Patent JP-H0421582-A (JP)
Title: Ceramic product
Inventor: ASAYAMA MASAHIRO
IPC: C04B41/89
Filed: 1990-05-15
Abstract: PURPOSE:To obtain a complex type ceramic product, having improved strength, by laying a specific intermediate film between the surface of a substrate comprising a silicon nitride sintered material and a surface film composed of silicon nitride formed on the surface. CONSTITUTION:This ceramic product has a complex structure prepared by directly forming an intermediate film 2 between the surface of a substrate 1 comprising a silicon nitride sintered material and then making a surface film 3 composed of silicon nitride on the surface of the intermediate film 2 in a superimposed way. The intermediate film 2 can be formed from various ceramics as a raw material as long as the ceramic has a coefficient of thermal expansion between a coefficient of thermal expansion of the substrate 1 and a coefficient of thermal expansion of the surface film 3. Above all, the intermediate film is preferably formed by using silicon nitride, the ceramic constituting the substrate 1, as a raw material. The intermediate film 2 and the surface film 3 are made by CVD (chemical vapor deposition) or PVD (physical vapor deposition).

Title: Slow cooling material for steel and its production
Inventor: GOTO MASAHIRO
IPC: B09B3/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To produce a slow cooling material for steel having good quality, by using a raw material obtainable in a low cost. SOLUTION: This material is composed of the granular material of a composition containing at least a carbon raw material (a) (e.g. a carbon composition recovered as heavy oil combustion ash or a carbon composition recovered from the heavy oil combustion ash) and a coal ash (b). Such slow cooling material for steel is produced by applying rolling-granulation to the composition containing the carbon composition (a), e.g. the one recovered from a wet-type treating process of the heavy oil combustion ash including a process for making the heavy oil combustion ash to slurry state and a process for separating the obtd. slurry into the solid and liquid, the coal ash (b), clay (c), cement (d) and clay and lime (e).

Title: Magnetic recording and reproducing device
Inventor: IDEI TOSHIO
IPC: H04N5/7826
Filed: 1983-07-05
Abstract: PURPOSE:To obtain an accurate reproduction scan locus by adding a control system to a tracking controller of 4-frequency pilot system in order to correct automatically the frequency variation of a pilot signal. CONSTITUTION:The output signals of the 1st and 2nd BPF23 and 24 are limited by the 1st and 2nd amplitude controllers 33 and 34 respectively, and the frequency variations of these output signals are detected by the 1st and 2nd FM wave detectors 35 and 36 respectively. Then these detection outputs are added together by an adder 37. Thus a tracking error signal of the scan direction of a video track is obtained independently of the tracking variation vertical to the scan direction of the video track. A time axis error signal thus obtained in the scan direction of the video track is amplified by the 2nd drive amplifier 38, and the output of the amplifier 38 is applied to the 2nd mobile actuator 39. Thus a reproduction head is shifted in the scan direction.

Filed: 1991-04-26
Abstract: PURPOSE:To obtain optical parts excellent in transparency, heat resistance, surface hardness, water absorption, optical anisotropy, formability, and massproductivity by using wholly fluorinated polyimide expressed by specified formula as the main structural component. CONSTITUTION:A fluorinated polyimide containing a repeating unit expressed by formula is used as the main structural component. In formula, R1 and R2 consist of 1-3 benzene rings, and if 2 or more rings are included, rings are indirectly coupled in R1 and directly or indirectly coupled in R2. All hydrogen in this polyimide is replaced with fluorine or perfluoroalkyl groups.

Title: Ion implanting device
Inventor: HATTORI MASAFUMI
IPC: H01J37/317
Filed: 1994-05-12
Abstract: PURPOSE:To prevent an error or beam current measurement even if insulating performance of insulators for insulating a center suppressor electrode is deteriorated by switching the center suppressor electrode to a side of a center Faraday cylinder when an ion beam is radiated on a base board on a holder so as to implant an ion. CONSTITUTION:When a beam current of an ion beam 2 is measured by using a center Faraday cylinder 22, a negative voltage is applied to a center suppressor electrode 20 from a suppressor power source 26 so that an original function of the electrode 20, i.e., a function of restricting secondary electron emission from the center Faraday cylinder 22 can be exhibited since the electrode 20 is switched on a side of the power source 26. Meanwhile, when an ion is implanted by radiating the ion beam 2 to a base board 6 on a holder 8, no voltage is applied to the electrode 20 from the power source 26 since the electrode 20 is switched on a side of the Faraday cylinder 22. Consequently, no leak current flows in a beam current measuring device 24 via insulators 18, 16 from the power source 26 even if insulating performance of the insulators 18, 16 for insulating the electrode 20 is deteriorated due to a stain or the like, thereby preventing generation of an error of beam current measurement by the measuring device 24 at the time of ion implantation.

Title: Ink jet head
Inventor: OKADA JIYUNICHI
IPC: B41J2/14
Filed: 1980-09-08
Abstract: PURPOSE:To prevent a dot from being displaced in position and to lengthen the distance between a nozzle and a printing paper, by a method wherein the front of a nozzle is structured such that ink drop flies on the extension line of a jet axis. CONSTITUTION:An auxiliary ring 33, having a pore 32 matching a nozzle diameter, is located in the proximity of a nozzle 24. This causes forming of an ink layer 28 into an uniform state on a nozzle jet axis, causes flying of ink particles 29 on an extension line 20 of the nozzle jet axis, and almost prevents a dot from being displaced in position. An auxiliary plate of t1 t2 can be used, or anozzle part of a head base plate 21 can also be cut into t1 t2 to obtain the same effect. An another method is such that a flat base plate 5 projects by a full length t3 from the head base plate 21, which results in forming an ink layer 28 into an uniform state on the nozzle jet axis, causing flying of the ink particles 29 on the extension line of the jet aixs, and almost preventing a dot from being displaced in position. By preventing the dot from being displaced in position, the lengthening of a distance between a nozzle and a printing paper can be realized.
