Title: Cylinder block structure of engine
IPC: B22D19/08
Filed: 1992-03-30
Abstract: PURPOSE:To improve deposition performance between a cylinder liner and a cylinder block main body part without reducing abrasion resistance performance of the cylinder liner in the cylinder block structure of an engine in which the cylinder liner having abrasion resistance performance is inserted in aluminium alloy. CONSTITUTION:In a higher position than a position at the time of the top dead point of the piston of a first piston ring 7 (top ring), thin wall parts 1b to 3b having smaller diameters than cylinder liner main body parts 1a to 3a in its outer circumferential part, are formed in the vicinity of top end parts of respective cylinder liners 1 to 3. It is thus possible to improve deposition performance between respective cylinder liner 1 to 3 and a cylinder block main body part 4. First and second slits 11, 12 whose both end parts are communicated with respective first and second water jackets 13, 14, are formed on respective top end parts 4a, 4b of the cylinder block main body 4 between respective cylinder liners. It is thus possible to improve cooling performance around top end parts of respective cylinder blocks 1 to 3.

Title: Thermal head
Inventor: AOTO KAZUAKI
IPC: B41J2/355
Filed: 1986-03-31
Abstract: PURPOSE:To correct dispersions of resistance without providing special correcting circuits, by providing one additional input terminal for each driver incorporated in a thermal head, and inputting to the additional input terminal a pulse having a width corresponding to the resistance of a heat generating resistor driven by the driver, thereby controlling the time width for which the resistor is driven to generate heat. CONSTITUTION:Each of drivers 9000-9255 has three input terminals, and a correction pulse 8000-8255 is inputted to one of the input terminals. A latch output 2000-2255 is inputted to another one of the input terminals, and a strobe 31 is inputted to the rest of the input terminals. Where both the correction pulse 8000 and the latch output 2000 are '1' and the strobe is '0', the driver 9000 starts driving a heat generating resistor 4000 to generate heat when the logical product of the three signal becomes '1'. Though the heat generating temperature of the resistor 4000 is higher than that of a heat generating resistor 4255 because the resistance of the resistor 4000 is lower than that of the resistor 4255, a correction value 6000 is so calculated that the heat generating time of the resistor 4000 is shorter than that of the resistor 4255 and both of the resistors have the same heating value.

Title: Method of detecting signal tone of target sine wave
Inventor: KITAGAWA KAZUMI
IPC: G01H3/00
Filed: 1993-03-31
Abstract: PURPOSE:To remove DC error and a noise component generated by an A/D convertor to improve the detection accuracy by sampling plural times at different phase positions in each quadrant of a target sine wave. CONSTITUTION:Only a target sine wave f1 in an audio signal Sf1 outputted from a microphone 1 is passed through a band pass filter 2 to be transmitted to an A/D convertor 4 via an amplifier 3. The A/D convertor 4 converts the target sine wave F1 to a digital signal f2 to transmit it to a CPU 10. The CPU 10 samples the digital signal f2 in accordance with an interrupt timing pulse f3 outputted from an interrupt pulse generation circuit 5. The target sine wave f1 is sampled plural times in first, second, third and forth quadrants at respective phase positions different from each other by 90 deg.. When the sum of the absolute value of difference between the sums of values in the first quadrant those in the third quadrant and the absolute value of difference between the sums of values in the second quadrant and those in the forth quadrant is equal to or more than a predetermined value, it is judged that the detection is accomplished.

Title: Variable capacity swash plate type compressor
Inventor: TOJO KENJI
IPC: F04B27/08
Filed: 1987-03-30
Abstract: PURPOSE:To reduce the fluctuation of overall torque as well as to eliminate resonant operations between an engine and a compressor by arranging six cylinders at equal intervals on the same circumference passing through the locking section of a piston support, of a circle with center at a driving shaft. CONSTITUTION:When the main shaft 13 of a compressor is driven, both a drive plate 14 and a swash plate 12 are rotated, and a piston support 21 is thereby also rotated. As a result, each piston 31 is reciprocated within each cylinder 33 via each connecting rod 32, therefore, cooling medium is sucked in each cylinder 33 so as to be discharged to a discharge chamber 9 after having been compressed. In this case, six cylinders 33 are arranged at equal intervals on the same circumference passing through the locking section 26 of a piston support 21, of a circle with center at the main shaft 13. Owing to this constitution, the fluctuation of torque generated in each cylinder 33 is mutually composed for reducing the fluctuating amplitude of overall torque. The fluctuation of torque is generated six times per revolution for eliminating resonant operations between an engine and the compressor.

Abstract: PURPOSE:To vary Q of the titled filter by supplying a current proportional to each differential amplifier output current of the 3rd differential amplifier means to 1st and 2nd differential amplifying means as a constant current source current via a current mirror means so as to vary properly the constant current source current of a 3rd differential amplifying means and the other input voltage CONSTITUTION:The total constant current source currents (I1+I2) of the 1st and 2nd differential amplifying circuits 31, 32 is changed by varying a resistance of a variable resistor R5 and a center frequency f0 is changed. In varying the resistance of a variable resistor R21, the base potential of a transistor (TR)Q22 is changed.

Abstract: PURPOSE:To steadily maintain contact pressure between a gasket and a negative cap to increase electrolyte leakage resistance by specifying outer-diameter deformation rate of a negative cap by control of crimping pressure for battery sealing. CONSTITUTION:A negative cap 3 is pressed into a through hole 11a of a fixture 11 to deform it in an outer-diameter direction, and recovering rate from deformation and permanent deformation are measured.
