Title: Optical disk recording/reproducing device with diagnosis function
Inventor: WACHI SHIGEAKI
IPC: G11B7/09
Filed: 1987-03-27
Abstract: PURPOSE:To quickly cope with a trouble generated at the time of recording/ reproducing by providing a servo system circuit on the recording/reproducing side with a transmission element responding to a disk run-out frequency component with high gain and allowing a comparing means or the like to monitor its output signal. CONSTITUTION:It is necessary to regulate a run-out variable (mum) normally controlling an optical disk from a servo system on the device side by a frequency component and to include it within the range of the transmission characteristics of the servo signal similarly to the servo system. When the rotational speed of the optical disk is fixed, the optical disk including its radial run-out variable in an area A and an axial run-out variable in an area B accurately radiates a laser beam spot on a recording track by tracking servo and a focus servo to attain recording/reproducing. The run-out variable of the loaded optical disk is detected by a deciding means to cope with a generated trouble.

Title: Electronic printer
Inventor: TASHIRO TSUNEO
IPC: B41J2/44
Filed: 1978-06-14
Abstract: PURPOSE: To achieve the improvement of picture quality and multifunctioning by reflecting laser light by a rotary mirror composed of polyhedral mirros and scanning the original and photoreceptor alternately every plural times per rotation of the rotary mirror.  
     CONSTITUTION: Oscillated laser light is reflected by the mirror face m 1  of a rotary trihedral mirror 21 and the reflected light moves from a 1  to a 2 , whereby the scanning of the original 30 is finished. The reflected light from the original 30 is photoelectrically converted and is stored in a memory device 26. Further the rotary mirror 21 continues to rotate and during the time when the reflected light from the mirror face m 2  moves from b 1  to b 2 , a photoreceptor 1 is scanned. The signal  having been stored in the memory device is applied to a modulator 16 in synchronization to this scanning and the modulated laser light exposes the photoreceptor 1. Since the original and photoreceptor are scanned every 3 times in one rotation of the rotray mirror in this way, the picture quality improves and the enlargement and scale down of the images are also made possible by the simple constitution, thus multifunctioning may be achieved.

Title: Crystal growing method
Inventor: FUJINO YOSHIO
IPC: C30B19/00
Filed: 1990-03-23
Abstract: PURPOSE:To prevent the formation of layer containing oxygen at the interface between a substrate and a crystal film and to make it possible to obtain the crystal having the excellent electric characteristics in a liquid-phase epitaxial method by performing the contact of a raw material solution to the surface of the substrate by floating a plate for adsorbing oxide on the raw material solution. CONSTITUTION:The case wherein a carbon plate is used as a plate for adsorbing oxide is used as an example. A carbon plate 5 is floated on a dissolved raw material 2. When the raw material is dissolved, the surface is covered with an oxide 6. When a container 3 is inclined so as to bring the dissolved raw material 12 into contact with a substrate 1, the raw material 2 flows to the side of the substrate 1, but the oxide film 6 in contact with the carbon plate 5 does not flow and it is in the intact adsorbed state to the carbon plate 5. The surface of the dissolved raw material 2 becomes the clean surface until the raw material 2 comes into contact with the substrate. Especially, the oxide film on the upper surface is removed at this time. Thus the dissolved raw material 2 comes into contact with the substrate 1. A layer containing oxygen is not formed between the substrate and an epitaxial crystal film, and the crystal film having high purity and excellent electric characteristics is grown.

After the completion of discharge, the substance is extruded from the tip of the nozzle by the air pressure and completely cut off from the nozzle. At that time, the air volume required for the operation is, for instance, approximately 1 cc in the standard state.  The substance of accurate volume can be fed to a section to be fed and the adhesion of the substance to unnecessary sections can be prevented by the arrangement.

The space S1 is formed in a dimension (l2) that a semiconductor substrate 1 doesn't come into contact with the insulating material 108 even through the minimum relative deviation (l1) arised due to the following two: the maximum relative deviation (l1) between the semiconductor substrate 1 and the insulating material 108 due to the dimensional torelance of a positioning jig (not shown in the diagram), which is used when the semiconductor substrate 1 is bonded, parts and so forth; and the thickness (t1) of the semiconductor substrate 1. (Provided that, l2>l1 and t2>t1). Accordingly, there is no possibility that the semiconductor substrate 1 and the insulating material 108 come into contact with each other. As a result, as no contact of both generates even during the time when heat is dropping, no crack and deficit generate in the semiconductor substrate 1.
