Title: Cooling steam control method for gas turbine combustor
Inventor: OUCHI KUNIO
IPC: F02C7/18
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of cooling steam and suppress its mixing with combustion air. SOLUTION: Signals are input to a control device 1, which signals are respectively sensed by a pressure sensor 6 of a cooling steam supplying system, a combustor 12, an outlet steam temperature sensor 7, and a sensor 8 of steam pressure of a cooling passage 14. The control device 1 is so operated as to apply bias to the signal from the steam pressure sensor 8 during starting and loaded operation. In order to obtain the steam pressure a little higher than air pressure in a casing, a steam amount to be flowed into the cooling passage 14 is controlled via a flow amount control valve 4, and the pressure of the steam to be supplied is controlled via a flow amount control valve 2. After stopping a gas turbine, the control device 1 is so operated as to open an opening/closing valve 5. Dry air is flowed into a steam cooling system, for preventing generation of drain.  It is thus possible to suppress leaked steam from mixing with combustion air during starting and speed-up, and eliminate instability of combustion.

Title: Pattern formation of superconductor circuit
Inventor: MATSUI SHINJI
IPC: H01L39/24
Filed: 1987-09-30
Abstract: PURPOSE:To simplify the formation of a circuit pattern, by a method wherein a local selective doping is performed on a high-temp. ceramic superconductor by ion (except oxgen and fluorine ions) implantation to destroy the crystallinity of the selected doping parts and turning those part to non-superconducting ones. CONSTITUTION:A Y-Ba-Cu-O or other ceramic superconductor is formed on a substrate 11 by magnetron sputtering and a resist mask 13 is formed on the thin superconductor film 12. Then, the crystallinity of implanted areas 14 is destroyed by ion (Ne<+>, etc.) implantation (a) to make the areas non- superconducting. The larger is ion implantation dose, the heavier is damage to the crystal and the lower is a critical temperature. This means an ion implan tation dose can control a critical temperature. Next, the resist mask 13 is re moved by oxgen plasma etching (b). As described above, a superconducting pattern is formed by ion implantation.

Title: Pachinko game machine
Inventor: NAGATA SATOSHI
IPC: A63F7/02
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To inform a player of a standard as to whether a big hit condition will soon occur or not. SOLUTION: During a game, a cycle number of establishment of such a condition that a display on a special pattern display part 14 indicates the so-called missing check-mate condition in which the one point of the display is different, is counted by a control circuit 51, and this missing check-mate condition is indicated on a missing check-mate cycle number indicating part 14b. If the cycle number of the missing check- mate condition exceeds a predetermined value R0, a predetermined value is displayed on the missing check-mate cycle number display part, but no value exceeding the predetermined value is displayed thereon. During a game, if the game machine falls in a big hit condition, the cycle number of the missing check-mate condition is set to zero.  Thus, the player can simply know a cycle number of a missing check-mate condition which gives a direct standard for occurrence of a big hit condition, and accordingly, the player's enthusiasm in game can be enhanced. Further, when the cycle number of the missing check-mate condition exceeds the predetermined value, the predetermined number is directly displayed, and accordingly, it is possible to prevent the profit on the Pachinko parlor side from greatly lowering with no risk of extremely performing selection of game machines.
