Title: Heat exchanger
Inventor: SHIMOKAWA NAOKI
IPC: F25B39/02
Filed: 1984-06-20
Abstract: PURPOSE:To prevent an outdoor side finned aluminum heat exchanger from freezing by a structure wherein the pitch of the fins at the lower part of the outdoor side heat exchanger is made coarser so as to prevent the surface tension from applying and not to make droplets adhered to the heat exchanger stagnant at the lower part of the heat exchanger. CONSTITUTION:During heating operation, an outdoor side heat exchanger 1 acts as an evaporator and dew is formed on the surfaces of fins. The dew increases its size into droplets, which flow downwards by gravity between the fins in the course as indicated with the dot and dash arrow. When the droplets reach the lower end, the droplets fall to a base plate 2 side, because the pitch of fins at the lower part of the outdoor side heat exchanger 1 is made coarser and consequently no surface tension acts across the fins. Accordingly, no stagnation of water occurs at the lower end part of the outdoor side heat exchanger 1, resulting in causing to freeze no water at the lower end of the outdoor side heat exchanger, even when the temperature of the fins of the evaporator turns to be 0 deg.C.

Title: Attaching method for semiconductor element
Inventor: KOREEDA SHIYOUICHI
IPC: H01L21/52
Filed: 1979-10-02
Abstract: PURPOSE:To prevent oxidation of the surface of solder and a substrate by a method wherein the substrate on which a semiconductor element is attached is heated, a fixed quantity of fused solder is dripped and the semiconductor element is attached to the substrate with the fused solder. CONSTITUTION:At the same time when a substrate 8 is moved to leftwards, a solder supplying section 11 is shifted to a desired position. And solder is dripped from the solder supplying section 11 on the substrate 8 being heated by a heating section 9 and then the substrate is returned to its former position. Subsequently, an element supplying section 12 is shifted to the same desired position as above, the element is adhered on the dripped molten solder and the element supplying section 12 returns to its former position. These movements are repeatedly performed. Hereby, as an oxide film is hard to grow on the semiconductor surface, the wetting property of solder to the semiconductor element is improved, and radiation effect from the semiconductor element can be increased. Also, as the substrate is heated for a relatively short time, the plated surface of the substrate is not oxidated and an excellent soldering can be performed.

Abstract: PURPOSE:To ensure the minimum necessary starting ability even when friction coefficient is very low by establishing a lower limit of a target slip rate or slip speed based on a friction coefficient between a road surface and a wheel for the torque control of a driving wheel. CONSTITUTION:A friction coefficient between a road surface and a wheel is detected by a means A. Then a target slip rate or slip speed is calculated by a means B based on the detected friction coefficient. When a driving wheel is slipped, the speed of a driving wheel is determined based on the target slip rate and slip speed, and the torque of the driving wheel is controlled by a means C to keep the speed of the driving wheel. Moreover a lower limit of the target slip rate or slip speed is established by a means D. The torque of the driving wheel is controlled based on the target slip rate or slip speed to which the lower limit is given by this. It is thus possible to ensure the minimum necessary starting ability even when the friction coefficient is very low.
