Title: Manufacture of compound semiconductor crystal
Inventor: KIYOMURA AKIO
IPC: C30B29/44
Filed: 1980-07-24
Abstract: PURPOSE: To obtain a single crystal or a crystal close to the single crystal by making the contact area of both components having different vapor pressures or the diffusion area of the compound of both components smaller than the area of the compound semiconductor contacting with the melt in an SSD method.  
     CONSTITUTION: When Ga and red phosphorus are used as components having relatively low and high vapor pressures, respectively, a seed crystal 2 is set on the bottom of a crlindrical crucible 1, Ga melt 3 is poured on the crystal 2, and crucible 1 is placed at the upper part of a container 4. P5 is set on the bottom of the container 4. After evacuating and tightly sealing the container 4, P vapor is generated with a heater 6, and the melt 3 is heated to a high temp. with a heater 7. At this time, a doughnut-shaped floating diffusion controller 10 made of graphite is set on the surface of the melt 3, and a GaP film 8 is grown. As a result, the amount of GaP diffusing toward the seed crystal 2 or a growing crystal 9 is reduced, and the concn. of GaP is suddenly reduced at a part just below the controller 10 and is gently lowered toward the crystal growing face. In the whole diffusion range GaP is restricted at the saturation concn. or below.

Title: Optical system moving device
Inventor: TAKAHASHI NAOMASA
IPC: G11B7/085
Filed: 1989-04-21
Abstract: PURPOSE:To attain coarse access, fine access, and tracking by the same driving means, to prevent an objective lens from vibration right after the coarse access, and to attain fast access by providing a specific support means, and allowing an optical head to move finely and smoothly. CONSTITUTION:This optical system moving device is equipped with a bearing member 9 provided to an optical system and a guide shaft 8 where the bearing member 9 is fitted. An air flow is produced in the clearance between the bearing member 9 and guide shaft 8 as the guide shaft 8 rotates to smooth the motion of the optical system such as the optical head 1 because a noncontact state is entered by the dynamic pressure of the air flow. Consequently, the coarse access, fine access, and tracking are attained by the same driving means and the constitution of the access system is simplified. Further, the objective lens is prevented from vibration right after the coarse access, and the fast access is attained.

Title: Frequency measuring device
Inventor: HIGO KIYOUICHI
IPC: G01R23/12
Filed: 1979-08-13
Abstract: PURPOSE: To measure the frequency bands over a wide range in a high accuracy and at the same time realize a compact and light-weight structure for the measuring device, by using two or more sets of phase displacing means and phase discriminating means having different delay times plus the deciding means which compares the outputs of these means in place of the band pass filters.  
     CONSTITUTION: The measuring device consists of delay lines 12a and 12b functioning as the phase displacing means which gives the phase loss or gain proportional to the frequency, phase discriminators 13a and 13b, and frequency deciding circuit 14 which compares the outputs of the above phase discriminators and then decides the original frequency. The input signal of frequency (f) receives T a  and T b  of different delay times through delay lines 12a and 12b each. The outputs of descriminators 13a and 13b show the same value with every application of the input phase difference of 2π, and thus become the voltage proportional to 2πΔfT a  and 2πΔfT b  each. And these outputs are compared with each other at circuit 14 to deliver the original frequency. In this way, a high-accruacy measurement is possible for the frequency bands over a wide range, at the same time realizing a compact and light-weight structure of the measuring device.
