Abstract: PURPOSE:To prevent dark coloring of sealing glass by melting low-melting glass having >= a specific content of PbO in a golden crucible. CONSTITUTION:Glass raw materials such as silica sand, boric acid, red lead, Al(OH)3 and Sb2O3 are blended in a given weight ratio so as to have a low- melting glass composition having >=35% PbO content. Then, the glass raw material mixture is fed to a golden crucible, heated to a given temperature, melted, made to flow on a brass plate, etc., annealed to give transparent sealing glass free from dark coloring. By this production, the measured result of percent transmission of the glass plate in 200-700mum is shown by the curve (c) and that of glass plate by existing production is shown by the curve (d).

Title: Semiconductor memory device
Inventor: MIYAOKA SHUICHI
IPC: G11C11/34
Filed: 1985-03-20
Abstract: PURPOSE:To reduce power source dependency on an operating speed and a consumed power by providing an electric current source control circuit and controlling an operating current with respect to the change of a power source voltage in a reverse proportion. CONSTITUTION:A current source control circuit supplies the partial potential voltage of a power source voltage -Vee by partial potential resistances R5, R6 to the base of an NPN transistor T8. From a collector, a voltage reversely proportional to the change of the voltage -Vee is outputted and generates a control voltage VB through an emitter follower transistor T9. By this voltage VB, the operating current of the input circuit IB of an ECL side circuit having the ECL level signal of an external address signal is controlled so as to be reversely proportional to the change of the voltage -Vee. The ECL level signal becomes the selecting signal of a CMOS level by a level converting circuit LVC, an output circuit OB or the like. Accordingly, while a power source voltage is raised, the operating current is compensated, the operating speed of the CMOS side is enhanced and the reduction of the operating speed of the ECL side is compensated. As a result, as a whole of a RAM, the reduction of the power source dependency of the consumed electric power and the operating speed can be attained.

Abstract: PURPOSE:To prevent the jamming caused by a image holding body provided with lots of the image forming material on the leading edge part in the transporting direction or with the broken (torn) leading edge part, is not satisfactorily separated from the removing member. CONSTITUTION:When a transfer paper 10 provided with lots of the toner on the leading edge part in the transporting direction or with the broken (torn) leading edge part is transported from a paper feeding unit 20, an upper heating roller 45 is moved upward for releasing the state held in contact with a lower heating roller 46 (offset belt 44). As a result, the transfer paper 10 is not brought into contact with the offset belt 44 by the heating roller 45 but allowed to pass through a toner separating unit 40. Therefore, the transfer paper 10 is prevented from coming in close contact with the offset belt 44 through the toner heated and softened by the upper and lower heating roller 45 and 46, and from failing to be curvedly separated from the offset belt 44 satisfactorily around the separating roller 43.

Title: Draw rolling method of pipe
Inventor: YAMADA TAKEO
IPC: B21B37/48
Filed: 1984-03-22
Abstract: PURPOSE:To make the wall thickness of a pipe uniform by rolling a pipe stock having uneven wall thickness formed at the preceding stage by the stands within the first half ones of a draw-rolling mill while adjusting each interstand tension. CONSTITUTION:A pipe stock 1 formed at the preceding stage shows the uneven distribution of wall thickness, and is drawn by the rolls R1-Rn of a draw-rolling mill. An arithmetic and control unit 3 receives the signals outputted from a thickness meter 2 and computes the number of revolutions of rolls R1-Rn by a prescribed program to instruct the number of revolutions of motors M1-Mn. Now, when the meter 2 detects a wall thickness thinner than a target wall thickness, the unit 3 sets the number of correcting stands in accordance with the length of a thin wall-thickness part and accelerates the rolls R1 simultaneously when the front tip of this wall-thickness part is bitten by the 2nd rolls R21. In this way, the tension between the rolls R1, R2 is reduced, and the wall-thickness reduction is reduced. The necessary number of rolls R3 and succeeding rolls are accelerated in sequence to correct the wall-thickness reduction, and the wall thickness is therefore made uniform.

Title: Excrement treating agent
Inventor: YASUKAWA YOUICHI

Filed: 1983-03-31
Abstract: PURPOSE:To provide inexpensively an excrement treating agent capable of gelling and deodorizing the excrements at the same time by adding powdered zeolite to a water absorbing polymer. CONSTITUTION:The water absorbing polymer (sodium polyacrylate) absorbs water etc. by several hundred times its own weight in an instant, and is gelled. But the polymer has scarcely any deodorant function. Zeolite (zeolite rock) is a microporous material consisting essentially of aluminum silicate and having excellent absorbency and ion exchange property due to its molecular structure, and absorbs especially ammonia to a great extent. A mixture of 35wt% absorbing polymer and 65wt% powdered zeolite is preferred from the standpoint of the time for gelation, deodorizing effect, and cost. By discarding into a flush toilet after use, the treating agent is dissolved in water, passing through a sewer smoothly, and causing no trouble such as clogging.
