Title: Method for controlling size of injection-molded metallic part containing carbon
Inventor: KONDO TETSUYA
IPC: B22F3/02
Filed: 1992-06-17
Abstract: PURPOSE:To prevent a decrease in the dimensional precision of an injection- molded metallic product at the time of producing the product having a specified content of carbon by using a water-atomized powder and a gas-atomized powder lower in oxygen content than the water-atomized powder as the material. CONSTITUTION:When an injection-molded metallic part contg. 0.1 to several wt.% of carbon is produced, a mixture of >=1 kind of water-atomized powder and a gas-atomized powder lower in oxygen content than the water-atomized powder is used as the material for the part. Consequently, the O content in the raw powder of the product can be adjusted, and the fluctuations in the shrinkage factor of the molded article in sintering due to decarburization and deoxidation are suppressed since the reaction amt. of C with O is reduced. An inert gas such as gaseous nitrogen, argon and helium is appropriately used as the gas to be used to produce the gas-atomized powder.

Title: Plating method for protecting side face of pattern plated copper
Inventor: YOSHINO TSUNEO
IPC: C25D5/02
Filed: 1979-12-07
Abstract: PURPOSE: To prevent the side etching of a pattern plated copper in the pattern plating process, by forming two different resist images having different properties to solvent on the surface of copper.  
     CONSTITUTION: A resist image made of resin composed of an upper layer and a lower layer having different properties to solvent is formed on the surface of copper plated laminate sheet. The thickness of the upper layer is made larger than that of the lower layer i.e. the thickness of the lower layer is about 1/10 that of the upper layer. After the laminate sheet is pattern plated with copper, the upper layer is removed, and protective plated layer is formed on the pattern plated copper, than the lower layer of the resist is removed. The resist image is made by using such as the photosensitive resin a combination of thin film of photo-crosslinkable resin or photo-crosslinkable and polymerizable resin, with thick film of photosensitive resin having affinity of which to solvent is changed by exposure to light. For example, a photosensitive resin composed of a polymer having amino group and orthoquinone azide is used for the upper layer, and photosensitive resin contg. polyvinyl cinnamate for the lower layer.

Filed: 1979-12-07
Abstract: PURPOSE:To make it possible to spray easily in a simple structure by constituting such that a piston member is pushed into a cylinder by a push-up member to pressurize a liquid containing chamber. CONSTITUTION:When spraying is carried out, the push-up member 12 is preliminarily rotated to push the piston member 9 into the cylinder 2 and a pressurized condition is formed in the containing chamber 1. Thereafter, if a spray head 17 is pushed down to open an injecting valve 4, a liquid is supplied from the containing chamber 1 through a liquid conduit 3 and the injecting valve 4 and sprayed from the nozzle 6. If the spray head 7 is stopped from being pushed down, the injecting valve 4 is closed by a spring force and the spraying is stopped. Moreover, when the interior of the containing chamber becomes low pressure, if the push-up member is rotated again to pressurize the air in the contatining chamber, the spraying is enabled again. By this constitution, a pouring work of a high pressure gas is eliminated and there is no danger of explosion during incineration after disposal.

Abstract: PURPOSE:To eliminate the stress of the eye and to realize a large screen and lightweight display device by charging electrostatically and exposing a photoconductive plate, and changing an array of insulating particles layered on one surface of the photoconductive plate and forming and erasing an image. CONSTITUTION:Charges 6 are supplied to one surface 5a of the photoconductive plate 5 by an electrostatic charger 7 to charge the surface electrostatically and the particles are chained along lines of electric force, so the other surface 5b of the plate 5 is seen blackly. Insulating particles 4 come close where no lines of electric force are generated, so the surface is seen whitely. One surface 5a of the photoconductive plate 5 is irradiated with light for exposure by an optical system 9 after the electrostatic charging to erase the lines of electric force partially. Consequently, the white ground 11 of insulating particles 4 appears at the part 8a exposed by the optical system 9 and the black ground 10 appears from the other surface 5b of the plate 5 at the unexposed part 8b, thereby displaying an image. Thus, the brightness and hue are changed by a light nonemission material to make a display as if general printed matter were seen.

Abstract: PURPOSE: To enable time correction to be readily performed through inputting of the time correction signal at the necessary time and fixed time from the outside by forming a transparent electrode to the inside or back of the glass of the wristwatch and providing a time signal receiving circuit.  
     CONSTITUTION: When an AC field is applied to glass 1, the voltage (h) corresponding to the change in the electride field is generated in a transparent electrode 2. This voltage is inputted to a tuning circuit ± demodulating circuit 10 and a pulse detector 4.

This causes a time correction circuit 8 to correct the hour- minute-second counters of a watch circuit 9. Time correction is accomplished by the signal by the electric field through the operation of merely removing the watch and placing the same on a time corrector.
