Title: Luminous tube for walk control chain and luminous plate for indicating walking place
Inventor: GOTO KAZUAKI
IPC: E01F9/669
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a luminous tube and plate which can enhance the visibility of a walk control chain with light emission even when no external light is available, for example in the nighttime, prevent a pedestrian from being hitched by the chain or from tumbling, and can be mounted on the chain easily.

Title: Recording and reproduction device for video signal
Inventor: TAKEUCHI AKIHIRO
IPC: H04N5/782
Filed: 1991-08-29
Abstract: PURPOSE:To attain reproduction in an accurate time by supplying a vertical synchronizing signal to a drum servo, rotating rotary head synchronously with a field frequency of an input video signal and implementing reproduction at a same field frequency as the recorded field frequency. CONSTITUTION:A video signal from an input terminal 1 is inputted to a synchronizing separator circuit 2, from which a vertical synchronizing signal is detected. The signal is given to a frequency detection circuit 3, from which the frequency of the signal is detected and a field frequency command signal in response to the detected frequency is multiplexed onto a video signal by a memory 4 and a switch 5. The multiplexed signal is modulated by a frequency modulator 6 and the modulated signal is recorded on a tape 8 through a rotary head 7. Furthermore, the vertical synchronizing signal is fed to a drum servo 9 as a reference signal for a rotating phase. Thus, the head 7 is driven synchronously with the field frequency of the input video signal. Thus, the signal is reproduced by the same field frequency as that of the recorded signal.

Title: Image formation device
Inventor: TANIGUCHI MAKOTO
IPC: G03C5/56
Filed: 1990-08-20
Abstract: PURPOSE:To ensure that ink is transferred smoothly from a development roller to an image formation element and defective printing due to irregular ink deposition or ink run on a recording medium is prevented by specifying the unevenness of a coated surface of an optically reversible isomerized material. CONSTITUTION:An optically reversible isomerized layer 102 indicates such a phenomenon that the structure of a cis element is isomerized by a trans element due to light/exposure 105. Therefore, a latent image is formed on an image formation element 103 by selective light exposure. To allow migration of ink from the surface of an inked latent image formation element to a medium for image transfer 111, both have to be allowed to come in contact with each other and then have to be peeled off the other. However, if the surface unevenness is tolerated to 0.01mum or lower, their mutual adhesive power increases resulting in an unstabe peeloff position fixing. Subsequently, image quality deteriorates significantly due to delicate differences in transfer parameters such as temperature, humidity and the rotary speed of an image formation element. On the other hand, if the accuracy of unevenness on the coated surface of the optically reversible isomerized material is adjusted to a tolerance of 0.01mum or higher to 1mm or lower, stable transfer and peeloff processes are ensured, resulting in the mentioned transfer parameters causing no change leading to any problems. Thus a satisfactory print image is obtained on the medium for transfer 111.
