Inventor: HAMANAKA TOSHIYUKI
IPC: B28B1/26
Filed: 1988-10-12
Abstract: ( 57 ) Processes for producing hollow ceramic articles such as ceramic port liners are disclosed. Such ceramic articles are produced by using a water-absorbable mold (1) having water non-permeable faces (4) on an inner surface (3) of the mold at locations corresponding to valve holes. 
     The thickness of a ceramic layer deposited on the inner surface of the mold is controlled by measuring an amount of a lowered liquid surface level of the slurry near a slurry-pouring opening of the mold. 
     Open ends of a hollow ceramic article are formed by cutting corresponding closed ends after deposition of the slurry and firing. 
     A uniform thickness of a slurry deposited onto the inner surface of the mold can be attained by rotating the mold around an arbitrary rotary axis at a rotation speed of 1 to 60 rpm. 
     All ceramic material contained in the slurry fed inside the mold may be deposited on the inner surface of the mold while the mold is being rotated or swung.

Abstract: The suspension control apparatus includes a control unit 37 which is connected to receive the output signals from a transverse acceleration sensor 39, a vehicle-speed sensor 38 and a steering sensor 40 for calculating the rolling state of the vehicle due to a transverse acceleration and controlling the respective suspension units S based on the calculated rolling state of the vehicle so as to suppress rolling. The control unit determines the period of frequency of change or reversal of the direction of the detected transverse acceleration of the vehicle, and controls the suspension units so as to disable the roll-suppression control when the frequency of reversal exceeds a prescribed level. The control unit further performs the first roll-suppression control operation and stop subsequent roll-suppression control operations from the instant when the frequency of reversal of the direction of the transverse acceleration exceeds the prescribed level.

Abstract: A text-processing system in which the sound signal corresponding to a text is applied not only to a speech-recognition device (1) but also to a first further memory (15) for storage, start marks and end marks being allocated to the words detected by the speech-recognition device (1). These marks are related in time to the sound signals stored in the first further memory (15) and are stored in a second further memory (16). In this way a correlation is obtained between the sound signals stored in the first further memory and the individual words detected by the speech-recognition device. The detected words can be reproduced on a display device (13) thereby enabling the sound signal stored in the first further memory and corresponding to a specific detected word to be reproduced acoustically so as to verify the accuracy of a word detected by the speech-recognition device and to correct an erroneously detected word.

Abstract: This invention describes polymers which are obtained by copolymerization of 15-85 wt % N,N-dimethylacrylamide with about 15-85 % of a fluorinated monomer such as perfluoroalkyl-alkylene acrylate or -methacrylate with from 3 to 25 fluorine-atoms and optionally, 0-50 wt % other acrylates or methacrylates and 0-20 wt %, but not more than 5 mol % of a polyvinyl functional crosslinking agent. These polymers are machinable in the dry state and form clear hydrogels with about 25-75 wt % water content and which possess oxygen-permeabilities 3-7 times higher than conventional hydrogels of similar water content. In the absence of crosslinking, the novel polymers are plasticized by water, forming clear hydroplastics with 30-70 wt % water content. The crosslinked polymers are especially useful for fabricating contact lenses for extended wear by either cutting and polishing a xerogel button, or by spin casting or direct molding in bulk or in solution.

Abstract: An apparatus for attaching bottom stops (20) of a generally H-shaped cross section to a slide fastener chain (C). According to a preferred embodiment, a pair of stringer tapes (T₁, T₂) of one of successive spaced element-free space sections (S) are spread apart by spreading member. The top and bottom faces of the center base of the bottom stop (20) are clamped resiliently by clamping members (30, 40) until attaching of the bottom stop (20) to the fastener chain is finished and the clamping members (31, 41) move vertically for placing the bottom stop between the stringer tapes (T₁, T₂) of the space section (S). The spread pair of stringer tapes (T₁, T₂) are then drawn near to come toward each other by drawing member until the beaded edges (d₁, d₂) of the space section can be threaded respectively through spaces formed between the pair of gripping legs of the bottom stop. Then the fastener chain (C) is transported so that the bottom stop (20) is located to be contacted with the space section-side face of the terminal element of the row (E) of coupling elements. Finally, the gripping legs of the bottom stop (20) is caulked with a punch (1) and a die (4) for attaching the bottom stop (20) to the fastener chain (C). In the present invention, since clamping operation is carried out so as not to interfere with caulking operation, the bottom stop can be attached to the slide fastener chain surely and precisely.
