Title: Semiconductor storage device
Inventor: KAJITANI KAZUHIKO
IPC: G11C11/401
Filed: 1990-03-26
Abstract: PURPOSE:To prevent the occurrence of a multibit defect due to disconnection of column select signal lines by providing a means which selects common data lines different by select signal lines made non-common in the memory access operation. CONSTITUTION:Column select signals CSL1 to CSL512 are distributed to select signal lines CSDL1 to CSDL2048 branched to four halfway respectively and are supplied to corresponding column selecting circuits CSW1 to CSW2048. Selecting circuit SEL1 to SEL4 select common data lines different by memory blocks MB1 to MB4 which use select signal lines CSDL1 to CSDL2048 made non-common. Consequently, plural bits are prevented from being simultaneously defective even if one of four column select signal lines to which the same col umn select signal is transmitted is disconnected or goes to the half-disconnection state, and the reliability of a system dependent upon the error detecting and correcting function for a defect of one bit is secured.

Title: Magnetic recording medium
Inventor: SUZUKI TAKASHI
IPC: G11B5/64
Filed: 1983-04-26
Abstract: PURPOSE:To improve resistance to wear and corrosion by providing a synthetic resin protective layer which consists essentially of polyvinyl butyral resin and a moisture-curable type polyurethane resin and of which the weight ratio of the resins is a specific ratio value on a thin magnetic metallic layer. CONSTITUTION:A protective layer 5 consists essentially of a polyvinyl butyral resin and a moisture-curable type polyurethane resin and the weight ratio of both resins is 2:1-1:2. If the moisture-curable type polyurethane resin decreases off said range, the wear resistance of the protective layer is not enough and if the polyvinyl butyral resin decreases off said range, the corrosion preventive effect of the resulting protective layer is not enough. Such protective layer is formed by mixing the two resins at the prescribed weight ratio and coating the mixture by a known method. Since the moisture-curable type polyurethane resin is used, the curing progresses by absorbing the moisture in air if the protective layer is allowed to stand in the air and therefore there is the advantage of not requiring any special curing stage.

IPC: F15B20/00
Filed: 1991-03-13
Abstract: PURPOSE:To judge the nomarl condition and the abnormal condition where dust is caught by transmitting a fixed close signal by a switch when a torque signal is input after a valve close signal and changing-over the swtich when a torque signal is transmitted first to transmit an abnormal signal. CONSTITUTION:A valve closing signal 1 is an air signal transmitted by a valve closing detector when a sluice valve reaches this side of the totally closing position, and a torque signal 2 is a pneumatic pressure signal transmitted by a torque transmitter when the valve is closed and load torque reaches the preset value. In the normal case, when the valve closing signal 1 is applied to a pilot valve 3a and subsequently a torque signal 2 is applied to a supply port P of a single pilot vale 3, the torque signal 2 presses a diaphragm 6a of a pneumatic- to-electric transducer 6 from the output port B to light a blue lamp by a change- over switch. In the abnormal case, as the valve closing signal 1 is not applied to the single pilot valve 3, the torque signal 2 presses a diaphragm 61a of a pneumatic-to-electric transducer 61 from the output port A to light a red lamp by the change-over switch.

Inventor: NUKUSHINA MASANORI
IPC: D05B27/10
Filed: 1988-03-28
Abstract: PURPOSE:To maintain a uniform sewing pitch by causing a cloth feeding speed at the time of sewing and a speed at the time of delivery to be approximately equal by means of an automatic control means. CONSTITUTION:When a cloth delivery process is in, an air cylinder 12 is expanded, a cloth feeding roller 7 is made to slide-abut on the upper surface of a cloth to be sewn, and simultaneously, a cloth presser 1 to feed the cloth in a sewing direction C is lifted. Since the cloth feeding roller 7 is rotate-driven at a rotating speed synchronizing to a sewing machine motor 2 by means of a pulse motor 8, the cloth to be sewn is delivered in a discharging direction D inclined at approximately 15 deg. to the sewing direction C by means of the cloth feeding roller 7, and an operation is executed so as to remove the cloth from a needle location simultaneously with the sewing and to form an unoccupied ring string part. When the sewing in the number of stitches set in the cloth delivery process is completed, the unoccupied ring string part is cut in a string cutting process, and thereafter, the cloth to be sewn is discharged from the main sewing device.

IPC: A44C11/02
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To facilitate the connection and separation. SOLUTION: When a female metal fitting 1 is approached to a male metal fitting 2, a connecting body 20 is attracted to a bottom plate 6 by magnetic force, and the tip part 20a of the connecting part 20 is inserted into a cylindrical body 5. When the male fitting 2 is strongly pressed to insert the connecting body 20 to the cylindrical body 5, a projection 22 is engagingly locked by a locking part 8a to lay the female fitting 1 and the male fitting 2 into connected state. Since a lock lever 8 is rotated to release the engaging locking of the projection 22 by the locking part 8a when the stable part 8b side of the lock lever 8 is pressed, the male fitting 2 is pulled out against the attracting force between the bottom plate 6 and a magnet 21, and the female fitting 1 is separated from the male fitting 2.
