Title: Semiconductor switch
Inventor: KOHAMA KAZUMASA
IPC: H03K17/687
Filed: 1993-09-30
Abstract: PURPOSE:To provide a semiconductor switch with low the insertion loss and low distortions despite its small size and low voltage drive. CONSTITUTION:The pinch-off voltage VPB of a 1st field effect transistor TR stage 10B connected in series to a signal path is set at a potential lower than the pinch-off voltage VPA of a 2nd field effect TR stage 10A connected between the signal path and the ground potential. So that both stage 10A and 10B are not operated in the same operation characteristic. Thus it is possible to turn on only the stage 10B connected in series to the signal path without causing the leakage electric power at the stage 10A connected between the signal path and the ground potential. In such a constitution, the inserting loss and the distortions of a semiconductor switch can be further reduced.

Abstract: PURPOSE:To perform the logical copy of a file from a DKU to an MTU lowering a termination frequency in a tape travel by providing a table which describes the position or the size of a buffer where the data of plural blocks obtained from the DKU are stored. CONSTITUTION:A CPU1 transfers in order a file requested to copy from a DKU5 to an MMU10.

Title: Device for instantaneously excluding and displaying disconnected section of high voltage distribution line
Inventor: OKABE MISAO
IPC: H02H7/26
Filed: 1987-10-25
Abstract: PURPOSE:To confine service interruption only to disconnected sections and therefore to prevent electric shock accidents completely, by breaking the load side switch instantaneously by using a phase-failure relay, breaking the power source side switch by inverse power transmission through loop distribution, and transmitting power to the whole line except the disconnected sections. CONSTITUTION:The time periods for a breaking timer 8 and a connecting timer 9 are set to 8 seconds. In the case where a service interruption happens between switches N and (N+1), if the left side of the figure is the side of a power source, and if there is no inverse power transmission from the load side, the switch (N+1) is broken by its phase-failure relay 3. And then, if there is inverse power transmission, the switch (N+1) is made and the switch N is instantaneously broken by its phase-failure relay 3. Accordingly the switch (N+1) comes to have no phase-failure voltage, and as the contact of a relay 6 of the switch (N+1) changes from contact a to contact b because of the disappearance of the phase-failure voltage and the circuit becomes open, the switch (N+1) is broken in 10 seconds. This is also the case if the right side of the figure is the power source side.

Then, the storage circuit 4 and display circuit 6 when inputting the signals 5a and 5b have the storage contents and display contents rewritten into the signals 5a and 5b and the display circuit 6 counts the wave number rate of the input signal wave 2.

Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent the overvoltage of an output voltage, by simultaneously applying a continuous gate pulse to the thyristor of in-phase, high- and low- pressure side arms for 1/4 cycles or more on stop, and by allowing a DC current to circulate. SOLUTION: When an operation circuit 51 outputs a stop signal 51-1, a gate control circuit 44 outputs a signal of an arbitrary period, which is inputted to OR circuits 421 and 431, and a gate pulse is simultaneously fed to thyristors 11 and 12 of in-phase, high and low voltage side arms. At this time, when the stop signal 51-1 is generated for a period while a DC voltage is negative, the thyristor is not ignited, thus requiring the output of a gate control circuit 44 of 1/4 cycles or more. Then, when the DC voltage becomes positive, the thyristors 11 and 12 are ignited, the current circulates according to a loop of a DC reactor 4-the thyristor 11 and the thyristor 12-a DC current transformer 6-a thyristor current transformer, and an output current to a capacitor 21 is disconnected and attenuated, thus preventing the overvoltage of an output voltage on stop.

Title: Taste sensor and organic film therefor
Inventor: SANTO KAORU
IPC: G01N27/333
Filed: 1992-09-12
Abstract: PURPOSE:To obtain taste information, especially of sweet taste, in which measurement error is suppressed by arranging a molecule group of bitter taste substance while covering the entire surface of an electrode on the side coming into contact with a liquid to be measured so that sum of charges at the hydrophilic part directing toward the contacting part will be zero. CONSTITUTION:Molecule groups 61, 62 of a bitter taste substance are arranged on a base film 9 formed on a substrate 1 while directing the hydrophilic part outward over the entire surface of an electrode 2 on the side coming into contact with a liquid to be measured thus forming a single molecule film. In this regard, the molecule group 61 to be charged positive in an aqueous solution is mixed with the molecule group 62 to be charged negative at such ratio as the total charge will be zero thus substantially nullifying the reaction of an electrolyte, for detecting the acid and salty tastes, on the anion and cation. Since a taste sensor having conditioned surface charge is employed, taste information is increased and the sensor can be employed effectively even in case of sweet taste. For example, the weight of sweet taste term is increased in the simultaneous equations of taste in order to suppress measurement error of sweet taste.
