Title: Actuator driving circuit for optical disk reproducing device
Inventor: MATSUSHIMA HIROYUKI
IPC: G11B7/09
Filed: 1987-05-20
Abstract: PURPOSE:To prevent destruction of an actuator, by turning off a switch means when the output of a supply voltage circuit enters into the short-circuit or open state. CONSTITUTION:When an output 15 of a supply voltage circuit 14 enters into the short-circuit or open state an NPN transistor 32 and a PNP TR 34 are turned off and a PNP TR 35 and an NPN TR 37 are turned off also because an NPN TR 29 is turned on. Consequently, a supply voltage is not inputted to an actuator driving circuit part 4. When an output 16 is short-circuited or opened, a PNP TR 22 and the NPN TR 29 are turned off and the NPN TR 32 or the like is turned off, and therefore, the same operation state is set. When an output 18 is short-circuited or opened, the PNP TR 22 of a detecting circuit 19 is turned off and the NPN TR 29 is turned on, and therefore, a switch circuit part 31 is set to the same operation state. Thus an excessive current does not flow to the actuator to prevent destruction of the actuator.

Title: Optical disk examining device
Inventor: HANAKAWA EIICHI
IPC: G11B7/00
Filed: 1984-06-13
Abstract: PURPOSE:To detect surely defects other than pits on the surface of a disk by detecting rugged flaws other than pits on the surface of the optical disk with a photodetector and a comparator. CONSTITUTION:If a defect exists on the surface of a disk 1', a photodetector 6a which has a maximum value of the quantity of reflected light due to this defect receives almost all of the quantity of reflected light due to the defect. The quantity of a diffracted light A' due to diffraction of a pit on the disk 1' is little because the light receiving area of the photodetector 6a is small. Thus, a ratio of the quantity of diffracted light due to the defect to the photodetector 6a to the quantity of diffracted light due to the pit to the photodetector 6a is made higher to improve the S/N. Only the output of the photodetector 6a is outputted to a logical adder 9 with a high S/N if the output of the photodetector 6a corresponding to the maximum value of the reflected light due to the defect is higher than a set voltage of a comparator 8, and thus, defects other than pits on the surface of the disk are detected surely.

Title: Method of removing impurity from iron oxide
Inventor: SHIMAZAKI MITSUMASA
IPC: C01G49/02
Filed: 1985-06-06
Abstract: PURPOSE:To remove impurities so that a magnetic material of oxide is obtained, by grinding an iron oxide containing low-density admixed impurities, dispersing or suspending the ground iron oxide mixed with an electrolyte and surface active agent and separating the suspension into a precipitate layer of the concentrated iron oxide and a suspension layer of the concentrated admixed impurities. CONSTITUTION:An iron oxide containing admixed impurities such as oxides of Si, Al, and Ca, or silicate, etc. having a lower density than iron oxide is ground, dispersed and suspended in water containing an electrolyte (e.g., conc. hydrochloric acid, etc.) and a surface active agent. The suspension is separated into a precipitate layer of the concentrated iron oxide and a suspension layer of the concentrated admixed impurities, so that the impurities are removed from the iron oxide. By this method, an iron oxide raw material such as an ore which can not be used directly as it is because of a large amount of admixed impurities contained can be used as a raw material iron oxide for a magnetic material of oxide by removing the impurities from the iron oxide raw material.

Filed: 1983-07-05
Abstract: PURPOSE:To bear a large bender force and to enlarge a shape controlling range by dividing a roll chock of work roll into an inside roll chock and an outside one. CONSTITUTION:The inner rings of a No.1 roller bearing 2 and a No.2 roller bearing 3 mounted on an inside roll chock 5 are constructed to be free from a work roll 1.

Filed: 1989-05-18
Abstract: PURPOSE:To hinder occurrences of burrs by forming a tungsten silicide film between an aluminum alloy film and a photoresist and chamfering the above tungsten silicide film after etching it into a groove like shape. CONSTITUTION:A tungsten silicide film 10 having the thickness of 0.01-0.2mum is formed between an aluminum alloy film 3 and a photoresist 4. The film 10 is a compound which is composed of elements in such a way that a temperature which allows molecular vapor pressure of the elements to attains 1Torr is lower than the temperature of a semiconductor device in the midst of etching. In this way, when the dry etching of the film 10 is performed in an etching chamber, its line width becomes thinner than that of the photoresist 4. In such a case, the film 10 is etched selectively according to conditions of the temperature and vapor pressure. Subsequently, if dry etching is performed on condition that the thickness of the film is 0.01-0.2mum and etching is performed into a groove like shape, an aluminum wiring layer 5 on which upper edges are chamfered is obtained and occurrences of burrs are prevented.
