Title: Optical recording and reproducing method for optical card
Inventor: FUJIMOTO MAKOTO
IPC: G11B25/04
Filed: 1986-11-11
Abstract: PURPOSE:To realize a high recording density equal to an optical recording medium except a general optical card by charging a laminate film, cutting and removing a sealed part, peeling the charged laminate film by an electrical attraction force and recording and reproducing information in an optical recording member. CONSTITUTION:After the laminate film 2 is charged, the sealed part 3 is cut and removed, then, the charged laminate film 2 is peeled by the electrical attraction force, thereafter, the information is recorded and reproduced on the optical recording member 11, so that the record surface of the optical card is protected by the laminate film 2 and an external flaw or the adhesion of dust is received by the laminate film 2. Accordingly, except at the time of mounting in a writer or reader, the card surface is constantly maintained in a laminated state. Thereby, the high density recording and reproduction can be attained.

Title: Automatic lock releasing device of mobile shelf
Inventor: MORI TAKAMI
IPC: A47B53/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To release the lock state of a locking mechanism in a mobile shelf when a vibration in a front and rear direction is added to the mobile shelf without releasing it even when the vibration in a left and right direction is added in a automatic lock releasing device. SOLUTION: The lock mechanism 2 is provided with a lock member 22 which is engaged with a driving power transmitting mechanism 4 which transmits the rotary force of the handle 8 of the mobile shelf 3 to running wheels so as to prevent the rotation of the running wheels and a lock operating rod 18 which permits the lock member 22 to selectively move to an engagement position and a non-engagement position as against the driving power transmitting mechanism 4 by an external operation. Then, the lock operation rod 18 of the lock mechanism 2 is operated by the movement of a mobile body which is movable in a front and rear direction when the vibration is added to the mobile shelf 3. Therefore, the lock member 22 is moved to the non-engagement position and the engagement of the lock member 22 as against the driving power transmitting mechanism 4 is released.

Title: Magnetic disk device
Inventor: KISHIMOTO TETSUYA
IPC: G11B33/14
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a magnetic disk device by fitting plural kinds of gas absorbing agents in a sufficient amount as the whole into air gap parts of the side faces of a magnetic head position mechanism while dividing them into plural parts to efficiently eliminate gases existing in the vicinity of the head without being affected by air flow. SOLUTION: Plural kinds of gas absorbing agents 1 such as activated carbon and so forth in a sufficient amount as the whole, are fitted into the air gap parts of the side faces of the positioning mechanism 3 of a magnetic head 2 while being reduced in amount by quadri-secting and being made thin in thickness. Consequently, the total area of wind receiving parts of the agents 1 becomes large and the gas absorbing rate of the agents 1 is increased and also the pressure drop of the agents reversely proportional to the square of the thicknesses is reduced and the agents 1 can cope with many kinds of gases. For this purpose, the absorbing agents 1 are always set on the upstream side from a magnetic disk 4 and then the setting of an air flow path is not required particularly, and at the same time, the agents 1 become to hardly receive the influence of a full-track seek. Thus, the reliability of the device is improved by efficiently eliminating gases existing in the vicinity of a head 2 without being influenced by air flow.

Title: Interchangeable lens for camera
Inventor: MATSUYAMA SHINICHI
IPC: G02B7/08
Filed: 1987-10-22
Abstract: PURPOSE:To prevent the misalignment of a focused state caused by a misoperation of a power focus switch by determining the power focus permission/inhibition by a power focus permitting signal or a power focus inhibiting signal from a camera body without determining it by a lens side. CONSTITUTION:The power focus permission/inhibition is not determined by a lens side but determined by a power focus permitting signal or a power focus inhibiting signal from a camera body 28. Accordingly, even if an auto/manual changeover switch 18 is in an auto state, the power focus becomes possible, depending on specifications and a state of the camera body 28, or even if the auto/manual switch 18 is in a manual state, the power focus becomes impossible, depending on specifications and a state of the camera body. In such a way, the misalignment of a focused state caused by a misoperation of a power focus switch is prevented.

Title: Thin battery
Inventor: MATSUMOTO KENJI
IPC: H01M4/06
Filed: 1985-11-27
Abstract: PURPOSE:To make performance uniform and improve adhesion of positive active material with a current collector by making ink with a positive mix and organic solvent, inking a current collector, and drying to form a positive electrode. CONSTITUTION:A positive mix ink is applied to a positive current collector 2 by screen printing, and dried to form a positive electrode 4. The current collector 2 is required to be stable against positive active material, electrolyte, and organic solvent. therefore, for example, a film obtained by laminating an aluminum foil on a conductive film prepared by dispersing carbon filler in polyolefin resin is used as the current collector. Thereby, adhesion of positive active material with current collector is increased and performance of the battery is made uniform.

Title: Card
Inventor: WAKAYAMA TOSHIFUMI
IPC: B29C45/26
Filed: 1987-10-22
Abstract: PURPOSE: To enable the volume production of a card without printing displacement by a method wherein a card is formed by a plastic injection molding or an injection molding and the card is punched out from an original plate on the surface of which images are printed so that the plastic injected boss may not be contained. CONSTITUTION: An original plate is thinly plastic injection molded. A card 11 is formed by punching the original plate so that a concave section 12 for housing each IC chip may be contained. This enables the simultaneous volume production of a single original plate. When cutting out the IC card 11, the predetermined printing is conducted on the surface of the original plate. That is, the printing is performed on the position responsive to each card depending on the state of the original plate. In this case, many cards can be printed by one print and a labor of printing cards one by one can be saved. The volume production becomes possible as a result, and printing displacements and misprints can be decreased as well.

Title: Idle rotational speed controlling method of internal combustion engine
Inventor: TAKAHASHI MINORU
IPC: F02D41/16
Filed: 1990-10-03
Abstract: PURPOSE:To make responsiveness and stability compatible with each other by varying control duty of a flow quantity valve provided in a bypass passage in response to a time variation rate of rotational speed of an internal combus tion engine. CONSTITUTION:The upstream and downstream sides of a throttle valve 5 are communicated with each other through a bypass side passage 35 for idling, and a flow quantity control valve 36 is provided in the side passage 35. A time variation rate of rotational speed of an internal combustion engine 10 is calculated from input from a crank angle detector 27 by a control unit 1. The control quantity of the flow quantity control valve 36 is varied according to the result of comparison between the time variation rate of the rotational speed and a specified judging level. When decrease in the rotational speed is detected, since an intake air flow quantity is rapidly increased by a large control quantity, engine stall can be surely prevented. When the decrease in the rotational speed is suppressed, since an intake air flow is varied slowly after it is rapidly decreased, blowing by overcontrol can be prevented, and thereby responsiveness and stability can be made compatible with each other.
