Title: Corrosion prevention of roll for continuous casting
Inventor: SATO YUJI
IPC: B23K31/00
Filed: 1987-10-19
Abstract: PURPOSE:To extend the roll service life by welding a low carbon austenitic metal to the groove root 1st layer of a roll welding part and then executing the cladding by welding of a 2nd layer and on. CONSTITUTION:The austenitic welding metal 6 contg. <=0.02wt.% carbon is formed on the 1st layer of the groove root part 6a of a roll welding part, then the cladding by welding of the welding metal 6b of a 2nd layer and on is executed. Due to the austenitic welding metal of low carbon being arranged on the 1st layer the formation of a methane with the reaction of the carbide in the welding metal and the hydrogen in the cooling water is prevented. No tear of the metal grain boundary is therefore caused with the hydrogen infilterated into the welding metal being made molecular. The hydrogen attack to the roll welding part 6a and a hydrogen brittleness type stress corrosion crack(SCC) are prevented and the roll service life is thus extended.

Title: Water jet propulsion machine
Inventor: ARATA TETSUYA
IPC: B63H11/113
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To efficiently propel a vessel by sucking water in out of the outer circumference into a spiral-shaped groove provided for the stationary spiral element, sealing it in a space between the outer wall and the spiral projection of a movable spiral element, thereby rotating the movable spiral element, forcibly moving it to the center, and thereby letting it be jetted out of an exhaust nozzle at the center of the stationary spiral element into atmosphere. SOLUTION: A space which is communicated from an inlet 2c in the spiral shaped groove of a stationary spiral element to an exhaust nozzle 2d, is partitioned by the spiral shaped projection of a movable spiral element so as to be divided into three spaces. Water filled in these spaces is similarly moved as the movable spiral element 1 is revolvingly moved. A space between the spiral shaped projection outer wall of the movable spiral element and the spiral shaped wall of the stationary spiral element is in a hermetic condition, and it can suck up water from below even if the surface of the water is located downward from the pump part of the water jet propulsion plant 5. Water flowing in from the inlet through a water conducting duct is moved to the center from the outer side, and it is jetted out of the exhaust nozzle 2d, so that a vessel is thereby advanced.

IPC: B62M6/55
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To construct the whole drive device in a small size and lessen the crank pedal spacing by furnishing a crank shaft of human power drive system, a resultant force shaft coupled with the rear wheel transmission line coaxially and rotatably with the crank shaft, a one-way clutch on the human power drive system, and a one-way clutch to transmit the electric drive system to the resultant force shaft. SOLUTION: The rotation of a motor 22 is transmitted to a resultant shaft 56 in cylindrical shape held coaxially and rotatably with a crank shaft 32 via a one-way clutch 48, planetary reduction gear 50, and gears 52, 54, and further to the rear wheel 14. The rotation given by the human power through pedals 36 is transmitted to the resultant shaft 56 via the crank shaft 32, another one- way clutch 60, and a planetary speed increaser 62, and further to the rear wheel 14. Because of coaxial installation of the resultant shaft on the crank shaft, they are not separetely located fore and aft on the bicycle body as in the conventional arrangement, and it is possible to install the human power drive system and the electric drive system around the crank shaft 32.  Because of isolated layout of the two one-way cluches 48, 60, the size across the bicycle width can be suppressed, and the crank pedal spacing can be lessened.

IPC: H02P1/32
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent power source short circuit which is to be caused by the phenomena that, even when instantaneous stop is generated during stationary operation wherein connection of the winding of a motor is a delta, a voltage is again applied after the instantaneous stop is ended, and starting is begun from the state that the connection of the winding is a star, contacts which maintain the delta before the instantaneous stop and contacts which maintain the star after the re-starting turn on at the same time. SOLUTION: In addition to a first timing circuit 761A which sets the time for continuing a star, and a second timing circuit 762 which sets a time interval for starting a delta from when the star is ended, a third timing circuit 763 which sets a delay time T3 until starting is begun after a power source is applied is installed. When contacts maintaining the delta of connection at the instantaneous stop maintains the on-state after a voltage is again applied after the instantaneous stop, the following is ensured by suitably setting the value of the delay time T3 ; the contacts forming the star connection are turned on, after arcs of the contacts maintaining the delta vanish and the contacts practically turn off.

Title: Heat insulating material and method of keeping indoor space warm
Inventor: HAYAKAWA MAKOTO
IPC: E04B1/74
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To make possible to cut off an indoor space from outside air and ensure a heat insulating effect by installing a layer containing a photo-semiconductor on the surface of a base material, making the surface of the layer hydrophilic depending on light excitation, and spreading condensed water of a moisture content adhering thereto across the surface of the layer. SOLUTION: A layer containing a photo-semiconductor such as a crystalline titanium oxide is installed on the surface of a base material, and the surface of a heat insulating material is made hydrophilic depending on the light excitation of the photo- semiconductor. In such case, if the surface layer is made of only photo-semiconductor particles, it exhibits hydrophilicity when contaminants in the environment are not absorbed, with the photo-semiconductor acting as an oxide. Also even when the top surface is made of an ordinary inorganic oxide, the oxide becomes hydrophilic when contaminants in the environment are not absorbed. And then the surface layer expels the contaminants by the light excitation of photo-semiconductor particles mixed into the surface layer, forms an absorbing water layer, and forms even water film. Therefore, discharge of indoor heat into the outdoors as infrared radiation is restrained, admitting sunlight and ensuring the thermal effect of sunlight on an indoor space.
