Title: Paper feed cassette for duplicator
Inventor: HIROSE YOSHIHIKO
IPC: B65H1/26
Filed: 1984-05-22
Abstract: PURPOSE:To simplify set operation and to reliably close an openable cover during non-use, by providing a reed screen-like set cover in which a feed paper opening is formed and a copy paper takes an feed paper attitude during set, and the opening is closed during non-use. CONSTITUTION:When a fed paper cassette 13, being in a closed condition, is pushed in the mounting opening of a duplicator body to set it, and a projection 12 is engaged with the side of the body. A reed screen-like cassette cover 7 is opened, and the one ends of completely blocked copy papers 8 are brought to a condition in which they are pushed over an opening 14 of the cassette 13. When the feed paper cassette 13 is removed from the duplicator body, the projection 12 is moved in a reverse direction to a direction B through the resilient force of a spring 20, the reed screen-like cassette cover 7 is closed, and simultaneously, a copy paper placing plate 9 is also lowered to contain the copy papers 8 in a cassette case 15.

Title: Magnetron driving device
Inventor: HOSHINO HIROYUKI
IPC: H05B6/68
Filed: 1990-04-19
Abstract: PURPOSE:To make circuit design, which ensures decreased power loss and withstands noise inclusion by allowing a sensing means to sense the anode current as output controlling signal, and senses the charging current as soft start release sensing signal. CONSTITUTION:At starting, first a start signal is fed from a start signal generator circuit 28 to a pulse width control circuit (PWM circuit) 9. Receiving this signal, the PWM circuit 9 gives an On signal of short duration to a switching element 6, and a magnetron 14 is supplied with a high frequency power at a low output level. Then the PWM circuit 9 prolongs duration of the On signal given to the switching element 6 and increases the high frequency power to the magnetron 14. Then the On duration is adjusted by the PWM circuit 9 so that the level sensed by a current sensing transformer CT 15 becomes as desired, and the output of the magnetron 14 is controlled. This sensing can be done satisfactorily even when output at soft starting is small, and this amperage level is sensed as a soft start disengage sensing signal. This allows accomplishing a circuit with decreased power loss and strong against noise inclusion.

Title: Method and device for molding ocular lens using vacuum injection
Inventor: KAI SHII SUU
IPC: B29C45/34
Filed: 1995-04-27
Abstract: PURPOSE: To prevent the formation of burr and the generation of air bubbles by introducing a liquid lens material into an evacuated lens mold cavity to suck the same under vacuum to fill the cavity with the lens material and then curing the lens material. CONSTITUTION: A hollow region 17 including a lens cavity 18 is formed between a mold member 1 and a projected member 16 and then evacuated via a vacuum conduit 3 by a vacuum pump 4 to bring the mold member 1 into contact with a projected member 16 under pressure. Next, when a movable gate pin 9 is drawn out from the valve seat of a fluid conduit 15, a vacuum of the lens cavity 18 draws a liquid lens material to fill the lens cavity 18. At this time, the hydraulic pressure of a pump 5 and a runner 7 also contributes to send the lens material into the lens cavity 18. Next, the movable gate pin 9 is returned to cure the lens material in the lens cavity by a UV light source 14. In this case, since the annular walls of both of the mold member 1 and the projected member 16 are brought to a contact state in the absence of the lens materials, burr is not generated.

Title: Communications terminal equipment
Inventor: NAKAGAWA TOSHITAKA
IPC: H04N1/00
Filed: 1993-04-06
Abstract: PURPOSE:To prevent useless call to a destination in which the possibility of connection is low. CONSTITUTION:A queue managing part 12 connects communication reservation management information such as the destination with a wait queue W, and sets a reserving time as a waiting time. A communicated result judging part 14 judges the normal end and failure of the communication, and supplies the result to the queue managing part 12. A redial condition discriminating part 15 discriminates the complated or imcomplate redial condition based on the communicated result, and supplies the result to the queue managing part 12. When the transmission failure detection signal and the redial condition establishment signal are supplied, the queue managing part 12 deletes the failing communication job from a ready queue R, and connects it with the wait queue W. At the same time, the queue managing part 12 resets the waiting time of the job whose destination is the same as the pertinent job at the wait queue W.
