Title: Recording fluid and method of recording by using it
Inventor: OGAWA HIROKO
IPC: C09D11/00
Filed: 1988-02-12
Abstract: PURPOSE:To realize stable delivery of a recording fluid even under variable drive conditions or during long-term service, by dispersing a pigment wherein pigment particles of at least a specified diameter account for at most a specified proportion of the total pigment in a liquid medium consisting mainly of water. CONSTITUTION:In a recording fluid comprising a dispersion of a pigment in a liquid medium consisting mainly of water, pigment particles having a diameter of 0.6mum or more account for 10vol.% or less of the total pigment. If a larger amount of coarse particles are present in an ink, a change occurs in the ink dispersion when thermal energy is applied to the ink with a heating head, so that a foreign substance will deposit on the heated surface. An ink containing a large amount of fine pigment particles produces a dispersion stable even when thermal energy is applied, so that it hardly causes deposition. Accordingly, the use of an ink containing a pigment having the above-mentioned particle diameter can realize stable delivery even under variable drive conditions or during long-term service.

Filed: 1980-03-11
Abstract: PURPOSE: To improve yield and decrease the number of steps by calcuating the volume of the material to be rolled, forecasting its finishing size, comparing the forecasting size and the permissible tolerances of the product and controlling the rolling.  
     CONSTITUTION: Known measurement means for outside diameter, thickness and width sizes are provided to ring rolling mills, and these are monitored with a process control computer. Volume is calculated from the detected outside diameter, thickness and width sizes and based on this volume, the finishing size of the cass when rolling controlling conforming to the previous one is continued is forecast. Next, the forecast finishing size thus obtained is compared with the permissible tolerances of the final annular product. If the forecast outside diameter, inside diameter and width sizes are all in the tolerances, the rolling controlling is so made as to make the finishing allowances for the inside and outside diameters equal. Next, if part of the forecast sizes deviate from the tolerances and the other forecast sizes satisfy the tolerances, the rolling is so controlled as to decrease the finishing allowances deviated from the tolerances and increase the finishing allowances as much as to conform to the finishing allowance portions decreases in the parts where there is a margin. Next, if the outside diameter, thickness and width sizes are all in excess of the finishing allowances and deviate from the tolerances, the finishing allowances for the outside circumferential side and width are decreased to the maximum tolerance values and these parts are concentrated on the inside circumferential side.

Title: Safety device for gas instrument
Inventor: SUGANUMA RYOICHI
IPC: F23K5/00
Filed: 1990-02-08
Abstract: PURPOSE:To improve the safety of a device by installing an advancing/retracting member that advances against the force of a spring pushed by a gas instrument in parallel with an instrument knob shaft and a member that blocks the passage of said advancing/retracting member except when the instrument knob is set to a shut-off position, in a vessel-changing gas instrument safety device. CONSTITUTION:When an attempt is made to set an instrument knob shaft 4 to a shut-off position, a safety lever 7 is engaged with the instrument knob shaft 4, thereby producing oscillation. As a result, a notch 6 retracts to the position where an advancing/retracting member 5 can pass through. Therefore, when a gas vessel B is pushed into a socket 11 of a governor 2, the member 5 is pushed with the flange F so that the member 5 may advance. Therefore, the gas vessel B is serviceable since a nozzle N comes into contact with a valve opening means 20, However, when the instrument knob shaft 4 is not at the shut-off position, the safety lever blocks the passage of the member 5 so that the gas vessel may not be mounted. Therefore, this construction improves the safety performance.

IPC: H05B41/392
Filed: 1992-02-19
Abstract: PURPOSE: To regulate the illuminance of a fluorescent lamp by controlling its lamp power. CONSTITUTION: A ballast 10 is constituted of an input control section 14 for controlling power fed to a fluorescent lamp 12, a lamp driving section 16, a power command interface 28 and a control section 18. In this constitution, an external power command input 26 is compared with a calculation power level P to be internally generated, and a precontroller output voltage V is multiplied by a lamp driver current I in order to obtain a signal indicating the lamp power. Furthermore, the command input 26 is isolated by the power command interface 28. The command input signal 26 is attenuated to reduce power transmitted to the lamp 12 to thereby accomplish the diminution of light intensity of the lamp 12.  This performs substantial constant power operation in order that one ballast can be employed in various applications, and consequently, a lighting designer and an user have a high degree of flexibility.
