Title: Manufacture of semiconductor device
Inventor: MORICHIKA YOSHIMITSU
IPC: H01L23/52
Filed: 1987-04-07
Abstract: PURPOSE:To enhance a yield rate and the reliability by executing a process to make a thickness of an interlayer insulating film on a protrusion thinner than the thickness of the interlayer insulating film in a part not containing the protrusion and another process to form an upper-layer wiring part after an opening has been made at the interlayer insulating film which has been made thin and which is situated on the protrusion. CONSTITUTION:After a diffusion layer 2 has been formed on a substrate 1, an opening which is used to connect an insulating film 3 to a lower-layer wiring part is made on the diffusion layer 2. An oxide film 4 is applied to the whole surface; a mask 5 composed of a photoresist is formed on the oxide film. Then, the oxide film 4 is etched by using the mask 5; a protrusion 4A composed of the oxide film is formed; an aluminum film is formed on the whole surface; after that, a first-layer Al wiring part 6 is formed. In succession, a plasma nitride film 7 is grown. Then, the interlayer insulating film 7 is flattened. As a result, a thickness of the interlayer insulating film 7 at a part where the protrusion 4A has been formed by the oxide film is thinner than other parts. After a fine opening 9 has been formed at this thin interlayer insulating film, a second-layer Al wiring part 8 is formed. As a result, it is possible to form a sufficient coat by using the aluminum film.

Filed: 1991-03-25
Abstract: PURPOSE:To obtain an aq. dispersion having good dispersion stability and stability with lapse of time by using a polymer having a specific polyvinyl alcohol (PVA) polymer at the side chain as the pigment dispersion stabilizer. CONSTITUTION:The polymer A having the PVA polymer 1 of >=50mol% vinyl alcohol content and 3 to 500 number average degree of polymn. at the side chain is used.

Both cases are undesirable. The content of the unit contg. the polymer 1 in the polymer A is 10 to 100wt.%. The unit exclusive of the vinyl alcohol constituting the polymer 1 may be incorporated at <50mol% into the polymer. The preferable example of the polymer A includes the homopolymer or copolymer of PVA polymer macromonomers. The above-mentioned polymer A is used at 0.01 to 100wt.% of the weight of the substance to be dispersed at the time of preparing the aq. dispersion.

Filed: 1980-06-27
Abstract: PURPOSE: To improve durability and improve permanent set resistance by quickly heating a coil material obtained by cold-coiling and cutting to above an austenitization temp. then subjecting the same to hardening and tempering.  
     CONSTITUTION: A blank wire marerial as rolled is fed continuously to a coiling machine after pickling and scalping and drawing processes for the purpose of controlling wire sizes, whereby it is cold-formed to a coil of a desired-barrel shape; thereafter it is cut and a coil material is obtained. This coil material is quickly heated by direct electric conduction such as gripping both terminals thereof with clamp type electrodes or the like. When the entire section of the wire material attains a temp. above its austenitizatin temp., for example, 900W1,000°C, the electric conduction is stopped, whereby it is hardened. Thence, it is tempered at ordinary tempering temps. in an electric furnace, after which it is subjected to post treatments such as shot peening, whereby the barrel-shaped coil spring is obtained.

Abstract: PURPOSE:To make the pressure applied to a developing device constant by partially overlapping the other ends of two bar members by a driving lever and providing an expandable bar structure connected with a spring material. CONSTITUTION:A link mechanism 31 is composed of a rocking bar 32 which separates the developing device 15 from a photosensitive drum 14 by interlocking with the opening/closing action of an upper frame 11 with respect to a lower frame 12 and presses the developing unit 15 against the photosensitive drum 14 at a prescribed interval, and the driving bar 33. As the driving bar 33 in the mechanism 31, the other ends of the two bar members 33a and 33b are partially overlapped with each other and connected expandably with a spring material such as a coil spring 34. Consequently, the expandable and elastic action of the spring material can absorb accuracy irregularity in working link mechanism parts such as the rocking bar 32 and the driving bar 33, a change in the moving amount of the link mechanism 31 when the upper frame is closed due to the eccentricity, etc., of a gap roller 15a, and a change in force that presses the developing unit 15 against the photosensitive drum 14. Thus, the pressing force applied to the developing device 15 is kept constant all the time.

Abstract: PURPOSE:To manufacture of thin sheets having uniform thickness with good efficiency by eliminating the needs to regulate the thickness of moldings when extruded by using a specific shape of the die path through which molten resin is extruded. CONSTITUTION:At the inlet side 17a of the flow path 17 for a molten resin to be extruded by an extruder, a lower tiered die portion 10 is formed on the lower part 8 of the die.

Title: Speaker equipment
Inventor: SUZUKI TATSUYA
IPC: H04R5/04
Filed: 1991-04-18
Abstract: PURPOSE:To prevent the rapid reduction in a sound pressure level at a low frequency by reproducing a signal of a frequency below a frequency of equivalent to a half wavelength being an effective distance between two speaker units sharing a high sound frequency with other speaker unit sharing a low sound frequency. CONSTITUTION:Speaker units 1, 2 have same performance and share a high sound frequency and a speaker unit 3 shares a low sound frequency. A distance difference between the distance of a sound from a speaker unit close to a front observing point of the speaker 1 or 2 to the observing point and the distance of a sound from a speaker unit remote from the observing point to the observing point and the distance is selected as an effective value which is a half wavelength. Moreover, the speakers 1, 2 are operated in an opposite phase and connected to a high sound frequency output of a dividing network 5a. The speaker 3 is connected to a low sound frequency output of the network 5a. Since the frequency below a frequency equivalent to a half wavelength of the effective distance between the high sound frequency sharing speakers 1, 2 is reproduced by the other speaker 3 sharing the low sound frequency, a rapid decrease in the low frequency sound pressure is prevented.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To inexpensively constitute an image transfer system which transfers medical image data between a terminal and an image server by the communication system of the DICO (digital imaging and communication in medicine) standard. SOLUTION: Protocol servers P1 and P2 are provided between terminals T1 to Tn, and an archiver 1 and a data base 2. When a request for desired medical image data is inputted to the terminal T1 and sent to the protocol conversion server P1, the protocol conversion server P1 sends a request for desired medical image data to the archiver 1 at the request from the terminal T1. The archiver 1 transfers the desired medical image data to the protocol conversion server P1. The protocol conversion server P1 stores the medical image data in a cache C1, converts the protocol of the DICOM standard into a general protocol such as http, and transfers the medical image data to the terminal T1. Consequently, a diagnosis can be performed on the terminal T1 by displaying the medical image data on a CRT by using a general web browser.
