Title: Inter-station trunk line control system
Inventor: KIKUCHI YOSHIHARU
IPC: H04M7/00
Filed: 1988-03-25
Abstract: PURPOSE:To make an effective use of a trunk line by providing a busy tone receiver in a subscriber line exchange, detecting a busy tone through the trunk line, and recovering the trunk line. CONSTITUTION:A trunk exchange 6 knows that a call is a call to a callee subscriber 12, and selects an out-going trunk OGT 8. At this time, a route to be connected to the subscriber 12 including the OGT 8 is busy, the exchange 6 abandons the connecting action, but connects a busy-tone trunk BT 9 instead of the OGT 8 with an in-coming trunk ICT 7, and thus informs a caller subscriber 1 of that the line is busy. The subscriber 1, though he knows that the connection is impossible, does not necessarily hook off. A busy tone transmitted from the BT 9 is received by a busy tone receiver B-REC 5, and the B-REC 5 thus detected the busy tone immediately re-start the subscriber line exchange 2, and changes the connection of the caller subscriber 1 from the OGT 3 to a BT 4, so that a busy tone is transmitted from the self-office to the subscriber 1. Simultaneously with this, an OGT 3 is recovered, and thus the trunk line is effectively used.

Title: Apparatus for improving combustion of mixture in four-cycle internal combustion engine
Inventor: OOTANI JIYUNJI
IPC: F02M25/07
Filed: 1979-06-09
Abstract: PURPOSE: To reduce the amount of noxious uncombusted components contained in exhaust gas of an internal combustion engine, by providing in the exhaust system a means for producing swirl in the combustion chamber by combusted gas flowing back into the combustion chamber, and thereby improving combustion of mixture, in particular, in low-load operational range of engine.  
     CONSTITUTION: On the wall of combustion chamber 4, there is formed a swirl producing guide wall 14 for producing swirl of combusted gas flowing back into combustion chamber 4 through exhaust passage 10 when valve opening time of intake valve 12 and that of exhaust valve 13 are overlapped. Reflection flow of combusted gas flowing back into combustion chamber 4 through exhaust passage 10 and colliding onto an arcuate inner surface of guide wall 14 is converged and flows in combustion chamber 4 in a strong swirl directed in the same direction. In particular, when engine is operated in its low-load operational range, fresh mixture introduced into cumbustion chamber 4 is governed by the swirl of back-flow combusted gas since the amount of intake air is small, and resultantly, the back-flow combusted gas fresh mixture mixed together flow in combustion chamber 4 forming a strong swirl therein.

Title: Pre-load measuring method for gear meshing unit and device thereof
Inventor: TOGAWA ZENTA
IPC: G01M13/02
Filed: 1995-03-30
Abstract: PURPOSE: To measure the timing when one shaft is reversed from the driving state to the driven state on the basis of the tilt angle of the torque rate by continuously measuring the revolving speed and torque of one shaft, differentiating the revolving speed and torque of the shaft, and also converting them into the torque rate as a line segment inclined by the prescribed angle. CONSTITUTION: The revolving speed θ of a secondary shaft is continuously measured by a revolving speed sensor 13, the torque T is continuously measured by a torque meter 14, and their wave-shapes are displayed on an oscillometer 15. At the same time, the revolving speed θ and torque T are differentiated by a torque rate calculating means 16 to calculate dT/dθ. It is converted into the change rate of the torque T by a converting means 17 as a line segment X inclined by the prescribed angle.  The torque T is assessed as the pre-load of the shaft at the point where the line segment X is changed to a different tilt angle at the timing when the peripheral speed of a differential gear exceeds the peripheral speed of a secondary gear and the secondary shaft is reversed from the driving state to the driven state, i.e., near the point where the tilt angle of the line segment X becomes zero.

Title: Light beam working device
Inventor: TANI MITSUKIYO
IPC: B23K26/21
Filed: 1983-04-27
Abstract: PURPOSE:To provide a light beam working device which eliminates the light in an unnecessary wavelength region by constituting the device in such a way that the light beam condensed through a liquid absorbing the light of a specific wavelength is irradiated to a work. CONSTITUTION:A prescribed liquid is filled in a liquid tank 7 and is kept circulated. A lamp 1 is properly lighted and the light beam 5 generated by the lamp is reflected on a condensing mirror 2 and is then passed through the tank 7. The light of the unnecessary wavelength region is absorbed by the liquid in the tank 7 and the light beam 5 removed of such light is condensed on a focusing point 14, by which a work 6 is worked. The continuous wavelength band of the high-voltage arc lamp can be consequently controlled according to the material of the work and therefore the working is made possible without damaging the adjacent material susceptible to heat. There is particularly the effect of decreasing thermal load by removing the absorption wavelength of plastics in the case of applying light energy to a metallic part in brazing of such a work in which the plastic material exists adjacently to the metal.

Title: Valve driving equipment for 4-cycle engine
Inventor: FUJIKAWA TETSUZO
IPC: F01L1/06
Filed: 1985-04-05
Abstract: PURPOSE:To shorten an output shaft connected to a crankshaft and thereby make an engine smaller by installing interlocking mechanisms for opening and closing valves in an opposite direction with the core of the output shaft as its center and arranging the lifting action of individual inlet and outlet valves through the interlocking mechanisms. CONSTITUTION:When a crankshaft rotates, the follower 39e of the interlocking mechanism 34a for an inlet valve, for instance, is guided by a guiding groove 32 formed in the output part 25a of the crankshaft. And while the crankshaft rotates twice, the follower 39e slides over the entire periphery of the guiding groove 32, rotating the entire oscillating member 38 around the supporting shaft 36. Then, the cam part 39c of the oscillating member 38 moves round the auxiliary shaft 36. As a result, a plain tappet 40a pressed against the cam surface 39d of the cam part 39c moves up and down within the range of the lifting volume R, opening or closing an inlet valve. Since the interlocking mechanism 34b for an outlet valve is placed in the opposite position to the above- mentioned interlocking mechanism 34a with an output shaft part 25a as its center at this time, it opens or closes the outlet valve in about 180 degrees phase difference from the inlet valve.

Filed: 1982-04-30
Abstract: PURPOSE:To enable to change the pitch by small force by a structure wherein the change of the pitch is performed by oblique guide grooves provided on an input shaft reciprocating within a propeller shaft while the twisting torque applied on each blade is received by a hub casing. CONSTITUTION:The blades 7 are mounted to the propeller shaft through the hub casing members 6.

Title: Solder, solder connecting method and mounting structure for electronic component
Inventor: YAMAMOTO KENICHI
IPC: C22C13/00
Filed: 1995-03-30
Abstract: PURPOSE:To prevent the generation of a bridge by using solders having smaller surface tension than that of Sn-Pb eutectic solder and different solid- and liquid- phase temperatures. CONSTITUTION:Since eutectic solder has no difference between solid- and liquid- phase temperatures, the solder arriving at a melting point abruptly forms an unstable state due to the operations of a wet spreading strength, surface tension tending to be integrated with liquid and the gravity. Solder paste tends to, when becoming a high temperature, form a bridge by the operation of the tension. In order to improve it, solder having small surface tension and a difference between solid- and liquid-phase temperatures is used. An experiment for measuring the melting separability of the solder is conducted by using a solder copper 1, a copper pad 2 and a glass epoxy board 3. This experiment decides the separability by the state of the bridge formed after a solder line 1 is placed on the pad 2 and then allowing it to reflow.
