Title: Recording method for optical disk
Inventor: GOTO YASUYUKI
IPC: G11B7/0045
Filed: 1986-09-25
Abstract: PURPOSE:To attain high density recording by projecting a laser beam for information recording with a shorten interval than the diameter of the laser beam and forming a bit of information recorded in a recording layer to be smaller than the diameter of the laser beam. CONSTITUTION:The recording bit with the laser beam consists of a central high reflectance part 1 and a low reflectance part 3. For example, it the laser light beam whose diameter is 1mum is superposed and written in an arrow direction with dislocating by 0.5mum, the recording bit consisting of the high reflectance part 1 and the low reflection factor part 3 occurs with superposing one another but the reflectance part 1 where the low reflectance part 3 of a adjacent bit is superposed changes and turns into the low reflectance part 3 and the reflectance and the crystal state of the low reflectance part 3 becomes equal to those of a non-cast part. Therefore only crescent-shaped high reflection factor parts 1 appear on the recording layer and only bit 5 in the end becomes a circle. Since the recording is executed by using smaller bit string than the diameter of the laser beam, the density of recording is increased.

Title: Conveying method in use of gravity
Inventor: KITAOKA SATOSHI
IPC: B65G47/88
Filed: 1982-12-27
Abstract: PURPOSE:To prevent an article from being damaged as well as to make a lot of articles alingable in line automatically, by absorbing the inertia force in a way of letting a conveying load collide with a rotatable stopper, while rotating the stopper and thereby making the conveying load travelable, in time of conveying the load on a sloping conveyance passage by means of gravity. CONSTITUTION:A conveyed load 2 rolls on a sloping conveyance passage 1 and collides with a stopper 3. Since the stopper 3 is provided with a shock absorber 4, the conveyed load 2 is absorbed of its inertial force when colliding with the stopper 3. Therefore, the stopper 3 rotates clockwise by dint of gravity on the conveying load, retreating from the surface of the conveyance passage 1 and the conveyed load 2 rolls on the sloping conveyance passage 1 by dint of the gravity. With this constitution, any damage due to collision in time of stoppage of the conveyed load is prevented and, what is more, a lot of conveyed loads can be aligned in line.

Filed: 1986-09-26
Abstract: PURPOSE:To contrive to expand the upper/lower limit of an input signal level by controlling the conducting state of a switching means provided between a base and an emitter of a 1st stage transistor (TR) of TRs of Darlington connection based on the input signal level. CONSTITUTION:When both the voltage of input signals V1, V2 are smaller than a reference voltage Vref, the output voltage of the 1st and 2nd differential amplifiers D1, D2 goes both to 'H' level, then an output voltage of a NOR gate E goes to an  L' level. As a result, a TR Q14 is turned off and a current 12 is supplied respectively to emitter electrodes of TRs Q3, Q4 by a constant current source B and a current mirror circuit comprising TRs Q10, Q12. Then the circuit acts like a converter provided with a differential TR pair of Darlington connection. On the other hand, when the input signals V1, V2 are both larger than the voltage of the reference voltage signal Vref, the circuit acts like a comparator provided with a single differential TR pair.

Title: Method and device for x-ray photoelectron spectroscopic analysis
Inventor: NAKAOKA SHIYOUICHI
IPC: G01N23/227
Filed: 1983-11-30
Abstract: PURPOSE:To enable local analysis of a sample surface by X-ray excitation of a non-conductive sample by providing a fine linear hole (slit) to a mask disposed between the sample and an X-ray source and irradiating the X-rays through the slit to the sample. CONSTITUTION:A mask is placed between a sample 4 and an X-ray source 2 and a fine linear slit 3 is provided to the mask. X-rays are irradiated to the sample 4 through the slit 3 and the slit 3 is parallel moved, by which the one-dimensional data of the sample 4 is obtd. The slit 3 or the sample 4 is then rotated and the slit is moved parallel in the same way as mentioned above; thereafter, the parallel movement and the rotation are alternately performed and the resultant data is arithmetically processed by using a back projection method to be used for an X-ray tomographic device, by which the two-dimensional data on the sample surface is obtd. The detection of the small signal which is buried in the signal from the mask material and is not detectable in the prior art is thus made possible and the resolving power is improved by decreasing the slit width.
