Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To enhance reliability of airtight sealing of a sealing body composing the joint of any one of the baser or cap of the facing surface and a nearby side face thereby preventing the development of crack. SOLUTION: In the semiconductor device, a semiconductor cap is mounted on a base 2 of a sealing body by face bonding system where the element forming face of the semiconductor cap faces the mounting face of the base 2 and then the base 2 and the cap are welded through a solder 5 to form the sealing body. Since the width at the joint 4c of the cap is set wider than the width at the joint 2c of the base 2, the joint 4c of the cap 4 can be composed of the facing surface 41c and a nearby side face 42c. Consequently, the development of crack can be prevented and airtight sealing performance can be enhanced. Consequently, circuit performance can be prevented from lowering and generation of malfunction due to short circuit of wiring, and the like, can be prevented.

IPC: A61K36/899
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To prepare a synthesis suppressant for a protein belonging to the HSP27 family comprising a malt extract. SOLUTION: This synthesis suppressant comprises 0.01-99wt.% malt extract as an active ingredient and has suppressing activities against the synthesis of a protein, belonging to the heat shock protein family (HSP27 family) and having 16-40 kDa molecular weight. Autoimmune diseases such as multiple sclerosis concerned with the onset of cancers in which the protein belonging to the HSP27 family is related to the malignant alteration thereof or reduction in hyperthermic effects can effectively be treated by administering the malt extract. Medicine resistance can be suppressed and chemotherapeutic effects can be enhanced by suppressing the expression of the protein belonging to the HSP27 family.  The malt extract is obtained by saccharifying malts, filtering the resultant saccharified malts, extracting the prepared filtration residue of the saccharified malts with water or a hydrophilic solvent or a mixture solution thereof and removing a fraction of a low-molecular compound having <10000 molecular weight. The daily dose for an adult is 1mg to 10g expressed in terms of the malt extract.

Title: Motorcycle
Inventor: HORIIKE TATSU
IPC: B62K11/00
Filed: 1988-05-10
Abstract: PURPOSE:To make the manual steering amount of a rear wheel larger through the small banking angle of a front frame by forward risingly swinging a connecting shaft between the front frame and a main frame to enlarge its attaching angle. CONSTITUTION:When a connecting shaft 9 is swung to make its axis have an angle of theta2, the intersection point P1 of an axis C-C is pushed up to P2' on the same shaft, and when a front wheel 3 is banked, the intersection point P1 moves to change into an intersection point P2 on an axis C'-C' tilted at the banking angle of thetab. In this case, a perpendicular drawn from the intersection point P2 is projected to an intersection point P2'' on the outside of an intersection point P1'', and an angle FRP2'' in a horizontal face therefore becomes the manual steering angle Rtheta2 of a rear wheel. Thus, when the connecting shaft 9 is forward risingly swung, the manual steering angle of the rear wheel turns into the state of Rtheta1<Rtheta2 in spite of the same banking angle of thetab to steer the rear wheel 7 at an angle larger than an usual one in a turning direction. Thus, the attaching angle theta1 of the connecting shaft 9 enlarges with the deceleration of running speed or increase in centrifugal force to increase the manual steering amount of the rear wheel 7 for improving cornering performance.

Abstract: PROBLEM TO BE SOLVED: To prevent damage in a core drill by arranging a frictional clutch, which slips when a feed motor is overloaded, in a mechanism transmitting power from the feed motor to a pinion. SOLUTION: When electric current is let flow into a coil so as to excite an electromagnet 35, a friction member 33 and a friction plate 36 are attracted, and power of a feed motor is transmitted to a shaft 37 via a worm gear device 23, a solenoid clutch 24, and a reduction gear 25, so that a pinion is driven rotationally. In this way, the pinion is moved along a rack, and feeding is carried out. During cutting, when an edge point of a core pit collides against a reinforcement or against a stopper arranged in the rack and a feeding load is increased, the friction member 33 and the friction plate 36 slip, and as a result, application of an abnormal load to the feed motor can be prevented.
