Title: Image forming device
Inventor: ITO AKIRA
IPC: B41J31/14
Filed: 1990-10-05
Abstract: PURPOSE:To enable undulation, wrinkles, etc., generated on a back surface of an ink sheet to be absorbed in irregularities by a method wherein a charge supply means is so arranged as to come in contact with the back surface of the ink sheet and a surface of the charge supply means is made irregular. CONSTITUTION:A purpose for formation of irregularities 4 on a surface of a charge supply means 7 is that through undulation, wrinkles, etc., are generated on a back surface of an ink sheet 1, contact of the back surface of the ink sheet 1 with the charge supply means 7 is secured by absorbing the undulation and wrinkles in the irregularities, and a charge is surely supplied to the back surface of the ink sheet 1 from the charge supply means 7. Therefore, the irregularities should preferably by a substance of rho of the same extent as the charge supply means 7 or of higher conductivity i.e., a substance of low rho. The ink sheet 1 is carried in the arrow 20 direction by a carrier means. An image forming means 30 consisting of a write head capable of transferring an ink layer 3 by heat such as a thermal head, a stylus head (an electrification head), etc., forms an image on a medium 5 moving in the arrow 21 direction.

Title: Impregnated type cathode and its manufacture, and arc lamp
Inventor: TANABE SHOJI
IPC: H01J9/04
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an impregnated type cathode capable of being stable operation even at the time of high output operation of an arc lamp and its manufacturing device as well the arc lamp. SOLUTION: A porous tungsten is machined in a truncated cone shape to form a cathode peripheral part 12 of a cathode body, and a cathode central part 11 is inserted in a centered hole under pressure. Into the outside a compound containing BaO, CaO, Al2 O3 in the mol ratio of 6:1:2 as material of easily emitting electrons is impregnated after they are heated and melted at the temp. of 1700 deg.C. Then, the outside of the part 12 is covered with a metal layer having a high melting point made of a tungsten sheet, and the lower part is welded and fixed, thereby forming an impregnated type cathode 15. When the cathode 15 performs arc discharge operation a barium oxide impregnated as the material of easily emitting electrons into the part 12 is melted out to move to the tip of the part 11 for allowing arc discharge operation.

Title: Cassette loading/unloading device for tape recorder
Inventor: YOSHIMURA TOSHIO
IPC: G11B15/675
Filed: 1990-10-05
Abstract: PURPOSE:To lightly load to a cassette into a tape recorder by providing a gap at the coupling part between a cassette take-out operation member and a spring holder member and hastening the inverting action of an inverting spring. CONSTITUTION:A gap G is provided in the moving direction of a cassette take- out operation member 25 at a coupling part between the member 25 and a spring holder member 13. An inverting spring 20 has a quick inverting action as shown by a double dot chain line as soon as the spring 20 passes through a dead point. At the same time, the member 13 springs in a no-load state and then turns counterclockwise at a stroke with reception of the elastic force produced after inversion of the spring 20. Thus a cassette engagement member 15 leads quickly a tape cassette 12 into a prescribed position of a cassette holder 9. Thus the cassette inserting force can be reduced.

Title: Common memory control system
Inventor: IKOMA TATSURO
IPC: G06F9/46
Filed: 1988-10-25
Abstract: PURPOSE:To prevent a common memory from lacking due to the acquisition of large capacity of the common memory by a conventional partial task by registering the maximum size to be used in each task using the common memory and restricting the size by the data reference side. CONSTITUTION:A task receiving data from another task by using the common memory 100 stores the maximum capacity of the common memory to be pos sessed to refer to data from the other task in a common memory control area 102. A 2nd task to transfer data to a 1st task transfers the identifier of the 1st task and the necessary size of the common memory 100 to a common mem ory control means 101 and requests the allocation of the common memory 100. The means 101 extracts the possessed size of the common memory 100 and the maximum capacity of the common memory 100 to be possessed from the area 102, and when the sum of the requested size of the common memory 100 and the current possessed size of the common memory 100 exceeds the maximum value, the request is rejected. Consequently, the common memory can be prevented from lacking.

Title: Fluorescent lamp for color image display device
Inventor: IWAMA KATSUAKI
IPC: H01J61/35
Filed: 1989-10-16
Abstract: PURPOSE:To restrain lowering of the light transmittance of a front plate so as to realize a good luminance maintaining characteristic of a fluorescent lamp by forming thin films of ZnO and TiO2 on both side faces of the front plate constituting a light emitting portion. CONSTITUTION:On that face of the translucent front plate 2 of a sealed container main body 1, a thin film of ZnO is formed, and a thin film of TiO2 is formed on that face of the front plate 2 which is exposed to electric discharge. On that face of the front plate 2 which is exposed to fresh air, precipitation of soda is therefore prevented from occurring due to ultraviolet radiation of soloar light and moisture adsorption, while that face of the front plate 2 which is exposed to electric discharge is prevented from becoming dense mainly because of impregnation of mercury. Lowering of the rate of light transmission that progresses on both side faces of the front plate 2 during lighting of a fluorescent lamp is thus prevented to realize a good luminance maintaining characteristic of the lamp.

Title: Manufacture of single crystal alumina
Inventor: KOBAYASHI SADAJI
IPC: C30B29/20
Filed: 1984-12-20
Abstract: PURPOSE:To manufacture the titled good-quality single crystal alumina in high yield by manufacturing the alumina single crystal by a flame fusion method from raw material powder consisting of gamma-alumina obtained by calcining a specified composition. CONSTITUTION:Alumina single crystal is manufactured by the Verneuil's method (a flame fusion method) from alumina raw material powder consisting essentially of alumina and obtained by calcining a composition shown by the formula at 400-1,000 deg.C. The composition shown by the formula is manufactured, for example, by allowing an aq. soln. of ammonium bicarbonate to react with an aq. soln. of ammonium alum. The calcination is carried out selectively at 400-1,000 deg.C, because gamma-alumina, which is effective when the single crystal alumina is manufactured by the Verneuil's method, is obtained in high yield by calcination or thermal decomposition in the temp. range 400-1,000 deg.C.
