Abstract: PURPOSE:To smoothen variation in a drain current near a threshold value voltage by electrically connecting first and second source regions, first and second drain regions, and first and second gate electrodes, and varying the lengths of the first and second gate electrodes. CONSTITUTION:N pieces of N-type source regions 2-1,..., 2-n are formed on the surface of a P-type semiconductor substrate 1, and n pieces of N-type drain regions 3-1,..., 3-n are formed by separating at gate lengths l1,..., ln therefrom. N pieces of gate electrodes 4-1,..., 4-n are formed between corresponding source and drain regions on the substrate 1. Further, n pieces of N-channel transistors 5,..., 8 having different gate lengths l1,..., ln are connected in parallel. According to such a semiconductor, threshold value voltages in which drain currents of n pieces of N-channel transistors start to flow are different from each other. Thus, when the voltages to be applied to the electrodes 4-1,..., 4-n are varied, the drain currents are varied stepwise.

Title: Treatment of crude tar in coke preparation
Inventor: SUGIE YASUJI
IPC: C10K1/04
Filed: 1978-10-27
Abstract: PURPOSE: To obtain high quality tar, easily and economically, by the liquid-liquid- solid three-phase continuous centrifugal separation of crude tar produced from coke oven, into ammonia water, tar sludge and tar.  
     CONSTITUTION: Gas generated from a coke oven 1 is extracted by a blower 4, and a mixture of ammonia water and crude tar is separated into each component in a tar decanter by spontaneous precipitation. Tar sludge S 1  having larger diameter than the desired value is removed by this process. The residual tar sludge is continuously centrifuged by a separator 8 to remove the tar sludge containing little tar content. The ammonia water and the crude tar is introduced in a tar separation tank 11 in which the ammonia water is separated by the density difference. The crude tar is sent to a dehydrator 13 and subjected to the liquid-liquid-solid three- phase continuous centrifugal separation to separate water and tar ludge S 3 . The high quality, purified tar thus obtained is stored in a tar tank 14, and used as a fuel.

The method can effectively be applied, when a glass having a good refractive index is produced through the porous material. Namely, after a desired concentration distribution is given to the metal component, the porous material is immersed in the same solution as mentioned above, this immobilizing the metal component in the porous material. The concentration of the organic acid (salt) is preferably changed with time.

Abstract: PURPOSE:To attain to reduce the number of processes in thermal head substrate assembling work by eliminating the necessity for coinciding the average resistance values of resistors on substrates, in constituting a thermal head from two substrates, by independently controlling the duty of the pulse of th printing strobe signal of each substrate. CONSTITUTION:A monitor resistor 2 showing the average resistance value of a left side half substrate 4 and a monitor resistor 3 showing the average resistance value of a right side half substrate 5 are mounted to a thermal head 1.

Next, the duty of a printing strobe signal (the ratio of a time during printing and a total time) is independently determined to each of two half substrates by CPU6 and printing strobe signals are respectively sent to the driver IC10 of the left side half substrate 4 and the driver IC11 of the right side half substrate 5 from the left side control circuit 7 and the right side control circuit 8. Therefore, even when the average resistance values of the left and right substrates are different, same energy can be supplied to the resistors.

Title: Micro force evaluation system
Inventor: FUKATSU KEISUKE
IPC: G01L1/00
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To measure a micro force accurately by sustaining the displacement of a pendulum at zero when a micro force is measured and setting the flexure of a flexible coupling constantly at zero thereby increasing the sensitivity of the flexible coupling. SOLUTION: The flexible part 20a of a flexible coupling 20 forms a thin part at two column parts on the opposite sides of a rectangular hole 20e. When a force Fz acts along the central axis, i.e., the Z axis, of the detection part, a pendulum 30 turns about the rotational axis O-O passing through the flexible part 20a to cause a micro displacement at the forward end part thereof. Micro displacement at the forward end part of the pendulum 30 is detected from the variation in the quantity of light emitted from a light emitting element 40A and received by a light receiving element 40b. A signal designating the micro displacement is fed back to a torquer coil and the current flowing through the torquer coil is controlled to nullify the micro displacement. Since the restriction current is proportional to the force Fz, the force Fz can be measured.  Furthermore, since the displacement of the pendulum 30 can be kept at zero constantly, the flexible coupling 20 is not deformed plastically and the force Fz can be measured accurately.
