Filed: 1989-05-26
Abstract: PURPOSE:To perform a surface mounting of an electronic component without generating a bridge even if the pitch of pads is very small by selectively precipitating tin-lead alloy only on the pads of a printed circuit board by a specific method. CONSTITUTION:After the pads 3 of a printed circuit board 1 are coated with tin powder-mixed organic acid lead salt paste 4, when they are heated, for example, at approx. 220 deg.C for 2-4min, tin-lead alloy 5 is selectively precipitated only on the surfaces of the pads 3.

IPC: H05B6/10
Filed: 1991-05-08
Abstract: PURPOSE:To obtain the device, in which deformation of wrinkle in bending part and flattening, etc., developed at the time of bending with high frequency heating can be prevented. CONSTITUTION:One end of the metal tube 6 to execute bending is fixed to an arm 3 rotatable around a rotary shaft 7 and the other end thereof is clamped with a pressing device, and further, this tube is guided with a supporting roll 4. Then, the metal tube 6 is inserted into an annular high frequency heating coil 1 connected with a high frequency power source without any contacting. On outer periphery of the annular heating coil 1, an auxiliary coil 2 is arranged together with the coil 1 only to back side of bending in the tube 6 to be worked. Under this condition, at the time of supplying the constant current from the high frequency power source 5, as the current density conducting the coil 1 and the auxiliary coil 2 is lower than the current density conducting only the coil 1, temp. difference between the back side and the front side in the bending, becomes at about 300 deg.C. In this result, by difference of deforming resistance due to temp. difference in deforming part, neutral axis of the bending is shifted to the back side and thin ned thickness ratio at the back side is restrained, and deformation of the bending part accompanied with the work is prevented.

Filed: 1979-10-12
Abstract: PURPOSE:To prevent feed of lapped transfer sheets with an image transferred on one side in advance, by providing a device for alternately placing a transfer sheet with a copied image on one side and a partition board. CONSTITUTION:When the first transfer sheet with an image copied on the first face is placed on copying sheet placing tray 1, plunger 6 in a stand-by state is excited on receiving a signal of sliding plate 2, electromagnet clutch 3 is slided, and magnetic lever 4 attracts partition board 5. A reflection type sensor microswitch detects this action, and this detection signal rotates lever 4 and board 5 in the direction shown with arrow C by a given angle, and stops them to the position shown by 4a and 5a. On stopping of lever 4, excitation of plunger 6 is released, clutch 3 is moved by pulling spring, board 5 is guided with guide rod 7 apart from lever 4. When clutch 3 strikes on stopper 15 and stops, its excitement is released, on the contrary, plunger 6 is excited, and attracts board 5 and lever 4. These repeated actions prevent feed of lapped transfer sheets in advance.

Title: Impurity introduction into semiconductor
Inventor: MURAMATSU SHINICHI
IPC: H01L21/22
Filed: 1988-06-01
Abstract: PURPOSE:To make it possible to form a thin impurity layer in a stable manner by a method wherein a semiconductor film or an insulating film is formed on a substrate using plasma, impurities are mixed into a plasmatic atmosphere at this time, and the impurities are contained not only in a semiconductor film but also in a semiconductor. CONSTITUTION:A semiconductor substrate is doped while a thin film is being deposited by discharging plasma in which dopant gas and a film-forming gas seed, monosilane and the like, for example, are mixed. In the deposition-film formation containing doping impurities using plasma, the doping makes progress in the initial stage in the same manner as the low temperature impurities doping using plasma. However, when the film reaches a certain degree of thickness, the doping does not make progress. As a result, a doping layer of a fixed depth can be formed in an excellent reproducible manner.

Abstract: PURPOSE:To quickly carry out both transmission reception requests given to the same terminal by using an input control part which receives an address independent of each address of each output control part and the output data from the output control part and at the same time performs a prescribed action based on a read command received from a CPU. CONSTITUTION:The output control parts (23-1) - (23-n) perform the prescribed processes to the terminals (4-1) - (4-n) respectively with each write command given from a CPU. At the same time, an input control part 24 performs the prescribed processes to the terminals (4-1) - (4-n) with each read command given from the CPU. In this case, an address independent of the parts (23-1) - (23-n) is set at the part 24. Thus the read commands are secured to all terminals (4-1) - (4-n) with the read command given to the single address. Then the corresponding read processes are attained regardless of the write processes given to the terminals (4-1) - (4-n). As a result, both transmission and reception requests can be quickly and simultaneously carried out to the same terminal.
