Title: Control method for v-belt stepless speed change gear and its device
Inventor: TANAKA YOSHIKAZU
IPC: F16H61/02
Filed: 1981-03-28
Abstract: PURPOSE: To reduce drain rate of oil pressure at the time of speed change controlling in such a way that when changing oil pressure in a driving pulley cylinder chamber, oil pressure in a driven pulley cylinder chamber is maintained to  be constant, and in the contrary case , oil pressure in the driving pulley cylinder  chamber is maintained to be constant.  
     CONSTITUTION: A V-belt stepless speed change gear provides a driving pulley 24 and a driven pulley 34 which are able to regulate intervals of V-letter shaped pulley grooves by changing oil pressure in each pulley cylinder chamber 28, 44. And line pressure of a first port 122c to be led to a speed change control valve 106 is fed through second and third ports 122b, 122d to the cylinder chambers 28, 40. Said line pressure is generated by means of a pump 80, and regulated by means of a pressure regulating valve 102. In this case, the desired purpose can be realized by forming equally the distance between the outside walls of the second and third ports 122b, 122d of the speed change control valve 106 and the distance between the outside ends of first and second lands 152b, 15c of a spool 152.

IPC: B23P19/00
Filed: 1988-02-27
Abstract: PURPOSE:To surely hold a part and to enable its displacement and relocation to be prevented even halfway advancing a supply rod by holding the part to be attracted by a magnet while positioning the part by a protrusion formed in the point end part of an outer shaft. CONSTITUTION:By building an inner shaft 20 to be combined in a slidable condition in a hollow outer shaft 19, a supply rod 21 is formed. When the supply rod 21 advances, a protrusion 28 advances into a thread hole 27, and a magnet 22 holds a nut 23 to be attracted and extruded being left as it is, when the nut comes just in the vicinity of a guide pin 14 of a fixed electrode, a restricting pin 24 is lifted by an engaging piece 40 actuating an air cylinder 38, forcedly retracting the inner shaft 20. Accordingly, the magnet 22 is detached from the nut 23, because attracting magnetic force of the nut substantially disappears, the nut is placed in a condition that it is integrally formed with the guide pin 14. Thereafter, when the supply rod 21 is retracted, the magnet 22 returns by action of a compression spring 26, performing preparation for the next supply of the nut.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To surely close or cut off a packing member at a specified length, by providing a positioning means to relatively transfer a corresponding part of the packing member to the opposite direction against the transfer and secure a closing and/or cutting space. SOLUTION: This packaging device repeatedly functions from feeding of a packing member and opening motion of an opening to packing of an article and dropping of the packing member. The lift member 42 of a positioning means 6 raises the corresponding part of the packing member containing the article to be packaged. That is, the positioning means moves relatively to the opposite direction against the feeding direction of the packing member and positions the packing member to secure a welding or cutting space for closing the opening. Since a heater 27 and a pad 28 cooperate with each other in this state, the opening is securely welded and closed and the packing member is securely cut off at the forward and rearward positions of the welded part.

Abstract: PURPOSE:To set the end necessary pressure at about constant level with no energy loss by setting previously the targeted control pressure for each revolving speed of a pump, then changing said targeted pressure in response to the variation of the pump revolving speed. CONSTITUTION:A pressure detector 16 sends a pressure signal S1 which varies in response to the change of the using flow rate to a control part 21. The part 21 calculates the targeted control pressure SV from the output signal fed from an inverter 22 and according to the relation between the prescribed pump revolving speed and the targeted control pressure set every revolving speed of the pump. Then a frequency output signal with which the pump discharge pressure P is set close to the pressure SV is obtained from the difference between the pressure SV and the signal S1. This output signal is outputted to the inverter 22. Thus a motor 11 varies in the direction opposite to the changing direction of the pressure value shown by the detector 16. Then the pressure SV is controlled through control.

Filed: 1980-04-10
Abstract: PURPOSE: To prevent the elution of iron steel and the hydrogen embrittlement of the iron steel, by subjecting iron steel whose surface has oxidized film to a pickling treatment using an aqueous hydrochloric acid solution containing ferrous and firric ions.  
     CONSTITUTION: The film formed by hardening on the surface of iron steel subjected to a temper and heat refining following a martensite-hardening treatment is an oxidized film composed of FeO and Fe 2 O 3 . Thus, when the iron steel is subjected to a pickling treatment in a bath containing, besides hydrochloric acid as the main component, 60W180g/l of ferrous ion (in terms of FeCl 2 ) and 10W90g/l of ferric ion (in terms of FeCl 3 ) in a temperature range of approx. 10W60°C, the dissolution of the oxidized film is reduced under the influence of common ions and the elusion of the steel is therefore prevented. Accordingly, because on nascent hydrogen is produced, the hydrogen embrittlement of the steel can be prevented. On the other hand, when sulfuric acid radical is accumulated during the pickling bath, a Ba compound is added to the bath, and BaSO 4  is precipitated and removed.
