Title: Disk housing magazine and disk player
Inventor: UMEZAKI KIYOSHI
IPC: G11B17/26
Filed: 1992-09-29
Abstract: PURPOSE:To simplify the constitution of the player and to miniaturize it without changing modes of a magazine at the playing time by moving a tray having a slim part by a prescribed amt. in an approximately vertical direction to a main surface of a disk. CONSTITUTION:Projecting parts 2a and 2b of the trays 2 are engaged with guide grooves 1a in stepwise pattern in a magazine case main body 1, so that the trays 2 are housed in the main body 1 at equal intervals. Then, parts 2d and 2e are slimmed. Then, when a prescribed tray 2 is selectively drawn from the main body 1, the tray 2 is regulated by the guide groove 1a and is moved, and when the tray 2 is moved to a step part, the tray 2 is moved downward by a prescribed amt. Since each tray 2 is slimmed, no interference with adjacent tray(s) takes place in a position where the tray 2 is moved in an approximately vertical direction.

Title: Organic electrolytic battery
Inventor: SAKAMOTO HIDEO
IPC: H01M4/06
Filed: 1988-10-14
Abstract: PURPOSE:To reduce the inner resistance increase in the latter half of discharge and enable the effective use of the discharge capacity to the end by supporting the separator outer circumferential part between a negative electrode and a gasket. CONSTITUTION:A separator 3 is disposed in such a manner as to be supported between a negative electrode can 1 and a gasket 7. Namely, as the separator 3 is not fixed, the separator 3 follows the volume swelling of a positive electrode 4 accompanied by the discharge progress resulting in less compression of the separator 3, and the solution holding property of electrolyte is less injured. Thus, the electrolyte is held in the separator 3 even at the discharge closing stage, never causing the reduction in ion conductivity between the positive electrode 4 and the negative electrode. Hence, the discharge performances such as inner resistance increase and discharge voltage reduction at the discharge closing stage are improved, and the capacity is made effectively usable.

IPC: C21D8/12
Filed: 1994-10-25
Abstract: PURPOSE: To produce a silicon steel sheet of extremely high magnetic flux density by specifying the rolling condition in cold rolling when a silicon steel slab of relatively low silicon is hot/cold rolled to produce a nonoriented silicon steel sheet. CONSTITUTION: After a silicon slab of <=7.00% Si and relatively low content is hot rolled, e.g. to 2.7mm thickness, the slab is made to a cold rolled sheet of 0.55mm thickness by the cold rolling of two times including intermediate annealing, further is finished to the final sheet of 0.50mm thickness by skin pass after finish annealing and is subjected to final strain relieving annealing. The first cold rolling in this rolling process is executed under the condition that the parameter M defined in the equation I satisfies 1<=M<=7.0. Or rolling is executed so that (mi) defined in the equation II in each pass of the first cold rolling satisfies 0.1<=(mi)<=5.0 for at least one pass, thus, the nonoriented silicon steel sheet of extremely high magnetic flux density after finish annealing and strain relieving annealing is produced.

IPC: H05B33/04
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a structure of an organic electroluminescent element which can be automatically recovered from a short circuit defect. SOLUTION: This organic electroluminescent element includes a laminate 50 having a structure in which an organic luminescent layer 10 made from an organic compound is sandwiched between a cathode K and an anode A opposing each other; a hermetic container 60 accommodating the laminate 50 and shutting off outside air; and a gas 90 sealed in the hermetic container 60. The gas 90 is composed chiefly of a chemically inert gas, with oxygen gas added thereto in a concentration of 0.0001 to 20%. The thickness of the organic layer 10 sandwiched between the cathode K and the anode A is about 100 nm, and whiskers or the like may form between these electrodes, often leading to a short circuit defect. Inclusion of oxygen gas in the sealed atmosphere allows aging to cause whiskers causing such a defect to oxidize and lose conductivity, to thereby allow recovery from the short circuit defect.

Title: Insulating film pinhole detecting device for insulating film steel plate
Inventor: KUNINAGA MANABU
IPC: G01N27/92
Filed: 1989-10-06
Abstract: PURPOSE:To highly accurately detect a pin hole with the same inspection sensitivity continuously to the overall width of a film by arranging electrodes on an insulating film on the surface of a steel plate at a fine interval and applying a high voltage between the electrodes and the steel plate. CONSTITUTION:The steel plate 1 provided with the insulating film 2 comes into contact with a steel roll 3 for conveyance and the electrodes 4-a and 4-b are installed on the film 2 opposite the roll 3 across the fine gap. The high voltage is applied between the steel plate 1 and electrodes 4-a and 4-b through the roll 3. Then when the applied voltage is higher than a discharging voltage in air, a discharging current flows. This discharge current is detected by a detector 7 to detect the pinhole. When the distance between the steel plate 1 and electrodes 4-a and 4-b is larger, no discharge is caused although the pinhole is present, but when the gap is narrow, discharge is caused by dielectric breakdown even at a part where the pinhole is not present. Here, the thickness of the steel plate 1 is measured by a thickness measuring instrument 10 and an electrode upward/downward moving device 9 of an air cylinder, etc., is operated according to the measured thickness to control the electrodes 4-a and 4-b and the steel plate 1 to a constant interval.

Filed: 1986-10-31
Abstract: PURPOSE:To measure magnetic characteristics of an as-cast amorphous material over its overall length and to guarantee the quality when it is used as an iron core by tensing the amorphous alloy material lengthwise. CONSTITUTION:The as-cast amorphous alloy material 1 is unwound from a payoff reel 2, sent to a tension applying device 4 through a bridle roll couple 3, and taken up around a take-up reel 5. On this conveyance path, the magnetic characteristics of the material 1 are measured while constant tension is applied. When the magnetic characteristics of the material 1 which are detected by a measuring instrument 6 do not reach a prescribed value, a part where the magnetic characteristics are low is cut away by a shearing machine 7 and the material is rewound around a troidal iron core, D type iron core, etc., and machined to obtain a product having stable magnetic characteristics. Further, the surface roughness of the as-cast material is measured continuously and an estimated value regarding magnetic characteristics after annealing which are obtained from the as-cast magnetic characteristics is corrected with said measured surface roughness to improve the measurement accuracy of the magnetic characteristics.
