Filed: 1989-08-10
Abstract: PURPOSE:To possess both reproducing and additional recording functions by equipping a disk substrate for reproducing only having a recording layer for reproducing only and a disk substrate for additional recording only having a recording layer for additional recording only. CONSTITUTION:The disk substrate 1 for reproducing only and the disk substrate 2 for additional recording only are set opposite to each other, and spacers 5 are provided between them, where an air layer 6 is formed to be an air gap by the spacers 5. This air layer 6 exhibits a ventilation effect to allow good writing when the disk substrate 2 for additional recording only is a pitot forming type.

Abstract: PURPOSE:To make it possible to examine an object being examined having an arbitrary size in desired resolving capacity and image quality, by raising and falling a radiation generator and a detector group in a synchronous relation to each other while rotating the object being examined. CONSTITUTION:An object 11 being examined is secured to a work moving truck so as to be made rotatable by a rotary drive source 18 while a radiation generator 22 and a radiation detector group 23 are suspended from the suspension member provided to a support so as to hold the object being examined therebetween in opposed relation to each other and made liftable by lift apparatuses 24, 25. A drive control part 35 supplies a rotary drive signal and a lift drive signal to the drive source 28 and the apparatuses 24, 25 by CPU 36 for performing control and signaling according to a predetermined program and the signal from an operation disk. A data collection part 37 receives the signals of the control part 35 and CPU 36 to collect the radiation permeation data of the detector group 23 and reconstitutes an image to display the same to a display apparatus 40. As a result, the troubles of the generator 22 and the detector group 23 can be reduced as well as the object 11 being examined can be attached even if it is large and heavy and the object 11 with an arbitrary size can be examined in desired resolving capacity and image quality.

Title: Recording head of ink jet recorder
Inventor: ARAI TOSHIHIRO
IPC: B41J2/015
Filed: 1986-09-05
Abstract: PURPOSE:To make the flying path of atomized ink stable and prevent mist or dust from settling on a deflecting electrode by providing a holder in which a groove opposed to the side of the deflecting electrode is extended to a position exposed to a gutter, and a cover which is arranged across the groove and has a hole formed on a position opposed to the gutter. CONSTITUTION:If vacuum suction is performed by a gutter 4, air is introduced into a space surrounded by a holder 7 and covers 10, 15 through holes 11, 14. A nozzle 1 is actuated, thereby rotating a drum 6 to print an image. The mist which is generated by atomized ink particles 2 colliding with the gutter 4 without being charged by the deflecting electrode 3, is sucked by the gutter 4 with an air flow, so that the mist is not scattered outside the space. Further the mist generated by the ink particles 2 which run into printing paper 5 via the hole charged by the deflecting electrode 3, does not settle on the surface of the holder 7 or covers 11, 13 and foul the deflecting electrode 3. In addition, an air blown by the rotation of the drum 6 does not hit the ink particles 2 in the holder 7, thus stabilizing the flying path of the ink particles 2.

Title: Semiconductor laser device
Inventor: OKAI MAKOTO
IPC: H01S5/00
Filed: 1987-08-24
Abstract: PURPOSE:To obtain a stable transversal single mode selectivity irrespective of an injection current level, by arranging a phase shift at a specific position from the single end surface of a resonator. CONSTITUTION:Figure shows, by examining the oscillation condition of laser, the normalized threshold value gain difference of the longitudinal mode primarily easy to oscillate, and the longitudinal mode secondarily easy to oscillate, in which phase shift position and phase shift quantity are applied to parameters. The normalized threshold gain difference is one in which the gain difference between the main mode and the sub-mode are normalized, and a stable longitudinal single mode can be obtained in the case where the gain difference is 0.3 or more. The region where a longitudinal single mode is obtained is divided into the following two cases; the case where the phase shift position is part nearer to the center than 0.3l, and the case where it is near to the end surface. Therefore a distributed feedback semiconductor laser having stable selectivity of longitudinal single mode can be obtained irrespective of the injection level, by arranging the phase shift of 0.4pi-0.8pi or 1.2pi-1.6pi in period at a position nearer to an end surface than the interior division point of 7:3 in the length direction of a resonator.

Abstract: PURPOSE:To raise the probability for obtaining a screen being free from an error by constituting the equipment so that as for a program to be sent out repeatedly, even if there is an error at the time of reception, re-reception can be executed automatically. CONSTITUTION:Whether an error exists on a screen decoded in a received picture processing circuit 28 or not is checked by checking the number of picture elements in one line, and a flag of a result of decision is inputted to a control part 32. In the control part 32, in the case a flag for showing that an error exists is set, a value of a time zone in information of a channel, a time zone and a program number preset to a program stored in a storage part 33 is changed to a value of the next sending-out time extracted by an extracting circuit 30 and stored, and the waiting receiving operation is continued again. By this operation, a receiver repeats the receiving operation again when the next sending-out times comes. In such a way, as long as the program is repeated, the probability for obtaining a screen being free from an error is raised.
