Title: Combustion chamber structure for diesel engine
Inventor: KANEKO HIROAKI
IPC: F02B23/04
Filed: 1981-01-22
Abstract: PURPOSE:To improve the mixing of the air and the fuel, by utilizing the suction, exhaust valves at the top of the cylinder to form a sub-combustion chamber at the position in a piston head coinciding with the main combustion chamber thereby producing a strong spiral flow and providing the function for directly injecting the spiral flow. CONSTITUTION:A main combustion chamber 7 comprising a tubular recess 6 is formed at the position facing with the valve head 5' of a piston head 3' while a tubular member 8 opening to the piston 3 side is projected at the tip of the valve head 5' thus to form a sub-combustion chamber 9. While a plurality of holes 10 are made circumferentially in the thick section 8' of the tubular member 8 and a groove 11 conductable to said hole 10 is formed around said recess 6. Consequently under compressing stroke the air in the cylinder 1 is compressed into the tubular member 8 then directed to the circumferential direction through the hole 10 and injected to produce the spiral flow. When the piston 3 rises to fit the recess 6 and the tubular member 8, the main and sub-combustion chambers 7, 9 are conducted to produce the highly compressed spiral flow resulting in the improvement of the mixing of the air and the fuel.

Abstract: PURPOSE: To obtain a magnetic head formed in such a manner that the coercive force of film does not increase, the productivity is not impaired and the core efficiency is increased and a process for producing such magnetic head. CONSTITUTION: U-shaped grooves 3 are formed in a direction orthogonal to plural approximately V-shaped grooves 2 formed in parallel on a nonmagnetic substrate 1. Soft magnetic thin films 4 are formed on the one-side slopes of the grooves 2. A low melting glass 5 is filled in the peak point parts of the slopes of the grooves 2 and the grooves 3 and is ground until the same height as the height of the peak points of the approximately V-shaped grooves is attained. The ground surfaces are mirror finished to form gap butt surfaces. The substrate is cut and gap material SiO2 is formed by a sputtering method, etc., on the gap butt surfaces to form a substrate block 6. The gap butt surfaces of the two substrate blocks are mated and the low melting glass 5 is melted in such a manner that the soft magnetic thin films 4 face each other via the gap material to form a core block 12.  The core block 12 is cut to obtain head chips 10.

Title: Pulse width modulator
Inventor: KURATA TAKATSUGU
IPC: H04N9/12
Filed: 1984-01-24
Abstract: PURPOSE:To obtain satisfactory picture quality by utilizing even an A/D convertor with the comparatively small number of bits by making the variation in pulse width per bit smaller for an image signal with low luminance, and setting the variation per bit larger when luminace become larger. CONSTITUTION:When a bright image signal is preset in a presettable counter 50, a saw-tooth-wave voltage becomes higher and the oscillation period of a voltage controlled oscillator 51 becomes shorter. When a dark image signal is preset, the variation of pulse width per bit becomes smaller and an oscillation period of the oscillator 51 becomes gradually longer. When a video signal is bright, the variation of pulse width per bit becomes larger. If an oscillation period of the oscillator 51 change linearly, the pulse width of the pulse-width-modulated video signal is in proportional to the square of a digital video signal. When a video signal is operated by the pulse modulator, it is possible to provide characteristics to an luminance output with respect to the input as the overall picture display device.

Abstract: PURPOSE:To improve the availability of a bus by varying the activation timing of the write/read control signals to a memory and an I/O in accordance with the value stored in a register. CONSTITUTION:A register 2 stores the value that is used for setting a blank period lasting until an I/O control signal is applied at the I/O cycle start. A state generating circuit 3 inputs a clock CLK 5 of a square wave signal, an access request signal 6 which starts a bus cycle, a READY signal 7 serving as an external terminal, and the contents of the register 2, At the same time, the circuit 3 outputs a state S1 signal 8, a state S2 signal 9, and a state SI signal 10 to a bus control circuit 4. The circuit 4 decides the change timings of an address bus 11, a memory, and an I/O control signal 12 based on the signal state of a state signal group. Thus a programmer is not required to consider the insertion of a NOP instruction, etc., in an I/O cycle just by setting the desired value to the register 2.
