Patent JP-S62120107-A (JP)
Title: High frequency amplifier device
Inventor: USUI AKIRA
IPC: H03F3/60
Filed: 1985-11-20
Abstract: PURPOSE:To reduce the deterioration in the gain at the reception of a high frequency band signal by coupling a cross point between a high frequency coupling coil and a choke coil and a cross point between a low frequency switching diode and a choke coil by means of a coupling capacitor. CONSTITUTION:The cross point between the high frequency coupling coil 110 and the choke coil 106 and the cross point between the low frequency switching diode 103 and the choke coil 105 are coupled by a coupling capacitor 107 and a signal is extracted from the cross point between the coupling coil 110 and the switching diode 104. A VHF band signal is outputted at the cross point between the diode 103 and the coil 105. The signal is fed to the next stage from a terminal 1E via the capacitor 107, a resistor 111 and the coil 110. On the other hand, a UHF band signal is affected by a stray capacitance 109, but since the inductance of the coil 110 is sufficiently larger than the UHF band signal, a stray capacitance 108 is shut from the signal path.

Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To enable the cutting from mid-way of an optical transmission line and the transmission with good connection efficiency and simple and inexpensive installation by putting the optical transmission line always perpendicularly to a light source and executing the work by using receiving fittings in a manner as to allow assembly at the time of connecting the light source and the optical transmission line. SOLUTION: A sleeve having the same outside diameter as the outside diameter of an optical transmission line cover is formed on the outer side of a sleeve having the same inside diameter as the outside diameter of the optical transmission line (optical fiber, etc.). For example, the sleeve 1 is formed to the same diameter as the diameter of the optical fiber and the sleeve 12 is formed to the same as the protective cover of the optical fiber. If the optical fiber is connected by using the fittings, the easy concentrical connection is made possible without the misalignment.  Next, the end face which induces irregular reflection is covered with a transparent material having the same light refractive index as the light refractive index of the optical fiber even in the case where the cut surface at the front end face of the optical fiber is nonuniform to usually give rise to the irregular reflection and the optical transmission is infeasible or its transmission efficiency is low, thereby the end face finishing is indispensable. The execution of the efficient light transmission is thus made possible.

IPC: F02D41/36
Filed: 1984-12-12
Abstract: PURPOSE:To reduce a shock in time of cylinder selection, by rarefying an air- fuel ratio by degrees after a cylinder number reducing condition is materialized, when selecting from the whole cylinder running to the partial cylinder one. CONSTITUTION:That whether a condition of shifting from the whole cylinder running to the partial cylinder one is materialized or not is judged by a cylinder- number reducing condition discriminating part 4a. If the condition is materialized, an air-fuel ratio is set to a value which is gradually increased in proportion to the elapse of time from a theoretical air-fuel ratio. When this setting value becomes more than the specified value, it shifts to the partial cylinder running, while the air-fuel ratio is made into the thereoretical air-fuel ratio. With this constitution, a shock in time of cylinder selection is reduced.

Afterwards, similar mounting work is repeated. In this case, since the LED elements 2 are taken from different taping reels, even when there is difference in the luminance among the elements, the low luminance LED elements 2 are mounted while being distributed over the entire panel.

Filed: 1989-10-06
Abstract: PURPOSE:To improve the reliability of connection by forming a terminal installing groove by radiating laser beams on one side surface of the end of a flat cable, and an exposed part of a core wire on the other side surface. CONSTITUTION:The core wire 2 of a flat cable 1 and the terminal 11 of a connector 10 are superposed, and the exposed part 8 of the core wire 2 is irradiated by laser beams 14. The focus 13 of the laser beams 14 is set near the surface or at the inside of the core wire 2 by a focus lens 15, and the output of the laser beams is regulated rather stronger being higher than at the removing time of a covering material 3. As a result, the core wire 2 and the terminal 11 are connected strongly. For one set of the connected core wire 2 and the terminal 11, welds are set at two positions. In such a way, the covering material 3 can be removed by the laser beams 14 simply and securely, the connection is also carried out by the same beams 14, and they can be automated to carry out continuously. Since the covering material 3 functions to position the core wire 2 to the terminal 11, little load is imposed to the connection even though the cable 1 is moved after connecting, a damage and a breakdown can be prevented, and the reliability of connection of the cable 1 and the connector 10 can be improved.

Title: Alloy plating adhesion amount meter
Inventor: SATO MASAO
IPC: G01N23/223
Filed: 1984-12-12
Abstract: PURPOSE:To rapidly analyze a total adhesion amount and content in a non- destructive state, by measuring KalphaX rays and KbetaX rays of one component in a two-component single plating layer comprising Fe-Zn and utilizing the effect difference of the coexisting element corresponding thereto. CONSTITUTION:When KX rays of Zn are emitted in Fe-Zn alloy plating, said KX rays are absorbed by Fe interposed in said plating. Because the absorbing ratio by Fe is different between ZnKalphaX rays and ZnKbetaX rays, the Kbeta/Kalpha ratio of Zn changes corresponding to Fe-content as a result. In actual measurement, a total adhesion amount is determined according to a formula (total adhesion amount)=(Zn adhesion amount)/(1-Fe content) by using the calibration curve of a Zn-adhesion amount and that of Fe-content.
