Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for sealing a semiconductor device, which does not generate hollows and through holes at the sealing part at the time of sealing a board and a case. SOLUTION: A board 21 whereupon a semiconductor element is mounted and a case 11 which has side walls are bonded at the periphery of the board 21 and the side walls of the case 11 by resin and the semiconductor element is airtightly sealed. At that time, a first resin, which has a prescribed softening start time or softening temperature, is previously arranged on the bonding plane of the side wall of the case 11, a second resin, which has a later softening start time or has a higher softening temperature than those of the first resin, is arranged on the inner wall of the side wall of the case 11, and the cover 11 whereupon the first and the second resin are arranged, is placed on the top of the board 21 to be heated. Then, the first and the second resins are melted and the board 21 and the case 11 are bonded.  At that time, even when a hollow or through hole 92 is formed on the bonding face, the second resin melts and flows to the bonding face to cover the hollow or through hole 92 after the first resin is cured.

Title: Radial tire with partial wear preventing fine grooves
Inventor: MASAOKA MASARU
IPC: B60C11/03
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent any early wear in a shoulder part from occurring by setting up two circumferential fine grooves in a tread position corresponding to a mean circumferential grounding length part at a grounding profile form at a time when the mass of maximum loading capacity is loaded upon filling up internal pressure corresponding to the maximum loading capacity in a radial tire inset in a standard applicable rim. SOLUTION: A tire is provided with four circumferential main grooves 1, having a mean grounding length part in a position of 45mm ranging from left to right in the cross direction from an equator line. Two fine grooves 2 of 12mm in depth are set up in a position of 45mm ranging from left to right in the cross direction from this equator line. An area of driving force being imposed on the tire and a branch line of this driving area are on the circumference where there is nearly means grounding length Lm, and if the driving force area and a braking force area are made to interfere with each other, abnormal abrasion is lible to occur there. Accordingly, if these fine grooves 2 are installed in the means grounding length part or the branch line of both driving force and braking force areas.  These two areas are parted from each other and since they are made so as not to interfere with each other, each of their absolute values becomes lessened in addition to that any abnormal abrasion is hard to occur, and thus abrasion resistance is improved.

Abstract: PROBLEM TO BE SOLVED: To make a highly reliable communication by holding an antenna which sends a radio wave of discrimination information to the outside always in one direction, and then preventing the information from being detected when a slip, etc., faces a disordered direction. SOLUTION: The tag 11 having a means for transmitting the discrimination information is constituted by shifting the gravity center position of a circuit board 37 having an antenna from the center, holds the circuit board 37 rotatably, and sets the antenna to the constant direction. Then the tag 11 consists of a package cover 31, a package substrate 32, a 1st holding part 33, a 2nd holding part 35, the circuit board 37, etc. Consequently, even if a slip, etc., faces a disordered direction, the antenna of the tag 11 always faces the fixed direction, so equipment which sends and receives information to and from this tag 11 can nearly be fixed at the same position. Therefore, the structure of the whole system is simplified and a highly reliable communication can be made.
