Title: Communication equipment having reference signal frequency calibration function
Inventor: SUDO SHIGEYUKI
IPC: H03J7/02
Filed: 1991-12-12
Abstract: PURPOSE:To provide the communication equipment whose reference frequency oscillator tracks a base station with high accuracy. CONSTITUTION:A reception signal is converted into a 1st intermediate frequency signal at a 1st frequency converter 4, then converted into a 2nd intermediate frequency signal at a 2nd frequency converter 6, the signal is detected by a quasi-synchronization detector 8 and the result enters a phase compensation section 10, in which phase compensation is implemented based on the result of estimate of a frequency error stored therein in a 2nd local oscillator 19. A frequency estimate device 11 outputs a frequency error signal estimated from an extracted phase rotation component from an output of the phase compensation section 10. The device 11 outputs a signal, it is inputted to a frequency correction section 14, which outputs an oscillated frequency adjustment control signal controlling a reference oscillator 15 to minimize a frequency error signal from the frequency estimate device and the frequency correction section 14 corrects the reference oscillator 15. Since the transmission frequency is set based on the reference oscillator 15 at the transmission, the oscillator tracks the base station by the oscillation frequency control of the frequency correction section.

Title: Charger
Inventor: YASUTOMI HIROSHI
IPC: G03G15/02
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To effectively suppress charge unevenness and to increase the degree of freedom of the resistivity of a resistance layer by providing a layer made of a material having a nonlinear current-voltage characteristic, on a surface facing a charged surface. SOLUTION: The layer 2a made of the material having the nonlinear current- voltage characteristic (abbreviated as a varistor layer in the following) is provided on the surface facing a photoreceptor 1a of a charge plate 2. In the charge plate 2, the resistor layer 2b is formed on a conductor 2c and the varistor layer 2a is formed on the resistor layer 2b as well. The varistor layer 2a dose not discharge electricity in a place where the distance between the charge plate 2 and the photoreceptor 1a is long, because the resistivity of the varistor layer 2a is high, but discharges the electricity in a place where the distance is short, because the resistivity of the varistor layer 2a is low.  Thus, in the charge plate 2, the occurrence of the charge unevenness of the photoreceptor 1a is prevented and further, the setting of the resistivity of the resistor layer 2b is easier than that of a conventional contact charger.

Abstract: PURPOSE:To enable use of a low-speed low-volume high speed solenoid valve by providing a fixed throttle between the pilot port of a pilot spool and a tank, while providing a high speed solenoid valve between the pilot port and a pilot pump, and performing pressure control by the fixed throttle and the high speed solenoid valve in cooperation. CONSTITUTION:The rate of opening-closing time of a high speed solenoid valve 32 is set at a required value in a specified control range by a PWM drive circuit 33. Then, pressure in a pilot chamber 16 becomes a value to be fixed by a fixed throttle 34 and according to this set value.

Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To maintain clear permeation from one side to the other side of a panel excepting a part covered by a design by arranging a base part, in which a pattern is formed on a light permeable material by means of a monochromatic layer, and a design part which is formed into a pattern shape so as to cover a part, of the base part by means of a printed layer in different color from the base part. SOLUTION: In a restriction pattern 26 in a dark ink arranged on one side of a sheet 10, light color (light reflecting) ink 25 and another color ink 28 are overlapped with each other, and relative arrangement of the ink 25 and the ink 28 generates a design carrying certain transmitting information.
