Title: Ink-jet recording head
Inventor: FUKAZAWA NAOTO
IPC: B41J2/045
Filed: 1988-09-27
Abstract: PURPOSE:To reduce the return of ink to the ink feed side, and to stabilize the discharge of ink by partially throttling the width of an ink feed in the vicinity of the inlet of an ink pressure chamber and constituting an ink backflow preventive section. CONSTITUTION:Sections near the inlets of ink pressure chambers 2 in ink feeds 2 on a substrate 1 are throttled in the width direction, thus organizing backflow preventive sections 2a. When such backflow preventive sections 2a are mounted, no only passage resistance but also inertial resistance by the mass of ink can be balanced before and behind the ink pressure chambers 3 because the passage resistance on the ink supply side is adjusted easily, and the quantity of ink escaping to the ink supply side and the quantities of ink ejected from ink nozzles 5 are balanced when a piezoelectric element 10 is driven, thus stabilizing the discharge of ink. According to the backflow preventive sections 2a, the movement of ink in the direction of the nozzles and the movement of ink to the ink supply side are equilibrated, thus simultaneously satisfying the increase of discharge efficiency and the shortening of the ink return time after discharge.

Title: Strong brazing joint of silicon carbide ceramic material to metal and method for making the joint
Inventor: TAMAI FUJIO
IPC: C04B37/02
Filed: 1993-09-03
Abstract: PURPOSE:To provide a method for making a strong brazing joint of a silicon carbide ceramic material to metal and obtain a strong joint of a silicon carbide ceramic material to metal. CONSTITUTION:When making a brazing joint of a silicon carbide ceramic material to metal using an active brazing metal, an intermediate layer composed of Si3N4/Ni/Mo/Ni or Si3N4/Ni/W/Ni is placed between the members to be joined, wherein the Si3N4 layer faces to the ceramic material. In this joint, the application of a barrier layer composed of Si3N4 as an intermediate layer touching the silicon carbide ceramic material prevents the formation of a fragile corrosion region by Cu contained in the active brazing metal or Ni diffused from a stress relaxing agent in the silicon carbide ceramic material. Accordingly, the obtained joint of a silicon carbide ceramic material to metal has such a high joint strength and high reliability as not to be available in a conventional brazing joint.

Title: Projection aligner
Inventor: TAKAHASHI KAZUHIRO
IPC: G03F7/207
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To predict accurately and correct the amount of fluctuation of the optical characteristics of a projection optical system by a method wherein correction coefficients, which are changed, are preserved as data in every reticle and the amount of fluctuation of the optical characteristics is predicted using the preserved correction coefficients in every reticle. SOLUTION: The face of the focus of a projection optical system 4 is measured by a TTL focus system 50 and a correction coefficient Da in every reticle is corrected. When an exposure of one lot component ends, a reticle 2 is housed in a reticle cassette. At this time, the newest correction coefficient Da used in an optical characteristic prediction part 18 is simultaneously preserved in a reticle data preservation part 16 as data to correspond to the reticle 2. Then, in the case where an exposure is performed using the same reticle, the newest correction coefficient Da is used. In such a way, as the correction coefficients in a predictive calculation are held so that they are preserved and used in every reticle, the accuracy of the predictive calculation can be enhanced.

A conductive film 6 is deposited, and sub-gates 7, 7' are left on both side walls of the main gate 4 through a dry etching method. As<+> ions are implanted, employing these sub-gates as masks, thus shaping second diffusion layers (D2) 8, 8' in intermediate concentration. D1 is aligned in a positional shape in approximately the same size and opposed through the sub-gates 7, 7' and the gate oxide film as shown in the figure. When D2 is formed at approximately the intermediate concentration, insulating-film side walls 9, 9' are shaped along the sub-gates 7, 7', and high-concentration diffusion layers D3 are formed, using the side walls 9, 9' as masks.

Title: Bonding device for inner lead
Inventor: SAKURAI KAZUNORI
IPC: H01L21/66
Filed: 1989-09-19
Abstract: PURPOSE:To improve the yield of production and reduce production cost by bonding a semiconductor element only with a good quality carrier tape, neglecting a poor quality of carrier tape in the next process and then manufacturing the good carrier tape alone. CONSTITUTION:An inner lead bonder takes in an image where an alignment mark is turned into a binary value by a position detection camera 4, calculates the area of a round hole 17a and determines the gravity coordinate of the round hole. Then, an attempt is made to calculate the deviation against a gravity coordinate 21 of the round hole predetermined so that an electrode 20 of a semiconductor 19 may be aligned with an inner lead 18 of a carrier tape 11 and then align the inner lead with the electrode of the semiconductor so as to carry out bonding. The carrier tape with the expanded round hole marked with an alignment mark determined as defective by a detection means results to be larger compared with the area of the round hole marked with an alignment mark formed on a nondefective carrier tape. Therefore, it is possible to bond a semiconductor element only with a nondefective carrier tape by providing a boundary value to the area of the round hole and storing the value.

Title: Magnetic sensor
Inventor: KUBO SHOICHI
IPC: G01R33/09
Filed: 1984-11-16
Abstract: PURPOSE:To prevent cracking of a magnetic sensor element substrate due to temperature difference, by bonding a bias magnet on a plastic holder and then, a magnetic sensor element thereon. CONSTITUTION:A magnetic sensor 8 is connected onto a bias magnet 11 with an adhesive 13 as linked to a plastic holder 12 in such a manner that a space 14 exists between the sensor and the plastic holder 12. As the magnetic sensor 8 is bonded only on the bias magnet 11, no stress works on the magnetic sensor element 8 due to the difference in the coefficient of thermal expansion between the plastic holder 12 and the bias magnet 11. Thus, cracking can be checked.
