Title: Operation control mechanism for elevated place working vehicle
Inventor: KISHI MITSUHIRO
IPC: B66F9/06
Filed: 1990-04-17
Abstract: PURPOSE:To enable a car body to advance in the control direction of a drive lever even when a slewing body is located in any relative position between a car body and the slewing body by detecting a relative position between the car body and the slewing body and providing an inverting means to invert the control directions of the drive lever and a car body drive means to each other. CONSTITUTION:Cams 27, 28, and 29 formed on the periphery of a revolving shaft 25 are located such that straight lines X-J and I-K are separated in a 90 deg. arc from each other based on a central axis X serving as an axis, a straight line M-N is positioned in the middle between straight lines H-J and I-K, and the cam 29 is located at an upper stage. Thus, when the revolving shaft 25 is positioned at 90 deg. in a sideways direction, limit switches 30 and 31 located to a car body skirt part are not brought into contact with the cams. When the car body is rotated in a 180 deg. arc and positioned in a reverse direction, the switches 30 and 31 are brought into contact with the cams 27, 28, and 29, and through forward operation of a drive lever, the car body is advanced in the advancing direction of the lever.

Abstract: PURPOSE:To enable a smooth operation to be obtained and also the performance, vibration, fuel consumption and the like to be favorable by providing an engine with a rotating shaft which has a projecting portion or a recessed portion formed into a sine-curve like shape. CONSTITUTION:A part 5, which is attached by means of a piston rod 6 to a piston 2, and the beltlike projecting portion 4 of a rotating shaft 3 are engaged with each other. In addition, the projecting portion 4 is formed into a sine-curve like shape on the circumference. Hereupon, when the piston 2 is forced down by the combustion of fuel in a combustion chamber, the part 5 is moved by means of the rod 6 on the projecting portion 4, and consequently, the rotating shaft 3 rotates by a certain angle of rotation. Thus the rotating shaft 3 continues to rotate on an intake, compression, combustion, exhaust cycle. Thereby, a shaft, as the center of a reciprocating motion, and another shaft, as the center of a rotary motion, are parallel to each other, and their points of contact are engaged so that the same state is kept at all times, and therefore, a rational motion can be obtained.

Title: Method for evaluating junction state of welded part and method for determining weld condition
Inventor: UCHIDA KENJI
IPC: G01N3/28
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To evaluate a junction state correctly and quantitatively in a short time by deep drawing a sample at a plurality of points in a breadthwise direction of a steel band and evaluating the junction state from a press depth of a punch when a welded connection part cracks. SOLUTION: A clamping load is applied by a dice 4 and a plate retainer 6 at all times to a sample plate 5 processed and collected by a deep drawing process apparatus. In this state, a punch 3 is raised from below and pressed into a weld junction part 2 which is being confirmed from above. This process is carried out via an equal distance from 50 mm away from an edge part at each end of a steel band for a constant stroke. If the weld junction part 2 cracks, a junction intensity evaluation point is obtained from a state of the crack point and a measured press amount. At this time, the smaller (larger) the press amount of the punch 3 is, the smaller (larger) a weld intensity is and the larger (smaller) the evaluation point is. A junction state of the weld junction part 2 can be correctly quantitatively evaluated in a short time by using the evaluation point.

Abstract: PURPOSE:To secure efficient retrieving operation by displaying the maximum numbers of document names in a state where document names by means of character codes and graphic document names coexist. CONSTITUTION:This processor takes out the first document record of a retrieving result and inspects whether a document name by means of a character code exists or not. When the document name by means of the character code exists, the processor displays the document name by means of the character code and when it does not exist, the processor inspects whether a graphic document name exists or not. When the graphic document name exists (the item of a node is not zero), the processor plots the graphic document name, plots the preparing date of the document and total page number included in the document, and then inspects whether the document record belongs to the last document of the retrieving result or not. When it does not belong to the last document, the processor takes out a next document record, and when it belongs to the last document, the processor finishes the display processing of a retrieving result list. The retrieving result list as shown in the figure is displayed.

Abstract: PURPOSE:To improve discriminating capability by using an FM demodulator so as to apply FM demodulation to a color burst signal or a non-modulatin chrominance subcarrier, applying waveform shaping to a demodulation output signal so as to obtain a discrimination signal. CONSTITUTION:The FM demodulator 10 is selected to the input friquency versus output voltage characteristic shown in curve I.

Then a peak clamp circuit 11 clamps the upper/ lower peaks of an input FM demodulation signal. Further, the signal is compared with a reference voltage by a comparator circuit 15 via a DC preventing capacitor 12 and a gate circuit.
