Title: Detection system for state change
Inventor: NAKAYAMA HIDEO
IPC: G06F17/40
Filed: 1989-07-14
Abstract: PURPOSE:To accurately detect a state change with simple constitution by judging that there is the state change only when state value data agrees with comparison pattern data and state value data does not agree with state value data in a former period. CONSTITUTION:A state value data storage means 20, a comparison pattern data storage means 21 and a comparison judgement means are given. The comparison judgement means 22 compares state value data for the number of the bits of comparison pattern data, which continues to the bit to which the newest state value is inputted among state value data with comparison pattern data. Only when state value data agrees with comparison pattern data and it does not agree with state value data in the former period, from the comparison judged to be that there is the state change and judges it to be without state change except for this case. Thus, the state change can accurately be detected with simple constitution.

Abstract: PROBLEM TO BE SOLVED: To prevent the opening position errors of holes caused by the elongation/ contraction of materials in laser processing without requiring any image film by sequentially forming conductive layers and resist layers on both surfaces of an electric insulating plate and forming the holes with a laser processing, and then, removing the resist layers after circuits are formed by removing conductive parts in unnecessary sections. SOLUTION: After conductive layers 2 and resist layers are sequentially formed on both surfaces of an electric insulating plate 1, holes are formed to one of the conductive layers 2 through the insulating plate 1 with a laser beam in accordance with the design patterns of circuits. At this point, the laser beam projecting positions are corrected in conformity wit the expansion/contraction of the plate 1 and layer 2. After the parts of the layers 2 which are not protected with the resist layers are removed and circuits are formed on both surfaces of the plate 1, the resist layers are removed.  In addition, groove holes 5 are formed to the conductive layer 2 on the opposite side through the parts of the insulating plate 1 corresponding to circuit connecting spots on both surfaces of the plate 1 with the laser processing and the surfaces of the layers 2 and holes 5 are plated with a conductive metal 6, and then the circuits formed on both surfaces of the plate 1 are electrically connected to each other.

Title: Bending of optical fiber
Inventor: UEDA RISA
IPC: C03B23/06
Filed: 1992-06-16
Abstract: PURPOSE:To prevent damage by inserting an optical fiber into a metal protecting tube, locally heating the part to be bent according to the high-frequency heating method and bending it into a desired shape. CONSTITUTION:A protecting tube 2 made of a metal such as stainless steel and containing an optical fiber 1 inserted thereinto is fixed to a fixture unit 3 and a copper plate 4 having a hole through which the metal protecting tube 2 passes is set so as to fit to the part to be bent. The copper plate 4 is then charged with electricity from a high-frequency power source so as to quickly and locally heat a part of the metal protecting tube 2 existing inside the copper plate 4 according to the high-frequency heating method. Thereby, the optical fiber 1, together with the metal protecting tube 2, is softened by conduction of the heat so as to be readily deformable. After slowly bent in the right or left direction along the arrow marks up to a desired bending angle and radius at a sufficiently softened state, heating is stopped and the optical fiber is allowed to stand so as to be cooled and solidified. Thereby, the objective optical fiber 1 free from damage can be obtained. In addition, damage of the metal protecting tube 2 due to melting is not observed.

Abstract: PURPOSE:To detect the tape residual quantity without changing the position of a tape by starting the 1st tape running mode for detecting the quantity of tape, stopping the tape running mode after the end of tape quantity detection and reversing the tape by the tape running length. CONSTITUTION:A pulse generated from supply and winding reel drive detectors 1, 7 is inputted to a tape residual quantity detector 25 at the tape running mode to detect the tape residual quantity. In this case, a pulse generated from a photo sensor 5 is inputted to a counter circuit 26 and pulse number is counted up. When a time predetermined to be longer than the time required for detecting tape residual amount elapses, an input is given from a system control circuit 28 from a system control circuit 28 so that the reversing mode is obtained by the circuit 28. A counter circuit 26 is switched to down-count at the same time and when the result of calculation reaches 0, the tape running is stopped. Thus, the tape is reversed by the tape length run for the detection of tape residual amount and the tape restores to the original position.

This latent image is developed by the 1st developer 4 and with a toner having a comparatively high degree of toner charging. Thus, a high charging toner image is formed. This developement is caried out in such a way that the electric charge of the electrostatic latent image is not completely neutralized. After the development, the developer 4 is set contactless to the photoreceptor 1. After this, a comparatively low charging toner image is formed on the above-mentioned toner image by the 2nd developer 5. Then only the low charging toner image is transcribed onto the copy paper 8 at the position of a transfer roller 6. The developer 5 is used again to repeat the transcription. Thus plural sheets of copy are obtained.

Subsequently, the battery 14 is taken out of the water 12 and a minute conductivity measuring electrode 15 is immersed in the eluted water 12' to measure the conductivity thereof by a conductivity meter 16. On the other hand, the conductivity of only the water 12 for inspection is measured and both values are compared. By this method, the quality of the battery to be inspected due to the degree of the leaked liquid can be discriminated.

Abstract: PURPOSE:To compare an original image and the processed image (or mode distribution) simultaneously by one monitor by displaying the original image and the processed image (or mode display) on an optional part. CONSTITUTION:An input signal 50 thinned out at the sender side is inputted to an interpolation circuit 1. The interpolation circuit 1 outputs interpolation images 52-55 corresponding to the four kinds of thinning-out modes to a selector 2. A mode signal 51 from the sender side is outputted to the selector 2 via a selector 5 and an interpolation image in response to the mode is outputted as the output signal 56. A vertical synchronizing signal V clears a counter 4 to set a FF 61. The counter 4 counts a horizontal synchronizing signal H and generates a clear signal 60 when a value m1 inputted from a switch SW1 is reached to reset the FF 61. The selector 5 selects the mode signal 51 when the FF 61 is set as the output signal 57. When the FF 61 is reset, the value m2 inputted from the switch SW2 is used as the output signal 57 to select a non-interpolation signal (original picture) 52 by the selector 2.
