Title: Forging method for forging part having reverse tapered part
Inventor: TAKAHARA TAKESHI
IPC: B21K1/00
Filed: 1987-10-30
Abstract: PURPOSE:To form a reverse tapered part without the need for cutting by forming the reverse tapered part by strongly pressing by a punching die the projecting part having the excess metal part of a rough forging part and cold-forging this excess metal part, making it as a finished forging part and rapping it from the reverse tapered die face. CONSTITUTION:The rough forging part 5 having a main body 9, non-reverse tapering projecting part 11 and partially projecting excess metal part 13 is obtd. by rough- forging a metal blank by using a rough forging die. At finish forging stage the projection part 11 having the excess metal part 13 of the rough forging part 5 is strongly pressed by punching dies 57, 61 to the main cavity die face 53 of a finish forging die 21. The excess metal part 13 of the rough forging part 5 is deformed by flowing in the reverse taper die face 55 direction and a finished forging part 25 is obtd. At rapping stage a knockout pin is extruded in parallel to a shaft core in the state of separating a punching die 23 from the finished forging part 25, which is rapped from the reverse tapered die face 53 of the finish forging die 21. The reverse tapered part is thus formed without cutting and the strength of the reverse tapered part of the projection part is also improved.

IPC: H01L21/822
Filed: 1985-12-09
Abstract: PURPOSE:To avoid the lowering of dielectric strength at the corner parts of a groove for forming a groove digging type capacitor and avoid difficulty of filling the groove effectively by a method wherein the shoulder parts and the corner parts of the bottom of the groove after a grooving process are chamfered. CONSTITUTION:Oxidation resistant films 4 are formed over the surface of the active region and on the whole side surfaces of a groove 3 except the bottom of a semiconductor substrate 1, for instance by CVD, and, by utilizing the oxidation resistant films 4 as a mask, an oxidation treatment is carried out to make a thick oxide film 5 grow to the extent of creating bird's beaks over the bottom and bottom corners 3b and shoulder parts 3a of the groove 3. These oxided resistant films 4 and the thick oxide film 5 are removed, for instance by wet etching. With this constitution, the shoulder parts 3a and the bottom corner parts 3b are chamfered and formed into round arc surfaces 3c and 3d so that electric field concentration at the edge parts can be eliminated and dielectric strength can be improved and it can be made easy to fill the groove in the next process when a gate insulating film is formed.

Title: Low voltage transformer linear circuit
Inventor: KUSAKABE HIROMI
IPC: H03F3/45
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To enable low-voltage operation and to provide satisfactory extensibility by turning (n) pieces of differential couples composed of bipolar transistors having specified polarities and the electrodes of respectively correspondent feedback transistors into specified connecting state. SOLUTION: This circuit is composed of two kinds of blocks, i.e., common block from a 1st block to (n-1)th block and n-th final block. This common block can be arbitrarily extended. A transformer linear loop is composed of VBE of transistors Q1, Q2, Q3,..., Q2n consisting of 1st to n-th differential couples. Transistors QA1, QA2,..., QAn are current source transistors for supplying bias currents to the correspondent differential couples. Then, these transistors are connected to respective base electrodes so as to constitute a negative feedback from the collector electrodes of transistors consisting of differential couples. Thus, low-voltage operation at about 1 V is enabled and extension is easily enabled by the simple repetition of the same block.

Abstract: PURPOSE:To constitute a compact moving carriage of an image scanner by inserting at least one mirror between an image forming lens and the image scanner. CONSTITUTION:In a moving carriage 8 consisting of a light source 1, a first mirror 21, an image forming lens 3, and an image sensor 4 in the scanner where mirrors 22 to 25 are fixed to the scanner main body, an image-side mirror 9 is arranged between the image forming lens 3 and the image sensor 4.

Since the image sensor 4 and the sensor substrate are placed in parallel with the exit optical path from the moving carriage 8 and the incidence optical path to the moving carriage, the thickness in the vertical direction of the moving carriage 8 is reduced independently of the size of, the sensor substrate, and the scanner main body is made thin, and the overall length of the scanner main body is reduced.

Title: System for processing digital coding signal
Inventor: WILKINSON JAMES HEDLEY
IPC: G11B27/031
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain a system for processing a digital coding signal without data loss by editing and without deteriorating quality of picture. SOLUTION: An MPEG 2 coding signal which includes an intracoded frame I and an intercoded frame B is decoded into a baseband (70 to 74) and this is reencoded into the I-frame (76). The quantization level QV and the motion vector of the B-frame are kept invariable and maintained connecting with the corresponding frame reencoded as I-frame. Thus, the I-frame is decoded into a baseband, processed and reencoded into an I-frame without causing deterioration. Then, the I-frame is reencoded into, for example, an I- or a B-frame, but deterioration at this time is extremely small.
