Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To enable soldering with one hand by arranging a through-hole for solder in a soldering trowel body and gears on a side surface of the through-hole for solder through supporting shafts. SOLUTION: The through-hole 2 for solder is arranged in the soldering trowel 1 extending a handle to the tip part 8 of the trowel. The gear 5 through the supporting shaft 4 and the gear 6 through the supporting shaft 3, are arranged on the side surface of the through-hole 2 of the solder. Then, the gap between the gears 5, 6 is opened in such degree that the surface of the solder is squeezed with the gears 5, 6. In the case of using this trowel, at the time of inserting the solder into the through-hole 2 for solder, the solder comes to just before the gears 5, 6. At the time of turning the gear 5 to clockwise with the hand, the thread solder is extruded with the gears 5, 6 and comes to the tip part 8 of the soldering trowel. Then, the solder is automatically stuck on the heated tip part 8 of the soldering trowel and melted.  Further, at the time of turning the gear 5 to counterclockwise, the solder is drawn back.

Title: Industrial robot
Inventor: FUJINO SATOSHI
IPC: B25J9/10
Filed: 1990-11-05
Abstract: PURPOSE:To obtain a stable control system by comparing a speed deviation with the preceding value without directly feeding back it, judging the state of the control system and then feeding back the current deviation or the preceding one. CONSTITUTION:A servo circuit 6 feeds back the rotational information of a servo motor 3 based upon the number of generated pulses counted by rotary encoders 4 and a counter 5 in order to move a robot arm 1 to a prescribed position and drives a motor driving circuit 7 based upon a command speed output corresponding to the feedback and outputted from a CPU 8. When a speed deviation  v0 fed back at the preceding time is increased for instance and a speed deviation  v1 counted at the current counting is also increased, the CPU 8 feeds back the value  v1 as a speed deviation. However when the  v1 is decreased, the CPU 8 feeds back the value  v0. Consequently, the influence of an error in the transmission system can be reduced, the oscillation of the robot arm can be suppressed and the industrial robot based upon a stable control system can be obtained.

IPC: H04B11/00
Filed: 1986-12-15
Abstract: PURPOSE:To always perform distinct underwater communication by automatically switching an upper transmitter-receiver and a lower transmitter-receiver and automatically selecting and using the lower transmitter-receiver when a submergible body is on the surface of sea water and automatically selecting and using the upper transmitter-receiver when the submergible body submerges. CONSTITUTION:When a power source is turned on, an output 16a of a reception decider 16 is automatically initialized so that code '0' is generated, and a lower transmitter- receiver 12 is selected. Consequently, when a submergible body 21 on which this submarine communication machine is mounted submerges, an upper transmitter-receiver 11 goes underwater and the signal transmitted from the lower transmitter-receiver 12 is received by the upper transmitter-receiver 11, and code '1' is outputted from the reception decider 16. As the result, a selector 10 is switched to connect the upper transmitter-receiver 11 to a transmission/reception coupler 9. In this state, the reception electric signal of the lower transmitter receiver 12 is inputted to the reception decider 16 through the selector 10, a reception detecting amplifier 14, and a band-pass filter 16. The reception decider 16 outputs code '1' when obtaining correlations between a signal 15a and a transmission electric signal 7a, but it outputs code '1' when it cannot obtain correlations.

Title: Manufacture of semiconductor device
Inventor: OGAWA HISASHI
IPC: H01L27/10
Filed: 1990-11-01
Abstract: PURPOSE:To shorten a semiconductor in a manufacturing process by a method wherein a multilayered film is patterned under a first etching condition, and irregularities are provided to the side face of the multilayered film under a second etching condition. CONSTITUTION:Silicon oxide multilayered films 7-9 different from each other in type and concentration of impurity are formed, and when the cross sections of the multilayered films 7-9 are exposed and etched, as an etching rate varies corresponding to impurity concentration, the silicon oxide film which contains impurity is quickly etched as compared with one which contains no impurity, in result large irregularities are formed on the cross section of the multilayered films 7-9. When a polysilicon 10 is deposited thereon, as the polysilicon 10 is very excellent in step coverage, it is deposited well even in the irregularities formed on the cross section of the multilayered silicon oxide films 7-9. The polysilicon 10 serving as a storage node is patterned, and then the multilayered films 7-9 of silicon oxide are selectively removed through a wet etching method, whereby a storage node 11 large in area can be formed. By this setup, a semiconductor device of this design can be shortened in a manufacturing process.
