Title: Polishing pad, polishing device and method
Inventor: NAKAJIMA HIDEHARU
IPC: B24B37/22
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To restrain scattering in a polishing rate and amount by forming in a polishing pad a through opening for supplying polishing slurry to a surface to be polished from a surface side facing a polishing face of the pad. SOLUTION: Polishing slurry is supplied to a surface of wafer to be polished from a polishing slurry main supply pipe 23 through a polishing slurry auxiliary supply pipe 22 and a through hole 21 formed at a polishing pad base 20. Thus the slurry is supplied to the polished surface from a surface side facing a polishing face of a polishing pad via the through hole 21, whereby the slurry is evenly supplied to the surface of wafer to be polished even though a pressing force is applied thereonto. Accordingly, the polishing slurry sufficient for chemical and mechanical polishing can be ensured, and scattering in a polishing rate and amount between wafers and in a plane of wafer can be restrained.

Title: Floating type magnetic head
Inventor: SHIROKURA TAKAAKI
IPC: G11B5/60
Filed: 1980-07-11
Abstract: PURPOSE:To utilize the partial pressure of air flow in the shortsize direction of a slider at a maximum by selecting the polishing angle of the slider flank of a magnetic head, used in a disk device having a rotary actuator, so that components of floating force by the air flow are maximized. CONSTITUTION:A disk 11 rotates on a position 12, and the actuator of a magnetic head 15 on a position 13. As the actuator rotates, an angle between the peripheral speed direction of air flow generated through the rotation of the disk 11 and the long-size direction of a slider 6, i.e., yaw angle thetar14 varies. Floating force operates upon the slider 6 by separating into the slider long-size direction component 18 of floating force and the slider short-size direction component 19 in the peripheral speed direction 17 of the air flow. The extent of floating at a slider flank polishing angle alpha when the peripheral speed of the air flow is 30m/s and thetar is 10 deg. is as shown in the figure. Therefore, such a small polishing angle alpha results in that the degree of a decrease in floating force with an increase in yaw angle thetar is reduced.

Title: Ghost removing device
Inventor: TAKAGUCHI TATSUYUKI
IPC: H03H15/00
Filed: 1989-04-13
Abstract: PURPOSE:To shorten time required for removing a ghost by dividing a tap gain train into plural sections, and performing ghost removing operation while changing successively tap gain by changing the conversion factor of tap gain train determination for every section. CONSTITUTION:A section discrimination table 26 which inputs the conversion factor set by a factor setting circuit 16, and discriminates the section of the tap gain in conformity to the same train number as the train number for an error train memory 21, and gives more correction to the conversion factor for every section is provided. Then, an error signal train read out from the error train memory 21 is multiplied by the corrected conversion factor by a multiplier 23. Thus, since convergence in the vicinity of a center tap is accelerated, waveform equalization comes to be finished early, and the renewal of the tap for a usual ghost due to the influence of the waveform equalization, etc., becomes unnecessary, and the time required for removing the ghost can be shortened.

Title: Liquid phase epitaxy method
Inventor: SAGAWA TOSHIO
IPC: H01L21/208
Filed: 1987-04-17
Abstract: PURPOSE:To decrease contamination of a reacting pipe and to obtain a compound semiconductor crystal including P-type gallium, whose characteristics are stabilized, by adding zinc for eutectic alloy of gallium and zinc. CONSTITUTION:In zinc alloy having eutectic composition, the composition of zinc in the entire eutectic alloy is always constant. When the required adding amount of the zinc is found, the required amount of the eutectic alloy can be simply computed. The alloy can be readily manufactured. The alloy is made to be a pellet and it is used as the impurity source of the zinc. The pellet is set on a graphite boat together with gallium arsenide crystal, gallium and aluminum. Then a P-type Ga-Al-As compound is grown on the gallium arsenide crystal. Thus contamination of a reacting pipe with zinc during the crystal growth becomes remarkably less. Explosion due to clogging of the pipes and the like are suppressed and danger is reduced. The uniformity in characteristics of a compound semiconductor crystal including Ga can be improved.

Abstract: PURPOSE: To provide an H-DOT for scale reduction in network implementation. CONSTITUTION: The H-DOT approach can execute one of several mesh configurations based on two-port fundamental elements of the same. H-DOT uses two or more links between two points and combines their functions to form one network having two or more systems and attachments. For example, in a twodimensional mesh, two adjacent north-south links and two adjacent east-west links are coupled to form one network having four processing elements and attachments. When the H-DOT approach is used, a processing element is connected to the next processing element by a link providing two vertical routes and two horizontal routes for an apparently H-shaped connection link with respect to mutual connection of processing elements, and dot OR operation is performed with respect to other mutual connection of arrays.

Title: Head position control system by tracking servo for magnetic recording/reproducing device
Inventor: HASHIMOTO KUNIHIRO
IPC: G11B5/58
Filed: 1987-04-20
Abstract: PURPOSE:To avoid such a case where the head position accuracy is affected by the position accuracy of servo data by providing two servo heads at both front sides of a primary head so that they touch a track and also are put on the track by the same extent, detecting a head position error signal from the signals detected by said servo heads, and using the detected error signal to control the head position. CONSTITUTION:Two servo heads are set at both front sides of a primary head D0 like a R/W head, etc., so that these heads touch a track and also are put on the track by the same extent. Thus the primary head D0 position is controlled by a deviation signals between both servo heads. In other words, an oblique line part shown in a figure is put on a track T2 when the primary head D0 has a track shift. Thus the signals sent from both servo heads change in proportion to the overlapping amount between the head D0 and a data part in case the head has a shift. These changed signals are detected and controlled so that they are equal to each other. In such a way, the head D0, e.g., the R/W head can be controlled to the best position.

Title: Light receiving circuit
Inventor: OKAMURA MASAHIRO
IPC: H04B10/40
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To attain an excellent S/N ratio even when the light receiving circuit is in use at a location where it is exposed under the direct sun light outdoors by employing a series circuit consisting of a 1st light receiving element and of a parallel connection circuit comprising a resistor and a 2nd light emitting element with a larger light receiving area than that of the 1st light receiving element for the light receiving circuit. SOLUTION: A 1st light receiving element 1 has a sufficient response speed to receive a signal light. A 2nd light receiving element 2 connected in series with the 1st light receiving element 1 and in parallel with a resistor has a wider light receiving area than that of the 1st light receiving element and a higher electromotive force when a background light is made incident onto the 2nd light receiving element. Furthermore, a light receiving element whose response speed is slower than the speed of the signal light and that responds insufficiently to the incidence of the signal light is adopted for the 2nd light receiving element 2. In the case that a background light much more intensive than the signal light is made incident, a current in response to the background light is produced even in the 2nd light receiving element 2.  Through the constitution above, in the case that the background light is made incident, a reverse bias voltage applied to the 1st light receiving element 1 is increased.
