Abstract: PURPOSE: To maintain signal integrity and reliability and to minimize the signal processing load by storing a quadrature base band component and correcting a clock phase and a carrier phase of a base band sample based on an estimated phase error/carrier phase error respectively. CONSTITUTION: A reception signal from an antenna 32 is converted into an intermediate frequency (IF) signal by a mixer 36 via a transmission reception changeover device 33, a BPF 34, and a low noise amplifier 35, the IF signal is filtered by an IF processing circuit 37, mixed with a base band frequency signal at a quadrature mixer 38, and I and Q phase signals of the two quadrature base band components are outputted to a base band signal processing circuit 31. The signals I, Q are filtered in the circuit 31 digitally after low-pass filter processing. The result is stored in delay buffers 51, 54 at a prescribed signal level and the clock phase and the carrier phase are corrected based on the phase/carrier phase error estimated by the estimate devices 52, 55. Output signals I, Q are transmitted via a modulator 39, a power amplifier 42, a changeover device 33 and the antenna 32.

Abstract: PURPOSE:To generate a clock, which can send a transmission signal of less jitter to a home device and has less jitter, in an intra-office terminating equipment by providing a master clock oscillator, a frequency division ratio designating circuit, a variable frequency dividing circuit, or the like. CONSTITUTION:The master clock from a master clock oscillator 1 has the frequency normally divided by N in a variable frequency dividing circuit 2 to generate an output clock, and this output clock is outputted to a fixed frequency dividing circuit 3. The circuit 3 outputs the inputted clock to a phase comparing circuit 4 after frequency division, and the circuit 4 compares its phase with the phase of the reference clock extracted from a network. The frequency division ratio of the circuit 2 is changed by a frequency division ratio designating circuit 5 in accordance with the comparison result to synchronize the phase. In this case, a frequency fM of the master clock is set to satisfy fM=f0XN+  or fM =f0XN-  where f0 is the nominal frequency of the output clock. Thus, the frequency in occurrence of jitter is reduced to improve the circuit characteristic.

Title: Discriminating device for reset signal of microcomputer controller
Inventor: HAYATA YOSHIKI
IPC: G06F1/00
Filed: 1985-09-18
Abstract: PURPOSE:To discriminating a reset state in the runaway mode of a microcomputer from a reset state in the drop mode of voltage, by providing a timer circuit consisting of a resistance, a capacitor, a diode, etc. and deciding the rest state according to the output voltage of the timer circuit. CONSTITUTION:When a microcomputer 1 is in a runaway state, a runaway detecting circuit 6 outputs a reset signal. In such a case, a power supply 3 has no drop of voltage and the output of a timer circuit consisting of a capacitor 5, a resistance 4 and a diode 13 is kept at H. While the charging electric charge of the capacitor 5 is discharged quickly via the diode 13 when a reset signal is delivered from a power supply voltage detecting circuit 7. Then the output of the timer circuit goes to L. As a result, a reset state due to the runaway of a microcomputer can be discriminated from a reset state due to the drop of the power supply voltage. Then the power supply 3 is switched to a back-up power supply 2, etc. by an appropriate program.

Title: Laminate for piezoelectric device, its manufacture, and manufacture of the piezoelectric device
Inventor: SUZUKI YOSHIHIKO
IPC: H01L41/22
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To improve the bonding strength between a raw material for piezoelectric element and a semiconductor substrate by providing a metallic material layer made of a metallic material, having a low melting point between the material and the substrate. SOLUTION: A raw material 2 for piezoelectric element is obtained by forming a metallic thin film 21, having a high melting point on the joint surface side of a raw material main body 20 by the sputtering method. At the same time, a semiconductor substrate 3 is obtained by forming a high-melting point metal thin film 31 on an oxide film 33 forming surface of a substrate main body 30 by the sputtering method. Then, metal thin films 40 and 40 made of a metallic material having a low melting point(<=820 deg.C) are respectively formed on the material 2 and the substrate 3, so as to evenly cover the thin films 21 and 31.  Thereafter, a metallic material layer 4 having a low melting point is formed, by putting the material 2 on the substrate 3 so that the thin films 21 and 31 adhere closely to each other and impressing a high frequency upon the thin films 21 and 31, while the thin films 21 and 32 are press- contacted with each other, and then, cooled. Since the metallic material layer 4 works as an adhesive which bends the material 2 to the substrate 3, the material 2 and the substrate 3 can be laminated firmly upon another and formed integrally. Therefore, the bonding strength between the material 2 and the substrate 3 can be improved.

Title: Air conditioner for automobile
Inventor: KONDO MASAHIRO
IPC: B60H1/32
Filed: 1986-08-29
Abstract: PURPOSE:To make it possible to heighten the operation rate of a compressor so as to increase the cooling capacity of an air conditioner, by switching a set-temperature for intermittent operation of the compressor into a low value, when an inside air mode is set. CONSTITUTION:When an inside air mode is selected, an inside air mode switch 59 is turned on. As a result, a base current runs in a transistor 52 in a control circuit 46, thereby turning the transistor 52 on. Thus, a resistance 48 is short-circuited. Then, the voltage at point A is raised from the first set voltage to the second that is higher than the first set voltage. As a result, the voltage at point A stays higher than that at point B until the blow-off temperature of an evaporator 15, which is detected by a temperature sensor 57, becomes lower than the second set temperature that is lower than the first. Thus, since the output from a comparator 54 remains '1', the operation of a compressor 31 continues. After this, if the blow-off temperature is lowered down to the second set temperature, the output from the comparator 53 turns '0', and the operation of the compressor 31 is stopped. Since the operation of the compressor 31 is performed intermittently like this between the first and second set temperatures under the inside air mode, the operation rate can be enhanced, while the refrigerating capacity can be increased.

Filed: 1994-08-30
Abstract: PURPOSE: To prevent generation of error signal by subjecting the inner face of a holding member to antireflection processing. CONSTITUTION: A luminous flux generated from a light emitting element 2 impinges on the light receiving face of a position detecting device 1 through primary reflection on the inner face of a holding member 5, or reaches a device 2 through plural reflection on the member 5 and the arm of a moving member 3, or an external light intruded through an opening of the member 5 reaches the device 1 directly or through reflection on the inner wall of the member 5, the arm of the member 3, etc. In this regard, a divider does not output a correct value proportional to the shift of a slit 3a but outputs the weighted mean of a spot produced through the slit 3a and a spot of received light produced through reflection on the inner face or extrusion of external light thus generating an error signal.  When shade lines A are provided on the inner wall of the member 5 and at the arm part of the member 3, the light reflected on the inner face, the externally intruded light, and the luminous flux reaching the device 1 through reflection are scattered and generation of error signal is prevented.
