Patent JP-S57193780-A (JP)
Title: Axial flow hydraulic machine
Inventor: OOGAWARA TAKASHI
IPC: F03B3/12
Filed: 1981-05-25
Abstract: PURPOSE:To have a small-sized runner with high efficiency by bending the runner in its middle concentrically with the runner boss. CONSTITUTION:A runner blade 5 is installed on the runner boss 1 firmly or rotatably, where the blade is bent in its middle. In this case, this bending of blade 5 is made concentrically with the runner boss 1 so that rotation of the blade does not cause this bending point to encounter the resistance of water stream. The angle of bending shall be such that the blade approaches the runner supporting side. In comparison with a straight runner, the overall length of this blade increases accordingly the area of blade, which contributes to generation of lifting force, and the torque will thus increase.

Inventor: OSANO NAGATO
IPC: G03F7/40
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the surface of a substrate exposed to the opening of a black matrix formed by exposing and developing a resin layer from getting ink-repellent and to improve the adhesive property of coloring ink to the surface of the substrate so as to improve reliability by heating the black matrix under reduced pressure. SOLUTION: The black matrix having the opening is formed by forming and temporarily curing the resin layer on the substrate, and exposing and developing the resin layer. In a post-baking stage, the substrate 1 where the black matrix is formed is inserted in a reduced pressure chamber 32 where an insertion port 34 is formed and the black matrix is heated under reduced pressure to be hardened by using a hot plate 35. Post-baking is performed by heating under reduced pressure, a volatile component generated from the black matrix is prevented from being stuck to the exposed surface of the substrate. Therefore, the ink 1 is surely stuck to the substrate 1 in a next ink sticking stage. The necessary time is made shorter by heating under reduced pressure than by normal pressure heating.

Title: Air conditioner for automobile
Inventor: TAKAHASHI EIJI
IPC: H02P1/18
Filed: 1981-05-27
Abstract: PURPOSE:To reduce the capacity of a transistor by delaying the rise of a base voltage of the transistor connected in series with a fan motor when the motor is started. CONSTITUTION:Since the collector current of a transistor T1 is partly flowed through a condenser C1 and a resistor R3 to an earth when a fan switch SW is closed ON, the voltage at the point F does not become high until the condenser C1 is charged. Accordingly, the rises of the base voltages of transistors T2, T3 are delayed, and the collector currents of the transistors T2, T3 at the time of starting a fan motor M are reduced. In this manner, the transistors of small capacity can be used.
