Title: Manufacture of semiconductor integrated circuit
Inventor: OZAWA OSAMU
IPC: H01L21/762
Filed: 1979-11-14
Abstract: PURPOSE:To enhance the integrity of a semiconductor integrated circuit be sequentially forming an SiO2 film, a polysilicon film and an Si3N4 film on a semiconductor substrate, removing a part of the Si3N4 film by an anisotropic etching and forming a thermally oxidized film with the residual Si3N4 film as a mask. CONSTITUTION:The SiO2 film 2, polysilicon film 3 and Si3N4 film 4 are sequentially formed on the surface of a P type Si substrate 1, and a part of the film 4 is selectively removed by anisotropic etching such as an ion etching or the like using a photoresist mask 5. After the photoresist is then removed, a field oxide film 6 is formed by thermal oxidation with the Si3N4 film as a mask. As this time strain force occurred upon thermal oxidation is absorbed by the film 3. Thus, the crystalline defect such as dislocation or the like is not introduced into the surface of the substrate as caused by the strain force, and the leakage current can also be eliminated, the field film can be precisely formed, and the integrity of the MOSIC or the like can be improved.

Filed: 1987-06-15
Abstract: PURPOSE:To obtain a device of this design stable in operation by a method wherein a third Ps layer is formed in an isolation region which is provided between a PB layer on one primary face side of a gate turn off thyristor section and a PE layer on the same primary face side of a diode section as the PB layer without contacting the PB layer and the PE layer.

Title: Battery charger
Inventor: TANIGUCHI TOSHIYUKI
IPC: H02J7/34
Filed: 1995-06-14
Abstract: PURPOSE: To enable equipment to be used at all times by equipping a battery charger with a means which continues the supply and stop of the charging current to a battery and equipment repeatedly at constant intervals, even after stoppage of the first supply of charging currents. CONSTITUTION: When the first charging is completed, a timer starts counting. Then, this battery charger judges whether the timer has passed the set time or not until stopping the supply of charging current. This maintains the stoppage of charging if the timer has not passed the set time, and when the timer passes the set time, this begins the charge by turning on a switch 3.  Though the charging stop time is set to the length that a charging control circuit 4 can recognize enough the difference between the charging time to complement the amount of discharging in waiting condition of equipment 7 and the charging time in the case where it is charged in condition that there is no discharging of the battery 6 in nonoperating condition of the equipment 7, it is to be desired that it should be set to the time when the discharging of 10-30% of the rated capacity of the battery 6 is performed in waiting condition. When the charging is started, a control circuit 4 charges the battery 6 until it reaches a full charge. Hereby, the equipment can operate at all times.

Title: Control circuit device for switchgear
Inventor: OHASHI HIROKAZU
IPC: H01H47/00
Filed: 1994-06-29
Abstract: PURPOSE:To prevent malfunction of an electromagnetic coil, and detect breakage by connecting a switch, an electromagnetic coil, and a contact of the electromagnetic coil serially between electrodes of a DC power source, and connecting a breakage monitoring relay to the switch, and a serial circuit of a resistance and a capacitor to the coil in parallel respectively. CONSTITUTION:A switch 4, an electromagnetic coil 5, and an a-contact 3 actuated by excitation by the coil 5 and interlocked with switching action of a switchgear are connected serially in order between a positive and a negative electrode side conductors 1, 2 of a DC power source. A breakage monitoring relay 10 of the coil 5 is connected in parallel to the switch 4, and a serial (RC) circuit of a resistance 8 and a capacitor 9 is connected in parallel to the coil 5. A current of the coil 5 will not flow because the switch 4 is open when the switchgear is closed, and even when a point 6 gets in contact with a ground potential body 7 by an accident, it shows a transitive condition to flow to the RC circuit without reaching a stationary condition. Malfunction of the coil 5 can thus be prevented, and breakage can be detected by the relay 10, thereby reliability is improved.

The reaction system is heated at about the critical temperature of the dissolution solvent to remarkably decrease the viscosity of the polyether phase and eliminate the water emulsion. The aqueous phase is separated as a heavy liquid phase from the polyether phase as a light liquid phase by this treatment and, at the same time, the polyether are coagulated with insoluble polyether as a binder to facilitate the separation of the particle. EFFECT:The yield of purified polyether can be improved and the treatment cost can be remarkably reduced because a complicate operation is unnecessary in the present invention.
