Patent JP-H03218022-A (JP)
Title: Semiconductor integrated circuit
Inventor: MITSUYA KAZUYUKI
IPC: H01L21/82
Filed: 1990-01-23
Abstract: PURPOSE:To prevent the generation of failures caused by interlayer short-circuiting, improve the reliability of multilayer wiring structure and the yield of products, and prevent the decrease of current capacity, the potential drop, etc., caused by thinning a wire, by interlayer connecting the thinned wire part and spare wirings. CONSTITUTION:A first wiring 16 and a second wiring 17 are stretched by using wide line width 18 corresponding with the current capacity required for the respective output buffer transistors 13, 14, in the part where wire overlapping is not necessary because there is areal margin or either one of the wirings 16 or 17 is unnecessary. In the part where both of the wirings approach and overlap each other in order to be stretched by using the wide line width 18, the respective wirings 16, 17 are formed narrower than the line width 18, and stretched by using narrow line width 19. On the upper layer or the lower layer of the respective wirings 16, 17, spare wirings 20, 21 are arranged and electrically connected with the wirings 16, 17. Hence the current capacity of the part stretched by using the line width 19 can be nearly equivalent to that of the part stretched by using the line width 18. Thereby the generation of failures caused by interlayer short-circuiting can be prevented, the reliability of a multilayer wiring structure and the yield of products can be improved, and the decrease of current capacity, the potential drop, etc., caused by thinning a wire can be prevented.

Title: Rectilineal kerosene-gasifying burning device
Inventor: IWAI KAZUMI
IPC: F23D11/02
Filed: 1979-02-13
Abstract: PURPOSE: To obtain uniform fuel-air mixture by composing a passage of mixture inside the main body of a burner in a zigzag form and further composing the same so that the mixture is led to a flame outlet through shrinking and extending processes.  
     CONSTITUTION: Inside the main body 13 of a burner the kerosene evaporated by a heating plate 15, a part of which is mixed with the primary air, strikes against the other side wall 13B of the main body 13. Here the flow is turned reversely and, moreover, passes through a loosely restricting part 35 formed on the 1st flow- regulating plate 33. The mixture then enters a flow-shrinking chamber 31 and flows forward, being gradually accelerated and mixed. Since the flow-shrinking chamber 31 is formed with the 2nd flow-regulating plate 34 arranged at a certain angle to the 1st flow-regulating plate 33, the mixture contraction is made at the outlet of the chamber. At the downstream of the mixture contraction through a restricting part 36 is formed a sharply-extending chamber 32 large enough, which leads to the flame outlet.

Abstract: PROBLEM TO BE SOLVED: To provide an elastic modulus measuring device simply determing the elastic modulus of a matter. SOLUTION: When a subject mounts a pulse wave detecting part 9 to the finger tip part of his finger to pressurize a pressure sensor 110, a CPU 4 obtains the DC component of a photodetective signal LS and stores it in a calibration table 50 while corresponding with a pressure level. After this, the CPU 4 calculates each threshold value to be reference at the time of grading pressing force based on the maximum value P max of the pressure level and the table 50 and houses it in a pressurizing information threshold value table 51. Then pressurizing information OJ is generated by referring to the table 51. In addition, displacing information X at the time of pressurizing is calculated by double- integrating acceleration information AJ from an acceleration sensor. After this, the CPU 4 calculates elastic modules K1 based on pressure information OJ and displacing information X.

Filed: 1989-01-23
Abstract: PURPOSE:To realize excellent balance among strings and to generate a clean and deep sound while eliminating variation in sounding among electric guitar products by arranging a pickup so that magnetic flux exiting from the pole piece of the pickup passes a specific intermediate point. CONSTITUTION:When a string 10 vibrates, the number of pieces of magnetic flux cross-linked with coils wound around bobbins in pickups 30 and 32 varies and a current corresponding to the variation flows to the coils. Fine current variation is amplified by a guitar amplifier and transduced into a sound. At this time, positions at major 3rd, perfect 4th, and perfect 5th consonant intervals are regarded as the arrangement positions of the pickups 30 and 32 to not only obtain a large harmonic overtone content rate of pickup outputs, but also prevent a dissonance which is offensive to the ear from being generated resulting from the arrangement positions. Namely, a round and deep sound is generated.

Abstract: PURPOSE:To reduce the size of an optical pickup system by providing a polarization beam splitter to optical paths so that an optical path from a semiconductor laser to the polarization beam splitter and an optical path from the polarization beam splitter to detector cross each other. CONSTITUTION:A parallel prism 15 is inserted into the optical path between the condenser lens 12 and photodetecting element 14 for detection of an optical detection system.

Filed: 1990-01-25
Abstract: PURPOSE:To prevent inability of insertion into a mother board and the increase in mounting height on a printed board by forming a cut-out part at the center of the lower edge part of an electrode for a lead terminal. CONSTITUTION:An electrode 20 for a lead terminal is formed along the lower edge of a printed board 2 comprising ceramics, epoxy glass or the like. A cut- out part 21 in a recess shape is formed at the central part of the lower edge of the electrode 20.

A board-exposed surface 25 is formed between the cut-out part 21 and the lead terminal 5. Therefore, even if the board is submerged into a dipping tank under the state wherein the lead terminal 5 is held with the electrode 20 for the lead terminal and then lifted, solder stagnation is not formed between the lower surface of the branch part 5a and a leg part 5b of the lead terminal. Thus, inability of mounting on the mother board and the increase in mounting height on the printed board 2 can be prevented.
