Title: Level shift circuit
Inventor: SHIMIZU YASUHIDE
IPC: H03K19/0185
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To provide the level shift circuit with a small number of components, a simple structure and a small through-current. SOLUTION: The level shift circuit 10 is configured with series connection of P channel transistors(TRs) 11, 12 and an N channel TR 13. Gates of the P-channel TRs 11, 12 and the N channel TR 13 are connected in common to form an input and the source and the drain of the P channel TR 12 and the N channel TR 13 are connected to form an output. When a signal with a logic level at which the N channel TR 13 is conductive is received, a voltage drop by a through-current going to flow through the N-channel TR 13 and an ON- resistance of the P channel TR 11 acts like a negative feedback to the P channel TR 12 so as to bring the P channel TR 12 close to an off-state thereby reducing the through-current.

Title: Preparation of carbonated water
Inventor: KUMADA YOSHIMI
IPC: A23L2/00
Filed: 1985-01-16
Abstract: PURPOSE:To allow water to absorb a large amount of carbon dioxide, by providing an orifice on the way of the conduit connecting a water supply source and a calcareous water reservoir and connecting a carbon dioxide pipe to the downstream of the orifice. CONSTITUTION:When a water feed solenoid valve 3 is opened, water passes through an orifice to be reduced in pressure and passes through a conduit 2 filled with carbon dioxide, while accompanies turbulent flow action, to absorb carbon dioxide during this period. At this time, carbon dioxide is sucked into the conduit 2 by the ejector action of flowing water passing through said conduit 2 to promote the increase in gas content of carbonated water. The increase in the internal pressure of a water reservoir by the inflow of carbonated water leads out carbon dioxide to the conduit 2 from a pressure equalizing pipe 6a to substitute the same with carbonated water and keeps internal pressure during the manufacturing of carbonated water constant and enhances the dissolution of carbon dioxide in the conduit 2. By this method, calcareous water with a high gas volume can be prepared even if water feed pressure is low and, therefore, the safety degree to the damage of an equipment material is increased.

Filed: 1988-01-14
Abstract: PURPOSE:To reduce the cost of production and to improve heat resistance by calcining net-like glass fibers which are subjected to an acidic treatment to contain SiO2 at specific weight % or above and further, shrinking the fibers at prescribed % of heating shrinkage rate. CONSTITUTION:The inexpensive net-like glass fibers having a low SiO2 content are immersed in a soln. prepd. by adding a catalyst to an acidic soln. of hydrochloric acid, nitric, acid, etc., and the content of impurities such as CaO and MgO therein is decreased by controlling the temp., time and soln. concn. to increase the SiO2 content to >=75wt.%. The net-like body of such glass fibers are subjected to a calcination treatment by which the glass fibers are shrunk in a 2.5-15% heating shrinkage rate range. Since the inexpensive glass fiber material having the low SiO2 content is used as a raw material, the production cost of the filter is reduced. Since the SiO2 content is increased to >=75% and the material is shrunk, the heat resistance of the filter is improved.
