Title: Local reducing method for thickness of plate material
Inventor: YASUDA KENICHI
IPC: B21B1/22
Filed: 1981-09-30
Abstract: PURPOSE:To form a thickness reduced part free from deformation by rolling the desired part of a plate material continuously and thinly in a longitudinal direction and deflecting the centerline at the section in the width direction of the plate in the desired part. CONSTITUTION:A plate material is rolled by a roll 2 having a projecting part and a roll 3 having a recessing part, by which a thickness reduced part having deflection can be formed continuously in the longitudinal direction of the material 1. The min. thickness (he) in the thickness reduced part is he<h as compared to the thickness (h) of the material 1, but the relation between the average width b2 of the deflection and a rolling width b1 is b2>b1 and the area (shaded part) in the thickness reduced part is approximately equal to hXb1, which indicates that no longitudinal deformation by the rolling is generated. The deflection is virtually annihilated when the material passes between the deflecting rollers, and does not obstruct coiling of the material.

Abstract: PURPOSE:To surely slit a connected bar base stock and execute stable dividing by arranging slitting rollers which are rotatably driven with a driving means and with which intermediate multi-bar base stocks are slitted in connecting parts on the outlet side of a slitter. CONSTITUTION:In the case of manufacturing four lines of bar stocks 19, for example, first, a billet is rolled with a rolling mill 1 made into a parallel-like of the four lines of bar base stocks 6 and formed into a multi-bar base stock 8 which is mutually connected in an approximately close-contact-like with thin connecting parts 7. Next, the multi-bar base stock 8 is divided by slitting a the center connecting part 7 with a slitter 2 which is arranged on the outlet side of the rolling mill l and formed into two lines of the intermediate multi-bar base stocks 11. Each of the intermediate bar base stocks 11 is divided by slitting with the slitting rollers 12 which are arranged on the outlet side of the slitter 2. Since the slitting rollers 12 are turned with the driving means 15, no resistance to the longitudinal direction of the bar base stock 6 is present and the intermediate multi-bar base stocks 11 are goodly divided without buckling.

Filed: 1982-09-06
Abstract: PURPOSE:To obtain a C-MOS inverter without through-current, by connecting N/P type MOSFETs in parallel between a gate of the C-MOS inverter and an input terminal and making the conductance different from each other. CONSTITUTION:P/N type MOSFETs Q3, Q4 and N/P type MOSFETs Q5, Q6 are connected respectively in parallel with each gate and an input terminal IN of the C-MOS inverter comprising the P/N type MOSFETs Q1, Q2, and the conductance of the Q3, Q5 is set small and that of the Q4, Q6 is set large. An output signal of the inverter is impressed to the gate of the Q3-Q6, and the gate of the Q1, Q2 is provided respectively with N/P type MOSFETs Q8, Q7 for the gate in parallel with the Q5, Q6 and Q3, Q4. When an input signal VIN changes from L to H level, the gate voltage V1 of the Q1 is risen with the Q4 faster and the gate voltage V2 of the Q2 is risen slowly with the Q5, then no through-current flows. The Q8 prevents unnecessary delay of the leading of the V2.

Abstract: PURPOSE:To achieve a high eficiency of ion beam utilization even if the cross- sectional area of an ion beam is increased, by shaping as arc the cross section of the ion beam pull-out portion of each electrode which functions to pull out the ion beam from an ion source. CONSTITUTION:The cross section of at least the ion beam pull-out portion of each of the pull-out electrode 16 and deceleration electrode 18 of a pull-out electrode system 14 is shaped as arc. An ion beam 20 having an arc-shaped cross section of about W2 and L2 in width and length is pulled out from an ion source 2 having the electrodes, so that the beam is irradiated upon a wafer 24 on a disk 22. Since the inner and outer arcs 201, 202 of the cross section of the ion beam 20 are shaped nearly along envelopes 242, 241 on the outsides and insides of the wafers 24, respectively, the width SW2 of relative scanning with the ion beam can be reduced. A high efficiency of beam utilization can thus be achieved even if the cross-sectional area of the ion beam 20 is increased.

Title: Capacitive weight detector
Inventor: ARAI ISAO
IPC: G01L1/14
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To simplify an operational circuit and reduce cost by securing the wide side of a movable electrode plate to the wide side of a fixed electrode plate, such that the movable electrode plate is applied with a load and separated from the fixed electrode. SOLUTION: A movable electrode plate 35 is made of an unbending material into a cantilever spring and a fixed electrode plate 30, disposed oppositely to the electrode plate 53, has a substantially similar trapezoidal shape. Consequently, the variation of inter-pole gap is small on the supporting side of the electrode plate 35 and increases on the free end side. But since the area of the opposing electrode parts is large on the supporting side and small on the free end side, the capacity is average and the capacitance varies extremely linearly, thus causing a linear variation in the oscillation frequency of a detection circuit. This arrangement realizes an inexpensive, simplified circuit for operating the heating conditions, including a heating time by expressing the variation of capacitance, in terms of the weight of a material to be cooked.
