Title: Ski board
Inventor: TAIMA SHOICHI
IPC: A63C5/056
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To make snow and ice hardly stickable to running surfaces without applying wax, to ensure easy skiing and to improve gliding performance by incorporating titanium oxide into the polymers of the running surfaces at the bottoms of ski boards. SOLUTION: The materials formed by molding high-density polyethylene(PE), ultrahigh mol.wt. PE or polypropylene(PP) are usually used for the running surface materials (sole materials) of the ski boards. The titanium oxide is uniformly incorporated into such running surface materials during the stage for molding these materials. The titanium oxide to be used is preferably titanium dioxide. This titanium dioxide is preferably incorporated in the form of powder into the polymers. The amt. of the titanium dioxide to be added is specified to about 0.1 to 10wt.% of the polymers. An equally good alternative is to incorporate the titanium dioxide into the polymers, such as PE, PP, molded to a sheet form and sticking these sheets to the running surfaces at the bottoms of the ski boards.

Filed: 1987-01-12
Abstract: PURPOSE:To store the high-speed data with a frame memory through jumping storage by using a 1/8 divider circuit, an address generator, a frame counter and a memory timing control circuit. CONSTITUTION:The picture element data is written and stored into a memory at and after a picture element #1 in 8-picture element steps at the time of a 1st main scan. Then the picture element data is stored at and after a picture memory #2 in 8-picture element steps at the time of the next main scan and at and after a picture element #8 in 8-picture element steps at the time of the final 8th main scan. Therefore the vertical synchronizing signals 10 are counted by a frame counter 33. Based on this count value, a 1/8 divider circuit 36 changes the phase of the horizontal synchronizing signal 29 to divide it into 1/8 clock 38. An address generator 40 produces the address of a frame memory 39 and a memory timing control circuit 43 produces the write/read timing together with the fresh control.

Inventor: KAMO MASAYOSHI
IPC: H01F5/04
Filed: 1980-01-16
Abstract: PURPOSE:To improve the reliability of information by preventing an errorneous read of information due to a phase shift by adding a phase synchronizing pattern to a sink pattern area during modulation by an information recording and reproducing device and then by using it as phase detecting information. CONSTITUTION:After m-bit digital information (e.g. four-bit binary code) consisting of a random number of bits as a unit is modulated into n-bit digital information (e.g. eight-bit modulated code) consisting of bits more than (m) bits as a unit, the information is recorded on a medium, and to read the recording information, the n-bit information is demodulated into the m-bit information. In this case, a phase synchronizing pattern consisting of a plurality of bits is added to the sink pattern area of the n-bit information in modulation and when it is modulated into the m-bit information, the pattern is used as information for phase detection.

Title: Varnish treating method of rotary electric machine winding
Inventor: ASANO ETSUO
IPC: H02K15/12
Filed: 1978-01-18
Abstract: PURPOSE: To prevent the attachment of varnish for impregnation to a winding installed to a core onto unnecessary portions, by impregnating varnish to the windding after applying water repulsive heat-proof painting, such as, silicon varnish, etc. to the surfaces of the core, onto which varnish need not be attached.  
     CONSTITUTION: After applying water replusive heat-proof painting 4 using silicon varnish, etc. to surfaces, onto which varnish need not be attached, such as, an inner circumferential surface and an outer circumferential surface of a core 2, the whole stator 1 is entered into a varnish immersion tank 7, and varnish 8 is impregnated to a winding 3. Thus, the quantity of varnish attaching on a core surface can be reduced because varnish attaching on the core surface drops in a process of the dropping of excess drops after varnish 8 is impregnated to the winding 3 and the winding is pulled up. Using a drop impregnation method can also be useful  for the antirust to portions, onto which varnish does not attach, because heat- proof painting is also applied to the portions.

