Title: Intake/exhaust control device for engine
Inventor: HITOMI MITSUO
IPC: F02M25/07
Filed: 1989-12-25
Abstract: PURPOSE:To enable the maximum value of the amount of intake/exhaust overlap to be set to a larger value by setting the valve timing so that the crank angle from the opening of an intake valve to the top dead center in an idle condition is larger than the crank angle from the top dead center to the closing of an exhaust valve by at least a specific angle. CONSTITUTION:Even at the time of idle operation in which an intake control valve 7 is in a closed condition, since there is a clearance sufficient for passing the intake air required for the idle operation, intake air is allowed to flow in to attain approximately an atmospheric pressure. In other words, since the gas pressure in the inside of an intake port before an intake valve 3 is opened is approximately an atmospheric pressure, even if the intake valve 3 is early opened, already burnt gas does not flow into the inside of the intake port, and even if the opening timing of the intake valve 3 is advanced, the amount of remaining gas in the inside of the combustion chamber at the time of idling is not increased. In this case, since the crank angle from the opening of the intake valve 3 to the top dead center in an idle condition is set to be greater than the crank angle from the top dead center to the closing of an exhaust valve 4 by at least 10 degrees, the amount of intake/exhaust overlap at the time of idling can be increased.

Title: Suspension controller
Inventor: HIRAI TOSHIRO
IPC: B60G17/015
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To attain sufficient damping force even at the time of damping from a low speed by switching a limiting value which limits a target controlling position into a larger prescribed value than the limiting value at the time of a low speed for a prescribed time when the decelerating state of a vehicle body is detected or estimated, and a decelerating state detected value is estimated to be larger than a prescribed value. SOLUTION: A controller 4 inputs signals of vertical acceleration sensors 51FR-51RR, a vehicle speed sensor 52, and a brake switch 53, and controls step motors 41FL-41RR; that is, a target control position is calculated based on a sprung and unsprung speed calculating value, a limiting value is set based on a vehicle speed detected value, and the calculated target control position is limited by the limiting value. At this time, when a decelerating state of a vehicle body is detected and a decelerating state detected value is estimated to be larger than a prescribed value, the limiting value is switched into a larger prescribed value than the limiting value at the time of a low speed for a prescribed time. It is thus possible to provide sufficient damping force for respective damping force variable shock absorber 3FL-3RR.

Title: High insulation ceramic board and manufacture thereof
Inventor: TANDA KENJI
IPC: H05K1/03
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a high insulation crude ceramic board having excellent void occupation ratio and insulation breakdown strength by forming a green sheet having special crude density or more of a ceramic material having relatively low alumina purity by a roll compaction method, and baking it at a special temperature or lower. CONSTITUTION:Even if a ceramic material having relatively low alumina purity of 90-99wt.% Al2O3 content is used, voids are reduced thereby to provide excellent insulation. That is, the material is subjected to a roll compaction molding to form a green sheet having a density of 2.4g/cm<3>. Thus, the voids in the sheet are reduced. Its baking temperature can be 1600 deg.C or lower due to high density, and grain growth of its crystal is suppressed to reduce the voids. Therefore, obtained ceramic board has 8.5 or less of void occupying ratio in section of a thickness direction and 20kV/mm or more of insulation breakdown strength.

Abstract: PURPOSE:To adjust an optical axis quickly and well by searching a path of an electron beam passing an electro-optical system while scanning a preset x-y region and obtaining rough parameters for indicating the path. CONSTITUTION:A matching coil control circuit 26 generates a signal (ATX, ATY) for TILT and a signal (ASX, ASY) for SILT. A preset region is designated according to lengths of the X-axis and the y-axis by ASX, ASY. The region is scanned, a quantity of secondary electrons from a sample 18 is monitored, and the peak value of a corresponding electric signal S2 is detected by a peak- hold circuit 31. When a reference value is exceeded, a signal S4 is generated. Values of deflection signals ASX, ASY at this time are taken as x-y parameters to be used as initial values of matching and are transferred smoothly from coarse to fine adjustment. In the coarse processing part, a crossed image is shifted to the CRT center by ATX, ATY, symmetry of the image is unified by ASX, ASY to finish the matching scan. Accordingly, even an optical axis deviated to much extent can be matched quickly and well.
