Title: Measuring method for straightness and straightness-measuring apparatus using the method
Inventor: NEGISHI MASATO
IPC: G01B11/30
Filed: 1994-06-09
Abstract: PURPOSE:To highly accurately measure a straightness of a moving mechanism by splitting a luminous flux from a light source means to two luminous fluxes, inverting one of the two luminous fluxes in a vertical and a horizontal directions and synthesizing the luminous flux with the other luminous flux. CONSTITUTION:A laser beam 6 from a lens 5 is guided to a beam splitter 7 as a light-splitting means and divided to two beams, namely, a transmitting beam 8 and a reflecting beam 9. The beam 8 of the divided beams is reflected at a reflecting mirror 11 and then at the splitter 7. The other beam 9 is reflected at a reflecting mirror 13 to pass through the splitter 7. The other beam 9 is thus superposed with the beam 8, resulting in a synthesized light beam 10. A four-dividing photodiode 24a as a means for detecting a position of a light point is fixed to a moving body 15 which is movable in a direction of one axis 16. The beam 10 is brought into the photodiode 24a. A straightness of the moving body 15 can be measured without being influenced by fluctuations of an optical beam 2 of a light source 1 when a position of the light beam 10 is measured by the means 24a.

Inventor: MIURA TAKESHI
IPC: E02B15/00
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To easily encircle driftwoods or the like with a collecting rope without requiring skill and to make the collecting rope foldable without requiring much space when stored by a method wherein a plurality of floats are connected with a rope and a chain is suspended underwater almost horizontally with a plurality of hanging chains engaged to the rope. SOLUTION: Floats 2 are connected together with a rope 3 that is equipped at its both ends with engaging rings 4 convenient for being engaged with a working boat. A chain 5 is suspended with hanging ropes 7 at a position 5-15cm below the centerline of the rope 3. Then, driftwoods or the like floating in a dam are encircled with a driftwood collecting rope 1, and the driftwoods or the like are towed by the working boat. As the chain 5 is suspended underwater, the driftwoods can be encircled freely in curves and resistance of lake water working on towing by the working boat can be minimized. The driftwood collecting rope 1 does not require much space when stored on the ground while being free from entanglement of the rope 3 and the chain 5 when put in use.

Title: Automatic answering telephone set
Inventor: SHIMADA NAOKI
IPC: H04M1/65
Filed: 1984-07-24
Abstract: PURPOSE:To prevent interception of recording contents only with two frequency detecting circuits by detecting two kinds of single frequency signals caused by key depression of a pushphone and attaining remote control only when a generated pattern of the signals is coincident with a scheduled pattern. CONSTITUTION:A key depression signal of a pushphone inputted from a trunk line 10 as a remote control signal is detected by band pass filters 2, 3 for 697kHz and 1,209kHz and PLL circuits 4, 5, and when at least one frequency is detected and a signal (c) goes to H, the result is fetched to a microcomputer 16. The microcomputer 16 compares a generated pattern of each frequency with the pattern set by 5-digit bit switches 18, 19 and when they are coincident (e.g., keys are depressed in the order of 1, 1, *, 2, 1) only, the remote control is attained. Then interception is prevented by using two kinds of frequency detection circuits only.

Title: Remote loop control device
Inventor: TOYOSHIMA KEIICHI
IPC: H04B17/40
Filed: 1987-06-18
Abstract: PURPOSE:To execute the setting and releasing of a fold-back with only a receiving station as an object and to efficiently execute the remote loop control by converting fold-back setting information into a mode different from a normal pattern and making the fold-back setting information of a rear step invalid. CONSTITUTION:When a remote loop control forecasting circuit 2 forecasts, based on a pattern detecting result from a remote loop control circuit 1, that the control circuit 1 executes fold-back control, a signal converting circuit 3 stops the repeating of fold-back setting information by the input of a remote loop control forecasting signal S3, and instead, the fold-back setting information from a DET is converted into a mode different from a normal pattern and sent to a signal line 7. The control circuit 1 sends a remote loop control signal S4, switches fold-back switches 4a and 4b, and thus, a fold-back loop is formed between said receiving station and the DET.

Title: Method for rolling strip having longitudinal line
Inventor: UEHORI YUJI
IPC: B21B1/22
Filed: 1986-06-28
Abstract: PURPOSE:To form longitudinal lines having a specific shape with small rolling load by incorporating rolls each provided with a recessed crown, as elements to constitute a rolling roll pair, to plural rolling stands at the time of forming said longitudinal lines continuously. CONSTITUTION:Shape grooves 3 having 2-8mm depth and 2-15mm width are inscribed circumferentially to the prescribed axial positions in the barrel part of the rolling roll 1 at 20-50mm intervals in the axial direction. The recessed crown 11 is provided to the roll 1 in a manner that the diameter at the barrel end increases gradually linearly from the side slightly inner the position where the end of a strip S contacts the roll toward the barrel end of the roll. As a result, the position of the strip S once shifted toward the SW side acts to return to the original normal rolling position. The center of the roll barrel part and the transverse center of the strip S are self-aligned if the rolls 1 provided with the laterally symmetrically recessed crowns are used; therefore, the crushing of the lines formed in the previous pass is obviated.

Patent JP-H04349717-A (JP)
Title: Photoelectric switch
Inventor: TAMINO SHINYA
IPC: H03K17/78
Filed: 1991-05-27
Abstract: PURPOSE:To prevent interference between photoelectric switches even when three photoelectric switches or over are arranged in parallel by controlling a change in a pulse period in response to a light receiving signal level of a light receiving means caused for a period just before a pulse signal is generated from an oscillation circuit. CONSTITUTION:A light receiving signal before waveform forming is outputted from a signal processing circuit 6 to an oscillation period control circuit 9. When a light receiving signal is given from the signal processing circuit 6 to the control circuit 9 just before a pulse signal is outputted from an oscillation circuit 4, the light receiving level is obtained from the light receiving signal and the pulse output of the oscillation circuit 4 is delayed tentatively. Thus, in the photoelectric switches as above, even when, e.g. two sets of photoelectric switches receive a reflected light from the other photoelectric switch just before they emit a light, since the stop time when a light radiates from each photoelectric switch differs, the light projection timing is not coincident and interference is prevented.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To form an image with high image quality by outputting a feature signal from an analytic means, so as to select a first mode in a selecting means concerning a pixel constituting a fine line which is narrower than a prescribed width at halftone. SOLUTION: Data described in page description language(PDL) are transmitted from a host computer 101 to a controller 102, and in the controller 102, the PDL data are interpreted by a CPU 110, expanded into full color images and written in an image memory 109. This full color image is expanded as image data which are separated into four colors corresponding to the output characteristics of an image forming device 103 and a TEXT signal for identifying a character/drawing is generated. When a PDL expanded pixel is a pixel constituting a straight or curved line as wide as the width of one pixel in the halftone, the TEXT signal is set to '1' showing that it is character/drawing. Thus, concerning the pixel constituting the fine line narrower than the prescribed width at halftone, the feature signal is outputted so as to select the first mode.
