Abstract: PURPOSE:To reduce the amount of hardware of control storage by putting plural arithmetic units in operation by one control storage by using a polyphase clock. CONSTITUTION:A selecting circuit 3 selects an address register 2 to read a microinstruction in an address B(0) of the control storage 4 according to the contents of the address B(0), and stores it in a readout register 5. Then, there is an address B(1) of a microinstruction to be executed next set in the branch address field 8 of the read microinstruction and the address control field 6 is set to logic '1', so the address B(1) to be executed next is stored in an address register 2. The negative output of an address control field 6 is logic '0', so the selecting circuit 3 selects an address register 1 and a microinstruction A(1) stored in an address A(1) of the control storage 4 is read out according to the contents of the address A(1) stored in the address register 1 and stored in the readout register 5.

IPC: B41J2/52
Filed: 1986-07-30
Abstract: PURPOSE:To lower the amount of printing information per unit picture element necessary for representing a plurality of variable density gradations and besides, to increase the speed of processing, by a method wherein the printing information for representing multiple gradations is formed by a bit of gradation differential information and a bit of gradation information and is printed on the basis of those bits of information. CONSTITUTION:As for a printing information editing part 4, a bit of gradation differential information is stored in a gradation differential information storage memory 8 and a bit of gradation information is stored in a gradation information storage memory 10. Then, the contents of the memory 8 are stored in a shift register 12 in each specific amount. A printing data request signal b is outputted to the shift register 12 from a printing part 6 at each picture element. When an output c is '1', the corresponding bit of gradation information in the gradation information storage memory 10 is outputted to the printing part 6 via an output register 14 and the dot printing of variable density corresponding to the inputted gradation information is carried out. When the output c is (O), the bit of stored gradation information is again outputted to the printing part 6 without renewing the contents in the output register 14 and the dot in the same variable density is printed.

Title: Cordless telephone set
Inventor: FUSHIMI SHIGEO
IPC: H04K1/00
Filed: 1989-07-11
Abstract: PURPOSE:To prevent a voice signal in a radio wave from being intercepted by extracting a voice signal from a privacy call signal subjected to compression processing of the voice signal while referencing a reference noise signal and applying expansion processing to the extracted voice signal. CONSTITUTION:A transmission noise signal from a transmission noise generating circuit 13 is added to a voice signal subjected to compression processing by a compression circuit 11 coming from a sender side input terminal 10 at an adder circuit 12. In this case, when the transmission noise signal is sufficiently larger than the voice signal, the output signal becomes a privacy call signal. The transmission noise signal from the privacy call signal from a handset privacy call section 1 is eliminated with an adaptive echo canceller 21 by referencing a reference noise signal in a reference noise generating circuit 23 having the same function as that of the transmission noise generating circuit 13. The compressed voice signal reproduced from the handset privacy call section 1 with the adaptive echo canceller 21 is subjected to expansion processing by an expansion circuit 22 and the result is outputted from a receiver side output terminal 37. Thus, interception in a simple way is prevented.

Title: Water level following submerged pump
Inventor: FUJITA KAZUHIKO
IPC: F04B47/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To precisely adjust height of a submerged pump so as to prevent the submerged pump from being embedded in sedimentation deposit. SOLUTION: A submerged pump main body 11 is floatedly supported on a water level WS while a suction port 11b is sunk in the water by means of a metal can 12, for discharging supernatant water W. Since a suction hose 14 extended from a discharge port 11b of the submerged pump main body 11 has flexibility, this water level following submerged pump 1 is lowered while following up lowering the water level due to discharging accompanied with flexible deformation of the suction hose 14. When the metal can 12 is seated on sedimentary deposit D, the suction port 11b of the submerged pump main body 11 is located higher than the deposit D. The deposit is not discharged together with the water, accordingly.  After the metal can 12 is seated at the deposit D and a draft line DL is lowered to a position of a float switch 13 or lower, the submerged pump main body 11 is stopped by the float switch 13.

Title: Method for setting spacing between end faces of optical fiber
Inventor: WATANABE KAZUNORI
IPC: G02B6/38
Filed: 1983-09-28
Abstract: PURPOSE:To enable setting of the space between the end faces of optical fibers with high accuracy without variance and to enable measurement of the absolute position of the end faces of the optical fibers by detecting the change in bright and dark parts with an image sensor and determining the relative position of the end faces of the optical fibers. CONSTITUTION:Elements 610, 630 at both ends of an image sensor 5 correspond to the positions of end faces 3A, 3B and therefore the relative position and absolute position of the faces 3A, 3B are known by reading and processing the positions from a reference position up to the elements 610, 630 with an arithmetic part. When the end 2A of an optical fiber is inched in an arrow direction in order to decrease the spacing between the end faces 3A and 3B of the optical fibers, a bright part L decreases gradually and the number of the elements in which current flows decreases accordingly. When the number of the elements in which the current flows decreases to 620-630, the number of said elements is processed in the arithmetic part of the sensor 5 and the spacing between the end faces is displayed. The desired spacing between the end faces is obtd. if the movement of the fiber end 2A is stopped at the point of this time.

Filed: 1986-08-01
Abstract: PURPOSE:To prevent abrasion on the tooth surface of a gear, by providing such an arrangement that the tooth surface of a gear having a higher meshing frequency is made of metal which is melted at a temperature lower than that of metal from which the tooth surface of a gear having a lower meshing frequency is formed.

Spiral teeth 3b are formed in the outer periphery of a sleeve 3a made of an aluminum bronze material so as to form a worm gear. The meshing frequency of the worm gear is higher than that of the worm wheel, and therefore, the worm gear is made of aluminum bronze having a low melting temperature. Accordingly, no seizure occurs on the meshed surfaces of gears, thereby it is possible to prevent the tooth surfaces of the gears from being worn.

Abstract: PURPOSE:To always indicate a normal printing action to a printer, by delivering an additional print code from an input/output controller in case the print code delivered from the printer ends with an uncertain print code. CONSTITUTION:In case the final code information of a print data block is set to a function extending code, this extension code is held also at an input register  allotted to an RAM44 within an input/output controller 4. Accordingly, it is  checked as to whether or not the value of the RAM 44 is equal to the extension code after detecting 0 at an output of an output code length register. When  no coincidence is obtained through the above checking, the printing action designated by a device 1 completes. While in case coincidence is obtained, an extension end code is delivered from the controller 4 to a printer 5 via a firmware routine stored in the ROM44. And the information of the extension code set at  the last one of the printing blocks is canceled to complete the printing action  which is designated by the device 1.
