Title: Method for obtaining circumference length of object by picture processor
Inventor: KAWAKUBO MITSURU
IPC: G06T7/60
Filed: 1987-10-07
Abstract: PURPOSE:To detect the circumference length of an object at high speed by providing plural change point detecting circuits, etc., and calculating the circumscribing length in the X axis direction of the object, the circumscribing length of a Y axis direction and the number of edges at a high speed in parallel while a binary picture signal is fetched. CONSTITUTION:A change point detecting circuit 5 detects the change point between the black and white of an input binary picture signal (present line data), counting is executed by a Y-perim counter 3 and the circumscribing length of the Y axis direction of the object of a white picture is stored. An X-perim counter 2 counts the pixel clock when the output signal (previous line data) of one line delaying circuit 1 to delay one line of the binary picture signal and an XOR signal of the present line data are turned on, and the circumscribing length of the X axis direction of the object of a white picture is stored. An edge counter 4 counts a pixel clock when the XOR signal of the output signal of the circuit 5 and the output signal of a change point detecting circuit 6 of the previous line data is turned on, counts the 1/2 of the number of the edges of the object of a white picture and therefore, the circumference length of the white picture object can be detected at high speed.

Title: Damper damping vibration of valve controlled by pressure fluid
Inventor: TORUKIRUDO KURISUCHIENSEN
IPC: F15B21/045
Filed: 1988-10-05
Abstract: PURPOSE: To stabilize rapidly an initial oscillation by providing a throttle with a throttle gap of which the height varies oppositely to the temperature of the pressure fluid. CONSTITUTION: Throttles 13, 14, 16, 19, 20 each comprises a rod 22 and a housing 24. A thermal expansion coefficient αA of the rod 22 is greater than a thermal expansion coefficient αS of the housing 24. Therefore, since a throttle gap 28 has a height h varying oppositely to the temperature of the pressure fluid so as to compensate fully or partially for changes in the hydraulic resistance K that are occasioned by the temperature, the throttle gap 28 is mostly traversed by a laminar flow. Consequently, there is a high hydraulic throttling resistance even at low speeds of flow, so that small oscillations of the valve element can be damped effectively thus rapidly stabilizing the initial oscillations.

Title: Plate group welding tool of lead-acid battery
Inventor: OGUMA MIKIO
IPC: H01M50/536
Filed: 1983-12-26
Abstract: PURPOSE:To surely weld weak and thin plates and make welding process automatic by narrowing width of the teeth of a lower comb than that of the teeth of an upper comb in the comb of a double structure which is slidable, and installing projections on the upper side of the lower comb. CONSTITUTION:A plate group welding tool is formed in a double structure of an upper comb 8 and a lower comb 8', and triangle projection 10 is formed on the upper side of each teeth-of-comb 9 of the lower comb 8. By stacking the upper comb 8 and lower comb 8', the projection 10 of the teeth-of-comb 9 of the lower comb 8' is closely contacted to the side of the teeth-of-comb 11 of the upper comb 8. Since the width W2 of the teeth-of comb 9 is narrowed than the width W1 of the teeth-of-comb 11, when the upper comb 8 is slided along the contact surface, groove width is widen from a to b. Thereby, the tool is opened and closed without giving any damage to lugs of the plates. When welding the plate group, since the width of groove is narrowed to decrease a gap to lugs, dimension accuracy of a strap finished is increased.

Title: Wire cut electric discharge machine
Inventor: INOUE KIYOSHI
IPC: B23H7/04
Filed: 1987-10-06
Abstract: PURPOSE:To prevent the occurrence of one-point concentration discharge, by a method wherein energizers to feed a machining pulse are situated in a manner to make contact with wire electrodes on the upper and the lower side of a workpiece, and pulse sources for machining being independent from each other are situated to the respective energizers. CONSTITUTION:A machining liquid flow in a on-way is formed by a high pressure velocity of flow through a lower nozzle 52 and a low pressure jet through an upper nozzle 51. With this state, a switch 81 is made and broken by means of a gate pulse generating circuit 10 to feed a discharge pulse from a power source 71 through a resistor 91 and from an energizer 61 between an electrode 1 and a workpiece 4. With a pulse generating circuit 11 actuated, a switch 82 is made and broken, and a pulse current is fed from a power source 72 through a resistor 92 and from an energizer 62. As noted above, since a non- synchronous pulse current is fed from the upper and lower energizers, one-point concentration discharge is prevented from occurring, production of gas due to an overcurrent is prohibited, and disconnection of a wire electrode due to heating is prevented from occurring, resulting in the possibility to improve a machining speed.

