Inventor: NAKAGAKI HARUSHIGE
IPC: H03H11/24
Filed: 1977-12-07
Abstract: PURPOSE:To eatablish the stable potentiometer not subject to the defective gate protection diode, in an electronic potentiometer formed with C-MOSFET having gate protection diodes. CONSTITUTION:In the region of negative for the gate bias voltage VGS 16, transister Tr24 is cut off and the voltage of the output terminal 32 is zero, and in the positive region of VGS 16, the output Vo at the terminal 32 is outputted with almost equal voltage as VGS with the bias diode 26 and the characteristics is oa shown in solid lines. When the output terminal 32 of the bias circuit is connected to the second gate 4 of the P channel MOSFET 20, and the output terminal 33 is to the second gate 8 of the N channel MOSFET 21, even if VGS 16 is varied with broad change, the second gate voltage is the same as the first gate bias voltage or zero potential, resulting that no protection diodes 11 and 14 are conductive. Accordingly, stable attenuation performance can be obtained.

Title: Method and instrument for measuring total oxidant concentration
Inventor: KASAMA KANAME
IPC: G01N27/416
Filed: 1990-06-06
Abstract: PURPOSE:To allow easy and prompt on-site concn. measurement with high accuracy by reducing the contact reaction product of a gas contg. the oxidant permeated through an air permeable diaphragm and a halogen ion with wide-area electrolytic electrodes. CONSTITUTION:The oxidant component in the specimen gas 1 permeates the air permeable diaphragm 2 and dissolves into an electrolyte 6 in a detecting section. This oxidant component reacts with the halogen ion in the liquid 6. An oxidant reducatnt and a halogen molecule are thereby formed. Since a prescribed voltage is impressed between the electrolytic electrodes 3 and 5 having the surface area of >= 10 times the apparent area, the halogen molecules are reduced to the original halogen ion by the working electrode 3 of a cathode and the oxidation reaction of the halogen ions in the liquid 6 is effected on the counter electrode 5 side of the anode and a current flows between the electrodes 3 and 5. This current value is proportionally related with the concn. of the total oxidant contained in the gas 1. The current value is measured by an ammeter 7. The concn. of the total oxidant in the gas 1 is determined by conversion from the data obtd. by collating the oxidant concn. previously measured by the conventional method using the same gas and this measured current value.

IPC: G05D1/02
Filed: 1986-06-24
Abstract: PURPOSE:To avoid the collision between unmanned carriers by starting the next shift of an unmanned carrier only when no unmanned carrier is detected on an extracted unit driving route. CONSTITUTION:The unit driving routes P43-P45 of each shortest distance between a stop area Z3 and a destination area Z4 of an unmanned carrier 5a are extracted out of a control table. If other unmanned carriers exist within those routes P43.P45, the unit driving routes P42, P41, P40 and P46 having distances other than the shortest one are extracted out of the control list. When no other unmanned carriers exist within those routes P42-P46, the shift of the carrier 5a is started to the next destination area Z4 through said routes P42-P46.

SOLUTION: An optical signal is subject to wavelength multiplexing by an optical star coupler 31 of the center node 30 and given to an AWG 32. Optical signals with wavelength bands of λ5, λ13 demultiplexed to an output port #1 of the AWG 32 are given to an optical receiver 13-1.

IPC: H05K1/03
Filed: 1992-06-08
Abstract: PURPOSE: To reduce a delay time in electrical signal propagation in a computer, by laminating a plurality of conductive layers between resin layers including a hollow space dispersed therein. CONSTITUTION: Cloth impregnated with a glass balloon is dried to form a prepreg. The prepreg is laminated and covered with copper foil 4 on upper and lower sides and heated under pressure to form a laminated body.
