Title: Cdma receiver
Inventor: HATA YOSHIYUKI
IPC: H04B1/707
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of noise originating from the characteristic of a filter for feedback control when the power of a signal received by a DMA system (multi-rate spread CDMA communication system) using a plurality of chip rates is amplified to a target magnitude. SOLUTION: Part of a reception signal amplified by a variable amplifier 1 is obtained by a coupler 2 and a filter 3 having a characteristic of making only the signal of not more than a band corresponding to the lowest rate pass through limits the band of the part of the signal. A detection means 4 detects the power of the signal. Storage means 5-7 add signal power which is lost in the band limitation and store a control target value, which realizes the target value, corresponding to the detection value of the detection means for each chip rate. A selection means 8 selects the control target value corresponding to the rate of the reception signal. Control means 9-11 control a variable amplifier so that the detection value of the detection means 4 is made closer to the selected control target value.

Title: Drive circuit for semiconductor switch
Inventor: OYA TETSUJI
IPC: H03K17/08
Filed: 1993-02-22
Abstract: PURPOSE:To protect a semiconductor switch and to control a motor even when a Zener diode is damaged. CONSTITUTION:A Zener diode ZD protecting a transistor (TR) Q1 is connected between a collector and an emitter of the TRQ1 controlling a motor M.

IPC: G06F1/28
Filed: 1995-02-21
Abstract: PURPOSE: To shorten a processing time and to prevent an operator from being confused due to misinformation by controlling a voltage detecting means based on the sort of a discriminated power supply. CONSTITUTION: When an operator turns on a power SW 20, a CPU 1 executes initial operation for a port or the like at first, and then turns the whole phases of a carrier motor 7 and an LF motor 8 to an unexcited state, completely turns off the drive of a head, limits the current consumption of the device only to logic, and fetches the value V1 of an A/D converter 12. Then the CPU 1 excites both the A and B phases of the motor 8 and fetches the value V2 of the A/D converter 12 again. The CPU 1 calculates V1-V2=ΔV, compares the calculated value ΔV with separation voltage Vref between a dropper type AC adaptor and a battery, and when ΔV>=Vref , the selection of the dropper type AC adaptor is judged and low battery check is not executed at all thereafter so as not to drive a low battery detection timer. In the case of ΔV<=Vref , low battery check is executed.

Filed: 1988-02-15
Abstract: PURPOSE:To easily respond to the increase of data capacity by using a register with capacity (N+1) bits for delay N bits from write to readout in case of concentrating data in which each M bits are distributed to a T time slot to an L time slot. CONSTITUTION:A storage means 10 is provided with the capacity in which 1 is added on the delay N bits from the write to the readout required for storage in the L time slot. The data in which each M bits are distributed in each slot whose one frame is the T time slot is written on the storage means 10 based on an effective bit signal to designate the number of effective bits of the data. Next, the readout from the storage means 10 is repeated for TXM/(N+1) times to concentrate the data in a continuous C time slot designated by an effective time slot signal 5'. In such a way, it is possible to manage the increase of the capacity of counter means 20 and 30 for write address and read address and the storage means 10 at small in capacity even when the data capacity is increased.

Title: Image forming device
Inventor: KAMIYA NASAKU
IPC: G03G15/16
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent an image irregularity by preventing a pitch wear which occurs on the surface of a photoreceptive drum at a pitch corresponding to the gear pitch of a transfer roller gear used for driving a transfer roller. SOLUTION: A transfer nip N is formed by making the transfer roller 4 abut on the photoreceptive drum 15. The photoreceptive drum 15 rotates and drives a photoreceptive drum gear 21, integrated with this, by means of a power source 20 via an idle gear 38 and drive gear 19. On the other hand, the transfer roller 4 rotates and drives the transfer roller gear 22 integrated with this by means of a different drive source via a drive gear 23. Because the photoreceptive drum 15 and transfer roller 4 are driven via power transmission paths which are different, the coincidence of the circumferential length of the periphery of the photoreceptive drum 15 and integral multiples of the gear pitch of the transfer roller gear 22 is prevented.  This prevents the surface of the photoreceptive drum 15 from being worn in the same position due to a vibration which is caused at each gear pitch of the transfer roller gear 4.

Abstract: PURPOSE:To prolong the life of a tool by applying ion plating of metal chemically active, relatively strong in reactivity, and having a little ionization potential energy on the surface of the tool, and then, of TiN on the initially plated surface. CONSTITUTION:Firstly, ion plating of one out of Al, V, Cr, Zr, and Nb is applied to the surface of a cutting tool to form a middle layer. In the next step, TiN is ionplated on the surface of the middle layer forming a surface layer.

Abstract: PURPOSE:To make accurate the position alignment of a grain boundary with a bridge part of a Josephson junction piece by forming marks on a substrate surface by etching, and by executing formation of an oxide superconducting thin film by using these marks as references. CONSTITUTION:Marks 21 and 22 to be references are formed by etching in the vicinities of both ends of a junction line of the surface of a bicrystal substrate 1 whereon a film is to be formed and in the vicinities of two corners on a diagonal line, at least, of the surface. Although the marks can be formed in the vicinities of four corners of the surface, of course, formation of the marks in the vicinities of two corners on the diagonal line of the surface suffices the need. An oxide superconducting thin film is formed on the bicrystal substrate 1 thus marked and is patterned with the marks 21 and 22 used as the references. Thereby a grain boundary 113 of the oxide superconducting thin film is disposed accurately in the central part of a bridge part 103.
