Abstract: PURPOSE:To enhance the mechanical strength, packing bulk density and ability to adsorb nitrogen of the titled adsorbent for air separation by forming said adsorbent with a composition consisting of a Ca-X type zeolite and a Ca-A type one. CONSTITUTION:A mixture consisting of Na-X zeolite powder, Na-A zeolite powder and inorg. binder is molded. This molded product is brought into contact with an aq. soln. of Ca salt to carry out an ion exchange, then dried and calcined to form said adsorbent. The higher the rate of Na-A/Na-X becomes, the lower the amt. of adsorbed nitrogen becomes and the higher the packing bulk density becomes. The treatment of activation caused by calcination is carried out enough by heating the blowing air passed simply through the zeolite layer at about 200-450 deg.C at about 5m/min flow rate for about 2hr.

Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To set magnetic spacing to be small while maintaining the reducing effect of an absorbing force by providing a variable shape projection having a projecting shape formed during the non-rotation of a magnetic disk and eliminated during the rotation of the same. SOLUTION: While a magnetic disk is operated, a magnetic head slider 1 floats on a rotating magnetic disk 7, a positive pressure larger than an atmospheric pressure is generated in a positive pressure rail part 2, and a negative pressure smaller than an atmospheric pressure is generated in a negative pressure groove part 3. Designing is made such that a pressure equal to 1.5 mb or higher is generated in the positive pressure part, and a variable shape projection 4 is provided in the area of the positive pressure rail part 2 of 1.5 mb or higher. Thus, a force is applied to a disk by a pressure higher than an internal pressure, a projecting shape is changed to be a recessed shape and, even if magnetic spacing is set small between a read/write element and the magnetic disk, the projection is prevented from being brought into contact with the magnetic disk 7, and low floating is realized while the reducing effect of an absorbing force is maintained.

Title: Semiconductor memory device
Inventor: DOSAKA KATSUMI
IPC: G11C29/00
Filed: 1985-12-06
Abstract: PURPOSE:To prevent access to a semiconductor storage device having a redundancy memory cell from being delayed by controlling gates and a switching element with the outputs of a redundancy decoder and a decoder and allowing or inhibiting the output of a clock. CONSTITUTION:When an address corresponding to a defective memory cell is inputted, selection and nonselection outputs of the redundancy decoder 1 and decoder 4 are H and L respectively. Consequently, switching transistors (TR) 3 and 5 turn on and off respectively and a clock phiA is outputted from the TR 3 to a redundancy bit line or word line and outputted to neither a bit line nor a word line. At the same time, when an AND gate 6 is opened and a clock phi2 goes up to H according to a clock phi1, a gate 7 is closed with the inverted clock phi2 and the clock phi1 is not supplied to the TR5. When the decoders 1 and 4 are selected and unselected, the clock phi2 goes down to L regardless of the clock phi1, the gate 7 is opened and the clock phiA is outputted through the TR 5 immediately, thereby preventing access from being delayed.

Abstract: PURPOSE:To read a transmission-type original DT without the need of an enlargement projection device with large constitution and to simplify the read work of the transmission-type original. CONSTITUTION:The transmission-type original DT such as a 35mm film is carried by a film carrier 50.

The transmission-type original DT is illuminated by light generated from a light source 35, is dispersed in a white original 60 and is guided by reflecting mirrors 36, 37 and 38. Thus, a picture carried by the transmission-type original DT is made incident on the light-receiving surface of an image sensor 40 through a lens 39. The film carrier 50 is vertically moved along an arrow 55. Thus, the area of the picture which is made incident on the light-receiving surface of the image sensor 40 changes. Consequently, the transmission-type original DT by the read object area of the image sensor 40 is scanned.
