IPC: G03G15/01
Filed: 1983-04-05
Abstract: PURPOSE:To improve a color developing property up to an extent that O.H.P. can be used, by applying a liquid state high mol.wt. synthetic resin to a toner particle group whose surface is uneven, on a base body of a transparent high polymer synthetic resin material. CONSTITUTION:A liquid transparent high mol.wt. synthetic resin particle which is atomized by a spray 36 is applied until a toner layer is hidden, to the toner layer side of a color transparent copy which is undeveloped even if it is projected by OHP discharged from a color copying machine, it is dried, and a transparent film layer is provided on the toner layer. The atomized liquid particle discharged from the spray 36 is larger than a particle diameter of a toner, but a diameter of a natural transparent high mol.wt. synthetic resin is smaller than a particle diameter of the toner, and a liquid particle is constituted of the transparent high mol.wt. synthetic resin and an organic solvent having an affinity in a toner itself, therefore, it adheres without a gap to the circumference of a toner layer 41. Subsequently, when its liquid layer is dried, only the organic solvent is evaporated, and a transparent high mol.wt. synthetic resin layer, namely, a coat film 45 only is left in the circumference of the toner layer 41.

IPC: H04M11/00
Filed: 1991-03-25
Abstract: PURPOSE:To allow the terminal equipment to withstand line noise and to prevent occurrence of a communication error by controlling a line termination DC resistance to be a low resistance close to a specified value when its own terminal equipment is a reply terminal equipment with respect to a prescribed no ringing call signal. CONSTITUTION:When a polarity notice section 1 detects a polarity inversion, each terminal equipment changes line termination from values Z1, R1 controlled by an impedance matching section 5 and a DC resistance matching section 6 into impedance matching values Z2, R2. Succeedingly, a no ringing call signal NRS is detected by an NRS detection section 2, and in the case of the NRS for its own terminal equipment, an impedance matching section 9 as a reply terminal equipment controls the line termination impedance to an impedance Z3 and a DC resistance matching section 12 controls the line termination DC resistance to a resistance R3. Then an ANS transmission section 3 sends a reply signal ANS. When plural line terminal equipments are connected, the reply terminal equipment is brought into a low resistance close to the line termination DC resistance by a DC resistance matching section 12 to withstand noise error in an excellent way.

Title: Apparatus for measuring position in pit for tunnel construction method
Inventor: WATARI YOSHIHARU
IPC: G01C15/00
Filed: 1985-03-27
Abstract: PURPOSE:To make it possible to measure the position of a small caliber level where a worker can not operate, by mounting a laser beam emitting means and a light receiving means 9, which converts the light receiving position on a light receiving surface to an electrical positional signal upon the reception of light, both of which moves so as to hold a definite distance therebetween within a mutually viewable range. CONSTITUTION:Even if a level is curved, a laser beam emitting means 6 and a light receiving means 9 are moved while guided through a level 1 by a guide 5 so as to hold a definite distance therebetween within a mutually viewable range and the light receiving means 9 detects the position of laser beam received on the light receiving surface thereof as an electrical positional signal at every moving position to enable the measurement of each position without trouble. Because the positional signal is inputted to a signal processing part 18 along with the distance signal measuring the distance from a measuring reference point to the light receiving means 9, the measurement of the distance from the measuring reference point 12 to the position of the light receiving means can be successively performed by processing both signals.
