Pharmaceutical composition which comprises an insulin sensitivity enhancer in combination with other antidiabetics differing from the enhancer in the mechanism of action, which shows a potent depressive effect on diabetic hyperglycemia and is useful for prophylaxis and treatment of diabetes.

A method for manufacturing an ink jet head comprises a first step of arranging on a substrate a passage molding material to form ink paths conductively connected to discharge ports for discharging ink, a second step of arranging on the substrate an edge portion molding material in the vicinity of the passage molding material, a third step of arranging on the substrate a wall formation material to ...

Bleaching compositions are provided that comprise two nitrile groups where each nitrile is bonded to a quaternary nitrogen through a methylene unit. The quaternary nitrogens are part of a saturated ring. This saturated ring contains from two to eight atoms in addition to the quaternary nitrogen. A source of active oxygen will react with the nitriles for bleaching applications.

There are provided: a check valve (cb1) for detecting pressure at the outlet side of a pressure compensator (VB1); a maximum load pressure detecting pipeline (SL1) for selecting a higher pressure out of a pressure detected by said check valve (cb1) and a load pressure of an actuator belonging to a hydraulic pump (P1), to thereby supply it as a signal pressure; a check valve (cb2) for detecting a p...

Inching valves for providing controlled slow movement of a vehicle normally have a valve mechanism therein to control the pressure level of the fluid being directed to the driving clutch of the vehicle. Upon release of the pedal, a sudden jerk of the vehicle may occur. The modulating inching valve of the subject arrangement provides a housing having a valving mechanism slidably disposed therein an...

A two-dimensional sensor is described including a substrate having a Si layer, a SiO2 layer and a Si3N4 layer. On the surface of the Si back side, a thin film is formed by vapor deposition for making an effect electrode. On the surface of the Si3N4 front side, a fence is attached for containing a sample cell, culture medium and a reference electrode. This sensor is placed in an incubator and a bia...

In a DRAM which includes a memory cell consisting of one MOS transistor and one stacked capacitor, the node electrode of the capacitor is constituted of a stacked layer formed by alternately stacking a first conductor film and a second conductor film. As the first conductor film use is made of, for example, an n-type polycrystalline silicon film, and as the second conductor film use is made of, fo...

Petrochemicals (hydrocarbon derivatives) are produced by the vapour phase partial oxidation reaction of a hydrocarbon with air, if desired, enriched in oxygen, in the presence of a suitable catalyst. The petrochemical product is removed from the product gas stream, and part or all of the remaining gas stream is passed through a bed of hydrophobic adsorbent, which adsorbs mainly the unreacted hydro...
