Title: Predictive coding system
Inventor: HACHITSUKA YOUTAROU
IPC: H04B14/06
Filed: 1978-09-01
Abstract: PURPOSE:To prevent the quality deterioration of the signals to be shown to the high band frequency signals as well as to avoid the increment of the bit number by means of the predictor set to the low band frequency in case the predictive coding is given to the digitized signals. CONSTITUTION:Frequency measurement unit 8 and polarity controller 9 are provided between input terminal 1 and subtractor 2. Then the input digital signals are divided into the unit blocks which are a series of sample value groups of the fixed number, and a decision is given whether the information within the blocks are drifted toward the high band frequency. And after detecting the blocks having the drifting, the polarity control signals are delivered to polarity controller 8 and control terminal 10. The polarity controller gives inversion to the polarity of the sample value of the blocks drifted toward the high band with every second units and then transmits it to subtractor 2 via the output given from frequency measurement device 9. As a result, the frequency is shifted to transfer the high band distribution to the low band. At the reception side, the reverse conversion is given to the quantization level corresponding to the code word through reverse quantizer 12, thus carrying out the decoding.

Title: Trolley line ice and snow remover
Inventor: OBARA TADASHI
IPC: B60M1/12
Filed: 1981-07-08
Abstract: PURPOSE:To safely and readily remove ice and snow by Joule heat which is produced by short-circuiting trolley lines for feeding current to a travelling vehicle therethrough when ice and snow are to be removed, by connecting a power feed controller provided with a change-over switch to one end of each of the trolley lines and a trolley line short controller to the other end. CONSTITUTION:For removing ice and snow which are stuck to and accumulated on trolley lines 1 in winter or other cold weather, a change-over switch 7 is changed over to close a limit switch LS. A no-fuse breaker 11 is then thrown in before an ice and snow removal starting push-button switch 13 is turned on, so that electro-magnetic contactors 10, 17 are excited. Since normally opened contacts 10a1-10a3 and 17a are closed, the electro-magnetic contactor 10 holds itself and an on-delay timer 14 is excited to short-circuit the trolley lines 1. On the other hand, a power is supplied from a power supply via a terminal 5, a power supply convertor 9 and a terminal 8 to the trolley lines 1, that is, a current flows through said trolley line in the form of a short-circuit current, thereby generating Joule heat by the internal resistance aganist the current to melt the ice and and snow. there is a lapse of a certain period before a contact 14b is opened to complete the removal of the ice and snow.

Title: Form folding method in copying machine provided with bookbinding function
Inventor: ISHIKAWA MASAHIRO
IPC: G03G15/00
Filed: 1984-05-28
Abstract: PURPOSE:To form a fold after carrying a form exactly, and to execute efficiently saddle stitching bookbinding by forming the fold so as to be orthogonal to the carrying direction of the form, in the center part of the form. CONSTITUTION:A form folding part 45 is provided on the downstream of a fixing part, and a missing periphery roller 49 is placed so as to be joinable in a carrying roller 47. Also, sponge rollers 51, 51, a form detecting sensor 53, stopper 54 which can move forward and backward freely, etc. are provided on a path 50. A form which has passed through the fixing part goes into the folding part 45, abuts on the stopper 54 and stops temporarily; but in that case, the form starts to bend in the direction of a joint part at the end of the path 50 by a feed action of the rollers 47, 48. In this case, the sensor 53 detects the form and brings the missing periphery roller 49 to one rotation, a fold is formed by the rollers 47, 49, and the form is fed to a stitching part. Therefore, the form is carried exactly, the fold is formed, and saddle stitching bookbinding can be executed easily.

Title: Control circuit of constant-speed running device for car
Inventor: KURIHARA KATSUMITSU
IPC: B60K31/00
Filed: 1987-04-30
Abstract: PURPOSE:To provide smooth constant-speed running condition by generating an initial acceleration control signal which is increased from a normal acceleration control signal to drive the actuator to the acceleration side when the car is to be accelerated immediately after completion of sensing signal generation for the decelerative operating limit of the actuator. CONSTITUTION:When running on a down slope, a control lever 26 is at decelerative operating limit, and a throttle valve 27 is in opened condition, so that play is generated on a throttle wire 28. When a flat course is encountered after running on a long down slope, the car speed is sunk below the set value because the throttle valve 27 is fully closed. To restore the car speed to the set level, a magnet clutch 24 is again put in engagement, and an acceleration signal is given to the motor 25. With a signal for absorption of play of the wire 28 added to this output, the CPU 7 emits an initial accelera tion signal strengthened from normal acceleration signal corresponding to decrease of the car speed according to the set car speed. Therefore, the car speed is controlled smoothly without causing drop to a great extent.

IPC: H01L27/14
Filed: 1982-06-23
Abstract: PURPOSE:To simplify stages in the stage of making mosaic filters of cyan, yellow and green by a number of stages of printing and exposing by using the cyan filter itself as an original plate and printing the megenta part with said filter. CONSTITUTION:Cyan stripes are formed on the surface of a filter base plate by dyeing a printing photoreceptor to a cyan color. A magenta stripe is printed on the rear of the filter substrate by using said cyan part as an original plate. The cyan part cuts thoroughly UV light so that the UV part of the light source for printing does not transmit the base plate. Yellow stripes are printed and dyed so as to intersect orthogonally with both stripes. In the end, the filter is fully embedded with the mosaic of yellow-2, cyan 1, magenta yellow 3, magenta 4 and green. A color camera is constituted of such filter and a single tube image pickup tube.

IPC: F15B15/26
Filed: 1993-05-07
Abstract: PURPOSE:To provide a fluid pressure cylinder with no projection outside of a cylinder case based on a fall preventing device without enlarging the cylinder case itself so as to attain compactness and save space. CONSTITUTION:A groove 16 is formed at the inner peripheral wall of a cylinder case 1 (2, 3), and a retainer ring 18 is fitted into this groove 16. Plural balls 19 are then fixed to the retainer ring 18 to form a fall preventing device 15. When a piston 4 is positioned at the ascent end, the balls 19 are engaged with a ring groove 22 formed at a piston rod 6 by the resilience of the retainer ring 18 in its diameter contracting attempt so as to prevent the piston 4 from falling by its own weight. There is thereby no need to enlarge the cylinder case 1 (2, 3) in order to provide the fall preventing device 15, nor is the fall preventing device 15 protruded outside of the cylinder case 1 (2, 3).

Abstract: PURPOSE:To reduce the size of permanent magnet by coupling an anode cylinder and an auxiliary anode cylinder through an annular metal shield while electromagnetically coupling an inner conductor for leading out the electromagnetic wave arranged on the inner face of anode cylinder with an outer conductor along the innercircumferential face of an insulation ring. CONSTITUTION:An inner conductor 10 for leading out the electromagnetic wave extending from an anode vain 9 projecting to the inner face of anode cylinder 1 will round along the innercircumferential face of an insulation ring 3 to take out the electromagnetic wave produced through oscillation to the outercircumferential face side of the insulation ring 3 via said conductor 10. The annular metal shield 11 convering an outer conductor 12 for leading out the electromagnetic wave arranged along the outercircumferential face of said ring 3 without contact has C-shaped cross-section to couple between the anode cylinder 1 and the auxiliary anode cylinder 4. One end section of the outer conductor 12 is led out through a hole 13 made through the metal ring 11 thus to take out the electromagnetic wave output to the outside. Consequently, the axial length can be shortened resulting in perfect permanent magnet, reduction of diameter and improvement of excitation efficiency.
