Abstract: PURPOSE:To manufacture a high-quality outside-finned tube without partial deformation on the inner surface of tube by using a plug having a tapered surface where a diameter increases gradually toward the reduction direction. CONSTITUTION:Caliber rolls 1, 2 are rotated and a tube stock 5 which is circular in section and inserted with a plug 3 is bitten between them. After the internal peripheral surface comes in contact with the outer peripheral surface of a truncated cone part 3b of the plug 3, the inside diameter is expanded with the movement of the tube stock 5 in the length-wise direction. In this process, part of the material of the tube stock 5 is bulged between flange parts 1b, 2b to form fin parts 6a, 6b. In this process, through partial deformation is formed temporarily in the inner part of the tube, the inner partial deformation is dissolved by the diameter expanding action by the truncated cone part 3b of the plug 3 and a high-quality outside-finned tube 6 can be manufactured.

Title: Exhaust gas treatment device of diesel engine
Inventor: MIYAJIMA KIYOSHI
IPC: F02B3/06
Filed: 1990-11-30
Abstract: PURPOSE:To ensure that the content of NOx is reduced and also the volume of black smoke is minimized under a simple structure by providing a device to supply hydrocarbons at a point halfway through a gas suction system and a catalytic converter which activates hydrocarbon component as a reducing agent to decompose NOx at a point halfway through an exhaust gas passage. CONSTITUTION:Hydrocarbons(HC) are ejected in a misty form to a point halfway through an aspiration system 3, using an atomization device 6, then the atomized hydrocarbons are supplied to a combustion chamber 2. After that, the atomized hydrocarbons undergo a separate combustion process from that for fuel which is directly fed to the combustion chamber 2 and unsaturated hydrocarbons which are highly effective for the activation of a catalytic converter 18, are generated. The catalytic converter 18 becomes activated with the unsaturated hydrocarbons as reducing agents to decompose NOx into N2 and O2, and thus performs a reductive catalytic action on NOx. In addition, HC are allowed to become combusted in a precombustion chamber 2 prior to the ejection of fuel from a main fuel injection nozzle 20 by supplying HC to the aspiration system 3. Then, fuel is supplied to the combustion chamber 2 to become ignited. Subsequently, the combustion is accelerated and black smoke in the exhaust gas is minimized to maintain the decomposition effect of the catalytic converter 18.

IPC: F16H59/02
Filed: 1991-12-24
Abstract: PURPOSE:To provide a shift lock device which is free from bringing about drop of the battery capacity. CONSTITUTION:During running at a high speed, a rod 33 moves forward to put a lock plate 23 in pressure contact with a lock cam 21, because a solenoid 24 is energized to move an actuator 39 in the direction of retracting. If therein a switch-back operation is performed, the lock plate 23 is fitted in a lock groove 22, and a shift lock is put in effect. When the running is at a low speed and the engine revolving speed lies within a low revolution range, the solenoid 24 is deactuated, and a first link plate 41 is restored by the reaction force of a torsion spring 25 to push back a return arm 53, so that the rod 33 moves backward and the link plate 23 is set off from the lock groove 22 to disengage the shift lock. When the power generating ability of alternator is low, the solenoid 24 is deenergized to disengage the shift lock with the reaction force of spring which is free of power consumption, and thereby drop of the batter capacity can be prevented.

Title: Cleaning device for distribution piping of water supply
Inventor: NAGAHAMA TOSHIYUKI
IPC: E03B7/00
Filed: 1989-12-28
Abstract: PURPOSE:To permit tubercle to be removed from a deformed pipe part by a method wherein a tubercle breaker is provided ahead of synthetic resin made pig and a traction wire is provided ahead of the breaker. CONSTITUTION:A pig 13 and a breaker 14 are inserted into distributing water pipe and, when a pressure water A is introduced thereinto from the rear side of the pig 13, the pig 13 is pushed by the pressure water. When the pig 13 is being passed through the distributing water pipe 11 provided with a mortar lining 12, the pig 12 is thus pushed to move forward by the pressure water, whereby any large tensile force is not required of a traction wire 24 ahead of the breaker. For this reason, a compression spring 38 is not deflected but pulls a break pawl 23 rearward into a closed condition, in which the pig moves to clean the mortar lining 12. This method permits tubercle to be removed from a deformed pipe part without impairing the lining layer.

IPC: G07D5/02
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To improve the discrimination rate of coins and make the whole device small-sized by detecting unevenness while a coin is stopped. SOLUTION: The fed coin 1 is held by a stopper 2 and a frame 3 and a probe 4 is moved by the unevenness of the surface of the coin 1; and the distance to a detection electrode 6 varies and this variation appears as variation in the electrostatic capacity of a capacitor. Then a signal processing means 8 counts a frequency outputted corresponding to the electrostatic capacity of the capacitor, a switch 14 is switched, and the capacitor is switched to the capacitor at another part. Consequently, if the surface of the coin is uneven, the electrostatic capacity varies, and the frequency outputted from an oscillation circuit also varies. The variation of this frequency and position information on the switch 14 are inputted to and stored in a pattern discrimination part.  The ring pattern of the inputted frequency variation is compared with a reference ring pattern and when they match each other, it is decided that the coin 1 is authenticity.
