Title: Manifold for changeover valve
Inventor: YOSHIMURA SHINICHI
IPC: F16K27/00
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To provide a manifold for changeover valve which can change over a pilot changeover valve to be arranged between inner pilot type and outer pilot type. SOLUTION: A valve box 10 having a high pressure preference shuttle valve 11 is arranged on an upper surface of a manifold 1 having a longitudinal pressure fluid supply passage 4, discharge passages 5A, 5B and a common pilot supply flow passage 6. An internal pilot supply flow passage 8 communicating with the supply flow passage 4 and an external pilot supply flow passage 13 communicating with external pilot ports X1, to X4 are opened inside a valve chamber 12 of the shuttle valve 11 while being faced to each other. An outer peripheral surface of the valve chamber 12 communicates with the common pilot supply flow passage 6. When the pressure of the fluid inside the internal pilot flow passage is higher thn that inside the external pilot supply flow passage, the inner pilot fluid is supplied into the common pilot supply passage 6 from the shuttle valve 11.  In the contrary case, the outer pilot fluid is supplied to the common pilot supply flow passage 6. A pilot changeover valve 2 can thus be changed over between inner pilot type and outer pilot type.

Patent JP-H06167854-A (JP)
Title: Image forming device
Inventor: USUI NORIYUKI
IPC: G03G15/08
Filed: 1992-11-27
Abstract: PURPOSE:To prevent deterioration of image quality, which results from resticking of residual toner to an electrostatic latent image by, prior to the formation of an original electrostatic latent image, forming a latent image pattern for making toner, remaining on a photosensitive body at the time of separating a cleaning blade from the photosensitive body, and sticking to a sealing member at the time rotating the photosensitive body, electrostatically shift to the photosensitive body. CONSTITUTION:When the cleaning blade is separated from the surface of the photosensitive body 1 after an image forming operation, toner remains in line shape on the photosensitive body 1. Also, when an image forming operation is started and the photosensitive body 1 is rotated, the residual toner on the photosensitive body 1 stickes to the sealing member of a development device. Therefore, prior to the formation of the original latent image 7 on the surface of the photosensitive body 1, the latent image pattern 21 is formed upstream on the surface of the photosensitive body 1, thereby electrostatically shifting the toner sticking to the sealing member to the latent image pattern 21. As a matter of course, the toner sticking to the latent image pattern 21 is removed from the photosensitive body by a cleaning device without being transferred to transfer paper.

Title: Carrier suppression feedback circuit
Inventor: FUNAKUBO TOSHIAKI
IPC: H04L27/20
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To enhance detection accuracy of magnitude of a carrier leakage by controlling the phase and the amplitude of a 2nd carrier output, so as to maximize the output of a difference between detection levels of output levels of an orthogonal modulation means detected respectively by 1st and 2nd detection means. SOLUTION: An adder 7 combines a carrier cancel signal received from a level adjustment device 4 and an output of an orthogonal modulator 1 and transmits a combined output. A level detector 5 detects the output level of the orthogonal modulator 1, and a level detector 5 detects a level of the synthesized output. A subtractor 8 calculates the difference between the detected outputs by the level detectors 5, 6. The subtractor 8 gives an output including a modulation signal component that is zero and the difference between carrier leakage signals required for control to a gain setting section 9 and a phase setting section 10. The gain setting section 9 and the phase setting section 10 adjust a 180-degree phase shifter 3 and the level adjustment device 4 so as to maximize the output level of the subtractor 8.  Thus, the adder 7 can transmit the modulation signal where the carrier leakage components are cancelled.

Abstract: PURPOSE:To enable judgment of a tip part or the like contacting an object to be inspected regardless of a curvature value of a bend by detecting the curvature value of the bend and a bending resistance to tell a condition when the bending resistance exceeds a specified value corresponding to the curvature value. CONSTITUTION:A bend manipulation wire 37 is so arranged that a deflection of another chain 33 is read by a retrieval with a bending piece at the tip thereof. An encoder 27 connected to a connecting shaft 25 outputs the rotation of a drive motor 23, for example, as pulse signal, which is inputted into a curvature value detection unit 51 to detect a curvature value of a bend 16. The bending wire 37 has a bending resistance detection plate 39 having a strain gauge 41 stuck thereon interposed therein and as the bend wire 37 is hauled, a kinematic value thereof is inputted into a bending resistance detection unit 52 as electrical signal to detect the bending resistance. The curvature value and the bending resistance detected are inputted into a comparison/computation unit 54 to judge that the bending resistance exceeds a value which is expected naturally to be given by a bending. When it exceeds the value, an operator is informed of the condition by emission of an indicator of a monitor 5.

Abstract: PURPOSE:To correct an initially set bath-preparation time and make the bath ready at reserved time by circulating remaining water in a bathtub before predetermined period of reserved time if the remaining water is contained in the bathtub, and detecting the temperature of the remaining water. CONSTITUTION:When water 25 in a bathtub is raised to a position of an adapter 20, the output of a water level sensor 17 is raised. When a predetermined water level is raised, a circulation mode is started, and a return tube 24 is filled with water. When the mode is ended, hot water is again supplied. When a set water level is obtained, the mode is again started. If the hot water temperature is lower than the set hot water temperature, a burner is additionally burned to heat the water. The water supplying quantity QT to the set water level and boiling-up time TA are stored in a memory circuit. Since the time from the start of automatically supplying hot water to the boiling-up is TA, if the quantity QT is detected by a water quantity sensor Q, the boiling-up is completed at the reserved time if the TA is employed when remaining water is not contained in the bathtub next time. If the remaining water is contained, the remaining hot water quantity is calculated by the hot water temperature rise per unit time, the time of additional hot water supplying amount is added so as to boil up at the set time.
