Title: Medium for hydroponic culture
Inventor: YOSHIDA RYOHEI
IPC: A01G31/00
Filed: 1988-02-09
Abstract: PURPOSE:To prevent excessive moistening of seed and to get a good seedling, by using a medium having a hydrophilic material layer and a hydrophobic material layer. CONSTITUTION:A seed is put into an incision 4 of a hydrophobic material layer 3 such as foamed polyethylene. The seed is placed on the top of the lower hydrophilic material layer 2 such as rock wool by this process. The lower part of the seed is supplied with a moderate amount of water from the hydrophilic material layer. Excessive moistening of the upper part of the seed can be prevented by the lack of water-absorptivity of the hydrophobic material layer 3. A stout seedling can be obtained since the sprout of the seed grows while expanding the wall of the incision part 4.

Title: Current applying voltage measuring circuit
Inventor: HATSUTORI TAKESHI
IPC: G01R31/00
Filed: 1978-03-15
Abstract: PURPOSE: To prevent oscillation and accurately detect voltages by inserting a resistance in series to the measuring object to make the synthesized resistance value with the measuring object to positive characteristics and obtaining voltage detecting terminals from both ends of the measuring object.  
     CONSTITUTION: A series resistance R 0  is held inserted between the measuring object 1 such as MISFET of ground connection, etc. and the measuring output terminal T to which the constant current (i) outputted by the inversion amplifier circuit constituted by operational amplifers OP 1  thru OP 3  and the synthesized resistance value with the measuring object 1 becomes always of positive characteristics. Hence, such oscillation wherein the current (i) increases resulting in decreased voltage of the measuring object 1 and the current (i) further increased to reach supply capacity thence conversely decreases does not occur. Hence, the voltage drop by the measuring object 1 wherein the both ends of the measuring object 1 are voltage detecting terminals is connected to the operational amplifier OP 0  which acts as a voltage follower and is accurately detected with the high impedance voltmeter V whose other end is ground connection.

Title: Emergency changeover system
Inventor: FUNAKOSHI JUNICHI
IPC: H04M3/22
Filed: 1993-02-18
Abstract: PURPOSE:To prevent interruption of talking from a trunk line to a telephone set at the time of restoration from a fault by throwing a contact from the position of an exchange into the position of the telephone set based on a non-switching signal from a controller and giving a changeover permission signal to an emergency switching control circuit after no telephone current flows at the time of the restoration. CONSTITUTION:When system-down or a fault takes place in the normal operation, an emergency switching signal is supplied to a relay RL, the excitation of the relay RE is released and common contacts of switches SW1, SW2 are thrown to the position of (b). Thus, a trunk line forms a loop with the telephone set to make talking with the telephone set 5 thereby keeping talking even on the occurrence of a fault. When a main power supply is stopped, since the relay RL is not excited, the common contacts of switches SW1, SW2 are thrown to the position of (b) and talking is made between the trunk line and the telephone set 5. When the system-down is released and even when an emergency switching signal is set, the talking is continued. When the talking is finished, the relay RL is excited by a control signal of the controller 6 and the common contacts of switches SW1, SW2 are thrown to the position of (b) and the normal operation is started.

Abstract: PURPOSE:To make small the circuit component, by reducing the power consumption through the current limit at the application of abnormal voltage. CONSTITUTION:When an abnormal voltage is fed to output terminals 13, 14, the base potential of charging control transistors TR25, 26 is limited with current control Zener diodes 31, 32 and the collector potential of TR25, 26 is increased. The base potential of protection TRs 33, 34 is increased accordingly, and TRs 25, 26 are compulsively OFF when the relation of voltage drops VE1, VE2, VB1, VB2 of bias resistors 23, 24, 29, 30 is VB1>VE1 and VB2>VE2. Thus, the impedance of the entire circuit is greater and the power consumption of the charging circuit is smaller. Further, when the abnormal voltage is released, the relation is again VB1<VE1, VB2<VE2, and the operation restores to normal operation.

Title: Vibration controller
Inventor: SUMI AKIRA
IPC: H02P29/00
Filed: 1994-02-01
Abstract: PURPOSE: To apply both rotation and vibration to a load with a motor and to deal with a rapid acceleration/deceleration or an impact drop of speed. CONSTITUTION: When a frequency F* and an amplitude ΔN* of the vibration are applied, an amplifier 17 outputs a command torque 6 ' corresponding to the amplitude ΔN* and this is transformed into an AC signal by an inverse Fourier transformer 20 and outputted as a torque TAAC*. Then, since the torque TAC* is superimposed on a torque TDC* at an adder 8, a motor 1 gets the ripple (namely vibration) of the speed ΔN* while being rotated at the average speed NDC* under the control of a speed control loop 10. In this case, since the component of the frequency F* is sufficiently attenuated by a notch filter 40, the speed control loop 10 does not follow up the vibration component but performs only the speed control based on the commanded average speed NCD*.

Title: Method of controlling water temperature
Inventor: TANZAWA TAKANAO
IPC: F23N1/08
Filed: 1983-02-23
Abstract: PURPOSE:To provide a method of controlling the water temperature capable of measuring the flow quantity of water as well as the temperature thereof by use only of a temperature sensor. CONSTITUTION:Water flows within a water feed pipe 1 via a flowing water switch 2 and reaches a heat exchanger 3 wherein water is subjected to a heat exchange. Thereafter, hot water is supplied through a water plug 4. Reference numeral 12 designates a temprrature detecting thermistor which is provided in the vicinity of the heat exchanger 3. The thermistor 12 detects the temperature of supply hot water and supplies a detected value to a microcomputer (MPU) 13. The MPU carries out an operational processing by a water temperature signal to PID control a proportional control valve 10. When the increment of the reference value is set at 10%, for example, with respect to the step temperature output in a time TS produced from the MPU, differences in time t1 and t2 required for reaching this reference value are introduced depending on the flow quantity. In the case of the time t2(curve b), the flow speed is slow (small flow quantity). In the case of the time t1, the flow speed is large (large flow quantity). Accordingly, when the inner diameter of the water pipe is set at a predetermined value, the flow quantity can be obtained indirectly by measuring the above described times.

When signal 19 turns to 1, signal 18 turns to 0 for time T 2 . Time T 2  is identical to the action cycle of processor 3 to feature T 1 >T 2 . And now, processor 2 changes to the operation enable state from the operation unable state, circuit 13 receives signal 25 to turn signal 18 to 0 for time T 1 . After time T 1 , both processor 2 and 1 turns to the request enable state since the process cycle ends for processor 3.
