Title: Gain control circuit
Inventor: TOKUDA KAZUO
IPC: H03G1/00
Filed: 1980-09-10
Abstract: PURPOSE:To decrease the number of transistor elements and to save current consumption, by commonly using a current source for current compensation and a differential transistor, in gain control of a plurality of input signals at the same time. CONSTITUTION:A collector current of a transistor (TR) 3 flows as a collector current of a TR22 by a current Miller circuit 24. The difference between the collector currents of TRs 2 and 22 flows to a load 16, and when both collector currents are equal, that is, no input signal is applied, a current difference is zero and a voltage from a bias voltage source 21 is given to the base of a TR17 and this becomes the operating point for the output. The operating point of the output of the TRs 2, 3 can be kept constant even in any state of a gain control by a DC voltage applied to terminals 14 and 15, and an output signal in gain control can be obtained at the load resistor 16.

Title: Magnetic head
Inventor: TAKAYANAGI KAZUTOSHI
IPC: G11B5/60
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head which can improve adhering operability for a slider and a magnetic shield member and maintain excellent adhesive strength and is reducible in thickness. SOLUTION: An edge cut 32 is made in the side edge part of a slider 3 on the side of a join part T. When an adhesive is applied, part of the adhesive stays in the edge cut 32. The adhesive in the edge cut 32 also contributes to joining between the slider 3 and magnetic shield member and then the adhesive strength between the slider 3 and magnetic shield member 4 becomes larger. Further, the adhesive stays in the edge cut 32 to suppress a shift of the adhesive to the slide surface 3a of the slider 3. It is not necessary to pay attention to sticking of the adhesive on the slider 3 when the adhesive is applied and coating operability is improved.  Of an upper edge size difference area 4a1 , the part on the side of an outer peripheral wall 3b of the slider 3 is usable as an effective coating area, and consequently the upper edge size difference area 4a1 is made narrow to make the device small-sized.

Title: Initiation/termination hole detecting circuit for 1/4-inch cartridge tape
Inventor: UMEGAKI SUNAO
IPC: G11B15/08
Filed: 1989-05-19
Abstract: PURPOSE:To always detect the holes drilled through a tape by securing the intermittent emission of light via a light emitting diode. CONSTITUTION:When a hole of a tape is kept between a light emitting diode 1 and a phototransistor 2, the terminal voltage of a load resistance 3 rises up together with the output voltage of a high-pass filter (HPF) 4. When the output voltage of the HPF 4 exceeds the reference voltage VREF, the output of a comparator 5 is inverted to output the detection of the hole to the outside. A control circuit drives intermittently the diode 1 and therefore a capacitor of the HPF 4 repeats the charging/discharging actions. Then the electric charge stored during the emission of light of the diode 1 is discharged in an OFF state of the diode 1. Therefore the correct detection output is always obtained in a hole detection state. As a result, the holes drilled through the tape can be detected in any state.

Title: Image reader
Inventor: HOKOI ITSUHITO
IPC: H04N5/359
Filed: 1994-05-16
Abstract: PURPOSE:To improve the S/N by identifying an effective original area with a method optimum to various originals to set the exposure to the effective area and to suppress gradation-jump by optimizing the amplification factor of analog signal amplification. CONSTITUTION:An original effective area B and the read enable area A of an original are detected based on image information obtained by reading tentatively the original 1 with a set initial value and stored in a memory 10 and exposure is calculated by maximum luminance a(b) of the area A(B). In this case, the S/N is minimized by adjusting the exposure depending on the image pickup condition based on three factors as the luminous quantity of a light source 2, an aperture 3 and the storage time of a CCD 5 so that the effective original area B is set within the dynamic range of the CCD 5. Then the amplification factor of an analog signal amplifier 6 is obtained based on the maximum luminance of the original valid area so as to obtain the range equal to an input full range of an A/D converter 7 thereby obtaining smooth gradation expression without gradation jump by fully utilizing the input range of the A/D converter.

Title: Semiconductor memory device
Inventor: SASAMOTO YOSHIFUMI
IPC: G11C29/04
Filed: 1983-07-11
Abstract: PURPOSE:To improve the reliability of a semiconductor nonvolatile memory device by checking or checking/correcting stored information when the state is transited from the storage holding state to the external access enable state. CONSTITUTION:When an external current supply is interrupted, a current is supplied to a memory section 1 from a battery 7 as a backup power supply so as to prevent the volatility of stored information in the memory section 1. When the external power supply is restored, a current is supplied to other circuits from a power supply section 6 and the state becomes the electrically accessible state. The storage information in the memory section 1 is checked by the state changeover. That is, when a power supply confirming signal is given from the power supply section 6, a main control circuit 5 sets an address counter 4 to an initial value, counts up sequentially the address so as to read the storage information of the memory section 1. A parity check circuit 3 checks the content at the same time. When no error exists in the storage information, the state is transited to the externally accessible state at a point of time when the check of the content of all the memories is finished. If there exists any error, it is regarded that the storage information in the memory section 1 is destroyed and the main control circuit raises alarm information to an external device.

IPC: B81B3/00
Filed: 1993-05-27
Abstract: PURPOSE:To provide an electrostatic actuator which can prevent the wiring troubles and insufficient expanding and contracting operations of the actuator by wiring. CONSTITUTION:Electrode plates 2 and 3 have spiral shapes and are counterposed to each other in their axial direction. The plates 2 and 3 are respectively coated with insulating films. One end section 2a of the plate 2 is connected to its corresponding one end section of the plate 3 with an insulator 4 and the other end section 2b of the plate 2 is connected to its corresponding other end section 3b with another insulator 5. When a voltage is applied across the plates 2 and 3, an electrostatic attraction is generated between the plates 2 and 3 and displaces the the plates 2 and 3 in the direction in which the gap interval (d) between the plates 2 and 3 is reduced against the spring forces the plates 2 and 3 themselves have so that, for example, the free insulator 4 can be brought nearer to the fixed insulator 5. When the application of the voltage is discontinued, the plates 2 and 3 are displaced in the direction in which the gap interval (d) is restored and return to their original positions due to the spring restoring forces the plates 2 and 3 themselves have.
