Title: Mold
Inventor: MURAKAMI KEISUKE
IPC: B22D17/22
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of cracks in a molding body even if the molding body is subjected to a thermal cycle of being heated and cooled by allowing the coefficient of linear thermal expansion of a retaining member in a width direction of the molding body to match with that of the molding body. SOLUTION: A molding body 22 for a female mold A is filled in a space 23a between a master molding surface 21a of a master mold 21 and a molding layer 23. Secured to the back to the molding layer 23 are a joint-strengthening member 24, a strengthening member 25 and a concrete 27 that function as a retaining member. The concrete 27 is introduced into an iron formwork 29 and timbers 28, 32 are imbedded in a cement material. Since the molding body 22, molding layer 23, joint- strengthening member 23 and strengthening member 25 are all composed mainly of a thermosetting synthetic resin, the coefficients of linear thermal expansion thereof are substantially in the order of 30×10<-6> , and therefore even if the molding body 22 is contracted or expanded, there is generated no crack.  In addition, since the coefficient of linear thermal expansion in a longitudinal direction of the timber 28 is great, it is possible to allow the contraction and/or expansion of the entire concrete 27 to match with the contraction and/or expansion of the molding body 22.

Title: Pump for pressurizing and transporting granular body
Inventor: MIWA MITSUSUNA
IPC: B65G53/40
Filed: 1985-01-30
Abstract: PURPOSE:To press the seal surface of a seal disk uniformly with a proper pressure to prevent an operative medium such as powdered coal for leak from the seal surface by forming an annular flow path on the seal surface. CONSTITUTION:Powdered coal is filled in pockets P2, P1, Pn under the atmospheric pressure and gravity and moved clockwise to be blown away at a Pocket Pi by high pressure gas. Then, high pressure gas is filled in the vacant pocket and vertically sandwiched between the seal surfaces of seal disks 18A, 18B. When the gas proceeds under this condition to a position crossing annular flow paths 24A, 24B shown in a pocket Pi-1, the high pressure gas in the pocket Pi-1 is sent through said paths 24A, 24B to the pocket Pi+1 with the powdered coal under the atmospheric pressure to increase pressure in the pocket Pi+1. Thus, the internal pressure is evened to pressure intermediate the pressure of high pressure gas and the atmospheric pressure so that seal surface pressure is made uniform circumferentially.

Title: Pyroelectric type image element and pyroelectric type image sensor
Inventor: OBARA HIROSHI
IPC: H01L27/146
Filed: 1979-02-16
Abstract: PURPOSE: To enable the element formation with very thin arbitrary area, by providing a plurality of parallel electrodes so that a pair of pyroelectric macropolymer layer can bridge the conductive layer at the center and the matrix shape can be formed at the external surface.  
     CONSTITUTION: The conductive layer 6 is provided over the entire surface of the surfaces opposing between a pair of pyroelectric macropolymer layers 7 and 8 with evaporation. The layer 6 is thinly formed in film shape so that the layers 7 and 8 can be heated at infrared ray radiation. Next, the row detection electrode groups x 1 ∼x 4  are placed on one surface of the layer 7 with bonding and the column detection electrode groups y 1 ∼y 4  are placed in contact with one surface with bonding so that matrix shape cross point with it can be formed. Those electrode groups are  formed thinly in film shape so that radiated infrared rays can heat the layers 7 and 8 effectively,  and the electrode groups at the infrared ray reception surface side are taken as transparent electrodes. The layer 6 is used with grounding so that electrostatic coupling can not be made among  the electrode groups x 1 ∼x 4  and y 1 ∼y 4 . With this constitution, the layers 7 and 8 are heated with  infrared rays to produce pyroelectricity and charge to the electrode groups. In this case, electric  signal is obtained by using the relation between the layer 6 and the cross point of the electrode  groups.

The treated slag is discharged and made discardable. On the other hand, a sulfur source is added to the copper- component to form the matte and thereafter the molten matte is maintained under <=0.6mmHg for >=5min by reducing the pressure in the vacuum refining device to evaporate away the impurities. The refined matte obtd. in the above-mentioned manner is treated repeatedly in a copper converter for treating the matte produced from the smelting furnace, by which the copper-component and the valuable materials contained therein are recovered.

Title: Ignition timing controller during vehicle speed control
Inventor: MURAMATSU TAKAHIRO
IPC: F02D17/02
Filed: 1988-01-30
Abstract: PURPOSE:To avoid combustion of exhaust gas and to prevent occurrence of knocking by reducing the target amount of fuel and delaying the target ignition timing when fuel is fed to a part of cylinders and fuel supply to remaining cylinders is stopped during speed control. CONSTITUTION:A control section 74 judges whether a speed limiter is turned ON or OFF based on a vehicle speed detected through a vehicle speed sensor 96. During such vehicle speed control where the vehicle speed reaches to a set level to turn the speed limiter ON, fuel is fed to a part of cylinders in an internal-combustion engine 2 and fuel supply to remaining cylinders is stopped. Then the target injection amount quantity of fuel to be fed to the part of cylinders is reduced to correct the quantity of fuel to the level under control of vehicle speed having a rich air-fuel ratio which is thinner than a normal rich air-fuel ratio. Thereafter, the target ignition timing is delayed and corrected to farther delay angle side than the normal ignition timing. Consequently, total air-fuel ratio can be thinned without sacrifice of the protective function of the internal-combustion engine 2, and increase of combustion speed can be prevented.
