Title: Wide-angle image forming lens
Inventor: FUJIOKA IWATATSU
IPC: G02B13/18
Filed: 1989-03-03
Abstract: PURPOSE:To obtain a lens which has excellent optical characteristics while reduced in the number of constitution elements by making both the convex surface of the front positive lens of a 2nd group which contacts object-side air and the concave surface of the 3rd group which contacts the object-side air aspherical. CONSTITUTION:The wide-angle image forming lens is constituted almost symmetrically of the small number of lens elements, i.e. a 1st group of a negative meniscus lens having its convex surface on the object side, the 2nd group consisting of the positive lens having the large-curvature convex surface on the object side and a following positive lens having its large-curvature surface on the image side, and the 3rd group of the negative meniscus lens which has its convex surface on the image side. Therefore, the spherical aberration and comatic aberration are removed by making the foremost surface of the 2nd group, where luminous flux is incident with the largest width, aspherical and the object-side concave surface of the 3rd group is made aspherical to remove the remaining comatic aberration, thereby improving the flatness of an image plane. Thus, the number of constitution elements is decreased and the excellent optical performance is obtained.

Title: Semiconductor memory device
Inventor: SAKURAI MIKIO
IPC: G11C29/00
Filed: 1990-03-01
Abstract: PURPOSE:To test a memory cell having a threshold defect in a short time by providing a potential switching means which sets bit lines to a level lower than the level of one data stored in the memory cell at the time of read from the memory cell in response to test mode detection of a test mode detecting circuit. CONSTITUTION:When a column address strobe signal CAS and a write enable input signal W are in the low level at the time of fall of a row address strobe signal RAS to the low level, a test mode detecting circuit 50 gives a test signal T to a switch circuit 30. Since bit lines are set to a level lower than the level of one data stored in a memory cell MC at the time of read from the memory cell MC in response to the test mode, electric charge is apt to leak if the memory cell has a threshold defect in the transfer gate. Thus, the memory cell having a threshold defect is tested in a short time.

Abstract: PURPOSE: To prevent the ink passage of a writing tool from plugging even when the writing tool is left alone after use, by improving the drying resistance of ink by adding 1,3-dimethyl-2-imidazolidinone to an aqueous ink comprising water and a water-soluble dye.  
     CONSTITUTION: To an aqueous ink containing about 0.1W30wt%, based on the total weight of ink, a water-soluble dye such as an acid dye, a direct dye or a basic dye, is added about 2W50wt%, based on the total weight of ink, and particularly, for inks for writing tools, about 5W40wt% of 1,3-dimethyl-2-imidazolidinone.  Thereby, the drying resistance of ink is markedly improved, and even when a capillary writing tool such as a writing tool having a fiber or felt pen point or a fountain  pen is left alone with its cap removed, the ink does not plug the passage of the pen  point and flows smoothly through the pen point.
