Title: Microscope reflecting objective
Inventor: KASHIMA SHINGO
IPC: G02B21/04
Filed: 1989-07-27
Abstract: PURPOSE:To obtain the reflecting objective which has its spherical aberration compensated excellently by using only spherical surfaces by arranging all of 1st -4th reflecting mirrors symmetrically about an axis, giving the 1st reflecting mirror a positive power and the 4th reflecting mirror a negative power, and making their surfaces all spherical. CONSTITUTION:The 1st reflecting mirror M1, 2nd reflecting mirror M2, 3rd reflecting mirror M3, and 4th reflecting mirror M4 are all arranged symmetri cally about the axis in the order of incidence of light from a sample. Then the 1st reflecting mirror M1 has a positive power, the 4th reflecting mirror M4 has a negative power, and the reflecting surfaces are all spherical. When the reflecting objective has two surfaces with power, the spherical aberration can not be compensated sufficiently by a spherical system. Three reflecting surfaces, however, are provided to compensate the spherical aberration almost completely even by the spherical system. When light is reflected three times, the object point and image point are formed on the same side, so the number of times of reflection is increased to four.

Title: Semiconductor device
Inventor: TETSUYA TOSHIO
IPC: H01L21/52
Filed: 1985-09-04
Abstract: PURPOSE:To inexpensively form a semiconductor device and to prevent its electric characteristics from being deteriorated by forming the second metal layer which mainly contains gold and the fifth metal layer which mainly contains tin and copper. CONSTITUTION:Since a tin-copper alloy (the fifth metal layer 16) is used as a brazing material, its cost becomes 1/10 or lower. A problem that a local battery is formed between tin, copper (the fifth metal layer 16) and nickel (the fourth metal layer 13) is eliminated to improve the quality. When the structure of a vanadium layer (the third metal layer 12), a nickel layer (the fourth metal layer 13) and a tin-copper alloy layer (the fifth metal layer 16) is formed, the copper of the tin-copper alloy layer is diffused in a silicon substrate to become an acceptor to deteriorate electric characteristics such as VBCF of an N-P-N transistor, but a gold-antimony alloy layer (the second metal layer 17) is formed, the antimony of the alloy layer is diffused in the substrate 1 to become a doner impurity to cancel the effect of the acceptor of the copper-the impurity to prevent the electric characteristics of the transistor from being deteriorated.

Title: Device for collecting predetermined amount of blood
Inventor: HIROTA ATSUSHI
IPC: A61M1/00
Filed: 1990-07-24
Abstract: PURPOSE:To collect blood at the optimal blood flow correspondingly to various blood vessels of different donors by dropping negative pressure within a vacuum chamber to an aimed low pressure level under the condition that the variation of collected blood the amount of which is measured by a collected blood amount measuring means is decreased, and then raising the negative pressure toward an aimed high pressure level, and repeating this pressure control until a predetermined amount of blood is collected. CONSTITUTION:A blood-collecting bag receiving pan 3, an oscillating mechanism 4 for the pan 3, and a collected blood amount measuring means 5 for measuring the amount of blood collected into a blood collecting bag are provided within a vacuum chamber 1. Negative pressure within the vacuum chamber is raised toward an aimed high pressure level and blood from a donor is collected into the blood collecting bag and also the amount of the blood collected is measured by the collected blood amount measuring means 5 and the variation of the measured amount of the blood is calculated. When the variation is decreased i.e. the flow of the blood to be collected is decreased as the wall of a blood vessel is sucked by the end of a blood collecting needle, the negative pressure within the vacuum chamber is dropped to an aimed low pressure level and then the blood vessel reverts to its initial state and a predetermined flow of blood to be collected is recovered. The negative pressure is raised again toward the aimed high pressure level and blood is collected from the maximum blood flow that varies with donors. The above process is repeated whereby a predetermined amount of blood is collected into the blood collecting bag.
