Title: Password code recognizing circuit
Inventor: WADA MOTOHARU
IPC: G06F21/00
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To make a security check by hardware by regarding the frequency of depression of a power switch as a password code and electrifying the whole device when passing security inspection by the password code. SOLUTION: A switch operation monitor circuit 10 counts an arbitrary operation frequency of the power switch 4 and shows a user that a one-digit number has been recognized through a display part control circuit 50 and an operation state display part 3 by making an LED 9 illuminate in red for one second. This operation is repeated as many times as the digits of the password code and all the digits after being inputted are transferred by the switch operation monitor circuit 10 to a password code comparing circuit 20. The password code comparing circuit 20 compares the inputted password code with the password code which is already registered in a password code memory 40.  When they match each other, the comparing circuit 20 requests a power control circuit 2 to supply the electric power to a computer circuit 7 and the power control circuit 2 starts supplying the electric power to the computer circuit 7.

Title: Resonance type switching power unit with ac-dc dual standby power source
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 1990-06-28
Abstract: PURPOSE:To obtain a standby power source with a constitution which uses a less number of parts commonly used by a main power source also by obtaining the DC output voltage of the standby power source from the secondary winding output of a power source output controlling transformer commonly used by the main power source and making the DC output voltage of the standby power source constant by continuing the inductance control on the power source output controlling transformer even in a standby state. CONSTITUTION:A DC output voltage for a standby power source and a DC voltage for a signal processing circuit are obtained by rectifying high-frequency power from secondary winding N21. When the DC voltage for the signal processing circuit is cut off and a horizontal deflection output circuit 8 stops operation in such state, the DC output voltage line outputted from secondary winding N22 becomes a no-load state. The load viewed from a power source output transformer containing a PRT 3 and control amplifier 5 becomes the DC output voltage of the standby power source only. Since the fluctuation of a DC output voltage caused by the fluctuation of an DC input voltage is inputted to the amplifier 5 even in such state, the DC output voltage of the standby power source is made constant. Therefore, the number of used parts and cost of this switching power unit can be reduced.

Title: Preamplifier circuit
Inventor: NOGAMI MASAMICHI
IPC: H04B10/07
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration of pulse width and to attain proper optical communication by providing a constitution, where a differential input/output type differential amplifier means converts a current signal into a voltage signal, a generator means generates a midpoint potential between the positive and negative phase outputs of the differential amplifier means, and a 1st feedback load means is placed between the output terminal of the generator means and the negative phase input terminal of the differential amplifier means. SOLUTION: A differential amplifier 2 outputs positive and negative phase outputs, in response to an input signal. A midpoint potential generating circuit 4 inputs the positive and negative phase outputs and generates a midpoint potential between these phase outputs. A feedback resistance 5 feeds the midpoint potential back to the negative phase input terminal of the amplifier 2. Then the threshold voltage of the midpoint potential becomes equal to 0 level of the input signal to attain an operation that uses the linear region of the amplifier 2 to its maximum. As a result, the distortion of output duty is reduced despite the presence of a large input signal near the largest light receiving power.

Abstract: PURPOSE:To obtain a single crystal having a very low concentration of contained carbon and suitable of high-speed integrated circuits, etc., by controlling the CO concentration in an inert gas in a chamber at a specific value or below in producing a compound semiconductor single crystal by the liquid- encapsulated pulling up method. CONSTITUTION:A compound semiconductor single crystal, e.g. GaAs single crystal or InP single crystal is produced by the liquid-encapsulated pulling up method. In the process, the carbon monoxide concentration in an inert gas in a chamber of a pulling up machine is controlled at <=1,000ppm by a method for intermittently or continuously replacing the inert gas in the chamber of the pulling up machine before starting or during the pulling up of the single crystal. Thereby, the aimed compound semiconductor single crystal having <=1.0X10<15>atoms/cm<3> carbon concentration contained in the crystal is obtained. The resultant single crystal has a very low carbon concentration contained as an impurity, and therefore assumes no electrical activity.

Title: Digital control correction method applying finite setting input of bang-bang control
Inventor: IWASHIRO MASAFUMI
IPC: G05D3/12
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a correction method applying the finite setting input of bang-bang control to reach an optional target position for the digital control. SOLUTION: The current input state is not a finite setting state in a control process of the seek control that is carried out for each sampling (S4) nor an acceleration state of the bang-bang control (S5). In other words, the input state is equal to a deceleration state. Under such conditions, the finite setting input is calculated (S7). If the value of all calculated finite setting inputs satisfy the input limit (S8), the deceleration state of bang-bang control is switched to the finite setting input (S10). Thereafter, the finite setting inputs are successively inputted for each sampling (S4, S10).
