Title: Printed wiring board
Inventor: MAENO YUTAKA
IPC: H05K3/34
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a solder bridge, and to cope with high density packaging. SOLUTION: In a land column 4, to odd-numbered standard lands 4a, 4c, 4e, 4g and 4i, the areas of the long dimension lands 4b, 4d, 4f and 4h are large. Thus, the surface tension of solder stuck to them becomes a large and a difference is generated between the time until the solder is solidified and the time until the solder is solidified on the standard lands. Thus, since the solder is easily pulled to the long dimension lands and the solder is broken faster, the generation of the solder bridge is prevented and the high density packaging is coped with.

Abstract: PURPOSE:To prevent the shift of gears in the tooth-width directions due to thrust and enable smooth power transmission by providing properly-shaped discs with the outer diameters equal to the diameters of the pitch circles of the gears on both sides in the tooth-width directions of the gears. CONSTITUTION:A rotatable idle gear 4 is pivotally supported on a movable gear supporting arm 2, where a driven gear 8 which has the axial center fixed in position and an elastic member 7 which energizes the idle gear 4 to the driven gear 8 side via the gear supporting arm 2 are provided. On both sides in the tooth-width directions of the idle gear 4 and the driven gear 8, discs 6, 9 are fixed which have the outer diameters equal to the diameters of the pitch circles of the gears 4, 8.

Title: Manufacture of intermetallic compound al3 ti
Inventor: SUZUKI RYOSUKE
IPC: C22C1/00
Filed: 1990-08-24
Abstract: PURPOSE:To obtain the intermetallic compound of Ti and Al at high purity by pulverizing a Ti oxide and an Al oxide, executing mixing, allowing Ca to act on the above mixed powder to reduce it and thereafter removing by- products by a solvent. CONSTITUTION:In a primary stage, titanium and aluminum atoms in mixed titanium dioxide (TiO2) and aluminum oxide (Al2O3) are pulverized as fine as possible and are uniformly mixed. In a secondary stage, this oxide mixture is reduced by acting calcium or calcium hydride thereon at a high temp. in the temp. range of 1023 to 1473K (750 to 1200 deg.C). In this reducing stage, oxygen bonded with titanium and aluminum atoms is cut off by Ca, and simultaneously, the bond of Ti and Al is promoted. As a result, powdery intermetallic compound Al3Ti is synthesized together with calcium oxide and a Ca-Al allay. The CaO and Ca-Al allay by-produced in the third stage are melted away by a solvent such as water, an acid water soln. and ammonium chloride. Only the intermetallic compound Al3Ti is purely taken out.

Abstract: PURPOSE:To reduce a memory capacity required for recording sound signals by inputting compressed digital sound signals. CONSTITUTION:In the case of recording the voice of the other side, recording start signals are inputted from a control part 11 to a recording and reproducing part 10. The reproducing part 10 records encoded voice signals from the other side from a time division multiplex connection timing control part 6. When recording is completed, the completion signals are inputted from the control part 11 to the reproducing part 10, the recording of the voice signals is stopped and a normal communication state is resumed. At the time of recording the voice of its own station side, the recording start signals of the control part 11 are inputted to the reproducing part 10 and the voice signals encoded in a digital sound signal processing part 5 are recorded. The control part 11 inputs recording completion control signals to the reproducing part 10 and the recording stops. In this case, the voice of its own station side is recorded both in the communication state and a non-communication state. The voice signals recorded in the reproducing part 10 are compressed digital signals, and by compression- recording at a low bit rate the recording can be performed with less bit number, the memory capacity can be reduced and a lot of the voice can be recorded with the recording element of a same capacity.

Title: Sediment extracting device for shield machine
Inventor: KIMURA RYUICHI
IPC: E21D9/12
Filed: 1992-08-20
Abstract: PURPOSE:To prevent corotation of sediment and sticking of clayey soil by laying tow screws having an identical spiral direction of a sediment extraction device in a single casing with their blades crossing together, and by rotating them in one and the same direction with the same phase. CONSTITUTION:Each of screws 10A, 10B is composed of a shaft 11A, 11B, and a blade 12A, 12B, and the blades 12A, 12B have an identical spiral direction. The screws 10A, 10B are laid in a easing 13. The passage between the blades 12A, 12B is blocked by the blade 12B, and vice verse. Accordingly, clayey soil sticking to one blade 12A is scraped off by the other screw 12B. Sediment which is to corotate with one of the screws 10A, 10B impinges upon sediment which is to corotate with the other of the screws 10A, 10B so that the sediment cannot corotate with the screws. Then, even if slurry or air is to be jetted toward the discharge side since the intake-port pressure is high, the fluid is restricted by the blades 12A, 12B, causing a pressure drop, and accordingly, no jetting occurs on the discharge side. Further, a similar effect may be obtained in the reverse direction from the discharge port side to the intake port side.

Title: Acceleration/deceleration control method for articulated robot
Inventor: YASUI KEIJI
IPC: G05B19/4155
Filed: 1991-09-02
Abstract: PURPOSE:To perform the control in order to carry out an operating program in the shortest time without reducing the angular acceleration even with a teaching program of a short acceleration/deceleration time. CONSTITUTION:The interpolation is calculated 1 between the teaching points from the positions of teaching points and the speed set between the teaching points. The angular acceleration of each articulation decided by the calculation 1 is compared with the maximum angular acceleration set previously. If the former acceleration is higher than the latter one, the tentative acceleration/ deceleration control 2 is carried out based on the set maximum angular acceleration to calculate the acceleration/deceleration time. the calculated time is divided by the feedback control time constant for decision of a time coefficient 3. When this time coefficient is larger than 1, the control 2 is defined as the formal acceleration/deceleration control. When the time coefficient is smaller than 1, the maximum angular acceleration is calculated so as to be adversely proportional to the time coefficient for execution of the second acceleration/ deceleration control 4.

IPC: G06F13/42
Filed: 1987-09-04
Abstract: PURPOSE:To reduce the transmission delay of data as well as the load given to a relaying information processing part, by adding a data input/output terminal and a clock terminal to the master and slave information processing parts respectively and connecting these two terminals to a bidirectional serial data line and a clock signal line respectively so that data can be transferred directly between the slave information processing parts. CONSTITUTION:Then a slave information processor A transmits data to another information processing part, the transmitting part of the part A confirms whether a bidirectional serial data line is kept under a busy or non-busy state to turn the non- busy state into a busy state. Thus a clock signal transmitting circuit of a master information processing part transmits a clock signal to a clock signal line. The transmitting part of the part A sends a transmitter identification code to the bidirectional serial data line to show the transmitter synchronously with the clock signal received from the master information processing part. While a transmission control part of the part A compares the signal transmitted from the transmitting part with the signal received by the receiving part from the bidirectional serial data line. Then various control signals are sent to the transmitting part when the number of discordant bits exceeds a reference level.
