Title: Manufacture of fluorescent lamp
Inventor: AKEBOSHI MINORU
IPC: H01J9/22
Filed: 1987-09-03
Abstract: PURPOSE:To make the storage stability of a solution higher, to make the formed coat smooth and easy for film thickness control as well as to make phosphor suspension applicable and dryable without baking it by making an acetylacetone metallic complex a coat forming material, and adopting an organic or inorganic weak acid or an electrolyte as an addition agent. CONSTITUTION:After an alcohol solution of an acetylacetone metallic complex as metallic oxide coat forming material is left intact as long as the specified time, a solution added with an addition agent consisting of an organic or inorganic weak acid or an electrolyte is applied on a glass bulb inner surface and dried up and then phosphor suspension using an organic solvent is applied on the top and dried up. The metallic complex applied and dried on the glass bulb inner surface comes into an ionic active state at the interface by the addition agent, whereby its interaction with the organic solvent is brought to nothing. Consequently, when the phosphor suspension using the organic solvent is applied, it is in no case dissolved and, such a possibility that a sticking quality of the phosphor is increased and a film face state is deteriorated is avoided.

Title: Record sheet transport mechanism
Inventor: KOGO AKIRA
IPC: B65H23/28
Filed: 1984-10-22
Abstract: PURPOSE:To facilitate positioning of a record sheet during its setting process by arranging thin film-like guide belts for interposing a record sheet along the total range of its passing part near both right and left edges of the record sheet and enabling the end of this belt to be opened. CONSTITUTION:Stable run of a record sheet 1 can be achieved, not particulary requiring adjustment of precise guide plates by catching the record sheet 1 on both observe and reverse faces at both right and left edges by means of guide belts 8 along approximately the overall range of passing route. In addition, even if the upper mechanical unit 6 is opened, the position of the record sheet can not be shifted because the guide belts 8 stick to the lower mechanical unit 7 and continue to retain both edges of the record sheet 1. In the case of loading the record sheet 1, the upper guide belt 8 can be opened just by lifting a stay 10 in the direction of arrow. The record sheet is set therein and the stay 10 is pushed down. Then, no positioned shift of the record sheet 1 can take place until the upper mechanical unit 6 is closed. Therefore, positioning of the record sheet is made quite easier at the time of setting the record sheet.

Filed: 1985-10-07
Abstract: PURPOSE:To attain an efficient packet transmission even to a synchronous consecutive communication data using one packet per plural frames by providing a reservation flag and a band counter area to the control section of a packet header of a packet. CONSTITUTION:In case of the synchronizing continuous communication, packet exchanges 2-1-2-n set the reservation flag of a packet, band counter set sections 7-1-7-n set initially a count corresponding to a required band to a band counter area to send a reservation packet. A supervisory controller 1 supervises the packet of a ring transmission line 8 and a band counter control section 6 applies the count control of addition or subtraction of the band counter area. When the count of the band counter area reaches the specified value of '0' or the like, the packet exchange uses a reservation packet to send the synchronizing continuous communication data. Thus, the synchronizing continuous communication of one packet per 2-frame is applied and even when the reservation flag is set, the packet where the count of the band counter area is not a specified value is used for the burst communication.
