Title: Active matrix display
Inventor: YAMAZAKI SHUNPEI
IPC: H01L21/20
Filed: 1995-01-28
Abstract: PURPOSE: To reduce the leak current upon turning a switching element off by connecting more than two TFTs in series with a single pixel electrode and controlling a TFT, except those at the opposite ends, through a gate signal line independent from a row select signal line. CONSTITUTION: When the potential on a row select signal line makes a transition to a negative level, TFTs 103, 104 are turned off. Since the potential on a gate signal line 107 is positive, a TFT 105 is turned on. The TFT mainly functions as a capacitor and the source-drain potential of the TFT 105 is equal to that of a pixel cell 106. When the potential on the gate signal line 107 makes a transition to a negative level, capacitance of the TFT 105 decreases abruptly. Consequently, the source-drain voltage of the TFT 105 is increased in order to hold the charges stored in the TFT 105. With such arrangement, potential drop is controlled and the off-current can be reduced.

Title: Inhibitor for decomposition of calcitonin
Inventor: HORI RIYOUHEI
IPC: A61K38/23
Filed: 1982-02-26
Abstract: PURPOSE:To titled inhibitor, containing a specific peptide as an active constituent, and capable of acting effectively in the injection site by adding to a pharmaceutical for injection. CONSTITUTION:An inhibitor for the decomposition of calcitonin containing a peptide, e.g. calcitonin fragment (11-32), having a peptide chain at the 11-12, 18-19 or 24-25 positions in the fragment having the same amino acid sequence as in the calcitonin obtained easily in synthesizing the calcitonin, e.g. ''Elcitonin '' derived from a rabbit or natural clacitonin derived from a salmon or pig, as an active constituent. The calcitonin is a peptide hormone consisting of 32 amino acids having the activity of reducing the blood serumal calcium. The use of the inhibitor in an amount of 5 times or more, preferably 10 times or more, based on the calcitonin inhibits the decomposition of the calcitonin well in the injection site. Thus, the resultant inhibitor is used as an additive in a pharmaceutical for injecting the calcitonin.

Title: Printing device
Inventor: WATANABE HIROYUKI
IPC: B41J2/045
Filed: 1989-02-10
Abstract: PURPOSE:To remove anxiety for clogging a nozzle by a method wherein an ink drop discharged from an ink discharging port is accelerated with a gas current containing water vapour in a printing device which records by discharging the ink drop. CONSTITUTION:Water vapour generated with a water vapour generator 104 is sent to a head 101 through a water vapour feed passage, and is always jetted from a water vapour discharge port 106. An ink discharge port is established in opposition to the water vapour discharge port, and ink is discharged from this ink discharge port 107 by vibration of a piezo-electric element 110 to be fragmented into ink drops. They are accelerated by a water vapour gas current jetted always from the water vapour discharge port and fly to recording paper. If only the ink drop is generated, ink discharge with the piezo-electric element is enough, and is satisfied by less force by being compared with the force in the case where the ink drop is transported to a surface of the paper only by the force of the piezo-electric element. Humidity in the water vapour chamber 108 where water vapour flows is almost 100%, and both drying of ink and clogging of a nozzle are removed.

Title: Manufacture of foamed decorative sheet
Inventor: MATSUO HIROSHI
IPC: B44C1/20
Filed: 1986-02-17
Abstract: PURPOSE:To manufacture a foamed decorative sheet full of cubic effect by a method wherein the lateral expansion of the portion, which is put on a base material and at the same time contacts with a first layer, of a second layer is suppressed during the foaming of the first layer so a to allow to increase the vertical expansion of the second layer, on which the first layer is put, by the extent in proportion to the extent of the suppressed lateral expansion. CONSTITUTION:The mean polymerization degree of polyvinyl chloride (PVC) paste resin employed as a plastisol layer or second layer is made to be 1,200-2,000 so as to heighten its melt viscosity in order to suppress the lateral expansion of the portion, which is put on a base material and at the same time contacts with a first layer, of the second layer during the foaming of the first layer and consequently to allow to increase the vertical expansion of the second layer, on which the first layer is put, by the extent is proportion to the extent of the suppressed lateral expansion. In the means polymerization degree of the PVC paste resin is below 1,200, its melt viscosity is low, while if its mean polymerization degree exceeds 2,000, its melt viscosity is too high and its poor foaming property results. When the width of the design or the diameter of the point design is 10mm or less under the condition that the interval between the designs formed in a pattern at the fist layer is 0.4mm or more, the remarkably effective result is obtained. The uprightness of the edge position corresponding to the rising position of the design is surely established and accordingly a foamed decorative sheet full of cubic effect can be obtained.
