Title: Active by-pass circuit
Inventor: MIYOSHI KAZUNORI
IPC: H01L23/62
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To provide an active by-pass circuit, capable of reducing in-band impedance than that of a conventional active by-pass circuit. SOLUTION: This active by-pass circuit makes the AC component of noise arriving from a power line to by-pass to a negative power terminal P2 via a capacitor 200 and the base and emitter of a transistor 201. Since the by-pass circuit is driven by means of a current mirror 10 composed of two transistors 2 and 3, the impedance of the current mirror circuit 10 viewed from the base of the transistor 201 can be made larger than the conventional example. Therefore, the in-band impedance of the by-pass circuit can be reduced, because the AC component of the noise mostly flows to the by-pass circuit 103.

IPC: H02M7/48
Filed: 1990-05-28
Abstract: PURPOSE:To connect arbitrary number of unit inverters in parallel by detecting the output currents of unit inverters by current transformers, and comparing the currents of the inverters with an output current of a unit inverter to become a reference.

Title: Method for sending and receiving pulse train formed into consecutive phase signal by four-mode phase modulation
Inventor: TAKANO AKIRA
IPC: H04L27/18
Filed: 1990-05-28
Abstract: PURPOSE:To send and receive a consecutive signal in which the length of a modulation wave of each bit is variable by sending a 4-code form signal corresponding to each bit from a sender side, identifying the phase at a receiver side so as to demodulate the order of bits and the code. CONSTITUTION:Four code form signals are indicated in captions 1, 2, 3, 4 and a pulse bit string 5 of is sent and received sequentially from the left. In the case of sending the bit string 5, the leftmost bit is set as a 1st and an odd number order bit. Then a four-code form signal relating to the bit order and the bit level is sequentially sent, resulting in sending a consecutive signal 6. In the case of receiving the four code form signal, the phase of the consecutive signal 6 is sequentially decoded to demodulate the bit. Thus, lots of consecutive signals of variable length modulation waves are sent/received at a high speed.

Title: Composite gypsum mold
Inventor: AMAIKE TATSU
IPC: B28B1/26
Filed: 1987-05-30
Abstract: PURPOSE:To reduce the quantity of natural gypsum used by forming a slip casting surface of a gypsum mold of a gypsum layer and also forming an outer block of a calcium silicate material. CONSTITUTION:Gypsum slip is cast in a gypsum prototype mold of approximately 3mm or more, and then a calcium silicate sheet of approximately 0.3 gravity and approximately 15mm thickness is placed on its surface, and a mold of composite layer for use consisting of the slip casting surface of gypsum layer and a calcium silicate outer layer of calcium silicate material is prepared by removing the gypsum slip from the prototype mold after the same is fixed by pressure slightly and the gypsum is cured. In that case, a channel should preferably be provided on both surfaces in order to increase the bonding strength of the gypsum layer and the outer block of calcium silicate. As the calcium silicate material constituting the outer block is water absorbing, the water absorbed into the gypsum layer is also absorbed into the calcium silicate layer behind, and the mold dries in a shorter time than a solid gypsum mold, and can be used continuously.

Title: Base isolation structural system, and uplift-preventing device therefor
Inventor: SHIMODA IKUO
IPC: F16F15/04
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To simply install in a simple structure by a method wherein a vertical support function is provided between the upper and the lower structures and horizontal vibration transmitted from the lower structure is dampened and kinetic energy at the upper structure arising from horizontal displacement is absorbed. SOLUTION: Load of an upper structure G is transmitted to a lower structure B through a base isolation support device, and horizontal vibration of the upper structure G is prevented. For a strong wind working at the time of typhoon or the like as a side wind on the upper structure G whereon an uplift preventing device S is installed, the upper structure G is built in lightweight while lateral rigidity is made small for the base isolation support device. For uplift arising from horizontal vibration, resistance is made by vertical rigidity of the uplift preventing device S, and the horizontal vibration is absorbed by energy absorption of the base isolation support device. When a seismic motion occurs, shaking of the upper structure G caused by vibration at a foundation B is changed into vibration of long cycle by the base isolation support device.  Then vibration can be dampened by absorption of energy caused by plastic deformation of lead plugs of the base isolation support device.

Title: Pedometer
Inventor: TASAKA ISAO
IPC: G01H11/00
Filed: 1990-05-28
Abstract: PURPOSE:To improve accuracy by comparing pulse width with prescribed width set in advance, and discriminating whether or not the pulse width is effective. CONSTITUTION:The output of a sensor 1 consisting of piezoelectric ceramics, etc., is amplified by an amplifier part 2, and is converted to a pulse at a pulse conversion part 3. A pulse signal is inputted to an arithmetic control circuit 4 consisting of a microcomputer, and deadband time is attached on it, and the computation of the signal and the number of steps are performed, and a result is displayed on a display part 6. The pulse width of an input signal is compared with the prescribed width set in advance at the arithmetic control circuit 4. In other words, the minimum passing pulse width Tmin and the maximum passing pulse width Tmax are set in advance, and when the pulse width (t) of the input signal is within a range of Tmin<t<Tmax, the input signal is judged as effective. Also, when it is outside the range, it is judged as ineffective(input signals at both terminals at (a) in figure 1), which is not recognized as the number of steps, and it is ignored, then, the next pulse is awaited.

Title: Paper money discriminator
Inventor: HATTORI MIKI
IPC: G07D7/20
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To improve the discrimination rate of a paper money discriminator, loaded on an automatic vending machine, a money changer or the like. SOLUTION: This paper money discriminator 1 discriminates the authenticity of paper money 3 by pattern matching based on normalizing correlation. The master pattern P0 of true paper money 3 is stored in an EEP-ROM 15. The density data pattern P1 of paper money 3 to be discriminated is obtained through an optical sensor 6 and whether the pattern P1 coincides with the master pattern P0 or not is collated by pattern matching. Discrimination can be executed without reducing the discrimination rate due to the dispersion or the like of sensor sensitivity and a carrying mechanism differently from a conventional OR system. It is also unnecessary to sample the enormous data of paper money for preparing the master pattern P0. Therefore, an inexpensive paper money discriminator having a high discrimination rate can be realized.
