Patent JP-H10294337-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: YAMADA HIROSHI
IPC: H01L21/60
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To relieve the strain due to stress of bumps due to the difference between the thermal expansion coefficients of a semiconductor chip and a circuit wiring board by a method wherein high-melting point solder alloy layers, which are firm to the strain due to stress, are selectively arranged only on the side of the board and the compositions of the alloy layers are changed in a stepwise manner to the side of the chip. SOLUTION: Bump electrodes 3 are respectively constituted of a first solder alloy layer 4 having a first melting point, a third solder alloy layer 5 having a third melting point, which is lower than the first melting point and is higher than a second melting point, and a second solder alloy layer 6 having the second melting point, which are arranged in order from the side of a circuit wiring board 2. Accordingly, as the solder composition alloy layers, which are firm to the strain due to stress, are arranged on the side part, in which the strain due to stress is generated most greatly, of the board 2, the strain due to stress of bumps is relaxed.  Moreover, as the melting temperature of the layer 5 is within the ranges of the melting temperatures of the layers 4 and 6, a semiconductor chip 1 can be reliably bonded to the board 2 without needing a flux by heating simultaneously the chip 1 and the board 2 within the ranges of these temperatures to pressure-weld the alloy layers to each other.

IPC: F16K17/34
Filed: 1979-08-13
Abstract: PURPOSE: To prevent occurrence of such an accident as gas poisoning or gas explosion, etc., by enabling a spherical valve to automatically shut off a valve seat only when a gas flow exceeds a prescribed flow rate.  
     CONSTITUTION: When a shutter 2 is in a blocked position, a spherical valve 26 is located on the bottom in a tapered pipe 22. When a knob of a gas cock is set to open, position and gas starts flowing from a pipe-side passage 30 in the direction of a hole 20 led to the shutter 2, in the noraml condition, the spherical valve 26 sits still as depicted in the sketch and would not sotp the gas flow. However, if the load side is released without any resistance at all, pressure differences are generated at the front and exit of an open-and-close valve seat 21 and also at the front and exit of the spherical valve 26, and therefore, when a gas flow rate becomes excessively high, the spherical valve 26 is sealed by the open-and-close valve seat 21 to shut off the gas passage.

Title: Data transmission centralized controlling system
Inventor: GOTOU AKIYUKI
IPC: H04Q3/60
Filed: 1982-06-16
Abstract: PURPOSE:To use a DTl effectively, by selecting one DTI for transmitting and receiving an order out of all DT1s (IF circuits of a data transmission circuit) connected between a parent station and a remote station. CONSTITUTION:A channel (CH) confounding switch CH-SW disperses speaking signals of the 30CH of a 30CH encoding circuit CODEC for all DTl. Therefore, if one of the DTls fails, only 2CH or 1CH becomes impossible to use out of 30CH of CODEC so that the DTl can be effectively used in comparison with a conventional system. The order transmission and receiving between both stations becomes possible, if one of 16DTl is normal. When transmitting an order, the order extracted by an order extracting circuit lNS/DRP on the HO side of a parent station is transmitted through BF-DRPQ-l/O-CPU and transmitted to the RO side of the remote station through CPU-ORDSND-GATE-(D)MPXO- DT100 (if being transmitted and received through 100). It is transmitted through DT100-(D)MPXO-SEL-ORDREC-CPU on the RO side of the remote station.

IPC: H04N1/04
Filed: 1984-05-23
Abstract: PURPOSE:To attain miniaturization and light weight by allowing a light emitting diode to receive a reflected light from an original of a region corresponding to the light emitting diode and converting the light into an electric signal and repeating the said operation sequentially. CONSTITUTION:A light emitting diode LED array 10 arranged on a substrate 11 is in contact with an original 8 via a transparent protecting layer 12. A light shield layer 13 is provided on a protection layer 12 and a slit form lighting window 14 is formed to a part to improve the resolution in the sub-scanning direction. A reverse voltage is applied to an optional LED(Dn) and a forward current flows to all remaining LEDs. When an incident luminous amount is less to the LED, no current flows even if a reverse voltage is applied, and when the incident luminous amount is increased, a reverse current flows. Thus, the reflected luminous amount differs from density information of a region R of the original 8 corresponding to the LED(Dn) and the current value flowing to the LED(Dn) is changed, then when the current change is extracted as the voltage change across an external resistor, it is possible to use the LED as a photodetector.
