Title: Production of extra-thick tempered steel material
Inventor: UCHIDA KIYOSHI
IPC: C22C38/46
Filed: 1985-08-15

CONSTITUTION:The steel contg., by weight, 0.06-0.18% C, <=0.10% Si, <=1.00% Mn, 3.00-12.00% Ni, 0.40-3.00% Cr, 0.20%n2.00% Mo, <=0.010% P, 0.03-0.20% V, 0.005-0.040% Al and 0.0010-0.0150% N is produced. Such steel material is hardened at the temp. above the Ac3 transformation temp. After the hardened steel is subjected to the primary tempering treatment in a 550-680 deg.C range, the steel is subjected to the secondary tempering treatment. The extra-thick tempered steel plate having the high yield strength is obtd. without deteriorating the toughness by the above-mentioned method. The steel plate is free from low temp. temper embrittlement and the toughness value thereof at the wall thickness section is made homogenous.

Title: Trigger pulse generating circuit
Inventor: FUJISHIRO SUNAO
IPC: H03K3/03
Filed: 1984-08-29
Abstract: PURPOSE:To generate trigger pulses, each of which is composed of the (N)-th trigger pulse and (N+1)-th trigger pulse, at every fixed time, by changing the resistance values of a resistor for fixing a discharging time constant and another resistor for fixing a charging time constant by means of a variable resistor so that they can become opposite to each other. CONSTITUTION:When a point (a) is H, the electric charge charging a capacitor C1 is discharged to another point (b) through a variable resistor VR, resistor R3, and diode D2. On the other hand, when the point (a) is L, the capacitor is charged with electric charge from the point (b) through a diode D1 and resistor R2 and the variable resistor VR. Therefore, when the variable resistor VR is changed, time constants of the charging and discharging are changed and the duty is changed. However, when the variable resistor VR is adjusted, the cycle is fixed because the overall time constant is fixed since one side resistance value decreases when the other side resistance value increases. Therefore, trigger pulses, each of which is composed of the (N)-th trigger pulse and (N+1)-th trigger pulse, can be generated at every fixed time.

An astigmatic aberration for all dimensions is mainly corrected by the fourth groups 21-24, and the space generates the high- order coma aberration and a distortion aberration. A low-order distortion aberration is corrected by selecting optimum reflection force between the second groups 14 and 15 and the fourth groups 21-24. The color of an axial direction is balanced against the color aberration of a visual curvature and the colors in the lateral direction of the second groups 14 and 15 are balanced against the fourth groups 21-24. Thus, the size of an image can be reduced.

IPC: B60T13/68
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a forming method for an operation signal for operating a pressure medium supply pump in a brake system and the equipment therefor to avoid a delay in detection of capacity demand request, and a delay in response to gentle pressure reduction. SOLUTION: In an operating method for a pump 100 for supplying a pressure medium in a brake system and the equipment therefor, the formation of an operation signal for the pump 100, particularly, an input signal is a function for at least one condition. The formation of the input signal is the function of a pressure gradient value, particularly, that of pressure gradient from an accumulator 106. This allows compensation for disturbance, including a temperature influence on the pressure medium exerted as low pressure gradient. In observing high capacity demand request, namely, high pressure reduction, resulting in the presence of high pressure gradient, a value significantly lower than the lower limit threshold value is avoided.
