Title: Printing apparatus
Inventor: NARA SHINICHI
IPC: B41J5/30
Filed: 1987-05-30
Abstract: PURPOSE:To enhance operability to a large extent, by temporarily stopping printing operation in response to the printing stop order input from a keyboard inputting various control orders by keys and reopening printing operation from the printing stop position in response to printing reopening order input. CONSTITUTION:When the jamming of printing paper 3 is generated or a printing ribbon is exhausted during printing output operation, an operator immediately executes the combination key operation of the code key 9a and (P) character key 5 of a keyboard 2. Whereupon, printing operation is temporarily stopped and a buzzer 17 emits sound. After paper jamming correcting operation or printing ribbon replacing work is finished, the combination key operation of the code key 9a and (P) character key 5 of the keyboard 2 is again executed. Whereupon, printing operation is reopened from the printing stop position.

Title: Fuse for igniting candle
Inventor: TAKAHASHI TOSHIO
IPC: C11C5/02
Filed: 1983-07-25
Abstract: PURPOSE:To achieve a simultaneous ignition of many candles without giving an adverse influence on an atmosphere, by utilizing a thread-like material containing a nitrocellulose. CONSTITUTION:All candles can be ignited automatically and simultaneously upon a single candle being ignited, by connecting the top ends of wicks of many candles to each other through a fusing thread-like material 5. The fusing thread- like material 5 has a nitrocellulose impregnated therein so as to ensure that all candles are reliably ignited without the chance of fire going off during the combustion. The use of nitrocellulose is preferable because of its several advantages that no ash is produced during combustion, the thread-like material can possess an appropriate rigidity when impregnated and a combustion speed can be controlled with ease. A particularly preferable nitrocellulose is one for paint with an increased degree of nitration. However, the nitrocellulose may be too rigid to break when used alone, and an appropriate rigidity can be given by adding a plasticizer or a softener such as a natural resin or a synthetic resin like a petroleum resin thereto.
