Abstract: PURPOSE:To enable a vehicle to be placed in a four-wheel drive condition, by connecting either a drive side member in a fluid coupling or its driven side member to a drive shaft or a driven shaft so is to directly connect both the drive shaft and the driven shaft. CONSTITUTION:A fluid coupling 17 has a drive side member 27 connected to the side of an output shaft 20 and a driven side member 28 which is able to relatively turn to this drive side member 27 further connected to the side of a universal joint shaft 18 serving as the driven shaft. And the fluid coupling 17 fits this drive side member 27 to the first outer spline 24, formed in the drive side member 27, to be connected to the side of the output shaft 20 while connectes this driven side member 28 to the side of the universal joint shaft 18 fitting the second inner spline 30, formed in the driven side member 28, to the second outer spline 26.

Title: Lsi package
Inventor: KAMATA TOSHIYUKI
IPC: H01L21/60
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce the package sizes in the vertical and lateral directions with a wiring resistance being kept small, by providing input-output pins at the side surfaces, connecting terminals for a power supply and grounding, respectively, and forming the connecting terminals for the power supply and grounding as the substantially vertical posts. SOLUTION: A QFP package 10 has input-output pins 14 as the connecting terminals at side surfaces 12 on four sides. Furthermore, at a bottom surface 16 of the QFP package 10, connecting terminals 19 for power supplies and the grounding among the connecting terminals are provided. Therefore, the required space for at least the connecting terminals 18 for the power supplies and the grounding can be decreased. Especially, when the terminal width is made wide for setting the connecting terminal 18 for the power supply and the grounding at the low resistance, the more larger space can be decreased. For the QFP package 10, the package size can be reduced until the number of the connecting terminals can be contained at one side.

Title: Method for controlling high-frequency power unit for welding machine
Inventor: SHIMIZU IKUO
IPC: B23K9/06
Filed: 1989-05-15
Abstract: PURPOSE:To control deflected excitation even if it is generated on a transformer for a welding machine by controlling an electrification period of switching elements so that electrification is executed for a period till an absolute value of a high-frequency output current attains a prescribed set value after each of positive and negative half-waves of the above-mentioned current starts electrification. CONSTITUTION:Each absolute value of an output signal 05A or 5A corresponding to an instantaneous value of a detected 05 or 5 DC power source output current I0 or the high-frequency output current I1 is compared with a set value of a current setter 11. A signal indicating a point of time when the absolute value of the instantaneous value attains the above-mentioned set value is then sent to latch circuits 18a and 18b. Meanwhile, a reference signal of output frequency is sent to the above-mentioned latch circuits from an output frequency reference signal generator 16 and the latch circuits send signals so as to electrify switching elements 31a, 31b, 32a and 32b just for a period till a point of time when the instantaneous value of each current mentioned above attains the set value from a point of time of the start of each of positive and negative cycles of the reference signal. At the normal time when the deflected excitation is not generated, the high-frequency output current I1, namely, a welding current i2 is controlled so as to attain the prescribed set value by the current setter 11.

Title: Guide system of unmanned truck
Inventor: TERADA YOSHIYUKI
IPC: G05D1/02
Filed: 1984-06-13
Abstract: PURPOSE:To secure the smooth guidance of an unmanned truck despite a change of the guide line width by adding the weight given to the photodetecting elements which exceeds the threshold value and dividing the sum of the weight by the number of those photodetecting elements exceeding the threshold value. CONSTITUTION:A multiplexer 22 is switched properly by a selection command 29 given from a computer 25, and the output voltage sent from a phototransistor TR17 set at an end of a sensor is converted into the corresponding digital value and stored in an RAM31. The stored voltage value is smoothed with all TRs 17, and a proper threshold level is set. Then said voltage value is binary-coded based on the average value and the threshold value. The weight related to the position of each TR17 is applied to the value obtained from the binary coding operation. This product value is divided by the number of TRs 17 whose values obtained after smoothing exceeds the threshold value. Thus the center of a guide line is obtained. Based on this center line, a drive motor 3 or a steering motor 8 is driven to guide an unmanned truck.
