Patent JP-S59117761-A (JP)
Title: Positioning system of head
Inventor: YAMADA TAKEHITO
IPC: G11B21/10
Filed: 1982-12-24
Abstract: PURPOSE:To attain high speed and accurate head positioning even if the turning speed of a recording medium is slow by using a servo pattern of each track and a sector servo pattern. CONSTITUTION:A microcomputer 20 outputs a required speed pattern signal in response to a set object position and present position of a head 11. The speed is feedback-controlled with an actuator 17 by an error between this signal and a real speed via a timer 19 or the like by the detection of the 1st servo pattern recorded in circumferential direction at each track group such as the ten tracks of a recorder 10 like a disc or the like by a detecting circuit 18 and the head 11 is moved in high speed. Further, the speed of a head 11 is brought to a constant low speed by the 1st pattern detection of the objective track group and even if the turning speed of the device 10 is slow by peak hold circuits 13a- 13d, the sector servo pattern is detected surely and the head 11 is positioned to the object track. Thus, even if the speed of the recording medium is slow, the positioning of the head is attained accurately in high speed.

IPC: G03G15/08
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To stably increase and keep the quantity of electric charges on a developer by forming an electrostatic charge adjusting layer containing a siloxane crosslinked acrylic resin obtained by crosslinking and hardening an alkoxysilyl-containing acrylic copolymer on the surface of the contact part of a supporting member brought into contact with a developer support.

Title: Control power guarantee type of protective current against overcurrent
Inventor: KATO SHINOBU
IPC: H02H3/08
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To add control of preventing the overheat breakage of a semiconductor device for current limitation at the occurrence of an overcurrent, and prevent the voltage loss inside a circuit, in the stationary current range which is not more than the set current, in a protective circuit against overcurrent of a two-point connection type, such that it is merely inserted in series into the electrical path which protects from overcurrent. SOLUTION: An overcurrent state is detected with a current detection resistor, and the gate voltage of a power MOS FET 1 is lowered by the operation of a transistor 2. Using the voltage between a source and a drain which rose risen thereby as the voltage and detected voltage, causes a Schmitt trigger circuit 8 to be operated to instantaneously lower the gate voltage and a power MOS FET 1 to shift into 'OFF' condition. Next, a Schmitt trigger circuit 10 detects the 'OFF' condition and generates the reset signal of 'OFF' condition of the power MOS FET 1 after a preset time. In a stationary current region set with the current smaller than an overcurrent, the gate drive voltage of the power MOS FET generates the voltage under 1 V between A and B which become the voltage loss of this protective circuit against overvoltage, utilizing an astable multivibrator and a transformer.

Filed: 1993-09-13
Abstract: PURPOSE:To efficiently dissolve metallic copper without volatilizing harmful ammonium by using an aq. soln. contg. ammonium bicarbonate and a specified oxidizing agent as a solvent for metallic copper. CONSTITUTION:Metallic copper is deposited as scales in the operated steam generator of a pressurized water reactor or thermal electric power plant to decrease the heat conduction and to lower heat efficiency, and consequently the scales are dissolved off. An aq. soln. contg. 1-15wt.% of ammonium bicarbonate (NH4HCO3), kept at pH7.8, added with 0.03-0.5wt.% of hydrogen peroxide or 0.3wt.% of ammonium persulfate as an oxidizing agent and with the weight ratio of hydrogen peroxide to ammonium bicarbonate controlled to 0.02 to 0.1 is used as a solvent for the metallic copper scales. Consequently, gaseous ammonium is not produced, hence the working envuronment is not worsened and metallic copper is rapidly dissolved off.

Title: Speed detector for dc linear motor
Inventor: INAGAKI HIROSHI
IPC: H02P29/00
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a speed detector for a DC linear motor, which can detect the speed accurately. SOLUTION: A current switching detector generates pulses in correspondene with the change in current flowing through a stringing 30, and a microcomputer operates the speed of a movable piece 50 from the time interval of the pulses. At this time, the microcomputer inhibits the counting in an inhibit time t1 after the counting of the pulses Pa at the falling time (timing (a)) of the current of the stringing. Therefore, the microcomputer does not count the pulses Pb even if the pulses Pb at the current rising time (timing (b)) are inputted after the counting of the pulses Pa. Therefore, the speed of the movable piece 50 can be detected accurately.
