Title: Real image type variable power finder optical system
Inventor: ITO YOSHIAKI
IPC: G02B23/14
Filed: 1989-07-04
Abstract: PURPOSE:To make the overall lens length relatively short although the power variation rate is high and the power is high and to obtain high optical performance while various aberrations are compensated excellently with simple constitution by setting the constitution of an erector lens under specific conditions and using aspherical surfaces properly. CONSTITUTION:An objective 1 is moved and the erector lens 4 is also moved to re-form a 1st finder image, formed by the objective 1, on a secondary image formation surface, thus varying the power. This erector lens 4 has a 1st lens 41 having positive refracting power, a 2nd lens 42 having negative refracting power, and a 3rd lens 43 having positive refracting power in order from the object side and an inequality I holds, where Rn1 and Rn2 are the radii of curvature on the object and image-plane sides of the 2nd lens 42. Consequently, although the power variation rate and power are high, the overall lens length is relatively short and the optical system of the simple constitution which has various aberrations compensated excellently and high optical performance is obtained.

Title: Brake controlling system
Inventor: MATSUMOTO YUKIO
IPC: B60T13/72
Filed: 1983-09-20
Abstract: PURPOSE:To always obtain deceleration corresponding to brake input by comparing both outputs of a brake input detecting sensor and a deceleration detecting sensor and controlling a control valve so as to make a brake assisting force generating part generate force corresponding to difference between the said both outputs. CONSTITUTION:When braking, the stepping force on a brake pedal 1 and the degree of deceleration are detected by a sensor 6 and a sensor 7 respectively, and inputted in a relative operator 8a. The output of the relative operator 8a is inputted in a pulse oscillator 8b. When the relation between the stepping force and the degree of deceleration is in an ideal condition, the output of the oscillator 8b causes a control valve B to be in a condition as shown in the figure. Therefore, connection between chambers 18 and 19 in a brake assisting force generating part A is severed, without causing any change in assisting force. When the degree of deceleration is small with respect to the stepping force, the valve B operates so as to connect the chambers 18 and 19, and air in the chamber 19 flows into the chamber 18 to carry out correction so that brake-fluid pressure is increased. When the degree of deceleration is large with respect to the stepping force, the valve B connects the chamber 18 to a vacuum source, carrying out correction so that the brake-fluid pressure is reduced.

IPC: H01L33/00
Filed: 1986-07-25
Abstract: PURPOSE:To make larger the effective area of the opening part of a window as well as to lessen the effect of stress to the window material by a method wherein a rapid heating treatment is performed on a metallic component having the window to form a low-melting point glass layer on the neighboring region of the window and after the low-melting point glass layer is reheated, the window material is installed. CONSTITUTION:First, a low-melting point glass layer 13 is once fixed on the neighboring region of the window 11 of a metallic component. Then, the low- melting point glass layer 13 is reheated and a window material 14 is installed. Therefore, the outlow of the lowmelting point glass is prevented and the opening region of the window can be kept making large sufficiently. Moreover, as the low-melting point glass layer 13 is once fixed, a weight for fixing is dispensed with in the case of equipment of the window material 14, and at the same time, a masking material is also unnecessary. As a result, the manufacturing process can be made into a simple one.
