Title: Heat ray type semiconductor gas detection element for detecting air pollution
Inventor: FUKUI KIYOSHI
IPC: G01N27/12
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To lower humidity dependence and to detect low concn. gas by mainly constituting a metal oxide semiconductor to be coated of indium oxide containing a specific amt. of tin oxide. SOLUTION: A fine powder of indium oxide is impregnated with an aq. soln. containing tin chloride in predetermined concn. so that 0.5 atom.% of tin is contained to be dried and baked. The obtained indium oxide is further ground to form a fine powder which is, in turn, formed into paste by using 1,3-butane diol and this paste is applied to a platinum wire coil 1 with an effective dimension of 0.4 mm so as to cover the whole of the coil. The coated coil is further dried and a current is subsequently allowed to flow to the platinum wire coil 1 to bake the coil by Joule heat to apply and form a responsive layer 2 on the coil. At this time, if the content of tin oxide is about 0.1-50 atm.%, paste dispersibility is improved and the properties of tin oxide can be prevented from exceeding those of indium oxide.  By using indium oxide originally high in resistant and hard to receive the effect of humidity while controlling the valency thereof by tin, low concn. gas can be detected with high sensitivity.

Abstract: PURPOSE:To allow a decoding section to follow the counter speed even at high speed operation by connecting in multi-stage the flip-flops to outputs of a counter, and using the flip-flop output of each stage as a decoder of each stages so as to reduce the output wiring load capacitance of the counter. CONSTITUTION:A counter 10 is a 4-bit binary counter and each bit output and an output being the inversion of each output by inverters 11-14 are supplied respectively to a 1st stage flip-flop 30 and the output of the flip-flop 30 of the 1st stage enters a 2nd stage slip-flop 30 through the connection of the flip-flops. A decoder 20 is a 4-input AND gate constitution and the output of each stage of the flip-flop 30 is inputted to the decoder 20 of each stage. Since each bit output of the counter 10 is enough to be used as two inputs of the inverter and the first stage flip-flop, the fanout number goes to 2 and the output wiring capacitance of each bit is reduced. Thus, high speed decoding is attained.

Filed: 1986-12-19
Abstract: PURPOSE:To contrive simplification in controlling of pressing force of a mold by an injection cylinder, by a method wherein when the tip part of the injection cylinder comes into contact with a mold, torque of an electric motor is controlled based on pressing force set up beforehand. CONSTITUTION:Pressing force pressing a stationary mold 2 by a nozzle part of an injection cylinder 6 is set up through a pressing force setting instrument 13. When the injection cylinder 6 comes into contact with the stationary mold 2 by passing through a communicating passage provided on a stationary platen 1, a load to be applied to a servomotor 11 is increased. Consequently, an output electric current through a servoamplifier 12 is increased and the torque of the servomotor 11 is increased. Therefore, an electric current commanding value corresponding to preset nozzle touching force is applied to the servoamplifier 12 through a pressing pressure setting instrument 14. Therefore, at a point of time when the output current through the servoamplifier 12 has increased up to a value corresponding to the electric current commanding value, an increase of the current is suspended by the servoamplifier 12. Consequently, the servomotor 11 puts out the torque corresponding to the output electric current, through which the nozzle part of the cylinder 6 presses the stationary mold 2 by the preset nozzle touching force. Then molten resin is injected into a cavity through the cylinder 6.
