Title: Ink jet head, its production, and ink jet apparatus equipped with ink jet head
Inventor: MIYAKOSHI TOSHIMORI
IPC: B41J2/05
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To make it hard to receive the effect of the shift of meshes at the time of formation of respective layers and to enable excellent energy conservation/emission stabilization by providing an area where a protective film is locally thin inside the connection parts of heating resistors and wirings and providing recessed parts between the heating resistors and bringing flow passage walls into contact with a substrate through the bottom surface thereof. SOLUTION: An area 107 where a protective film is locally thin is provided in a substrate 104 inside the connection parts of heating resistors 105 and electrode wirings 106 and recesses equipped with the bottom surfaces for the contact with flow passage walls 108 are formed between the heating resistors 105 so as to be positioned below a heat acting surface. A first protective film 107A and a second protective film 107B are formed simultaneously when only one layer of a two-layered protective film is removed by patterning. By this constitution, the effect of the shift of meshes, over-etching and step coverage at the time of formation of respective layers is made hard to receive and the recesses can be formed precisely and power consumption can be reduced and good emission stability is enabled.

Inventor: FUJIWARA ICHIRO
IPC: H01L29/792
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To reduce the operating voltage value of a memory cell of MONOS type, etc., to a value not larger than 10 V, while keeping intact its well disturbance characteristic and its high-speed writing characteristic. SOLUTION: In a memory transistor (M11, etc.), a gate electrode and gate insulation films, including a tunnel insulation film, are laminated on the semiconductor-channel forming region provided on the surface of a substrate to provide discretely in the form of a plane charge storing means in the gate insulation film. The memory transistor has, above the gate electrode or a wiring layer connected with the gate electrode (e.g. word line WL1, etc.), a pull-up electrode closing thereto via a dielectric film. The pull-up electrode is connected with a pull-up gate biasing circuit 102 for applying a predetermined voltage to the pull-up electrode. The pull-up gate biasing circuit 102 feeds to the pull-up electrode through a capacitive coupling, via a selective transistor ST0 a voltage tending to boost the gate electrode (the word line WL1, etc.).

Title: Information recording method
Inventor: SUZUKI KATSUMI
IPC: G11B7/30
Filed: 1989-11-30
Abstract: PURPOSE:To hold a playback signal at high level by scanning a recording layer at least once with a light beam whose scanning speed and/or power is so adjusted that the recording layer is fused to uniformalize its constituent elements. CONSTITUTION:For single laser beam overwriting, the recording layer is irradiated with the laser beam obtained by superposing a pulse with higher recording power than erasure power upon the erasure power and while amorphous recording marks are erased, recording marks corresponding to new information is formed. In this case, when the frequency of repetition of recording, erasure, or overwriting reaches a specific frequency, the recording layer is scanned at least once with the light beam whose scanning speed and/or power is so adjusted that the elements constituting the recording layer are uniformalized by fusing the recording layer. Consequently, the recording parts and nonrecording parts of the recording layer are both fused to uniformalize the constituent elements, thereby evading the thinning of recording marks. Thereby, the playback signal can be held at a sufficient value.

IPC: B41J2/05
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for an ink jet printer head exhibiting excellent workability in which an ejection opening can be shaped correctly and easily. SOLUTION: A barrier wall material 31' and a thermoplastic polyimide adhesive layer 38 are applied sequentially onto the entire upper surface of a chip substrate 20 and then a metal film is sputtered thereon and etched to obtain a metal mask 39 for forming a barrier wall. The two layer structure of the barrier wall material 31' and the adhesive layer 38 is then dry etched along the metal mask 39 and a removing port 32 is removed to form a barrier wall 31 (31-1, 31-2, 31-3). Subsequently, a residual metal mask 39 is removed to expose the adhesive layer 38 on the barrier wall 31, an orifice plate 33 is attached thereto and a pattern 42 for forming ejection nozzles through the metal mask 35 is formed thereon before forming ejection nozzles 36 by helicon wave etching.  Since the adhesive layer 38 is not present at parts for boring the ejection nozzles, excess adhesive is prevented from causing troubles, e.g. unstable shaping of ejection opening or generation of residues, after etching.

Title: Wavelength multiple communication optical demultiplexing device
Inventor: OTANI TOMOHIRO
IPC: H04B10/2519
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To reduce efficiently distributed compensation, loss compensation and an active device such as an optical amplifier, etc. SOLUTION: For a demultiplexer 19, couplers 20 to 22 are arranged in many stages. Optical filters 15 to 17 are connected to one branch of the couplers. Also, equalization fibers 23 to 25 are inserted between the other branch of the couplers 20 to 22 and a couple on the next stage. An optical fiber 18 for the shortest wavelength is connected to the fiber 25 on the last stage. Consequently, because the fibers 23 to 25 are serially connected, they cumulatively perform distributed compensating action. Thus, they reduce the amount of equalization filters as a whole. As a result, because attenuation quantity is also reduced, the number of optical amplifiers is also reduced.

Title: Method of heat-insulation construction of concrete surface for inhibiting temperature change near concrete surface
Inventor: KURIHARA TETSUO
IPC: E01D19/02
Filed: 1987-12-10
Abstract: PURPOSE: To reduce a temperature difference on a surface and prevent the occurrence of cracking by placing and curing concrete after spraying material of low heat conductivity all over the outside of a form, and spraying material of low heat conductivity on the surface right after the removal of the form. CONSTITUTION: After a heat insulating material such as a hard urethane of extremely low heat conductivity is sprayed all over the outside of a metal framed form 1 and layered thereon at a thickness of 2 cm or more, concrete 3 is placed. After it is cured, the form is removed and a heat insulating material 4 such as a hard urethane foam of extremely low heat conductivity is immediately sprayed all over a concrete surface at a thickness of 2 cm or more. In this way, a change in volume possibly caused by different temperature changes on respective parts of the concrete right after the placement of mass concrete and after the removal of the form constrains free deformation to thereby constrain the tensile strength of the concrete, so that tensile stress over the tensile strength of the concrete may be developed to prevent the occurrence of cracking.
