Title: Ink recorder
Inventor: TAMURA SAKAE
IPC: B41J2/325
Filed: 1989-02-10
Abstract: PURPOSE:To enable stable ink feed to be performed with high reliability of ink feed to an ink holding part by a method wherein a heating resistor film is used for a heating resistor layer, an ink holding film having through holes for holding ink is used for an ink holding layer, and those two sheets of films are piled with each other at a recording part. CONSTITUTION:After forming an ink holding film 7 by perforating a plurality of through holes 24 for holding ink in a thickness direction of the film, an about 0.2mum thickness water-repellent hydrogen-containing amorphous silicon film is obtained by leaving the through holes 24 as they are on a side surface of the ink holding film 7 by using a plasma CVD reaction. A heating resistor film 1 consisting of total aromatic polyimide and conductive carbon is laid on a surface opposed to a surface on which a water repellent layer of the ink holding film 7 is formed, and a needle electrode 3 and a return electrode 33 are brought in sliding contact with the heating resistor film 1 at the superposed part.

Title: Method for brazing semiconductor substrate onto support
Inventor: HERUMUUTO SHIYUTORATSUKU
IPC: H01L23/482
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to significantly reduce the thickness of a nickel layer without completely melting the nickel layer in brazing material by adding to the brazing material a nickel content equivalent to the solubility of nickel in the brazing material at an ordinary brazing temperature. SOLUTION: An aluminum layer 3, a titanium layer 4, a nickel layer 5 and a silver layer 6 are formed on the underside of a silicon semiconductor substrate 1 in this order. Brazing material 7 placed between a support 2 and the silver layer 6 is fused to melt the silver layer 6 during a brazing process. If tin is used for brazing material 7, approx. 1% of nickel is added to the brazing material 7. As a result, the nickel layer 5 is melted only slightly. This is because only approx. 1% of nickel is melted by tin at ordinary brazing temperature (250 deg.C-400 deg.C) and because the tin has been already saturated by the nickel additive. As a result, the nickel layer is not completely melted in the brazing material and it is possible to make the thickness of the nickel layer vary thin.

Title: Step motor
Inventor: NISHIMURA MAKOTO
IPC: H02P8/24
Filed: 1984-02-20
Abstract: PURPOSE:To sufficiently shorten the positioning time by shortcircuiting a brake winding at the stopping time, thereby abruptly stopping the rotation. CONSTITUTION:Before the finally excited winding is excited in case of stopping the rotation of the shaft 5 of a step motor 4, windings 27, 28 are shortcircuited. Thus, electromotive forces for stopping the vibration of the rotor 17 of the motor 4 are generated in the windings 27, 28. Thus, the vibration of the shaft 5 at the rotation stopping time can be attenuated, the shaft 5 is abruptly stopped. In other words, a magnetic head coupled with the shaft 5 can be set on the predetermined recording track in a short time without an overshoot.

Title: Measuring apparatus for fine particle in liquid
Inventor: WAKAMURA HITOSHI
IPC: G01N15/02
Filed: 1989-02-13
Abstract: PURPOSE:To put a measurement under optimum conditions by a method wherein a laser projector and a photo detector are arranged and a liquid containing fine particles flows in the same direction as that of receiving light so that a flow of the liquid is made almost a laminar flow to stabilize a direction of fine particles pass. CONSTITUTION:A laser luminous flux 3 enters an incoming window 4 of a measuring cell 1 to be condensed to a condensing point 34 in a measuring area. On the other hand, a sample liquid flows into a cylinder section 33 through an inflow tube 30 for letting a liquid containing fine particles flow in and through a double cylinder tube 32 to be mixed evenly. A change in sectional areas of the double cylinder section 32 and the cylinder section 33 is reduced so that the liquid is prevented from making a disturbing flow when flowing into the cylinder section 33 to make it develop a cylindrical flow with the sectional area little changing before the measuring area. Thus, the liquid can pass through the measuring area as a stable laminar flow at a fixed velocity at the right angle to the projection of a laser light. Scattered light 6 forms an image on a mask with a light receiving lens to reach a photomultiplier tube. This is applied for a measurement of characteristic of fine particles using a photo counting method.
