Patent JP-S63279539-A (JP)
Title: Manufacture of cathode-ray tube
Inventor: SAITO TSUNENARI
IPC: H01J9/227
Filed: 1987-05-09
Abstract: PURPOSE:To improve luminance in a high current density area and yellowing in a fluorescent screen by rotatingly appling a phosphor slurry 12 having phosphor/slurry weight ratio of 14.0-30.0 on the inner surface of a panel, and forming thereon a lacquer film and a metallized film, thereby a fluorescent screen is formed. CONSTITUTION:A phosphor slurry 12 having phosphor/binder ratio in weight of 14.0-30.0 is rotatingly applied on the inner surface of a panel 1 and is exposed and developed thereafter to form a phosphor layer, while a lacquer film is formed on the phosphor layer and a metallized layer is formed on the lacquer film. Consequently, the phosphor charge ratio in the phosphor layer increses in a fluorescent screen to improve the density of the phosphor layer, while the mirror condition in the metallized layer is improved, resulting in that phosphor emission energy can be taken out effectively in the front face of the panel and heat generated at the fluorescent screen can be discharged efficiently to the panel face. It is thus possible to improve luminance and yellowing characteristics in a cathode-ray tube used in a so-called high current density area in a projector or the like.

Title: Disc playing device
Inventor: KIYOMIYA MASAAKI
IPC: G11B23/03
Filed: 1984-06-02
Abstract: PURPOSE:To reduce the cost and to increase the number of discs to be stored by adopting the constitution that the plate member of a lot of disc carrying units storing the discs is formed nearly in L-shape and three axes stop a play. CONSTITUTION:The cost of the disc carrying units 17 in which discs are stored while the center hole is fitted to a projection 18d is reduced because the device shaping the units is small and the number of discs to be stored is increased by increasing the unit number. Deformation of discs is prevented even if the storage section is expanded thermally by pressing the upper face of the units with a retaining plate 25. Since the shape of the major plane of the plate member 18 of the units 17 is made nearly into L-shape, a play is stopped by using the three axes 20, 21, 22 and the cost is reduced further by saving one shaft.

Filed: 1985-05-27
Abstract: PURPOSE:To increase reaction force and also improve resistance against quake, of an impeller by forming the plural number of annular grooves on at least one of the outer peripheral face of the impeller and the inner peripheral face of a diffuser. CONSTITUTION:On the inner peripheral face of a diffuser 5 opposite to the shroud 4 of an impeller 2, the plural number of annular grooves 6, 6... extending in the circumferential direction of the diffuser 5 are formed at intervals in the vertical direction of said diffuser 5.

Title: Electronic control type cooking device
Inventor: MORISHIGE MASAKATSU
IPC: F24C7/02
Filed: 1981-07-20
Abstract: PURPOSE:To prevent the frequency of starting and stopping a cooking device at the alternating time from increasing by repeating the start and stop of heating energy based on the set output altered from the starting time of the prescribed period newly starting next when the set output is altered during cooking. CONSTITUTION:When a timer knot 4 and an output knob 6 are, for example, operated to cook at 70% of the oscillation output of microwave for 10min and a pushbutton 7 is depressed to close a cook start switch 14, the microwave oscillation during 17.5sec with a period of 15sec and the oscillation stop during 7.5sec are, for example, repeated, and the cooking of 70% of the oscillation output of the microwave is executed. When the knob 6 is reset, for example, to the position of 60% during this execution, 4-bit signal representing 15sec is outputted instead of 4-bit signal representing 17.5sec from an encoder 15. Thus, the content is loaded in a counter, and the cooking with the altered output from this period is continued.
