Title: Dc feeding unit of double section type
Inventor: SATOU HIROYASU
IPC: B60M3/00
Filed: 1982-12-03
Abstract: PURPOSE:To reduce harmonic components in a DC feeding unit such as a subway and feed it with high reliability by using a 12-phase rectification system in a feeding system and a double section system provided with an intermediate dead section. CONSTITUTION:The harmonic components contained in the current of the commercial frequency power supply 1 side is reduced by feeding every feeders 121 to 122 from 12-phase rectification system thyristor rectifiers 41 to 44. In addition, intermediate dead sections 112 and 114 are additionally spaced at regular intervals from the existing dead sections 111 and 113 and thyristor breakers 151 and 152 and the inverse parallel circuit of diodes 62, 64, 66, and 68 are connected in series and then desired running power is taken off from the respective both ends and bridged points. As a result, even when an electric motor car arrives while the feeder line is faulty, excessive bypass current is not applied to the electric motor car and the destruction of pantographs and dead sections can be prevented previously.

Title: Pulse laser oscillator
Inventor: NAKATANI HAJIME
IPC: H01S3/097
Filed: 1984-10-09
Abstract: PURPOSE:To enable high-repetition action even under low-speed flows of laser gas by a method wherein auxiliary discharge is generated only down the flow of laser gas below the main electrode. CONSTITUTION:The titled device performs almost the same action as the conventional device except that a capacitor 18 and auxiliary electrodes 19, 20 are on one side. Since the total capacitance of the capacitor 18 is equal to the parallel total capacitance of the capacitor of the conventional device, energy of the same power is injected to the part of the main discharge 14. However, since arc discharge does not generate in the flow above the main discharge 14, laser gas with the temperature increased by arc discharge and discharge products do not flow down from the upper side. Therefore, the gas flow makes it sufficient to force the laser gas with increased temperature and discharge products which generate at the part of the main discharge 14 away to the flow below the main discharge 14 before a next cycle, and the necessary velocity of gas flow is enough in a small degree.

Title: Heating device for reflow soldering
Inventor: MATSUMOTO KIYOSHI
IPC: B23K1/005
Filed: 1987-08-26
Abstract: PURPOSE:To act a hot blast and far infrared radiation at the same place, to uniformly heat a substrate and to miniaturize the device by storing a heater in the cylindrical container body formed by the substance easy to radiate a far infrared radiation and piercing a through hole on the outer periphery of the container body. CONSTITUTION:The heater 2 inside a container 1 receives the feed of an electric power, heating by Joule's heat and being subjected to a temp. rise. The gaseous body press-fed from a pump is thus injected from through holes 4, 4... after its temp. rise by being heated by the heater 2. The container 1 is simultaneously subjected to a temp. rise by receiving the radiation heat from the heater and the conduction heat due to hot blast, radiating a far infrared radiation with good efficiency. This hot blast uniformly heats the surface by striking to the printed circuit board just transferred and on the other hand the far infrared radiation radiated from the container 1 surface heats from the inner part by transmitting the electronic component mounted on the surface. The device can thus be miniaturized.
