Title: Inductive coupling plasma/mass spectrometer
Inventor: SAKATA KENICHI
IPC: H01J49/10
Filed: 1986-01-31
Abstract: PURPOSE:To make it possible to obtain an accurate analysis value by a mass spectrometer, by generating a magnetic field around the tip of a skimmer, and making the electrons ionized in the plasma exercise a spiral movement to get a longer travel distance. CONSTITUTION:When a plasma 6 is drawn out in a nozzle 4, electrons ionized in the plasma are given a spiral movement at the top end of a skimmer 5 by the action of a magnetic field. Therefore, the travelling distance is extended at the top end of the skimmer 5, the probability of striking of the plasma to the skimmer 5 is actually increased intensively. Consequently, ionization in the plasma is increased, the discharge current between the plasma and the skimmer 5 is increased, and the discharge voltage is decreased finally. For such a reason, the discharge voltage in the nozzle 4 is reduced, and as a result, the ion mass can be detected accurately by a tetrode mass spectrometer.

Title: Enclosed lead storage battery
Inventor: YOSHIDA TAKAMASA
IPC: H01M10/34
Filed: 1985-02-04
Abstract: PURPOSE:To aim at improving weight efficiency and life performance by composing a battery in such a way that a negative electrode at least out of both electrodes, positive electrode and negative electrode, has two plates with an electrolyte holding layer positioned between the two plates. CONSTITUTION:For instance, a negative electrode alone is composed of two negative electrode plates and an electrolyte holding layer 4a positioned between the two plates. An electrolyte holding layer 3 positioned in a gap between a positive electrode and a negative electrode, uses generally glass fiber mats which are mainly made of glass fibers with a diameter of less than 1mu. However, as for a retainer type of enclosed battery, it is desirable that the size of glass fibers involved is as big as the one used in the electrolyte holding layer 4a of each electrode, and as for a gel type (of enclosed battery), glass fiber mats made of glass fibers with bigger diameter can also be used for an electrolyte holding layer 4a of a negative electrode. In this way, both weight efficiency and life of an enclosed type of lead battery, can be improved substantially.

Abstract: PROBLEM TO BE SOLVED: To provide high compressibility without image quality decline from the time of simple compression by resolving source color images into three image components for respective pixels and compressing constituting component images for the respective components respectively by different compressibility. SOLUTION: The component images are obtained by component-resolving the source image into the three primary colors of an additive color process, red, green and blue, a spectrum is obtained by performing two-dimensional Fourier transformation for the respective component images and how much spectrum intensity is present in a high frequency component is calculated. Further, the diopter coefficient of the eye of a person to a light wavelength near the center of the respective colors is obtained, it is multiplied with the spectrum intensity and the complication of the image considering the sensitiveness of the eye of the person is obtained. Then, the image components of red and blue are less complicated than green and degradation at the time of being returned to the source image is small even at the time of adopting the large compressibility for the component images of red and blue.  Thus, information is compressed without accompanying the degradation of image quality based on high frequency component characteristics and the vision characteristics of the person, a storage capacity is made small and transmission is completed in a short time.

IPC: F16H9/00
Filed: 1990-01-30
Abstract: PURPOSE:To improve travelling performance, pump efficiency, belt durability and so on by controlling the extent of secondary pressure in a reverse range so as to nearly accord with the required brake pressure of a locking means conformed with engine torque or the like. CONSTITUTION:Secondary pressure by shift operation of an R range is fed to a reverse brake 18 for a forward-backward selector 4 and a gear element is locked by large torque capacity, through which reversed power is inputted into a continuously variable transmission 5, thus backward traveling takes place. At this time, the extent of required brake pressure is determined so as to accord the brake capacity of this reverse brake 18 with engine torque or the like and the secondary pressure is controlled, whereby power transmission comes to be done without entailing any belt slip in the continuously variable transmission 5 in which belt clamp force in the case of the same secondary pressure is set to be larger than that of the reverse brake 18 in consequence. Thus the secondary pressure is made controllable to a low level.
