Filed: 1986-08-01
Abstract: PURPOSE:To separate a lighter fluid having a lower concentration and a heavier fluid having a higher concentration from each other through utilizing a difference in the property of adhering to and flowing along a wall surface, by leading a fluid to a slant surface on the back side of a slant part. CONSTITUTION:A slurry fed into an intermediate tank 1 drops through a supplying pipe 2 under a fixed dropping pressure.

The slurry drops into a first collecting member 4, is collected, and is fed to a tank 6 through a taking-out pipe 4a. On the other hand, a heavier slurry having a higher concentration drops from the supplying pipe 2 entirely, or a portion thereof starts flowing along the slant surface 3b but drops off the intermediate part of the slant surface 3b under its own weight. The heavier slurry drops into a second collecting member 5, and is fed to a tank 7 through a taking-up pipe 5a. Where the angle of the slant surface is 40-65 deg., a slurry containing at least 32% of a clay with a specific gravity of 2.6 drops as the heavier slurry into the second collecting member 5.

Title: Optical signal recording disk
Inventor: DEGUCHI MASAHIRO
IPC: G11B7/2405
Filed: 1986-08-01
Abstract: PURPOSE:To contrive to attain the simplified and low-cost device by providing a recording film capable of recording/reproduction a signal at a recording and reproducing device, recording the signal in a rugged pit form in advance, and applying the device with initializing processing to make the rugged pit signal recording part to a constant state. CONSTITUTION:A beam 11 corresponding to a recording light is radiated onto a recording disk 1 by a device similar to a recording and reproducing device to give a change in advance to the crystal state. Thus, in using the disk 1 for the reproduction purpose in the recording and reproducing device, if the reproduced light goes to recorded light due to a fault or the like of the device, since the crystal state corresponds originally to the recording state, no large change is caused and no recording software is destroyed (initial processing). The reflectance of the recording disk 1 and the recordable disk is not largely difference and the gain and adjustment level changeover for the servo system and the signal processing system is required. Thus, the recording and reproducing device is simplified and made low in cost.

Title: Glass paste for airtight sealing
Inventor: KABEI TOSHIHIRO
IPC: C03C8/10
Filed: 1988-07-20
Abstract: PURPOSE:To provide a glass paste capable of high-quality airtight sealing by mixing a low-melting PbO-B2O3-Tl2O-based glass powder with a calcining assistant consisting of polyethylene glycol and an organic solvent for regulating viscosity. CONSTITUTION:A low-melting glass powder, containing 50-60wt.% PbO, 5-10wt.% B2O3 and 10-30wt.% Tl2O and having a softening point within the range of 250-450 deg.C is prepared. The low-melting glass powder is mixed with a calcining assistant consisting of polyethylene glycol and an organic solvent (e.g. alpha- terpineol) for regulating viscosity to provide a glass paste for airtight sealing. The above-mentioned glass paste for airtight sealing is preferably used especially for airtight sealing display tubes, such as fluorescent tubes or plasma display tubes, without a vent tube. Since the polyethylene glycol which is the calcining assistant can be completely removed within a proper calcining temperature range of the glass powder, high-quality vacuum airtight sealing without fouling can be realized.

Patent JP-S6425555-A (JP)
Title: Trench forming method
Inventor: MURAKAMI ISAO
IPC: H01L21/822
Filed: 1987-07-22
Abstract: PURPOSE:To shorten an interval between neighboring trenches and to suppress the occurrence of soft errors, by forming the embedded wall of an insulating film in the vicinity of the side wall of the trench, and forming a capacitor insulating film and a capacitor electrode in the trench. CONSTITUTION:A silicon nitride film is deposited on the entire surface of a silicon substrate 1 by a chemical vapor growth method. Then, a silicon nitride film 3 is made to remain only on the side wall of the trench 2 by anisotropic etching. Thereafter, an amorphous silicon layer 4 is deposited on the entire surface by a chemical vapor growth method. The amorphous silicon layer 4 is made to be a single crystal by performing heat treatment. A silicon layer 5, which is made to be a single crystal in this way, has the same surface orientation as the silicon substrate 1. Thus both parts form a unitary body. Then, a capacitor insulating film 7 and a capacitor electrode 8 are formed in the trench, and a trench capacitor is formed. Since a depletion layer is not extended by the presence of the insulating film, the yielding rate of soft errors is very low even if alpha particles are inputted. A distance between the trench capacitors is restricted by forming the capacitors by utilizing the trench structure, and a high integration density can be implemented to a large extent.
