Title: Optical disk and production of its master disk
Inventor: TAIRA KOZO
IPC: G11B7/24073
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk which facilitates increasing of density by improving the transferability and releasability of an optical disk substrate to and from a stamper. SOLUTION: The wall surface of in the track width direction of the recessed parts 2 the optical disk which is formed with recessed parts 2 constituting pits or grooves along track on an optical disk substrate 1 and is formed with a recording film 3 thereon consists of a steeper first sloping part 5a having an inclination to make the opening width of the recessed parts 2 narrower the nearer the base part side and existing on the bottom side across an inflection point 4 and a second sloping part 5b existing at the opening end side less steeper in the inclination than the first sloping part 5a.  The wall surface of the track width direction of the recessed parts 2 of the optical disk constituted in such a manner inclines gently on the opening end side and as a result, the flow of the resin at the time of injection molding of the optical disk by using a stamper is smoothed and the transferability is improved. Simultaneously, the opening end is made no more acute in angle, by which the release of the optical disk from the stamper after molding of the optical disk is facilitated. The recording film material is more easily intruded into the recessed parts 2 at the time of forming of the recording film 3 and, therefore, the formation of the recording film is easy particularly when the recording film 3 is multilayered.

Title: Reflection and defraction type zoom lens
Inventor: AOKI SHIGERU
IPC: G02B15/16
Filed: 1985-03-27
Abstract: PURPOSE:To reduce the eclipse and aberrational variation of off-axis luminous flux by employing a zoom system which moves the 3rd lens group with positive refracting power to an object side and also moves the 4th lens group with positive refracting power or the 5th lens group with negative refracting power so as to make corrections in image plane movement due to power variation when the power is varied. CONSTITUTION:When the power is varied, the 1st lens group I with positive refracting power and the 2nd lens group II with negative refracting power are fixed and the 3rd lens group III with the positive refracting power is moved to the object side. Then, the image plane movement at this time is corrected by moving at least either the 4th lens group IV with the positive refracting power or the 5th lens group V with the negative refracting power. Thus, the power is varied principally by the 3rd lens group III close to a main mirror to reduce the eclipse of luminous flux, specially, off-axis luminous flux due to the movement of the lens group.

Abstract: PURPOSE: To roll largely thick steel plate with less internal defects by compressively destructing columnar crystla structure and shrinkage porosity in the central part by applying pressure in the direction of height of steel ingot during eary period of cogging mill operation.  
     CONSTITUTION: In the rolling of a largely thick steel plate by cogging mill, pressure is applied in the direction of height of steel ingot during the early period of rolling to increase the thickness of steel ingot in order to assure a rolling ratio and at the same time in order to destruct columnar crystal structure and also compress shrinkage porosity developed with freezing shrinkage at the axial core position on the steel ingot top side. Also, the width draft when making a thickness direction drafting is kept constant and molding is made by final several passages. Thus, it is possible to roll largely thick steel plate with less internal defects by cogging mill.

IPC: H01C7/02
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To detect generation of an overcurrent by applying a PTC composition placed in a high resistance condition, when it exceeds a preset temperature, to the periphery of an insulation coating layer. SOLUTION: In an overcurrent sensing cable A, outside a wire 1 in a core part, a synthetic resin insulation coating layer 2 is formed in the lengthwise direction, and in this outside, a PTC composition layer 3 is interrupted in the lengthwise direction, and the cable is formed. Further, outside the PTC composition layer 3 is coated with an electric insulation peripheral coating layer 4. To the PTC composition layer 3, two detecting wires 5, 5' are connected and drawn out to the outside. Here, the PTC composition layer 3 is a conductive resin composition, a low resistance value is displayed at an ordinary temperature, and the composition, when it exceeds a certain temperature, is transferred to a high resistance condition. The PTC composition 3 is made by successively mixing a conductive filler in a crystalline cross-linked polymer, to be applied to the periphery of the insulation coating layer 2. Consequently, an overcurrent is generated in the case of carrying a current in the wire, when the temperature rises by generated heat, a temperature of PTC composition exceeds a preset value, the current is sensed through the detecting wire.

Abstract: PURPOSE:To produce simply an accurate reference level by storing both the ''0''-information and ''1''-information into two dummy capacities and then reading out them simultaneously with read-out of a memory cell. CONSTITUTION:A dummy cell shown in the Fig. 2 is replaced with a conventional dummy cell DC shown in the Fig. 1. The reset signal lines RO and R1 are set at high levels and both the ''0''-information and ''1''-information are stored in a dummy capacity CR.

At the same time, a dummy word line DW is set at a high level to read the information ''0'' and ''1'' out of the dummy cell. Then a reference level appears to a bit line B1. The cell capacity CS is shown as CR=CS/2, and the level of the line BO is set at VBO and VB1 when the information ''0'' and ''1'' are read out of the cell MC. Then the reference level VBR of the line B1 is shown as VBR=(VBO+ VB1)/2. Thus an optimum level is obtained.

Filed: 1986-03-24
Abstract: PURPOSE:To prevent generation of short shot, over-packing and a bad external appearance, by a method wherein pressure limiting value of an injection plunger is lowered stepwise according to a fall of an advancing speed of a screw in a transition process on the way of changeover to a dwell process from a filling process. CONSTITUTION:When a signal from a position comparator 24 is applied to a hydraulic circuit controller 40, pressure limiting value of a pressure control valve 46, which has been kept established at P0 is changed to Pt1, in a transition process. When a speed of a screw 16 is measured by converting a signal from a position.speed detector 20 by a speed convertor 26 and a speed signal to be applied to a speed comparator 28 from the speed convertor 26 falls to Vt1, a signal is applied to the hydraulic circuit controller 40 by the speed comparator 28 and the pressure limiting value of the pressure control valve 46 is changed over to Pt2. When the pressure limiting value falls to the Pt2, the speed of the screw 16 falls further and when the same falls to a speed preset value Vt2 preset by a changeover speed presetting device 36, a signal is applied to the hydraulic pressure circuit 40 by a speed comparator 29 and the pressure limiting value is made to change over to Pt3. As the value is as low as the Pt3 at the time of a start of a dwell process, over-packing is not generated.
