Abstract: PURPOSE:To improve the positioning accuracy of plural heads on an information recording medium by fixing an end of a support shaft to an actuator housing through a support member made of a material having a different thermal expansion coefficient from that of the actuator housing. CONSTITUTION:Suppose that a deformation causing a tilt approaching the turning center axis A of a magnetic disk 6 at a side remote from a base 5 of an actuator housing 1 is caused at a high temperature from a low temperature, the thermal expansion of the material of a flange member 22 is selected to be larger than the thermal expansion rate of the material of the actuator housing 1 and the flange is fixed only at a part P.

IPC: G06F17/50
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To sort the loop of dependence relation among data while executing detection. SOLUTION: When data of a logical circuit is inputted (S101), the number (total) of gates in the logical circuit is measured (S102) and the number(dependence number) of the gates for outputting the input signal is set concerning the respective gates (S103). Then, data concerning the gate where the dependence number is zero is added to a queue (S104). When data exists in the queue (S105), data concerning the gate is read from the queue (S106), one is subtracted from the total (S107) and the dependence numbers of the gate for inputting the output signal is subtracted by one (S108). Data concerning the gate where the dependence number newly becomes zero is added to the queue (S104).  When data is lost in the queue (S105), the output of data concerning the gate or the output of data indicating loop detection is executed in order of output from the queue (S110 and S111) in accordance with whether the total is zero or not (S109).

Title: Optical semiconductor device
Inventor: OKUDA MASAHIRO
IPC: H01L29/778
Filed: 1991-05-21
Abstract: PURPOSE:To obtain an optical semiconductor device which is used for changing the mobility of electrons of photodetectors, optical gate transistors, etc. CONSTITUTION:A channel section 2 having a quantum well structure and semiconductor cap layer 10 are formed on a semiconductor substrate 1. At the center of the layer 10, a ridge which acts as a waveguide for propagating incident light 3 is formed along the incident direction of the light 3. A source and drain electrodes 6 and 7 are respectively formed on both sides of the ridge of the layer 10. The mobility of electrons propagated through the channel section 2 is modulated by causing the transition of electrons between quantum levels in a quantum enclosing structure which encloses the electrons by irradiating the channel section 2 of the quantum enclosing structure with light. Thus the current flowing between the source and drain electrodes 6 and 7 is modulated.

Title: Clock generation circuit
Inventor: KATO TSUTOMU
IPC: H03K5/00
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To shorten the time from power supply to clock output start. SOLUTION: When a power is supplied, since the flip-flops FR1-FRm of a counter circuit 5 are reset by reset signals from a power ON reset circuit 6 and switching signals are turned to 'L', a switching circuit 4 supplies frequency divided clocks for which high-speed oscillation clocks from a high-speed oscillation circuit 2 are frequency divided to the oscillation number frequency of a low-speed oscillation circuit by a frequency divder circuit 3 to a peripheral circuit. Then, when the low-speed oscillation circuit 1 starts oscillation, the low-speed oscillation clocks are inputted to the counter circuit 5 and the counter circuit 5 counts the clock number of the low-speed oscillation clocks by the FR1-FRm. When the prescribed number is counted, since the inverted output terminal QB of the FRm is changed from 'L' to 'H', the switching signals are changed from 'L' to 'H'.  Thus, the switching circuit 4 switches supply clocks to the respective peripheral circuits from the frequency divded clocks to the low-speed oscillation clocks.

Title: Preparation of ferromagnetic powder
Inventor: SUEYOSHI TOSHINOBU
IPC: G11B5/706
Filed: 1978-11-25
Abstract: PURPOSE: To reduce dispersion in coercive force by forming layer of cobalt-containing iron oxide layer on magnetic iron oxide powder in an alcohol solvent.  
     CONSTITUTION: Cobalt chloride and ferrous chloride are dissolved into a water soluble alcohol such as polyethylene glycol. Acicular iron oxide is dispersed into the solution, and dispersed solution is added with an aqueous solution containing an equivalent or more of alkali. The dispersion is then mixed at a temperature below its boiling point and filtered to separate out the magnetic powder. In this process, the cobalt chloride and ferrous chloride dissolved in the alcohol are precipitated out by the added alkali and deposited on the iron oxide magnetic powder as Co(OH) 2  and Fe(OH) 2 . The precipitated Co(OH) 2  and Fe(OH) 2  on the powder is allowed to have a better balance and more uniform distribution by the use of alcohol solvent than use of water. Further, an excellent powder dispersion assures uniformly distributed magnetic powder. Thus, uniform reaction is caused to occur, providing magnetic powder having narrower coercive force distribution.

Filed: 1994-06-28
Abstract: PURPOSE:To prevent the white stripe of an image by applying the vibration of frequency equal to or above a specified value to a brush for electrification by a piezoelectric element. CONSTITUTION:In this electrifying device, a brush 1 consisting of rayon conductive fiber is fixed to a mounting bracket 2 made of aluminum with conductive adhesive and the piezoeletric element 3 is fixed on the back surface of the bracket 2. The brush 1 is brought into contact with a photoreceptor 4 so as to impress DC voltage on the brush 1 from a power source, and the DC voltage is impressed on a developing roller. By impressing AC voltage on the piezoelectric element 3, in such a state, the vibration of the frequency of >=50Hz is imparted to the brush 1. As a result, the dispersion range of the surface potential of the photoreceptor 4 is restrained to <=200V, and the vertical stripe in the image is prevented. Furthermore, toner and paper powder are shaken off by the vibration of the brush, thereby preventing the adhesion of a foreign matter and prolonging the life of the brush.

Abstract: PURPOSE:To always attain excellent transmission and reception without a dip of a radio wave even at any point by providing a transmission timing control means switching a 1st transmission signal sent in a 1st carrier and a 2nd transmission signal sent in a 2nd carrier in time sharing. CONSTITUTION:A 1st carrier frequency f1 and a 2nd carrier frequency f2 are provided to upper and lower of a local frequency fL.
