Title: Cylinder liner of reciprocating engine
Inventor: AKIZUKI YUKIO
IPC: F01M1/16
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the penetration of lubricating oil into a combustion chamber as well as to make this oil sufficiently feedable to a cylinder liner inner surface by making the lubricating oil scraped up by a piston ring flow out on the cylinder liner inner surface via an oil catcher groove and an on-off valve being driven by an electromagnet, and scraping off the oil and recovering it for reuse. SOLUTION: Lubricating oil 6 scraped up by a piston ring 4 is collected in a top land clearance 5 lying between a cylinder liner 1 and a top land 3a, and further scraped up and collected in an oil catcher groove 7. Next, this lubricating oil 6 is reached to a sheet valve 12 by way of an oil through hole 10, and it is dammed up hereat when this sheet valve 12 is closed. In succession, when an opening period of the sheet valve adjusted by a hydraulic timing setter 17, namely, a discharge period from a lubricating oil delivery port 21 is inputted into an electromagnet control unit 16, the sheet valve 12 is opened by current- carrying to an electromagnet 15, whereby the lubricating oil 6 in the top land clearance 5 is made to flow out on a cylinder liner inner surface 1a at the lower part, then it is scraped down into downward oil sump by the piston ring 4 and recovered for reuse.

Title: Crystal growth method
Inventor: SAKAMOTO KUNIHIRO
IPC: H01L29/04
Filed: 1990-10-18
Abstract: PURPOSE:To laminate fine line structures whose cycle is different by a method wherein a part near a plane (001) at an Si or Ge single-crystal substrate is kept in such a way that its temperature can be controlled, the growth operation of a crystal is interrupted by controlling the temperature and the crystal is grown by being separated into two monoatomic layers. CONSTITUTION:An Si substrate 100 is housed in a vacuum chamber; and it is kept at a required temperature by using a heater or a cooling device. When both orientations of the substrate are close to <001>, step edges are situated along <011> and two kinds of monoatomic-layer steps are produced. A monoatomic-layer step SA where atoms on the terrace on the step, unbonded hands and a step end are vertical and a step SB which is parallel to it are arranged. A temperature is controlled; the Ge monoatomic-layer step SB is used as a starting point; a 0.5 atomic layer is formed selectively; and the steps SA, SB are separated. When the growth interruption time is set sufficiently, the interval between the steps GA, SB is returned to an interval before the growth operation. The step SB is used again as a starting point; a selective growth operation is executed in the same manner; and the steps are separated. When the operation is repeated, it is possible to form the extremely fine line structure of Ge in which the diffusion and the adhesion rate of Ge are controlled and which uses the interval between the monoatomic-layer steps SA, SB of the Si substrate is used as a cycle.

Abstract: PURPOSE:To improve the tracking performance to a target by a method wherein a dome for the guiding device of a guided missile is provided with an optical wave seaker and an optical wave window, closed along the dome in an initial period and opened in accordance with a signal from the guiding device. CONSTITUTION:When a guided missile is far from a target, an optical wave window 2 is closed under a condition that the window is along the configuration of a radio wave dome 1 while the guided missile is guided to the target by a radio wave seaker 3. The radio wave dome 1 can be provided with good radio wave characteristics or a long detecting range and a low air resistance. When the guided missile has approached to the target and has arrived at a near distance capable of using an optical wave seaker 4, a command from the radio wave seaker 3 is transmitted to the optical wave window 2 whereby the same window 2 is opened. The optical wave seaker 4 is operated employing the optical wave window 2 having a high transmittance of optical wave or a large angle of incidence of the optical wave. In this case, cooling gas is ejected against the optical wave seaker 4 from a nozzle 7 to prevent the temperature rise of the optical wave window 2 and restrain the same window 2 from radiating infrared rays. The target tracking performance of the optical wave seaker 4 is improved and a high accuracy of guidance can be obtained.

Abstract: PURPOSE:To obtain a stable binarized output signal by enabling automatic operation without operator's adjustment, by automatically correcting the variation of a signal without receiving restriction from an apparatus or a subject. CONSTITUTION:From video signal input S1, the max. value corresponding to a copper foil level is detected by a detector 1 and the min. value corresponding to a base material level is detected by a detector 2 and the arbitrary intermediate value of the signals from both of them is set as one input of a comparator 4 through a dividing circuit 3 and compared with the signal S1 to be binarized. Further, a pattern detection part 5 detecting the presence of a copper foil pattern from the signal S1 is provided. Only when the output of the detection part 5 judged 'pattern presence', the max. and min. values are sampled and, when judged' pattern absence', the max. and min. values at that time are held and, next, binarization is performed on the basis of a definite threshold value until a pattern is obtained. By this method, even when the frequency of appearance of the copper foil pattern is low, the threshold value is stable and accurate binarization can be performed.
