Abstract: PROBLEM TO BE SOLVED: To reuse a bath without mixing harmful impurity ions by adding a double salt of sulfate, chloride. etc., of metals to an electroless Ni-based metal plating bath containing sodium hypophosphite as a reducing agent to regenerate the bath and crystallizing and precipitating accumulated sodium sulfate to remove. SOLUTION: A sulfate, chloride, carbonate, hydroxide or double salt of a metal same as the metal which constitutes the plating film to be precipitated from an electroless plating bath is added to the electroless plating bath. Otherwise, if two or more kinds of metals are to be precipitated, a salt of at least one of the metals is added to the bath. The plating bath contains a water-soluble sulfate of the metal to be precipitated by electroless process, a complexing agent and NaH2 PO2 as a reducing agent and has accumulation of Na2 PO3 . The amt. of the salt to be added is determined to give higher metal concn. than the metal ion conc. in the plating process of the bath. The insoluble hypophosphite thus produced and precipitated is removed to regenerate the bath. Thereby, the bath can be repeatedly used. When Na2 SO4 is accumulated over a specified amt., the plating liquid is cooled to a lower temp. than room temp. to crystallize and precipitate Na2 SO4 to remove.

Abstract: PURPOSE:To enable printing to be automatically, in a conveniently punctuating manner, performed to an end of a logical page by a method wherein forms are taken as web bread at a point of time when printing of the end of the logical page is detected without taking it as the web break to the end of the logical page of a data in printing after detection of the web break. CONSTITUTION:When an end (lx) is detected with a web break detection sensor 2 and forms are web break, whether a second logical page end signal D2 is detected or not is judged. When not the end, a web break flag is reset. When the signal D2 is detected and printing of the end of the logical page is confirmed, the web break flag is set by a web break flag set means 5. Therefore, all two logical pages are printed near to a rear end of the second page of the forms. It can be prevented thereby that printing is performed to a middle of the second page. In the case where the web break flag is set, the web break is reported to a host and besides reception of the data is prohibited. Further, a preliminary taken data is made not to be printed until continuous forms are reset.

Abstract: PROBLEM TO BE SOLVED: To dispense with a large-scale transformer in a converter main circuit by forming a current control system in which the current commands of each phase obtained from a voltage control system are respectively compared with the input current detection signals of each phase of a converter main circuit. SOLUTION: In control devices 51 , 52 , as shown in the control device 52 the DC component of the current detection signal IV of a V-phase is adjusted by an offset adjustment value IOSET to pass it through an amplifier 73 , thereby obtaining a current detection signal IV1 in which the DC component is zero, and the current detection signal 1V1 is compared with the current command IV5 of a multiplier 11V. When a lag is generated in the switching time of the semiconductor element of converter main circuits 31 , 32 and a circulating current is generated between the main circuits 31 , 32 , the AC component and the DC component are detected by a Hall transformer connected to each phase and the DC component is controlled so as to be zero together with the AC component.  As a result, the circulating current of AC and DC components between the converter main circuits 31 , 32 is suppressed and the DC component becomes zero and for that reason, the AC input side of the main circuit 31 , 32 dispenses with a transformer.

Title: Steering control device for vehicle
Inventor: YAMASHITA MASAHARU
IPC: B62D5/083
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To obtain a prescribed preset load and a good steering feeling with no stepped feeling without requiring a high accuracy of assembling position. SOLUTION: A groove 42 is formed on a V-notch ring 40 fixed on a valve body of a control valve and a ball 52 is disposed in the groove 42. A retainer 50 is fixed on a valve shaft. The retainer 50 has a flexible press portion 46 which can move in an axial direction and presses and holds the ball 52. The press portion 46 presses the ball 52 with the rotation of the valve shaft to apply a force to start moving in the groove 42 to the ball 52 as a preset load. Since the press portion 4 absorbs the error of assembling position, a good feeling with no stepped feeling is obtained in the beginning of steering before steering torque reaches a preset load.

Title: Scanning type electron microscope and similar device thereof
Inventor: KURODA KATSUHIRO
IPC: H01J37/244
Filed: 1989-07-17
Abstract: PURPOSE:To improve the resolution in the low-acceleration region and improve the detection efficiency of secondary electrons by axially symmetrically arranging a detector, providing an auxiliary lens between the detector and a lens, and changing the orbit of secondary electrons. CONSTITUTION:Secondary electrons 6 emitted from a sample 4 are detected by a secondary electron detector 7 as an image signal. The negative voltage VR is applied to the sample 4 to decelerate an electron beam 2. Secondary electrons 6 are reversely accelerated by the decelerating voltage VR so that secondary electrons 6 can sufficiently reach the region where the electron field of the detector 7 is exuded by an auxiliary lens 8. The magnetic field by the auxiliary lens 8 only slightly changes the path of secondary electrons 6, the energy of the primary electron beam passing this region is high, thus the primary electron beam is rarely affected in a primary electron beam path 21. A high-resolution secondary electron image can be obtained with the low- acceleration voltage.
