Title: Stabilizer for floating platen
Inventor: RICHIYAADO ARAN MERIMAN JIYUNI
IPC: B41J11/02
Filed: 1992-03-19
Abstract: PURPOSE: To give an apparatus which is used for a print head in connection with a floating platen and eliminates ink stains and others. CONSTITUTION: A print head 24 is mounted on a carriage 26. The carriage has a paper compensation member 50 which is fixed to it and contacts the uppermost surface of a document to be printed. The compensation member somewhat slants the printing surface of a platen 28 and causes ink stains or printing disarrangement by the print head 24. In order to eliminate the inclination caused by the compensation member, a stabilizer 58 is used. In this way, the printing surface of the platen 28 is maintained in parallel to the print face of the print head 24. In an example, the print head 24 is a wire matrix printer. The stabilizer 58 includes the first and second springs fixed to the platen 28, and the springs collaborate with a channel 38 on which the platen 28 is mounted.

Title: Liquid level detector
Inventor: NOZAWA YOSHIE
IPC: G01F23/28
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To accurately detect the liq. level position for a long time even in a liq. such as treating liqs. contg. chemicals, without having a movable part for detecting the level position. SOLUTION: When a liq. is gradually stored in a liq. store tank, a sound wave is hardly transmitted because of a medium being air between a horn 24 and a receiving part 32, and a receiving part 32 sends a weak electric signal including 0 to a controller 40, resulting in an off-signal (no detection of the liq. level). When the liq. is stored up to a liq. level detector 10, the medium between the horn 24 and the receiving part 32 changes to the liq. When the liq. passes over this interface, the sound wave intensively conducts to the receiving part 32, and this part 32 sends an intensive electric signal to the controller to result in an on-signal (liq. level detection).
