Title: Optical communication network device, optical transmission system and optical communication network
Inventor: SHIRAGAKI TATSUYA
IPC: H04L12/931
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To configure the optical communication network at a low cost where a failure can be quickly recovered in the optical communication network consisting of nodes through which a main signal passes as light without being converted into other forms of signals. SOLUTION: An optical transmitter 309 of a node 301 of the optical communication network transmits an OAM (control, monitor) signal at a different wavelength from that of a main signal to a photocoupler 305, where the signal is transmitted while being superimposed on a main signal. A WDM coupler 102 separates an OAM signal light to monitor it. The optical level of the main signal light is monitored by tapping part of the main signal light using a photocoupler 103. When a fault in the OAM signal light and a fault in the main signal light are detected, a fault of an optical transmission line connected to a node where the main signal light passes through as light can be confirmed at that node and a fault recovery operation can be started from a node closest to a faulty point and the fault can be quickly recovered.

Title: Play system
Inventor: MATSUDA TETSUO
IPC: A63F7/02
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent lubricity from being lowered by taking off satisfactory self-lubricious resin and sticking it on the surface of a PACHINKO ball even after sweat, dirt on hands or fat stuck on the surface is removed together with dust by arranging the resin equipped with satisfactory self-lubricity on the circulation route of a play medium interposing a polishing device. SOLUTION: Concerning PACHINKO balls 10 stored in a lower tank 5, rising force is applied by a lifting device 6 and after their surfaces are polished by a polishing device 7 in the middle, these balls are lifted through the inside of a resin pipe 8 made of polytetra-ethylene fluoride, for example, to an upper tank 1. At such a time, since the PACHINKO ball 10 reduces its outer diameter a little rather than the inner siameter of the resin pipe 8, is made spherical, made of steel and made heavy, when pushing up the ball inside the resin pipe 8, it is strongly pressed onto the inner surface of the resin pipe.  Namely, since pressure onto the surface of the resin pipe 8 is operated, the PACHINKO ball 10 shaves the surface of a wall a little in strong contact with the inner surface of the resin pipe 8 and polytetra-ethylene fluoride is stuck on the surface of the ball 10 so that lubricity can be improved.

Title: Counter-rotating propulsion device for vessel
Inventor: HARADA HIROSHI
IPC: B63H5/10
Filed: 1994-10-17
Abstract: PURPOSE: To reduce the occurrence of oscillation by letting the maximum overlapped area when a front side and a rear side blade are projected in the direction of each rotating shaft, be curved to the rear side in the direction of rotation in such a way that the above-mentiond maximum overlapped area and the projected area of the front side blade in the xial direction should be formed into a specified proportion. CONSTITUTION: Counter-rotating propellers 12 in the counter-rotating propulsion device are made up of a front and a rear propeller 27 and 28, and the front and rear propellers 27 and 28 are curved to the rear side in each rotating direction so as to be formed into, what is to say, a schew form each. The area of an overlapped portion (shadowed section A) when both the propellers 27 and 28 are projected in the direction of each rotating shaft, shall be less than 80% of the projected area of the front propeller 27 in the direction of its rotating shaft, and is set at for example, 12% in this case.  When an overlapped area is large, for example, if both the blades at the surface of water are overlapped behind a rudder 5, almost all the blades are interrupted by the rudder 5, oscillation becomes large because of unbalance in water flow between the blade at the surface of water and the blade at the depth of water. On the contrary, when the overlapped are is small, the occurrence of oscillation can be reduced.

IPC: H04B7/26
Filed: 1994-10-17
Abstract: PURPOSE: To enable a simultaneous multi-address communication, to improve working efficiency and to secure safety management by arranging portable radio equipment in each site, performing transmission with a transmission frequency different from each other and performing reception with the frequency other than its own transmission frequency by each radio equipment. CONSTITUTION: Radio transmission from the portable radio equipment QU1-4 arranged in each site are received by the four tuners 8e of the radio equipment QU5, and they are amplified by pre-amplifiers 9e, and mixed by a mixing circuit 10e, and moreover, they are amplified by a power amplifier 11e, and call contents voice-inputted by the radio equipment QU1-4 are superimposed on them, then, they are outputted in voice from a speaker 5e. Therefore, the call content of each radio equipment can be recognized by the radio equipment QU5 regardless of the period of transmission/non- transmission. Since the radio equipment QU5 is formed in the same constitution as that of the radio equipment QU1-4, the call content can be recognized by each radio equipment.  In such a way, the simultaneous multi-address communication is attained, therefore, an effect for a report with respect to the progression of work between each site and communication for the confirmation of safety, etc., can widely be expected.

Filed: 1991-09-30
Abstract: PURPOSE:To obtain uniformly boiled rice by providing a revolving mechanism, which is connected with an inner pan, on the base of a body, and an inclining mechanism which inclines the inner pan on revolution for even temperature distribution of water in the inner pan. CONSTITUTION:As rice boiling starts and water temp. in an inner pan 7 rises, a drive motor 9 rotates the inner pan 7 through a connecting mechanism 8. A pair of inclination motors 22 are driven simultaneously, and a cam 25 is driven to gradually press down a pair of leg shafts 26. The pressed down leg shafts 26 incline a body 1, and when the body 1 inclines at 15-20 degree angle, the inclination motors 22 stop revolving. Thus, rice and water in the inner pan 7, which rotates while inclining, are properly moved and heated evenly. After a given time of inclination and rotation of the inner pan 7, the inclination motors 22 make a reverse rotation to return the body 1 to horizontal and the drive motor 9 stops revolving, and rice boiling in a horizontal state is continued again.

IPC: F23Q9/08
Filed: 1983-12-31
Abstract: PURPOSE:To indicate the state of ignition without delay, by decreasing the returning distance of an igniting member, by closing a pilot valve by a small amount of pivotal movement of the primary cam to the returning direction. CONSTITUTION:A pilot lever 43 is operated by the primary and the secondary cams 21 and 22. In the latter half of an igniting operation, a pilot valve is held in the open state by the primary cam 21, at the same time a main valve is held in the open state by locking the secondary cam 22. The pilot valve is designed to be closed by a small amount of pivotal movement of the primary cam 21 to the returning direction, so that the returning distance of an igniting mechanism 1 is made short. With such an arrangement, the state of ignition of a burner can be indicated without long delay.

Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a nano-structure memory element, which has a drain, a source and a channel and a region, in which electrons are stored, and in which the device has corresponding discrete threshold voltage, by composing the memory element of a nano-crystal formed onto a first insulator layer, electrically floated and electrostatically coupled with a semiconductor channel by Coulomb interruption and a gate electrode formed onto a second insulator layer.

Consequently, when ten electrons or holes are stored, the shift of threshold voltage at 1.7V is generated. Accordingly, words in two bits or more of width can be stored in one memory-cell as the function of the number of electrons stored, thus largely increasing bit-pack density.
