Title: Picture signal coder and decoder
Inventor: KURAHASHI SOJI
IPC: H04N19/625
Filed: 1993-05-07
Abstract: PURPOSE:To allow the coder/decoder to cope with controlling a code quantity by preparing a code book with respect to scaling factors and a quantization matrix set as a reference in advance. CONSTITUTION:A data block generated by a block processing circuit 2 is given to an orthogonal transformation device 3, in which 2-dimension orthogonal transformation such as discrete cosine transformation is applied to each block to obtain a transformation coefficient. A multiplier 6 multiplies each quantization step and each scaling factor fed from a quantization table 5 and a quantizer 7 quantizes the transformation coefficient based on the obtained coefficient. A variable length coder A8 generates a variable length code from an output of the quantizer T. The scaling factor and the variable length code are sent to a transmission line 10 via a bit stream mixer 9. A variable length decoder 12 decodes a quantization coefficient from the variable length code separated by a bit stream separator 11 and a multiplier 13 multiplies the quantization coefficient and the scaling factor, a table retrieval device A retrieves a relating code book to obtain a code vector.

Title: Semiconductor device
Inventor: IIJIMA TETSUO
IPC: H01L29/78
Filed: 1994-05-20
Abstract: PURPOSE:To increase an input protection function by improving clamping effect without increasing the occupation area of an input protection diode formed near a bonding pad. CONSTITUTION:A diode for forming an input protection circuit of a power MOS transistor is formed at a polysilicon layer 3 below a gate electrode 5A. The polysilicon layer 3 is formed on the substrate 1 via a silicon oxide film 2. A number of mesh-shaped diode parts 20,... are formed on the entire surface of the polysilicon layer 3 and are connected in parallel between the gate electrode 5A and a source electrode 5B, thus constituting a diode and hence increasing the area of the pn junction of a diode formed within a certain area and reducing the parasitic capacitance. As a result, when a large surge current is applied to the gate, a voltage appearing across the diode becomes small, a voltage (breakdown voltage) applied to a gate oxide film is kept low, and the input protection resolution of the diode can be improved.

Title: Piezoelectric transformer type power converter
Inventor: ABE TORU
IPC: H02M7/48
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To suppress or remove the DC component of an excitation voltage by providing a piezoelectric transformer connected in parallel with a switching means connected to a DC input power source connected with an inductor, a serial circuit of capacitors, and a switch driving and oscillating means. SOLUTION: The input voltage V1 of a piezoelectric transformer type power converter is 10 V and a serial capacitor 10 has an electrostatic capacitance CR=10 μF (equivalent parallel resistance RPC of 1 GΩ). A piezoelectric transformer 50 has an input electrostatic capacitance CT1 of 110 nF (equivalent parallel resistance RPT of 5 GΩ), and an additional parallel resistor 100 has a resistance value RH of 2 MΩ. The driving frequency of the converter is 58-63 kHz. A half-sine-wave voltage B21 has a waveform containing a DC component and the excitation voltage V22 of the transformer 50 becomes such a waveform that deflects to both the positive and negative sides and the DC component contained in the voltage V22 is almost zero. The half-sine-wave voltage V21 is divided into the excitation voltage V22.  In this driving frequency domain, the voltage V21 is divided by the electrostatic capacitance when the voltage V21 is derided as an AC component and the DC component impressed upon the input of the transformer 50 becomes almost zero (about 20 mV), because the impedance of the electrostatic capacitance is sufficiently smaller than the equivalent parallel resistance and additional parallel resistance value.

Abstract: PURPOSE:To simplify operation when recording is performed at random by leaving blanks, by setting a pause state when voice signals are not inputted for a prescribed time under a recording mode and releasing the pause state on receiving an address signal. CONSTITUTION:When recording signal current maintains a value that forms no voice recording part on a tape for a prescribed time under a recording mode, a pause signal is generated through a pause signal generating circuit 11. When one of address keys 6A-6C is depressed, an address signal corresponding to each key is outputted and recorded on a tape 4. At the same time, the address signal is supplied to a solenoid 16. If this solenoid is in a position to make a pause state, the pause state is released, and voices from a microphone are recorded on the tape 4 consecutively to the address signal recording part. By this way, operation at the time of recording at randam by leaving blanks can be made  simple.
