Title: Memory initializing system
Inventor: NAKAJIMA HIROMASA
IPC: G06F12/16
Filed: 1988-07-06
Abstract: PURPOSE:To read out saved information before and after reset interrupt by checking the normalcy of parity bits of all areas of a RAM at the time of system reset interrupt and initializing the memory in accordance with the check result. CONSTITUTION:When a trouble detecting circuit 51 detects trouble during the input/output operation execution, trouble information is saved in a save area 9 of a RAM 2 and the processor operation is stopped. When the RAM 2 will be initialized at the time of system reset, all areas of the RAM 2 are first vacantly read. If a processor 1 accepts a parity error interrupt during this vacant read, a general area 8 and the save area of the RAM 2 are cleared throughout. If the parity error interrupt does not occur, only the general area 8 is cleared. The normal operation is restored after the end of initialization, and trouble information saved in the save area 9 is outputted to an input/output device 6.

Title: Facsimile equipment and image forming device
Inventor: TAKAHASHI MASAO
IPC: H04N1/387
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To print out a picked-up image without making an image read section complicated by converting an image photographed by a digital still camera into a signal of a form processed by the image read section of the facsimile equipment. SOLUTION: A video decoder 6 extracts a luminance signal from a video signal outputted from a digital still camera 4. A scan converter 8 writes A/D- converted luminance signal data to a DRAM 8 and reads the luminance signal data from the DRAM 8 synchronously with an image read clock of an image read circuit 12. In the case that a D/A converter 10 converts the digital luminance signal data unto analog data, the level of analog data matches the level of an analog image signal outputted from a CCD 13. Thus, the image read circuit 12 processes the analog image signal of the photographed image from the D/A converter 10 the same as the analog image signal outputted from the CCD 13.

IPC: H01M10/12
Filed: 1985-07-29
Abstract: PURPOSE:To lengthen the life of a battery, by providing a space under a positive and a negative electrode plates to allow the positive electrode plate to elongate downward to prevent the projections of the positive and the negative electrode plates from short-circuiting to a strap. CONSTITUTION:A nonwoven or woven fabric of fiberglass or the like is used as a separator 1 and interposed between a positive electrode plate 2 and a negative electrode plate to prevent these plates from short-circuiting to each other due to contact.

IPC: B28B7/00
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of concrete for joining a floor board and the falling of concrete by forming a recessed cotter opened only to the header surface of the PC floor board to the header surface. SOLUTION: A large number of recessed cotters 4 opened only to surfaces 1a-1d through regular intervals L1 in the longitudinal directions of the header surfaces 1a-1d of the PC floor board 1 are formed. Each floor board 1 is arranged as openings are formed among each opposed header surface 1a-1d while the parts of the floor boards are bridged on PC beams or PC wall boards, and templates are applied onto undersides in the openings of sections, in which there is no receiving surface, in the PC beams, the PC wall boards, etc., at the time of the execution of works. Concrete is placed into the openings and cured, and the templates are removed.  Accordingly, the gravity-drop of concrete can be prevented even when concrete at places, where there is no receiving surface, is cured and shrunk and is peeled from joint surfaces because concrete filled into the cotters and the openings is unified, and earthquake resistance can be improved because the cotters mutually constrain displacement in the vertical direction and the horizontal direction of the joined floor boards.

IPC: G09G3/36
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of the gradation drive circuit of a liquid crystal display which executes multi-valued gradation. SOLUTION: Gradation voltage setting sections 53, 54 form 512 pieces of positive and negative gradation potentials +V1 to +V256, -V1 to -V256 indicating the gradation data of, for example, 8 bits. The respective gradation potentials +V1 to +V256, -V1 to -V256 are divided in blocks by gradation potential block selection sections 55, 56 and are sequentially applied in time division to bus lines L1 to L32. As a result, the number of the bus lines L1 to L32 for supplying the gradation potentials to the gradation drive circuit per dot of the liquid crystal display are drastically decreased. The bus lines L1 to L32 for supplying the gradation potentials based on the gradation data are selected by a gradation voltage selection section 57 and the gradation potentials are applied to liquid crystal display elements via a sample-hold circuit 60 and an output circuit 70.

Title: Draft device for foam column
Inventor: HAGINO HIROSHI
IPC: C12M1/08
Filed: 1979-12-25
Abstract: PURPOSE: To suppress the occurrence of foams, by equipping a foam column with a draft device consisting of plural boards.  
     CONSTITUTION: When the air introducing inlet 3 is furnished at the bottom of the outer periphery of the draft device 2 consisting of many superimposed boards in the foam column 1 and air is introduced, the upward flow of liquid takes place on the outer periphery of the column, and the downward flow happens in the inside of the device 2. When the liquid flows partly from the gap of the boards into the inside of the device 2, the liquid is provided with a turning force by the faces of the boards and s swivel flow is produced in the inner side of the device 2. While the liquid level of water becomes higher by centrifugal force, etc. as the distance from the wall of the column l lessens on the surface of the liquid in the column l, and a vortex is formed on the whole. With the formation of the vortes, a flow in the direction of the center at the bottom of the boards is suppressed, and a sucking flow in the direction of the center on the surface of the liquid is promoted. Therefore, a downward sucking force at the center becomes very strong, and foams are swallowed up in the sucking flow to bring about improved defoaming effect.
