Abstract: PURPOSE:To provide a heat sealing film consisting basically of flexible polyester having favorable heat sealing properties also, by a method wherein heat sealing resin is laminated to at least one side of a biaxially oriented polyester film having a specific Young's modulus. CONSTITUTION:In a flexible polyester film constituting a heat sealing polyester film, a Young's modulus is 10-250kg/mm<2>, preferably 50-200kg/mm<2> and in the case where the Young's modulus is too low, it is not preferable since handling properties are not favorable because of lack of firmness when it is made into a bag. Furthermore, it is necessary that the film is biaxially oriented from viewpoints of aging of the Young's modulus, a using temperature range and productivity.

Title: Photomultiplier
Inventor: HIRAGAKI KEIICHI
IPC: H01J31/50
Filed: 1992-01-31
Abstract: PURPOSE:To reduce the image distortion by forming a recessed plane having a curvature determined on the basis of the electron image focus plane of a lens on the fluorescent surface supporting side of a glass substrate, and forming a projection surface having a curvature determined so that a visible light image forms a planary imaginary image, viewed from an output side, on a visible light image output side. CONSTITUTION:Since an image focus plane due to an electronic lens is obtained by the simulation using CAD, the degree of freedom of the curvature of the image focus plane is increased, and the preparation of an output image having little strain is facilitated by a glass substrate having a curved recessed surface. Further, since the radiation plane of the substrate is formed to a proper projection surface through the lens calculation, the visible output light beam can be made parallel. For example, the plane faced to the electron orbit due to the electron lens of a glass substrate 28g is formed to a recessed surface, and a fluorescent body 28f is formed, and the plane for outputting the visible light beam is formed to a projecting plane. Accordingly, the image focus plane can be obtained by the electron lens without using a fiber plane or a special collimating lens, and the light image free from distortion as a whole can be obtained.

Title: Phase synchronizing circuit
Inventor: IHIRA KUNINOSUKE
IPC: H04L27/18
Filed: 1981-03-30
Abstract: PURPOSE:To ensure the stable working of a phase synchronizing circuit, by presetting a counter which devides the output signal of a variable frequency oscillator in case the phase of an input signal is outisde the range of syncronism. CONSTITUTION:When the control signal to be applied to a control terminal CONT is set at 0, AND circuits G1 and G2 are opened only for the period during which the output signal of a terminal Q of a flip-flop FF1 is set at 1. Then the output and input signals of a counter CTR are applied to a phase detector PD to detect the difference of phase. If the input signal has a phase within a period of 1 of the synchronizing range signal, an FF2 is set continuously with the terminal Q set at 1. At the same time, the phase difference is detected by the detector PD and a variable frequency oscillator VFO is controlled to control the frequency of oscillation to ensure the coincidence of phase. In case the input signal has a phase within the period of 0 and outside the synchronizing range, 1 and 0 are applied to a clock terminal C of an FF2 and a data terminal D, respectively. Thus the terminal Q of the FF2 is set at a set signal. This set signal is applied to a preset terminal PS of a counter CRT.
