IPC: F16H15/38
Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a toroidal type continuously variable transmission in which a little change in the permissible range of the tilting rotation angle before and after the deformation of a link and a trunnion enables regulating a tilting rotation angle as designed, and no consideration about tolerance of the permissible range of the tilting rotation angle at the design phase allows widely setting a range of change gear ratio.

Title: Electron beam irradiator
Inventor: KATAOKA YOSHITSUNE
IPC: A61L2/08
Filed: 2000-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an electron beam irradiator which can withstand a high- output electron beam irradiation. SOLUTION: Since a disk-like window 12 is rotated by a rotating mechanism 13, heat is conducted to other areas of the window 12 even if heat is generated due to the interaction between an electron beam and atoms of a metal used for the window 12 when the electron beam passes through the window 12. In other words, the disk-like window 12 itself functions as a radiator plate. As a result, the lifetime of the window 12 is prolonged by preventing it from melting due to the heat. Even if a high-output electron beam is applied, moreover, the window 12 can withstand by being cooled sufficiently because an exposed part of the window 12 is cooled by a cooling means 18.  In addition, the strength of the window 12 can be enhanced and the costs of it can be decreased by making only an area shaped like a ring in the window 12 which is opposite to an irradiation aperture 4 of the electron beam irradiator in a metal thin film which allows the electron beam to pass through.

Filed: 2000-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent overlooking or a misunderstanding from occurring by notifying a game player of it when a specified condition to delay the completion of a round has been established. SOLUTION: When a switching condition is established during a period while a technical intervention is possible in one round regarding a game machine such as a pachinko machine or an arranging ball machine, the frequency of the condition establishment is counted up. The frequency of the condition establishment (totaled value) increases by one as time passes to t54, t56 and t58, and it is understood that the switching condition has established three times for a big winning game of this time. When the big winning game is completed at time t62, during a period from time t64 to time t66, the frequency for the success of a technical intervention for the big winning game of this time (in concrete, the frequency of the condition establishment) is displayed on a pattern displaying apparatus, or the applicable frequency is notified by sound from a speaker.  By the notification by such dramatizations, a game player less overlooks while paying attention to other subjects, and less misunderstands like that the game content is the same as a conventional pachinko machine.

Filed: 2000-12-20
Abstract: PROBLEM TO BE SOLVED: To easily mend deteriorated insulation properties of a cable conductor. SOLUTION: Hygroscopic materials are arranged inside cable terminals containing cable conductors composed of several hundreds of pairs. Since the pressure of steam inside a cable terminal is lowered by these hygroscopic materials, and a water film between cable conductors 1a, 1b become thin, the water film is divided into a water film 10a on the surface of the cable conductor 1a and a water film 10b on the surface of the cable conductor 1b, and an ion insulating property between the cable conductors is kept high. By using wood or a high molecular hygroscopic material as a hygroscopic material, the life of the insulation property of each cable conductor with respect to thermal oxidation is improved, and in addition an excellent hygroscopic and dehumidifying characteristic is obtained.

Filed: 2000-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain an optical amplifier which prevents signal light of remaining wavelengths from excessively being outputted when the number of channels of multiplexed signals abruptly changes owing to troubles, etc., in a terminal station. SOLUTION: A dummy light (saturation light) source 40 emits dummy light and a directional coupler 11 multiplexes the dummy light with a light signal; and the light signal and part of the dummy light outputted from the directional coupler 11 are branched and outputted to a directional coupler 12.
