These fibers are carbonized under pressurizing or pressing to obtain the fiber molding having 0.1-1.8g/cc bulk density. The matrix formed by chemical vapor deposi tion and/or the matrix consisting of pitch as a starting raw material is then compounded with this fiber molding. The thermally decomposed carbon is deposited with hydrocarbon such as methane or ethane as a raw material on the fiber molding in the chemical vapor deposition. Carbonaceous pitch is impreg nated in the fiber molding and the molding is thereafter carbonized in the case of the matrix consisting of the pitch as a starting raw material.

Title: Smoke detector
Inventor: OOTA KAZUOMI
IPC: G08B17/10
Filed: 1984-02-14
Abstract: PURPOSE:To detect smoke highly sensitively, by detecting the scattered light from the smoke by a light receiving element, comparing the average value of the output signals with the latest output signal, and stabilizing the signal with respect to the fluctuation of signal levels other than the smoke. CONSTITUTION:Light from a light emitting element 13 is reflected by smoke, and the reflected light is sent to a light receiving element 14 and converted into an electric signal. The output signal is amplified and inputted to a sample and hold circuit 17. The output is inputted to a differential amplifier 20 through a resistor 18. Its output is inputted to a comparator 21. The voltage of the output signal is indicated on the side A of a Figure (b) when the smoke is not present. The voltage is indicated on the side B when the smoke is present. When the smoke is not present, the voltages at points (c), (d) and (e) in the circuit have the same value. When the smoke is present, the voltage 32f is amplified as shown in the Figure (b) by the discharge of a capacitor 19 and the differential amplifier 20. When the smoke is detected, the difference between the volage 32f of the output signal of the comparator and an average output voltage Vth is obtained, and warning is issued. Since the output is obtained from the differential amplifier only when the smoke is detected, the smoke can be detected highly sensitively.

IPC: H03M9/00
Filed: 1987-02-09
Abstract: PURPOSE:To make the provision of a counter unnecessary, by providing an FF which inverts and holds the least significant bit of a parallel data, detecting the completion of a conversion operation by the propagation of the above n-bit values from a first bit to the (n-1)-th bit of a shift register of n-bits, and generating the next parallel load signal. CONSTITUTION:When the parallel data is set at the shift register 1 of n-bits, the inverted data of the least significant bit of the above data is set at the FF4. Afterwards, the data inputted to the register 1 is shifted out in order, and simultaneously, the bit value held by the FF4 is inputted to a final stage. At a time when an n-th bit is shifted to the most significant bit, the data from the (n-1)-th bit to the least significant bit becomes the same data as that of the FF4. A coincidence circuit 3 detects the above state, and recognizes it as the completion of conversion, and generates the parallel load signal on the register 1 with the next clock. Hereafter, the above operation is repeated at every n-bits.

Title: Compression ratio variable equipment of internal combustion engine
Inventor: KONDO TAKEHISA
IPC: F02B75/04
Filed: 1987-02-09
Abstract: PURPOSE:To prevent collision between an outer piston and an inner piston and attain better lubrication and cooling for various portions by providing a spool valve which can open or close every passage in response to a supplied oil pressure in a distribution hole formed in a compression ratio variable piston. CONSTITUTION:When a supplied oil pressure stays at a prescribed low pressure, a port 30 only is connected with a distribution hole 29 and pressure oil is supplied to an upper hydraulic chamber 22 and an outer piston 20 keeps the position of a high compression ratio. Since a lower hydraulic chamber 25 is in air tight condition at this time, its collision with the inner piston is prevented, even though the outer piston 20 moves itself in response to an inertia force. When a supplied oil pressure stays at a prescribed high pressure, a spool valve 52 is moved toward the left, ports 34, 33, 31 are opened, the pressure oil is supplied to the lower hydraulic chamber 25, and the outer piston keeps the position of a low compression ratio. At this time, the pressure oil in the distribution hole 29 flows into an annular recessed portion 51 located at the top of the inner piston 21 through the port 33, and flows out to the outside through the port 31. Therefore, the lubrication and cooling around the outer/piston is enhanced in a high load area with a big calorific value of an engine.
