Title: Centrifugal radiation propeller
Inventor: ICHIKAWA HIROSHI
IPC: B63H11/08
Filed: 1981-07-10
Abstract: PURPOSE:To secure propulsion force in the turning radius direction with centrifugal force acting on fluid transformed into the propulsion force, by installing the required number of radiant tubes in a rotating circular cylinder and overlapping a part of these tubes. CONSTITUTION:Radiant tubes 2 are set in the required number of holes provided around the outer boundary of a rotating circular cylinder 6 and also a rotor shaft 1 is fixed at the center of a bottom 3 of the cylinder 6. At a supporting structure 5, there is provided with a reflecting container 4 comprising the rotating circular cylinder plus a part of the radiant tubes 2. Therefore, with rotation of the cylinder 6, fluid is emitted out of the radiant tubes but the fluid radiated into the reflecting container 4 is reflected by a reflecting container wall, so that the reflected fluid is left radiated intact at the outside of the container. As a result, propulsion force will occur in the direction having connected the rotor shaft 1 and the reflecting container center 4a.

Title: Keyboard encoder
Inventor: TSUTSUMI TOSHIYUKI
IPC: H03M11/04
Filed: 1990-04-24
Abstract: PURPOSE:To execute key operation by supposing the keyboard of new key arrangement to be the keyboard of practiced key arrangement by providing a means capable of changing optionally a fixed key matrix map. CONSTITUTION:At the time of scanning a key matrix, the connected or disconnected state of a key corresponding to a key number after change for an old key number is detected by using a key matrix converter to change the key matrix map. For instance, six pieces of the key numbers (old key number) of the inputs A5 to A1 and A0 of the key matrix converter 7 are converted one to one into six pieces of outputs D5 to D1 and D0 (key number after change). Accordingly, if the key matrix converter 7 is made to intervene in an old keyboard encoder, the key to be a detected object can be changed from the key corresponding to the old key number to the key corresponding to the key number after the change. Thus, the keyboard difficult to key operate can be supposed to be the keyboard of the key arrangement familiar to oneself.

Abstract: PURPOSE:To prevent the deterioration of the holding of a memory with the increase of the degree of integration by forming a gate electrode on the laminated thin-films of Si and Si3N4, forming socuce-drain, implanting H ions and increasing H contents in Si3N4. CONSTITUTION:An Si3N4 mask 3 is superposed on an SiO2 film 2 on a P type Si substrate 1, and a field oxide film 4 is formed. The films 3 and 2 are removed through etching, the surface is coated newly with an SiO2 film 5, an Si3N4 film 6 is shaped at 800 deg.C through a decompression CVD method, and a poly Si gate electrode 7 is attached. A source 8 and a drain 9 are formed through the implantation of P ions, and the electrode 7 is conducted. The surface is coated with a CVD SiO2 film 10, and the film 10 is compacted, the source and the drain are pushed in and the electrode 7 is annealed at 1,000 deg.C in N2.

Abstract: PURPOSE:To provide a physical feeling sound having no feeling of physical disorder through rapid release of a masking of a physical feeling sound owing to vibration during running by providing a vibration sensor to generate a vibration signal having intensity responding to vibration of a car body and regulating the level of an input signal according to the average level of the vibration signal. CONSTITUTION:When a vehicle is started to run and the generation of vibration is increased, the level of an output signal from a sensor 10 is increased. An integrating circuit 11 reduces a damping amount of a level regulating means 9 according to the increase of the level of the output signal and control is effected so that the level of a signal inputted to a low-pass filter 5a is increased. Further, control is performed so that the integrating circuit 11 causes the increase of the cut-off frequency of the low-pass filter 5a. Thus, since the level of a signal inputted to an amplifier 6 is increased, physical feeling sound vibration generated by a physical feeling acoustic unit 8 is also increased.

Abstract: PURPOSE: To provide a telephone line interface. CONSTITUTION: A 1st transistor Q1 is arranged in series with a signal line 3, a 2nd transistor Q2 is arranged in parallel with telephone lines 3 and 4, and both the transistors are controlled by a control circuit 5. When the voltage on the telephone lines is lower than a voltage required for keeping the 1st transistor Q1 in ordinary conductive state, the 2nd transistor Q2 maintains a signal path. In order to reduce crossover distortions, a negative feedback loop (Q5, R1, Q3 and Q1) and a supply voltage detecting means 6 control the 1st transistor Q1, so that only a zero input current sufficient for supplying power to the circuit is conducted by the 1st transistor Q1 and the remaining current can be conducted by the 2nd transistor Q2. Thus, both the transistors in the conductive state are maintained at a low zero input line current level.

Abstract: PURPOSE:To set time till a PLL circuit is locked within prescribed time by sending a signal including usually a low frequency component to the PLL fast to decrease a time constant of the PLL circuit for prescribed time at the application of power. CONSTITUTION:At application of a power voltage Vcc, a spike pulse voltage is applied to a switch circuit 37 via a capacitor C1 and a resistor R1 to close the circuit 37 for a time (t). Resistor R3, R4 are connected in parallel for that time. The resistance of the resistor R4 is selected smaller than the resistor R3 and the time constant of an LPF 15d is changed smaller in response to the resistance selection to quicken the response speed of a phase comparator circuit 15c and the PLL circuit 15 transits to the locked state at a high speed for the time (t) simultaneously when the power is supplied. After the lapse of the time (t), the circuit 37 is set to the open state and the resistor 4 is removed and the LPF 15d is operated at a higher time constant than before depending on the resistor R3. The large time constant is used to generate a stable DC voltage with respect to the signal having a low frequency component thereby controlling a VCO 12a.
