Title: Clock signal generator
Inventor: MINAMIGUCHI HIDENORI
IPC: H03K5/156
Filed: 1987-03-27
Abstract: PURPOSE:To make the upper limit of the frequency of an output clock signal of a flip-flop the same as the frequency of the master clock signal by using a change point pulse of the master clock signal as the clock for a counter and the flip-flop. CONSTITUTION:A change point pulse signal generating means 10 generates a pulse signal representing a change in the leading/trailing of the master clock signal. A counter 12 counts the change point pulse signal and outputs the count. A clock signal generating pattern is written in advance in the ROM 14 corresponding to each address and said count is used as the address input to the ROM 14 and the clock signal pattern corresponding thereto is outputted from the ROM 14 and fed to a flip-flop circuit 16. Since the circuit 16 is operated by a change point pulse signal by the means 10, a clock signal output is obtained from the circuit 16 at every change point of the master clock signal. Thus, the clock signal having a frequency equal to the frequency of the maximum master clock signal is obtained.

Title: Welding robot
Inventor: BABA TSUTOMU
IPC: B23K9/12
Filed: 1979-06-13
Abstract: PURPOSE: To make possible simultaneous welding of approximately parallel two horizontal fillet weldings by mounting torches to the specific mounting materials provided to the torch mounting means which is movable in the three-dimensional directions and mounting tracing contactors to the torches or mounting materials above the torches.  
     CONSTITUTION: A torch mounting means 8 is movable in mutually orthogonal vertical and 2 horizontal directions and performs automatic welding by controlling the relative positions with the work mounting means. A pair of mounting materials 14, 14' fitted to the rail extending in the Y direction of the mounting means 8 are first fully detached by their hooking and detaching mechanism 15. Thence, the work W of a long length is aligned of its lengthwise direction approximately in the X direction and is fixed, after which the mounting means 8 is moved so that the wire ends of torches 19, 19' come to above the plate W 2 . Next, the mechanism 15 is moved to the alternate long and two short dashes line position, where the detaching action is released and the mounting materials are hooked by springs 16, causing tracing contactors 20, 20' make contact with the plates W 3 , W 3 ' and stop. Further, the wire ends are aligned to the approximately parallel weld lines WL, WL', whereby the simultaneous welding is accomplished.

Title: Mos gate semiconductor device
Inventor: NEILSON JOHN MANNING
IPC: H01L21/331
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To increase accuracy in one dopant introducing step by forming a third doped region so as to surround a second doped region excluding the second intercept formed part of a substrate surface of a second region, in a first doped region. SOLUTION: A dopant is introduced into a semiconductor substrate 12, and a first doped region 28 being a drain region having a first intercept of a semiconductor surface is formed under a gate construction. Then, a second doped region 26 being a source region having a substrate surface second intercept separated from the first intercept is formed in a first region 28, in a process using a vertical wall as a dopant mask again. Furthermore, a third doped region being a P-type composite region containing a P<-> region 30 and a P<+> region 32 is formed, so as to surround the second doped region 26. Consequently, it becomes possible to make a gate control construction part smaller, and to increase accuracy in a dopant introducing step.

Abstract: PURPOSE:To detect oil leak without relating to the temperature change of the oil in a transformer by correcting the proper reference level of the oil in an adjuster with the expansion or the contraction of the adjusting oil in an adjusting oil tank. CONSTITUTION:Oil level is displayed by the rise and the fall of a float 9. An adjusting oil 37 filled in an adjusting tank 36 expands or contracts in accordance with the temperature change inside a transformer. The quantity of volume change of the oil is brought to a cylinder 25 through a pipe 28 and pushes up or down a piston 26 inserted in the cylinder 25. This corrects the proper reference level of the oil. The movements of the float 9 and the piston 26 are adjusted by adjusting the quantity of the adjusting oil 37 in the tank 36. If the coil leaks, a lead switch 39 is opened by the magnetic force of a magnet 7 installed inside the float 9. In accordance with the switch, a signal is sent outward through a lead wire 40 and a terminal strip 18.

Filed: 1986-04-04
Abstract: PURPOSE:To facilitate the improvement in a positioning accuracy by composing the elastic vibration of a component member due to the driving reaction force of an actuator so as to limit only to the member having less effect on the positioning accuracy. CONSTITUTION:An actuator 4 and actuator assembly body 8 are subjected to a bolt fastening so as to insert a magnetic head into the opening part 11 for fitting the actuator provided on a base 1. The base 1, spindle 3 and actuator 8 are close to an integral rigid body and no relative displacement is caused with the elastic deformation for the exciting force applied from the external part. The magnetic circuit 5 for driving is fitted to the supporting member 6 serving as well for sealing with the external part and fixed to the base 1 via the supporting member 6. The elastic deformation is therefore caused on the supporting member 6 only even with the reaction force being caused and no positioning error is caused because the base 1, spindle 3 and actuator 8 move integrally.
