Title: Differential torque converter
Inventor: SAWAMURA AKIROU
IPC: F16H61/62
Filed: 1983-06-15
Abstract: PURPOSE:To increase the capacity of a torque converter in the area of use speed by engaging a planetary gear supported on a carrier in one body with a power a output shaft with a sun gear in one body with a turbine runner and an internal gear in one body with a pump runner. CONSTITUTION:On an output shaft 1 of a prime mover, a pump runner P and an internal gear 5 are fixed, while a planetary gear 13 supported on a carrier 7 in one body with a power output shaft 6 is engaged with a sun gear 12 in one body with a turbine runner T and the internal gear 5. Since the turbine runner T in one body with the sun gear 12 is driven fairly in a high speed in comparison with the power output shaft 6 in one body with the carrier 7, the torque shared by this turbine runner T is reduced. Consequently, this turbine runner T bears a large input torque to increase the capacity of a torque converter.

Title: Mask for x-ray exposure
Inventor: SUZUKI KATSUMI
IPC: H01L21/302
Filed: 1978-09-01
Abstract: PURPOSE: To heighten the accuracy of X-ray exposure as well as to enable joint use of optical and X-ray exposures by protruding a part of support beam of mask for X-ray exposure into the side of X-ray absorption layer pattern across the main plane of X-ray penetration layer and use it as a spacer.  
     CONSTITUTION: A part of support beam 1 being formed by removing a part of Si single crystal substrate with (100) face as a main plane, is protruded into the X-ray absorbing layer 3 side which forms a desired pattern wherein a spacer 4 is formed. Thickness of spacer 4 is made thicker than the X-ray absorbing layer 3. Because spacer 4 is a unitary body together with a reinforcement member 1, its mechanical accuracy in size is precise, and the spacing between the wafer can be maintained at high accuracy by only making the spacer 4 contact lightly with the wafer to be processed. By so doing, joint use of optical and X-ray exposures as well as the heightening of accuracy in X-ray exposure are made feasible.

Title: Rubber molded part of power cable end
Inventor: KITAGAWA HIDEKI
IPC: H02G15/02
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To bolster an electrically weak point of a rubber molded part for use in a power cable, without increasing the thickness of the overall rubber molded part. SOLUTION: This rubber molded part is for power cable ends comprising a body 1 formed of insulating rubber and an electric field relaxing layer 3 which is placed on the inner circumference of the body 1. When the rubber molded part is attached to a cable end, the portion of the insulating rubber located in a position corresponding to the end of the cable shielding layer of the rubber molded part is made locally thick to form a tapered portion 4. Thus only the electrically weak point is thickened and thereby bolstered, and furthermore the body except for the tapered portion remains thin, therefore cable inserting operation is not interfered with.
