Title: Ultrasonic vibration converter converting vibration direction
Inventor: ANDO HIDEKAZU
IPC: B06B1/14
Filed: 1990-03-20
Abstract: PURPOSE:To convert a torsional vibration direction with high efficiency by positioning one set of longitudinal vibration bodies vibrating longitudinally in opposed relationship and holding a rotary body between the loop parts of both longitudinal vibration bodies. CONSTITUTION:A longitudinal ultrasonic vibrator 1 is fixed to the loop part L1 of a longitudinal vibration body 2 and flanges 3a, 3b are respectively provided at the positions of node parts N1, N2 while a longitudinal ultrasonic vibrator 4 is fixed to the loop part L3 of a longitudinal vibration body 5 and flanges 6a, 6b are respectively provided at the positions of the node parts N1, N2. A circular rod-shaped rotary body 7 is held between the loop parts L2 positioned at the central parts of the opposed vibration bodies 2, 5. Now, when a high frequency driving signal of the same phase is applied to the vibrators 1, 4, the vibration bodies 2, 5 are longitudinally vibrated in reverse opposed directions and these longitudinal vibrations are transmitted to the rotary body 7 by friction and, at a certain moment, the contact part of the vibrator 2 with the rotary body 7 is moved in a right direction and, at this time, the vibration body 5 moves to the left. When the magnitudes of these vibrations are same, the rotary body 7 is subjected to rotary motion and the conversion efficiency of the motion direction is 1.

IPC: G11B17/04
Filed: 1984-04-06
Abstract: PURPOSE:To reduce the manufacturing cost of a shutter opening-closing mechanism, by simply constituting the mechanism in such a way that a projected section for releasing a shutter locking mechanism is provided at the inside of a holder which guides a disk jacket and a wire spring for making the shutter driving operation at the inside of the holder nearer to the inserting port under a projectable condition. CONSTITUTION:When a magnetic disk jacket 103 is inserted into a space surrounded by the 1st holder 304 and its bent section 318 and bent sections 316 and 371 of the 2nd holder 307, a shutter 108 contacts with the bent section 312 of a wire spring 311, but a shutter locking mechanism cannot be released with the force of the wire spring 311 only. When the magnetic disk jacket 103 is further inserted, the pin section 315 of a guide shaft 309 releases the shutter locking mechanism and opens the shutter 108 thereafter. When the magnetic disk jacket 103 is further inserted until it stops, the bent section 312 of the wire spring 311 is engaged with a hole installed to the side of the shutter 108.

IPC: B23K9/10
Filed: 1983-04-18
Abstract: PURPOSE:To enable regulation of a welding output voltage from a DC power source for welding without using a control cable by converting the resistance change rate of a variable resistor for regulating the welding output voltage to a duty change rate of a digital signal and transmitting the same by a carrier on welding current cables. CONSTITUTION:The signal of a variable resistor 12 for regulating a welding output voltage is converted to a duty change rate by a converting circuit 28 and is applied as a modulating signal 28A together with the carrier signal 29A of a carrier generating circuit 29 to a modulating circuit 30, by which the signal is modulated to a carrier signal 30A. This signal 30A is superposed on welding cables 16, 17 via a transformer 31 and a capacitor 18. The signal 30A is drawn on the output voltage of a DC power source 14' by a capacitor 33 and a transformer 34 of the source 14' and a demodulating circuit 35 draws out only the modulating signal 35A. This signal is converted by a converting circuit 36 to a voltage signal of analog quantity, which is applied to a firing phase control circuit 6 of a thyristor and the output voltage of a welding machine is thus regulated.

Filed: 1989-03-20
Abstract: PURPOSE:To enable printing speed to be improved without causing an omission of necessary information by a method wherein a means which stops excitation by a continued second dot in the case of a dot pattern in which a same printing element is not continuously excited is established. CONSTITUTION:In the case where a printing data receiving from a host apparatus 1 is printed, a head control circuit 7 outputs a head control signal by a head driving signal of a main control part 2, reads a printing dot pattern from a pattern memory 4, transfers to a thermal head 6, and a thermal head electrification pulse together therewith applies thereto. A motor control circuit 8 receives a continuous dot presence signal to be outputted from an information storage part 5 by a motor driving command of the main control part 2, prepares a motor phase advancive timing pulse, and a paper feed motor 9 is rotated based on this signal. Then, in the case where a continuous dot exists, a data is altered so that electrification to a continued second dot may not be performed, an electrification cycle to the thermal head electrification pulse has the same cycle as traditional one, and paper carrying speed becomes doubled.

Title: Radio system, its reception terminal and its reception method
Inventor: YAGUCHI TAKESHI
IPC: H04W28/04
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To allow a mobile terminal to automatically receive a finally correct message by transmitting a re-transmission request signal to request re- transmisiion of data when the data have an error. SOLUTION: In the case of receiving a message from a base station side 106, the mobile terminal 101 receives the message signal and discriminates the presence of a data error in the received message signal by referencing data error checking data added to the message signal. The error checking as above is conducted in a minimum unit of the data. When the mobile terminal 101 detects an error in the received message signal, the mobile terminal 101 discriminates whether or not the data can be corrected, and applies error correction processing to the received data by using error correction data attached to the received data when the error is correctable.  On the other hand, the mobile terminal 101 discriminates the error to be incorrectable, the mobile terminal 101 extracts index data attached to the message, assembles a re-transmission request signal including the index data and transmits the re-transmission request signal of the message in order to request re-transmission of the message signal to an exchange 105.

Title: Connection circuit between semiconductor integrated circuits
Inventor: AOKI YASUSHI
IPC: H03K17/687
Filed: 1991-03-07
Abstract: PURPOSE:To attain high speed signal propagation and to reduce the power consumption by using a push-pull circuit composed of a P-channel MOS transistor(TR) for an output circuit, connecting the output to the input circuit of a bipolar semiconductor integrated circuit and to a power supply via a termination resistor. CONSTITUTION:The output circuit 10 of a CMOS semiconductor integrated circuit is constituted of a push-pull amplifier employing two P-channel MOS TRs MP1, MP2. When a logic level '1' is inputted to the input terminal ID1 of the output circuit 10, the TR MP1 is turned on and the output signal potential of the output circuit 10 is boosted to a power supply voltage VDD. Conversely when a logic level '0' is inputted to the input terminal ID1 of the output circuit 10, the output signal potential of the output circuit 10 reaches a potential VIL being an intermediate value between a threshold voltage and the VDD. The logical amplitude of the signal from the output circuit 10 is decreased, the signal is propagated at a high speed and since a so-called level conversion element is not employed, the power consumption is reduced.

Abstract: PURPOSE:To prevent an output stage transistor (TR) from being destroyed against grounding or short-circuit by connecting a base of the output stage TR to the 2nd and 3rd TRs and connecting a current source to a collector of the 3rd TR. CONSTITUTION:Let a current of a current source 9 be I9, DC amplification factors of TRs 8,3 be hFEQ8,hFEQ3 respectively and the DC amplification factor of a TR 5 be infinite, then the maximum collector current ICQ3 flowing through the TR 3 is expressed as ICQ3=I9 hFEQ8 hFEQ3. Entirely the same operation is applied to a current source ll at the lower part shown in figure. Thus, the maximum collector current flowing through the TRs 3,4 is set optionally by setting a cnrrent of the current sources 9,11 to a proper value. Thus, in selecting the current of the current sources 9,11 to a proper value, the destruction of the TRs 3,4 at grounding or short-circuit is prevented.
