Title: Japanese language identifying system
Inventor: HAYASHI TAKAO
IPC: G06F3/00
Filed: 1980-03-12
Abstract: PURPOSE:To facilitate an easy identification among the kana (Japanese syllabary), Chinese characters and phrases respectively for a processing system that edits an input of a kana sentence into a sentence including Chinese characters, by detecting the difference of key touches in the key operation of a kana keyboard. CONSTITUTION:The pressing force P of the kana key 10 on the keyboard 1 is reduced and increased for a kana letter and a Chinese character respectively. Thus the strong and weak detection signals B1 and B2 are obtained. On the other hand, the character code C is selected through the character detecting circuit 5 and regardless of the force P. The signals B1 and B2 are identified at the identifying circuit 4, and thus the Chinese character signal K and the kana letter signal N are produced to be sent to the converting circuit 6. The circuit 6 extracts the necessary Chinese characters or phrases out of the dictionary table 7 by using the signals C, K and N to exchange them with the kana letters of a kana input sentence. Then these kana letters are sent to the sentence memory 8 in the form of a sentence signal S to be stored there. The signal S is then read out to be displayed at the display part 9.

Abstract: PURPOSE:To secure a predetermined board thickness by a controlling surplus expansion of the circumference of a part of a short side of a sheet and preventing the sheet from thinning locally, by a method wherein heating, softening and vacuum molding of a thermoplastic resin sheet are performed by fixing a long side of the same, and keeping a short side of the same free by making use of a drape and plug assist and using a preblow jointly. CONSTITUTION:Only a long side of a sheet is clamped, and a short side of the same is made free by a clamping device 6 fixing a rectangular thermoplastic resin sheet 5 onto an opening part of the top 14 of a chamber. After the sheet has been heated and softened sufficiently, compressed air is blown into the chamber. In this instance, the long side is left on the top of the chamber, and the short side is turned into a state where the same is blown up from the top 14 of the chamber. At a point of time when a vacuum mold 8 is ascended up to the top 14 of the chamber, blowing-in of the compressed air is suspended. A part of the short side of the sheet is dropped onto the vacuum mold 18 through gravity. A predetermined form is obtained by accelerating a falling motion and transferring a molding form to the sheet by drawing a vacuum during the motion.

Title: Heating device
Inventor: NAKANO OKIHIKO
IPC: F24C7/06
Filed: 1988-02-15
Abstract: PURPOSE:To enlarge the heating chamber in effective volume in the device and enhance the heating efficiency by covering from the outer side the plate-shaped heating element placed in contact with the outer surfaces of the walls with reflecting plates of metal with some space therebetween and by using such reflecting plates having a high reflectivity resulting from surface treatment on the side facing the heating element. CONSTITUTION:Above the top surface 2 and under the bottom surface 3 of a heating chamber 1, a length of plate-shaped heating element 4, 5 is placed in contact with the outer side of the respective metal plate enclosing the heating chamber, and the respective plate-shaped heating element is covered from the outer side with a reflecting plate 13, 14 consisting of a thin metal plate with a layer of void space 11, 12 therebetween. A layer with a thickness of 2-3mm suffices for the void space 11, 12. A high reflectivity is imparted to the reflecting plates 13, 14 on the surface facing the plate-shaped heating element 4, 5 by such surface treatment as zinc plating or aluminum plating on a steel plate and, furthermore, by luster treatment such as bright treatment. The luster can further be enhanced by a specular finish such as buffing after plating. In order to prevent the temperature of the reflecting plates from rising, cooing air can be passed through the space between the reflecting plates and the outer casing so as to cause exchange of heat to take place on the surfaces. Thus the desired effect can be achieved without using costly stainless steel plates.
