Title: Magnetic disk controller
Inventor: TOMITA HIROSHI
IPC: G06F3/06
Filed: 1986-10-24
Abstract: PURPOSE:To prevent a time from being spent wastefully without necessitating the rewrite of data written normally, by storing the information of a write instruction that the data is written at present when power failure is generated, and sending the information to a central processor by taking out stored information of the write instruction after a power source is applied again. CONSTITUTION:A magnetic disk processing circuit 120, in case the abnormality of the power source is detected while the write operation of the data on a magnetic disk device is performed, drives a data transfer circuit 110 through a line 203 before the hit or the failure of the power source is generated, and interrupts the write operation of the data, and also, stores the information of the write instruction received from the central processing unit through a line 202, in a non-volatile memory cell 130 through a line 204. The magnetic disk processing circuit 120, after applying the power source again, sends the information of the write instruction fetched through the line 204 from the non- volatile memory cell 130 to the central processing unit through the line 202.

Title: Semiconductor device transfer equipment
Inventor: TANAKA TAKAO
IPC: H01L21/677
Filed: 1990-09-25
Abstract: PURPOSE:To prevent dirtying of the rear surface of wafer and the accumulation of dust by using a linear motor, 'TeflonR' disk carrier, and 'TeflonR' coated electromagnet. CONSTITUTION:An approximately 5mm thick 'TeflonR' disk 2 is used as a wafer carrier in which a rare earth magnet 5 and an approximately 1mm thick aluminum board 7 are incorporated. The rare earth magnet is an SmCo5 type with a large maximum energy capacity (BH)max and these magnets are placed in a circular format around the perimeter of the 'TeflonR' disk 2 so as to have reverse polarity to the magnetic flotation electromagnet 3 and the lengthwise direction space maintenance electromagnet 4. This combination of magnets and electromagnets keeps the 'TeflonR' disk at a distance of about 1-5mm away from the various electromagnets. The magnetic field produced by the alternating electric current flowing into the propulsion force producing coil and the eddy current produced by the aluminum board surface produce a propulsion force according to Fleming's law and the 'TeflonR' disk which holds the wafer 1 is transported. Also, if coating fluid from the resist coating process happens to make its way to the bottom surface of the carrier and attach to the carrier, it can easily be washed away.

Title: Optical disk, checking device and recording device
Inventor: OZAKI KAZUHISA
IPC: G11B7/24097
Filed: 1994-09-22
Abstract: PURPOSE:To effectively prevent unauthorized copying of a disk. CONSTITUTION:The figure (A) shows the shape of the wobbling pit of a disk and the figure (B) shows a tracking error. In the normal arrangement of the pit on the left-hand side, the center line of the pit is coincident with the center line of a track. On the other hand, in the part of a singular pit train on the right hand side, both center lines are deviated and the center of the pit is wobbled. When the tracking error for these arrangement is obtained by means of a pickup having spots S1-S3, the reflected light quantities of the spots S1 and S3 are nearly equal on the left-hand part and a tracking error signal becomes '0'. However, on the right-hand part, the reflected light quantities of the spots S1 and S3 are unbalance and the tracking error signal is increased in proportion to the deviation from the virtual center line of track. Consequently, when the part in which the pit train is wobbled is reproduced, a tracking error signal superimposed with a wobble signal is obtained.

Title: Overwriting method
Inventor: KOBAYASHI TADASHI
IPC: G11B7/30
Filed: 1989-09-29
Abstract: PURPOSE:To remarkably improve erasability by superimposing a light beam pulse for a second level having a higher power on a first level having the lower power to melt a recording layer. CONSTITUTION:A light beam pulse for a second level having a higher power is superimposed on a first level having the lower power to melt a recording layer. Namely, an erasing level is kept at a temp. above the melting temp. of the recording layer, the recording level is held at the high temp., and overwriting is carried out. Although the erasing and recording levels are heated above the melting temp. of the recording layer in this way to melt the part of the recording layer to be irradiated with the beam, the cooling rates differ from each other because the part which is irradiated with the beam at the erasing level differs in cooling rate from the part which is irradiated with the beam at the recording level, and consequently both parts have a different crystal structure and a single-beam overwriting is attained. Namely, since the recording layer is melted by the beam at the erasing level, the phase is completely changed, and unerased parts are hardly left. Therefore, the erasability is remarkably improved.
