Title: Video tape recorder for teletext signal
Inventor: HONJO MASAHIRO
IPC: H04N5/92
Filed: 1984-07-13
Abstract: PURPOSE:To record and reproduce securely a teletext signal by replacing a video signal with memory information of a memory circuit so as to be a composite signal, then recording it and reproducing and outputting selectively a teletext broadcast section where the drop-out will not occur at reproduction. CONSTITUTION:A reproduction video signal A inputted from an input terminal 6 is transmitted to a control circuit 9, memory circuit 7 and switch 10. On the other hand, a dropout signal B is inputted to the circuit 9 from a terminal 11, and produced when a reproduction envelope drops to an extremely low level. The circuit 9 generates a control signal C, muting signal D and switch signal E, which are used for controlling the circuit 7, muting circuit 8 and switch 10. Memory information in the circuit 7 is transmitted to an output terminal 12 through the circuit 8 and switch 10, replaced with the signal A and synthesized, thereby obtaining an output signal F.

IPC: H03K19/00
Filed: 1987-06-15
Abstract: PURPOSE:To make it possible to observe a signal, which passes in a narrow place or in a tightly closed place, by forming a minute probe, attaching the probe to an electronic circuit, operating the electronic circuit, and observing a signal which is obtained through a coaxial cable that is led out of the probe. CONSTITUTION:A transistor 4 is brought into contact with a signal for observing an earth 1 for observing the signal of a probe head 9, on which a high clamping resistor 3 is mounted. A coaxial cable 5, a terminating resistor 7 and a DC power source 8 are connected between the collector and the emitter of the transistor 4. The transistor 4 is made to be in an active state. A signal to be observed passes through a signal observing terminal 2 and drives the base of the transistor 4. Then, a signal which is analogous to the signal to be observed is generated at the emitter of the transistor 4. The signal, which is generated in the emitter, is terminated at the terminating resistor 7 through the coaxial cable 5. When an observing terminal 6 is observed with a high impedance probe, the signal which is analogous with the objective signal can be observed. The observation of the signal waveform in the electronic circuit becomes easy.

Title: Friction material
Inventor: MISAWA NORIO
IPC: F16D69/02
Filed: 1990-06-05
Abstract: PURPOSE:To prevent a mate friction material from its transfer to a friction material by constituting metal powder of at least one of niobium and thallium, in the friction material which contains inorganic filling material powder and the metal powder of 10w/m.k or more heat conductivity and has an iron group metal as the friction mate material. CONSTITUTION:At least one of niobium and thallium is used as metal powder contained in a friction material. In both the niobium and the tallium, a melting point is remarkably higher than that of copper and iron. Accordingly, a phenomenon, in which iron of a friction mate material is partially transferred to a surface of the friction material to adhere is a dispersed point state, is prevented, so that durability is improved by reducing wearing of the mate material. Heat conductivity of both the niobium and the thallium is in a high value, and a stable coefficient of friction can be held even at a high temperature by maintaining heat radiating action.

IPC: F03B17/00
Filed: 1979-11-13
Abstract: PURPOSE: To take off power only with the open-close operation of valves, by dividing a vessel into two spaces and mounting the valves, a water drain pipe, piston and spring to the vessel.  
     CONSTITUTION: A vessel 1 is divided into two spaces 8, 9 to which valves 5, 6, 7 water drain pipe 2, piston 3 and spring 4 are mounted. If water is filled in the vessel 1 to open the valve 5, the spring 4 is contracted by the pressure of the water to raise the piston 4. Then if the valve 5 is closed and the valve 6 is opened, the spring 4 is extended to lower the piston 4. At this time, air goes into the space 9 to drain water in the space 9 from the water drain pipe 2 and lower the level of water in the space 9. And if the valve 7 is opened in a state with the valves 6, 5 as closed, the level of water in the vessel 1 reverts to the former condition. In this way, only the open- close operation of the valves 5, 6, 7 can take off power.

IPC: H04N5/91
Filed: 1990-06-06
Abstract: PURPOSE:To prevent the change of luminance from standing out conspicuous by calculating the average of plural reference levels, calculating the deviation in the reference levels from this average for each time when reading in a reproduction reference pulse, and using for correcting levels the value calculated after the deviation value is added to the value of the reference pulse. CONSTITUTION:A microcomputer 16, after initialization, reads in the serial reference levels from a reference level storing means 15, and calculates their average, for each time when a characteristic correction signal is reproduced. Then, the value calculated after the average is subtracted from the latest reference level is momentarily stored as a reference pulse correction value. Next, the height of the reproduction reference pulse is read out from the reference pulse storing means 13, and again stored momentarily as a correction reference pulse data after the said reference pulse correction value is added to it. Like this, the content of a level correction means 8 is updated by using the value calculated after the reference pulse correction value is added to the read out reference pulse data so that the state of the level correction cannot rapidly be changed and the continuity can be held.
