Title: Plate glass for ceramic package
Inventor: NAGAI HIROKI
IPC: H01L23/02
Filed: 1990-06-18
Abstract: PURPOSE:To make breakdown, cracks or chipping difficult to occur by forming a compression stress layer having over a specific value on a surface and chamfering all corner portions and edge portions. CONSTITUTION:A compression stress layer of 200Kgf/cm<2> is formed on the surface of a plate glass for capping, all corner portions and edge portions of which are chamfered. The surface stress layer is formed by immersion a plate glass for a given time in a melt for of potassium nitrate, sodium nitrate or the like and by exchanging ions. When the value is not greater than 200Kgf/cm<2>, the strength is too low, and it is meaningless to for it. Any chamfering can be taken from among chemical or mechanical, R machining for machining into a circular shape, or C machining for machining into a sloping shape. Such plate glass are preferably used for capping plate glass of an EPROM thin type ceramic package requiring, in particular, thinness and high strength, because breakdown, cracks or chipping is difficult to occur even if various extrinsic material stresses is applied thereto.

Title: Magnetic fluid using oil as liquid medium and manufacture thereof
Inventor: IMAI TOMOYUKI
IPC: C10N70/00
Filed: 1987-06-25
Abstract: PURPOSE:To obtain a magnetic fluid which uses oils as a liquid medium, where a solid phase is not separated from a liquid phase and whose dispersion stability is excellent by a method wherein a nonionic surface-active agent and an anionic surface-active agent are adsorbed to the surface of fine particles of a magnetic oxide and, furthermore, a cationic surface-active agent is adsorbed. CONSTITUTION:A nonionic surface-active agent is added to a water suspension containing fine particles of a magnetic oxide; the mixture is ripened at a temperature of higher than a cloud point; the surface of the fine particles of the magnetic oxide is covered with the nonionic surface-active agent which does not display a hydrophile property because a hydrogen bond in a polyethylene oxide chain (a hydrophile part) at an anionic interface has been cut due to a heating operation and water bonded to oxygen has been removed; the water adsorbed to the surface of the particles is taken away. In succession, an anionic surface-active agent and a cationic surface-active agent are oriented and adsorbed easily and firmly to the surface of the fine particles of this magnetic oxide while a hydrophobic group has been directed to the outside. Because the fine particles of the magnetic oxide displaying a hydrophobic property are used as a raw material, they become a magnetic fluid where a solid phase is not separated from a liquid phase in a liquid medium composed of oils and whose dispersion stability is excellent.

Title: Ink ribbon drive mechanism
Inventor: AMADA TAKAHIRO
IPC: G07B1/06
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To detect the unused length of an ink ribbon without the necessity to provide a silver color part to the ink ribbon and without a dedicated sensor. SOLUTION: A slit disc 11 for detecting the amount of unwound ink ribbon 4 is fitted to a unwinding shaft 3 around which the ink ribbon 4 is wound, and the rotating speed of the unwinding shaft 3 is determined by the slit disc 11 and a photosensor 13. If the unused length of the ink ribbon 4 wound around the unwinding shaft 3 is large, the rotating speed of the unwinding shaft 3 is low. On the contrary, if the unused length of the ink ribbon 4 is small, the rotating speed of the unwinding shaft 3 is high. Thus it is possible to detect the unused length of the ink ribbon 4 by using the balance between these two rotating speeds.

Title: Method for selecting sense coil in electromagnetic induction type digitizer
Inventor: NAGAYAMA TADAHIRO
IPC: G06F3/03
Filed: 1985-07-22
Abstract: PURPOSE:To correct a coordinate calculation equation in a signal processing circuit by using the output voltage of a voltage amplifier to a smaller voltage in induced voltages in a coil at both ends as an offset voltage of the voltage amplifier. CONSTITUTION:At every time each sence coil is selected, the voltage (v) of a register is compared with an induced voltage M3 in a memory 19, and a voltage M3 larger than the voltage (v) when the state changes from M3<v to the state of M3>v is a maximum induced voltage, which corresponds to a voltage vp. A comparator circuit 18 compares the voltage (v) with a minimum induced voltage M1 in the memory 19, and stores the smaller voltage as the voltage M1 gain. Since the value M1 in this case, that is the value v0 has hardly the effect of an electromagnetic pen, it is equal to the offset voltage of the voltage amplifier and since the value is rewritten at every scanning, the effect of drift is avoided. Thus, the coordinate (x) calculated by the following equation is accurate; x=k*(vp+1)-(vp-1)/(vp-v0)=k*(M4-M2)/(M3-M1).
