Title: Printed wiring board conductive foil
Inventor: YOSHIMOTO HIRONORI
IPC: H05K3/34
Filed: 1993-11-25
Abstract: PURPOSE:To prevent solder bridges from being produced by a method wherein a conductive foil provided onto a printed wiring board to solder the leads of an electronic part is formed into a teardrop shape, and the teardrop-shaped conductive foils are alternately arranged changing the position. CONSTITUTION:A conductive foil 1 used for soldering the leads of an electronic part is formed into a teardrop shape which has two opposed sides, a wide side 5A and a narrow side 5B, and the teardrop-shaped conductor foils 1 are alternately arranged on a printed wiring board changing position. The leads of an electronic part are soldered to the conductive foil 1 through a soldering gun method, a reflow process, or a flow process. As mentioned above, teardrop- shaped conductor foils are alternately arranged on a printed wiring board changing positions so that the wide side of the conductive foil where molten solder is concentrated is set distant from an adjacent conductive foil, and consequently a solder bridge can be prevented from being produced.

Inventor: NAKAO ICHIRO
IPC: H01L21/304
Filed: 1990-10-31
Abstract: PURPOSE:To improve the efficiency of cleaning work by a method wherein a carrier containing substrates and having a liquid vent window is disposed in a cleaning vessel while a path of a cleaning solution and an inert gas is formed between the sidewall and the carrier so as to cause a flow of cleaning solution from the liquid vent window to the path. CONSTITUTION:The title cleaning device is structured of a carrier containing substrates 5 and having a liquid vent window on the sidewall thereof disposed in a cleaning vessel making a specific gap with the sidewall 1 as well as a path of a cleaning solution and an inert gas to be formed between the sidewall 1 and the carrier 4 so that the cleaning solution may run out from the liquid vent window to the path by the rising flow of the inert gas. Accordingly, the flow velocity outside the carrier 4 is accelerated by the bubbles 11 of the inert gas so that a flow may be caused between the path between the sidewall 1 and the carrier 4 and the liquid vent window 6 thereby enabling the flow velocity near the inside of the carrier 4 to be accelerated. Through these procedures, the substrates 5 can be cleaned up perfectly and efficiently.

Title: Storage device
Inventor: SENGOKU SHINJI
IPC: G11B20/10
Filed: 1985-12-27
Abstract: PURPOSE:To detect previously the possibility of the occurrence of erasure of stored information being slightly high by providing a detecting circuit which inputs the rotational pulse signal of a rotation detector and detects the start time of a rotating device becoming long. CONSTITUTION:When a head 6 floats normally, the pulse interval of an output signal (a) becomes constant right after the start of the rotating device 2; and an output signal (d) varies from logic 1 to logic 0 immediately and then an output signal (e) becomes a signal with logic 1. Consequently, an output signal (f) still has logic 0 and no pulse is outputted from an AND gate 24. When the extent of damage to the head 6 and a disk 3 increases, the pulse interval of the output (a) becomes longer right after the start of the rotating device than normal. Consequently, the output signal (e) becomes a signal with logic 1 and the output signal (d) becomes a signal with logic 0, so a pulse contained in the output signal (f) of the AND gate 24 is outputted as a detection signal.

Abstract: PURPOSE:To make it possible to measure rotational properties of a material to be measured by detecting laser light beams which are reflected by a fixed mirror, a rotary mirror and the material to be measured. CONSTITUTION:Laser light 8 emitted from a laser device 1 is split through a half prism 2. One laser light is reflected by a material to be measured 5 and a vertical reflecting mirror 9 through fixed mirrors 4 and 4'. The light advances in the reverse direction on a light path and illuminates a two-dimensional sensor 6. The other laser light is reflected by a rotary mirror 3, the material to be measured 5 and the mirror 9. The light advances in the reverse direction on the light path and illuminates the sensor 6. When the material to be measured 5 is rotated or performs rotating oscillation, pulses having a constant interval are generated from pixels at the reference positions of the sensor 6 based on the laser light through the fixed mirrors 4 and 4' and the laser light through the rotary mirror 3. The rotary angle and the changing characteristic of the rotary angle of the material to be measured at this time can be computed based on the time difference and the set angle of the rotary mirror.
