Title: Turbosupercharged engine
Inventor: HITOMI MITSUO
IPC: F02B37/02
Filed: 1985-10-30
Abstract: PURPOSE:To reduce an energy loss in an exhaust passage leading to a turbine as well as to aim at improvement in supercharging efficiency at a low speed range, by dividing a flow of exhaust gas, which has the turbine bypassed at the time of high speed, in and around an exhaust port. CONSTITUTION:An exhaust passage 6a of an exhaust manifold 6 for respective cylinders 2a-2d is branched off into first exhaust passages 7a-7d and second exhaust passages 8a-8d. Downstream ends of the first exhaust passage are converged together and interconnected to a turbine 14, while the second exhaust passage is interconnected to a bypass passage 11 via bypass valves 10a-10d. With this constitution, exhaust gas to be bypassed by these bypass valves will not pass the whole stroke of these exhaust passages to the extent of the turbine, so that there is no increase in passage resistance, thus these exhaust passages are throttled and supercharging efficiency at a low speed range is improvable.

Title: Manufacture of engine subcombustion chamber
Inventor: SHIGETSU MASAHIKO
IPC: F02B19/16
Filed: 1985-10-31
Abstract: PURPOSE:To reduce the tensile stress acting on the lower ceramic member by forming a space between an upper ceramic member forming a subcombustion chamber together with the lower ceramic member and an outer cylindrical member which is fitted on the outer circumferences of these ceramic members. CONSTITUTION:The ceramic member 16 forming a subcombustion chamber 15 is made so as to be divided into upper and lower ceramic members 17 and 18 respectively. And the upper ceramic member 17 is superposed on the lower ceramic member 18, and an outer cylindrical member 20 which is formed by pressing sintered alloy powder is fitted on the outer circumference of the ceramic member 16, and further a heat insulating material 21 is filled in the space between these. then the outer cylindrical member 20 is heated to be sintered and shrinked, so that the upper ceramic member 17 is restrained by the inner circumferential arc surface 20c of the outer cylindrical member 20 and further the lower ceramic member 18 is restrained by a lower inner circumferential surface 20d and a projection 20e. Since the outer cylindrical member 20 shrinks at this time only in the downward direction due to the space between the upper ceramic member 17 and itself, the expected purpose can be achieved.

IPC: H02P29/00
Filed: 1984-11-20
Abstract: PURPOSE:To accelerate the response of a motor by continuously exciting the motor when the rotation of the motor is lower than a reference speed and delayed from the prescribed value, and continuously interrupting the excitation of the motor when the rotation of the motor is higher than the reference speed and earlier than the prescribed value. CONSTITUTION:A speed comparator 1 outputs a signal S2 of 'L' in case of speed signal S1>set speed signal Ss, and of 'H' in case of S1<Ss. A charger/ discharger 2 charges when the signal S2 is 'H' and discharges when 'L' to output a signal S3. A comparator 3 compares the signal S3 with a triangular wave S4, and outputs a pulse width control signal S5. A comparator 12 outputs a signal S7 becoming 'H' when the signal S3 becomes higher than the signal S6. When the signal S2 is 'L' and S7 is 'H', the signal S9 becomes 'L', and an input to a driver 4 always becomes 'L'. When the signal S2 is 'H' and S7 is 'L', the signal S5 becomes 'L', and the input to the drive 4 always becomes 'H'.

Title: Diversity receiver
Inventor: SASAKI KAZUTOSHI
IPC: H04B7/08
Filed: 1985-11-01
Abstract: PURPOSE:To improve the AM reception sensitivity of a diversity reception system by coupling all antennas of an AM/FM receiver with the input terminal of an AM receiver in common through choke coils for FM band cutting. CONSTITUTION:Plural antennas ANT1 and ANT2 are arranged where FM-band diversity reception is possible, and either antenna is selected by an antenna switching circuit SW to outputs a signal from an FM receiver RV1. Its switching signal is outputted from the receiver RV1. The antennas ANT1 and ANT2, on the other hand, are connected to an AM receiver RV2 through chock coils L1 and L2 for FM-band cutting. A mixer MIX sends the audio output of the receivers RV1 and RV2 to a common speaker system. The coils L1 and L2 prevents the receiver RV2 from placing a load on the receiver RV1 and separates the antennas from each other during FM reception. Consequently, when the AM/FM receiver employs the diversity reception system so as to improve FM reception performance, the sensitivity of FM reception is improved.

IPC: G11B5/64
Filed: 1983-12-29
Abstract: PURPOSE:To manufacture a recording medium for vertical magnetic recording having excellent sliding property and magnetic characteristic without decreasing the magnetic characteristic by adding approximately uniformly carbon to a magnetic layer.
