IPC: G02F1/13
Filed: 1989-06-27
Abstract: PURPOSE:To surely erase information displayed on a liquid crystal display layer by supplying power to a resistance layer laminated on the liquid crystal display layer to generate heat and heating this liquid crystal display layer with respect to a medium where the phase change due to heating/cooling of a high polymer liquid crystal material is used to display information. CONSTITUTION:The medium is provided with a liquid crystal display layer 5 essentially consisting of the high polymer liquid crystal material whose phase is reversibly changed by heating/cooling, a resistance layer 4 laminated on the liquid crystal display layer 5, and a pair of power supply electrodes 7 and 8 electrically connected to the resistance layer 4. When a current is given to the resistance layer 4 through power supply electrodes 7 and 8, this layer 4 generates heat to heat the whole of the liquid crystal display layer 5. When the current supply to the resistance layer 4 is stopped after the temperature of the liquid crystal display layer 5 is raised to the isotropic phase transition temperature or higher by this heating, the temperature of the liquid crystal display layer 5 gradually falls together with that of the resistance layer 4. Thus, a gradual cooling condition is satisfied, and the whole of the liquid crystal display layer gets cloudy to surely erase the display.

Title: Signal processing circuit
Inventor: KOKUBU NOZOMI
IPC: H04B1/3822
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To always keep a good receiving state by placing a higher harmonic component reduction circuit in a signal processing circuit for suppressing the harmonic noises. SOLUTION: The harmonic component level is limited by a higher harmonic component reduction circuit 3 for the clock signal that has undergone its waveform shaping via a waveform shaper 2. Based on this clock signal, a CPU core part 4 performs the signal processing, according to the contents of a program ROM 5. The cut-off frequency of the circuit 3 is set at a level sufficiently higher than the frequency of the clock signal, to secure an operating margin and also set at a level sufficiently lower than the receiving frequency band of an equipment, including a receiving device for securing the attenuation of a higher harmonic component. Thus, it is possible to obtain a signal processing circuit which suppresses the undesired radiation and does not deteriorate the receiving performance by limiting the higher harmonic component level of the clock signal via the circuit 3.

IPC: G01V9/00
Filed: 1980-11-25
Abstract: PURPOSE:To detect an end part of a roll of recording paper without impairing operability of both exchange and replenishment of the roll of papr by providing a shaft which pushes up the outermost layer of the roll of paper at all times, and providing a detection lever to the position corresponding to a groove on said shaft. CONSTITUTION:To fit a roll of recording paper 1 to a frame 25, first, a handle 29 is pulled, then the frame 25 is turned in the arrow direction 67 centering around supporting shafts 31, 32. Flanges 21 and 22 are fitted into the roll 1 and its supporting shafts are inserted into a notch 43 of brackets 35 and 36. After an unraveled lead-out part of the recording paper is transferred to a lead-on roller, the frame 25 is replaced at a closing position by pushing up the handle 28, then a shaft 52 rotates in the reverse direction of that shown with the arrow 69 and revolves almost one round through passing under the outermost layer of the paper 1. The shaft 52 is in a condition in which said shaft pushes up the outermost layer of the paper 1 at a place part from a lead-out point 71 of the paper 1 by a constant distance. As the paper 1 is consumed and its end passes the shaft 52, a ditection lever 53 falls into a groove 52a and is detected with a detection switch 57 through a turning of an actuating lever 55.

Title: Facsimile equipment
Inventor: YORITA TERUYUKI
IPC: H04M1/64
Filed: 1992-06-23
Abstract: PURPOSE:To ensure remote control by invalidating a function that selects a telephone line for a facsimile equipment through the detection of a non-voice state of the line upon the receipt of a password signal used for controlling remotely an automatic answering telephone set. CONSTITUTION:A password commanding remote control from a telephone set at a visiting location is sent to a telephone line L as a DTMF signal. A controller 1 detecting a signal with a DTMF signal detection circuit 11 discriminates whether or not a password of the signal is coincident with a number of a password memory 6 and the detection by a non-voice state detection circuit 14 is stopped when coincident. Thus, even when the non-voice state is consecutive while remote control to listen to a recorded message is implemented and a tape is rewound, the controller 1 does not detect the non-voice state. Thus, since a line L is not switched to the position of a MODEM circuit 8 but kept to the position of an automatic answering telephone set 10, the remote control is ensured.
