Title: Ink jet recording head
Inventor: TAKADA YOSHIHIRO
IPC: B41J2/05
Filed: 1986-08-11
Abstract: PURPOSE:To control the quantity of a liquid jetted through each nozzle and make it possible to record gradations, by providing each nozzle with an electro-thermal converter the film thickness of which is increasingly larger toward a central part symmetrically from the left and right sides of the converter with the center line perpendicular to a current-passing direction. CONSTITUTION:An electro-thermal converter 30 has a film thickness d' of an electro- thermal converter layer set to be greatest at a central part and continuously reduced from the central part toward both end parts symmetrically on the left and right sides. When a pulsed current is applied to the electro-thermal converter 30 from a driving pulse power source, an upper layer of the converter 30 has a temperature distribution in which the temperature is highest at a central part and is continuously lowered toward end parts, due to the relationship between the effects of heat conduction to a heat-accumulating layer provided as a lower layer and to an ink provided at the upper layer and the temperature distribution. Therefore, when the current-passing time or pulse voltage of driving pulses supplied to the converter 30 is varied, the thermal output of the converter 30 can be regulated to vary that region on the surface of the converter which is heated to a bubble formation starting temperature of the ink. Accordingly, the volume of an ink droplet ejected can be varied gradually and largely.

Title: Removing method of phosphorus component
Inventor: MATSUBARA KAZUHIRO
IPC: B01D53/46
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To simply and effectively recover hydrochloric acid containing no phosphorus component from a hydrogen chloride gas generated in a process of dehydrogen-chloride condensation reaction of a phosphorus chloride compound with an active hydrogen- containing organic compound by introducing the hydrogen chloride gas into an absorption vessel housing a saturated aq. hydrochloric acid. SOLUTION: The hydrogen chloride gas generated in the process of dehydrogen- chloride condensation reaction of the phosphorus chloride compound and the organic compound having an active hydrogen is introduced into the absorption vessel housing the saturated aq. hydrochoric acid and the entrained phosphorus chloride compound is hydrolyzed and collected in the absorption vessel as a phosphate compound. Since phosphorus trichloride, phosphorus pentachloride and phosphorus oxychloride in the phosphorus chloride compounds have high vapor pressure and are entrained in large quantity with the generated hydrogen chloride, the remarkable effect is attained.  Since a compound having phenolic hydroxide groups in compounds having the active hydrogen hardly reacts compared to another compounds and rather higher reaction temp. is required, the entrained quantity of the phosphorus chloride compound is increased and then, remarkable effect is attained.

Abstract: PURPOSE:To obtain many gradations with a small number of time divisions by setting the confronting electric field of a ferroelectric material film intenser than that of a ferroelectric liquid crystal layer, and applying plural frames of a multiplex driving waveform as one selection period to a scanning electrode. CONSTITUTION:The value of the confronting electric field 201 of the liquid crystal layer is set lower than that of the confronting electric field 202 of the ferroelectric dielectric film to obtain three selection conditions of an electric field 203 which is inverted by neither the liquid crystal layer nor ferroelectric material film, an electric field 204 which is inverted by the liquid crystal layer, and an electric field 205 which is inverted by the both. Further, when an electric field 206 is applied, the liquid crystal layer and ferroelectric material layer are inverted and set in the same direction, so it is applied as a refresh signal before a selection signal to enable dynamic driving.

Title: Bonding method of semiconductor device
Inventor: TANAKA RYUKICHI
IPC: H01L21/60
Filed: 1989-07-25
Abstract: PURPOSE:To prevent the generation of cracks and cutting off when a finger lead is sufficiently bent, by moving a thermocompression bonding head and a bonding stand relatively downward with respect to a carrier tape, while heat inertia at the time of thermocompression bonding of the finger lead and a bump electrode is present. CONSTITUTION:A finger lead 18 composed of copper or copper ally on a carrier tape 16 is bonded to a bump electrode 14 on an IC chip 2 mounted on a bonding stand 11, by themocompression bonding, with a thermocompression bonding head 19. While the heat inertia at the time of thermocompression bonding is present, the thermocompression bonding head 19 and the bonding stand 11 are moved relatively downward with respect to the carrier tape, thereby bending the finger lead 18. Since the finger lead is bent in the state that the heat inertia at the time of thermocompression bonding is present, the finger lead is easy to stretch as compared with the case of normal temperature. As a result, when the elongation percentage of the finger lead exceeds the limit in the case of normal temperature, cracks and cutting off are hard to generate, and therefore reliability and productivity can be improved.

Abstract: PURPOSE:To enable thermal transfer recording in continuous gradation mode by providing a thermal transfer recording layer applied with coating liquid prepared through melting and blending using mutually non-soluble organic resistant colors having varying thermal transfer initiation temperatures on a heat- resistant base film. CONSTITUTION:A coating liquid is prepared by blending and solving mutually non-soluble organic resins, one having a low thermal transfer initiation temperature and the other a high thermal transfer initiation temperature, with colors, in a solvent. This liquid is applied to the surface of a heat-resistant base film to provide a thermal transfer recording layer. Thus the thermal transfer recording sheet is formed. It is recommended that for better performance the melting point or softening point of high-temperature resin be more than 10 degrees higher than that of low-temperature resin. The colors used are ordinary pigments for printing or as paint or dyes. However, a mixture of pigment and dye is preferred from a viewpoint of continuous gradation characteristics. The best choice is inorganic pigments such as carbon black or red ocher.
