Title: Finishing treatment method of printed wiring board, soft etching liquid, and printed wiring board
Inventor: KOBAYASHI SHIRO
IPC: C23F1/18
Filed: 1995-07-19
Abstract: PURPOSE: To prevent via hole from being disconnected by performing soft etching treatment using a solution containing soluble chloride and further forming a protection film containing CuCl on the surface of at least a desired part of exposed copper film. CONSTITUTION: A liquid solder resist is applied to both surfaces of a substrate 1 and is hardened and a solder resist 4 is formed on both surfaces of the substrate 1. A via hole 3 is covered with the solder resist 4. Then, the substrate 1 is degreased by an alkali solution or a surface-active agent and is softly etched. Chloride ions are added into the liquid being softly etched. Then, acid washing is made by dilute sulfuric acid and rust-proof treatment is performed by benzotriazol. Chloride ions couple with copper plating, thus forming a protection film 6 consisting of CuCl compound rust-proof film. The protection film 6 suppresses the etching of copper when the soft etching liquid condenses and prevents the via hole from being disconnected.

Title: Video recording and reproducing system
Inventor: SEKINE SHIGERU
IPC: H04N5/93
Filed: 1983-09-30
Abstract: PURPOSE:To obtain stable still pictures despite the disturbance of H signals by storing not only the picture element information but the corresponding H signal to a memory and obtaining the still picture information from the H signal and the picture element information read out of the memory. CONSTITUTION:A write timing signal WT is delivered from a timing signal generating circuit 13 synchronously with the vertical synchronization of a video signal VID given from an FF16 and from an H-position preceding place within a period H with a prescribed time width. The signal VID undergoes A/D conversion or is written to a memory based on the signal VID according to the signal WT. Thus the video signals including the signal H are recorded to the memory. In a reproduction mode, the data are read out of the memory and undergo D/A conversion. As a result, a reproduced video signal contains the signal H. This signal H is used to a video reproducer. Thus the video reproduction is possible with the same signal H as a video record mode. In this way, the shift among pictures is prevented.

Title: Power controller
Inventor: SAKIZAKA TAKESHI

Filed: 1981-11-13
Abstract: PURPOSE:To improve the power control, by connecting a limit pulse generating circuit which generates the limit pulse to make thyristors conduct alternately to a trigger control circuit of the thyristor. CONSTITUTION:When an object to be heated is put into an oven 1 from the side of a heater 2, the temperature inside the oven 1 lowers at the area near the heater 2. Thus a thermoelectric element 12 requests a corresponding trigger control circuit 15 to produce a trigger pulse in a shorter cycle. On the other hand, a temperature disturbance detector 17 detects that the object to be heated is put into an oven 1 and then informs this fact to a limit pulse producing circuit 18. Thus the circuit 18 transmits continuously the limit pulses of different ratios until the disturbance of temperature is eliminated. As a result, both thyristors 5 and 10 conduct alternately to supply a large amount of electric power to the heater 2 and a small amount of electric power to a heater 7 respectively.

On the other hand, when one side S1 of an alternating current 10 is set to a negative side and the other side S2 of the alternating current 10 is set to a positive side, no current flows because of the diode D3. When a trigger current is fed to the input side of a photothyristor PS1, the PS1 is turned on and the electric charge of C1 is discharged by way of the primary coil of TR1.  In this condition, the first coil of TR1 and the C1 are short-circuited and are resonated by PS1 and the reverse current flow through a diode D4 and a pulse current is boosted by the PS1 so that a spark is generated in a discharge gap by way of the transformer TR1.
