Title: Source voltage control switching circuit
Inventor: KONISHI HIROFUMI
IPC: H02M3/335
Filed: 1992-07-13
Granted: 1999-03-23
Abstract: In a BS (direct broadcast by satellite) timer recording mode, a constant voltage diode for controlling 18 V is directly inserted in a power circuit.  Alternatively, a delay circuit is inserted at the input of a switching circuit for switching the constant voltage diode, thus absorbing the switching time difference between 140-V control and 18-V control.  Therefore, the secondary side output voltages can be prevented from being increased, and the output voltages can be stabilized both in the BS timer recording mode (light load powering) and in the television mode (maximum load powering).

Title: Gas lighter with safety device
Inventor: YAMAZAKI NOBUO
IPC: F23Q2/16
Filed: 1992-11-17
Granted: 1996-10-29
Abstract: A gas lighter with a safety device has a lock member pivotal between a locked position, where it prevents depression of an ignition, and a released position, where it allows depression of an actuating lever.  The lock member is constantly urged to the locked position by means of a spring.  The lock member has also a finger board extending outside a lighter body and being positioned where it can be depressed with the same finger as is used in depressing the actuating lever, and a stopper being movable between the locked position, in response to movement of the lock member in one direction, and the released position, in response to movement of the lock member in the other direction.  When the lighter is not in use, the lock member is urged to the locked position to make an abutment against an abutment portion on the lighter body, thereby preventing depression of the actuating lever.  When the lighter is in use, depressing the finger board causes pivotal movement of the lock member, thereby resulting in the lock member held in the released position by an engagement of engaging portions.       Dpressing the actuating lever permits the return of the lock member to the initial position.
