Inventor: SAKAGUCHI MIKIO
IPC: C11D3/08
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To obtain a silicate-based builder having highperformance by mixing silica sand with water, an Nacontaining compound, a K-containing compound and a Cacontaining compound and/or an Mg-containing compound, subjecting the obtained mixture to hydrothermal treatment and baking the product. SOLUTION: Silica sand having a maximum particle diameter of <=5,000 μm and an SiO2 content of >=90 wt.% is mixed with an Nacontaining compound such as NaOH, a K-containing compound such as KOH and water and further a Ca containing compound such as CaCO3 and an Mg-containing compound such as MgO to obtain a mixture having a water content of 24-50 wt.%. The mixture is subjected to hydrothermal treatment under 5-15 kg/cm<2> G at 150-200 deg.C for 1-24hr, dried, baked at 300-1,500 deg.C for 0.1-24 hr and pulverized to obtain anhydrous inorganic builder. The objective crystalline product expressed by the formula xM2 O.ySiO2 .zMeO (y/x is 1.0-4.0; z/y is <=1.0; M is Na or K; K/Na is 0.01-2.0; Me is Ca or Mg) can be produced by suspending the above anhydrous inorganic builder in water and drying the produced hydrate.

IPC: B21D53/02
Filed: 1985-01-17
Abstract: PURPOSE:To subject a tentatively fixed member consisting of two sheets of plates coated with a flux over the entire surface and a corrugated sheet material fitted therebetween to aluminum brazing and surface coating without sagging and defects by preheating said member, dipping the member into an aluminum bath vessel etc. and cooling the member in a non-oxidative neutral fused salt kept at a low temp. CONSTITUTION:The element 7 fixed tentatively with two sheets of the plates 8 and the corrugated sheet material 9 by a spot welding or press machine is dipped into the flux 2 consisting of AlF3 and KF at 600 deg.C by which the element is coated with the flux over the entire surface and is preheated. The element is then dipped into the bath vessel 3 contg. pure aluminum 4 kept at 700 deg.C and is thereby brazed with the aluminum and is coated with the aluminum over the entire surface. The element is dipped into the non-oxidative neutral fused salt 6 consisting of KNO3 and NaNO3 at a low temp. of about 300 deg.C and is cooled in succession thereto. No sagging is generated owing to the specific gravity relation and the thermal impact and distortion are decreased. The satisfactory and uniform brazing and coating over the entire surface are thus made possible without exfoliation.

Title: Output buffer circuit
Inventor: OKUBO HIDE
IPC: H03K19/0175
Filed: 1989-01-13
Abstract: PURPOSE:To relax the abrupt variation of a current flowing through an output transistor(TR) without adding any extra circuit by composing part of a driving TR of FETs of equal size and connecting the gate electrodes of said FETs in series. CONSTITUTION:When a gate voltage is applied from an input terminal to an MOS TR1, the TR1 turns on a current flows from the output terminal of the TR1 to the ground. Delay is caused by a CR circuit between the gate electrode of the TR1 and the gate electrode of a TR2. Consequently, the TR2 turns on the delay time later and the TR3 and TR4 turn on, so that the current value increase. When the high-level signal from the input terminal become a low-level signal, TRs turn off from the TR1 at intervals of the delay time and the current value also decreases stepwise. When the input signal is at low level, the TR5-TR8 turn on stepwise and the current increases stepwise and is supplied from a power source terminal Vcc to an output terminal.

Title: Semiconductor device
Inventor: TANAKA YASUSHI
IPC: G03F7/26
Filed: 1990-01-17
Abstract: PURPOSE:To prevent the deformation of a photoresist pattern so as to improve the accuracy of the pattern by setting the level difference between the main surface of an element separating area and the main surface of an element forming area nearly equal to an integral multiple of the pitch of the standing wave. CONSTITUTION:An element separating area 2 and element forming areas 3 separated from each other by the area 2 are formed on a semiconductor substrate 1 and an MOS transistor 4 is formed in one of the areas 3 as an element. The level difference h2 between the main surface of the area 2 and main surfaces of the areas 3 is set at nearly equal to an integral multiple of the pitch (=lambda/20) of the standing wave. The lambda and (n) respectively represent the wavelength of the exposure light used for the photolithography for forming elements and refractive index of a photoresist material. Therefore, any place of a photoresist layer can be exposed to the same intensity of light, because the light reflected at the boundary between the thickest part of the photoresist layer and the base and the light reflected at the boundary between the thinnest part of the photoresist layer and base become the same in phase. Therefore, the pattern accuracy of a material layer can be improved.
