Title: Induction furnace with multilayer-lined structure where low permeability shaped material is arranged at outer layer of lining material
Inventor: ARIGA KIKUO
IPC: F27D1/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent such a trouble that low boiling point matter such as zinc or the like permeates into the texture within the lining refractory of an induction furnace, and that a molten metal leakage sensor operates, by putting an induction furnace in the two-layer constitution by an outer sleeve where the permeability is at a specified value or under and the vibrating charge work execution layer of dry monolithic material. SOLUTION: An outer sleeve 15 cm.cm/cm<2> .g/cm<3> .sec or under in permeability is installed on the body side of a furnace, and then a dry monolithic refractory is laid at the bottom, and then a former designed at the roughly center of the furnace is arranged, and it is cast in between the outer sleeve and the former, and it is charged with dry monolithic refractory under vibration while giving vibration by tapping it from inside the former. Hereby, the nonconformity by the permeation of zinc can be solved.  That is, even if a low boiling matter such as zinc or the like permeates into the texture of the lining material being made by charging it with a dry monolithic refractory under vibration, there is little permeation of zinc by the outer sleeve, where the permeability is mentioned above, constituting the outer layer of the lining material, so it does not end in the abnormal working of a molten metal leakage sensor.

Title: Preparation of platinum group metal-supported carrier
Inventor: YUUKI JIYUN
IPC: B01J23/40
Filed: 1981-03-06
Abstract: PURPOSE: To obtain the titled catalyst by a method wherein a refractory inorg. carrier is impregnated with an org. solvent containing a platinum group metal salt as a solute and the impregnated carrier is fired while an active metal is reduced in the surface layer part thereof.  
     CONSTITUTION: A refractory inorg. carrier such as alumina, or silica-alumina is impregnated with an org. solvent such as alcohols or ketones containing a paltinum group metal salt such as chloride or the like of platinum or palladium as a solute.

Title: Controller for industrial robot
Inventor: KATO HISAO
IPC: B25J9/18
Filed: 1987-02-16
Abstract: PURPOSE:To restrict the number of simultaneous driving units and to prevent a defective welding and the malfunction of a robot by calculating the voltage drop amt. by setting to the equipment generating a driving advance notice and setting the driving order and timing according to the priority. CONSTITUTION:A voltage drop amt. is calculated according to the equipment having received an advance notice already by receiving the driving advance notice generated before a fixed time in driving from each driving advance notice generating devices 6a-6c to decide by a deciding means 11 whether it is within the regulated value or not. In the case of its being within the regulated value, a driving permit is given by instructing the driving timing by a driving set means 12 and driving command placing means 13. In the case of beyond the regulated value the driving start time of the instrument with less working amt. and low priority is delayed by the driving set means 12 so as to become within the regulated value to obtain a driving permit at the following timing. The above is thus continued until the whole work is completed. Since the number of simultaneous driving units is restricted at the time when the voltage drop amt. is more than the regulated value the generation of the voltage drop beyond the limitation is prevented and defective welding is prevented.

Filed: 1992-01-22
Abstract: PURPOSE:To eliminate power consumption at the time of no use and to simplify a switching operation by guiding primary side leads of a transformer to a load side unit, and performing ON/OFF operations of an entire apparatus by a switch provided at the load side unit. CONSTITUTION:A rectifying adapter body 10 assembles a transformer 1 and a rectifier 2.

Filed: 1988-02-16
Abstract: PURPOSE:To reduce power consumption by constituting a circuit so as to change the level of an electromagnetic wave to be transmitted on a strip line consisting a superconducting material by a magnetic field generated by a current that flows on a control line. CONSTITUTION:A transmission path 4 which transmits the electromagnetic wave consists of the superconducting material of ceramics system, and functions as the strip line. First of all, the electromagnetic wave 7 is impressed on a transmission line 9a by a controller 10. The electromagnetic wave 7 is inputted to the transmission path 4 passing the transmission path 9a, and the transmission path 4 becomes a normally operated conductor by impressing the magnetic field on the transmission path 4 by a control line 6, and the transmission rate of the electromagnetic wave changes. The electromagnetic wave transmitting the transmission path 4 is inputted to a transmission path 9b, and is taken out as output by a controller 11. In the constitution, since the transmission rate of the electromagnetic wave can be changed remarkably by an electrical signal with a low voltage level, it is possible to match the electrical signal with the low voltage level with the electrical signal of an external circuit, and to reduce the power consumption sufficiently.

Title: Charge transfer type solid-state image sensor
Inventor: KOIKE NORIO
IPC: H04N5/335
Filed: 1987-02-18
Abstract: PURPOSE:To prevent the inflow of electric charge stored in the gate of a transistor into a detecting circuit, by constituting the channel of a reset transistor constituting a signal-charge detecting circuit with a plurality of regions being different in threshold voltage, and forming a potential barrier in the channel. CONSTITUTION:It is necessary to decrease noise charge, which flows into a sense capacitor in order to improve an SN ratio. As a means for this purpose, most of the charge stored beneath a gate electrode is discharged to a drain, and the noise charge, which flows into the sense capacitor, is suppressed as much as possible. In detail, a threshold voltage value of a source (the sense capacitor) beneath the gate electrode of a reset transistor DR is made higher than the drain 15. A potential barrier 14 is formed for the electric charge (electrons when the reset transistor has an N channel, and holes when the transistor has a P channel) in the vicinity of the source. Thus the inflow of the electric charge into the sense capacitor can be prevented.

Abstract: PURPOSE:To attain a high yield and to improve responsiveness as well as to eliminate the unequalness of a screen by equivalently increasing the (channel width)/(channel length) ratio of thin-film transistors (TFTRs) consisting of amorphous silicon films (a-Si) to provide a higher on current. CONSTITUTION:The width of the region in the transverse direction of the channels which attain electrical contact of drain electrodes 5 and source electrodes 6 of semiconductor film patterns is so disposed as to be on the inner side on gate electrodes 2 and the side walls of the semiconductor patterns existing on the lateral side of the channels are coated with the patterns of the drain electrodes 5 and the source electrodes 6. The side walls of the semiconductor patterns, therefore act as the drain electrodes 5 or the source electrodes 6 as well. Since the (channel width)/(channel length) ratio of the TFTRs is thereby equivalently increased, the on current of the TFTRs can be increased. The defective characteristics of the TFTRs which are provided in respective picture elements are decreased in the active matrix circuit board constituted of such TFTRs; in addition, the responsiveness is improved and the unequalness of the screen is eliminated.
