Title: Method for quality judgement of welded product by frictional welding and its apparatus
Inventor: MAEHARA KAZUO
IPC: G01N19/04
Filed: 1980-07-16
Abstract: PURPOSE: To judge the quality of welded part during the course of welding process without any inspection process, by measuring the time required for stopping the frictional movement from the beginning to the end in the process of frictional welding.  
     CONSTITUTION: In the process of frictional welding with a frictional welding machine in which the frictional movement is produced by the rotation of a rotary shaft 4, the stopping time of the frictional movement is the main factor to occurrences of inferior goods. Because of this, for example, a frame 4' of a stopping time t s  measuring device and a leaf spring 32 are fixed to the shaft 4 so that an inertia body 31 moves freely. When the shaft 4 is being stopped, accelerated, or constantly rotated, the inertia body 31 is connected to a switch S 2  and a condenser C is charged by a DC power source DC. The voltage in the condenser C soon becomes the same as that of the power source. On the other hand, when a stopping acceleration is applied to th shaft 4 (the period during which the acceleration is being applied is proportional to the time t s ), the inertia body 31 closes and opens switches S 1  and S 2 , respectively, and discharges the electricity in the condenser C so that the voltage in the condenser is dropped. Therefore, when this voltage is measured with a voltmeter V, the time t s  can be known. When the time t s  is larger than a prescribed value, the welded product is judged as inferior.

Filed: 1980-07-16
Abstract: PURPOSE:To control the quantity of light of an exposure lamp by adding the output voltage of a photodetecting circuit to the output voltage of a voltage forming circuit which generates the voltage corresponding to the voltage across said lamp and applying the same to a comparator. CONSTITUTION:If there is an error between the output voltage of a waveform shaping circuit 34 and the reference voltage from a reference voltage generating circuit 39, the output voltage of an error amplifier 37 increases or decreases in accordance with said error, and the generating phase of the trigger pulse outputted from a trigger pulse generating circuit 41 changes as well. Hence, the conduction angle of a thyristor 32 changes and this change is fed back to theamplifier 37 by the trigger pulse to a dummy load circuit 33. Therefore, the device operates as a whole in such a way that the output voltage of the circuit 34 is made equal to the reference voltage from the circuit 39.

Abstract: PURPOSE:To obtain a semiconductor light amplifier in which gain saturation is hard to occur and amplification efficiency is excellent, by increasing the cross sectional area of a light amplifier part, which is perpendicular to a light guide in the travelling-wave type semiconductor amplifier, toward a light emitting end surface from the incident edge face of light. CONSTITUTION:A light guide comprising an active layer 3 and a clad layer 5 is formed on a semiconductor substrate 1 in a travelling wave type semiconductor light amplifier. In this amplifier, the area or the cross section of a light amplifier part, which is perpendicular to said light guide, is increased toward a light emitting end surface from an incident end surface of the light. For example, an N-InP buffer layer 2, an InGaAsP active layer 3, an InGaAsP anti-melt-back layer 4 and P-InP clad layer 5 are grown on the N-InP substrate 1 as crystals. Thereafter, two radial grooves 6 and 7 are formed in the direction of [110], and a mesa stripe 8 is formed between the grooves 6 and 7. Then, a P-InP current blocking layer 9 and an N-InP current blocking layer 10 are formed at a part other than the upper part of the mesa stripe 8. A P-InP embedded layer 11 and a P<+>-InGaAsP contact layer 12 are grown on the entire surface as crystals.

Title: Switched capacitor circuit
Inventor: KITA MASAHITO
IPC: H03H19/00
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To permit the influence of feed-through noise to be min. and to improve the arithmetic precision of an integrating equipment, etc., and the converting precision of an A/D converter by setting the timing of the control clock of a switches so as to permit feed-through noise not to give difference to the arithmetic result of an operation amplifier. SOLUTION: When the switches are turned off in order of SW4→SW1, a node N2 becomes floating and, then, the switch SW1 is turned off so that feed- through noise generated by the switch SW1 is not stored in sampling capacitance C1. When the switches are turned on in order of SW3→SW2, the potential of the node N2 is the same as that of the node N3 before turning on the switch SW2 so that feed-through noise generated at the time of turning on SW3 is fixed regardless of the charging voltage of sampling capacitance C1 and the variation of integrating precision owing to feed-through noise is prevented. Therefore, the influence of voltage dependence in feed-through noise which is generated in the switches SW1-SW4 is restricted to min.

Abstract: PURPOSE:To execute the fetching of pictures of a moving body without a special sensor in terms of a picture processor for recognizing motions by deciding the entry of the moving body to an image pickup visual field only based on picture data of the moving body. CONSTITUTION:Pictures to be processed by a picture processor 80 includes two types; one is a picture for detecting whether or not a moving body enters an image pickup visual field, and the other is an entire picture obtained when the moving body completely enters said field. In a moving body entry mode, binary data of a binalization circuit 81 is cumulatively added. When said data reaches a reference value where a distribution cumulative value of the circuit 81 serves as a reference of the entry of the moving body, the moving body is decided to enter. A processor 100 executes the arithmetic comparison of this cumulative arithmetic and the reference value. Under a moving body overall monitor mode, the time when the entire picture of the moving body sufficiently enters the visual field of the image pickup surface is caught, and the entire image picked up on the image pickup surface is fetched to a processing part 120.
