Title: Recording and reproducing device of optical data
Inventor: TAKASUGI KAZUO
IPC: G11B20/18
Filed: 1983-11-18
Abstract: PURPOSE:To execute suitably setting of an error correcting capacity and a criterion of re-write, so that the validity as a system can be raised, by selecting an error correcting function of an error correcting code so as to be larger than a degree of an error caused in the decision of re-write. CONSTITUTION:A modulation circuit 3 generates a write signal to a disk 4. A reproducing signal read out of the disk 4 is inputted to a data splitting circuit 6 through a demodulation circuit 5, and a data is split to a correcting unit from the reproducing signal, corrected by an error processing part 7, and fetched as a data DO. In this case, at the time of write, the data is written, also the written data is read out, the written data and the read-out data are compared by the part of a deciding circuit 8, and if an excessive error exists, re-write is executed by outputting a re-write control signal CS. That is to say, an error correcting capacity which a code has is selected larger than a degree of an error which is decided to be re-write, and when a degree of an error detected at the time of a write check does not reach the limit of the correcting capacity but is smaller than it, the error is decided to re-write.

Title: Cmos logic circuit
Inventor: IWAMURA MASAHIRO
IPC: H03K19/21
Filed: 1984-10-17
Abstract: PURPOSE:To eliminate an offset of an output level by providing a complementary switch comprising parallel connection of a PMOS and an NMOS between one of inputs and an output so as to drive each gate with a positive or an inverted signal of the other input. CONSTITUTION:One electrode each of the PMOS15 and the NMOS16 is connected in common to an input B. Other electrode each of the PMOS15 and the NMOS16 is connected in common to an output C. The gate of the PMOS15 is connected to the input A and the gate of the NMOS16 is connected to a point P corresponding to an inverted level of the input A. When the level of both the inputs A and B is logical '0', an NMOS54 is turned off, and an PMOS53 and the PMOS15 are turned on. An output C is decreased to DELTAV1 by the discharge of the PMOS53 and the PMOS15. On the other hand, since the level of the point P is logical '1', the NMOS16 is turned on. As a result, the charge of the output C is discharged to '0' completely and the level is logical '0'.

On the other hand, if a second character is included in the character combination determined by the random number generating means 4, the character combination is again determined by the other random number on the basis of a third inside reel strip. Thus, a noble active game for stimulating player's will of playing the game can be developed.

Title: Optical amplifier
Inventor: YAMAZAKI HIROYUKI
IPC: H01S3/10
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To make roughly constant the gain of an optical amplifier, even if the total power of an input signal changes. SOLUTION: A transmitter 10 outputs a multiplexed light signal. The multiplexed light signal is transmitted through an optical fiber transmission path 20. An optical tap coupler 31 branches the transmitted multiplexed light signal. A light-receiving monitor element 32 converts this signal into a light electrical signal. A control circuit 33 outputs a voltage, which is proportioned to the difference between voltages which are inputted from input terminals 133a and 133b. A light source element 34 emits light by a control voltage from the circuit 33. A WDM coupler 35 combines lights of input terminals 135a and 135b. An light amplifying fiber 36 amplifies the input signal light by excitation light from an excitation light source element 38. An optical filter 37 removes wavelength components other than those of the input signal light and the excitation light. A WDM coupler 39 outputs amplified light outputted from the filter 37. The amplified light is transmitted through an optical fiber transmission path 40 and is received by an optical receiver 50.

Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical multiplexer/demultiplexer which has the function of D-WDM and the function of WDM by using one optical component by forming a reflection grating at a specific position of a channel waveguide array for connection. SOLUTION: Light of the 1.55μm band which is made incident on an input waveguide 41 spreads laterally because of diffraction effect when entering an input-side slab waveguide 43a, and then enters the respective waveguides of the waveguide array 45. Refraction gratings 46 of the 1.55μm band are formed almost in the center of the waveguide array 45 and the position of each reflection grating 46 is shifted by certain length from an input-side slave waveguide 43a. Consequently, the lights which are made incident on the respective waveguides are different in reflection position and the tilts of equal-phase surfaces are different by wavelengths of the 1.55μm band right before the input- side slab waveguide 43a.  Namely, the light of the 1.55μm band is projected from an output waveguide 42 and branched, and light of the 1.3μm is projected from an output waveguide 44 without being affected by the reflection gratings 45 of the 1.55μm band.

Title: Facsimile equipment
Inventor: KUMANO TOSHIYA
IPC: H04N1/00
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To properly use facsimile communication or usual telephone communication by discriminating a pattern of a call signal sent from an external line and automatically selecting the external line to a facsimile transmission reception section when a prescribed call signal is received so as to effectively utilize a ring service depending on the type of communication. SOLUTION: In the case of a call signal with different ringing tones depending on a communication type, facsimile equipment A discriminates a call signal pattern as to whether it is facsimile communication or usual telephone communication. As a result, a CPU 1 selects the facsimile communication mode in the case that the discrimination indicates a facsimile pattern, that is, the CPU 1 turns a CML relay RY to contacts a, b, and a signal from an external line reaches a MODEM 2. When the discrimination does not indicate the facsimile pattern, the CPU 1 turns the CML relay RY to the contacts c, d, and a signal from the external line reaches an ancillary telephone set, and a bell of the ancillary telephone set rings. And when the handset of the telephone set is hooked off, the signal reaches the ancillary telephone set.  The different ringing tones depending on a communication type are utilized, so that the pattern is discriminated before charge imposition and the signal is reached after changeover.