Title: Driving control method for electromagnetic proportional pressure control valve
Inventor: OYAMA HITOSHI
IPC: G05D16/10
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent adverse influence from being exerted on proportional pressure control as dither effect becomes weak in an area in which a fed current is small because of characteristics of an electromagnet driving the spool of a spool valve type electromagnetic proportional pressure control valve and an area in which the current is so large that magnetic saturation is caused when the spool is swung by applying a dither without causing any stationary friction. SOLUTION: An AC dither current is superposed in the current fed to the electromagnet 14 to swing the spool 9 to a small amplitude exerting no influence on control liquid pressure and the amplitude of the dither current is made larger in a control area, in which the ratio FSOF/I of the fed current I and the force FSOL that a solenoid generates is smaller than the other control areas, than in other control areas. The frequency of the dither current may be made low instead of increasing the amplitude.

Title: Edge-rolling method of sheet stock
Inventor: KOKUBO ICHIRO
IPC: B21B1/02
Filed: 1985-01-12
Abstract: PURPOSE:To prevent the floating of one side of a rolling stock and to improve the width accuracy of the stock by detecting the shape of a side-end face of stock and slanting a vertical roll by a proper angle to the advancing or reversing direction of stock based on the detected results. CONSTITUTION:A detector A for detecting the shape of side-end face of a rolling stock 1 and a signal processing device B, are arranged on the upstream of an edging mill D. Based on the detected shape of the side-end face, a vertical roll 2a is slanted, by an angle within a range of 5-15 deg., to the advancing direction of stock 1. When judged, based on the detected results in the degree of an assortment of said shape, that the slanting of only one-side roll 2a is insufficient, the vertical roll 2 of the other side is also slanted oppositely to the advancing direction of stock 1 by an angle of the same degree as that of the roll 2a. By this method, a component of the vector of rotating motion of the rolls 2a, 2 prevents the floating of the one side of stock 1. Accordingly, the width accuracy of stock 1 is improved.

Title: Oil pump
Inventor: SAGUCHI JIYUNICHI
IPC: F04D13/06
Filed: 1980-01-17
Abstract: PURPOSE: To prevent malfunctioning of relays without temporary locking of a relay for detecting hydraulic changes checking hydrualic changes in an oil-filled electric device by easing the flow of a cooling oil with the travelling of an impeller when starting and stopping an oil pump.  
     CONSTITUTION: When a motor 10 and electromagnets 9 are operated, with a magnetic force generated between a stator 14 and a rotor 15 of the motor 10, a holding plate 11 integral with the stator 14 turns against the resilience of springs 13 while going up. An impeller 16 normally runs with the holding plate 11 of the motor 10 after the lifting and hence a cooling fluid cooled with a cooler increases in the flow rate gradually to an inflow port 3 through a passage 19 from an inflow port 2 and comes to circulate without changing hydraulic pressure in the oil-filled electric device thereby preventing malfunctioning in relay for detecting hydraulic pressure. At the stoppage, the holding plate 11 reciprocates down to reduce the flow rate of circulation gradually. This causes no change in the oil pressure of the oil-filled electric device thereby preventing malfunctioning of the relay for detecting oil pressure.

IPC: G01N27/12
Filed: 1981-01-14
Abstract: PURPOSE:To increase detective sensibility for alcoholic vapor, and to decrease that for methane, isobutane, hydrogen and etc. by allowing effective components to be a prescribed amount of MgO, Cr2O3, SiO2 and/or TiO2. CONSTITUTION:Effective components are regulated to 45-25mol% MgO, 45- 25mol% Cr2O3, 10-50mol% SiO2 and/or TiO2. When the content of SiO2 or TiO2 is larger than this value, measurement is difficult because of too high resistance of detection element. Whereas the detective ability for gas becomes insufficient, when the content is smaller than this value. Contents of MgO and Cr2O3 are desirable to regulate to equimolar %. Sometimes constituents are formed as reaction products such as complex oxides. In this case, the range of components is expressed in terms of the above-mentioned oxide form.
