Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To obtain a wavelength equalizer capable of realizing level equalization and level monitor of a wavelength multiplexed signal by using one optical multiplexer/demultiplexer. SOLUTION: Output level monitor is enabled, in addition to demultiplexing and multiplexing for wavelength equalization by one optical multiplexer/ demultiplexer 18 by inserting an optical branching device 19 into demultiplexed output of a reflection type wavelength equalizer formed by combining the optical multiplexer/demultiplexer 18, an optical reflector 17 and an optical circulator 15. Thus, a deviation of characteristics by using plural optical multiplexer/ demultiplexers is eliminated. In addition, since optical components except the optical multiplexer/demultiplexer 18 are realized by a simple structure, they are made into an array on the same substrate and the structure becomes one suitable for integration.

Title: Power-on reset circuit
Inventor: ADACHI TAKATOSHI
IPC: H03K17/22
Filed: 1989-10-06
Abstract: PURPOSE:To improve the control accuracy of a power-on reset circuit by controlling qualitatively a voltage range subjected to power-on reset. CONSTITUTION:A 3rd transistor(TR) is provided in parallel with a 1st TR of an inverter comprising 1st, 2nd TRs and a bias potential divided by an impedance element is fed to the gate of the 3rd TR. Thus, even in the presence of the manufacture process, since the bias potential depends on the voltage division ratio of an impedance element, the dispersion is not almost affected. Concretely, assuming (1)-(4) as the potential of each node, then, when the level (2) divided by resistors R1, R2 is smaller than a threshold level of a TR 4, the Tr 4 is turned off and an output of a reset voltage control circuit 13 is in the reset state. When the level is higher than the threshold level, the TR 4 is turned on and a through-current flows between the TRs 4, 5 and the resistor R3, the output of the circuit 13 goes to a high level to wave the reset state.

Title: Active filter
Inventor: FUJIMOTO RYUICHI
IPC: H03H11/04
Filed: 1992-10-01
Abstract: PURPOSE:To suppress the increase of the current consumption and to extend the input signal range by giving a difference between linear input ranges of first and second variable gain circuits. CONSTITUTION:This active filter fundamentally consists of an input part 1 where the linear input range is extended, a terminal resistance part 2 on the output side, a filter part 3, an input terminal, and an output terminal 5. Even when an input signal having a large amplitude is inputted to the filter, the input part 1 accepts the input signal without distortion because the linear input range is extended in the input part whose input signal range is extended. Since the input signal having an amplitude smaller than that of the input signal inputted to the input part 1 is inputted to the filter part 3, the filter part 3 can consist of a constituting element whose input signal range is narrower than that of the input part 1. Consequently, the increase of the current consumption is suppressed without distortion even for the input signal having the large amplitude.

Title: Aqueous emulsion adhesive
Inventor: IWASAKI KINJI
IPC: C09J201/00
Filed: 1990-10-01
Abstract: PURPOSE:To obtain the title adhesive which is excellent in initial adhesiveness and enables high-speed joining of adherends by forming an emulsion in such a manner that the mean particle diameter is in a specified range and the particles having a diameter in a specified range account for a percentage in a specified range. CONSTITUTION:The title adhesive which has a mean particle diameter of 1.5-3.5mum and in which the particles of 2-3mum in diameter account for 15-40vol.% of the total particles. Unlike organic solvent type adhesives, conventional aqueous emulsion adhesives based on, e.g. polyvinyl acetate and acrylics are excellent in handleability and have an advantage in the freeness of environmental pollution; however, they cause difficulty in high-speed joining from an aspect of the adhesive strength. Although it is an aqueous emulsion, the title adhesive is excellent in initial adhesiveness and enables high-speed joining of adherends. As the monomer for forming the polymer particles of the emulsion, those in common use, such as a vinyl monomer, styrene monomer, and (meth)acrylate, can be used.

Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To reduce a control load comparatively by storing each digital signal as to an analog signal of the other group latched in a register circuit just before a selection means returns to a selection output operation of an analog signal of one group. SOLUTION: Whether or not A/D conversion of each detected operation parameter from an input circuit 2 is conducted is discriminated by a CPU 8. Since a digital value of an input operation parameter detection signal of analog input ANI8-ANI15 is stored in a register circuit 5, the end of A/D conversion is delivered from a changeover controller 7. Then the CPU 8 reads each latched value of latch area ADCR0-ADCR7 and stores it to a 2nd data storage area of a RAM 9. Since DM8-DM15T by 8 channels corresponding to the storage area are provided to the RAM 9, each of latched values ADCR0-ADCR7 is sequentially transferred to the RAM 9 and written in 2nd data storage areas DM8-DM15.
