Inventor: TOYOSHIMA TOSHIYUKI
IPC: B32B15/08
Filed: 1991-08-02
Abstract: PURPOSE:To obtain a heat-curable resin compsn. good in solubility in a varnish solvent and low in varnish viscosity by blending a specific addition-reactive compd. with a specific polyamic acid having the terminals modified with silicon. CONSTITUTION:An addition-reactive compd. of formula I is mixed with a polyamic acid of formula II having the terminals modified with silicon to obtain a resin compsn. In the formulae, R<1> is a divalent org. group; R<2> is a 1-5 C org. group; R<3> and R<4> are each a divalent org. group; R<5> is a tetravalent org. group; and n >=2. The compd. of formula I, when blended, decreases the viscosity of a varnish thereof to improve the formability to enable formation of a thick film. Examples of the compd. of formula I include N,N'-(methylene-p-phenylene) bismaleimide and N,N'-tolylenebismaleintide. The polyamic acid of formula II makes the film tough and excellent in adhesion. The resin compsn. is usually prepd. by dissolving and mixing the compd. of formula I and the polyamic acid of formula II in an org. solvent.

Title: Fluorescent lamp and its manufacture
Inventor: MATSUO KAZUHIRO
IPC: H01J61/46
Filed: 1995-07-31
Abstract: PURPOSE: To suppress the adsorption of mercury to a phosphor to reduce its use, and enhance the safety of environments by providing a protecting film consisting of a metal compound transmitting the resonance line of mercury on the phosphor layer of the inner surface of a lamp vessel having mercury sealed therein. CONSTITUTION: In the manufacture of a fluorescent lamp, a phosphor is prepared, and applied onto the inner surface of a glass bulb 2 followed by drying to form a phosphor layer 3. Thereafter, a metal alkoxide is applied onto the layer 3, and dried at room temperature to hydrolyze the alkoxide. Further, the alcohol generated according to the advance of the polymerization reaction of the alkoxide is evaporated and removed, and the bulb is heated by a sintering furnace to generate a protecting film 4 of silicon dioxide or aluminum oxide. The bulb is then exhausted, and a rare gas and mercury are sealed therein to form the fluorescent lamp. Since the protecting film 4 transmits light of 254nm which is the resonance line of mercury at nearly 100%, it has no bad effect on the emission of the phosphor, and mercury is prevented from being adsorbed to the layer 3.

Title: Air-fuel ratio controlling device
Inventor: NICHIMA AKIO
IPC: F23N1/02
Filed: 1984-09-19
Abstract: PURPOSE:To make a substantial rational air-fuel ratio when a fuel consumption is high and in turn when the fuel consumption is decrease, an air-fuel ratio with excessive air or excessive fuel can be attained by a method wherein bias volume for adding or decreasing either a specified air flow rate or a flow rate of fuel is arranged. CONSTITUTION:A bias volume setting part 20 outputs a bias volume B. An amplifier 22 in an air system has a gain GA and an amplifier 23 in a fuel system has a gain GG. These outputs are connected to - input terminal and + input terminal of each of the differential amplifier 25. When the differential voltage D is zero, the air flow rate FA is increased (decreased) by an amount corresponding to the bias volume B. Under a high load, the flow rate of fuel is set to a high value FG1 an air-fuel ratio becomes a value M1 (M1') which is approximate to the rational air-fuel ratio M0, and then an efficient combustion can be carried out. When the ignition furnace 1 is heated, the flow rate of fuel is set to a lesser value FG2, the air-fuel ratio is M2 (M2'), resulting in an excessive air condition or air lacked condition and so the most appropriate combustion corresponding to the characteristic of the combustion furnace 1 is carried out.

Title: Electroplating device
Inventor: SHOJI SHIGEHIRO
IPC: C25D17/00
Filed: 1986-08-20
Abstract: PURPOSE:To prevent damaging of the plated surfaced of a flat square conductor due to the deposition of a plating metal on a feeder by providing an auxiliary cathode piece to be brought into contact with the feeder at the gap between the flat and square conductors to be plated when the flat square conductor is plated while being transferred in a plating soln. CONSTITUTION:The flat square conductor 21 to be plated is continuously transferred in the direction as shown by the arrow, and passed between anodes 7 and 7. In this case, the flat square conductor 21 is connected to the negative side of an electric power source 9 through the feeder 8a of a cathode rod 8 and allowed to function as a cathode, and the positively charged plating metal ion in the plating soln. is plated on the surface as a metal. Since the plating metal is also deposited on the feeder 8a and the plated surface of the flat square conductor 21 is damaged, the feeder 8a is brought into contact with the auxiliary cathode 11 connected to another power source 12 by the operation of an electromagnetic contactor 13 at the gap between the flat square conductor 21 separated from the feeder 8a and the succeeding flat square conductor, hence an electric current is passed in the direction opposite to that at the time of plating to prevent the deposition of the plating metal on the feeder 8a. As a result, the surface of the feeder 8a is always smoothed, and the damage of the plated surface of the flat square conductor 21 to be plated is prevented.

At the time of an action mode shorter than the time value in which the time interval of the successive frame recording action is stipulated beforehand, even after the frame recording is completed, the rotation condition of the rotation drum is made into the standard rotation condition as it is. In the frame recorder, by the switching operation from the external part of the frame recorder, the rotation condition of the rotation drum is switched to the low rotation condition and the standard rotation condition. The signal made into the object of the frame recording is stored at the time of a recording trigger signal and the stored signal is recorded as a signal for recording a frame.

Title: Semiconductor integrated circuit
Inventor: KITAZAWA AKITOSHI
IPC: H03K19/00
Filed: 1986-08-22
Abstract: PURPOSE:To prevent the malfunction of an internal circuit due to an undesired potential rise caused on a power line by detecting a change in an output of an output buffer from a high level to a low level thereby stopping the signal supply to the internal circuit by a level rise period of a ground line. CONSTITUTION:Output change detecting circuits SEN1-SENi detect a change in an output of output buffer circuits from a high level to a low level in the titled circuit having the output buffer circuits BUFo1-BUFoi having a ground line (not shown) in common and input buffer circuits BUFi1-FUBin. While any of the detection signals goes to a low level, an operation control signal phioutputted from an AND gate AND is brought into a low level during the period, and clocked inverter circuits CIV of all the input buffer circuits are brought into a high output impedance state during the period. As a result, even if an undesired potential rise is caused to the ground line because of the change in the output signal level in the output buffer circuits, the malfunction of the internal circuit is prevented by stopping the signal supply to the inside of the input buffer circuits.
