Patent JP-H02210935-A (JP)
Title: Signal transmission system
Inventor: WATANABE YUICHI
IPC: G06F13/00
Filed: 1988-08-31
Abstract: PURPOSE:To select one started terminal equipment with the highest priority among plural started terminal equipments with once polling only from a central processing unit by allowing a started terminal equipment detecting the start of other terminal equipments to stop the transmission of a succeeding its own address signal. CONSTITUTION:A current mode signal from a terminal equipment 5 during terminal transmission period RTM is converted into a voltage mode signal by a central processing unit 1 and the converted signal is sent to a transmission line 3. Thus, all terminal equipments and a monitor display panel 7 use the voltage mode signal to discriminate the content of terminal equipments connecting to the post-stage with respect to its own equipment and also of a current mode signal from terminal equipments connecting to the pre-stage. Thus, the display panel 7 is able to be connected to an optional location of the transmission line 3. Furthermore, since any terminal equipment discriminates the signal transmission state of all terminal equipments by the voltage mode signal, the terminal equipment itself discriminates the idle state of the transmission line 3 and the presence of signal collision.

Title: Fuel injection amount control device for internal combustion engine
Inventor: HAMAI KYUGO
IPC: F02M51/06
Filed: 1986-09-18
Abstract: PURPOSE:To provide a fuel injection control device which can cope with idle rotation at a further lower rotation speed and high speed rotation, by a method wherein the piezo-electric element of a lamination piezoelectric body is divided into plural groups, and the number of groups, applying a voltage according to the running state of an engine, is varied for control. CONSTITUTION:A control circuit 30, receiving an injection pulse Ti from a microcom puter, simultaneously receives a running state detecting signal S. When a demand fuel injection amount is low, the signal forces a switching circuit 42 to be turned OFF, inhibits a part-B drive circuit 34B against driving, and inputs an amplification output from an injection pulse Ti to a part-A drive circuit 34A to drive it to displace only the part A of a lamination piezoelectric body 20. Thus, a lift amount of a valve body 11 is decreased. When a demand fuel injection amount is high, the switching circuit 42 is brought into an ON-state by means of the signal S, the part-A, driven circuit 34A and the part-B drive circuit 34B are simultaneously driven, both the parts A and B of the lamination piezoelectric body 20 are displaced, and a lift amount of the valve body 11 is increased. Therefore, since in addition to control of an injection pulse width Ti, a lift amount of the valve body 11 is controlled, a running region is also increased in a range.

IPC: H04W36/36
Filed: 1991-08-05
Abstract: PURPOSE:To enable accurate channel switching on the boundary of the minimum cell by distinguishing between the use of two channel switching decision references corresponding to the magnitude of the change of the reception level in the mobile device. CONSTITUTION:The reception level of the mobile device is inputted to long- interval average units LTA0 to LTAN and short-interval average units STA0 to STAN. To the units LTA0-STA0, the reception level of communication cell is inputted. To the units LTA1 to LTAN and STA1 to STAN, the reception level of the adjacent cell is inputted. The output of the unit LTA0 is inputted to an addition unit SN, to which a small hysteresis margin is added. The output of the unit STA0 is inputted to an addition unit SW, to which a large hysteresis margin is added. Thus, the output of comparators C1 and C2 are inputted to a gate OR1 by distinguishing between the use of the two channel decision references corresponding to the intensity of the change of the reception level, and the channel switching is started by the output of the gate OR1.

Title: Sampling clock generating circuit for video signal
Inventor: MATSUSHIMA KENICHI
IPC: H04N5/91
Filed: 1985-10-01
Abstract: PURPOSE:To correctly sample a video signal by using a PLL circuit incorporating a voltage control oscillator, using the number of clocks or an integer times value of the video signal of 1H such as an H signal for a reference input and providing a frequency dividing circuit in an output of the oscillator. CONSTITUTION:A frequency dividing circuit 5 divides a sampling clock 10 and converts into a fraquency dividing signal 7 of the same frequency as an H signal. This circuit 5 uses a programmable counter so as to change a frequency dividing ratio and sets the number of clocks of a video signal of 1H period as the frequency dividing ratio. In order to divide an output signal of a voltage control oscillator VCO, the sampling clock of a frequency lower than a range of an oscillating frequency of the VCO can be generated. Thereby, the range of the frequency of the video signal can be considerably widened.

Title: Treatment of wastewater of oil station
Inventor: HIRANO HIROSHI
IPC: C02F1/40
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To efficiently remove the contaminants of the wastewater discharged from an oil station by processing the water part separated from oil with an adsorbent. SOLUTION: When the wastewater discharged from the oil station or the like and containing gasoline or the like is treated, the wastewater is first introduced into a treatment tank 1 of the uppermost stream. Activated carbon is put in the tank 1 and an air injecting pipe 10a is inserted at the bottom. When air is injected into the wastewater in the tank 1 through the pipe 10a, the wastewater is agitated and the activated carbon becomes a fluidized state. As a result, the contaminants in the wastewater are efficiently brought into contact with the activated carbon and adsorbed on it, and the wastewater is furthermore purified by aeration treatment. The wastewater thus treated with the activated carbon in the tank 1 is introduced into a treatment tank 2 for purification with fluidized activated carbon while being agitated by the air injected through an air injecting pipe 10b.  The wastewater discharged from the tank 2 is subjected to a similar treatment in a treatment tank 3 as in the tank 2. The purified wastewater is then discharged to the outside.
