Title: Address conversion buffer storage device
Inventor: WATABE YASUO
IPC: G06F12/10
Filed: 1984-02-15
Abstract: PURPOSE:To omit a memory of a real address part of an address conversion buffer and to obtain an economical address conversion buffer storage device by using a comparator comparing a virtual address with a real address obtained after address conversion. CONSTITUTION:A real address found out by an address conversion logic 304 is sent to a main memory device through an address register 305 and a selecting circuit 314. The coincidence between the bits 1-19 of the found real address and bits 1-19 of the virtual address is detected by a comparator 318. When a coincidence signal is outputted from the comparator 218, a writing request is generated to an address conversion buffer 307 in a TLB1 and registered together with a space identifier from a STOID302 and a virtual address from a logical address register 301. Thus, memory of the real address part of the address conversion buffer is omitted and an economical address conversion buffer storage device is obtained.

Filed: 1984-02-15
Abstract: PURPOSE:To facilitate the driving of vibrators, by laminating several sheets of thin vibrators so that the thickness becomes the required thickness, and making electrostatic capacity large even though the diameters of the vibrators are the same and the vibrating frequency is made low. CONSTITUTION:Vibrators 21a, 21b and 21c are piezoelectric ceramics, which are polarized in a poralization direction 28. Vibrators 22a and 22b are piezoelectric ceramics, which are polarized in a polarization direction 29. Bonding surfaces are bonded with electrodes 24a and 24b and electrode 23b and 23c being held in between. Thus, vibrators 31a and 31b for a transducer are constituted. Electrodes 24c and 23a are bonded to both ends of the vibrators 31a and 31b. The vibrators 31a and 31b laminated in this way are fixed to the recesses of a measuring pipe 1 by holding members 33a and 33b. Thus electrostatic capacity can be made large without increasing the diameters of the vibrators 31a and 31b even though an ultrasonic wave frequency is made low. Therefore, driving can be performed without increasing the disturbance of the flow of a fluid and without increasing a dead space.

Title: Method for forming shaft by flat die working
Inventor: AZUMA YOSHIKAZU
IPC: B21H1/18
Filed: 1980-02-29
Abstract: PURPOSE: To form a shaft having the symmetry of revolution rapidly with good yields by sandwiching a blank material between two sheets of flat dies formed with desired shapes on the surfaces thereof, and rolling the material by moving the dies in the direction perpendicular to the blank material axis while strongly pressing the same.  
     CONSTITUTION: A round bar blank material 3 is placed on a stationary die 1 formed with slopes 4, 7 and semicircular projected lines 5, 6. A moving die 2 provided with slopes 8, 9 and semicircular projected lines 9, 10 on the back surface is placed thereon. While the blank material 3 is being strongly pressed with the die 2, the die 2 is moved horizontally in the direction perpendicular to the axis of the material 3. Then, the slopes and projected lines penetrate into the peripheral surface of the material 3, thereby deforming this. This yields the worked droduct 20 formed with chamfers 12, 15 and semicircular grooves 13, 14 by the rolling of the material 3. This working method is possible both hot and cold, and since this permits cold working under small pressing force, its effect is particular high.
