Title: Electric heater
Inventor: MATSUMOTO TOSHINARI
IPC: H05B3/00
Filed: 1989-04-28
Abstract: PURPOSE:To prevent re-feeding of current to a heater by feeding the current to one side of a timer circuit from a controller through turning of a control knob, actuating a start switch temporarily by a boss by means of further turning, thereby feeding current to the other side of the timer circuit so as to shut the contact of a relay. CONSTITUTION:Turning of a control knob 13 actuates a controller 12 to cause current feed to a timer circuit 15 from an output terminal 16, and further turning of the same knob 13 actuates a start switch 19 by a boss 14 temporarily to cause current feed to the other side of the timer circuit 15, and thus the contact of a relay 17 will be shut. Now the timer circuit 15 continues operating, and the contact of the relay 17 is opened after passage of a certain period of time so as to stop current feed to the timer circuit 15 and a heater 11. Even though power failure, etc., interrupts current feed for a certain time and that is followed by re-feeding, there is no risk of current being fed again to the timer circuit 15.

Title: Image forming device
Inventor: MASUDA JITSUO
IPC: G03G15/00
Filed: 1987-05-01
Abstract: PURPOSE:To remove only defective toner in a developing device by driving an opposite- polarity electrostatic charging means which charges the no-image formation area on the surface of a photosensitive body to a potential which is opposite in polarity from the potential for the formation of an electrostatic image every time an image forming process is performed by prescribed times. CONSTITUTION:A counter counts how many times the image forming process is performed and when the contents of the counter reach a prescribed number A, an opposite-polarity charger 1 is driven for the no-image formation area on the surface of a photosensitive drum 2. The no-image formation area of the photosensitive drum 2 is changed electrostatically to the potential which has the same polarity with the potential of normal charged toner attracted to the electrostatic latent image and when the no-image formation area on the photosensitive drum 2 faces the developing device 5 next, the normal toner repels the surface of the photosensitive drum 2. Defective toner which is charged electrostatically to the potential having the opposite polarity from the electrostatic charging potential of the normal toner is attracted to the no-image formation area on the photosensitive drum 2 and scraped off. Consequently, only the defective toner generated in the developing device can be removed and its image quality is improved.

Title: Magnetic disk driver
Inventor: SANBE TOORU
IPC: G11B17/028
Filed: 1982-06-28
Abstract: PURPOSE:To obtain a miniature magnetic disk driver which is capable of stable and high-speed revolutions, by applying an outside rotor type structure to a magnetic disk driving motor and therefore using the outside rotor itself as a ratory shaft after fixing a magnetic disk directly to the outside rotor. CONSTITUTION:An outside rotor type driving motor is applied to a magnetic disk. A coil 8 is wound round a stator 7 which functions as a center shaft. The poles N, S, N and S are successively magnetized in the circumference direction of an outside rotor 6, and the flowing direction of current to the coil 8 is switched to revolve the rotor 6. Magnetic disks 1, 2 and 3 are revolved together with the rotor 6 since they are fixed to the rotor 6. In this example a magnetic disk driver can be miniaturized since the driving motor is incorporated into the center shaft. For a magnetic disk, a small radius of the inner circumference is generally used in terms of the magnetic characteristics. This causes especially no reduction of storage capacity. Furthermore the stable and high-speed revolutions are obtained for a magnetic disk since the driving force is transmitted directly to the disk.

Title: Stopper-fixing method and device therefor
Inventor: KARIYA KIYOSHI
IPC: B31B1/84
Filed: 1990-04-25
Abstract: PURPOSE:To enable a stopper to be welded to a vessel, while heat is generated at the boundary surface between the stopper and the vessel by a method in which the stopper is temporarily fixed to the vessel, and the vibration energy of ultrasonic wave is applied is parallel to any one contact surface of the vessel and the stopper through a vibration resonant body. CONSTITUTION:The ultrasonic wave vibration-direction (direction C) of a vibrating horn 17 is made parallel to the contact surface of a vessel 1 and a stopper i.e. to the extending direction of a stopper-brim 5 and a hole-covering part 9. Accordingly, the longitudinal wave-vibration from a vibrating horn 17 is not transmitted directly from the rectangular direction to the stopper-brim 5 and the hole-covering part 9, and it is transmitted in the state parallel to their extending direction. Consequently, the longitudinal wave vibration is not directly given to the stopper-brim 5 and the hole-covering part 9, whereby so called pin holes do not occur at the part. P in holes are apt to occur especially at thin wall part 8, but such anxiety is removed.

Filed: 1984-05-30
Abstract: PURPOSE:To shorten time for checking data inputting/outputting operation of input/output terminals and to reduce the number of connecting lines by providing scan flip-flop in each input/output circuit unit. CONSTITUTION:Scan flip-flops 35a-35c are provided in each input/output circuit unit (IOU)31, and necessary data are transmitted in series using small number of connecting lines to the flip-flop by scan in system, and distributed one by one by a decoder 34. Increase of time required for transmission in series makes distribution in series of data by scan in system in the second test controlling section 3a during scan in operation timing of the first test controlling section 2 possible by conditional expression of the number of normal data input/output terminals < the number of flip-flops of the object to be tested. Thus, the time for test does not increase by the reduction of the number of connecting lines.

Title: Production of single crystal
Inventor: HASHIMOTO TADANORI
IPC: C30B11/10
Filed: 1982-06-25
Abstract: PURPOSE:To obtain a single crystal which is improved in quality, productivity and yield by using a raw material for a single crystal granulated to a spherical shape in the production of the single crystal by the Bernoulli's method and controlling the falling rate of the raw material powder which falls in an oxyhydrogen flame. CONSTITUTION:Raw material powder for a single crystal which is granulated to a spherical shape is used in the production of a single crystal by the Bernoulli's method. The raw material for the single crystal is granulated to a spherical shape by granulating a slurry consisting of the raw material powder and water or a solvent such as an org. solvent with a spray dryer or fluidized dryer. More particularly the granulation with the spray dryer is preferable with respect to the grain sizes of the resulted granule. If the grain size of the granule is <=5mum, the granule is vulnerable to scattering in the stage of dropping the same in an oxyhydrogen flame and a low yield results therefrom. If the grain size is >=200mum, it takes time for melting the granules after it is once follen into a growth part of a single crystal; therefore, the preferable grain size is 5-200mum.