Title: Image pickup tube
Inventor: NAGASAWA TOMONORI
IPC: H04N5/228
Filed: 1984-11-29
Abstract: PURPOSE:To reduce the parts not scanned even in over-scanning, by causing defocus state by varying the average level of deflection signal during blanking periods when overscanning is carried out. CONSTITUTION:During blanking the unscanned part 3B surrounding the effective scanned part 3A of the target face 3 of the image pickup tube is scanned (over scanning), and generation of framing and electrode reflection image are prevented by discharging of the electric charge of the unscanned part 3B. In performing overscanning, the average level VGW(HGW) of the deflection signal EV (or EH) during the period of blanking shall be altered. Then, the electron beam Bm during overscanning shall be in defocus state and the width shall be expanded. Thus, even if rough scanning is carried out in the overscanning area, hardly any part remains unscanned, and the effects of overscanning is amply demonstrated.

Title: Fuel injection controller of diesel engine for vehicle
Inventor: ITO YOSHIYASU
IPC: F02D41/04
Filed: 1991-09-30
Abstract: PURPOSE:To improve acceleration, and to prevent second slip by having an output torque started immediately when the amount of injection is increased after first acceleration slip. CONSTITUTION:A fuel injection controller is provided with a fuel injection pump 1 and various sensors 35, 73, 74. The amount of fuel injection is calculated by a CPU based on the detection results of the sensors, and when the amount of fuel injection is changed, the actual amount of fuel injection is corrected so that the amount of fuel injection before the change becomes gradually closer to the amount of fuel injection after the change. When acceleration slip of a driving wheel occurs, the calculated amount of fuel injection is reduced and corrected by the CPU according to the acceleration slip, to reduce the amount of injection. The gradually changing/correcting operation in the amount of injection is inhibited by the CPU for increase in the amount of fuel injection when the amount of acceleration slip is reduced, and the amount of reduction correction is reduced.

Title: Image reader
Inventor: NISHIMURA SHINICHI
IPC: H04N1/407
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To appropriately correct the black side of an output signal from a line image sensor by preserving a value closest to a black level for each pixel among the respective pixels outputted from the line image sensor. SOLUTION: The image signal of a 1st line provided by reading a black reference plane through a line image sensor 11 is preserved via a register 13 and a switch 16 to a line buffer 17. For the same pixel position of the line image sensor 11, a comparator 15 compares a signal DP1 of the image signal read at that tame point with a signal DP2 of a black reference signal DPb which is preserved in the line buffer 17. When the signal DP1 is smaller than the signal DP2 (much closer to the black level), a signal SL is set at a logic H level. The switch 16 selects the signal DP1 and outputs it to the line buffer 17. The value of the black reference signal DPb at such a pixel position is updated to the value of the signal DP1 much closer to the black level.

Title: Air-conditioning device
Inventor: KURACHI MASAO
IPC: F25B13/00
Filed: 1989-09-27
Abstract: PURPOSE:To prevent a compressor from being interrupted in its operation upon starting heating operation by providing a heat source side refrigerant cycle and a utilization side refrigerant cycle, and further providing a control device for opening a solenoid valve disposed in parallel to a heating pressure reducing device by pressure detected by a pressure detector device in the heat source side refrigerant cycle. CONSTITUTION:Much gas refrigerant mixes into the inlet side of a refrigerant carrier device 11 upon heating operation to reduce the amount of heat exchange in a second auxiliary heat exchanger 9 is lowered and hence high pressure in a heat source side refrigeration cycle rises. Once the high pressure reaches predetermined pressure, a pressure detector device 14 is actuated to cause a control device 15 to open a solenoid valve 13. Accordingly, the amount of pressure reduction is lowered to acuse the amount of exchanged heat (amount of heat absorption) of a heat source side heat exchanger 3 to be lowered and hence the amount of exchanged heat (amount of heat dissipation) in a first auxiliary heat exchanger 8 to be reduced. Hereby, a compressor is prevented from being interrupted even though capability of the refrigerant carrier device is lowered upon the starting of heating operation.

Abstract: PURPOSE:To reduce the capacity of a memory and to shorten a processing time by providing data supply means which supply position data on the position of a change point to the data input terminal of a memory and writing means which write the position data on the memory when the change point is detected. CONSTITUTION:Change point detecting means 11 and 12 which detect the change point of a binary image, data supply means 6 and 7 which supply position data on the position of the change point to the data input terminal of the memory 5a, and means 13-15 which write the position data on the memory when the change point is detected are provided. The memory is stored with the change point of image data, i.e. only an edge and the number of bits required to store one change point increases, but the number of picture elements of the change point is much less than the total number of picture elements, so the number of bits required to store all change points is less than the number of bits required to store all picture elements. Consequently, data which are processed by a computer decreases in number greatly and the processing time of the computer is shortened greatly and the capacity of the memory is decreased.
