Title: Band rejection type filter using idt type surface acoustic wave resonator
Inventor: ISOBE ATSUSHI
IPC: H03H9/145
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a band rejection type filter with high attenuation at a lock band. SOLUTION: Plural IDT surface acoustic wave resonators, each using a θYX-LT piezoelectric substrate 5 and Al electrodes 1A, 1B are connected in series and number of pairs of the resonators, the electrode period, the film thickness and a value θ are selected to be desired values. Thus, the propagation loss of a surface acoustic wave in the vicinity of an anti-resonance frequency o the resonator is negligibly small. As a result, the attenuation is improved by 4 dB or more compared to that of a conventional band rejection filter employing a 36 XY-LT piezoelectric substrate.

Title: Communication controller
Inventor: KATO EIJI
IPC: G06F13/00
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To reserve a communication line by deciding a communication line to be open based on the notice received in advance as to each communication speed and the priority of each communication line and a performance reference value of its own equipment. SOLUTION: When an information processing unit 1 gives an open request command to a processing section 24 of a communication controller 2, the processing section 24 checks the communication speed the communication rate from a received open request command and compares the rate with a performance margin. When the performance margin is not reserved, the processing section 24 checks the communication line during open with lower priority than the priority of the line number whose request is open, and the margin when the communication line with low priority is blocked is checked. The margin is compared with the performance margin to decide an open enable line thereby reserving the communication line.

Title: Amplifier circuit and semiconductor integrated circuit using it
Inventor: ARAKAWA FUMIHIKO
IPC: H03F1/02
Filed: 1993-12-15
Abstract: PURPOSE:To increase a maximum linear input current without reduction of a trans impedance by adding a resistor newly between a transistor(TR) provided to an output terminal of a 2nd TR amplifier circuit amplifying an output of a 1st TR amplifier circuit and feeding back the amplified signal to an input of the TR and the output terminal. CONSTITUTION:A resistor Rf1 is connected to a preamplifier 50 as a feedback resistor and a resistor Rf2 is newly connected between an emitter output terminal of a TR Q2 and a resistor Re. A collector of a TR Q1 is connected to a base of the TR Q2 and to a power supply VCC via a resistor R2. An emitter of the TR Q1 connects to ground. A collector of the TR Q2 is connected to the power supply VCC, the emitter is connected to an output terminal OUT and to ground via the resistor Rr. and R2. A connecting point between the resistors Rf2 and Re is connected to a base of the TR Q1 via the resistor Rf1. An input current iin of the preamplifier 50 is expressed as iin=VBE/(Rf1+Re), where VBE is a base-emitter voltage of the TR Q1. Thus, the maximum input current is larger when the sum of the resistance of the resistors Rf1, Re is smaller and independent of the Rf2. On the other hand, the reduction in the trans impedance is suppressed by increasing the resistance of the resistor Rf2.

Title: Communication terminal equipment
Inventor: NAMIKAWA HIROSHI
IPC: G06F13/00
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a communication terminal equipment by which data DMA transfer between a RAM and a MODEM modulator-demodulator is realized at a low cost. SOLUTION: A MODEM 9 sends a transmission request signal or a reception request signal as an interrupt signal. When the transmission request signal or the reception request signal is given to a DMA(direct memory access) controller 1a, a CPU 1 releases a bus and the DMA controller 1a acts as a bus master of the bus 12. A DMA address designation section 8 uses an address changeover section 8b to select a transmission reception register address generated by an address generating section 8a to send the address to the MODEM 9 depending on a command from the DMA controller 1a based on the request of the MO DEM 9. Thus, in the case of transmission, DMA transfer of transmission reception data is conducted from a RAM 7 to a transmission register 9a of the MO DEM 9 in the case of transmission and from a reception register 9b of the MODEM 9 to the RAM 7 via the bus 12 in the case of reception.

Filed: 1988-12-13
Abstract: PURPOSE:To prevent the generation of the short-circuit between wires and to make it possible to connect reliably the wires with leads by a method wherein the widths of regions, to which the wires are connected, of the leads of a lead frame are made wider than those of the other regions of the leads and at the same time, the adjacent leads are formed in such a way as to have a step difference. CONSTITUTION:A lead 2b, for example, of adjacent leads 2a and 2b is bent downward in such a way that a step difference is provided on the surfaces of the leads 2a and 2b. Moreover, regions, to which bonding wires 6 are respectively connected, of the leads 2a and 2b are formed wider than the widths of the other regions of the leads. At this time, as the interval between the adjacent leads 2a and 2b becomes wider, it is eliminated that the fellow wires 6 come into contact to each other. Thereby, with the wires 6 connected reliably with the leads 2a and 2b, the fellow wires are never short-circuited.
