Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain a plant root growth promotor containing a specific purine nucleoside and useful for plants such as strawberry, melon, lily, Brassica Rapa and Chrysanthemum coronarium. SOLUTION: This plant root growth promotor contains inosine as an active ingredient, and is preferably applied to soil or hydroponic water in the case of hydroponics. The inosine is not necessarily a pure product, and may be an inosine fermentation solution itself, its concentrate, its concentrated and dry product, crude inosine separated from the inosine fermentation solution, etc. The inosine is not a phytohormone, and has a wide applicable range. The inosine does thereby not give a special damage to a plant, even when excessively applied to the plant. The inosine is immediately utilized by organisms in soil to serve to the improvement of the soil, but does not give a damage to the soil.

Title: High dielectric strength mosfet circuit
Inventor: YOSHIDA ISAO
IPC: H03F1/22
Filed: 1978-05-24
Abstract: PURPOSE:To reduce the ON-resistance of the high dielectric strength MOSFET circuit which is formed through the totem-pole connection method by applying the bias voltage to each gate of the 2nd to n-th MOSFET's to secure easily the ON state at all times. CONSTITUTION:The totem-pole connection is given between MOSFET1 and other MOSFET2, and the voltage between source terminal 5 of FET1 and drain terminal 6 of EFT6 is split via resistance 3 and 4. And the dielectric strength of the circuit comprising terminal 5 and 6 plus gate terminal 9 is observed in the form of the sum of the dielectric strength between FET1 and 2. However, the ON-resistance of this circuit becomes identical to or higher than the sum of the ON-resistance between FET1 and 2. In this connection, bias power source 10 (higher than threshold voltage of FET2) is inserted so that the forward bias is applied to the gate of FET2 (the higher the voltage the better). As a result, the ON-resistance of FET2 can be reduced and thus the ON-resistance of this circuit can be decreased, thus improving the voltage-current characteristics.

Title: Method and instrument for measuring intensity of eartquake motion
Inventor: NAKANO HIROYUKI
IPC: G01V1/16
Filed: 1990-03-14
Abstract: PURPOSE:To detect the current intensity of the earthquake motion at an actual site by transducing the motion of plural one-mass-point pendulums which sense the acceleration of the earthquake motion into electric signals, storing only maximum vales of the electric signals and finding speed response spectra Sv, and finding spectrum intensity SI from a specific expression. CONSTITUTION:When the earthquake motion arrives, a motion detecting device A measures the motion of the respective pendulums. At this time, the motion of the respective pendulums is transduced by a moving coil type seismoscope B into the electric signals which are proportional to the speeds of the pendulums. Then a storage device D is stored with only the maximum values of the respective pendulums, one after another, through an arithmetic processor C. At this point of time, the maximum values of the respective pendulums are equal to Sv values to the natural cycles that the pendulums have. Then an arithmetic processor E inputs and integrates the maximum values with the respective cycles to calculate the SI value. The SI values is displayed on a display device F and stored in a storage device G.

IPC: G07G1/12
Filed: 1993-03-22
Abstract: PURPOSE:To ensure a flexible operation of an account close key setting this close key to an optional key excluding the close key with operation of a prescribed key. CONSTITUTION:An account close key which registers the payment of a customer is set to a department key which is not used excluding the account close key in a due operating procedure, with switch of a mode changeover switch 5 and based on the setting of a key layout. The set close key is stored in a key layout setting memory 3d. In the register processing in an actual application mode, a central operational processor 1 retrieves the memory 3d based on the identification code of a pushed key to decide the presence or absence of an account close key. If an account close key is confirmed, the key-based denomination registration of a setting memory 3c is read out. Then the registration processing is carried out for payment based on the denomination. Therefore the account close key can be set to a key that is not used to comply with the request of a user that requires a small number of department keys and a large number of account close keys.

IPC: H05K1/18
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To stabilize the characteristics of a module by eliminating the dispersion of the mount position of a power chip transistor in a high frequency power amplifier module.
