Inventor: KIRINO FUMIYOSHI
IPC: G11B11/105
Filed: 1987-02-12
Abstract: PURPOSE:To suppress degradation in disk characteristic caused by the corrosion of a recording film occurring in a resin substrate or resin layer and to prolong the life of the disk by providing a transparent inorg. material layer to the boundary between the resin substrate or the resin layer and information recording medium. CONSTITUTION:The resin surface of the reversible optical disk formed by using the plastic substrate 1 or the substrate 1 having the resin layer is coated with the thin transparent inorg. compd. film 2 to form said disk. Since the material bleeding from the resin or the material diffusing in the resin can be thereby shut off, the deterioration in the properties of the recording film 4 by such material is suppressed and the life of the disk is prolonged. The thin film 2 increases the adhesive strength of an optical effect film 3 and the substrate 1 by relieving the stress therebetween. The influence on the optical path is decreased to a negligible level and the film is formable to a desired thickness if a material having the same refractive index as the refractive index of the substrate 1 material is used particularly for the transparent inorg. compd. film.

IPC: G03B15/00
Filed: 1984-02-17
Abstract: PURPOSE:To obtain a television video with less distortion by arranging an image pickup device having plural optical lenses and plural image pickup elements so that their optical fields will be adjacent to each other in their borders, scanning sequentially the image pickup elements in accordance with the location, switching and synthesizing video signal outputs and outputting one video signal with a wide range of a field. CONSTITUTION:A group of an La and an Ra consist of an optical lens 1a and image pickup elements 2a, that of an Lb and an Rb consist of an optical lens 1b and an image pickup element 2b. The former group and the latter group show right and left visual field ranges of an image pickup mechanism consisting of these groups, and an A and a B denote angles formed by said groups. At this time, when the Ra and the Lb are arranged so that they will be parallel, a visual field C in combination of two image pickup mechanisms turns out a sum of the visual fields A and B of their mechanisms. As a result, the image pickup element 2b is scanned in the direction from the La to the Ra, at the moment the scanning reaches the Ra, the image pickup element 2b is scanned in the direction from the Lb to the Rb, and simultaneously the image pickup element 2b and its video signal output are switched in synchronization with the scanning; therefore approximately the similar output of a video signal output obtained by continuous scanning of the visual field C from the La to the Rb can be obtained.

Title: Radiation monitor
Inventor: MATSUO MASAKAZU
IPC: G01T1/17
Filed: 1980-03-05
Abstract: PURPOSE:To make possible an accurate measurement of radiation without depending upon the magnitude of a counter ratio by setting a pulse amplifier which can control a gain by a current flows through a Geiger-Muller (GM) counter. CONSTITUTION:When a radiation is incident on a GM counter 1 to form a current path in the GM counter 1, a current flows in a route of the second resistor 2, the GM counter 1, and the third resistor 11 as a GM current detection circuit which detects the GM current flows in the GM counter 1. As the result, a voltage proportional to the GM current is appeared at both ends of the resistor 11. When the radiation incident on the GM counter 1 increases, the GM current also increases, thereby increasing the voltages of both ends of the third resistor 11. In this case, the decrease of the value of a wave crest of the pulse signal appears at the negative side of a capacitor 5 is corrected by increasing the gain of a pulse amplifier 6 detecting the increase of the GM current. Thus, the value of an output wave crest of a gain automatic controlling pulse amplifier block 13 becomes always constant and the accurate measurement is possible.

Title: Slide type hanging tower
Inventor: ABE TETSUO
IPC: E02D7/16
Filed: 1981-03-03
Abstract: PURPOSE:To quickly drive a pile in the construction of a marine structure by arbitrarily adjusting the driving angle of a hammer by sliding the position of a hanging leader attached to a pile-driving tower. CONSTITUTION:A hanging leader 1 is supported and hung on a pile-driving tower(ship) 5 by means of a catch fork 4 with a slide type guide. Then, the inclined angle and height of the hanging leader 1 are so set that the erected pile 18 can be driven by a hammer 2. At a time when the hammer 2 is dropped from the point A to the point B, the catch fork 4 is removed from a can 3, the leader 1 is brought down to a desired level, and then the cap 3 is again fixed to the catch fork 4 and the driving condition of the hammer 2 is set. Also, the pile- driving ship 5 is made to approach by as much as the height difference for adjustment. By this, an inclined angle from vertical driving to slant driving can be arbitrarily obtained and also the hanging leader 1 can be made shorter. Thus, the weight of the device can be reduced and the installation cost can also be cut down.
