Title: Defective sector managing system
Inventor: TAKAHASHI KENJI
IPC: G11B20/18
Filed: 1984-02-28
Abstract: PURPOSE:To attain effective use of a sector by recording information outputted from an operation environment detecting means to a prescribed location of a defective sector if a defective sector takes place. CONSTITUTION:While a main program handles a sector A as a normal section, a data is inputted from an input 1. The data is written in the sector A in the step S1 for read check, and when it is discriminated in the step S2 that an error is caused, the step goes to the S3, where the operating environment data is read from a PIA. The defective sector flag of the sector A is set in the S4 and the operating environment data when an error is caused is recorded on a recording section. The substituting processing of the sector A is attained in the S5. When the operator gives a command to restore the defective sector of a series possible for restoration, the data write processing is inputted from an input 2. The input 2 goes to the S7 via the S1 and S2. The sector defective flag of the sector A is reset in the S7. The substitute restoring processing from the substitute sector to the sector A is attained in the S8. Thus, the sector A is used as the mormal sector further.

Title: Refill of ball point pen
Inventor: KOBAYASHI SEIICHI
IPC: B43K1/08
Filed: 1994-02-09
Abstract: PURPOSE:To effectively prevent a counterflow of ink caused at the time of writing in an upward posture of the ball point pen by loosely fitting a shaft- shaped piece having a taper to seat on a piece receiver at its rear end, and having an ink introduction groove and small diameter portion at the appropriate front outer periphery in a space permitting communication between a valve chamber and a tip inner bore. CONSTITUTION:In a condition of the chip 5 directed downward prior to writing, a piece 15 is in contact with a tip end ball 5a in its small diameter portion 18, and ink 22 that comes into a chamber 13 from an ink containing pipe 4 via an introduction hole 21 is conducted to the rear end of a tip end ball 5a through the introduction groove 16 of the piece 15. At this time, the tip end ball 5a is pressed and put into close contact with a caulked portion at its small diameter portion 18, so that direct flow is prevented. On the other hand, when the chip 5 is directed upward, the taper portion 17 of the piece 15 comes into close contact with a piece receiving seat 19 so as to seal the introduction hole 21, thus the counterflow of ink can be prevented through a head even in the case where ink beneath the tip end ball 5a is absent during upward posture writing.

Title: Active circuit and oscillation circuit
Inventor: NAGASAWA SATOSHI
IPC: H03B5/12
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To provide the active circuit that reduces side band noise based on low frequency noise in the vicinity of DC and to provide the oscillation circuit that is oscillated by the active circuit. SOLUTION: A circuit that reduces an impedance at a low frequency in the vicinity of DC without giving effect on a DC circuit and high frequency oscillation is provided to an input side of the oscillation circuit. Since low frequency noise in the vicinity of DC is led to ground through a choke coil (L1 ) 12 and a capacitor (C3 ) 13, a noise voltage applied to a base of a transistor(TR) 6 is reduced. As a result, side band noise produced at an emitter of the TR 6 by the low frequency noise in the vicinity of DC is reduced.

Abstract: PURPOSE:To widen the operating temperature range by constituting the title attenuator with an IC chip integrating two T type attenuators and one FET, a DC bias control circuit and a nonlinear correction circuit. CONSTITUTION:A differential amplifier circuit 7 amplifies a difference between a signal and a reference voltage ES, a bias voltage VP of a gate GP of a FET connecting in parallel with a mirror attenuator 2 is varied to vary a resistance of a FETP connected in parallel so that a voltage V6 at a terminal 6 is the same as the reference voltage ES. Thus, the relation between the resistance of two FETS connected in series and the resistance of the PETP connected in parallel with the two FETS is changed in the relation so that the voltage V6 at the terminal 6 is always constant, and the characteristic impedance of the T type mirror attenuator is constant. The T type FET of the signal attenuator is constituted in a same IC chip of the mirror attenuator and since a gate of the series FETS is connected in common respectively to the gate of the parallel FET, each internal resistor, that is, the attenuator characteristic is the same for both the attenuators. Thus, operating temperature range is widened.
