Title: Nc router automatic processing system
Inventor: SUZUKI MICHITOMO
IPC: B27C9/00
Filed: 1990-11-07
Abstract: PURPOSE:To make search of a sacrificial plate unnecessary and to make positioning of the sacrificial plate and also a processing plate unnecessary by actuating each control apparatus based on a command from a main control apparatus, positioning at first a sacrificial plate having been transferred on a table of an NC router by means of a robot and furthermore positioning a processing plate on the sacrificial plate and processing it. CONSTITUTION:When a processing plate 3 and a sacrificial plate 7 are placed on a pallet 4 by means of a traverser 8 from a warehouse 1 for the processing plate and are conveyed to a conveyer 11, a robot 14 is actuated and the sacrificial plate 7 is at first positioned and then, the processing plate 3 is positioned on the sacrificial plate 7 and is processed. Therefore, the sacrificial plate to be necessary for the processing plate 3 is always conveyed with the processing plate 3 and when a processing plate 3 on the next pallet 4 is processed, if the sacrificial plate 7 which has been already positioned can be used, a sacrificial plate which has been conveyed afterward can be excluded and therefore, time for positioning can be shortened thereby.

Title: Ink jet printing head
Inventor: MIYAMOTO TSUTOMU
IPC: B41J2/045
Filed: 1990-11-07
Abstract: PURPOSE:To obtain an ink jet printing head which has an excellent high frequency response property and favorable discharge efficiency by providing an ink counterflow preventive mechanism in an ink chamber. CONSTITUTION:A plate-shaped piezoelectric element 2 is mounted on the top of an ink chamber 1, and a valve 12, which is an ink counterflow preventive mechanism, is formed, to correspond with a nozzle hole 5, in the ink chamber 1. At the time of ink discharging, since pressure in the ink chamber 1 becomes higher than that of an ink feeding part 3, the valve 12 is closed, and almost all the ink in the ink chamber 1 is ink-discharged without counterflowing to the ink feeding part 3 side, and discharging with high efficiency becomes possible. When the inside of the ink chamber 1 is returned to the original condition, the pressure in the ink chamber 1 becomes lower than that of the feeding part 3, and therefore, the valve 12 is opened, and the ink is fed in the ink chamber 1. By making the passage resistance from the nozzle hole 5 to the ink chamber 1 larger than the passage resistance from the ink feeding part 3 to the ink chamber 1, drawing of air bubbles from the nozzle hole 5 becomes hard to be generated at the time of ink feeding. That is, it is made possible to return the condition in the ink chamber 1 to the original condition at a high speed, and ink-discharging responded at a high speed.

Title: Pressure sensor
Inventor: SHOJI MASATO
IPC: G01L9/16
Filed: 1988-11-30
Abstract: PURPOSE:To obtain pressure sensor with higher sensitivity but limited in hysteresis by providing a through hole in a amorphous magnetic alloy to bond. CONSTITUTION:A pressure is transmitted to a pressure chamber 3 from a pressure introduction port 2 and a stress is applied in such a direction to expand the pressure chamber 3, which causes a deforming part 4 to very to deform an amorphous magnetic alloy 6 bonded on the surface thereof. With the deformation, a magnetic permeability of the amorphous magnetic alloy 6 changes by an inverse magnetostrictive effect. This change is detected with a pressure detection coil 8 as such in inductance and a difference from a differential coil 9 is taken with a detection circuit 13 to obtain a pressure. As shown in Fig. (a), for example, 12 through holes each 1mm wide and 5mm long are provided on the amorphous magnetic alloy. A broken winding is developed along the length to match a diameter of a pressure sensor to create a shape as shown in Fig. (b) and then, bonded on a body. It should be noted that a desired change in the through hole yields the same effect when a total area of the through holes is about 3-10% of the area of the amorphous magnetic alloy.
