Title: Method of soldering on back of printed board
Inventor: IZAWA ISAO
IPC: H05K3/34
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent defective soldering from being generated on the back of a printed board and to make it possible to raise reliability of the printed board. SOLUTION: A mask 5 made of stainless steel plate is superposed on the back of a board, which is tacked temporarily with electronic components 3 and 4 with a bonding agent. Apertures 5a for forming a gap of 0.5 mm or thereabouts between the outer peripheries of the leads 2a of the components 2 are formed in this mask 5. Apertures 5b and 5c are formed in the soldering parts of the mask 5 to coat a flux also on the other electronic components 3 and 4. When powder solder subsequent to that is made to adhere on the soldering parts, the mask 5 may be exchanged for a new mask which is not adhered with the flux.

Title: Production of porous mold material
Inventor: KATO TATSUHIKO
IPC: C22C1/08
Filed: 1992-07-17
Abstract: PURPOSE:To reinforce the mechanical properties and prolong the life by heating a molded and sintered body composed of powder of a stainless steel and short fibers which are respectively specific in a nitrogen atmosphere. CONSTITUTION:The molded and sintered body is produced from the mixture composed of the powder essentially consisting of the powder of the low-C- and low-N-content Cr stainless steel and the short fibers of the stainless steel having 20 to 100mum size in terms of diameter and 0.4 to 3.0 mm length. This molded and sintered body is heated in the nitrogen atmosphere and is nitrided, by which content of the nitrogen is specified to 1.0-1.5%; thereafter, the sintered body is rapidly cooled down to <=250 deg.C at a cooling rate of >=0.5 deg.C/min average cooling rate, by which the excessive precipitation of the nitride and the transformation of the austenite phase to a ferrite phase are prevented. The austenite phase is partly transformed stably to the martensite phase. The austenite phase remaining at room temp. is further reheated at 500 to 650 deg.C and is transformed to the martensite phase, by which the workability is improved. The strength is also improved by the precipitation strengthening effect of the nitride.

IPC: B62D3/12
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a steering device capable of stably relaxing impact load taking place at a steering shaft though the device is compact in constitution. SOLUTION: In this steering device 100, a disc spring 105 is interposed between a first rack support 104 and a second rack support 106, when it is subjected to force in the direction that a pinion 11a is parted from a rack shaft 112 at the time of usual steering, the first and second rack supports 104 and 106 act as a solid body each, however as they are so designed as to be relatively moved when they are subjected to impact load, they can stably absorb impact load only when impact load takes place without hindering a rack support function. Furthermore, since the disc spring 105 as mentioned above can be incorporated in the inside of the rack support, the steering device can thereby be made more compact.

Title: Data collecting system
Inventor: MUNAKATA KOUJI
IPC: H04L12/40
Filed: 1981-12-25
Abstract: PURPOSE:To improve the working ratio of a system, by sending an adjustment request to a master POS from each slave POS, storing own data of each slave POS after an adjustment and then collecting properly the data by the master POS. CONSTITUTION:A master POS having a bubble memory 7 is connected to plural slave POS8-10 to transfer the communication. These POS8-10 have their exclusive bubble memories 11-13 respectively. These slave POSs transmit the adjustment request signals to the master POS when they perform the adjustment and at the same time store their own adjustment data in their exclusive bubble memories. The master POS6 calls properly the POS8-10 which had the adjustment requests at intervals of its working and transfers the data within the memories 11-13 to a bubble memory 7. The master POS6 transmits the data to a host when necessary. Thus the operation of each POS is never restricted. As a result, the overoll working ratio is improved for a system.
