Abstract: PROBLEM TO BE SOLVED: To improve connection of an object to be contacted like a substrate and a bump on the IC chip side, and reduce imperfect connection, by forming the bump on a bonding pad formed on the outer surface of an IC chip, and arranging cavities inside the bump. SOLUTION: A bonding pad 11 is exposed from an aperture formed in a passivation 12 on the surface of an IC chip 10. A bump 15 having cavities 16 is formed on the bonding pad 11. In the case of face down mounting of the IC chip 10, biased mechanical stress generated by the deterioration of flatness between the substrate and the chip can be reduced in virtue of existence of the cavities 16. That is, when the bump 15 made of solder is compression-bonded by an excessive force, the bump 15 is crushed and buried in the cavities 16. By this cushioning structure, biased stress and load from the bump 15 can be relaxed.

Title: Signal processing circuit
Inventor: OOTA TSUNEAKI
IPC: G10L19/00
Filed: 1982-08-19
Abstract: PURPOSE:To suppress noise and to obtain good sound quality, by using an expander so as to decrease an output level when an input level is small. CONSTITUTION:An input terminal 22 is connected to an output of a transmission system 18 and an output terminal 29 is connected to a VCA19, respectively. The time constant is determined by an input resistor 23, an output resistor 28 and a capacitor 27. The inclination of the expanding characteristics is increased more as the input level is smaller from nearly -30dB, the ratio of expansion is increased and this characteristic depends on the value of a voltage V and the time constant. When the input level x1 to the compressor is as x1>-60dB, the relation of x1=x2 (expander output level) is obtained and the level is restored to the original level. With x1<-60dB, the relation of y2<y1 is obtained, the compander output is smaller than the input level and the noise is suppressed.

Title: Protective device of switch-type automatic transmission
Inventor: TAKEDA MASAHIRO
IPC: F16H61/16
Filed: 1983-08-06
Abstract: PURPOSE:To protect an automatic transmission from any damage resulting from improper operation of speed changing means caused by the driver's neglectful or careless behavior of shifting a gear range into an unexpected position during forward or reverse driving by providing a unique operating circuit between a car speed sensor and an electromagnetic means control circuit. CONSTITUTION:When a speed sensor 1 generates an output, an AND gate receives signals of H at both the input-side thereof and generates the signal of H at the output-side thereof. The pulse is then sent to a frequency-to-voltage converter 4-1 and it generates a voltage corresponding to the frequency namely, the car speed. If the voltage is over a threshold level of an inverter gate 13-2, namely, if the car speed is high, the gate 13-2 generates a signal of L at the output terminal thereof and the signal of L is applied to one of the input terminals of an AND gate 3-3. Because of the reason, even if reverse switch 7 is kept on, the output of the AND gate 3-3 is remained L so that a motor driving circuit 5 generates no output. A servo motor 6 will not be operated reversely.

Title: Elastic joint
Inventor: MIYAGAWA SHINJI
IPC: F16D3/62
Filed: 1990-05-31
Abstract: PURPOSE:To display required performance by weaving a weft, which constitutes a tape in a reinforced part of an elastic joint, crossed with a warp, folding back the weft in one side end of the warp in a reverse direction, and zigzag extending the weft in the lengthwise direction, while folding back the warp, to suppress it from spreading. CONSTITUTION:A reinforced part 3 of an elastic joint is formed by overlap- winding a tape 30 in a loop shape on the adjacent fellow first and second mounting tools 1, 2. Many warps 31 for constituting the tape 30 are extended in the lengthwise direction to parallelly run between the mounting tools 1, 2. A single weft 32, which constitutes the tape 30, is woven in a direction of crossing with the warp 31, folded back in one side end of the warp to form a fold back part 32a, woven in a zigzag shape in a reverse direction and extended in a direction of an arrow mark X. When the mounting tools 1, 2 are rotated by rotating a drive shaft, the warp 31 tends to spread in a direction of an arrow mark Y by applying tension to the tape 30. Required performance is displayed in the elastic joint by suppressing this movement of the warp by the weft 32.

Title: Catalyst composition for contact combustion
Inventor: KATOU YASUYOSHI
IPC: B01J37/02
Filed: 1982-08-23
Abstract: PURPOSE:To keep the temp. of a catalyst layer low and to prevent the deterioration of the catalyst due to heat, by forming a catalyst component layer promoting a combustion reaction on the surface of a heat transmitting material for the purpose of heat recovery, and transmitting rapidly the generated combustion heat. CONSTITUTION:A catalyst component layer 1 is formed to promote the combustion reaction on the surface of a heat transmitting body 2 for the purpose of heat recovery. The catalyst component layer 1 is made of a porous matter consisting of the active catalyst component in the combustion reaction, and well- known materials, such as mullite type porous matter supporting platinum metals (e.g. Pt, Pd, etc.) are applicable. For improvement of the adhesiveness of the surface of the heat transmitting material to the layer 1, it is advisable to carry out rugged finishing by well-known method such as knurling working. In this constitution, even if the temp. of the layer 1 becomes high by the combustion reaction, it does not become abnormally high, and the deterioration of the layer 1 due to heat can be prevented, because the heat is removed and recovered by the heating media flowing in the heat transmitting body 2.
