Title: Cast-forming of silicon nitride powder
Inventor: TSUTO HIROYUKI
IPC: C04B35/58
Filed: 1992-09-22
Abstract: PURPOSE:To provide a process for the cast-forming of a silicon nitride powder such as silicon nitride and Sialon. CONSTITUTION:Silicon nitride powder coated with a water-resistant polyamide resin is dispersed in water and the obtained slurry is subjected to cast-forming. The coating with the polyamide resin can be carried out by coating the surface of the silicon nitride powder particle with a dibasic acid or its derivative, dispersing the coated particles in a solution of a diamine or a diamine derivative and polymerizing the components. The surface-oxidation of the silicon nitride powder caused by the mixing of the powder with water in the preparation of a cast-forming slurry can be prevented even by using water as the dispersion medium of the cast-forming slurry and, accordingly, a sintered silicon nitride having excellent mechanical strength can be produced without deteriorating the intrinsic characteristic properties of the silicon nitride.

Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To attain stable and efficient servo detection by compensating a missing pulse generated in a gray code area for recording track information in a servo area of a hard disk drive. SOLUTION: A 1st AND gate 426 detects a positive pulse gray code by executing the AND operation of signals inputted from a digital servo data generator 418, a positive pulse detection window generator 420 and a gray code detection window generator 424 and outputs detected gray code to a positive gray synchronization/data separating circuit 430. Respective positive gray synchronization/data separating circuits 430, 432 mutually separate gray data and gray synchronization, which are processed by OR operation through respective OR gates 434, 436 and respective OR results are inputted to a gray synchronization judging circuit 438 and a gray data judging circuit 440. Even when an error is generated in either one of positive and negative gray data, the circuit 440 restores the error and transmits the restored data to a CPU 442.

Title: Object video image coder and object video image coding/ decoding system
Inventor: UEHARA KENSUKE
IPC: H04N19/50
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent jitters caused on a borderline, with which object video images are in contact when the frame rates of the object video images differ from each other. SOLUTION: A duplicate area detection section 158 detects a duplicate area 200 from contour data A108, B116, resulting from extracting areas of the object video images. However, by applying the contour data A108, B116 to a motion detection section 8, a motion of a borderline 2 of the duplicate area 200 is detected, and a duplicate area correction section 12 reserves a concealed area with a margin from the borderline 2 of the lower object video images, detected by the duplicate area detection section 158 toward the rear side of the video images, on the basis of the result of detection. Cutting the object video image by the borderline moved newly prevents the occurrence of jitters caused on the borderline 2.

Title: Recording apparatus
Inventor: TSUZUKI TOSHIHIRO
IPC: B41J11/42
Filed: 1989-10-25
Abstract: PURPOSE:To perform good recording free from irregularity by making the change-over of the exciting phase of a stepping motor synchronous to a recording related signal and setting the feed quantity of a recording medium of a feed means based on one change-over of the exciting phase of the stepping motor to an integral fraction of the interval of recording lines. CONSTITUTION:An exciting phase change-over synchronizing means is constituted of a part changing over the exciting phase of a stepping motor 52 on the basis of the horizontal synchronous signals of a CPU 92 and an ROM 94 and both of the change-over of the exciting phase of the stepping motor 52 and exposure are performed in synchronous relation to the generation of the horizontal synchronous signals and the feed quantity of a photosensitive drum 48 due to one change-over of the exciting phase is set to an integral fraction of an exposure line interval. Therefore, the rotational speed of the stepping motor 52 at the time when the horizontal synchronous signals are emitted becomes same every time and the speed irregularity at every exposure line appears in the same way. By this constitution, the exposure line interval of the photosensitive drum 48 becomes constant and printing of good quality is obtained.

Title: Plane spiral inductor and its manufacture
Inventor: WADA SHINICHI
IPC: H01L23/522
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a plane spiral inductor which can realize reduction of size without generating deterioration of resolution or increase of wiring resistance in a photolithography process. SOLUTION: The intersection part of a wiring 13 of a first layer and a wiring 15 of a second layer is in the inside of a recessed part 23 formed on an insulating film on a semiconductor substrate. Thereby the film thickness of a resist pattern turning to a mask of gold plating constituting the wiring 15 does not become thinner than other parts in the intersection part. Even if the gold plating is grown as far as the film thickness nearly equal to the resist pattern, the gold plating dose not protrude to the upper part of the resist pattern and grow in the side direction, and shortcircutting between wirings is not generated. Thereby it is made unnecessary that the wiring 15 of a second layer is thinned and the space between the wirings 15 is increased, and the size of an element can be reduced without increasing the loss due to wiring resistance.  Since it is unnecessary that the film of the resist pattern is made thicker than the conventional case, resolution in a photolithography process is not deteriorated.
