Title: Production of magneto-optical recording medium capable of overwriting
Inventor: MIYATA KAZUTOMO
IPC: G11B11/105
Filed: 1993-06-15
Abstract: PURPOSE:To prevent the deterioration of a recorded signal due to repeated writing and to improve durability by using a target composed of alternately arranged heavy rare earth metal regions and transition metal regions and moving a magnetron magnet in the transverse direction of the regions at the time of sputtering. CONSTITUTION:A discoid target 1 is composed of alternately arranged sectorial heavy rare earth metal regions A and sectorial transition metal regions B. The sizes of the regions A, B depend on a recording medium to be formed. A magnet 2 for generating magnetron is moved in the circumferential direction of the target 1 and a substrate 3 disposed near the target 1 in a sputtering device is subjected to sputtering. The substrate can freely be moved through the sputtering spaces while keeping a vacuum state by a load lock system and a large number of recording media are continuously produced by moving a substrate every time sputtering is completed.

Title: Sheet separating plate for sheet feeder
Inventor: FUJIMOTO SAKAE
IPC: B65H3/68
Filed: 1978-11-21
Abstract: PURPOSE: To enable smooth separation/feeding of sheet, by forming the upstream side of sheet separating board contacting with sheet separating roller with sheet guide member having low friction factor while the down stream side with sheet separation board having high friction factor.  
     CONSTITUTION: Upstream side of sheet separation board contacting with sheet separating roller is formed of sheet guide member 6A having low friction factor while the downstream side is formed with sheet separation board 6B having high friction factor. Consequently even if the leading end of sheet 3 is contacted against the sheet separation board 6 under such state as slightly bending downward because of the self-weight of sheet, curl, etc., the leading end of sheet 3 is guided smoothly by means of smooth sheet guide member 6A, while when a plurality of sheets are guided lower sheet is blocked by sheet separation member 6B to feed only uppermost sheet. Consequently smooth separation/feeding of sheet is achieved.

Filed: 1978-11-20
Abstract: PURPOSE:To simplify the refractory working of a low temperature liquefied gas storage tank by mounting a reinforcing member for the roof portion of the tank on the back surface of a refractory material mounting surface. CONSTITUTION:A refractory material 3 is extended over the upper end of the inner surface concrete wall 1 of a low temperature liquefied gas storage tank to the peripheral wall extended from the inner surface of the concrete wall and to the inside of the roof continued thereto, where the reinforcing member 6 of the roof plate 5 is mounted on the upper surface of the roof, that is, on the back surface of the roof plate but not the refractory material working side. The member 6 is mounted on the inside of the roof palte 5 in the vinicity of the top of the crown portion not worked with the refractory material. Thus, the refractory working becomes ready. Since excessive extension such as reinforcing member is not provided, no refractory material is excessively necessary to thereby work a preferable finish.

Title: Vacuum suction casting method
Inventor: HASHIDA RIYOUZOU
IPC: B22D35/04
Filed: 1978-11-24
Abstract: PURPOSE: To prevent the production of defects of casting owing to slag inclusion by sucking up molten metal through the lance inserted into the molten metal in a melting furnace by making use of vaccum force and pouring the same into the mold.  
     CONSTITUTION: A vacuum tank 5 is beforehand kept at the degree of vacuum enough for molten metal 2 to ascend in a lance 3 by operating a vacuum pump 6. One end of the lance 3 is inserted into the molten metal 2 and the sprue 10 side being the other end is held tightly closed by an Al plate 9 and therefore when a valve 7 is opened, the molten metal 2 ascends in the lance 3 and falls in the direction of the mold 11. When this phenomenon begins to occur, even if no vacuum pressure is applied by closing the valve 7, the molten metal 2 melts the Al plate 9 and automatically passes in the lance 3 and is poured into the mold 11. This method obviates the inclusion of slag of the molten metal 2 surface and improves the soundeness of the casting.

Filed: 1980-10-15
Abstract: PURPOSE:To reduce noise and cross talk by converting a data sequence to be recorded into another data sequence through a pre-coder and then by restoring a reproduced signal to a data sequence through a post-coder having prescribed characteristics. CONSTITUTION:A data sequence to be recorded is converted into another data sequence through a pre-coder 14 and then a signal reproduced through a tape head system 15 is restored to a data sequence through a post-coder 17, etc. Characteristics Gpo(D) of the post-coder 17 are as shown by equationI. From equation II, the frequency characteristics of the post-coder 17 are found; when the frequency is zero and 1/2.1/Tb, the gain is reduced to zero and when 1/4.1/Tb, the gain is reduced to two. The post-coder 17, therefore, decreases in gain at a low-frequency and a high-frequency part, and noises of the high and low frequency parts are suppressed greatly. Thus, noises and cross talk are reduced.

Title: Driving method for serial injection type internal combustion engine during starting
Inventor: HEIDENFELDER HANS DIETER
IPC: F02D41/30
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To shorten a starting process by selecting driving by homogeneous mixture or stratified mixture according to temperature of an internal combustion engine, enabling the driving by the stratified mixture first after fuel pressure reaches a given threshold, and setting injection from relation between injection amount and injection finishing angle. SOLUTION: A control routine of a control device 21 changes over between a low pressure start by homogeneous mixture and a high pressure start by stratiform mixture depending on coolant temperature TKW of an internal combustion engine. Injection of the internal combustion engine in the high pressure start is enabled first after pressure PRail of a high pressure reservoir 28 exceeds a threshold of filing into a characteristic map of the control device 21. The injection is set with an injection finishing angle of injection amount in the high pressure start. Due to setting of this injection finishing angle, ignitable mixture exists on an ignition plug independently of ignition maintaining time. Advantageously, in the high pressure start, injection time is limited to most early possible injection start.
