Patent JP-H0984368-A (JP)
Title: Piezoelectric motor
Inventor: ISOBE JIRO
IPC: H02N2/00
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce the number of drive parts and make the operations of all piezoelectric elements the same by forming teeth with equal intervals along the circumference of a rotating element, and disposing the drive parts along the circumference. SOLUTION: The direction of the expansion/contraction of a drive part 21, or the direction of force applied to the tooth of a rotating element 11 from the drive part 21 is roughly equal or next to the connecting direction in the outer circumference of the rotating element 11. When the direction of the expansion/contraction of the drive part 21 is brought the normal direction of the rotating element 11, or the direction of the expansion/contraction of the drive part 21 is brought near the center of the rotating element 14, the direction of force applied to the tooth of the rotating element 11 comes near the center of the rotating element 14, thus increasing the rotational speed of the rotating element 11. The required amplitude of a leaf spring 51 also decreases.  By applying a.c. voltage to the piezoelectric element, it is possible to eliminate the residual strain of the piezoelectric element and increase stress on the piezoelectric element at a time with no residual strain, thus increasing the rotational speed of the piezoelectric element.

Abstract: PURPOSE:To quickly perform the read-in processing of a source file by referring to a multi-byte code existence identifier to discriminate the presence/absence of character data of a multi-byte code in each text record at the time of the read-in processing of the source file. CONSTITUTION:Text records 10 each of which has a multi-byte code existence identifier 11 where data, which indicates whether the text record includes character data of a multi-byte code or not, is recorded are stored in a source file 1 and if the text record 10 stored in the source file 1 includes character data of the multi-byte code, a source file output means 2 records this inclusion in the multi-byte code existence identifier 11 and outputs the text record 10 to the source file 1.

Abstract: PURPOSE:To contrive an improvement in workability by performing automatically control of negative pressure without assistance, by a method wherein at the time of coating of an unusual outer diametral part with resin, a resin coating and extruding machine is controlled so that the negative pressure of the same is released and after the unusual outer diametral part is passed through the resin coating and extruding machine, control is performed under a state where resin coating is performed by applying the negative pressure to the title hose as usual. CONSTITUTION:A wound up blade hose 1 is unwound in order and an outer circumferential surface of the blade hose 1 is coated with cover rubber by a rubber extruding machine 2. Then the same is compared with a pre-established hose outer diameter by detecting the same in order by an outside diameter measuring apparatus 3 and an unusual outer diametral part, that is, a thin part of the outside diameter of the hose or a joint part of the hose is detected. With this construction, at the time of coating of the unusual outside diametral part of a rubber hose main body W with polymethyl pentyl resin, control is performed so that negative pressure of a resin coating and extruding machine 5 is released and a resin coating of the unusual outside diametral part is completed. Then at the time of coating of the normal outside diametral part with polymethyl pentene resin, coating of the polymethyl pentene resin is performed under a state where the negative pressure is applied again to the hose.

Title: Virtual storage system
Inventor: OKADA TETSUHIKO
IPC: G06F12/10
Filed: 1986-11-14
Abstract: PURPOSE:To decrease the quantity of data saved into a stack and also to reduce the overhead applied to the fault exceptional processing, by using an exceptional state register, a state register, a program counter, etc. CONSTITUTION:When a processor executes a machine instruction to transfer the data of a long word (4 bytes) stored in a register to a main memory, the values of a program counter PC170 and a state register SR260 which are set before the machine instruction is carried out are saved. Then the transfer of data is started after an IC flag contained in an exceptional state register ER250 is set at 1 in case a page fault occurs in a store step in the latter half of data. In this case, the page of a transfer destination address is stored in the main memory in a fault exceptional handler routine. Thus the data transfer processing is through normally and the execution can be continued via the PC170 and the SR260 as if no exceptional processing were caused. Then it is possible to decrease the quantity of data saved into a stack and to reduce the overhead applied to the fault exceptional processing.

The lower- side main surface of the other end section of the external leading-out conductor 4 is projected from the surface of the sealing substance 3. Accordingly, even when external force is applied to the other end section of the external leading- out conductor 4, the other end section is fixed by the sealing substance 3, thus preventing deformation.

Although aq. soln. of salt of chloroiridic acid has been obtd. in the prior art by extracting with water a soluble salt such as Na3IrCl6, etc., after treating Ir powder with NaCl or BaCl2 while heating in Cl2 gas atmosphere, removal of Na<+> or Ba<2+> by ion exchange, etc., has been necessary for the prepn. of pure H3IrCl6, moreover the yield of the prior process was inferior. H3IrCl6 is prepd. by dissolving Ir almost quantitatively and with a relatively simple procedure in accordance with the process of this invention.
