Title: Fuel injection device for internal combustion engine
Inventor: MITSUYASU MASAKI
IPC: F02M51/00
Filed: 1988-07-07
Abstract: PURPOSE:To prevent any misinjection at time of starting from occurring with certainty by contracting a piezoelectric element at such a degree of velocity that a needle does not open a nozzle, immediately after an internal combustion engine stops. CONSTITUTION:In a drive control circuit 80, an ignition switch is turned off whereby a piezoelectric element 27 is discharged at a time constant tau. Here this time constant tau is determined so as to cause the piezoelectric element 27 to finish its discharge at time earlier than that pressure in a reservoir tank 35 is lowered and equilibrated, as well as not to cause a needle to open a nozzle 2 with contraction by discharge of the piezoelectric element 27. Capacity in a pressure chamber 18 increases and pressure goes down by the discharge of the piezoelectric element 27 like this, so that fuel is taken into this pressure chamber 18 by dint of pressure in the reservoir tank 35 via a clearance 17. When the piezoelectric element 27 has finished its discharge, fuel is filled up in the pressure chamber where capacity is maximized. Therefore valve opening force at the time of starting is thus secured.

Title: Water-dispersible coating composition
Inventor: ONISHI KIYOSHI
IPC: C09D163/00
Filed: 1987-07-07
Abstract: PURPOSE:To obtain a water-dispersible coating composition excellent in dispersion stability and adhesion to steel sheet and noncorrosiveness to steel sheet, by mixing an epoxy ester resin part of whose carboxyl groups are neutralized with a basic substance with colloidal silica. CONSTITUTION:A water-dispersible coating composition containing 100pts.wt. (in terms of resin solid) partially neutralized epoxy ester resin obtained by reacting an epoxy ester resin of an acid number of 20-80 with a basic substance in an amount necessary to neutralize 30-90% of this acid number and 5-150pts.wt. (in terms of silica solid) colloidal silica. When the acid number of the epoxy ester resin used is lower than 20, the hydrophilicity of the resin is low and the dispersion stability in water is poor. When this value is above 80, the hydrophilicity of a paint film, attained by a synergistic effect of the hydrophilicity of the colloidal silica, is too high, so that the noncorrosiveness is markedly lowered.

Title: Pigment dispersant for paint
Inventor: FUKUMOTO YASUHISA
IPC: C09D7/12
Filed: 1979-12-24
Abstract: PURPOSE: To improve dispersibility, low foamability and miscibility by using a water soluble copolymer of a cycloolefinic monomer and an unsaturated dicarboxylic acid anhydride as a pigment dispersant for coating.  
     CONSTITUTION: A cycloolefinic monomer such as Diels-Alder derivatives of cycloalkenes, cyclodienes, and cyclopentadiene and an unsaturated dicarboxylic acid anhydride are copolymerized in an org. solvent by using a polymerization initiator, and after the distillation of solvent, the copolymer is neutralized by a caustic alkali, whereby a water soluble copolymer is obtained. Although it is preferable to use this copolymer as an alkali metal salt such as Na or K salt or NH 4  salt, partly use of alkaline earth salt or unneutralized copolymer may be also possible. This copolymer  salt has low foamability, has high dispersion effect for various pigments and is further superior in blending with various resins.

Abstract: PURPOSE: To provide an automatic fabric washing machine for automatically deciding the amount and mixing degree of fabrics. CONSTITUTION: This fabric washing machine 10 is provided with a container 11 for the fabric and fluid for washing the fabric and a changeover type reluctance motor 14 is connected to the container. The motor is operated at constant torque and time required for accelerating the container and the load of the fabric from a certain speed to a speed higher than that is measured. The measurement can be repeated by using different torque input. From the measured value of the time, the scale of the fabric load is calculated corresponding to the inertia of a device. By using the scale of the load, the mixing degree of the fabric in the load is calculated. Water is added to the container in predetermined increments, the container is oscillated a predetermined number of strokes and the required torque is measured after each addition of water.  By using the required torque, since the torque is changed together with the scale of the load and the percentage of cotton in the load, the mixing degree of the fabric is calculated.

Title: Quartz oscillating circuit
Inventor: NOGAWA SHINICHI
IPC: H03B5/36
Filed: 1979-12-24
Abstract: PURPOSE:To perform stable class ''B'' operation, by providing a polysilicon resistance in parallel to a transistor equivalent to a feedback resistance. CONSTITUTION:Even in case of a drop in potential at point (b) due to a current flowing through leak resistance 9, a current flows from point (a) to point (b) via a polysilicon resistance serving as a feedback resistance. Even if the source-drain resistance of FET4 as the feedback resistance increases owing to back gate effect, the potential drop at point (b) can be supplemented. Further, providing coupling capacitor 7 between two FETs 1 and 2 constituting an inverter forms the loop of FET1 and FET3 for the feedback resistance, and consequently even if the power source voltage fluctuates, the potential at the gate bias point of FET1 follows up the fluctuations, so that stable oscillation can be carried out.

Title: Mold of continuous casting apparatus
Inventor: YAMAGUCHI MASARU
IPC: B22D11/04
Filed: 1979-12-24
Abstract: PURPOSE:To increase the hardness of a plating layer and prolong the life by containing Fe in the Ni plating layer of the copper plate of a mold. CONSTITUTION:The hardness of an Fe-Ni plating layer decreases roughly in proportional to the increase of the Ni layer. On the other hand, the rate of abrasion increases with an increase in the Ni amount. It is adequate to confine the Ni amount in the Fe-Ni plating to 20wt% for the lower limit, and to 45wt% for the upper limit. Next, Cr is added to Fe-20-45wt% Ni plating. Up to 20wt% Cr amount, no change occurs in globule adhesion strength, but in excess of 20wt%, the adhesion strength decreases significantly. Above 45wt%, the effect is so high that cracking in the plating layer occurs considerably. Hence, it is proper to keep the Cr amount at 25-45wt%. The life of the mold and the quality of a slab is improved as above mentioned.
