Patent JP-H04171202-A (JP)
Title: Steam turbine power generating plant
Inventor: OMORI TATSURO
IPC: F01K7/22
Filed: 1990-11-06
Abstract: PURPOSE:To increase the internal efficiency of a steam turbine, and also reduce centrifugal stress and thermal stress, by driving a steam turbine into which main steam whose temperature and pressure are higher than normally employed levels is introduced at first, so that the steam turbine drives a power generator on a shaft which is separate and independent from a group of other turbines. CONSTITUTION:A power generator 6a is directly coupled to a super-super-high- pressure turbine 9b, whereas the shafts of turbines from a super-high-pressure turbine 2a through a low-pressure turbine 5 are coupled together in series to form a train, to which a power generator 6b is coupled in series. Since the super-super-high pressure turbine 9b is installed on an independent shaft (to which no other turbine is coupled), its thermal elongation does not affect a high-pressure turbine 3, a medium-pressure turbine 4, and the low-pressure turbine 5, and also axial clearances among the high-pressure turbine 3, the medium- pressure turbine 4, and the low-pressure turbine 5 can be reduced. This allows to reduce leakage loss. Furthermore, thermal stress due to turbine start-up can be reduced by holding the super-super-high pressure turbine, which is apt to produce high thermal stress, always at a high temperature.

Patent JP-H04172083-A (JP)
Title: Driving method for photoelectric converter
Inventor: OSADA YOSHIYUKI
IPC: H04N5/374
Filed: 1990-11-06
Abstract: PURPOSE:To reduce the after image of a photoelectric converter by changing the inter-terminal voltage of a photodiode during the duration period of a reset pulse signal for resetting a storage charge inputted to a switching element. CONSTITUTION:When resetting the storage charge, the inter-terminal voltage of the photodiode is set (a reset A) by a pulse width shorter than a reset pulse width so as to impress a reverse bias bigger than storage initial voltage, next the photodiode is set (a reset B) at a storage initial voltage V0. That is, at the reset A, a depletion layer is widened until the position of the depletion layer end, and at the reset B, an effective electric field exists even at the position of the depletion layer end. Therefore, the trapped electric charge in the vicinity of the depletion layer end is emitted quickly. Thus, the after image is reduced drastically.

Title: Electrode support section for discharge lamp
Inventor: YAMAGUCHI MAKOTO
IPC: H01J61/36
Filed: 1987-11-30
Abstract: PURPOSE:To prevent the characteristic from becoming unstable due to the nonuniform thermal load applied to a translucent ceramic tube at the time of lighting by coupling a circular body made of ceramic at the appropriate position of a metal tube located on the inside of an end cap to constitute an electrode support section. CONSTITUTION:A large-current discharge lamp is provided with an electrode body 6 at the inner end section of a metal tube 4 and hermetically closed at the outer end section of the metal tube 4 and has a ceramic circular body coupled at the appropriate position of the metal tube 4 located on the inside of an end cap 2. This circular body 7 is shaped to reduce the heat capacity from the inside of the diameter direction toward the outside, and its periphery is brought into contact with the inner wall of the translucent ceramic tube 1. As a result, the portion in contact with or fixed to the metal tube 4 is liable to absorb or conduct the high temperature of the metal tube at the time of lighting a discharge lamp, on the other hand the portion in contact with the inner wall or the translucent ceramic tube 1 reduces the heat conduction from the metal tube 4 to the translucent ceramic tube 1. The deterioration in characteristic caused by the thermal stress of various sections of a luminous tube at the time of lighting can be thereby prevented.

Title: Alkali storage battery
Inventor: YUASA KOJI
IPC: H01M50/42
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To restrain lowering capacity maintenance rate due to advancement of battery service characteristics and self-discharge by employing a woven cloth essentially consisting of a polyolefin-based resin graft-polymerized by an hydrophilic compound having a carboxyl group in its surface layer as a separator, a non-woven cloth or a porous membrane, and restraining the carbonate radical quantity in a battery to a specific value or less. SOLUTION: A carboxyl group deviating in a separator or existing in an incomplete graft polymerized state is oxide-decomposed by a battery charging and discharging to form a carbonate radical. This carbonate radical oxidizes a hydrogen absorption alloy that is a negative active material, making this inactive and lowering service life characteristics. Therefore, conditions during graft processing are optimized for a separator surface, a generation source of the hydrocarbon root generated in the battery is restrained, and the hydrocarbon root quantity in the battery is restrained to 150 mg or less per battery capacity of 1 Ah. In addition, a hydrophilic compound having a carboxyl group is an acrylic acid or the like, and its graft rate is preferably 4 to 16 wt.%.
