Title: Diecast method
Inventor: GOTOU TAKESHI
IPC: B22D17/12
Filed: 1978-07-05
Abstract: PURPOSE: To produce diecast products of high quality with a small consumption of reactive gas, in a reactive gas atmosphere diecast method, by charging reactive gas after evacuating the cavity and plunger sleeve interior.  
     CONSTITUTION: After completely clamping a movable die 1 and a fixed die 2, a plunger tip 5 is advanced to the position to block a pour port 6 of a plunger sleeve 4. A vacuum pump is operated to discharge air from an evacuating passage 9, and the pressure in the cavity 3 and plunger sleeve 4 is reduced. Then, a reactive gas such as oxygen is supplied from a reactive gas feed port 9 or 12, and the cavity 3 and plunger sleeve 4 is turned into a reactive gas atmosphere with a small amount of reactive gas. Then, the plunger tip 5 is set back to open the pour port 6, and molten steel 13 is charged into the sleeve 4, then the molten steel 13 is cast into the cavity 3 by means of the plunger tip 5. Thus is manufactured high quality casting free from casting shrinkage void due to inclusion of residual air.

Title: Exposure apparatus
Inventor: KANAI NOBUO
IPC: B41J2/445
Filed: 1989-04-01
Abstract: PURPOSE:To obtain exposure without unevenness of quantity of light in a good assembly manner and to raise a degree of freedom of a design by a method wherein light from a light source is radiated on a light diffusing component, and said diffused light is made to be incident to an imaging device via a light shutter array. CONSTITUTION:Exposure to a photosensitive material 7 is performed by diffusing light from a light source 1 with a diffusion reflecting board 4, by transmitting selectively said diffused light with a light shutter array 5, and by imaging it on a photosensitive material 7 with a converging light transmitter array 6. When the diffused light is used thus, even through a certain amount of error exists among arranging positions of the light source 1, the diffusion reflecting board 4, and the light shutter array 5, exposure can be performed without generating unevenness of quantity of light likely to impair the exposure. Further, since a halogen lamp of larger total light luminous flux which is high in a degree of freedom as the light source 1 can be used, the quantity of light necessary for exposure can be enough secured even though the diffused light is used.

Title: Hard aluminum foil for electrolytic capacitor
Inventor: KURAHASHI MASAHARU
IPC: C22C21/00
Filed: 1990-03-30
Abstract: PURPOSE:To obtain excellent electrical characteristics when etching is performed by a direct current and pulse direct current by a method wherein the purity of aluminum is above a predetermined value and a predetermined amount of Cu and a predetermined range of In and/or Sn are contained. CONSTITUTION:The purity of aluminum is 99.96% or above and Cu of 10 to 60ppm and In and/or Sn in the range of 0.5ppm<=In+Sn/1.5<=15ppm are contained. Cu stabilizes a passive film during etching and acts effectively to form fine pits. However, it is preferable that Cu be limited to 10 to 60ppm in order to increase the self-solubility of aluminum. When Cu is not greater than 10ppm, a passive film is not stabilized and a normal etch pit cannot be obtained, because the etch pit is distorted. If it exceeds 60ppm, aluminum dissolves by itself violently, and the side walls of the formed etch pit are dissolved. In and Sn have an effect for promoting the generation and growth of etch pits during DC etching. It is more effective than Sn, and one and half times the amount of In is required for Sn.

Filed: 1981-06-01
Abstract: PURPOSE:To keep effective reaction area of catalyst pellets as wide as possible by removing water which condenses in a catalyst container and retards a recombining reaction of an acid and hydrogen gas in a catalytic gas recombining equipment which installs in a storage battery such as a lead acid battery or an alkaline storage battery and recombines the acid and the hydrogen gas to form water in order to return into an electrolyte the acid and the hydrogen gas generating during use of the storage battery. CONSTITUTION:Water formed by combining of the acid and hydrogen gas in a catalyst container 3 penetrates by capillaly action into fine pores of catalyst pellets 2 applying no water-repellent treatment which is filled in the catalyst  container 3. Thus, water which retards a recombining reaction of the acid and  the hydrogen gas is removed.

Filed: 1988-04-07
Abstract: PURPOSE:To secure a non-planar work easily and accurately by arranging such that each moving chip is subjected to equal pressure of fluid filled in a fluid path when the outer end section of the moving chip contact with the work. CONSTITUTION:Upon rotation in tightening direction through a feed screw 23, a moving chip 5 contacting with the projecting face 31 31a of a work io moves to the inside of an opening. A moving chip 5 facing with a set-off face 31b is moved to the outside through the pressure of fluid in a flow path and contacted with the set-off face 31b. In such a manner, the moving chip 5 is moved corresponding to the shape of projecting to recessed face 31 of the work 30 and contacted therewith 31. When the feed screw 23 is further rotated in the tightening direction through a vice 20, pressure of fluid in the fluid path of a jig 1 increases but since the fluid pressure is uniform at all points, pressure is applied uniformly onto each moving chip 5. Consequently, moving chips 5 having same size can press the work 30 with same pressing force.
