Title: Battery charger
Inventor: OHARA TAKEJI
IPC: H02J7/00
Filed: 1989-10-18
Abstract: PURPOSE:To stop a charge without generating a malfunction by temporarily stopping an electric power supply from a switching power supply after a prescribed time elapses from the start of the charge, meantime taking in an output from an A/D converter and judging whether a full charge is performed. CONSTITUTION:A microcomputer 30 feeds a supply stop signal to a switching control circuit 24, temporarily stops a charge and meantime takes in the output of an amplifier 28. Whether a taken in battery voltage rises from that of previous time is judged. When 6 ms have elapsed after a charge stop, the microcomputer 30 stops the output of the supply stop signal and resumes the charge. When 3sec have elapsed after the resumption of the charge, the microcomputer 30 outputs the supply stop signal again and temporarily stops the charge. Thereafter the same operation is repeated. Thus, since the microcomputer 30 reads the battery voltage during the output of the supply stop signals, a measuring error due to a switching noise from a switching circuit 22 is not generated.

Title: Blow molding method and device
Inventor: KOHAMA YUKINORI
IPC: B29C49/50
Filed: 1991-09-25
Abstract: PURPOSE:To shorten mold clamping time at the molding of long deep formings so as to mold product, in which extremely few ununiform section develops by a method wherein parison is injected upwards and the upper end of the parison is pulled up with a pinching means synchronously with injection speed. CONSTITUTION:Parison 50 is injected upwards and raised with a pinching device 52 in synchronous with injection speed. Thus, although the temperature of the tip of the parison 50 lowers, the upward extending forces due to injection balance with the gravitational forces applied to the parison, resulting in effectively suppressing drawdown, which tends to elongate the high temperature part of a die lip part. Further, at the blow molding of deep forming product, by closing a male mold 20R in advance, sagging is produced by the lowering of a parison pinching site and the continuation of injection so as to be utilized for bringing close contact with the shoulder part of a cavity. Thus, the mold clamping work can be efficiently performed and, at time same time, the surface shape can be improved.
