Title: Liquid-jet head and its manufacture
Inventor: HASEGAWA KAZUMASA
IPC: B41J2/16
Filed: 1989-03-17
Abstract: PURPOSE:To realize a liquid-jet head easy to form multi-nozzles with high density and also to restrict the positional deviation considerably small between a piezoelectric element and a pressure chamber by forming a liquid guide pass, a piezoelectric element and the like continuously by photolithography technique. CONSTITUTION:A pattern 102 is formed on an optional substrate 101. A buffer film 103 is formed all over the substrate 101. When the pattern 102 is removed, empty holes 104 are formed in the film 103. The buffer film may be made of SiO2 or the like. Thus, the empty holes 104 which become guide passages for a liquid and empty holes 108 which serve as a pressure chamber are formed linearly. Subsequently, an electrode 105, a piezoelectric body 106 and an electrode 107 are formed through lamination. These components 105-107 form a piezoelectric element. The electrodes 105 and 107 may be made of Pt or the like on the pressure chamber 108. The piezoelectric body 106 may be made of PZT etc., through sputtering method or the like.

Inventor: KATAOKA SHIGERU
IPC: F16L33/20
Filed: 1989-03-17
Abstract: PURPOSE:To enable the assembly with a conventional method even if a joint main frame is made of synthetic resin by forming a width across corners of a nut part of a joint fitting smaller than the outer diameter of a sleeve. CONSTITUTION:A terminal of a handle fitting 1 and a hose H is inserted to a ring space S between a nipple part 12 of a joint main frame 10 and a sleeve 20 to be set in a conical dies D of a fastener and is pressed from the other end side of the main frame 10. The sleeve 20 is slid along a taper surface of the dies D and is while deformed to reduce its diameter by this pressing, and the hose H is pinched to be pressed with the sleeve 20 and the nipple part 12 of the main frame 10 to comprise the sufficient drawing strength. At this stage, since a pusher P of the fastener pressing the joint fitting 1 from the other end side to one end side in the axial direction abuts to an inner flange 21 side end surface of the sleeve 20 to press it, the pressure of the fastener is not applied directly to a nut part 11 of the main frame. The main frame 10 is not damaged at the time of fitting the hose H even if the main frame is made of synthetic resin, and the secure assembly can be performed.

Title: Method of tracing virtual tracking
Inventor: TASHIRO KATSUO
IPC: G05B19/418
Filed: 1986-03-26
Abstract: PURPOSE:To realize a tracking capable of tracing a virtual tracking and equivalent to a control system and to secure information security in case of emergency by making a host computer generate a target on a prearranged facility route and running along the target according to passing point information. CONSTITUTION:A host central computer has as virtual table information all patterns and routes having possibility of tracking, generates a target (a pointer on a memory) based on point information sent from a control system on the route, runs the target, and traces material movement while tallying with tracking information (1) through (n). After storing tracking information (1) through (n) necessary when receiving initial data in a file, it has only to advance the target when a passing point information is received, to determine the end of a tracking when the target is finished, and to renew related files. Accordingly, even in case of trouble in the control system in the middle of tracking, the tracking information can be secured with the host computer and the control system can be restored based on the data of the information.

Title: Liquid-jet recording apparatus
Inventor: TERASAWA HIROHARU
IPC: B41J2/175
Filed: 1989-03-17
Abstract: PURPOSE:To positively fill the ink by providing a control means for controlling an opening/closing means corresponding to a suction mode of a suction recovering device in a liquid-jet recording apparatus equipped with said opening/ closing means of ink and suction recovering device for sucking the ink from a discharge port by the negative pressure. CONSTITUTION:When a solenoid 56 is not magnetized, a lever 53 is at a horizontal position and a valve 52 is at a neutral position, thereby allowing the ink to freely pass through within a joint 51. When a carriage 2 is moved to a home position H and stopped there, a cap holder 21 of a suction recovering device is brought into close contact with a recording head 1 to cover a nozzle portion. Then, when the solenoid 56 is energized, an armature 56A draws an end of the lever 53 downwards and consequently the other end of the lever 53 raises an opening/closing leaf spring 58. Accordingly, the valve 52 is turned in a counterclockwise direction and a spherical body within the joint 51 clogs an exit of an ink supply passage 60. At this time, a pump 28 is driven to transmit the negative pressure generated thereby to a cap 22. Thus, the ink within the nozzle portion is discharged into the cap.

Title: Gate turn-off thyristor and its manufacture
Inventor: SENNENBARA NOZOMI
IPC: H01L29/417
Filed: 1994-04-04
Abstract: PURPOSE:To realize the improvement of a breakdown strength and an ON- resistance and the improvement of a turn-on loss and a di/dt-resistant amount in a compatible manner. CONSTITUTION:An n-buffer layer 12 is exposed locally on the rear surface of a semiconductor substrate 160, and a polysilicon addition resistance layer 104 is formed so as to cover its exposed face. An anode electrode 101 which covers the rear surface of the semiconductor substrate 160 is connected to a p-emitter layer 11 and the addition resistance layer 104. As a result, since the n-buffer layer 12 and the anode electrode 101 are connected via the addition resistance layer 104, a gate trigger current is low. As a result, a turn-on loss is low, and a di/dt-resistant amount is high. At the same time, since the n-buffer layer 12 is formed, a breakdown strength and an ON-resistance are good. Thereby, it is possible to improve the turn-on loss and the di/dt-resistant amount without spoiling the breakdown strength and the ON-resistance.
