Title: Pipe joint
Inventor: TAKAMURA TSUYOMICHI
IPC: F16L21/08
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a pipe joint to prevent leakage and stably show a predetermined loosening stop force by ensuring a pushing amount of packing by pushing rings. SOLUTION: When pushing rings 4 are tightened and connected to a pipe joint body 2, lock rings 5 are abutted against retainers 7 and disposed at a predetermined position, packings 6 are pushed into spreading diameter portions 3a by a predetermined amount and then the packings 6 are diametrically reduced by inner taper faces 4a of the pushing rings 4. Accordingly, there is no fear for leakage, caused by a shortage of the pushing amount of the packing 6. Further, a loosening stop force is stabilized since the lock rings 5 are diametrically reduced at a substantially fixed position.

Title: Correction system for read image data
Inventor: NAKAMURA TOSHIAKI
IPC: G06T5/00
Filed: 1987-06-17
Abstract: PURPOSE:To eliminate influence of a noise amid a read action and of a bit- lacking by obtaining the density difference between a picture element and the two picture elements in its both neighborhood in the dimain scanning direction, and making the density of the picture element be the average of the densities of the neighboring tow picture elements if the difference is above a certain value. CONSTITUTION:In the case of image data read by a sensor with resolution of >=8 dot/mm in the main scanning direction, In case image data B has a large level difference to data A and also to C, it is considered that data B is bit-lacking or influenced by a noise mixed during the read action. So, when the level difference is decided to be exceeding a threshold set in a register 9 by decision circuits 4, 5, the average value of the A and C, instead of that of the B, is outputted from an average circuit 7 to a selector 8. In such a way, the influence of a noise and a bit-lacking can be eliminated.

Title: Disk device having fixed surface memory density
Inventor: NISHIKAZE KAZUHIKO
IPC: G11B25/04
Filed: 1983-08-15
Abstract: PURPOSE:To attain an apporximately fixed level of memory density by increasing the angle between the direction of an input/output head and the direction vertical to the revolving direction of a disk as the scanning of the head gets close to the outer circumference of the disk. CONSTITUTION:The slit direction of the input/output part of a head is generally and usually equal to the direction a disk is going toward centripetal. It is impossible with this scanning method to fix the surface memory dinsity. Therefore the angle is increased between the slit direction and the centripetal direction of the disk as the scan of the head gets close to the outer circumference of the disk. Thus the memory density is reduced toward the outer circumference of the disk and set at nearly a fixed level. This improves the characteristics of a disk device.

IPC: F24F1/00
Filed: 1977-12-12
Abstract: PURPOSE: To comfortably heat by a hot air heater with a dust collector by switching an ignition high voltage circuit thereof to a dust collector contained internally and externally in the body thereof except for ignition time to thereby drive the collector so as to clean the air in the room.  
     CONSTITUTION: When an AC voltage is applied between terminals 1 and 1', a charging current flows through a capacitor 12 via a diode 11, the contact (b) of a switch 10, primary winding of a transformer 14, and a resistor 13. When the voltage across the terminals of the capacitor 12 reaches the breakover voltage of a Sidac 15, the Sidac 15 turns ON with the result that it is discharged through a closed circuit of the capacitor 12, Sidac 15, the primary winding of the transformer 14, and the switch 10. When this discharging current flows instantaneously through the primary winding of the transformer 14, high voltage is generated through the secondary winding thereof to thus discharge between discharge electrodes 18. After the ignition is completed, the switch 10 is changed over to the contact (a) side to form a high voltage generating circuit for a dust collector commonly with the ignition high voltage generating circuit.
