carries the coins thrown into the port 15 to the coin feeding part. A shutter 16 opens and closes the port 15. Thus, it's possible to prevent the foreign matters from mixing into the coin feeding part by preparing the port 15 in addition to the port 13.

Title: Logic circuit
Inventor: KANO KAZUNARI
IPC: G01R31/28
Filed: 1985-03-22
Abstract: PURPOSE:To test the logic circuit having a terminal number N with using a test equipment having a smaller number of terminals than N by connecting the input terminal and the two-way terminal of the logic circuit to a test instrument, applying an output buffer to an output terminal in parallel, assembling the impressing signal of a control terminal and selecting one of output terminals. CONSTITUTION:When the impressing signal of control terminals CTL 1 and 2 of the test instrument is respectively made into an L level, an output terminal OUT 1 of a logical circuit 1 is connected to a comparator terminal T of the test instrument, and when the impressing signal is made into an H level, an output terminal OUT 4 of the circuit 1 is connected to the terminal T. Thus, in such a way, by controlling successively the impressing voltage of terminals CTL 1 and 2, the terminals OUT 1-4 are connected to the terminal T. Consequently, when a test pattern is impressed by synchronizing to the signal impressed to the terminals CTL 1 and 2, four output terminals can be successively measured. Thus, the logical circuit of the terminal number N can be tested by the test equipment of the smaller terminal number than N.

IPC: H04W52/02
Filed: 1993-03-17
Abstract: PURPOSE:To reduce the time for a waiting state where the power source of a reception circuit is turned ON by permitting the reception circuit to receive a preamble by inserting a synchronizing code word between a specified power conservation code and the preamble, and thereby making the reception circuit execute the reception operation of a data code. CONSTITUTION:When the top of the preamble 1 and a timing when power source is turned ON in a state where the reception circuit is intermittently receiving are coincident, the reception circuit receives the preamble 1 during 32 bits until its own power source is turned OFF so as to come into the state of waiting the reception of SC (synchronizing code work) 4 while the power source of the reception circuit is kept ON. After then, SC 6 is received so that the power source starts the reception operation of the data code 5 and is temporarily turned OFF. The power source is turned ON from behind by 160ms to several ms on this side by the falling of SC6. At this time the data code 5 is not transmitted from a transmitter so that reception operation is started by turning OFF the power source. Power consumption is reduced by inserting SC6 between the specified power consumption code 2 and the preamble 3.
