Title: Optical disk device
Inventor: ISHIBASHI KENZO
IPC: G11B7/00
Filed: 1988-03-31
Abstract: PURPOSE:To easily generate correct recording pulse width by providing a device to sample recording data by recording clock, and a delay element capable of being constituted only inside an LSI circuit. CONSTITUTION:Recording data WTDT is made previously to change at the time of the fall of the recording clock WTCK, and a controller outputs respective data at this timing. Then, an FFDFF1 samples the recording data WTDT at the rise of the recording clock WTCK. Thus, distortion which occurred on a transmission line from the controller to an optical disk device 1 can be canceled. Now, when a selector SEL selects delayed data DWTDT, since a selector output DWTDTS comes to delay sample data SWTDT1 by one clock portion calculated in terms of the recording clock WTCK, the width of a recording pulse PPMDT can be made to be the half of a transfer period. Thus, the optical disk device capable of generating the modulated signal of the correct pulse width not influenced by the distortion on the transmission line is obtained.

Title: Current lead using oxide superconductor
Inventor: TAKITA KIYOSHI
IPC: H01B12/02
Filed: 1993-04-08
Abstract: PURPOSE:To obtain a current lead which can avoid the burnout of a low temperature side lead due to quench of oxide superconductor and continue to supply a current to a superconducting coil, whose lead has little permeated heat, and simple constitution. CONSTITUTION:A current lead 13 electrically connects a superconducting coil 1 accommodated in a vacuum heat insulation vessel 2 and kept at a very low temperature, with an external power supply. A high temperature side lead 4 is connected in series with a low temperature side lead 5, in the current lead 13. Stainless material as the low thermal conductivity metal is used for a hollow pipe surrounding oxide superconductor 9 of the low temperature side lead, and turned into bypass conductor 17 connected in parallel with oxide superconductor. Since the thermal conductivity is low, permeating heat is usually reduced. When quench is generated in the oxide superconductor 9, the current in the oxide superconductor flows through the bypass conductor 17, and the heat generation of the oxide superconductor 9 is restrained, so that burnout is prevented.

Title: Automatic focusing optical pickup
Inventor: MORI SADAO
IPC: G02F1/35
Filed: 1989-04-03
Abstract: PURPOSE:To omit the drive of an actuator and to easily miniaturize an automatic focusing optical pickup by reflecting and amplifying the reflected light via a phase conjugate mirror and reading the information out of a disk. CONSTITUTION:A laser resonator consists of a condensing means 21 where the focal distance varies continuously between the center and peripheral parts and a phase conjugation mirror 8. In other words, at least a part of the light irradiating a disk 2 forms a focal point on the surface of the disk 22 and is reflected there despite the fluctuation caused to the distance between an optical pickup and the disk 22 as long as the disk 22 is irradiated by the means 21 having different focal distances. This reflected light is partly reflected and amplified by a phase conjugate mirror 8 and therefore can be condensed again on the surface of the disk 22 via the means 21. As a result, the laser is oscillated between the surface of the disk 22 and the mirror 8 and the information written on the disk 22 is read out by means of a part of the oscillated light. Thus it is not required to drive an objective lens by an actuator and therefore the optical pickup is easily miniaturized.

Filed: 1992-03-04
Abstract: PURPOSE:To improve a convenience by setting an extension designation number capable of calling plural extension telephone sets, and simultaneously calling the plural extension telephone sets when the extension designation number received at the time of a trunk line incoming call is equal to the pertinent extension designation number. CONSTITUTION:A difference telephone number is applied to each master set 1 and a slave set 30, and the number of the end digits 1-4 of the number is stored in the CPU 5 of the master set 1 as the extension designation number. Then, the individual calling of the extension telephone set designated by the extension designation number from a subscriber's switchboard at the time of the trunk line incoming call is operated. That is, when the extension designation number is '1', the trunk line incoming tone of a slave set 30 is rung, and when the extension designation number is '2', the trunk line incoming tone of a master set 1 is rung. Then, when the extension designation number is '3', both the master set 1 and the slave device 30 are called, and the trunk line incoming tone of the master device 1 is rung, the trunk line incoming tone data are transmitted to the slave set 30, and the trunk line incoming tone of the slave set 30 is rung. Therefore, even when the other party is present at any place, a speedy response can be attained.

Title: Etching method
Inventor: YASUI JIYUUROU
IPC: H01L21/306
Filed: 1979-06-28
Abstract: PURPOSE:To prevent the damage to a semiconductor substrate holder due to overetching during the etching removal of an insulator film attached in the vapor phase growth by coating it with an etching resistant thin film beforehand. CONSTITUTION:The semiconductor substrate holder 5 alone is inserted into a reaction tube heated by means of the LPCVD device (pressure reduction chemical phase accumulation) and coated on the surface with a polycrystaline Si film about 0.5mum thick under the reduced pressure by thermal cracking of SiH4 gas. As one coating is not enough because the contact portion with the inner wall of the tube may not be yet covered sufficiently or may be insufficient in thickness even if it covered entirely. Another polycrystaline Si film is formed on the holder 5 under the same conditions by turning it upside down. The holder thus treated is used to form the Si3N4 on the semiconductor substrate by the normal LPCVD method. This can protect the holder from any etching even if the Si3N4 film is removed emmersed in the HF liquid after used several time.
