Title: Phase shift keying demodulator and demodulation method using period width window technique
Inventor: JOHNSON ROBERT E
IPC: H04L27/227
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a phase shift keying(PSK) modulator and a modulation method which use a period width window technique. SOLUTION: This demodulator 10 demodulates a PSK communication signal by using a synchronizer 12, a period window detector 20 and a logical device 22. The synchronizer 12 supplies a transition signal for indicating a reference edge of a communication synchronizer. A period window connected to the synchronizer 12 establishes a time period on the basis of a period of the transition signal. The logical device 22 which has input connected to output of the period window detector 20 generates a logical output signal. This demodulator 10 is equipped with a carrier wave boundary detector 34 for turning a message into a frame and minimizing detection of a noise, thus it becomes possible to measure a signal intensity oven a wide dynamic range.

Title: Vehicle propeller shaft
Inventor: FUJITA YASUSHI
IPC: F16C3/02
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce vibration produced by a propeller shaft by preventing occurrence of self-exciting whirling vibration caused by internal friction of a universal joint. SOLUTION: A propeller shaft assembly 1 is composed of a first shaft P1 having an axial length L1 , a second shaft P2 having an axial length L2 which is smaller than the first axial length L1 , and a universal joint C3 coupling the first and second shafts together. When the first and second shafts are arranged so as to define a crossing angle thererbetween, depicting a leftward convex shape with an apex at the position of the universal joint. Accordingly, a folding angle at the universal joint C3 , in particular, an folding angle θ3 at the universal joint C3 at a third uniform speed can be increased with the use of a secondary moment which is produced by a drive torque T when the input force to the propeller shaft 1 becomes larger, and accordingly, self-exciting whirling vibration caused by internal friction of the universal joint is prevented. Thereby it is possible to reduce vibration and noise produced by the propeller shaft 1, in particular, vibration and noise in a running condition in which the input torque becomes larger.

IPC: H05K3/34
Filed: 1987-12-07
Abstract: PURPOSE: To eliminate the need for washing after soldering and to entirely eliminate the electrical shorting by solder grains by previously plating conductor patterns and external outgoing leads respectively with solder. CONSTITUTION: The external outgoing leads 2 of the flat display panel 1 and the conductor patterns 4 of a printed circuit board 5 corresponding to the outgoing leads 2 are respectively immersed into a solder vessel and are previously coated with the solder.

Title: Banding machine
Inventor: FINZO FLAVIO
IPC: B65B13/22
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To improve efficiency in an energy amount required for binding operation with band tension by holding a band for binding an article between a locker of a tension banding driving part and a tension wheel and by placing it on the tension wheel at an entire angle of winding. SOLUTION: A tension wheel 30 can be in contact with two contact rollers attached to a locker 37 by rotational motion around a rotary spindle. A distance between the two contact rollers is sized so that an entire angle of winding αof a band on the tension wheel 30 is appropriate. The distance between the two contact rollers should be approximately 70% of a radius of the tension wheel 30, wherein resultant force of a pressure applied by the wheel 30 to the locker 37 should not intersect with a locker axial line. As a result, when the wheel 30 to the locker 37 applies the pressure, torque always exists around the locker axial line, whereby the locker 37 can be well lined with the tension wheel 30.

Abstract: PURPOSE:To enable remote controlling without affecting uniformity of magnetic field by turning around a shaft connected to a variable condenser, by a flexible wire extending from a probe outside. CONSTITUTION:The object frequency is designated by a preset unit 10 and an oscillator generates an RF frequency corresponding thereto. The RF frequency is amplified by an amplifier 12 and charged to a tunable probe 2 through a power detector 13. The reflection wave therefrom is detected 13 and then sent to an automatic tuning control unit 5. Also, the unit 5 controls a stepping motor to regulate a variable condenser so that deviation of the probe 2 might be regulated through flexible wires 6a and 6b, and shafts 4a and 4b. In this way, a driving mechanism such as a motor can be arranged at a position enough far from affecting uniformity of magnetic field unfavorably. Also, since the flexible wires are brought out along a magnetic axis Z, remote controlling can be conducted without any degradation of resolution thereof.

Title: Data protecting device for non-volatile memory
Inventor: OSAWA HIROSHI
IPC: G06F21/79
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous writing of program contents accompanied by the runaway of program processing. SOLUTION: At the time of initializing one chip microcomputer, the boosting operation of a boosting circuit 17 is executed only when an RS type flip flop 21 is reset. Thus, when initialization is insufficient, there is high possibility that the value of an address register 3 is not 0 address while the RS type flip flop 21 is set. Hence, the runaway of the program processing of the microcomputer is generated, and yet any erroneous writing in a flash memory 1 can be surely prevented.

Abstract: PURPOSE:To sharply reduce information quantity of a picture data by sending only a block line subjected to change based on a block number and correcting the revised part based on an original coded picture data and a coded picture data to be returned. CONSTITUTION:A picture comparison section 11 compares a picture data already received and stored in a reception data storage section 10 with a picture data revised by a receiver side for each block line and extracts block lines in which the result indicates difference and adds a block line number corresponding to the revised block line and sends the result to a sender via a communication interface section 7. The sender side references the coded data stored in a transmission data storage section 4 with the coded data sent from an opposite equipment based on the block line number, replaces the coded data stored in the transmission data storage section 4 with the data for each sent block line and a coding decoding section 3 decodes the result thereby allowing the sender side to reproduce the picture equal to the corrected picture at the receiver side.

Filed: 1992-11-19
Abstract: PURPOSE:To allow highly accurate detection of sinusoidal distortion with no thermal effect from heating furnace by measuring displacement of a probe in thrust direction at a part held between two leaf springs through the use of an L-shaped core fixing metal. CONSTITUTION:An L-shaped core fixing metal 7 is secured, at one end thereof, to a part of a probe 4 being secured resiliently through a leaf spring 5 to a housing 14 and a rod 7a penetrates through a hole made through a leaf spring 5 on B side, without contacting therewith, and arranged in parallel therewith.

This constitution allows highly accurate detection of distortion of a sample through the transformer 9 even for the stress in radial direction due to micro axial shift at the time of fixing the probe when a sinusoidal stress is applied to the probe 4 in thrust direction. Furthermore, degree of freedom is increased in the fixing position of the core 8 and the transformer 9 susceptible to environmental temperature can be set at a position remote from a heating furnace 15.
