Abstract: A method for automatically changing the speed of a dump truck for use as a construction vehicle which is capable of improving the fuel cost by utilizing the engine output effectively and efficiently, improving the durability of the power transmission system and giving the driver a comfortable ride. According to this automatic speed change method, a desired, optimum speed stage which meets the loading condition of the dump truck and/or the engine output condition can be selected by using controllers each having a built-in computer.

Abstract: A method of controlling speed changes in a hydraulically actuated type multiple-stage speed change gear, which renders it possible to prevent the occurrence of "shift hunting" without impairing the acceleration characteristics of the vehicle and also reduce the magnitude of shocks which occur at the time of speed changes even in case hydraulic clutches of small capacity are used. According to this method of controlling speed changes, a controller (30) is used to conduct speed changes when conditions for speed changes, i.e., upshift/downshift are satisfied, and in cases where a downshift is made after an upshift and an upshift is made after a downshift, speed changes are conducted after the lapse of a long speed change inhibiting time, and in other cases than the aforementioned, speed changes are conducted after the lapse of a short speed change inhibiting time.

Abstract: The improved process for producing a signature panel comprises the steps of forming on the writing surface of a panel substrate a printed graphic pattern that will change upon exposure to alcohols, organic solvents, bleaching agents and surfactants, and laminating the other surface of the panel substrate with a thermoplastic resin by extrusion or hot melt coating. According to this process, signature panels can be thermocompressed at comparatively low temperatures not only to roll mills of overprint cards using a polyvinyl chloride sheet as an oversheet base but also to card substrates such as PET sheets, metal sheets and glass sheets without causing any adverse effects on the graphic pattern printed on the writing surface of the panel which will change upon exposure to chemicals.

Abstract: An object of this invention consists in exactly specifically identifying the position where abnormality arises in a speed changing system installed on a construction machine or similar vehicle. Specifically, a microprocessor (29) determines whether or not clutches H and L and clutch R, 1st, 2nd, 3rd and 4th are brought in an engaged state in conformity with clutch pressure commands (C.sub.1 l to C.sub.7). In addition, the microprocessor (29) determines whether or not the clutches are selected and then brought in an engaged state in conformity with the clutch pressure commands and shafts (2a, 7a and 8a) located before and behind the clutches are rotated in conformity with speed reduction ratios corresponding to the selected clutches. Thereafter, the microprocessor (29) exactly specifically identifies based on the results derived from the aforementioned determinations the position where a failure arises in the speed changing system.

Abstract: A novel .beta.-amylase gene is provided. This gene is useful for production of a thermophilic .beta.-amylase obtained from Clostridium thermosulfurogenes on a large scale, especially from genetically engineered microorganisms introduced with this gene. B. subtilis was transformed with a plasmid pNK1 containing the above gene and the transformed B. subtilis cells produced .beta.-amylase having the same thermostability as that of .beta.-amylase obtained from C. thermosulfurogenes.

Abstract: Each ceramic fiber block is temporarily supported by a supporting member and bar combination previously secured to the furnace casing, before it is finally secured to the casing by another supporting member and bar combination. No separate means for holding the block temporarily is required. As ceramic fiber blocks and supporting members are alternately attached to the casing, it is possible to ensure intimate contact between every two adjoining blocks. The absence of any extra work for holding the blocks temporarily improves the efficiency of the block installation work.
