Title: Information recording/reproducing device
Inventor: TSUCHIYA YOSHIJI
IPC: G09C1/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To shorten a scan time from receiving a recording command, a reproducing command to ending recording/reproducing of information by coding recording information during an acceleration period of a relative scan between a recording medium and a head part at an information recording time. SOLUTION: An MPU 33 controls a card transfer motor 37, and accelerates an optical card 1 from a stop state and starts relative movement between the optical and an optical head in the track direction. The MPU 33 reads out the data stored in a RAM by one track much, and transfers them to a coding/ decoding circuit 42 to code the recording data by using a code key. The MPU 33 monitors its relative movement speed while the optical card 1 and the optical head 30 are relatively moved in the track direction to judge whether or not the relative movement speed becomes a fixed level. When becoming the fixed level, the MPU 33 controls respective parts to read track numbers.

Title: Flame holding device for heat exchanging
Inventor: IGARASHI KAZU
IPC: F23D14/16
Filed: 1985-03-29
Abstract: PURPOSE:To contrive to miniaturize a heat exchanging part and not to require a long and large burning chamber for preventing incomplete burning by a method wherein a porous object provided with many heat transfer passages communicating a liquid supply header with a liquid exhaust header is arranged via a narrow space over a heat transfer passage group provided between each heat transfer passage. CONSTITUTION:An object to be heated is transferred through a heat transfer passage 5 communicating a liquid supply header 3 with a liquid exhaust header 4. A premixed gas supplied from the lower side is passed toward the upper side through a small clearance 7 of a heat transfer passage group, introduced to a space between a heat transfer passage group A and a porous object B, then, ignited and burnt, a burning exhaust gas is exhausted by passing upward. The heated porous object supplies the heat to the heat transfer passage group, heats the object to be heated, and raises the object temperature. Meantime, the heat transfer passage group is cooled by a liquid to be heated transferred through the heat transfer passage, accordingly, the temperature rising of a premixed gas is restrained at lower level than an igniting temperature, thus, the generation of a backfire is obstructed. The porous object is heated at all time, therefore, the premixed gas is burnt perfectly, also the blow-off of a flame is prevented.

Title: Recovering method for electron emission material of cathode for electron tube
Inventor: SANO KINJIRO
IPC: H01J1/14
Filed: 1987-03-20
Abstract: PURPOSE:To realize a decrease in cost of an electron tube by utilizing difference between the quantity of alkaline earth metallic ions dissolving into an organic solvent solution and that of scandium ions dissolving into the organic solvent solution so that recovery of scandium oxide is performed. CONSTITUTION:After residues of an electron emission material solution, with which a cathode has not been coated, are dissolved, a solvent extraction means by an organic solvent solution is used to reversely extract scandium nitrate from the organic solvent solution. Thereafter, scandium oxalate converted from this scandium nitrate is further purified into scandium oxide and recovered. Scandium oxide which is especially expensive, out of residues of the electron emission material solution with which the cathode has not been coated, can be separated and recovered to be reusable as a raw material of the electron emission matter, and so a large decrease in cost of the electron tube can be realized.

Title: Heat accumulating material
Inventor: NOMURA KAZUO
IPC: C09K5/06
Filed: 1981-04-30
Abstract: PURPOSE: To provide a heat accumulating material prevented from being supercooled, by adding as a nucleator hydrated strontium acetate or barium acetate to calcium bromide hexahydrate.  
     CONSTITUTION: As a nucleator for preventing supercooling, strontium acetate hadrate and/or barium acetate are added to calcium bromide hexahydrate. When the nucleator is added in an amount exceeding its solubility to calcium bromide hexahydrate, the nucleator present in the solid form acts as a nucleus when CaBr 2 .6H 2 O crystallizes, so that the crystallization can be initiated. Optionally, a thickening agent, etc. may be added to improve the dispersion of the nucleator. Generally, when ovules becomes larger than a critical crystal nucleus radius, they grow up to crystal nuclei, but it is considered that as the energy gap of the CaBr 2 .6H 2 O is so wide when the ovules become larger than the critical crystal nuclear radius that it suffers significant supercooling. It is considered that the nucleator serves to minimize this energy gap.

The small distance referred to above between the surface of the contactor 3b and the periphery of the grinding wheel 2 corresponds to the depth of a groove to be formed in the outer surface of a work W. An arm 1 is fallen in a horizontal state toward a shaft 4, and the grinding wheel 2 is placed on the work W. A groove is formed in the outer surface of the work W by the peripheral portion of the grinding wheel 2 to a depth at which the contactor 3b comes into contact with the outer surface of the work W. As the grinding operation progresses, work W is rotated in accordance with the rotation of a pulley 4f, and a screw 5a is also rotated in accordance with rotation of a pulley 5b, to move a shaft 4, i.e. the work W to right. Thus, a spiral groove is formed in the outer circumferential surface of the work W by a grinding wheel.
