Title: Abs resin composition and molded product thereof
Inventor: MUROI TOSHIMASA
IPC: C08L55/00
Filed: 1995-03-09
Abstract: PURPOSE: To obtain an ABS resin composition which can give a molded product reduced in a distribution of wall thicknesses and is excellent in low-temperature impact strength by specifying its melt flow rate and its die swell ratio. CONSTITUTION: This ABS resin has a melt flow rate of 1-20 at 220 deg.C and a die swell ratio of 20-200. To mix the components of this composition, common mixers can be used. Among them, a vented extruder is desirable. A molded product of this composition can be obtained by a vacuum molding process or a pressure molding process. When the melt flow rate of this composition is below 1, the composition can not give a desired molded product by a pressure molding process due to the insufficient deformation of resin. On the contrary, when it is above 20, the deformation of the resin is excessive, the handling of the heated sheet to the molding machine is difficult and the impact strength of the molded product lowers.

Abstract: PURPOSE:To enable the writing with high accuracy to be performed without deteriorating the throughput by a method wherein an induction compensating circuit to supply a main focus coil with current compensating an electromagnetic induction current generated in a main focus coil by the changing dynamic focus compensation coil is made in the title device. CONSTITUTION:When a dynamic focus compensation coil 13 is supplied with focus compensation current 51 at a time t1, a main focus coil 4 is supplied with induction current 52. On the other hand, induction current 53, which has the same intensity as, but in the reverse direction to, said current 52 produced by the focus compensation current 51 in the main focus coil 4, is produced through an induction compensating circuit 14 and flows into the main focus coil 4. In other words, the magnetic induction current 52 generated in the main focus coil 4 is offset by the induction current 53 flowing from the induction compensating circuit 14 to make main focus coil current 54 equivalent to the subjected to no change. Resultantly, even if the dynamic focus compensating circuit 13 is changed, the main focus coil 4 is apparently subjected to no electromagnetic induction current generated. Through these procedures, the writing accuracy can be increased without deteriorating the throughput.

Abstract: PURPOSE:To make a freezing capability variable and enable a system to be adopted for an increased freezing capability even in case of a cool-down period or in case of an increased cooling load by a method wherein a displacer and a resilient supporting means for resiliently supporting the displacer in such a way as the displacar may be reciprocated are moved in an axial direction of a cylinder, a useless capacity of an expansion chamber is made variable and a freezing capability of the freezer is freely varied. CONSTITUTION:When a freezing capability of a freezer may be low in case of performing a normal operation after a cool-down state, a displacer 18 and a resilient supporting means 23 are moved in an axial direction of a cylinder by a driving means 34 in such a way as a useless capacity of an expansion chamber 21 is reduced. As this expansion chamber 21 shows a decreased useless capacity, an amount of refrigerant gas fed to or discharged out of the expansion chamber 21 is reduced, so that a freezing capability is lowered. In turn, in case of increasing a freezing capability under a cool-down or an increased cooling load, the displacer 18 and the resilient supporting means 23 are moved in such a way as the useless volume of the expansion chamber 21 is increased. As this useless volume of the expansion chamber 21 is increased, an amount of refrigerant gas fed to or discharged from the expansion chamber 21 is increased, so that a freezing capability is increased.

Title: Method and system for repairing semiconductor integrated circuit
Inventor: SUZUKI KATSUKI
IPC: H01L21/82
Filed: 1990-03-01
Abstract: PURPOSE:To repair a semiconductor integrated circuit in accordance with the item to be repaired by providing several types of wiring having different wiring resistance lengths in advance and changing a wiring pattern by switching the wiring type from one to another in accordance with the limitation to the wiring resistance length imposed by a changed wiring pattern. CONSTITUTION:By arranging in parallel two metallic films respectively having, for example, widths of xmum and 2xmum and resistances of k1OMEGA/mm and k2OMEGA/mm (k2<k1), a resistance value of k3OMEGA/mm and a relation of k3<k1 are obtained. Thus a difference in the resistance value is obtained by using different shapes of metallic films or different kinds of metals for the metallic films. When no good result is obtained in the course of forming a circuit by using one of these wiring type, the wiring type is changed to those having looser limitations until an acceptable result is obtained. When an acceptable result is obtained, the wiring type is used for repair. Therefore, a wiring pattern having a desired value of wiring length resistance can be obtained.
