IPC: A23L17/60
Filed: 1984-04-25
Abstract: PURPOSE:To make it possible to prevent the bonding of a mold to seasoned laver and perform continuous press cutting work, by superposing each sheet of dried (toasted) laver having no adhesive property on the topmost and lowermost parts of the plural suerposed seasoned laver sheets, and press molding the laver.

The dried or toasted laver 2 is then peeled. The molded sheets of the seasoned laver 1, 1... are very easily and smoothly peeled from the mold due to the superposition of the dried or toasted laver 2 on the topmost and lowermost parts. Furthermore, moisture absorption rate of the dried or toasted laver 2 is considerably lower than that of the seasoned laver 1, and the drying holding time is long so much. Thus, sufficient time may be allowed for the packaging work. The laver 2 is peeled just before the packaging.

Abstract: PURPOSE:To obtain a positive temperature coefficient thermistor device where a positive temperature coefficient thermistor element is not distributed unevenly by holding the positive temperature coefficient thermistor element by means of spring terminals inside a case. CONSTITUTION:The following are provided: spring terminals 16 used to hold a positive temperature coefficient thermistor element 14 in such a way that it does not come into contact with inner wall faces of a case 12; stoppers 20 which have been formed collectively together with inner walls of the case or the spring terminals 16 in such a way that the positive temperature coefficient thermistor element 14 does not come close to the inner walls of the case 12 at more that a prescribed value. Where there is a difference in a spring force between the individual spring terminals 16 pressing the positive temperature coefficient thermistor element 14, the spring terminal whose spring force is strong pushes the positive temperature coefficient thermistor element to the side of the spring terminal whose spring force is weak. In this case, however, the stoppers 20 which have been formed collectively together with the inner walls of the case 12 or the spring terminals 16 are provided; accordingly, the positive temperature coefficient thermistor element is not distributed unevenly in such a way that it comes close to the inner walls of the case at more than the prescribed value. By this setup, its uneven distribution is not caused; a heat diffusion coefficient of the positive temperature coefficient thermistor element 14 is not changed largely; its stable operation can be expected; its power consumption can be reduced.

Abstract: PURPOSE:To prevent transmission of an incomplete data due to halfway of a page by connecting a G3 facsimile equipment and an ISDN network and deciding the valid invalid data in response to the picture data quantity when a picture storage memory is occupied at the G4 facsimile communication so as to start the communication. CONSTITUTION:G4 facsimile communication is implemented between an ISDN interface 7 and a G3 facsimile equipment 6 via a MODEM 5 and a picture data is stored in a picture storage memory 2.
