Inventor: HATTORI SEIJI
IPC: H01L21/30
Filed: 1989-03-31
Abstract: PURPOSE:To generate forming beams of rectangle and other shapes, and precisely set form and size of the beam, by scanning a first forming aperture image on a second forming aperture by a forming deflection system, and obtaining the relation between the beam current which passes the second forming aperture or is reflected and forming deflection coordinates. CONSTITUTION:Between a first and a second forming apertures 41, 42, a forming deflection system 24 for beam forming is arranged; sizes and shapes of charged beams of rectangle and of the other forms are controlled, thereby drawing a desired pattern on a sample 11. In this charged beam pattern drawing method, when the reference position of the second forming aperture 42 for generating forming beams of rectangle and other shapes is obtained, a first forming aperture image 41a is scanned on the second forming aperture 42 by the forming deflection system 24. The relation between the beam current which passes the second forming aperture 42 or is reflected and forming deflection coordinates is obtained, and from said relation, the edge position of the second forming aperture 42 in the forming deflection coordinates is obtained. For example, the second forming aperture 42 is formed by connecting two rectangles so as to be mutually inclined at 45 deg..

Title: Output circuit for amplification solid-state image pickup device
Inventor: WATANABE YASUSHI
IPC: H04N5/374
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide an output circuit for an amplification solid-state image pickup device that can sufficiently ensure an operating margin with respect to fluctuation in a threshold voltage and a power supply voltage with a simple configuration and suppress fluctuation in current consumption and is stably operated at a low voltage. SOLUTION: A 1st source follower circuit in this output circuit consist of a 1st MOS transistor(TR) Q11 and a 2nd MOS load TR Q15 connected to the 1st MOS TR Q11 via a vertical signal line. A current mirror circuit consists of a 2nd MOS TR Q15, and a 3rd MOS TR Q21 of the same channel structure as that of the TR Q15 whose gate and drain are connected to a gate of the 2nd MOS TR Q15. A rain of the 3rd MOS TR Q21 is connected to a power supply via a fixed resistor R11. Since dispersion in a current flowing through the fixed resistor R11 and the 3rd MOS TR Q21 is small, dispersion in the current through the 2nd MOS load TR Q15 is decreased to ensure a wide operating margin.

Title: Aluminum-containing bearing alloy
Inventor: FUTAMURA KENICHIROU
IPC: C22C21/00
Filed: 1981-06-01
Abstract: PURPOSE: To contrive the improvement of fatigue strength and hardness of the Al-Sn bearing alloy and the maintenance of high temperature-hardness of the alloy, by adding a metal element having a specific solid solution limit to Al and a specific decomposition temperature of an intermetallic compound with Al to the alloy.  
     CONSTITUTION: An element having the maximum solid solution limit of a Al side- solid solution of 0.3atom% or more and having a decomposition temperature of an intermetallic compound with Al of the melting point of Al or higher is added to an Al alloy containing 30wt% or less Sn or Sn. As such a metal, Li, Ca, Cr, etc. are mentioned. The addition amount of the metal is determined considering the solid solution limit of it to Al and so that the appropriate deposition amount of its intermetallic compound with Al can be obtained by a heat treatment, but the addition amount need be more than the solid solution limit of it at a normal temperature. The metal element is completely solid solubilized in Al when the alloy is molten, and with the state maintained, the alloy is rapidly cooled. The above-mentioned pulverized intermetallic compound is deposited uniformly in the grain interface of Al by a heat treatment after the rapid cooling. The deposit is not resolubilized into Al and prevents the movement of the Al grain boundaries and also the coarsening of Sn grains.

Title: Bearing aluminum alloy and bearing unit
Inventor: NARA TAMOTSU
IPC: F16C33/12
Filed: 1978-07-11
Abstract: PURPOSE: To improve wear resistance of a bearing alloy independently of the material of a shaft, especially by addn. of Cr to a bearing alloy of Al-Sn type.  
     CONSTITUTION: As an alloy for bearing of an internal combusion engine is used an alloy comprising 3.5W35 % Sn, 1W7 % Cr, or further comprising ≤3 % Cu, or Mg, still comprising ≤9 % at least one member selected from the group consisting of Pb, Bi, In, the balance being Al. This bearing alloy is pressed to a backing steel plate to manufacture a bearing. Increase in Cr content increases hardness of the bearing alloy so as to prevent softening at high temp., causes no increase in size of Sn particles, and improves wear resistance independently of the material of the partner. Addn. of Cu, Mg simultaneously with Cr never decreases hardness, which is increased due to rolling, during annealing. Addn. of Cr, Pb, Bi, In refines Sn, improving adaptability and hardness. The alloy shows excellent performance when used for a shaft made of spheroidal graphite cast iron, the shaft which is used under particularly severe conditions.

Abstract: PROBLEM TO BE SOLVED: To purify the water in an inland sea-lake by providing an inflow port under the low-water level of the open sea, extending a downgrade inflow pipe close to the bottom of the lake from the inflow port and furnishing an outflow port having a check valve to the downstream end. SOLUTION: An inflow port 6 is provided under the low-water level of the open sea 1, a downgrade inflow pipe 5 is extended close to the bottom of an inland sea-lake 2 from the inflow port, and a check valve 8 is furnished to an outflow port 7. When the water level of the open sea 1 is raised above the water level in the lake 2 at high tide, the seawater of the open sea 1 flows in close to the bottom of the lake 2 through the inflow pipe 5, and the water level in the lake 2 becomes higher than the water level of the open sea 1. However, since the check valve 8 of the outflow port 7 is closed, the lake water does not pass through the inflow pipe 5 but flows out from the lake mouth, and the water in the lake 2 is purified.

Abstract: PURPOSE:To reduce noise at shading correction by increasing an incident storage luminous quantity to a photoelectric conversion means more than that in the case of reading a usual original when information to correct ununiformity of read information of the photoelectric conversion means is read. CONSTITUTION:A standard white board 211 are used to generate correction data of read data by R, G, B sensors of sensors 210-1 to 210-3. The standard white board 211 has almost uniform reflection characteristic for a visual light and has a white color. The standard white board 211 is used to correct output data of visual sensors 210-1 to 210-3. When relative dispersion correction data (shading correction data) such as sensitivity dispersion between elements of the sensors 210, lighting distribution and ununiformity of characteristic of lenses are sampled, the luminous quantity incident and stored onto the sensor 210 when the same original is read is relatively increased more than that when a usual original is read. Thus, the effect of noise is suppressed.

Filed: 1988-04-06
Abstract: PURPOSE:To improve recording density and transfer speed by forming the films of a recording layer which is subjected to recording or reproducing by light signals and a protective layer on a hollow cylindrical substrate surface consisting of a transparent material. CONSTITUTION:This recording medium 1 is formed by using the transparent material such as plastics formed to a cylindrical shape as the substrate 4 and forming the recording layer 5, the protective layer 6, and an over coat layer 7 successively on the outside surface thereof. Optical recording or reproducing is executed by using such cylindrical medium for optical recording and reproducing and causing the medium to be irradiated by light from the surface of the substrate 4 on the side where the recording layer 5 and the protective layer 6 are not formed. Since the recording medium is irradiated by the light through the substrate 4, the degradation in the reliability of recording by dust and dirt is obviated. Since the substrate 4 is cylindrical, the required area per information unit is equally set in the respective parts of the recording medium and the efficient recording is executed. The efficient recording with the high reliability, recording density and information transfer speed is thus executed.
