Title: Method for confirming static charge removed state with toner
Inventor: NOMURA NOBUO
IPC: G01N27/60
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To confirm the state before and after static charge removement visually by bringing positive and negative polarity toners of different color into contact with the surface of an object to be processed so that negative and positive-polar toners adhere to the parts having positive and negative charges respectively. SOLUTION: A plastic film 1 is moved by a guide roller 8 and the static charge is removed between a static charge removing electrode 3 and an ion attraction electrode 2 at a static charge removing section A before dust is removed at a dust removing section B. Equal quantity of red positive polarity toner powder and blue negative polarity toner powder are mixed previously and sprayed onto the surface of the film 1. The blue negative polarity toner powder adheres to a part having positive charges on the surface while the red positive polarity toner powder adheres to a part having negative charges and a clear color image red, blue and basic color of film appears on the film 1.  When a part of image is copied onto a white paper by means of a monochromatic copy machine, red and blue are converted into black having gray level indicative of the positive or negative potential and white indicates an uncharged part. Consequently, even the potential level can be indicated visually.

Title: Synchronization protecting circuit
Inventor: NAKANO YOSHIHIRO
IPC: H04L7/08
Filed: 1986-11-04
Abstract: PURPOSE:To facilitate establishment of synchronization and to cause out-of- synchronization to be hard to occur by making a first step coarse at the back protection, raising successively the accuracy, making the first step strict at the front protection and making the accuracy coarse successively. CONSTITUTION:When the intermediate output of the counter of a back protecting circuit 11, for example, an intermediate output 16 is a second step counter output, an intermediate output 17 is a third step counter output, an intermediate output 18 is a fourth step counter output, and an intermediate output 19 of the counter of a front protecting circuit is the first step counter output, and an intermediate output 20 is the second step counter output. Consequently, the detecting pattern of a synchronizing pattern is coarse to the first step at the back protection, a correct synchronizing pattern is successively detected, and when an unfair synchronizing pattern is detected once at the front protection, the detecting pattern is made coarse a little, further, when the circuit comes off from the detecting pattern, it works to make the detecting pattern coarse one more time. Thus, the probability that the delay in the establishment of synchronization occurs due to the code error, etc., in a transmission system and the out-of-synchronization generated can be widely reduced.
